"It seems to be a lesson of history that the commonplace may be understood as a reduction of the exceptional, but the exceptional cannot be understood as an amplification of the commonplace.”

Um, let me help you.

Every single lecture is carefully planned, advertised ahead of time, and delivered according to the schedule. Which is the opposite of 'random'.

You are welcome. 😊

In the animation above, you see the approximation of a square wave if we only consider the first four terms (n=1, 3, 5 and 7).

A square wave can be expressed as the infinite sum of odd sine waves with ever-decreasing amplitudes and periods. This is an example of a Fourier transform, a powerful tool in maths & physics that can be used for encoding/decoding information stored in waves. 1/2

That's some serious beef there between Cabibbo and Gell-Mann.

"20 years ago, I used to find the anthropic interpretation of the universe upsetting, in part bc of the difficulty it might present in understanding physics. Over the years I have mellowed. I suppose I reluctantly came to accept the universe was not created for our convenience in understanding it."

A bit of a specialised paper title, but definitely a very accessible abstract.

I am following lots of epidemiologists, Brexit, and Russia experts.

I am not following enough Korea experts. 🫀
