    New Things

    • I am on paternity leave during Fall 2021, and so will be less responsive than usual.
    • In January 2021 I published a book entitled Proofs: A Long-Form Mathematics Textbook. More information can be found in the Book(s) tab on the left or on its page on Amazon.
    • In July 2019 I published the 2nd edition of a book entitled Real Analysis: A Long-Form Mathematics Textbook. More information can be found in the Book(s) tab on the left or on its page on Amazon.
    • In August 2019 I launched the website LongFormMath.com. It is a companion website for my books, and is growing into a more general website for undergrad math. More soon. Hopefully.
