very encouraging article here about the crystal Perovskite and its use for a cheaper electrical solar panel http://www.technologyreview.com/news/517811/a-material-that-could-make-solar-power-dirt-cheap/ ; but the ball and strut graphics of crystal lattices shows how complicated it can get. see http:...

i enjoyed listening to Henrik Palmgren and Scott Onstott have a conversation about measuring, shapes and spatial relationships, here on the glorious swedish fountain of red ice http://www.redicecreations.com/radio/2013/08/RIR-130802.php ; " Scott Onstott - Hour 1 - Explorations in Number, Architectu...

RobertW-- i think it would be something like listening to a 4 cycle gasoline engine, you can hear when it become stable, and if it cannot achieve that speed, you can hear that it is unstable. as to why the merkaba would be unstable at slow speed, it is like a top, for any given height and width & ma...

Thanks for your explanation, Guy. i'm still left wondering about the distribution of mass as the tetrahedrons wobble and bobble around each other in a merkaba. of course, on average it would all even out, but it seems intuitive that at any given instant and at a fixed point within the volume of spac...

this is just wonderful!!! http://s254.photobucket.com/user/Heinzzweidrei/media/p-dodek2a_zpsc78b668b.jpg.html ; is it a real model?? do you still have it? could you take more pictures/photos so i could see it from more angles? the bottom right pent is confusing me. is it a pent? it's gorgeous.

perhaps this is the merkaba you mentioned, as inside the cube

I am sorry, Ulrich. i just do not see how this could be. i think you are saying this: look at the pair of blue pins that are strictly vertical and there are 4 gold balls on the vertical blue pins. the top and bottom balls are clearly on the apex/zenith of the merkaba, and on the base or nadir. but t...

Hello Ulrich,

sorry i haven't been in to reply more quickly. It's been over 100'Fah here this week; today 105, and apparently my brain shuts off about about 90.

but i'll be back in to clarify what i think i am seeing in your merkaba with the many pins.

thanks for the drawing.

katie.

i'm sorry i derailed the conversation we were having about merkaba representations. this .gif is really very close to a planar image of a merkaba when viewed from above the axis of rotation. 3-foldkr.gif @ http://i254.photobucket.com/albums/hh82/Heinzzweidrei/3-foldkr.gif ; what is important about t...

Sorry not to respond Guy---for some reason, i did not see a notification of your recent post. and for some reason, the image you posted is not displaying, and i cannot see it. i was coming here to post a link to something that must be considered as a sacred geometry, which is the physical manifestat...

Ulrich, your garden of shapes is exquisite. it is amazing that you could make these beautiful and so complicated shapes, and keep them true and correct. i am amazed. i think if you keep this in a protected spot in a garden, near a tree, it would be a perfect place for a garden fairy to live. http://...

i love that little icosahedron, i found for my icon, and i wish i could keep it in my head, but so far, i cant keep the 12 sides together, it just falls apart. pentagrams, as far as i have read, have the greatest potential for self-defense. and i like them very much for that. i found this site origi...

hurray!!

isn't that an extraordinary shape. i've been puzzling over it.

can someone try to make it a 3d shape in stella, please.

i'll have to try again.
