TIL that Andre Geim won the Ignobel prize in 2000 for levitating a frog and then won the Nobel prize in 2010 for his work on Graphene. He is the only person to win both awards.

Intramuscular injections can accidentally hit a vein, causing injection into the bloodstream. This could explain rare adverse reactions to Covid-19 vaccine. Study shows solid link between intravenous mRNA vaccine and myocarditis (in mice). Needle aspiration is one way to avoid this from happening.

I focus on DSP and digital communications + ARM and FPGAs, so will share the ones I liked the most!

(make sure to check online universities, some tend to share lectures online, for example - MIT)

Feel free to note me if you have any questions! Maybe I forgot some good channel, will update this list if I remember more good resources.

Hydrogen Level In Atmosphere Increased 70% To Heat Up Planet, Says Ozone Day Study
https://www.indiatimes.com/technology/science-and-future/hydrogen-levels-in-atmosphere-climate-change-ozone-day-549549.html

Here, in India, we get "Indian Edition" or "South Asian Edition" or "Asian Edition" of American textbooks. These textbooks are usually adapted for these regions by professors of Indian universities.

These editions have altered arrangement of chapters and even topics within the chapters. Sometimes some extra topics/chapters are included, while some other times some topics/chapters are excluded.

This is something I usually dislike, as I feel that titles should be accessible *the way they are* from anywhere in the world.

But, today I was reading the Indian edition of this book "An Introduction to Mechanics" by Daniel Kleppner and Robert Kolenkow, and I was actually impressed seeing the order of arrangement of the topics, which was better than the original American edition (that I pirated).
