Phoenix Mars Lander. Discuss.
First post?
Or not… Space bugs me. It makes me feel insignificant.
(3) I often find that comforting myself.
The universe: can it exist?
How fitting! I’ve just been re-watching the Star Wars series. We just got a new Star Trek DVD, too, and we’re going to start that this summer. Of course, we can always talk about the real space, but fiction is fun
I’m excited about the Phoenix Mars Lander, though. It’s scheduled to land next week, isn’t it?
5–I hope so. Otherwise we’re all just hallucinating. Or maybe I’m imagining all of you.
Do you want to sing to my cat?
3–Space doesn’t so much make me feel insignificant as it makes me feel…correct. Like it’s all right if I mess up, the universe will still be there. It’s a constant view of perfection.
Phoenix Mars Lander? Phoenix Mars Lander? I feel ignorant…could someone fill me in?
8- It launched from The Cape on August 4rd, 2007 and it’s been traveling towards Mars ever since. On May 25, it will touchdown near the North Pole of Mars and investigate the ice caps.
This is important because:
1) Life on Earth needs water, and we know there’s water there, even if it’s frozen, it’s still worth a look.
2) The presence of water would make this a good site for a future base.
9-thanks. It sounds cool.
9 – Cool.
I wish Star Wars was somewhat realistic. Wait. It IS real. What am I talking about? *slaps self*
I love the idea of infinity. Its daunting, but its also so beautiful. Something with no end. Time infinity is downright disturbing, but space infinity…
Anyway, who prefers inflationist theory and who likes Classical Big Bang, not that they contradict eachother too much, if you ask me!

I like the idea of the universe being so big. It seems protective, like being a little kid hiding under the stairs or something.
I love looking at the stars.
Oh… Infinity… Big..
Orion is my favorite.
I love stargazing.
4- Comforting? It makes me feel… stupid, I guess.
Thankyou so much GAPAs! I don’t know why still but, poor pluto
Sorry for the double post
1- here is an article about that, from the NASA website
WASHINGTON — NASA’s Phoenix Mars Lander is preparing to end its long journey and begin a three-month mission to taste and sniff fistfuls of Martian soil and buried ice. The lander is scheduled to touch down on the Red Planet May 25.
Phoenix will enter the top of the Martian atmosphere at almost 13,000 mph. In seven minutes, the spacecraft must complete a challenging sequence of events to slow to about 5 mph before its three legs reach the ground. Confirmation of the landing could come as early as 7:53 p.m. EDT.
“This is not a trip to grandma’s house. Putting a spacecraft safely on Mars is hard and risky,” said Ed Weiler, associate administrator for NASA’s Science Mission Directorate at NASA Headquarters in Washington. “Internationally, fewer than half the attempts have succeeded.”
Rocks large enough to spoil the landing or prevent opening of the solar panels present the biggest known risk. However, images from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter, detailed enough to show individual rocks smaller than the lander, have helped lessen that risk.
“We have blanketed nearly the entire landing area with HiRISE images,” said Ray Arvidson of Washington University in St. Louis, chairman of the Phoenix landing-site working group. “This is one of the least rocky areas on all of Mars and we are confident that rocks will not detrimentally impact the ability of Phoenix to land safely.”
Phoenix uses hardware from a spacecraft built for a 2001 launch that was canceled in response to the loss of a similar Mars spacecraft during a 1999 landing attempt. Researchers who proposed the Phoenix mission in 2002 saw the unused spacecraft as a resource for pursuing a new science opportunity.
Earlier in 2002, NASA’s Mars Odyssey orbiter discovered that plentiful water ice lies just beneath the surface throughout much of high-latitude Mars. NASA chose the Phoenix proposal over 24 other proposals to become the first endeavor in the Mars Scout program of competitively selected missions. “Phoenix will land farther north on Mars than any previous mission,” said Phoenix Project Manager Barry Goldstein of NASA’s Jet Propulsion Laboratory, Pasadena, Calif.
“The Phoenix mission not only studies the northern permafrost region, but takes the next step in Mars exploration by determining whether this region, which may encompass as much as 25 percent of the Martian surface, is habitable,” said Peter Smith, Phoenix principal investigator at the University of Arizona, Tucson.
The solar-powered robotic lander will manipulate a 7.7-foot arm to scoop up samples of underground ice and soil lying above the ice. Onboard laboratory instruments will analyze the samples. Cameras and a Canadian-supplied weather station will supply other information about the site’s environment.
One research goal is to assess whether conditions at the site ever have been favorable for microbial life. The composition and texture of soil above the ice could give clues to whether the ice ever melts in response to long-term climate cycles. Another important question is whether the scooped-up samples contain carbon-based chemicals that are potential building blocks and food for life.
The Phoenix mission is led by Smith with project management at JPL. The development partnership is with Lockheed Martin, Denver. International contributions are from the Canadian Space Agency; the University of Neuchatel, Switzerland; the universities of Copenhagen and Aarhus, Denmark; the Max Planck Institute, Germany; and the Finnish Meteorological Institute.
Awesome isn’t it? I went to the Kennedy Space Center and the guide talked all about it.

I believe, as do many scientists, that the universe has no boundaries but is not infinite. You can never get to the “edge,” because there is none, but it is limited. Think of it like a sphere. It has no edges, but is limited.
