A very interesting documentary on the great scientist and mathematician, about his struggles to reconcile scientific truth with his theism. His struggle is not unlike that of many modern scientists who try to fiit science with religion.

In my opinion Hawking does not deserve to be considered as one of the all time greats in theoretical physics. He contributed a lot to the theory about black holes, but other than that he's a mere popularizer of science. The fact that he looks like some extraterrestrial in his wheelchair probably helped making him famous.
I can think of a couple of others that deserve more credit... like Niels Bohr, Erwin Schrödinger, James Clerk Maxwell etc...

Newton was not merely a physicist; he was history's greatest polymath. He created integral calculus, co-created differential calculus with Leibniz, discovered the principles of light refraction, the laws of motion, the law of gravity, created his theory of light as particles that can function as waves, which is accepted to this day, etc. I don't think that there has ever been a person for whom the word "genius" applies more. Even Einstein regarded Newton as the greatest genius ever.

It is truly amazing how religious Newton was. He truly wanted for there to be a God, and he dedicated to proving His hand as the Creator of the Universe more time than he did to his mathematical and scientific pursuits. He refused to believe that it could have all have sprung from nothingness.

When I was in school many, many years ago and a fullblown nerd, I took this test just for kicks and it was famous for being incredibly hard.
One of the questions in it was about/based on Newton's laws of motion - the 3 laws showing the relationship between distance, time, velocity and acceleration
v = u + at
s = ut + 1/2 at2 and
v2 = u2 + 2as
The question was this - a man goes out to hunt, spots a bear and takes a shot at it. He misses, but pisses off the bear who starts chasing him. The man's gun gets jammed, so he runs, with the bear chasing him. He runs up a hill, which has a vertical ledge (so it's a right angle triangle shaped hill) and he goes all the way to the edge of the cliff and ducks when the bear jumps for him.
The bear goes over the edge and falls (and dies). They give you all the variables - the dimensions of the hill (both the height and the length of the hypotenuse), the initial velocity of the bear as it goes over the edge, it's final velocity when it hits the ground and the time taken for it's fall.
Then they ask you to find the colour of the bear.
How would you solve that? I'll give you the solution after a couple of guesses if you don't get it. Bear in mind that ALL the variables in the above 3 equations are already given ;)

With the velocity at which the bear fell and the time it took to hit the ground you should be able to determine it's mass and hence it's color. It is either going to be a brown bear (black) grizzly (brown) or polar (white).

I thought this at first but it seems too simple. Well, in truth, it has to be the answer doesn't it? Unless you are given a chart with the bears varying masses and corresponding species. Yeah, it has to be any color. Pretty interesting.

Nope. The mass of the bear is not given and doesn't have a bearing on the answer - assume it's an average sized bear. Keep the guesses coming.

Not at all. It's a serious question and you'll see the solution when I post it soon. I want to see SMM's answer.

No charts and again, assume an average sized bear.
This can be solved by any high school student who knows those 3 laws, which they all do. It's about how you arrive at the solution using those equations - just requires some out of the box thinking ;)
-
Again, the bear falls down a vertical cliff. You are given all the variables in the equations - it's initial velocity, final velocity, time taken for the fall, height of the cliff and even the slope (hypotenuse).
I've already given away the biggest hint.

I've heard the one about the north pole so I'll just take a stab in the dark and say a polar bear. Please tell though I'm intrigued!

It's not about simply guessing the right answer. The question is, how do you arrive at the solution? All the data you need has been given, including the equations (you only need 1 or 2 of them) - you don't even need the specific values of the velocities or time or distance. And there are no tricks to the answer.
You need to use logic, not guess. And I'll post the answer once SMM and a couple of others have replied.
Already given it away, in a way.

Just a wild guess but could it be that you have to adjust the gravity constant to make sense out of the equation with all the other variables given? So lets say you end up using the gravity constant of the north pole, it would have to be a polar bear.

Brilliant! And yes, that's how you solve it 8)
Most people assume g, the acceleration due to gravity to be 9.8m/s2 but in this problem, you shouldn't, since all the variables of the equation are given (which is the biggest clue - it means you are asked to calculate g, rather than assume it like you always do).
Earth's rotation causes a slight flattening at the poles and for it to bulge at the equator, so g's value varies between 9.78m/s2 at the equator to 9.83m/s2 at the poles
http://en.wikipedia.org/wiki/Gravity_of_Earth
Depending on the answer, the bear will therefore either be brown or white (no racist).
I almost gave it away by saying all the variables in the equations are given, but it made no sense in the test where that vital piece of info wasn't pointed out specifically, since it was a 10 mark question (out of 100) and everyone of us who took it thought it would require a fair bit of calculation / mathematics to figure it out, lol. Nobody got it right in the end and people groaned when they gave us the solution ;D
Pat yourself in the back for figuring it out 8)

But the Nasser option is the correct one here, obviously.

