I wanted to keep the UI from getting too busy, which is why I limited the degree to 7. But if somebody really wants to play with higher-degree polynomials, I'm not going to stop them!

I was just pondering about this. I imagine that moving a coefficient a small amount (and so long as the roots are not too close) that Newton-Raphson, initialized with a previously-known root, would converge very quickly to the new root whil

I believe every radio telescope has their own reference clock that lives at the site. The EHT team is not responsible for schlepping these clocks around. There are other reasons besides VLBI to have really good timing at the site—for exampl

> fixed-length binary strings are a group where the operation is xor (or '^') and inv(x) = x Most people would call this group (Z/2Z)^n, i.e. n copies of Z/2Z under addition. Similarly, for "matrix addition" you could say Z^(mn) or R^(m