Oh, and Space Shuttle Discovery takes off on the 31th.
13-Inflationist, I think. Infinity freaks me out, and makes me feel so insignificant.

Oh…space makes me feel dizzy just thinking about it.
I like inflationist, because its the only theory that properly covers the big gaping hole in classical Big Bang: how could we have gotten something out of nothing?
I like inflationist, because its the only theory that properly covers the big gaping hole in classical Big Bang: how could we have gotten something out of nothing? Quantum fluctuations and all that jazz…
I try to avoid any theories regarding the creation of the universe, but I agree with Piggy’s description of the current universe.
Of course, we cannot avoid the great question- Are we alone?
I say no, but that’s just my opinion. I believe Phoenix will find something; not any intelligent life, but life nonetheless.
Then again, we’ll find out soon, won’t we?
Can someone explain what each of the theories are?
inflationist? *feels terribly confused*
27- I hope Phoenix will find life, but I doubt it’ll happen. Too cold, no breathable gases, and no water. I mean, there could be water, but we haven’t found any. Unless I’ve missed some great new discovery.
Life! Oh, what a great topic!
Mars? Mars is a great place in space…
To think of life on it…
I hope the Phoenix will find life!
Since the Cassini is near its mission’s end, maybe I could research the Phoenix!
*sniffle*
Titan…
31- Titan’s cool. Didn’t they give Cassini a few more years, though? Finding microbial or bacterial life on Mars would be SO awesome!
31- just RNA would be cool!
Is it Robert’s feild or Roseanne’s Feild? (Listen musecast 8 for more info)
Well, I handle planets, but Rosanne handles life. Life on other planets is pretty much up in the air right now. If they discover any, I suppose Rosanne and I will pie each other for it.
‘If they discovery any’?
This would be a very good place for the galaxy song.
35- Let me guess “Intelligent life on other planets?” “There’s none on this planet.”
Oldest joke ever, wasn’t even that funny to begin with.
30- Microscopic life doesn’t need that much to live, and it’s still life.
36- But there is none, you realize.
Planets….
I like Neptune.
30, 37- Fine, but I still doubt it.
37- Come on! You have to give us humans some credit!
My favorite planets are Mars and Saturn.
Oh, and can we get Discovery on the calendar, please?
I think the most likely candidate for life (probably microscopic) in the solar system is Europa.
41- Europa’s very promising. They could have jellyfish under that ice, or even tube worms.
I feel confuzzled. And whang-doodled.
I need to improve my vocabulary, don’t I.
KaiYves, what is the Constellation program? I gathered from your previous posts that it is to replace the space shuttle.
44- The Constellation program is NASA’s next step. The Constellation vehicles will be able to dock to ISS and, when launched on the powerful Ares 5 rockets, reach the moon.
Timescale:
2010- Shuttle stops flying
2010-2014- Kai goes crazy from boredom
2014- First Constellation flights
2020- BACK TO THE MOON!
2035+- Mars
We all might be dead in 2036. Sorry to break it to you guys.
42- Yes I think Europa will prolly have life.
The reason for the first statement:
Anybody who watches “The Universe” will know what I’m talking about. In 2029, Friday the 13th, a meteor named Apothos will pass so close to Earth that one will be able to see it with the naked eye.
Apothos has over a 99%chance of missing the Earth in 2029. But if Apothos passes the Earth at a distance of exactly 18,893 miles, it may pass through a gravitational key hole than Earth’s gravity will upset Apothos and it will return and hit Earth 7 years later. But luckily theres a very small chance of it hitting us. Hehe, but it’s still CREEPY!
39- Well all the idiots cancel out the smart people.
45- Come on, they have to do something for 4 years.
The Russians will still be sending people up in their Soyuz capsules, I assume. And, of course, satellites and robot probes will still be going into space on regular rockets.
46 – Before I noticed your atrocious grammar (“Prolly”?) I must ask why we might be dead in 2036. Stay positive!
46- I thought it was called Apophis.
46 – We’re all going to die in 2012 anyways. (Sorry – I just had to mention it. )
(46) “Prolly” isn’t bad grammar, just sloppy pronunciation. And considering the way languages evolve, I’d say it’s almost certainly the wave of the future.
(51) Oh, we are not.
52 – We are too.
My social studies class literally spent our 90 minute class discussing end of the world theories once.
Hm, sounds as if you’d enjoy the article on end-of-the-world theories that I wrote for the December 1999 issue of Muse. It may be the best thing I’ve done for the magazine. I was a bit hard on Nostradamus, I’m afraid.
Hold on — I’ve just remembered that you can read it on the Fan Page, though without the lovely End of the World time line that the editors helped me prepare.
no, it’s 2060 by newton.
Aren’t we a bunch of earthlubbers? (As in landlubbers in pirate talk.)
54 – I know, I was thinking of that issue at the time. I didn’t know it was on the Internet, though, so I guess I’ll go read that.
46-Maybe Eurpa has life(hmmm, I will have to research that) But I still think Titan has microscopic life under its surface… I am a Crazy Titan Nerd afterall.
