except for the undergrad students you have to TA :x

lol. what if your tire blew. instant death :x

The book is readily available at pretty much any bookstore. I'll paraphrase his explanation later this evening. No, because any measurements you take will be measuring light's speed relative to you: 3.0xE8 m/s always. Its a funny phenomenon, and quite counter-intuitive.

for a really good explanation in terms for a general reader I recommend brian greene's book "The Elegant Universe". He gives a good, readable explanation of special and general relativity, along with a moderatly understandable explanation of quantum theory, etc. I say moderately because its harder to visualize, it takes longer to understand the concept. I think one of the best ways used to explain it is the bouncing mirrors analogy. try here: http://physics.miningco.com/cs/generalrelativit1/a/110703_4.htm Basically it all hinges on the speed of light being a constant in every frame. No matter how fast you're moving, light is always moving at c relative to you. This is counterintuitive, because you would think that as you move away from something at near the speed of light, it would appear to be moving slow, because the photons take longer to "catch up" to you. According to a person at rest [relative to you], they do take longer. According to you, they don't.

I've had Deja-vu like tha tbefore too, where I swore I had been to a place in a dream. I always figured that its my mind playing tricks somehow. Until I predict the lottery numbers in my sleep its just some sort of deja-vu.

Next time you may make it across even faster.... .....in a body bag on an airplane...

mwahahahahaha :worship:BLIKE

lol, that makes about as much sense as the original

hrrm... This morning the server was down a bit so that COULD have been the cause of your problem. The other possible cause is that you mispelled scienceforums.net, or typed scienceforums.com or something.. Regarding the email thing: It should work, I'll look into it. Maybe the mailserver was down yesterday, but I'm pretty sure it works. Double check that you have the option selected (in your user CP) and I'll double check that it actually works Regarding the automatic login thing: That feature only works if you don't delete your cookies. You might have IE set so that it automatically clears cookies every night, or something of the sort. Double check on that. Let me know how it goes

Well, obviously some dreams bend the boundaries of physics. My recurring flight dream (doesn't everyone have one?) is obviously breaking some rules. It is interesting though when you think about things following physical laws in dreams. Of course, this should probably be expected, because we live in a world governed by natural laws. Whats interesting is that someties the brain (at least mine) does actually seem to be logically working through things in dreams. I remember one time last semester I woke up in the middle of the night knowing that I missed a problem on my calculus exam, and also knowing why I missed it. It was one of those problems where you know you're doing something wrong while you're working it, but you just can't figure out what. I remember later in the day I was thinking about it and I couldn't figure it out. It was quite strange. So from personal experience, I'd say the brain does consider physical laws while in the dream states. When you say "calculating hair blowing in the wind" it brings to mind a computer crunching raw numbers to calculate the position of each portion of the hair. I don't think this is the way the brain works. When you catch a baseball you are not calculating the trajectory, derivatives, and slopes in your head. Most people can still catch a ball with reasonable acccuracy. I can sit here and picture long hair blowing in the wind, but I'm not "calculating" anything.

Hey there! We're glad to have you! And yes, you can post anything you want in the general discussion forum Of course! You're welcome to post any and all questions relating to science you have. If you know something about what someone else is asking, feel free to answer. The only rule about posting questions is that we're not doing your homework Don't get me wrong, you can post a question you have about homework, but you should try and exhaust other options first Post a poll is exactly what it says: It allows you to post a poll, and people can vote on the options. Changing your style changes the way the forum looks. Currently, there are three styles, but the one that has the most features is "Orbitz". You can play around and see which one oyu like, though the other two aren't really "complete" stylesets. You'll be missing out on a lot if you don't use orbitz. Anyhow, welcome!

probably next to nothing, considering only a few neutrons are released / minute. still, the kid is fusing atoms in his room :/

Did you tell anyone? If so whhy?!?!?

welcome!!!

or if we had a much faster speed. its all relative.

YT, is the book "Time Travel in Einstein's Universe" or just Einstein's Universe?

Why can some people move their ears while others can't? Why can some people roll their tounge or contort it certain ways? Also, why can I lift up the left corner of my mouth (while keeping the right side down) but not the other way around? Why why why!

What are duty cycles and feelers? (sorry, i have no electrical background!) I'm not sure how much electricity is in a lightning bolt, but here in florida we get thousands of strikes per day! A quick search of google revealed that it is likely between 10 and 120 million volts. I don't know much about volts, watts, amps, etc....but that seems like an awful lot!

I believe sayo is a laser expert i personally have no idea :/

We are leet. While optimizing the database: Optimization Results Total Space Saved: 92.875 Kb You have run this script: 13 times 1337 Kb saved since its first execution! | | | | | | | V Just think, you'll never get those 3 seconds of your life back. mwahahaha.

Have you ever seen those scientists that cause lightning to strike by launching model rockets at specified times? Why can't we gather energy from that somehow?

"This is the dream - we're going to get this sensational footage of the giant squid trying to do obscene things with the camera." In an article that describes male giant squids as "randy", the BBC is reporting on Dr. Steve O'Shea's plans for catching a giant squid on film for the first time. "The freezer bag at home - to my wife's disgust - is actually full of giant squid gonad samples. We're going to grind all of this up, and we're going to have this puree coming out from the camera, squirting into the water. "Hopefully the male giant squid, absolutely driven into a frenzy, is going to come up and try to mate with the camera. Steve believes that the giant squid migrate annually to an area in New Zealand to mate. Like their more common cousin the scuttle-fish, the female giant squid are believed to secrete a sexual scent that drives the males into a "frenzy" I'm not sure which part of the article is more humorous, its graphic description of the mating process, or Steve's "dream". "The two of them mount beak to beak, so you've got arms and tentacles flying everywhere," Dr O'Shea said. "The male is co-ordinating this enormous penis, and he's implanting spermadaphores into the female's arms. He uses the penis like a plunger or a huge hypodermic needle, and he's physically stabbing the female's arms." You can find the full BBC article here.
