http://arxiv.org/ usually pre-prints all particle physics publications, including those of the various groups at the LHC. I believe it is run by Cornell, it is free.

Additionally, there are conferences every month, as well as every week, in which people present the new findings. You probably cannot get access to the weekly meeting, but the monthly ones will usually make "presentations" you can find online or even on http://arxiv.org/..

Your best bet it to find out what kinda particle physics you are interested in, then search for the corresponding conference (there are fucking tons).

There are tons of sub-fields in particle physics, tons of research groups, and tons or papers/conferences.

If you are interested in science at all, you need to develop your research skills (how to find the information you need). Good luck!

>surely there are examples in physics where i and -i both have valid interpretations

Interpretations in terms of the "math" or the "undelying physics" maybe. But as far as "observation", and "experimentation", they are indistinguishable.

We cannot observe imaginary values in any way, shape or form. i and -i, will produce the same observation.

FYI: I have a degree in pure math as well

Yes

>but how the fuck is there no energy transfered while tunneling through a barrier?

Cause this is not shitty classical mechanics. You best throw out all your 'macro scale' preconcieved notions, they will not help you. It is not like the wavefucntion is a physical entity. It is not a particle that physically travels through the barrier, so stop thinking of it that way.

Inquiry, /sci/.

I'm a biologist and very badly educated in statistics, but about to write my first paper. Let's assume the following:

>Triplicates per experiment
>3 independent experiments
>each of these three experiments yields a mean value and, of course a SD for its triplicates
>journal of choice wants three experiments summed up as one value + SD.

How do I calculate the SD of three independent experiments which themselves of an SD of triplicates?

Thank you.

"Least action" is simply the "Cal of variations", which a mathematical truth in the same sense "pi" is.

For the boundary, you would probably actually use a defintion of temperature related to the degrees of freedom. Becuase it is exotic material, it will have some fucked up degrees of freedom. Likewise it is actually possible to get negative temps and imaginary temp, it gets really fucking complicated.

/sci/, i have a statistics question.

I have several mean values with corresponding standard deviations. I need the mean value and the standard deviation of those values.

Could you help me out with this?

Thank you!

(inb4 highschool fag, I'm a biology PhD student and my statistics lessons were 6 years ago, inb4 OP can't inb4, I don't give a shit.)

Particle physics gives me a hadron.

>General and Special relativity still consider to be the basis for modern physics

Well they were never thrown our, but
they aren't the basis. I don't think they were ever the basis. The term
modern" usuall refers to QM, and eveything after that. SR is usually considered Classical Phyics. Its "Classical Field theory" .