46- Yes, that’s why the Planetary Society is conducting extensive research into asteroid deflection. On the off chance that Apophis does pass through that keyhole, here are some of the things we could do:
1) Drive it off course with a missile (NOT blow it up. Blowing it up would be really hard and the pieces would still be headed for us.)
2) Attach rockets to it, and fire them all at once, again to drive it off course
3) Darken one side of it with paint or something so that the uneven heating would- again- drive it off course.
58-I don’t want it to hit us! *Runs and Hides*
Don’t worry. Us Americans will probably nuke it into oblivion, and the world will be saved by the friendly neighborhood overly pretentious capitalist superpower!
58- that third one, intill I read the last part, was funny. “Darken one side with paint. Don’t know what this will do, but it will look nice.”
!!!
It’s Hitting L.A.! *Notes to go to second house in 2046.*
The other option, of course, is to let it hit us. All large life can die off and evolution can start again. When insects build museums they can include an exhibit on Muse.
59- That’s the point I was trying to make. It won’t, because even if it does pass through the keyhole and become a potential danger, we will deflect it. And (60) the world will be saved by the friendly neighborhood spacefaring nations/alliances- US, Russia, Japan, China and the European Union.
62- True, but we won’t be around to enjoy it.
If the universe is a sphere, are we on the inside of it or the outside?
64- yes, but think of all the happy little beetle larve.
65- I heard a theory that we were living on the surface of a 4D hypershere.
Inside, I think… *Muses*
65- Inside.
Fun fact: Until 1977, scientists thought that there could not be life in the deep oceans, where no sunlight penetrates. Then we found hydrothermal vents, places along the edges of tectonic plates where the Earth’s heat escapes into the water. There are many creatures that live in this environment, including Tube Worms and Vent Crabs. It is believed that similar environments might allow life to exist on Europa.
(65) Neither inside nor outside, as I understand it. If you draw a circle (say, the numeral zero) and pick one point on the loop, is that point on the inside or the outside? Neither: it’s on the circle. That’s where we would be, analogously, in a spherical universe, only with a couple more dimensions added. (That’s what Zyviva means by “the surface of a 4D hypersphere.”)
69- But– how– what– I don’t understand…
*brain implodes*
*calmly puts Alices brainback.*
Oh, nonsense: unfamiliar ideas do not make Musers’ brains implode. I just haven’t explained it very well. No time for that just now, I’m afraid. Maybe somebody else will do it.
It’s like living on the surface of Earth. You could think of it as flat, but it just goes in a circle. Also, if you went long enough, you would just go back to wherever you started.
That’s partly true: a curved surface does seem flat if it’s big enough (or if you look at a small enough patch of it, which is another way of saying the same thing). Living in a curved universe, however, isn’t like standing on the surface of Earth. It’s more like being part of the skin of a balloon.
Geometrically, a perfect balloon skin has no thickness. It’s a two-dimensional surface (like a plane) that wraps around through three-dimensional space and connects to itself again. In theory, a two-dimensional “shadow creature” could live on that surface, unaware that the balloon has an outside and an inside — in fact, unable to imagine a direction that would make the words “inside” and “outside” meaningful.
In the same way, we are three-dimensional creatures living in three-dimensional space. But it’s possible that our 3D space wraps around through 4D space and rejoins itself — just as the 2D surface of a balloon does. We can’t imagine that kind of curvature, but we can describe it mathematically. That’s what math is good for: getting answers about things that your brain can’t imagine (multidimensional curves, unknown quantities, really big numbers, etc.).
69-That reminds me oddly of a Mobus strip…
74-*begins to see the light* Beyond reminding me of Flatland, that made quite a lot of sense. Thanks!
This is terribly confusing. I think I need to do alot of research.
75- That was the hardest episode of Cosmos to understand, but it was still a great one!
Flatland is awesome. I never finished it, but what I read was great.
71- Thanks, TMFA. Now I can try to understand Robert’s new explanation.
And I do understand! So I wonder if we could pop out of the surface and into the interior of the balloon…or the exterior.
Hmm… *jots down notes*
77-Woot! Cosmos! The best ones were still the evolution sequence, natural selection, vespas and the red-shift, Sagan ranting about the danger of nuclear weapons, and everything else I forgot to mention, though!
78-I loved it, too! Flatterland was abysmal, though. Scratch that. The math was interesting, but there was no plot intertwined, which made it a little less fun to read. On pain of repeating the MA blog conversation, I will now desist from saying more on the subject of Flatland sequelse. But still…
80- The shot of the spider that fades out to the radio telescope is just brilliant camerawork.
76- Martin Gardner has some interesting things to say about hyperspacial geometric figures. However, it will probably not deconfuse you in the beginging becuase he assumes that you can read terms like 9-space without scratching your head. (9-space is simply 9D space, a 9-cube would be a 9D cube, etc.) First deconfuse yourself as best you can and then read Martin Gardner.
Three days until Phoenix!
And nine until Space Shuttle Discovery takes off!
And only a couple more years until the Space Shuttle is decommisioned!
78 – What? Flatland? Off to Google!
85- Yup, I wish I could see a launch in person.
Touchdown of Phoenix will be at 4:53 Pacific, 7:53 Eastern. Google “Time Zone Converter” if you live somewhere else.
