Since CT involves ionizing radiation, an overarching thrust of related technical research is development of novel methods enabling ultrahigh quality imaging with fine structural d... | CommonCrawl |
How much of the sky can the JWST see?
To turn and point at different objects in space, Webb uses six reaction wheels to rotate the observatory. The reaction wheels are basically flywheels, which store angular momentum. The effect of angular momentum is familiar in bicycle riding. It is much easier to stay up on the bik... | CommonCrawl |
When Alpha is submitted the equation $a(a^2-1)=2b^2$, it unexpectedly forgets the integer solution $a=1,b=0$. What could explain this ?
I have observed that the anomaly disappears when the resolution is explicitly asked over the integers (the qualifier Diophantine also works).
So it seems that the flaw would be in the ... | CommonCrawl |
I am a graduate student in the Harvard Department of Mathematics, working with Mike Hopkins. My interests are in homotopy theory, category theory, and algebraic geometry (and the intersection of these). My recent projects have focused on developing a theory of localization of types in homotopy type theory (analogous to... | CommonCrawl |
