During the first COVID-19 days, I had a couple of weeks hiatus between two jobs, which I used to create a popular-math podcast in Hebrew I call "Math Shmath".
There are only 5 episodes so far, but I hope to get some more in the future.
The intended audience is people with no formal math background, but through a listeners survey I found that about half of the responders had at least undergraduate level studies in math or sciences.
The podcast had over 5k downloads so far, and if you are a Hebrew speaker, I suggest you give it a try. It is available on iTunes, Spotify, and all the usual places, and I'm told kid with math tendencies at ages 10-15 like it.