85- You’re right, I need to get to one of those launches… I live about two hours away from the Cape and I’ve only been there once. And I was too young to remember.
88- AM or PM?
I got into an argument with acatholic in our class about the origins of the universe and about the bounderies if space. It was fun, since I was constantly messing with his head. And the teacher said that the big bang is believed by some ‘sects.’ Comforting to have an ignorant religious teacher. X(
88- PM.
90- Does that make Orthodoxy a sect?
90-Oh, so logic and science are sects, are they? …
This isn’t the religion thread, now.
88- 6:53 Museblog time. Is that today?
94- The 25th.
It’s tomorrow! It’s tomorrow! It’s tomorrow! It’s tomorrow!
95-Three Important Events on one day! May 25!
11 hours, 14 minutes to touchdown.
YEAH! This is a big day in history. I’ll go to the NASA website right now……………….
96-Three? What three?
ACK!!!!!!!!!!!!!!! PHOENiX MARS LANDER!!!!!!!!!!!!!!!!!! TODAY!!!!!!!!!!!!!!!!!!!!!
Just over an hour to touchdown. 7:47 PM Eastern is when the atmospheric entry begins. JPL staffers call it “Seven Minutes of Terror”.
NASA TV:
http: //www. nasa.gov/ multimedia/ nasatv/index.html?param= public
Awaiting news of the progress of a robot on a desert planet, I feel quite like Leia must have in Episode VI.
7:06 Eastern.
Go for entry, descent and landing.
These next twenty minutes are the big ones.
No more time for posting.
Time only now for watching and praying.
I’m watching, too. The propulsion system has been pressurized. We’ll know soon whether the cruise stage separates correctly…
Separation confirmed!
One more quick one…
In entry mode.
Five minutes to entry.
In the atmosphere, parachute opens in 3 minutes.
It’s in the atmosphere, and broadcasting!
Parachute deployed, heat shield jettisoned, 1100 meters…
TOUCHDOWN!
4:51-Gaaahhh!!! Couple more minutes!!!
4:54- YESSS!!!!! PHOENIX SUCCESSFUL!!!! WHOOHOO!!!!!*dances around whooping*
Phoenix has landed! Welcome to Mars!
All the blue-shirted people in the control room are hugging one another and punching the air. (And dashing for the bathrooms, I’ll bet.)
So am I, but I’m in a black shirt with an image of a galaxy on the front.
Yay! I got here and got the link to work just in time.
(112) All the blue-and-grey visuals are strangely hypnotic.
At 8:13 Eastern, we’ll know if the solar arrays have deployed.
At 8:43- 9:02, we can expect first data and maybe first pix.
Pleasure covering this landing with you, GAPA Coontz.
Likewise.
The first pictures will show the solar arrays. It could be a while before we get to see Mars.
I got to the stream!
Could be worse, Viking’s first pix were of its own footpads. Solar panels are cool.
and lost it.
(118) Well, it’s important to know that they’re working.
You and me both, TMFA. My internet connection has chosen tonight to start having hiccoughs again.
120-That it is. My, we’ve clogged up the Recent Comments…
First pix! Showing solar panels, robotic hands, footpads, and the Martian horizon!
ooh, ooh, where can I find the pictures Phoenix has taken? I’ve looked at the Nasa website…
Delinkified link:
http: //www. nasa.gov/ mission_pages /phoenix/ main/
Approximate color pix: nasa.gov/ mission_pages/phoenix/images/press/ false_ color_postcard_edr.html
You can really see how the terrain is different from where the rovers are!
124- On the NASA home page, right now it has the headlines “Phoenix on Mars, Sending Photos of Polar North” Then there is a picture below it. Click on the picture.
Mars Rocks!
Phoenix is unstowing its arm and getting ready to dig.
129-I saw the clip. I must confess, it was pretty magical.
I hope this isn’t too out of place in this thread:
The best explanation of time as the 4th dimension that anyone ever gave me (and here I must confess that it came from the otherwise annoying Flatterland) was as follows, to “be”, an object must exist in certain dimensions. There are only a few, however, that we, with our limited scope of understanding, are able to recognize: first, it must have what we qualify as the first-dimension, a “line”, second, it must have a surface”, thirdly, it must have height (no matter how infimitessaly small), and lastly, it must exist in time (it must last for a period of time to exist at all).
I thought this was so interesting and quite clear. I hope I have managed to synthesise it in atleast a fairly rational way.
I think you did explain it quite well.
130-I think I get it now! Thanks, Hypatia, (and Flatterland)!
131/132-Thank you…
Flatland does a fairly good job of explaining how the first three work with exponents, but doesn’t touch on tine…
Can this function as a general science/math thread so I can come running on to scream and cram the day before my 12 question science final, which I stand very little chance of doing well on as most of what we’ve learned this year has literally passed in one ear and out the other and may now be considered “gone with the wind”? Note the run-on.
You know what’s confuzzling? Quantum physics…
Yes it is! General math/science…
Sure, go ahead.
I think the real question isn’t if there is other life in our solar system, but in the rest of our galaxy and in other galaxies. If you think about it, it is just about impossible for there not to be life somewhere other than Earth.
On a different note, I think the universe is more torus-shaped than spherical. Quantum physics back that up way more. Oh, and I loves quarks. They’re like wungs’ baby brothers.
