The equation solved is f(x, y, z, u) = x + y * y + z * z * z + u * u * u * u = o.

I was administered a VVF Test on Wednesday, January 15, at Dr. Brent Brown and Associates Inc office in LaGrange, Georgia. The test consists of using a headset that has an orange circle in the center of the display. The examinee has a trigger device to click each time a white flash occurs. I decided to write a C/C++ Win32 application to simulate the VVF Test. The following two pictures are from a simulated test of one minute in duration. The white flashes are separated by 1000 millisecond (1 second) and their durations are also 1000 milliseconds (1 second).

Blog Entry © Wednesday, January 8, 2025, by James Pate Williams, Jr. Elon Musk’s Ambitious Supercomputer Thoughts
Elon Musk’s choice of geographic location for his Collossus supercomputer, namely, Memphis, TN, was probably a bad choice. A better site with more TVA (Tennessee Valley Authority) power support would have been Oak Ridge, TN. The Collossus name probably came from the science fiction book Collossus: The Forbin Project by the British author Dennis Feltham Jones which was copyrighted in 1966. A movie by the same name was released in 1970. Elon Musk’s AI entity is named Grok which is a verb from the science fiction novel Stranger in a Strange Land by Robert A. Heinlein. Grok means to deeply understand. The supercomputer may one day consist of 1,000,000 Nvidia Graphical Processing Units. The computer’s power requirements are enormous.
