Large Hadron Collider

Yes... but have they ever occurred at such mass levels? I would guess that the probabilities of that become incredibly smaller... I am trying to make the case for the plausibility (now I sound like Adam and Jaime). I am chillin' with a drink right now... and if I blow up or become doomed to be in the team of black hole untrained voyager volunteers then I guess it might be kinds cool after all... just hope that the gravity pull doesn't feel like ejecting from a fighter jet and that there is no laser shredder a'la Resident Evil on the way out the other side...

:D

In the USA, it's called the IRS... :)


I got to thinking a funny video would show a group of scientists adjusting the the collider for the first high power experiment. Once the power is applied, all sorts of lighting bolts fly in every direction killing the scientists left and right with sudden explosions. As a last ditch effort, the 2 remaining scientists, switch the polarity and stop the meltdown. As the collider winds down, one scientist looks at the other ans says,"That was close!!!"

At that point, the second scientist says, "That was terrifing, but I wonder what would have happened if we used more power?" The 2 scientists high 5 each other and start to set the collider for a higher power as the image fades to black...

I think that any school system that lets students get past the 9th grade without being taught about cosmic radiation, for example, is doing those students a real disservice.

I'm not suggesting that junior high school physics needs to include quantum mathematics; teaching people what a gamma ray is, though, doesn't seem like too much to expect.
 
While we are on the subject of education, from my experience I've found that the UK teaching methodology seems to be centered around on "how to figure" things instead of actually learning massive amounts of informtation;

whereus when I talk to international students, e.g from India etc, these guys seem to come from a system that pumps them with TONS of information (which I respect) even the way exams are in my view waaay harder, we had an Indian professor, he use to tell us the UK exams were a joke frankly (as in it was uber easy) from his POV.

Anyhoo, even the weirder thing is, like in my country the maths they learn at college level, is equivelent to a degree level (I've seen the books!)

So I guess its a case of different routes to achieve the same thing, I'm not saying one is better than the other.

I've never had a physics class, they let us choose if we want physics or geology-biology.........Although I was really interested in physics, the subjects I liked weren't thaught so I choosed geology.........poor people that choosed physics lots of them failed........

But I agree we should be thought a bit more about our enviroment (not talking about ecology and all that, but about the matter that sorrounds us).
 
I studied with the British system in Argentina, I guess I see what you mean Anhar. Then when I moved over and went to a public school in Florida I didn't need to take any math at all... but I needed the credits anyway so they let me pick out of the full curriculum, whichever I wanted. Our math teacher was teaching us calculus introduction in our sophomore years.

What you seem to be unhappy with though, Sad Max, is the astrology level... to be honest I never took a SINGLE astrology class. I totally wish I could have. They did however teach us quite a bit of stuff about the cosmos in other classes. Sorry, but I really can't say I know what a gamma ray is from the top of my head. Can you fry an egg with them? Blow up buggs bunny? I do know quite the crap load about geology though. And I'd like to think that my understanding of the universe is at least decent... I do watch the Nasa channel and surf though the JPL site a lot :D

Gamma rays are photons energized to over 100,000 electron volts; the shortest-wavelength/highest energy radiation known. Gamma radiation is present in space, and is the primary initial expression of a nuclear weapon's destructive power.

This is something that you'd expect to be covered in either an introductory physics class, or an introductory astronomy class (maybe even a chemistry class, if the instructor wants to stretch a bit in the atomic-chemistry section).

And yes, gamma radiation would be just dandy, for blowing up an egg, or frying Bugs Bunny...

...mmm...rabbit and eggs...
 
I guess I remember covering the spectrum several times, but never really focusing enough on any given one of them. Perhaps I was busy vandalizing my desk.

Ok, so I go back to the point I had about the mass... you are speaking of one photon traveling alone right? So I ask, aren't the protons being shot at each other going to be squeezed into a very narrow beam where they could all collide together at once, or at least create multiple collisions at once? I have no clue as to how spaced out they are... and what is the difference in mass from a photon to a proton?
 
A proton's rest mass is 938.272309(28) MeV/c-squared, or 1.6726×10(−27) kg, or about 1836 times the rest mass of an electron. Protons are heavy particles.

Photons are massless; if they had any mass they would not travel at the speed of light...

The basic purpose of a particle collider is to focus opposing beams of particles into one another so as to maximise the probability of collisions whose after-products can be tracked and analyzed.

Hear in California, I have to deal with some students that don't even understand fractions. No joke, in our classes, we ask students, "Which is bigger, 1/2 or 1/3?"

Some answer, "1/3"; when asked why, the answer is, "Because 3 is bigger than 2."

Heaven help us....

another nice comparison I read, said: the chances of creating a black hole are about as big if you let 2 large Mack trucks collide headon at full speed and they turn into a Ferrari :-)
 
If we're talking about rest mass - which is what I was talking about - then photons are still massless.

Unless and until we get that big rewriting of physics necessary, to accommodate their having detectable mass, at rest.
 
Have a read through that forum (and I was not talking about restmass), its quite an interesting titbit.

Yea, when you are talking about photons not having mass that is something else... you are talking about energy and mass. That's where the shi* is at. Cause energy has to have a signature in function of mass.
 
Yea... so it still has a relation to respond to. It counts for an effect. So it is and it is there. Potential mass. Or a potential effect on mass. Something.