Yes, there’s probably no intelligent life in our solar system, but there certainly must be in the rest of the galaxy.
138-Not “must be”, but very, very probable…
139- Right, that’s what I meant.
Closer to home, the Discovery astronauts have installed the Kibo lab on the Space Station and will enter it later today.
138- There certainly isn’t any on Earth! *slaps knee and laughs deleriously, slowly quieting down and looking ashamed when no one else laughs*
140-Didn’t the toilet break on the ISS? I think I heard that somewhere.
141- No offence intended, but that was only funny the first time. Which was in Muppets in Space. When I was five.
And yeah, it did. Discovery brought up some plumbing supplies and they fixed it.
I know this is a space thread, but I desperately needed to post this somewhere, and well…space~science~math, in a vague and ambiguious sense?
Anyhoo,
There were quite a few good problems on our math final, and I wanted to post one here.
If a weighted coin (3/4 chance of heads) is flipped 10 times, what is the probability of coming up with exactly eight heads?
5 provisional points to whomever comes up with the answer first!
I also ♥ locuses!
Most people probably know this, but I thought it was fairly insanely cool when I first learned it: the official definition of a parabola is: “a set of points equidistant from a line and a point”. To provide a little extra clarification. A parabola is defined by a point (not on the parabola) and a line (that does not intersect with the parabola). Every point on the parabola is the same distance from the point and the line (ie. Point A is 3 away from the line and 3 away from the point, whereas Point B is 4 away from both line and point)!
That was one of Hypatia’s odd (and frequent rants). Do not feel compelled to read it!
143- Unless my calculations are incorrect, the coin has a 60% chance of getting exactly 8 heads.
143- Provisional Points?
I hate Math so much. It’s so boring :(. I mean I like Math outside of school (I mean the fun kind of Math), but in school, our Math class is SO BORING!
.At my school, our math curriculum is fun. It’s just, it’s only fun if you’re actually learning! It’s WAY TOO EASY! I’m sure it would be fun if it was the “right level” for you. For me, though, it’s not. I’m so glad next year I can be in some sort of honorsy thing, (new school) that might be better suited to me!
Math? But isn’t this a space thread?
*feels confused*
147- It’s been expanded to include Math and General Science. But you can still talk about Titan.
144-I’m not quite sure as I was far too lazy to compute the numerical answer, but, yet unsimplified, the asnwer is 3/4 to the 8th time 1/4 squared times 45…
Our math curriculum is SO EASY! We have this accelerated math thing. So people who pass this test can do 1 grade higher math. I’m in that, but it’s still easy. Then there is this Project Arrow thing which is two grades ahead, and that’s almost as easy as Accelerated Math. But math is so boring. The most boring subject no matter what. Even though math is very important to science. I love science. It’s always so interesting. Math is only fun when it’s in science. Otherwise, just plain old math is so boring.
150- true.
But I like Plain Math…
152-I also like plain math.
Somehow I ended up slipping into a meditative state during my last math test.
Hypatia is, at present, leafing through her notes on earthquakes and tsunamis and trying to find relevant information in the tumult (*coughdoodlescough*).
Report: Mission Failed.
Thank goodness for good ol’ reliable Wikipedia, always there to lend one a hand!
*is compiling study sheet*
Gar! Underwater subduction zone-generated earthquakes often cause tsunamis.
Why oh why? So much to learn, so little time!
So has anyone given the correct answer as of yet, Hypatia? I beg thee tell us!
157-I put the closest I have to an answer in 149. If anyone is willing to whip out a calculator and simplify … Anyway, I’m not 100% sure that I’m right. Maybe a mathly minded GAPA can sound in…
You’re welcome to provisional points regardless… !
I have a lot of problems grapsing the concept of waves, because its basically impossible to project them onto 2-d space. When a fairly large portion of your science final is CENTERED on p and s waves, you know this to be a problem… *sighs*
Hmm… It comes to about 28.156757354736328125%. But I’ll still take the points.
Here’s some cool science simulations from the University of Colorado. There’s some wave ones in there.
phet.colorado.edu/new/simulations/index.php?cat=Top_Simulations
159-You might well have been right too. However, intuitively, 60% feels like a little too much for so specific a qualification… Thanks for accepting the points!
I am DEFINITELY going to look at anything that will help me visualize waves! Thank you vury vury much!
Ahhhhhhh! *runs screaming through thread* *doubles back* *repeats strange exercise* *continues making spectacle of self*
Half-life+convectioncells+epicenters+acceleration+velocity+
density= a very very large muddle, speedily taking shape (as in “no shape”) in Hypatia’s over fatigued brain.
Ah well!
Here’s another fairly fun math problem:
*tries to think of way of expressing this problem without inserting square roots*. Okay so, assume everything is under one gienormous square root:
12+square root of 12 + square root of 12(now under original square root with everything and under square root of previous term and under own square root)+ square root of 12 (under square root over everything, square root from previous two terms, and own square root)…etc.
I’m awful at elucidating this sort of thing. Sorry if that makes no sense. I’ll try again later when the muddle has dissipated!
1.00000015?
162-Naw, sorry. Its a whole number. Although I think the fault is mine, not yours. It goes on infinitely…
Not that I described “it” very well, even without how long it goes on…
?????
