@astro_nolan Congratulations! Really inspiring work. As someone interested in AI for astronomy, this is exactly the kind of research that excites me.

Two underrated skills that no degree can ever buy:
1.Good behavior and respect toward colleagues and seniors.
2.Optimal utilization of your time during working hours.

These two qualities can outshine any degree in the world.

~2012 must have been like a crazy time.

Neural networks were considered nonsense by most people. Hinton, LeCun and Bengio were the amongst the very few people who kept it all alive for decades.

Alex Krizhevsky, a mad coding genius and a socially aloof kid, shows up to Hinton's lab and says he is bored by the software engineering courses and asks to work there.

Hinton has another student Ilya Sutskever, who is like this mystic guy, who says neural networks are the future and they will outpace human intelligence.

Safe to say most people at this point think these guys are crazy.

Hinton tells these two guys to train a convolutional neural network on Imagenet and specifically tells them to use GPUs. He wants to make machines see.

Krizhevsky goes to town and masters CUDA and parallel programming, and they train a model called SuperVision. Hinton understands the magnitude of what just happened, and tells him to use the name AlexNet instead to carry on Krizhevsky's legacy.

This is submitted to the ImageNet challenge, and Fei Fei Li's student is like "wtf, this must be someone cheating" because it's miles ahead of other submissions. This was most likely the last year for ImageNet challenge because the progress was super slow until then.

Fei Fei Li gets a call and the student says "you better take a look at this".

They can't find out any problem. They test the model on entirely unseen data, and it crushes everything else.

Fei Fei Li is dumbfounded, not just because of the jump in performance, but because it's using this "nonsense" piece of technology called a neural network. She says “It was like being told the land speed record had been broken by a margin of a hundred miles per hour by a Honda Civic”.

Two things happen: people wake up about neural networks. And Jensen truly now (actually only in 2013, but that's story for another time) understands what Nvidia needs to do next.

And then the socially aloof Alex Krizhevsky disappears completely, but his legacy lives on with AlexNet. It is rumored that he is living somewhere in Mountain view, having given up on AI and perhaps technology itself.

Matrix multiplication is now a multi-trillion dollar business.

Food in space. Never thought I would have to learn to eat again 😅. Here I am explaining why habits matter when you are eating in space. If you are not mindful you can easily create a mess and you don’t want to be that guy. Solid mantra that works for anything in space “Slow is Fast”.
Other interesting fact is we don’t need gravity to digest food. A process called ‘peristalsis’ is responsible for digestion which is gravity independent. It is the contraction and relaxation of muscles to push food down through the digestive tract.
Head up or head down, gravity or no gravity your body will always digest food.
Bon appetit. 😊

@akshumarathe_ The overall number of minds is just one. It is merely the consciousness that is multiplied. In truth, there is only one mind.

There are two routes to becoming a physicist.

One is to study physics in college/university. Get into a PhD program. Publish papers on your research area.

The other is to become an engineer and then retire.
