    Jun 30 2026

Grab a glass, because Will and Mango are serving up the answers—plus a sneak preview of the plant milks of the future.

  • Where Did the Alphabet Come From? with Danny Bate!
    Jun 16 2026

    Why is Z the last letter of the English alphabet (and why do British people insist on calling it zed)? Who stuck a tail on C and called it G? And is there a reason why the I in ‘child’ and ‘children’ sounds different? (Spoiler alert: Yes!) Linguist Danny Bate stops by to unpack the mysteries of the alphabet and discuss his delightful new book, Why Q Needs U: A History of Our Letters and How We Use Them.
