in college I read a research paper by a university professor who taught himself to generate random numbers in his head that passed tests of randomness as well as high quality RNGs. wish I could find it.
He references the 1980 paper here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1348111/pdf/jeabehav00055-0055.pdf
"After considerable training, I learned to be "random"- that is, my performance could not be distinguished from that of a computer-based random-number generator, according to some 30 different statitical tests. People, I therefore hypothesize, can behave "randomly," that is, in ways that cannot be distinguished from computer-based random distributions."
Revel in the marvels of the universe. We are a collective of forward-thinking individuals who strive to better ourselves and our surroundings through constant creation. We express ourselves through music, art, games, and writing. We also put great value in play. A warm welcome to any like-minded people who feel these ideals resonate with them.
