An upside down A, two of them. A single inverted A is used by mathematicians to mean "for all". I first appreciated the symbol by reading Jamie Milstein's Ph.D. dissertation. I know nothing much more about him than that he was working for Melvin Calvin who won a Nobel Prize for elucidating the dark cycle of photosynthesis. Calvin did his work right after WW II with the research still fresh from developing the atomic bomb he fed C-14 Carbon as CO2 to plants and harvested in a time course to find out where the carbon was elaborated by the plant's biochemistry. Thirty years later Calvin was still using the data he collected to crank out graduate students.
Milstein was a Biophysicist and assembled a system of 17 non-linear differential equations in 22 parameters and used Bremmermann's Optimizer which is an annealer I found out last year and the then super computer, the CDC 7600 at LBL to solve the problem of determining what the values were for those 22 parameters. The upside down A means 'for all'
Two A's for Aspergers and Autistics.
Both are weird. Charles Perrino who was at one time Chairman of CSUH's Chemistry Department where I got both BA and MS obliquely called me weird after a few beers at a Chemistry and Physics Department get together for pizza and beer in 1974.
So: Weirdo Liberation Front

I took the code for Bremmermann's Optimizer, written in Fortran and translated it into C. I compiled it as a code resource and incorporated the ability to accept code resources into my implementation of the programmable emulator of the HP-15C.
