Quasicrystals in Medieval Islamic Architecture, Harvard Physics Colloquium Lecture

[@beckapick1343]

Thank you so much for giving the credit back to the Islamic architects.

[@2000sborton]

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.

[@rmschindler144]

an excellent talk; I love this stuff: it calms me right down, and makes space for the best in me to play & emerge.

[@tauseefakbar6413]

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!

[@NejiBHTahar]

What a magnificient presentation! Thank you.

[@rezaulreza3979]

Many many thanks Peter Lu for your analytic presentation......

[@blindguysuckatgaming1376]

just seen this guy today in a lecture. i was fascinated. thank you mr peter lu .great presentation

[@skyrocket8519]

I come back to this lecture every year or two, thanks Peter.

[@captainTubes]

Riveting! I deeply enjoyed your work on the compound machine, and corundum axes as well. Thank you so much for sharing here.

[@kummer45]

I use these lectures to construct my patterns in Grasshopper 3D. A lot of explanations are in detail here.

[@SmedtheSDOTakayoyo]

Very interesting. I am only an amateur tesselator - in high school -but I find your research incredibly analytical

[@samiramian]

Excellent work lecture... thank you Peter Lu.

[@abdulqutub5015]

looking for answers in unexpected places is what gets you ahead in the scientific community.

[@amberslahlize7961]

Just because you're primitive, doesn't mean you are stupid!

[@kalcidis]

Fantastic lecture. Thanks for the upload!

From Islamic geometry to tiling to cooking pan. Humans have come a long way.

[@MuslimAlchemy]

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.

[@truebomba]

How to produce such an elegant presentation with all that beautiful animations ?

[@dipu6174-t8n]

Mind blowing lecture.

[@DRSulik]

Consider publishing this with sound?

[@innokentiyromanchenko1450]

everyone who hear squeak - cut out 16 above on equalizer, helps a lot

[@SaveSoilSaveSoil]

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.

42:50 I felt like I was in a rap battle and someone dropped a great punchline.

[@PrototypeOnDemand]

this post was SICK ! very helpful

[@AhmedArtsCalligraphy]

wow, am completely blown away by this amazing lecture, many thanks for sharing.

[@DarkMoonDroid]

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.

[@humairagowher5539]

Excellent presentation!

[@bens4446]

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.

[@scottstensland]

excellent book : ... The Second Kind of Impossible by Paul J Steinhardt ... Princeton Prof

[@menzeliano]

min 6 and already love the dude

[@etiennejansen3110]

Fantastic lecture ! Thanks.

[@TuhinOliuddin]

It's a lecture delivered in future ! :) Look at the date at the bottom right corner- December 3/2017.

[@oo0olegendoo0o]

see your optomitrist

[@gmailgmail3222]

Tuhin Oliuddin open your eyes widely

[@inocuousaltaccount3103]

how did i get here

[@BOBMAN1980]

Thanks so much for this!

[@wafamir2010]

Fascinating.

[@samk8890]

very good research

[@aminathedesigner]

So easy to understand it. Thank you so much for nice lecture.

[@London_miss234]

Great lecture

Very good

[@HarperLeich]

awesome!

[@kabeemer]

amazing...

[@bluetrinityhaloseven7244]

yes they had very little clue what the spirit molecule was back then...even though they obviously used it every night when they dreamed...haha.

[@Neutron-Notron]

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

[@soupytho]

Fav!

[@kayem3824]

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.

[@kayem3824]

@يا سين No evidence at all.

[@amonali1464]

It is Islamic because Islam gave a challenge to Artist they should not use human or animals faces so they started to use shapes

[@saudigirl5304]

Loool !! How is that

[@machoprotegido5607]

In Islam you make errors on purpose (rugs, tiles...) to emphasize that only God does things perfectly.

[@craft-sa8708]

واو

[@humairagowher5539]

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...

[@mysticsun888]

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.
