If you are a theoretical physics grad student right now, you might feel tempted to outsource all your work to LLMs.

This may feel beneficial in the short term, but it can be harmful in the long term. A PhD is a training period where you develop your knowledge of the subject. You learn to recognize good ideas and promising research directions and spot errors and unpromising avenues. These skills, which are going to remain important in the near future, can't be learned except by doing.

More broadly, the ability to think, problem-solve and communicate are going to be your selling points in the job market, whether in academia or industry, at least till the time everyone starts carrying pocket-Wittens. The ability to write prompts won't get you hired.

This is not to say you should not use gen ai in your work, but that you should prioritize your development as a researcher over the temptation to optimize quantitative metrics like number of publications.

Happy days! A perfect excuse to share my favourite quantum cryptography origin story, as recounted in Brassard’s paper:

One of the last letters written by Rutherford. This was to Raman dated 3rd Aug 1937.

Here, he is consoling Raman after he quit the Directorship of IISc. Rutherford is also discussing his possible travel plans to India.

Unfortunately, Rutherford died on 19th Oct 1937..

Nano Banana Pro is a really good cartographer. Used it to turn low res satellite imagery into a detailed hand drawn map and vector HD map.

Pretty wild how well it segments everything and even recovers paths/roads hidden under tree cover.

Looks way more detailed than the current google basemap which is pretty sparse in countries like India. Included both in video for comparison.

In the past 14 yrs of my research group, I have made a few policies for myself, which may be helpful to others:

A 🧵

1) Any group member is free to criticize my input with reason. This has been one of the most liberating experience. Importantly, it has helped me learn.

"A calculator app? Anyone could make that."

Not true.

A calculator should show you the result of the mathematical expression you entered. That's much, much harder than it sounds.

What I'm about to tell you is the greatest calculator app development story ever told.

[Gautam Menon @MenonBioPhysics]

A great story, also involving the founder of @IMScChennai

I will be at IIT Madras today, talking at the EE department on channels with multiple views (joint work with Nir Weinberger). These are of immediate application in the study of DNA-based data storage models.

Do attend if interested!

i bet academics who publish a lot while also teaching and raising children have failed to watch as many shows as i have

Yes, I can. 🧵
