Baths and Quarks: Solitons explained

David Tong again in my humble blog. This time, trying to explain what the solitons are. Directly extracted from YouTube’s sinopsis of the video:

In ‘Baths and Quarks‘, theoretical physics expert David Tong explains solitons and their effect on quarks and protons. ‘Solitons‘ — solitary waves which can be seen as bubble rings in the bath — make it impossible for quarks and protons to be separated, thus holding together the universe, he says. “Baths would be so much more relaxing if they weren’t so interesting. Bubble rings – there’s something strange and unnatural about these objects – so structural where you wouldn’t expect to see structure. When I get out of the bath and pull the plug, there’s a world of water that drains away – a vortex – it’s very similar to the bubble rings, and objects like these may just hold the key to one of the most important problems in particle physics [relating to quarks and protons]. My name is David Tong. My job is to understand the beautiful things that I see in the world around me. But to describe them properly, I have to understand them in the language in which nature is written.

A short definition from Wikipedia:

soliton is a self-reinforcing solitary wave (a wave packet or pulse) that maintains its shape while it travels at constant speed.


Physics rulez, don’t you think so?


The Feynman Lectures on Physics

One entry just to note down a link to The Feynman Lectures on Physics, a website by Caltech that honors the three books written by Richard P. Feynman, Robert B. Leighton and Matthew Sands, based on the introductory Physics course taught by Feynman, father of QED (and one of my favorite physicist of all time) at Caltech from 1961-63.

At the moment, the first volume (“mainly mechanics, radiation and heat“) is completely available online, for free.

I’ll keep on visiting its website from time to time. Love it!