*Feels hopelessly confused*
* has a headache*
Oh well…
I’m rather proud of myself at the moment. I just found a great website for HTML tricks:
[Sorry, iŹ√Ҳ!, but I zapped the external site… Rosanne]
Here’s an easy one:
If a hen and a half can lay an egg and a half in a day and a half, how many eggs can six hens lay in seven days?
166- I’m not good at math…
Umnm… 30 eggs?
166- 35.
166- I mean, 28 eggs…
i like electrons. They are both a particle and a wave, motionless and in motion at the same time, and can be in different places at once. *loves electrons*
I like mitosis. Every new cell formed by it is usually the same as the one that divided to form it, so every one of your cells is as much you as that one-cell you were at first, inside of your mother! Isn’t that cool?
171-have you heard the mitosis waltz?
172-No.
169- You got it. Have a cookie.
174- Thank you very much…
*bows*
175-lucky.
176- Aw. You want a cookie?
Here you go, you can have it…
Keep it!!!
171-Yes, that is cool!
170- electrons deserve their own children’s book. they [are] share[d], they get excited….
177-I’m not allowed to have cookies
um…is it possible for someone to be kicked off of MuseBlog?
181- yes*, why?
*Or at least banned.
182-Why would that happen?
ARGH YOU PEOPLE ARE MAKING ME DIZZY!!! MAth…. math…. math… that word ruins my whole summer….. I’ll talk about science instead. So, anyone heard of the mega volcano that caused an ice age? No? It’s very interesting…
A Supersized Volcano
Beginning in 1949, when Dutch geologist Rein van Bemmelen discovered massive deposits of volcanic rock along the perimeter of Lake Toba on the Indonesian island of Sumatra, scientists knew they were onto something big. The thousand-square-mile area around the lake, it appeared, was a gargantuan caldera once filled not with water but with steaming volcanic ash and pumice. As volcanologists pieced together evidence of the cataclysmic event that took place there 74,000 years ago, as well as two earlier eruptions, Toba seemed so immense it was deemed a “supervolcano.”
Why Toba Matters
What can a volcanic eruption that occurred almost 75,000 years ago teach us about today’s world of air pollution, global warming, and climate change? Heaps, says Dr. Drew Shindell, a climatologist at NASA’s Goddard Institute for Space Studies in New York. For starters, knowing what the massive upheaval of Indonesia’s Toba supervolcano did to the planet’s climate (it might have cooled global temperatures enough to kill vegetation for years on end and perhaps hasten an ice age) offers sobering insight into what pumping billions of tons of chemicals into the atmosphere as we’re now doing could result in. In this interview, Shindell shares his thoughts on Toba’s impact then and now.
Isn’t that just awesome? There could be some hidden gargantuan volcano just waiting to erupt. And when the population of humans is highest it will explode, and kill us all. But that’s a big IF. A huge one. I hope.
182- Flaming. Here’s the Stuff:

can we have a religions list anytime u can get 2 it, e~a? just wondering.
i’m Radical Atheist, as previously stated. unlike some people, *coughfridgeycoughcough* I don’t change my religion every thread.
16. FrigidSymphony | March 19th, 2007 at 6:41 am
10: Mohammed was pagan, as was everyone in the middle east. A bunch of sects. And you can’t draw a picture of him because that just gives the muslim radicals an excuse to be violent.
17. FrigidSymphony | March 19th, 2007 at 7:05 am
15: You’re an idiot. Asatru is a form of paganism.
18. ~~Red-tailed HAWK the swift~~ | March 19th, 2007 at 7:45 am
17- NAME-CALLING ALREADY?!!!!! THAT IS WHY I NEVER WENT TO THE LAST THREAD, BUT I WAS HOPING THIS ONE COULD BE DIFFERENT! Maybe not. *sigh* *sobs*
19. FrigidSymphony | March 19th, 2007 at 8:01 am
18: You’re an emotional wimp. Grow a backbone and contribute to the discussion.
20. Robert Coontz (Administrator) | March 19th, 2007 at 9:48 am
Sorry, FrigidSymphony. Insulting other MBers is crossing the line. You know better. I’m banning you from the blog for a week. Lurk as much as you like, but you won’t be able to post.
I don’t enjoy doing this, but things have been getting unMuserly and unMuselike around here, and it’s got to stop.
Oh wow! Did she ever return?
SCIENCE AND MATH???? THE DAY BEFORE THE LAST DAY OF SCHOOL??? *sob*
187- He. He. And yes, He did. a Week and a day Later. And then he left a few months ago.
What is happening here?!?!?
180- Thank you…
This thread is starting to sound like the Random Thread. Please keep the conversation on track.
191- Sorry…
Does anyone have a math problem?
192, 193-Please try to avoid double posting.
Sixteen minutes until Discovery touches down…
Over Yucatan, 750 miles to KSC…
Visual!
75 miles to go…
Touchdown, all is well.
Welcome home, Discovery.
Woot! *rejoices on behalf of Discovery*
194- It’s kind of ironic that you scold CTN for double posting, and then KaiYves posts 5 times in a row…
Hooray Discovery!
199-What ARE you talking about?
