Hey Isıkdogan, i really appreciate you for doing that great explanations. You have so much knowledges about learning compared to an ordinary researcers. thank you again.
And one more question : u from Turkey? (:

[@carlmabiog]

It was a great explanation!

[@talelkraiem4757]

already watched your playlist and realised its a game changer !
