    07. Richard Richards is a Gay Scientist

    Get PDF
    A little recognized and under-appreciated fact about the august Richard Richards is that he is a gay scientist. I know what you may be thinkingā€”Richardā€™s never shagged dudes, and if he has, itā€™s shitty to out him in an essay thatā€™s meant to honor him. Thatā€™s strictly his business. Or you may be thinking that that Richard identifies as a philosopher, not a physicist, biologist, or even (egads!) a psychologist. As far as I know, you would be right in both casesā€”and it would be terrible to call him out--despite the fact that this will hardly rise to the level of an essay. No, what I mean is that Richard Richards practices the sort of approach to philosophy that Nietzsche prescribes in The Gay Science. Now, I wonā€™t pretend to know fuckall about Nietzscheā€”but thatā€™s okay because there are roughly 7,500 budding philosophy majors lurking in coffee shops, craft breweries, and organic grocery stores around the country whoā€™ve got him figured out and would be delighted to expound on my ignorance. If you are genuinely curious about whether Iā€™ve got Nietzsche right, ask one of them. Or read some Nietzsche. In any case, Iā€™m not entirely convinced that getting philosophers ā€œrightā€ is the point; rather, good philosophers plunder brilliant ideas from better philosophers or scientists, looting those concepts for their own endsā€“just ask Schopenhauerā€”and I think Richard might agree with this (c.f., his devotion to Provine and incongruity theory).

    New Lower Bounds for van der Waerden Numbers Using Distributed Computing

    This paper provides new lower bounds for van der Waerden numbers. The number W(k,r)W(k,r) is defined to be the smallest integer nn for which any rr-coloring of the integers 0ā€¦,nāˆ’10 \ldots, n-1 admits monochromatic arithmetic progression of length kk; its existence is implied by van der Waerden's Theorem. We exhibit rr-colorings of 0ā€¦nāˆ’10\ldots n-1 that do not contain monochromatic arithmetic progressions of length kk to prove that W(k,r)>nW(k, r)>n. These colorings are constructed using existing techniques. Rabung's method, given a prime pp and a primitive root Ļ\rho, applies a color given by the discrete logarithm base Ļ\rho mod rr and concatenates kāˆ’1k-1 copies. We also used Herwig et al's Cyclic Zipper Method, which doubles or quadruples the length of a coloring, with the faster check of Rabung and Lotts. We were able to check larger primes than previous results, employing around 2 teraflops of computing power for 12 months through distributed computing by over 500 volunteers. This allowed us to check all primes through 950 million, compared to 10 million by Rabung and Lotts. Our lower bounds appear to grow roughly exponentially in kk. Given that these constructions produce tight lower bounds for known van der Waerden numbers, this data suggests that exact van der Waerden Numbers grow exponentially in kk with ratio rr asymptotically, which is a new conjecture, according to Graham.Comment: 8 pages, 1 figure.
