Greetings, Im 16 years old, a sophmore in high school. Not much mathematical background yet, although I am interested in the subject and Im willing to learn....

There's a reference to a Wilczek article in message #126 titled QCD and Natural Philosophy. In addition to that, here is an article he wrote in Physics Today a...
There is a followup to this question in this month's issue of Physics World. Now, it is the result of a readers poll on the greatest equations ever. See if it...
When Zapper told me about his poll of the most underrated physicists of all time, I was amazed to see that Roger Penrose's name even made an appearance. So,...

... Thanks Zapper. Is mass conserved in modern physics? In chemistry, conservation of mass is taken to be true. But with E=mc^2, it seems that energy is the ...
Hi Igor, ... As you stated, mass is not conserved, but rather energy (mass is a type of internal energy). For non-relativistic systems or low energy...
