    ICYMI: Rank measures how many rational solutions to an equation one needs in order to find every other rational solution. For decades, mathematicians believed there was no limit to the rank of an elliptic curve. Not so, says a new model.

    I was trying to bring some order to my bookshelves when I came across my copy of “Littlewood’s miscellany” and started browsing. I promise I am never going to complain about my teaching load again.

    Proofread your papers, everyone. Seen at the end of an arXiv paper today with ~100 authors: "Acknowledgements go here. Include support staff at STScI - does somebody have a complete list of people we should mention?." I guess not...

    Hello, fellow academics! I’m helping with a new study on how PhD qualifier/prelim exams affect the mental health of grad students and would love input. Were your prelims/quals stressful? How did they affect your well-being? Any thoughts on them in general?

    One thing I'm learning this semester: surfaces (especially Riemann surfaces) are really cool and seem to show up everywhere.

    Don't assume good health is forever. Don't assume a sharp mind is forever. Don't assume your loved ones are forever. Don't assume you have unlimited time. Do the things you want to do while you have the opportunity, and hug your loved ones close.

    Quaternions and Euler angles are discontinuous and difficult for neural networks to learn. They show 3D rotations have continuous representations in 5D and 6D, which are more suitable for learning. i.e. regress two vectors and apply Graham-Schmidt (GS).
