What a wonderful presentation! Zhenya rocked it!

Wow! Thanks you UPR for posting this. I'll try to make it on Tuesdays. Ms. Zhenya Gershman, thank you for sharing Durer's work. Hat's off to you.

[@Figueiredoartconservation]

Wonderful information, THANK YOU SO MUCH, for this beautiful explanation.🙂

Glad I watched this. Incredibly educational, and a wonderful perspective of Durer's work. I really love this piece.

48:38 By fiddling with SketchUp, I can see that, unlike the Star Tetrahedron, his shape eliminates the lines crossing in the center of the projected Star. There are lines extending out from the points and there is a border, but no lines inside the Star of David. Neat trick.

[@DarkMoonDroid]

I can't figure out the proportions of the cut lines, but I have the general shape and I know how it was constructed. XLNT

I see on Wolfram's Alpha page for this solid, he/they claim that Durer starts with a "distorted cube which is first stretched to give rhombic faces with angles of 72°." LOL No. These people do not "distort" solids. That's unholy. He started with the tetrahedron and cut the long edges by drawing 36° up from each bottom edge to the top and then down each side. Twice 36 gives you 72 - 1/5 of a circle. Doing this also automatically gives you the 108° on each side - 1/3 of a circle. Both sacred. Then those tips are chopped off. The top is chopped off to give the 126°. There is no way to avoid this number if you evenly chop off the top of a tetrahedron. But what prolly isn't commonly known is that this angle gives you a cyclic number. 360 / 126 = 2.85714.... "A cyclic number is an integer in which cyclic permutations of the digits are successive multiples of the number. The most widely known is the six-digit number 142857, whose first six integer multiples are 142857 × 1 = 142857 142857 × 2 = 285714 142857 × 3 = 428571 142857 × 4 = 571428 142857 × 5 = 714285 142857 × 6 = 857142" ~Wikipedia Then you make another one of these chopped tetras and flip it upside down and match the points and you're done. Pretty sweet... ☕🥐

LOLOLOL Wolfram's right. I know why it worked with my first attempt. Because I didn't know the angles, I just divided the side in half to get the long side and that can always be inverted. But the 72° doesn't give a half of the side. It gives more. So they don't match. Durer cheated! LOLOL

[@DarkMoonDroid]

And now his genius is truly exposed. He would have to "distort" the cube just perfectly in order to get all 3 sacred angles. So, how did he do that? I 💗 geometry.

Truly, this is a fun puzzle. I am also interested in thots on the rest of the items in the picture: The chipped millstone covered with a cloth and a putto sitting on it, writing something. The 7-runged ladder. The little thingy next to the dog. The 4 nails. The bag hanging on the Angel's belt. The directions.... Sirius has a low arc - South of the Ecliptic, the shadows seem to be showing the sun to be in the North-West, the vertical sundial seems to be on a North Wall... etc. The face on the face of the solid. So many things. Thank you for your presentation.

Work of Genius! One genius presents another.

[@gabriellachiappelli]

Great lecture! I enjoyed every minute!

[@peggyharris3815]

Fascinating presentation!

[@abrahamchavez1301]

Awsome

gracias, muy interesante

[@KuassiHounza]

Super Zhenya. Thanks for your work. Thanks. In a short time, I will be involved in the Project AWE (continuing the work of my godfather John Slifko). And I will...
