My hat definitely goes off to Dr. Marshall who deliberately infected himself with H. pylori during his sutides. "Dr Marshall proved that H. pylori caused gastic inflammation by deliberately infecting himself with the bacterium. The Nobel citation praises the doctors for their tenacity, and willingness to challenge prevailing dogmas. "

That's another good discussion, but I don't think that's where the original poster intended to go with this thread.

That's where I draw the line. Somebody gonna get a hurt.

Swanson I just noticed that. We'll get it back up ASAP. If you guys notice anything else just let us know. We're working on getting the main navigation menu sidebar back up, as well as rearranging the "Latest Forum Topics" setup back to the way it used to be.

rofl. and film it.

Gorillas have been seen for the first time using simple tools to perform tasks in the wild, researchers say. Scientists observed gorillas in a remote Congolese forest using sticks to test the depth of muddy water and to cross swampy areas. Wild chimps and orangutans also use tools, suggesting that the origins of tool use may predate the evolutionary split between apes and humans. You can find the full BBC article here.

It's now 175mph sustained with gusts of 215!! Unheard of in the Gulf.

Contrary to the popular notion, their isn't much of a powertrip to being a moderator. It gets old after about a day. Then the monotony of dealing with people like you sets in. And Newtonian, no one makes you come back every day. Just leave.

Yes, neurosurgery is a 7 year residency program. However, remember that you also must do a 1 year general surgery internship. The minimum residency in the US for a specialty is 3 years, not 2. If you're counting from college is 4 years of college, 4 years of medical school, 1 year of internship, 7 years of residency. You have to have your bachelors degree. By far the most represented major in medical school is biology or chemistry. Culture is good, but you don't need a degree in art to be cultured. You need your four-year bachelors to matriculate at a US medical school. I'd say 3.5 is a good place to be. It depends on your MCAT score though. I once thought about neurosurgery. But it's a hard lifestyle. You can pretty much plan on not being married, except maybe to the hospital. Your malpractice premiums will be over 100,000 yearly, and you'll be sued several more times than the average physician. You can also plan on not having a life outside of medicine really, especially during your residency years (all 7 of them). You also must remember that during residency, you are earning about 40k a year, which is dirt cheap for the amount of sweat, blood, and tears you'll be pouring into your profession. You'll probably also be anywhere between 100,000 and 200,000 in debt from medical school. So you'll be living in an apartment driving a tiny economy car. Well, you'll be renting an apartment, you might not occupy it most of the time. If you do find a woman who will put up with you, you probably won't see your kids much. There's a joke in medicine that goes something like "How do you hide a dollar from a neurosurgeon? You give it to his kids." In addition to the lifestyle issues, you also have to pretty much rock your medical school boards.

Doctors wouldn't dismiss it automatically if it actually did something to help. I'm closing this.

I know I know, more questions. But I thought of this: Assume two clocks are ticking at different rates due to general relativity. Let's say they are in a direct line of sight. Over a period of 1000 years, one clock accumulates 1 extra minute. Both clocks are brought together, one is a minute fast. Shouldn't the one that's a minute ahead see a different position of the sun? But if they're brought together won't they see the sun in the same position?

Everyone should read this thread!

You probably won't find a comprehensive inexpensive book unless you buy one used. I recommend Campbell's BIOLOGY. I used that for Bio 1&2 in college and found it very well written. Here's a link to it's page: http://www.aw-bc.com/campbell/

That's my experience as well. At my university (USF) I don't think I had any science professors that weren't PhDs. I had a couple of T.A.s who were finishing up their PhD. They pushed their PhD progrma hard. I don't think I ever met any M.S. students in my time there.

Clearly the king of swing, Pete Sampras. I like Roddick's server and cross court forehand, but he's just not consistent enough to be considered really good. I hate roger federer. I don't know why. Probably because of his haircut.

Think about what force the incline is exerting on the block. There's a specific name for it. As DQW mentioned, its assumed there is no friction ("smooth surface").

I liked the first one. The only value in the second one was the eye-candy, and the third one isn't even worth a rent.

You did everything right, everyone was just afk. Certain times of the day the chat is really busy. Other times (usually late at night for the UK, early night for the US) it's really slow in there. Just check in periodically.

good point

Any suggestions on the name?

What do you mean "is saying vulgarities totally, completely bad?" It's bad because society deems those words rude or inappropriate, not because there's something intrinsically wrong with the words themselves. It would be interesting to see in two-hundred years how things have changed. Words we consider vulgar now may become the norm, and new ones will replace them. I wonder if all societies have cursewords.

Should we reinstall openscience?

I think this may have been discussed before, but is anyone interested in adding some basic science articles on here? I'm thinking anything from short reviews of topics to extended discussions. Would anyone be interested in contributing?

Thanks, that was the answer I was looking for. Does this imply that the events are truely separate for one observer and simultaneous for another? Or is it just tricks of light? Because what we perceive as our present experience is really determined by how fast light reaches us. So perhaps the lightbulbs are truely simultaneous, but because of the constancy of the speed of light, it only appears that they light up at different times? For instance, imagine I am viewing two lightbulbs in a mirror. One mirror is directly reflecting a light bulb. The other mirror beams the image to the moon onto another mirror, which then reflects it back to earth and off another mirror into my eye. They are set up so I can't visually determine which mirror is which by looking at the lightbulbs in them. The lights are both turned on simultaneously. However, in the mirror one bulb lights up faster than the other one (as the light has to travel to the moon and back). However, the true reality is that they are simultaneous. Is relativity just playing tricks with light similiar to the setup I have descibed? And finally, if there were a way for me to relay information to another observer instantaneously, could I tell someone the future?

For awhile I've felt I understood the basic principles of special relativity, but now that someone is prodding me with all sorts of hypotheticals I find that I really don't understand it all that well. Does special relativity imply that there are multiple "present realities" in the universe? In other words, can two people in two different inertial frames ever agree on what the exact present is? Is there a freeze-frame snapshot of the universe on which all observers would agree? Also, why do physicists use the term "time frame"? It seems deceptive, because although two observers may be in a different "time frame" they can still interact with one another. This implies that they are both experiencing a common present reality, correct? However, it seems to me at some point the present experiences of two people in two different inertial frames cannot match up entirely, or they'd experience time in the exact same way.
