I know the basics (H to He...to Fe), but I've never seen an explanation showing the origin of every single element, or anything with an atomic # beyond iron.

if energy is equal to matter times the speed of light squared,doesnt that mean you have to get the matter to travel faster than the speed of light to get the results.how fast is the speed of light squared?can light go that fast?

I asked a question this morning trying to learn more about evolution so I could argue more effectively and I used the word "macroevolution." Only after irritating sever people and getting told off twice did I learn that the word macroevolution is a part of the creationist propaganda machine. I've never bothered to learn about this 2nd law of thermodynamics thing because it's my understanding that it has no baring on evolution. But does it even exist at all? It sounds more like geology than biology, but what do I know?

You’ll see them hit the floor at about the same time.
But if you drop them off the top of a high ladder, you’ll see the golf ball hit first. What is your explanation?

Say you have a rope...on one end a force of 50 N is applied, on the other a force of 20 N. I know that this will cause acceleration in the direction of the 50 N force...but what is the tension in the rope??