No, sorry. I took that test when I was around 12/13, so don't remember the specific values. It was the hardest "easy" question in the test, which is why I remember it. The rest of the stuff was more straightforward and about standard calculations / method of solving.
You can always work it backwards by assigning the values - shouldn't take more than 3-5 mins.
As you can imagine, if you simply present the values and pose the question, just about everyone gets so focused on the equations/calculations part that they fail to notice that g shouldn't be assumed. So make sure you word it accordingly, to throw your teacher off course, lol.
And if you want to be more deceiving, you could simply post the length of the base and hypotenuse of the hill, so the height (distance of the fall) of the hill isn't given - most people would work that out first, since it's the first thing they need to do and then get stuck :D

How do you think Tesla compares with Newton? You think they were equally gifted or was Newton in a league of his own?
BTW, this is extremely nerdy, but what the hell - I remember reading this poem
Nature, and nature's laws lay hidden at night
God said, "Let Newton be" and everything was light
Someone later added the next 2 lines
But that wasn't all. The Devil howling, "Ho!
Let Einstein be" restored the status quo

They are not really comparable. Newton was a theoretician and a polymath; Tesla was an inventor primarilly. And of course Newton was superior both in terms of genius as well as contributions to Mankind.

While we're being nerds... I think it was Pope.
Also heard that Newton worked out his law of gravitation m * m/ d2 as a young man during a rural holiday, avoiding a London plague outbreak, but he didn't have his books with him and used the wrong dimensions for the Earth, so he miscalculated its mass. "Close but no cigar" he figured and shoved his calculations into a drawer, where they remained for about 40 years until Hubble and a couple other famous dudes I can't remember were working along very similar lines (over a pint, as I heard it). They came to see Newton about it and he told them that he did it already, a long time ago, and it didn't really work. So he brought the calculations out of the drawer and I guess someone kindly pointed out that he had used the wrong number for the diameter of the Earth.
-
It's basically this problem, right?
(http://i53.tinypic.com/xppkwk.jpg)
a is the acceleration that the gravity exercises upon the bear, s is spatum/distance from top of the cliff to bottom. v0 is initial velocity and v is end velocity. t is the time it takes the bear to reach the ground when he jumps off the cliff. As you said... every of these informations is already available.
From physics, we know that
s = v0*t+(g*t^2)/2
-> g = (2*s-2v0*t)/(t^2)
Now that we know what the gravitational acceleration is, we can also find out the location.
North Pole g: 9.832 m/s^2
Equatorial g: 9.780 m/s^2
Most bears live in the zone between north pole and equator, that means, in that case, the g is somewhere in between the north pole g and the equatorial g, but only the polar bear lives at the north pole. So depending on the input values we either get g=9.832 or something in between 9.780-9.832. I guess with given values, it's much closer to 9.832, which ultimately makes the bear white, otherwise it'd be hard to distinguish between the brown, grizzly and the black bear, because all of them live in the vicinity of similar latitudes.
**I see you already figured this one out
Concerning Newton and Tesla: Being a polymath back then was outstanding, but by today's standards, it would be impossible. Nowadays, everything's so specialized, you can't be a biomed expert, a top mathematician plus a renowned painter at the same time. Tesla was, in a way, a polymath, too. He was very good at math and physics, had some fantastic insights into electricity, knew many languages (Serbo-Croatian, Latin, Italian, French, German, and English) and was very much into literature, be it goethe or twain (the latter even being a very good friend of his). But what really sets Tesla apart, in my opinion, is that he was first and foremost an engineer, meaning someone who could put his ideas into reality. Many don't see how hard it is to make reality out of theory. Sure, Newton was great, but it was all theory, and it's good. But being a theoretical genius plus proving your genius with real life applications, that to this day remain used, is something that very few scientists throughout history can claim. For me, Tesla is the biggest genius. But everyone is entitled to their own opinion.

Interesting, never heard that before. I need to brush up on these giants, 'cause it's been ages since I looked into this kinda stuff.
And I wonder what kind of eccentricities and craziness Newton was known for. From what I've seen, the greater the mind, the more the eccentricities and perversions - very thin line between genius and madness that often gets blurred and crossed. Would be interesting to see read about them, lol.

My thoughts exactly, which is why I asked that question. I agree with what SMM says regarding Newton's accomplishments, but people underestimate the amount of thought, frustration and work that goes into coming up with real world applications of theoretical models, which is ridiculously difficult.
I suppose it's apples vs oranges in a way. Who knows, if Tesla had dedicated his life to pure theory, he may have been on par with Newton or at least come close. We need both kinds of people to progress.
