It's time to create a new channel named "Fifteen Minute Papers". I can not get enough from these things.

The courses you provided for free is a very admirable gesture, I greatly appreciate it.

Good one.

I recently started you courses, it is truly amazing that it's free! Thank you so much!

Dear Károly,
Thank you so much for sharing the knowledge paper after paper. You're honestly one of my strongest sources for this type of technical knowledge 🤔
I always love your enthusiasm & crack up laughing each time I see the little paper holding symbol lmao I had been watching you for a good while & the first time you used that I died laughing 🐒what a time to be alive! It'd be interesting to track the developments in certain tech chains paper to paper & measure actual rates, see if it aligns with any pattern such as the '2 papers down the line' hypothesis, Moore's Law, etc...

Károly making entire courses available online for free? What a time to be alive!!

1:09 "So if someone says that you look old, you have an excellent excuse now." Actually I should be worried, because they are seeing my past self. I'm older than they see me.

I love this channel so much.
I honestly get a little giddy when I see a new video is posted.

I'm just flattered that you made the course accessible for everyone. Gret, great, great.

[borisangelis]

You are not only an amazing teacher and professor but also an amazing person for providing all that knowledge for free

[illbience]

Incredible. Thank you for making the course available.

This method of rendering is... calling it revolutionary would be a gross understatement!

Not only do we get results that exceeds most other rendering methods, but we also get an unbelievably satisfying way of seeing the rendering in progress!

But this could *also* be used to visualize how light is affected by lenses, mirrors, filters, etc.! A massive help for companies developing lenses, mirrors and filters for things like cameras, binoculars, microscopes, telescopes, etc.!!!

the future of education is going to be so "lit"

My feet are 5.5 nanoseconds in the past. No wonder I'm always tripping on things!

[sarahsaad-masri]

I love watching your videos so much! They’re so educational and always manage to get me to read these papers!

[jasonhemphill]

Thank you for releasing that course! I can't wait to get started!

[anferrr]

I'm really bad at math so I could follow a course like yours... But god this is cool that you are giving people this opportunity. From the bottom of my tiny geeky heart, thank you ^^

[iliasamri]

Hello,
I don't usually comment, but I wanted to thank you for sharing you class.
It's a invaluable ressource ! Thank you !
