I'm a professor in the Mathematics Dept. at M.I.T. I mostly work on quantum computation, quantum information, and quantum complexity, but I am also interested in other areas of theoretical computer science and mathematics.

 Dec20 awarded Editor Dec20 revised Where can I learn about transforming uniform, random distribution into other distribution edited body Dec19 awarded Teacher Dec19 comment Where can I learn about transforming uniform, random distribution into other distribution For one dimension, inverse transform sampling is indeed a good thing to use. The problem with discarding points outside a sphere is that in high dimensions, you end up discarding nearly 100% of your points. Dec19 answered Where can I learn about transforming uniform, random distribution into other distribution Dec19 comment Where can I learn about transforming uniform, random distribution into other distribution @Jerry: Generating one angle between 0 and 360 and another between 0 and 180 DOES NOT WORK! A point near the pole is much more likely than one near the equator. Dec19 comment Where can I learn about transforming uniform, random distribution into other distribution Or, for much larger dimensions, you could choose $n$ points from a Gaussian distribution with mean 0 and variance 1, and normalize them. This gives a random direction. Feb27 awarded Supporter Feb21 comment What is the most accurate way of determining an object's color? It's not just obviously coloured light. I am pretty sure that sunlight, fluorescent light, and incandescent light have colours that are different enough to mess up HSB colour-matching, even though our eyes somehow adjust so that we don't perceive things changing colour. Feb21 awarded Autobiographer Feb21 comment What is the most accurate way of determining an object's color? Let me comment that although switching to HSB color-space may help some, it will certainly not completely adjust properly for arbitrary lighting (even in theory). For that, you would need to use something more complicated, possibly looking at the difference in colour between the coins, although I don't have any concrete suggestions.
