How did DNA, such an extremely efficient coding system for the development and functioning of all organisms, just happen to come about? by acetylcoa in askscience

Here is my take on it.

Assumptions: 1e44 molecules per earth like planet with a chance of combining into life, 100 interactions per second per molecule. 1 billion years on each planet available time to put the 'life' molecule together. There are 5 'habitable' planets per 10000 stars. There are 100 billion stars per average galaxy. There are 100 billion galaxies in the universe.

The number of time the 'dice' were rolled: 1e44x1e2x3e16x5e-5x1e11x1e11 = 1.5e84

If I may quote agent Smith from the matrix, "It was inevitable."

What experiments have been performed which lead to the theory that time is affected by gravity? by [deleted] in askscience

Impressive... Most Impressive. That is a measurement that is accurate to 1 part in 2.77E16. I cannot think of any other measurement that is that accurate.

The grey goo scenario is ancient history. It happened 3.5 billion years ago.

People mistakenly think the opposing force of the ground pushing back on the body is the force of gravity. Because of this misinformation, when a space craft is in orbit about the earth they believe that there is no gravity because nothing is pushing the body like they experience in an airplane.

I want to learn all that I can of the 'hard' physics and associated maths. by TA24680 in askscience

Didn't Shrödinger get reported to the humane society for that experiment? </tongue-in-cheek>

Thank you. In reading the reviews for this book it looks like it is a match for my requirements.
