The discovery of quasi-crystals by Prof. Danny Shechtman has implications for chemistry, physics, materials engineering and even art

Prof. Dan Shechtman from the Faculty of Materials Engineering at the Technion won the 2011 Nobel Prize in Chemistry for the discovery of quasi-crystals.
In quasi-crystals we find a demonstration of the puzzles painted on the walls of mosques replicated at the atomic level: regular patterns that do not repeat themselves. However, the configuration found in quasi-crystals was considered impossible, and Daniel Shechtman fought a hard battle against established science. The 2011 Nobel Prize in Chemistry is dedicated to the way chemists see solid matter.
It was on the morning of April 8, 1982, an image that contradicted the laws of nature appeared in Dan Shechtman's electron microscope. In solid materials the atoms are packed in crystals in symmetrical patterns that repeat themselves cyclically over and over again. For scientists, this repetition is part of the definition of a crystal.
The image Schechtman saw under the microscope showed that the atoms in his crystal were packed into a pattern that could not be repeated. Such a pattern was considered impossible because it creates a sort of football consisting of only hexagonal patches, where the configuration requires alternating tentacles and hexagons. His discovery was controversial. During the need to defend his findings he was forced to leave the research group where he worked, but ultimately his battle forced scientists to rethink their perception of the nature of matter.

It is recommended to read about Penrose tiling (of which quasi-crystals are a three-dimensional generalization) and see where the golden ratio comes from.
Search for the word golden on this page: http://en.wikipedia.org/wiki/Penrose_tiling
And by the way - any place where many pentagrams are "played" is a place where the golden ratio appears many times.
I don't know if quasi-crystals have been discovered or exist in principle that are not based on pentagons on any scale, but:
1. If there is not - then the origin of the golden ratio is clear
2. If there is - then probably the golden ratio will not be found in them either.

Why would they succeed if they didn't try?
Why would they try if in practice this is not the case?
Not every place where the golden ratio appears the Fibonacci series is shown.
These days I am teaching the students (XNUMXth grade) about the order in the crystal structure - graphite, diamond, fullerene, graphene...
Then comes Prof. Shechtman's discovery showing that it is possible to observe the arrangement of atoms from an interesting point of view that challenges the existing concept (the story of the rise and fall of paradigms)
I agree with the chemistry student, indeed the number of Israelis who receive a Nobel Prize (for science) is on the rise!
And now to the statistical question: What is the ratio between the percentage of Jews in the world and the percentage of Jews receiving the Nobel Prize? (scientific fact)
And what are the possible explanations for this? (theory)
Chemistry student - what a genius you are.
Kudos to you for raising your opinion that Prof. Shechtman deserves a Nobel Prize.
If you hadn't said it we wouldn't have known
I wonder if he will win an award?
Congratulations to Prof. Shechtman from the Faculty of Materials Engineering. Amazing achievement! Well done!
Once again, statistical proof is given that the Wolf Prize predicts receiving a Nobel Prize
For 1 the chemistry student: the universities have become more efficient,
They pay the cleaning workers starvation wages (through contractors of course)
Agree with a chemistry student. I said yesterday that this is a poverty certificate for Israel and now I swallow my hat.
I am ready to eat a lot of hats, shoes and other spare parts so that there will be more Nobel Prize winners in Israel.
thanking! Yeruham thanks and leaves.
All the best to Prof. Shechtman.
And yes, it will not hurt the universities to become more efficient and the government to increase their budgets.
And the bottom line - how much how much?
Meanwhile, the Jews against the world in this round is 7 out of 7, isn't it?
I wonder if they were able to explain why these crystals are always arranged according to Fibonacci patterns.
What causes the various arrangements to obey this Fibonacci series precisely.
Awww! This is a discovery that deserves a Nobel Prize!
Congratulations to Prof. Shechtman, the Technion, and the State of Israel!
And to all those who said yesterday that this is a poverty certificate for the State of Israel,
That so many Jews win and there are no Israelis, swallow your hat.
Of course, it would not hurt the government to increase budgets for universities
And the universities themselves would not hurt to become more efficient.
