Everyone ready for Sunday Punday?? A mathematician walks into a bar and say "I'll order 10 times what everyone else is having!" The bartender says "Wow, that's an order of magnitude" 😂 🤣 😂 🤣 😂 🤣

Love the art here. What do you see?

Why did the sound engineer change so much after college? .... He had a FourYear Transformation. 😂

Pick your favorite and tell us why!

I love these math animations. Anyone know of a good place to find more? Check it out - the Area of Cycloid = 3 x Area of Rolling Circle

Oh man, I goofed on this one. Amplitude and volume...🤦‍♂️

In case you have trouble remembering the relationship between amplitude and pitch...

Nifty little video on the Covid genetic sequence

Congrats to everyone #graduating in 2020!

There's positive thinking even in negative thoughts.

I love my mother. My mother loves wine. For mother's day, I thought I'd use some #statistics thinking to help her finally resolve, once and for all, which wine is the best wine. #HappyMothersDay #MTBoS

Love this! Teachers, what are your practices in encouraging self-exploration with students?

ha I didn't know paperclips could be cute

Can't forget those 45/45/90's 😂 😂 😂

Found this neat #corovonavirus #mask graphic.

So apparently, glazed donut/bald eagle is a unit of time. Twitter, let's hear your wackiest made-up unit of measure.
