Quasicrystals: The Strange Order That Changed Crystallography

Quasicrystals: The Strange Order That Changed Crystallography

Today, we’re explor­ing qua­sicrys­tals, what they are, how an “impos­si­ble” pat­tern was found in a lab, how it became the cat­a­lyst to rewrit­ing text­books, and why this exot­ic order mat­ters for real‑world tech­nolo­gies from wear‑resistant coat­ings to pho­ton­ics. I’m Gabrielle Bir­chak, and this is Math! Sci­ence! His­to­ry! Imag­ine hold­ing a met­al that seems to obey rules nature once for­bid. You

Euphemia Haynes, Her Math, and Her Fight for Equality

Euphemia Haynes, Her Math, and Her Fight for Equality

A bril­liant math­e­mati­cian once wrote, “For a per­son of intel­li­gence is well equipped to solve the prob­lems of life… we must have some defined aim in life and be able to fill com­pe­tent­ly that posi­tion in which we may find our­selves… let each defeat be a source of a new endeav­or and each vic­to­ry the strength­en­ing of our spir­it of

Abstract Algebra, Swimming and Rummikub

Abstract Algebra, Swimming and Rummikub

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!

Hypatia: The Sum of Her Life — Chapter One

I have good hope that there is some­thing after death. This is a quote by Pla­to that I chose to use for the first chap­ter of my recent­ly pub­lished book, Hypa­tia: The Sum of Her Life. This quote is so pro­found to me because her lega­cy con­tin­ued to live on after Hypa­ti­a’s death. Some were neg­a­tive, some were pro­pa­gan­da, and
