I'm in the process of reading this (and a dozen other books lol). Interesting so far. Haven't formed opinions yet. But definitely appreciate Bell Hooks bell hooks for having tackled this subject.
ADHD is very heritable, almost as much as height. So it is pretty likely, indeed.
PS: I can grasp math concepts if explained in certain ways. I had to take a below grade level math class in middle school and needed a tutor for algebra. I blame the teachers lol. I somehow managed to get through all the math in my engineering degree (wtf was I thinking?).
Later on in life I struggled to understand Kalman filters until an online course explained it in a really accessible way, and related it to another class that was well taught on Bayesian statistics. It all clicked. But if I stare at typical math textbooks, it might as well be written in hieroglyphics. It just doesn’t sink in.
I wonder if I have this. Edit: no I don’t think I do.
One of the symptoms of ADHD, as I understand it, is difficulties with symbol decoding (I think that is what it is called). I think it may be related to poor working memory. Say you want to decode a substitution cypher. With ADHD you have to keep referring back to the decoding chart more often than those without. (I took a test on this as part of my diagnosis and I sucked at it).
I think maybe that affects understanding equations with all the symbols and Greek letters and such?
I wished they had taught us more context and concept in college EE classes. I guess super smart people figure that out on their own. It took me until several years after college before things started to click a little. I’m still working on it.
Electromagnetics still seems like dark magic to me though. I hated that class because it seems like it should have been the coolest topic ever but nothing made any sense.
Maybe they need to get dumber people teaching this stuff because at some point if you are too smart you take for granted leaps that elude some of us.
I have done teaching in a Corp setting for several years, and I find that all the questions from and confusion of students really push me to explain better, understand deeper, question some of the concepts, etc. (We teach both concept and execution)
I guess either our classes needed to ask more questions or the profs needed to work on their teaching or something.
New research indicates that Homo erectus likely capitalized on a “greener” corridor through the Sahara Desert in northeastern Africa, which was wetter and more vegetated than it is today, during their migration out of Africa. Climate cycles aligned to create this green passage, facilitating their journey.
Apparently the desertification of the Sahara is cyclic.
Approximately every 20,000 years, the Sahara transforms into a savannah covered with lush grasses due to the angle of the Earth’s axis changing. This axis change causes the position of the North African monsoon to shift, a monsoon that could revive the Saharan region. (source)
Here’s a graphic on the timings of early human migration. They list two migrations northeast, one occurring 120k years ago and another 100-90k years ago.
