FLASHCARDS! Level up your thinking game!

It’s Flash­cards Fri­days. I’m Gabrielle Bir­chak, your host, and today I’m going to do a call­back to Tuesday’s episode, which was about cap­tur­ing thoughts. Last Tuesday’s episode was about pho­tograph­ing thoughts. Today I’m going to talk about those moments where you wish you could have just thought about the sub­ject bet­ter, espe­cial­ly when you’re try­ing to learn some­thing new. But

Flashcards Friday! How to Talk to Someone Who Doesn’t Trust Science

Flashcards Friday! How to Talk to Someone Who Doesn’t Trust Science

It’s Flash­cards Fri­day, and today I want to talk about some­thing that mat­ters as much as any exper­i­ment: how we talk to peo­ple who do not trust sci­ence. Not how to win an argu­ment. Not how to humil­i­ate some­one with a fact. How to build a bridge. Because sci­ence does not spread by vol­ume. It spreads when peo­ple feel safe

Hobbes v. Boyle: Who Decides Scientific Facts

Hobbes v. Boyle: Who Decides Scientific Facts

In the 1600s, philoso­pher Thomas Hobbes and exper­i­men­tal sci­en­tist Robert Boyle clashed over a strange new machine, the air pump, and a dan­ger­ous ques­tion: when should soci­ety trust sci­en­tif­ic claims, and who gets to decide? Their dis­agree­ment wasn’t just about experiments …

The Sun Dagger: How Ancient Puebloans Made Calendars from Sunlight

Before cal­en­dars were print­ed, before clocks ticked, and before num­bers were writ­ten, humans looked up. We looked up at the sky not just to admire the beau­ty of the stars and celes­tial bod­ies, but also to pre­dict the best times for plant­i­ng and har­vest­ing crops. So stargaz­ing was not just an enjoy­able endeav­or; it was a method of sur­vival. In

The hol­i­days have end­ed, the dec­o­ra­tions have come down, and many peo­ple have stepped out­side to find that the ground has been qui­et­ly trans­formed into a dense, slip­pery physics problem. 

FLASHCARDS! The Riddle of Love

FLASHCARDS! The Riddle of Love

It’s Flash­cards Fri­days, and today I’m going to talk about some­thing qui­et­ly uni­ver­sal about what humans do when the year begins to slow down. Across cul­tures, across cen­turies, when the days grow short­er and the nights stretch long, peo­ple gath­er. They sit clos­er togeth­er. They talk more. They tell sto­ries. And again and again, they pose ques­tions that do not

The History of Jigsaw Puzzles

The History of Jigsaw Puzzles

You might not think of jig­saw puz­zles as sci­en­tif­ic objects. They seem sooth­ing, domes­tic, almost med­i­ta­tive. But behind every lit­tle card­board piece is a sur­pris­ing­ly rich sto­ry, one that spans glob­al explo­ration, tech­no­log­i­cal inno­va­tion, Vic­to­ri­an par­lor cul­ture, eco­nom­ic upheaval, wartime mate­r­i­al short­ages, cog­ni­tive sci­ence, and the dig­i­tal age.
