Also remember the size of bacteria and the cost benefits of seeing with vision. Many of the bacteria's inputs of the outside environement are through channels and receptors that lead to signal transduction cascades. That is to say that some outside stimulus can bind on a transmembrane protein...
Look around and imagine how we remain.
We do not radiate all the energy we consume, so if we radiate like a 100 Watt light bulb we actually require a higher wattage since the human body is a very very ordered thing indeed. Just look at your eye ball in the mirror and try to imagine all the...
I am trying to get from one 2D coordinate system to another 2D coordinate system. I found 2 corresponding points and each system. I did the following:
[a1 a2 ] * [ x1,y1 ] = [u1,v1]
[a3 a4] [ x2,y2] [u2,v2]
or A*x = u
if I use MATLAB to...
I decided to numerically calculated pi using MATLAb and running a for loop. When I make the steps too small I get absurd quantities for pi. Here see for yourself. When I make the interval higher then about 1e10 i get errors, but 1e6 works ok. Why would this be? Thanks

I've yet to see something that does not fall under the category of either genetics ("nature") or environment (" nurture "). All the suggestions fall into these including stochastic fluctuations, which would be environment.
One more thing concerning the difference between 'prehistoric' or 'pre-footware' man and today's man (post-footware.) Hard surfaces can be the bane of our bones since these surfaces don't absorb much of the impact like dirt or grassy areas did for pre-footware man.
The notion of land being...
I agree with you when you say there is more variability when we use medical applications to aid people with diseases that cannot be supported without them. Who knows what selection criteria may be called upon by our environment in the future.
However, understand that 'natural' selection...
I actually think humans are evolving to be more susceptible to diseases of most kinds for the following reason:
Medical improvements allow us to treat those with diseases that should be fatal into diseases that are not fatal. For example diabetes type I , we have provided treatments to this...
Ah I see, I just integrate sqrt(1-x^2) from 0 to R. That's a tough integral though for a guy who hasn't done much calculus in 3 years, I was lazy and used mathematica to obtain the solution. Makes me feel like I would be useless in a deserted island. Thanks for the help.
Usually a vaccine is composed of benign portions and/or quantities of the actual pathogens such as viruses or bacteria. Your immune system will be able to recognize the pathogen based on its previous exposure to the vaccine. Sometimes multiple doses of the vaccine are required over several...
Imagine viewing a hemisphere normal to the equator such that it looks like a circile with the full radius of the hemisphere. Now randomly section or cut the hemisphere in a manner a tomato is sliced. If we only consider the portion of the hemisphere that contains the pole we should be...
That's kind of what I found as well when I searched for this list. I am currently doing a school by school search. Just posted in case somebody here might be helpful. Thanks though.
