Exactly. This is a nomenclature issue. When this is spelled out it is easily understood. Math is not the issue here. Should CS students have an intro to abstract algebra? Probably. Do CS students (in those programs where CS isn't conflated with IT) take 3+ years of math courses? Yes.
Anyone who doesn't use that nomenclature on a regular basis is bound to need a refresher legend. The concepts are easily remembered (and used in all kinds of programming). But which direction the e points is less easily remembered.
I learned the details of photosynthesis, the Krebs cycle, and a lot of other basic biochemistry in high school, but I don't remember much of that at all.
I did a fair bit of set work in college, but it took me about a minute to dig some of that up to read and understand the relationship that's being described. I don't think I've worked with sets using actual mathematical notation in over 10 years. It wouldn't have surprised me if I couldn't read it (although I would've found it somewhat distressing).
The weird part is his audience: active students and researchers within the field of CS. They're the ones that I would've expected to be most likely to understand what it said.
200 mg twice a day for 4 years, that's crazy! I'm surprised that guy got any sleep at all.
I use Modafinil _responsibly_ (I like to think) and for me that means 50 mg, taken early in the morning, only on days that I might need the boost (bad night's sleep, busy day, etc).
It's worth pointing out that we're looking at more like 0.65c, through optical fibre. This would also be ignoring routing infrastructure/processing time and network prioritisation.
Fiber optic cables may not be able to penetrate the molten core of the Earth, but there is no law of physics that prevents information from traveling through the core of the Earth. Compare this to the speed of light, which is an absolute upper bound on how quickly information can propagate. There is simply no way, in this Universe, to do better than the straight-line distance through the center of the Earth.
