and lined them up, would the line be able to make it to Alpha Centauri, and if so, how much farther would the line be? I read in "Mad about Modern Physics" if you lined up the atoms in a grain of sand end to end it would be 30 times the distance from Earth to the Moon. So, naturally, this question came to mind.

Alright I have an assignment for school where I gotta get any biology article and write a summary on it. I can't find any articles that I can summarize. Can anyone send me a link for an article I can actually summarize? Genetics or DNA would be the subject of choice, but any other subject in Biology would work.

How would you blow it up more without adding any more air? You can't add anything like helium, water, etc. and it's already sealed. I think it has something to do with heating and cooling or something...
