I'm an engineering student that does programming and am wondering, can I ask what are some good resources to gain the appropriate background that would allow me to understand more of this notebook? I have used tools like Numpy but probably not very efficiently without understanding their strengths and weaknesses. What books or online courses should I look into to know about memory, flops, and things like that?

I should probably ask this somewhere else but I'm not sure what the appropriate forum is, if you could point me to where I should that would be great. Thank you!
