Sustainable development requires human ingenuity. People are the most important resource.

My childhood dream was to study mechanical engineering. After reading 'The Mysterious Island' - which I read 25 times as a boy - I thought that was the best thing a person could do. The engineer in the book knows mechanics and physics, and he creates a whole way of life on the island out of nothing. I wanted to be like that.

Young people in Israel are encouraged to design, produce and sell their products from high school. Technical universities also matter. Teach and introduce entrepreneurship courses in technical universities.

I see the root of the education crisis in the primary and secondary schools. Academia is doing a fairly good job. The root of the problem is the teachers. Some are great. But too many of them are not capable of being good role models. They can't control the classes. They lose too much time trying to create a learning environment.

The good news is world population growth rate decreases systematically and is expected to reach zero by 2050, thanks to urbanisation and women's education.

The good people look for challenges. When teaching becomes a prestigious profession, then you'll get good people.

A president should look for what binds the people together rather than what drives them apart. As soon as you are identified with one side of the political map, you are no longer everybody's president.

Crystallographers believed in X-ray results, which are of course very accurate. But the x-rays are limited, and electron microscopy filled the gap, and so the discovery of quasicrystals could have been discovered only by electron microscopy, and the community of crystallographers, for several years, was not willing to listen.


Select a subject that interests you and make an effort to become an expert in that field. I promise you, if you make the effort, and you become an expert, you will have a wonderful career.

On April 8, 1982, I was alone in the electron microscope room when I discovered the Icosahedral Phase that opened the field of quasi-periodic crystals.
