What if all particles were not moving but standing still. What would it be like then? If it was so on the quantum level would that affect the way we experience the world?

For something to travel at any speed it has to exist. Light does not exist as a physical entity. It is the stimulation of Primary Force. Light does not travel. Think of it this way. Suppose you had a steel bar of x feet. Hit the end with a hammer. Then ask how long does it take for...

how it is calculated. what is the ranking of physics journals in 2003

Physics Project :D okays, for physics I've got to devise a contraption which will protect a raw egg from ing while dropping 3 stories. the devices must fit through a 1sqr foot rectangle, it does not have any maximum height, it cannot use packaging material or food/peanut butter/jello/gell...

these questions are challange questions from our teacher (MIT grad) who gave us these knowing that they were a bit out of reach for us as we are a beginning intro physics class(HS). we haven't but scratched the surface on these topics. so we're trying to find/acquire at least a basic, rough...

Hello all, I was wondering what advance in physics had the most impact in history and why. Personally, it's tempting to say E=MC^2, which said it was possible to give us the bomb, but it seems that that is too recent to really calculate the effects. Perhaps Newton's laws of motion? Or...

Where to find those? I thought it was on the ISI Journal Citation Report website, but I have been going around in circles without finding anything.. How about citation finder?

I was thinking.when we mass produce electricity,we send out high amounts of negative magnetic fields.whats the possibility that when offsetting the planets natural balance of negative electromagnetism.the planets positive side would be over powered by the increase of negativity.do you think this...

( I'm not making a poll of this. It no opinion.) But a simple question, where would you be weighting the most? A - On the equator B - On the North pole because you are closest to the centre of the Earth C - On the North pole because there is no centrigufal force of the spinning Earth...

A friend of mine, female, 20 years old, living kind of a stressed life, wakes up at 7:00 AM had some breating problems in the last few weeks. In that time she noticed that the pain gets really really more between 12:00 AM and 3:00 AM, sometimes she would be asleep in that time, sometimes not...
