Math! Science! History!

My last post was about the life of Évariste Galois and his con­tri­bu­tions to abstract alge­bra. Between that pod­cast and my recent addic­tion to Rum­mikub, this thought process then led me, or dis­tract­ed me, to think­ing about num­ber sets and groups. These math­e­mati­cians have writ­ten about groups, then about swim­ming, and the cur­rent Olympic tri­als for swim­ming, which then con­ve­nient­ly led me back to abstract alge­bra, which was the top­ic of my last post on Evariste Galois. My brain went full circle!
