Ragunther ,


I teach middle school math and this podcast is renewing my enthusiasm in teaching! I’d love some more episodes! They are really helping me!

a_dumb_ox ,

These are amazing please do more.

YEARS AGO YOU SERVED MY FATHER IN THE CLONE WARS. this is out most desperate hour, help us GRANT SANDERSON we need more math podcasts.

Bullfrog245 ,

Fantastic interviews!

Grant is an expert interviewer. He makes his guests the focus and keeps things moving with wonderful questions. The most advanced math class I ever completed was Algebra II, so I don’t understand everything that is being said, but I find the stories of the guests to be endlessly fascinating.
