Title card for Mindscape episode with David Tong.

Mindscape 321 | David Tong on Open Questions in Quantum Field Theory. I *know* you've been worried about why the electroweak theory cannot be defined on discrete spacetime. #MindscapePodcast

Love that book

And we are here for it!

I'm quite hopeful too, also that the judiciary will continue to rectify the egregious unlawfulness of the government.

Bluesky is dead eh?

Maybe i am too, what a relief.

😂😂😂

Oh wow, this looks pretty cool! Is this going to be a compilation of his notes?

Please let me know if there's a solution to it, I have had enough lol.

Hey bluesky! Do you want to develop your own open-source software in Python? Apply to attend Code/Astro!

Scroll all the way down for the application link. :) Apps are due Feb 1! (1/2)

watched a good film. maybe everything will be okay after all

2025 will be the year of the Black Hole! Watch Out!

A black and white photo of M31, the Andromeda galaxy. It is characterized by spiral arms and dark lanes of dust and gas, with a bright center.

100 years ago today, #OTD in 1925, Edwin Hubble announced that Andromeda and other spiral nebulae were definitely separate galaxies outside the Milky Way, in a paper read to an AAS meeting by H.N. Russell.

There was no doubt that the Universe was more than just our little island of stars. 🧪 🔭 ⚛️

Happy new year sophia<33

Happy new year :)

Well, in case I'm late to the party.

I can't believe bluesky is this old

One is not like the others 😁

This is the fastest thing humanity has ever accelerated. At perihelion this bad boy goes 191 km/s, 0.06% the speed of light

Can't wait!

THE MAGNETIC LIMIT OF MAXWELL'S EQUATIONS Starting with Maxwell's equations \nabla\cdot E = \rho \nabla\times E = -\frac{\partial B}{\partial t} \nabla\cdot B = 0 \nabla\times B = J + \frac{\partial E}{\partial t} we can take the magnetic limit and get \nabla\cdot E = 0 \nabla\times E = -\frac{\partial B}{\partial t \nabla\cdot B = 0 \nabla\times B = J

Hardcore physics post

Maxwell's equations are invariant under Lorentz transformations. The usual equations of fluid flow are not! Like the rest of Newtonian mechanics, they're invariant under Galilean transformations like

t' = t, 𝐱' = 𝐱 - 𝐯t

So, if we […]

There are plenty of other resources as well. If you like video lectures then please let me know I shall direct you to that as well. Once you are more familiar with the basic ideas, then I'll be happy to recommend more advanced books.

All the best! 😄

1. Special Relativity and Classical field theory by Leonard Susskind.

2. Spacetime physics by Taylor and wheeler (this has many interesting problems).

3. Feynman lectures volume 2.

4. For GR, you may wish to go through Sean Caroll's Geometry of Spacetime.

5. Space, time and Relativity by Wald

I am so happy to know that you are going to grad school for physics! It is always best to review the subject, especially when it comes to something as subtle as relativity. I have tons of favourite resources, but here are a few I really liked!

A new claim that dark energy isn’t necessary, we just need to properly account for inhomogeneities in the universe. Maybe. But his idea has been discussed for a long time - David Wiltshire, an author here, has been pushing it for 20 years, and others have also looked at it. (1/n)
