This was in a maths textbook. An arrow approaches its mark, (where its supposed to hit) but as it approaches closer and closer, it will approach half the distance it was at some time ago away from the target, and so on and so on and so on.. So I am asking: Why does the arrow ever reach...

The Origin of Mind: Evolution of Brain, Cognition, and General Intelligence, 2005 Hello, I liked the book The Origin of Mind: Evolution of Brain, Cognition, and General Intelligence, by David C. Geary, 2005 because it not only discusses some of the latest research on human intelligence, but...

Does anybody know what is the transmittivity (light) of the brain, and how do you find that out? I am starting an experiment to image the inside of the mouse brain and most of the methods that I know of rely on external imaging techniques. Any reference for in vivo imaging of the brain...

So just how did the brain come into existence physically? ... To exploit an available resource perhaps? :wink: Which, I think is the whole point, why does anything evolve, if not to exploit the resources at hand? Why did our eyes elvolve, if not to exploit the available source of light? What...

Does larger brain size or brain/body wt. mean greater intelligence? Does a larger head mean more brain and hence greater intelligence?

Please someone help me with these brain teasers, Thanks! I have try to answer these problem, but I don't know whether they are right or wrong. PLEASE HELP! :cry: A hill is one mile from the bottom to the top and then one mile from the top to thebottom. A person drives a car from the bottom...

I hope this question doesn't sound too stupid but is the brain really gray? That is, is the brain tissue itself gray in appearance? If it is, why is it? If it is, is it the only human organ that is Gray?

Is it possible to measure the voltage, current, frequency of the electrical signals generated by human ‘Brain’? :smile:

I'm going to muscle my way in on the quiz action with the following quiz about the island of Great Britian (hopefully not too hard): 1) What is the name of the archetypal country gent, often depicted as wearing a waistcoat with the Union Jack emblazoned on it, used to represent England in...

On average, how many calories (approx.) does the brain need during the course of a day? Does more activity (thinking more than normal) cause an increased need for calories? How many calories are used while sleeping? Thanks, Jacob

I have a box when suspended from a cable in a vacuum is 4450N and is .608m wide (it's also a cube). W = 4450N = T1 (tension on the cable) V = 0.2248m^3 When I suspend it into a liquid, L/2 m from the surface, of density 944 kg/m^3, I want to know the buoyant force, the new tension of the...

I've got a U-tube filled with Mercury and water. If I add 11.2 cm of water to the left side, how much does the mercury rise on the right side? For simplicity's sake, D will stand for density, p0 for initial pressure, w = water, m = mercury, h = 11.2 cm for the water and d = the distance the...

What are the effects on the brain from hashish could anybody tell me? From the stage that one is stoned to the stage that the stoned feeling has decayed. And are there any long term effects from this substance? Does it really kill off brain cells for good? And why do you become so creative...

I saw this in an old, junior-level, classical mechanics textbook and haven't been able to figure it out. A particle undergoing simple harmonic motion has a velocity: \frac{dx_1}{dt} when the displacement is: x_1 and a velocity \frac{dx_2}{dt} when the displacement is...

show that a^13 is congruent to a (modulo 2730) if a is an integer such that a is not divisidble by 3, or such that a IS divisible by 9, then a^7 is congruent to a (mod 63) with these, could i just divide the mod numbers by the powers? that is what i am doing, but it seems like as though...

hey i have more problems that can really exercise the mind! here are 3. 1. prove if q is divisible by (r +s) then either q is divisible by r or q is divisible by s. 2. if d>0, (fd+ed) = d(f,e). proof. 3. a divisible by b => a^m divisible by b^m a,b,m are in Z+. i think i have...
