Octonions?

[John Keith]

Fascinating article about hypercomplex numbers and theoretical physics:

Users of HP48/50 calculators can explore the mathematics with Anion2

Thanks for the link, it's indeed fascinating even if well beyond my math knowledge.

HP-41 users can also work with Octonions.

I am wondering about this fact on HP Prime.
Advanced Mathematics are great.

I just finished Lost In Math, a readable discourse on the state of theoretical physics and a nice counterbalance to articles like this. I'm hardly qualified to take sides, but I found the book interesting and thought provoking.

... this is the YouTube series by Dr. Furey. I found it really fascinating too.
