While I agree with the author broadly, he is definitely overselling his thesis. Going from 'fewer grad students now care about problems in Journal of Algebra' to 'Math is running out of problems' is quite a stretch. Take

many of the tricks we learned in the late 90s - 2000s can no longer be pulled off. We used to download jar files over the net. Running a major prop trading platform meant 1000s of dependencies. You’d have swing and friends for front end tab

using just the ABS gives you the LAD. least absolute deviation is not used for a couple of reasons. LAD doesn’t have a unique solution - you can code it up and your program will give you a set of solutions which will all minimize the LAD. t

if the probability that you get a derivative close to 0 is small, say only 10%, then you need just 3 dimensions to get that multiplicative probability equal to a tenth of a percent. 3 is hardly “very large dimensionality” you can assign dif

I don’t believe any of the comments below address the meat of your question - what value are you getting from the equation ? I would answer- not much. You can think of BS as a curried function. Since all the other params are fixed, you can

Sir, I worked thru your dog & cat adoption example. I had a few questions. So you have x & y vectors, and want the vector z, as below: x<- c(1,2,3) y <- c(4,5,6) z<- c(1+4, (1*2+4*5)/(1+4), sqrt((1*(4+9) + 4
