[QUOTE=DesolateGrun;33866888]At school I'm on the debate team and this year we are debating if the us goggles should spend money on advancing the space exploration and or development. Its horrible to see 90% of the team strongly opposing it and calling it a huge waste of money on trying to leave earth. They laughed at SETI, Space platforms, asteroid mining, and a bunch of other plans. I feel there isn't enough teaching in schools aabout space, we should learn more about it rather than having a weeks lesson on it. I wish they were more educated as well as the country, on how beautiful and amazing space is and why we should take larger initiatives to expand from the earth into the stars, and not let our species eventually stagnate and die in the future.
Plus Carl Sagan is awesome
Sorry for grammar and spelling I'm on my phone[/QUOTE]
Use facts to blow the other team away.
[quote=Wikipedia]At 1997 prices, a relatively small metallic asteroid with a diameter of 1.6 km (0.99 mi) contains more than 20 trillion US dollars worth of industrial and precious metals.[/quote]
Talk about developing technologies too. A good example of a development that might make getting into space more economical would be Single Stage To Orbit (SSTO) spaceplanes, such as the [url=http://en.wikipedia.org/wiki/Skylon_%28spacecraft%29]Skylon[/url].
Speak clearly and passionately to your audience and victory will be assured. I wish I could have had debate topics like yours in school, ours were boring as shit.

[QUOTE=Collin665;33867174]Maybe if we weren't ~15.1 trillion dollars in debt with a stunted economy I wouldn't mind spending 40 to 400 billion dollars on a temporary 6-10 person colonization of mars, but not right now.[/QUOTE]
It kills me inside to think that a good $3-4 trillion of that was spent purely on killing people. Can you imagine the insane building projects, the infrastructure the US could have created with that? Can you imagine having a proper healthcare system like the rest of the world?
Unbelievable.
Keep in mind the other team will have facts, too.
So make sure to think like them and come up with ideas for their side, and then think of how you would work against those ideas.
If your debates are like real debates, you get a few weeks to prepare, which means they're preparing too.
And yes, I agree, our war on brown people, or for black liquid with high energy contents, or for parcels of sand and dirt, or whatever we've been at war for, has been pretty stupid.
Turnips thanks for the help, but I didn't do debate freshman year so right now I'm not the one speaking, mainly I'm researching and providing facts and statistics. I wish this was next years as I would be able to express my views. Though I do do my best to give them the good info as they no nothing about space at all
I don't understand people bitching on prices and expenses for space programs. No matter how much we spead on a rocket or mission up there, the military funding for a couple missiles and an attack helo is always more and gets no complaints.
Carl Sagan once said that now is the critical point in our history where we choose to either make an economical desicon to stay on earth forever, or we branch out wards into space forever changing the human race.
There are two types of sentient species, ones who are spacefaring and ones who aren't. The later will stagnate and die.
When Carl Sagan was alive our economy was quite a bit better.
In fact in 1980 our debt as a ratio to GDP was some of the lowest of the century.
And I do agree that our military budget is overinflated, but I also agree most people will say it isn't. Most people say we need it to protect our country and the like, or to protect other people's countries (Libya for example).

Why do we have to have our military presence around the world, why can't we focus on the problems within before spreading out too thinly. 700 B$ is more than china, russias, and the UK's military budgets combined
Becuz USA is world poleece.
Fuck yeah amurrca.
There's a reason we created countries and not just let eachother command its own village. Pooled resources give out better outcome. We should just create a unified pool of money with the chiefs of staff of each country serving as its government. (Disregarding power balance, which does have a solution, just a hard, long ).
a hard long what
I'm in the science thread right?
solution.
We're using exactly the textbooks I'd hoped for Quantum and GR. :D Griffiths' Intro to QM and Carroll's Spacetime and Geometry.
[editline]6th January 2012[/editline]
So excited. I've already started typing up notes for Griffiths' Intro to QM.
I feel I understand special relativity a lot better now, after learning the transformations, deriving the velocity addition formula, doing a coursework question involving a missile being fired from a moving spaceship perpendicular to the direction of travel etc.

Is there a limit of how big a planet can get?
Or will it ultimately turn into a star if it gets too big?
And does the same thing go with stars as well? Will a star "explode/implode" if it gets too big?
How would a planet turn into a star? A star is mainly made of hydrogen, planets (unless they're gas giants) aren't. If it were massive enough it might just collapse into a neutron 'star' or something similar, but it wouldn't just become a star.
I imagine you end up with quite a bit of hydrogen and helium if you were massive enough, simply as a result of the abundance of those elements
Was kinda referring to gas giants, probably should have included that, my bad :v:
[QUOTE=booster;34159190]Was kinda referring to gas giants, probably should have included that, my bad :v:[/QUOTE]
That's basically what happens. You get gas giants, brown dwarves ('failed' stars/really fucking big and hot gas giant), and then stars.

Hey guys not sure if this fits in the science or the maths thread but here goes.
If a tractor has 4 wheels, the front pair of wheels is smaller than the rear pair. Which pair of wheels will spin faster when the tractor is in motion?
They would both revolve at the same speed wouldn't they? Because theres a quiz that says the smaller wheels spin faster.

The smaller wheels would spin at a higher RPM, so if you measured the time it took a single point on the smaller wheel to return to its original position, it would be shorter than if you did the same with the larger wheel. They would both cover the same distance over the same amount of time though.

Their SPEED is exactly the same. Their [url=http://en.wikipedia.org/wiki/Angular_velocity]Angular Velocity[/url] is different.
No mention of the geodesic deviation equation on the wikipedia article for tidal forces? Wat is this
I wasn't looking forward to lab this semester, but it will actually be pretty neat I think. There's a big windowed area in the lab building with a pit that was originally for a Foucault pendulum but it wasn't big enough. Now they want some sort of impressive physics display there, so the whole class is collaborating on the conceptual design report for a spark chamber to be put in there, plus probably a single-gap working prototype.
Okay so I just heard that I gt an E in Chemistry, I genuinely believe this wasn't my fault. My class is full of fucking dicks who get sent out and make the teachers life hell, which leads to us learning nothing. Although, now I'm studying physics and in March I get the foundation Re-Sit, which means I can ONLY get a maximum mark of a C. But, my coursework will hopefully pull me to a B/A if I hit the high C's in the exam. Another thing, I have my resit on 1st of March and my physics on the 2nd. Is there anything I can do/watch which will pound this stuff into my head? As far as I can remember in my chemistry exam it was about atoms, conducting electricity, metal, and other shit, balancing equations wont be in my resit, as it's foundation.
This isn't what I'm worried about, the fact is I now have to revise for 2 exams, whilst I haven't had lessons for Chemistry since before Christmas. In 41 days. Is there ANYTHING I can do which will make me hit C's on both of them? I love physics, I swear to God I think I've nailed the C in that, but I wanna be sure, is there mock exams online?

there may be specimen papers and past papers online - it depends on your exam board and specification.
find the syllabus as well - treat it as a hit list of things that you need to revise.
