Life works in mysterious ways: mathematical award

My PhD mentor always encouraged me to pursue mathematical studies evenย  after I finish the PhD. He meant differential equations of course. Until he has seen my spiral paper foldings. Once he told me my origami is cooler than differential equations. I hope he’s proud of me, since I’ve got Honorable mention award at American Mathematical Society mathematical art exhibition for my spiral tessellations ๐Ÿ˜‰ I did not expect it, so it’s even a nicer surprise.

I even got to the cover, and more covers are going to appear in the following weeks… stay tuned ๐Ÿ˜‰ Excentrica is in favor this season ๐Ÿ˜‰

Here it is, my darling!

Close look to Excentrica #origami #tessellation

The above and below images are pictures of the same origami tessellation! The above is little stretched and the below is collapsed. The stretch-collapse process is smooth and elastic. The lighting is also a bit different, so metallic pigments are working in a different way.

I need to say several words about Excentrica; I am very proud of it.ย  I not only created the whole thing, as I usually do, but I also found the way of stacking origami molecules. I haven’t seen this way before. (please tell me if you did!). It is consisted of 2 types of molecules: triangular and hexagonal. Half of the triangular molecules point up and half down. In the picture you probably don’t mention that the lightest ones and the deepest ones are actually the same, but flipped. Hexagonal molecules are iso-area by themselves. And the tessellation is iso-area as a whole! Iso-area means that if you flip it over, it looks exactly the same. Which is magical I think.

To understand what I was just telling above look at Energy tessellation below. It is a more usual kind of tessellation. There are lots of straight-fold tessellations which are using the same method of stacking the molecules. One of them is Honeycomb tessellation. Those are just same size hexagons that tile the surface, nothing fancy in mathematical dimension. Although it does look gorgeous.

    1. I have 3 books published for now, try ordering one of them from amazon or ask friends to bring it from US. I don’t know where people get books in Brazil, it might be better to ask people in Brazil how they do that ๐Ÿ˜‰

  1. Your are an amazing person, Ekaterina!! Congratulations on your mathematical award and your PhD. I did not know you were studying math at that level. Does your mathematical background help you in developing your models. Just curious, do you teach mathematics? Tessellation are so beautiful and relaxing to look at..almost mesmerizing. Can’t wait for your next book. I am not able to do a lot or origami anymore. After years of using my hands this way I have developed osteoarthritis.
    But the models in your books are so beautiful to look at. I hope you keep on publishing. Good luck

    1. Thank you for the kind words!
      I am not sure my math background really plays the big role in my origami. I would say it’s more factors that go side by side: my love to puzzles, modulars and origami and my mathematical studies. Those things are just similar in some ways. I think for modular origami school geometry with trigonometry is more than enough. For the curved things maybe more, but more in the direction of intuition.

  2. Oh, great! I too love puzzles, origami and maths……..but I am not as great as u! ๐Ÿ˜ž Any way I just can’t imagine any origami activity to explain calculus. Can you help me?