I feel like everyone os somehow managing to read the NASA website without dying of boredom. I find it boring, but your guyses summaries are good. I think I’m going to find every single space important date and time way after you guys do. But then I’ve got to lear to brave boring stuff if I’m ever going to be a grown-up.
203- He’s talking about the space shuttle Discovery, which has just returned to Earth. *celebrates*
204-returned from where?
205- The ISS. To fix a toilet/inspect a Japanese lab.
204-She, just so you know.
I’m so glad it’s home safe!
194- Well, I DIDN’T even post the two comments onthe same day!
The Discovery? I’ve missed alot of space-craft! I guess I was too absorded by Titan.
Hooray, Discovery!
About a topic long since been forgotten…
I doubt anyone here can find 1 situation in real life in which there is an infinite amount of something existent.
Of course… this brings up the question “what is real”.
Speaking of space travel, I’m not quite up to date.
By the way, do you think humans will ever send things into space? It would be really cool!
210- define “things”.
211:
uh…
stuff
you know, debris, “space ships”, anything…
Maybe some day, humans will walk on… the moon!
Maybe this is too far fetched.
No, you can’t have infinity. It’s really just a concept, not a physical object. Wait… Thoughts! There are an infinite amount of thoughts! And parallel universes!
I doubt that any of this, like seeing the side of the moon that never points at earth, or forming a “space station ” will ever exit the realms of science fiction into reality.
by the way, do you think that the world will end in 48 years?
you know, y2K?
2000 is a while from now, but I’ve just been wondering…
Parallel universes have yet to be proven of their existence, and thoughts are intangible.
anyways, both, while not “finite” are not infinite.
there are insurmountably many of both, but if time stopped, you could count them all up with the right technology.
but that probably wont be invented until the last year in history…
1999.
Maybe even Dec. 29 of it.
214- 1952?
Would “Science and Math, Including Space” be a good place to show my idea of how to engeneer HPBs, or should I go somewhere else for it?
In my time zone, its getting late.
‘night.
216:
yeah,
you got a problem with that?
218- Talk to Paul Baker. He lives in the past, too.
(215, 216, 218) A genuine inhabitant of 1952, eh? That’s exciting. We can tell you a few things about the future and maybe give you a little investment advice. You’ve got some surprises ahead! For one, you’re wrong about the end of the world. The year 1999 will come and go, and it will still be here. Ditto 2000, and at least seven years after that. There are a few places you’ll want to stay away from at certain times, but nothing global.
As for money — any ideas, MBers?
220-What about money?
Well, someone in 1952 should be able to make loads of money on stocks and bets and things, with a little advice. I was just wondering what you would advise.
220- Microsoft hasn’t been founded yet… wait about 23 years, then put your money on them.
223-Oh, now everyone’s talking about MICROSOFT!
*freaks out*
Don’t invest in airlines, they keep going bankrupt.
Electronics is a major industry- never underestimate the will of the people to be lazy.
You’re best money making option might be as a science fiction writer– who gets it right. Then, in about 20 years whe everything comes true, you get loads of publicity and everyone buys the book.
214- Okay, be a science fiction writer and get everything right as zyviva said.
In 1957, the Russians will launch the first satellite, Sputnik.
In 1959, a probe will photograph the Farside of the moon. It is mostly barren, with no lava plains.
In 1961, the first person will fly in space, Yuri Gagarin.
In 1963, the first woman, Valentina Treshkova.
In 1969, people will walk on the moon.
Are the wealthiest science-fiction writers the ones who most accurately predict the future?
227- It depends on if they live to see what they predicted come true.
The wealthiest science fiction writers are the ones who sell the most books.
I suspect that the wealthiest science-fiction writer ever was L. Ron Hubbard, who founded a religion — which, if you built up a track record for accurate prophecy, I suppose you’d be in an excellent position to do.
Found a Religion? *Cackles Maniacally*
If you really want to make a bundle, put money on Berkshire Hathaway. You’ll be glad you did.
What is happening here? History?
At 02:00 on December 25th, 2005, the Cassini orbiter will release the Huygens probe.
At11:04 on January 14, 2006, the Huygens probe will land on Titan…
The results will be amazinf!!!!!

227-Or least accurate.
233, 234- How did THAT happen???
Oh well, space is wonderful!
Oh, hi, CTN! Long time no see! Email me more!
219:
I DON’T live in the past!
I’m only… wait, for safety purposes, I cant give my exact age…
So I am between 11 and 13 years old.
That’s too young to live in the past.
and it is 1952!
wait, computers were invented many years from now… how would I be on the inter – reli7tyR*U(TH%T^(&*YT%&)T(*Y#$*&FYH(I#$&FUWGE*$&ZZZZZT
219: who’s Paul Baker?
Our resident wung expert and Tudor musician.
239- he is paul baker.
I Think, GAPAs, that is the best way to describe him?
(241) I think that covers it, yes.
237- That is quite random for the space thread…
238- That is quite odd. Are you sure it is 1952?
I think perhaps Fforde Fan is spoofing the prevalent idea that the world will end in 2012 by pretending to believe in an End-of-the-World scenario that we already know not to be true.
244- ???
