Title: Physics News and Cool Stuff
Post by: jamonwindeyer on June 08, 2016, 11:29:16 am
This is a thread where people can post cool happenings in Physics, new discoveries they've seen in the news, or just general weird stuff.

Question: Is the speed of light in a vacuum a physical constant?

Well, yes, but no. Physicists have managed to slow down light in a vacuum in a few special circumstances, and here is one 8)

Even though this is somewhat older now, Gravitational Waves being discovery is something that was groundbreaking, confirming Einstein's Theories. Still cleaning up his work 100 years later. Here is a video if you want something a little more indepth and easy to understand regarding gravitational waves

PS They sound pretty funny

A lot of things are becoming somewhat old. They're also making progress on type II superconductors. There's also images of black holes now.

Im gonna do my physics PhD on blackholes hehehe

Wonder where you got the idea from

Not really new ground breaking physics but...

Been studying statistical mechanics for a while and I am really awe-struck by the Canonical Ensemble, which expresses the ratio of probability between two states is given by:



From this simple relation, the fact the states with higher energy have much less probability of occurring can be used to prove all the important the results of thermodynamics, hence serving as the bridge between thermodynamics and kinetic theory. This makes statistical mechanics such an elegant theory 8)

Ahhh portal, gotta love it  8)

We are getting closer to proving the existence of Hawking Radiation around black holes.

When I/someone else say that orbits are not perfectly circular, this is a great explanation of what we mean ;D

I read it in James Bond and Villain voices, whatever that is  8)

This is why physicists are better than chemists.

Thank god I have no friends doing chemistry :P

I think this thread is worthy of a revival, because we've got big news!!

As of May next year, we have new definitions for a whole bunch of SI units - The kilogram, the ampere, the mole and the kelvin. The value of a volt and an ohm is actually changing (ever so slightly), while the value of everything else is being fixed to a physical constant ;D

(Use this thread to share cool Physics news, videos, and memes ;))

And then our hopes and dreams get crushed when they vote to keep that "reference" platinum-iridium block

Kidding ofc

That's why I waited until they had voted to share ;)

Oops, I must be out of it. I thought the vote hadn't happened for some reason :P
