Roger Penrose - Forbidden crystal symmetry in mathematics and architecture
Roger Penrose - Forbidden crystal symmetry in mathematics and architecture
Sir Roger Penrose provides a unique insight into the "forbidden symmetry" of his famous penrose tiles and the use of non-repeating patterns in deisgn and architecture. It is a rigorous mathematical theorem that the only crystallographic symmetries are 2-fold, 3-fold, 4-fold, and 6-fold symmetries. Yet, since the 1970s 5-fold, 8-fold, 10-fold and 12-fold "almost" symmetric patterns have been exhibited, showing that such crystallographically "forbidden symmetries" are mathematically possible and deviate from exact symmetry by an arbitrarily small amount. Such patterns are often beautiful to behold and designs based on these arrangements have now been used in many buildings throughout the world. In this Ri event Sir Roger Penrose reveals the mathematical underpinnings and origins of these "forbidden symmetries" and other related patterns. His talk is illustrated with numerous examples of their use in architectural design including a novel version of "Penrose tiling" that appears in the approach to the main entrance of the new Mathematics Institute in Oxford, officially opened in late 2013 (http://www.maths.ox.ac.uk/new-building). The tiling is constructed from several thousand diamond-shaped granite tiles of just two different shapes, decorated simply with circular arcs of stainless steel. The matching of the tiles forces them into an overall pattern which never repeats itself and exhibits remarkable aspects of 5-fold and 10-fold symmetry. Similar features have been found also in the atomic structures of quasi-crystalline materials. The initial discovery of such material earned Dan Shectman the 2011 Nobel Prize for chemistry, his work having launched a completely novel area of crystallography.

Roger Penrose: Dal Big Bang all'eternità, Cycles of time: An extraordinary new view of the universe
http://www.festivalscienza.it http://gabrielemartufi.altervista.org Dal Big Bang all'eternità. I cicli temporali che danno forma all'universo Cycles of time: An extraordinary new view of the universe Sir Roger Penrose è un fisico matematico inglese, Emeritus Rouse Ball Professor of Mathematics al Mathematical Institute dell'Università di Oxford e Emeritus Fellow al Wadham College. È uno dei più grandi pensatori dei nostri tempi e nel 1988 per i suoi studi sulla struttura dell'universo ha ricevuto il premio Wolf (Wolf-Prize) per la fisica, insieme a Stephen Hawking. http://it.wikipedia.org/wiki/Roger_Penrose Intervista/Interview Perché crediamo nel Big Bang? Perché abbiamo delle prove: le galassie che si allontanano, l'espansione dell'Universo. Qualcuno ha scoperto la radiazione di fondo a microonde, che viene da tutte le direzioni ed è 3,7 gradi sopra lo zero assoluto. Ovvero, il lampo del Big Bang che si è raffreddato: questa ne è l'evidenza diretta. Ma l'ipotesi di questo modello cosmologico standard, secondo il quale l'Universo nato dalla grande esplosione è destinato a espandersi in eterno e a raffreddarsi sempre di più, non è l'unica strada. Secondo altri studi non c'è solo un Big Bang, ma anche un grande crunch (Big Crunch). Da tenere in conto, c'è anche l'entropia: per la seconda legge della termodinamica, l'entropia aumenta con il tempo. Dunque, la casualità aumenta. Il paradosso è che nel momento del Big Bang si ritiene che l'entropia fosse già al massimo grazie alla curva di equilibrio termico. Eppure, teoricamente se si torna indietro nel tempo c'è meno entropia. Se l'entropia era già al massimo, come può aumentare di più? L'elemento fondamentale da prendere in considerazione è la gravità. Siccome l'Universo attrae, aumenta l'entropia e le stelle formano un agglomerato, che dà poi origine a un buco nero. È così che l'Universo è diventato più casuale. Ma la natura speciale del Big Bang sta nel fatto che la gravità nelle prime fasi non era attivata. Se si risale nel tempo al Big Bang, la temperatura diventa via via più calda e a un certo punto la massa diventa completamente irrilevante. Allora la geometria è una geometria conforme e non quella di Einstein. Dunque non è più una singolarità. Nell'ipotesi di un Universo in perenne espansione, tutto diventa molto noioso, e possiamo ipotizzare solo piccole esplosioni. Ma forse l'Universo è una sorta di loop? Si può tornare indietro nel tempo? Ci sarà un altro universo dopo il nostro e ancora e ancora all'infinito? Per quale motivo crede che la nostra coscienza il nostro pensiero non sia ripetibile, simulabile all'interno di una macchina? La coscienza è qualcosa che mi ha sempre interessato molto: mio padre si occupava di malattie mentali, una materia che dunque era di un certo interesse nella mia famiglia. Quando mi trovavo nel mio primo anno di università, stavo facendo matematica pura e seguivo corsi di fisica quantistica e cosmologia così per divertimento. Durante un corso di logica matematica ho imparato i teoremi di incompletezza di Kurt Gödel e le teorie di Alan Turing. Mi fu immediatamente chiaro che capire ciò che è vero in matematica non è necessariamente governato da regole. Qualunque regola si stabilisce, si può infrangere questa regola. Se accetti le regole, ti rendi conto che puoi andare oltre. Io devo seguire delle regole e accettarle, ma Gödel dice no se accetti queste regole, devi accettare anche le altre! Che vanno oltre le tue regole. La mente, il capire non può essere rinchiuso in queste regole computazionali. La penso così da molti anni pur rimanendo una persona che crede che tutto quello che succede nella nostra testa abbia a che fare con le leggi della fisica. Non esiste qualcosa al di fuori di queste regole. Ma cos'è la fisica? Se la fisica segue le regole computazionali, allora sono vincolato, ma se c'è qualcosa di più nella fisica, allora forse quel qualcosa in più è dentro la nostra testa. Il più grande buco di comprensione che abbiamo è sicuramente nella meccanica quantistica; non perché sia misteriosa o troppo difficile da comprendere. La meccanica quantistica è di base inconsistente. Si può seguire una regola. Ma puoi immediatamente cambiare e seguirne un'altra completamente diversa. Ogni volta che cerchi di fare misurazioni tutto cambia. E io mi dicevo come puoi cambiare le regole durante il gioco, a casa mia questo si chiama barare! Non è difficile da capire è incoerente e con il mio background da matematico non mi piace molto l'incoerenza, per questo mi sembrò all'epoca che la fisica quantistica non fosse la risposta finale. Mi gratificò molto il fatto che altri pensatori oltre ad Albert Einstein hanno creduto che la meccanica quantistica non fosse l'ultima risposta e che c'era bisogno di qualche miglioramento. L'intelligenza non può essere presente senza capire. Nessun computer ha alcuna consapevolezza di quello che fa. (Roger Penrose)- published: 05 Jan 2014