End of world scenario? Someone explain…
And tell Fforde Fan to beware of Global Warming…
245- Y2K. Everyone thought that all the computers in the world would crash when 2000 came, because they’d read only the last two digits, think it was suddenly 1900, and cause a paradox. It didn’t happen thanks to a bunch of hard-working computer programmers who fixed the bug that would have caused the crash.
246- And May I ask, what was the problem with that?
All the pre-millennial doomsday talk inspired me to write an end-of-the-world article for Muse.
246- All the computers crashing would certainly result in a great deal of pandemonium, but the world wouldn’t end because of it.
249- You’re right- I suppose it would be more of an end-of-civilization scenario.
250- hardly that. how many people had Computers back then?
251- Probably not many, but how about in 1999?
How long do you think this war will last?
I hope we finally win against The Soviet Union.
The war in Korea, do you mean?
Everything ends up okay in 1990 or thereabouts, and you won’t have to worry about the USSR anymore. And you make it without anybody being blown up.
This is getting interesting…
But WHAT does this has to do with space???
I have a time travel question:
Which of the following four people are older? An adult, (say, Paul Baker) who lives in the past, a minor (Say, Brendan The Science Whiz/Fforde Ffan) who lives in the past, an adult in the present (Say, Robert), or a minor who lives in the present (Say me), and why?
An adult in the past, I think… (This is sort of Science…)
An adult in the past…
(maybe it is)
254: good!
254: I’m glad!
257/258– why?
(258) Most people who were adults in the past were younger then than they are now (assuming they’re still alive).
*Gets a headache from All the talking*

I figured out how to find the area of a circle in a way completely different than the current method.
It does not involve Pi at all, but instead uses a different arbitrary, and endless (I think) number…
1.5580204… … …
What should I name it, like how 3.1415926535… is called “Pi”,
and 1.6… is called “Phi”?
Oh, and by the way, I checked, it is not half of Pi, and when i refined it, it moved away from Phi.
What year does Paul Baker live in, I may still be older than him.
1.5580204!!!!!
264- do share the method.
I just realized that it is not quite as accurate as before, but it is about as accurate as piR2 using 3.14.
What you do is you get a circle and make a square inside so the four corners are touching the outline of the square.
There should be four semicircles left uncovered by the square.
Find the area of the square and multiply it by 1.5580204 (until I refine it…) and that is the area.
Anyone with too much time on their hands over the summer are welcome to join in helping.
266- although your number is not equal to pi/2, that is what you are trying to multiply it by. here’s my reasoning:
Definitions:
there is a circle with radius ‘r’.
the square that is in the circle has side length ‘s’.
r and s are both any real, positive number.
your mystery variable is ‘x’.
steps in my logic:
1. 2r is the diagonal of the square so r=s/root2
2. pi*r^2 is the area of the circle so I proceed to the following equation:
pi*r^2=x*s^2
3. since r=s/root2, the equation in step two can be changed to read:
pi*( s/root2)^2=x*s^2
to simplify that:
pi*(s^2)/2=x*s^2
4. divide both sides by s^2 and:
pi/2=x
I applaud you for trying to solve things differently, even if this time it came to naught. Does my logic make sense to you?
255-It doesn’t have to do with space.
267:
Not really, but I believe it is correct because most of it makes sense…
And technically, it didn’t come to naught. It is still its own method.
Pi/2 is its own number, and thus can be given its own name.
Oh, and how can you do the weird thing with the “z”?
269- what ‘z’?
270-The “Ê‘”, he means! Ê‘Ê‘Ê‘Ê‘Ê‘
??????????????????????????????
I am confused…
272:
about what?
271- oh…. *sheepsih grin*
its alt + 657 in word,but when on the blog all i get is æ, so i copied and pasted.
I just made honors!!!!!!!!
*pies myself out of happiness!*
*pies brendan with celbratory pie*
I got a five!
277 – On what?
277 (zyviva): Congratulations! I’m assuming that’s an AP score? Which subject?
279- calc ab
*hands 1,537,916,204 congratulatory pies to Ê‘yviva*
281- My thanks.
What is happening here?
It doesn’t seem that people are talking about space anymore.
Anyways, I made an Asronomy Blog website:
[Snip! Sorry, it’s still a personal website, no matter how otherwise harmless. –Admin.]
It’s rather harmless, so…
Okay, this is not a popular thread…
This is a very, very dead thread. A very dead thread, a very dead thread…Anyway. I just saw a post from back when I was bubblebabe46 that I’d post on the Space thread. So here I am, a little late.
Today – actually, just now – I realized how little about space I actually knew, when I couldn’t name a single space vehicle out there now but Challenger. And I’ve probably gotten the name wrong, because I just realized wasn’t that the one that blew up> I mean the one that went out in like the 80s, the one with the picture of the man and woman on it…the one mentioned in Space Station Seventh Grade. It was a space station, that’s what it was, and what is it called? Ugh. I’ll go try to look it up…
I found it. It was the Pioneer. Now, why did I think it was called the Challenger?
AHHHH!!!!! LIVE THREAD, LIVE!!!!!!!!! So, with that out of the way, does anyone else here think black holes are confusing? I mean, I know what they are-basically a small hole in the fabric of reality-but, that just makes my head spin.
Pretty much all I know about space is that the planets go Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto, and that Jupiter is the biggest. Actually, space scares me a little.
