Emoji Differential Equations: Dreidels as Euler Angles

Here is my latest set of emoji differential equations.

And in case you want a holiday-themed system of emoji differential equations, here are ones for unsteady precession of a dreidel.

Enjoy the holidays!

Upside-Down Dreidel Spinning

I prefer upside-down dreidel spinning. (It's in the wrist.)

As a kid, I didn't think spinning dreidels the normal way was sufficiently interesting, so I cultivated spinning them upside-down.

Tales from the ArXiv: "Dreidel Fairness Study"

There's a new paper on the arXiv preprint server called Dreidel Fairness Study.

I am amused by the following line from the abstract: "Although an unfair dreidel does not necessarily make the game itself unfair, it is conjectured that hundreds of pounds of chocolate have been distributed during Chanukah under false pretenses."

Also, the abstract mentions a dreidel with the face of Santa Claus on it. I guess they're mixing metaphors?

P.S. Somewhere in my parents' home lie my massive collection of dreidels. I can do a spiffy job of spinning them both in the standard fashion and upside-down.

Best. Slogan. Ever.

A "sport" called Major League Dreidel has the best slogan ever: "No Gelt, No Glory!"

I approve!
