Constructions géométriques et nombre d'or

1 Upvotes

Je suis à la recherche de constructions géométriques (sous GeoGebra éventuellement) dans lesquelles le nombre d'or apparait très incidemment (pas de division harmonique , pas de pentagone , d'angle multiple de 18° ….)

Actuellement je n'en ai regroupé que trois :

- Dans un rectangle ABCD , où placer M sur AB et N sur BC pour que les triangles DAM , MBN et NCD aient même aire. PartageTerrain – GeoGebra

- Construire un triangle isocèle AB = AC = 1 tel que l'aire de son cercle inscrit soit maximum. Cercle max – GeoGebra

- Sangaku Angles égaux – GeoGebra

Si vous en avez d'autres même partielles , je suis très intéressé.

A 50k lattice points per axis 2D structure added to the Complex Lattice Topology database, CLT. Rendering lattice points around the 20 nm range will allow metasurface production covering one square mm in a single pass, without stitching using electron beam lithography, and be in the blue end of the optical spectrum. Sample image a 2k by 2k section.

The sqrt(14)-leaper (1,2,3) on signed permutations of (1,1,1) and (0,1,2) makes a sextic graph in the fcc lattice.
The 3-leaper on the 4×4×4 cubic lattice makes a sextic graph. (Grabarchuk)
The 5-leaper on the 8×8 lattice makes a quartic graph.

While there is hype for 3-body problem, for 2-bodies it is already extremely interesting if adding spinning of one body/its magnetic dipole moment. Intro with derivation, animation and code: https://community.wolfram.com/groups/-/m/t/3522853

Free tool for 3D geometry?

Dear community, I have defined a set of irregular tetraedra that I think will join interestingly in space, do you know any free and easy tool to model them for testing?

it uses a modified 4x5 version of the phizz unit when it intersects itself, which turns the surface inside out (sorta cheating)
