As a visual artist that works in geometric shapes I loved this. I have seen a talk about quasicrystals in Islamic art quite a while back, (possibly it was this one), and was amazed at the interrelations. I especially enjoyed Mr. Lu's method of explaining this. For me it was quite understandable. Thank you.
This was a great lecture. I watched a lecture by Penrose on the topic of Crystalline patterns where he spent barely 15 seconds on Medieval Islamic architecture!
Amazing lecture, thank you for sharing this. This increased my knowledge of Islamic art, and also shed some light on linear algebra and matrices - something I have been puzzling over. Can you tell us what questions were asked in the last few minutes please? Not the controversial one, but the one or two that prompted you to comment on muqarnas and the geometry of curved space.
Every single image you present is an example of periodic tiling. Where are the quasicrystals? Correct me if I'm wrong, but the curvy Penrose lines you put on your Girih tiles are necessary but not sufficient to enforce a legal aperiodic tiling out to infinity. For legal aperiodicity you would need to integrate Amman lines, right? Anyways, the presentation is intriguing in and of itself. Good work.
Albert Einstein's paper for Mercury is invalid because two roots of one equation are imaginary numbers. Click on "67. Error In Einstein's Calculation Of Perihelion For Mercury" on this website. sites.google.com/view/physics-news/gravitation
Thank you very much Dr. Lu! A beautiful presentation with fascinating and deep geometry! The link to your webpage peterlu.org doesn't seem to work though.
13:24 Actually I didn't see the rhombus and the pentagon in there. I'm hoping that he goes into this further later, because I'm making these and I want the full set.
Pisagorians dont share " knowledge " with "ordinary man" ,after that ,Islam Sufi scientist also follow same way and find a way to communicate with symbolic language , Question is that : If Mediaval Islam Sufi scientist " saw " this crystals 1000 years ago , WHY THEY DİDNT SHARE other DATA after that
They aren't Islamic. They all originated in Persia long before Islam, and spread to other places. These patterns are closely related to weaving especially carpet weaving and patterns, which are mainly plant form geometrical abstractions.
I wish you didn’t have to reply with what faith you have. Talking about faith, if God created Math and Geometry then being Christian or Muslim shouldn’t matter... just that you open your mind to His creation with faith. I loved an unbiased interpretation of Human endeavor... inspired by what cannot be the reason of any bias in discovery...
Great! but i miss the connection between The Great Central Sun, the 24 elders, the TRONE, and the Qrystalgrid structure of the Nectar of Creation. All the platonic body s crystalized structures above and below, are the highroads of your spirit.we are ARCHITECT, and create with 13 megasnares holographic realitys in the eather..All is AETHER, all is thoughts and intensions, all is architected by the ONE great spirit, Great central sun, home of the soul is architect of all CRYSTALSTRUCTURES WE SEA.
