My parents always told me that caffeine affects you less as a teen than as a toddler... I'm beginning to believe them. I'm 14, and I've noticed that a cup of soda doesnt make me as hyper and a cup of tea doesnt keep me up as long as when I was younger.

Looking in my garden it appears to be that the larger the spider is, the larger the gaps are in their webs. Is this because they cannot make webs with strands close to each other due to their size, or is it because they do not want to catch smaller prey and expend unnecessary energy?

epigenetic inheritance: fact or fiction?. So jean-baptiste lamarck was right all along. Epigenetic inheritance is how gene-regulatory information that is not expressed in DNA sequences is transmitted from one generation (of cells or organisms) to the next - that is (from the Greek prefix), 'in addition to' the genetic information encoded in the DNA. so can the memeories of our forefathers be encoded in our DNA? can this be extracted if we will clone humans?

Darwin's theory of evolution is flawed because it cannot explain why some biological functions heralded from natural selection, for example, the bacterial flagella. Intelligent design? what are the other explanations of the origin of life?

Cont: I was told the damage from such a head-on collision is equivalent to one of the cars, hitting a wall at 60mph. Why- if two cars are driving at 60mph, isn't that like one car driving at 120mph (if you pretend it's standing still)...so how could the damage be the same?

I'm not very good at math, but I remember that ever since the concept of irrational numbers and repeating fractions was presented to me, I was unable to comprehend it.

If irrational numbers go on forever- infinitely- then we can bring them out to billions and billions of digits without ever seeing them repeat or end rationally- but how do we know that this is the case? How can we be sure that pi doesn't end at the trillionth digit or something? or maybe it begins to repeat at some point. It just doesn't seem logical or scientific to say that "these numbers go on forever" without having any actual PROOF of this.
