So beautiful!

Am I watching Wheel of the Worst?

woody is a genius artist and performer! one of a kind!

Jealous of the size of the screen - I implemented life on an 80 column 24 row screen - much less impressive, continually scrolling to see what was there.

Michael Serra's Pirate Math sampler can be downloaded from www.gathering4gardner.org/g4g11gift/Serra_Michael-Pirate_Math_Sampler.pdf

This sounds like a very important discovery. Thanks!

What a cool idea!

If you didn't want to 'relax the constraints of the problem', you could use a single extra die with only one stable face and exactly one pip. Granted this would require an extra pip, but at least it would be working a 24-hour day!

Delightful! You probably don't remember be, but I took a wonderful undergraduate discrete math course from you as a sophomore at MIT in Fall 1991. Thank you for everything!

This is fascinating! Great talk!

First comment on a fractal video, huzzah! Kudos to Douglas McKenna for a great presentation on great work.

This was really interesting and informative!

I heard about this brilliant idea in March this year, and have been writing them consistently ever since. It has been so therapeutic for me. I hope to find other people who appreciate this like I do. @scrabblegrams_by_landon is where I have been posting them! “A hundred-letter quote I show Ut(i)lizes just one of every tile in Scrabble Provi(n)g again, I can mark a good poem In a fixed way”

I was interested in seeing if Dr. Schattschneider had any lectures on on KZbin and I discovered this interview. This is great! It's too bad this area of math is underappreciated.

Thank you 🤠🇱🇷🇮🇳

What

Short and sweet!

Amazing! Do you have a compiler?

impressive

I have no words. Just 🤯🤯🤯

Beautiful 😍

wonderful

The flexagons are beautiful.

This is truly amazing! Thank you!

If you think consensus is required to demonstrate accuracy you'd better not be voting. But, then again, if you lacked that level of reasoning to begin with the thought would never occur to you. 😂

I see that some moves decrease the energy. I.e those which increase the distance to the target. But sometimes this moves have to be done to connect the beetles. I think, thats why an energy higher than 1 is no guarantee to succeed. Very interesting problem. Easy enough for interested but non-professional mathematicans but demanding,

So cool! I had to do a triple take on the question before settling on the answer, what ended up warking was imagining to put a clothes peg on the vertex the back arrow pointed to, and re playing the whole sequence in my mind.

It was so great to be at Gathering 4 Gardener with you! This was a great presentation and such an awesome story behind the creation of HyperTiles.

I highly recommend Robert's book "Opt Art". As an amateur generative artist it has given me lots of inspiration.

That is super cool!

Wow🎉

These might have some interesting applications in 3D printing. A single line path is ideal for creating a layer, avoiding problematic non-extrusion moves, and imagine creating infill images inside of an object printed in translucent materials, or even in top/bottom layers of an object.

Go to Cracking the Cryptic and TanTan was a guest solving a number of puzzles. The speed that she solves is ridiculous. She is the fastest female and in the top 5 overall in the world.

A glass case would eliminate dust (its enemy) - and have you ever run it in a vacuum?

Great video! Another method: The Walking Compass / String of Pearls. 1. Draw an arc across the arbitrary angle. 2. Bisect the arc. 3. Position 3 circles of equal size across the arc like pearls on a string. The middle circle is centered on the bisection point. The contact points between the 3 circles mark the trisection lines. [To determine the radius of the 3 circles with the compass: 1. Put one side of compass at arc bisection point. 2. Increase the span of the compass from approximately 1/8th angle (approximate or by 3 bisections), until it can walk (plant one side of compass, pivot other side in semi-circle) across the half angle arc in exactly 3 steps. The compass then spans exactly 1/6 the angle. Then draw circle at arc center. At arc intersections, pivot and draw the 2 adjacent circles. The 2 trisection lines go from the angle origin and form a tangent to the 2 points between the circles.] CH 2024

So this isnt about Ukraine?

Ooooh I'm the 1000th view. As you were.

01:40 Excuse me? On the contrary, the sloping lines _are_ colinear. Angle your device so that you can look along them. [Edit] The triangles were great, though. I could intermittently 'see' a drawn boundary line. :)

Can't get this one. What I have figured out is that, if the product doesn't help, at least one isn't a prime. Further, the components of the non-prime sometimes mean that set of numbers is ambiguous, so the product doesn't help there either. (e.g. 1-5-3-4 and 1-10-3-2 have the same product)

Enjoyed this session a lot. Helped me understand the Conway criterion more clearly.

Man you should study about your guest a little bit before inviting.

I recognise this trick but cannot recall where I have seen it of who created it. Does it jog anyone mind?

There is an old paper by Uri Zwick www.cs.tau.ac.il/~zwick/papers/jenga-SODA.pdf But the Jenga pistol ruins all the theory : www.cs.tau.ac.il/~zwick/papers/jenga-SODA.pdf

love how he pretends to know the math behind the principle,

What a lovely appetizer. So looking forward to the full videos. And well done for name checking the students that had something unique to contribute.

Thanks for sharing this online. So interesting hearing all the stories and anecdotes about Kreskin. Even the MicroSoft Word app knows who Kreskin is.

Stoken! Just the best of the best!

That's amazing. Any chance we can know the 5 (disjoint) sets of 60 numbers?

Never heard of this type of work before. Seems fun :)

Oh I'm so glad to see Ivars Peterson still doing math in his day-to-day and sharing it with people in a fun way.
