Question by ραλπθ: Do you really need to know physics as a computer science major?
Some universities require three calculus based physics and I’m desperately trying to get out of it. UC’s such as UCLA and UC San Diego, gladly berkeley doesn’t so I can still apply there and other UC’s. I’ve taken AP Physics before and the subjects gets really hard after awhile.

What are the pros and cons of not taking physics and just go for the chemistry series? I feel like I have a better chance of getting an ‘A’ in chemistry and be able to maintain a good gpa for berkeley.
i like math and i plan to make up to differential equations. i just dont want to take it same time with calculus based physics. its going to be hard.

Answer by cabbage
you don’t need physics at all, but there’s lots of advanced and different kinds of math in physics. especially calculus based physics, and the broader your knowledge in math is, the better you’ll be as a computer scientist.

Question by None N: Is there really a secret chamber under the sphinx?
If so, why hasn’t the Egyptian government allowed and excavation, and will they ever?

Best answer:

Answer by loryntoo
They’ve looked for such a chamber, but haven’t found one yet. It’s far more likely that such a chamber would be under the ruined temples next to the sphinx anyway.

Have you seen the stuff about water erosion on the sphinx? Have you noticed the depression that still exists around the sphinx?
Seems to me that there was a pool around the sphinx at one time, probably in the same time period as those temples.

What do you think? Answer below!

Question by Koon-dog: Who really thinks the world will end in 2012?
It says in the bible that no man will know when the world is going to end, and when God comes it will be in the blink of an eye. So who really believes all that stuff about 2012?

Best answer:

Answer by Tayy<3
I dont. I think everything boils down to science and just because the mayans think the world will end in 2012 doesnt mean it will. Every old society had an end of the world date. there was one in 2006. The 2012 thing is just really publicized and since it hasnt happened yet, people think it will. That being say, PARTY AT MY HOUSE THE DAY AFTER!

Question by Ben: Due to laws of Physics is it impossible to “really” die?
If atoms cannot be created or destroyed,time is without begining or end,and energy can only be converted from one form to another but not lost.Then that means the whole universe and everything in it is like a giant lego set that keeps re arranging it’s self in different configurations?(all we are is a very complex lego set of atoms,keep altering the configuration and eventually you’ll get back to the original form).

If I had to choose I’d beleive this more than any of that heaven and hell stuff,or jesus fed 5000 with 2 fish and a loaf of bread,or Noah’s ark……..WTF.

Science has an expanation for everything!
Surley this also means that anything by the laws of physics that can happen will happen eventually and has happened countless times in the past.(that means everything from really horrible suffering to really nice experiances).

Best answer:

Answer by Randy P
Atoms are formed and destroyed all the time inside stars and inside particle accelerators. Atoms are made of protons, electrons and neutrons and we are always splitting those away from atoms or putting them together. Not only that, but in various high-energy processes those particles themselves are converted to energy, or constructed from energy.

So you have a misconception right from the start.

However, for most normal processes on earth, atoms are not broken up or constructed from particles. Living organisms when they “eat” are taking in atoms and rearranging them. In fact, they’re taking in atoms assembled into molecules (water for instance) and usually keeping those molecules together.

So for life here on earth you’re correct. There is a tiny bit of new matter coming in from space and going out to space, but for the most part life on earth is just rearranging the same atoms that have been here since the planet formed. We were dependent on processes in stars to give us those raw materials though. That’s one reason why our solar system is a lot newer than the universe around it. (Us: 4.5 billion years, Universe: 14 billion years).

I have no idea why that leads you to the conclusion in your last paragraph. If I pour some material into a beaker and then tell you it’s the same material in that beaker at time X, I don’t know why you’d conclude that everything conceivable has happened in that beaker in the meantime.
