An updated and renewed version is available at: This is a web site for young students - and anyone else - who are (like me) thrilled by the challenges posed by real science, and who are - like me - determined to use their brains to discover new things about the physical world that we are living in. In short, it is for all those who decided to study theoretical physics, in their own time. It so often happens that I receive mail - well-intended but totally useless - by amateur physicists who believe to have solved the world. It should be possible, these days, to collect all knowledge you need from the internet. I can tell you of my own experiences.
Theoretical Physics is like a sky scraper. 'Schrödinger's hat' could spy on quantum particles. An international team of physicists has proposed a new device that could detect the presence of waves or particles while barely disturbing them.
Called a "Schrödinger's hat", the device has not yet been built in the lab but the team believes that it could someday be used as a new type of sensor for quantum-information systems. In the microscopic world of quantum mechanics, direct observation of the property of a particle – the position of an electron, for example – causes the collapse of the particle's wavefunction. The result is that the particle that you set out to measure has been changed in a significant way. In the early 1990s, physicists Avshalom Elitzur and Lev Vaidman at Tel Aviv University in Israel pointed out that it is not always necessary to observe particles directly to learn something of their nature. The researchers imagined a pile of bombs, each of which is designed to be triggered by the absorption of a single photon. Untitled.

8 shocking things we learned from Stephen Hawking's book. From the idea that our universe is one among many, to the revelation that mathematician Pythagoras didn't actually invent the Pythagorean theorem, here are eight shocking things we learned from reading physicist Stephen Hawking's new book, "The Grand Design," written with fellow physicist Leonard Mlodinow of Caltech.
The book, covering major questions about the nature and origin of the universe, was released Sept. 7 by its publisher, Bantam. 1. The past is possibility According to Hawking and Mlodinow, one consequence of the theory of quantum mechanics is that events in the past that were not directly observed did not happen in a definite way. Instead they happened in all possible ways. This is related to the probabilistic nature of matter and energy revealed by quantum mechanics: Unless forced to choose a particular state by direct interference from an outside observation, things will hover in a state of uncertainty. Yeah, we're still trying to wrap our brains around this. 2. 3. 4. 5. Professor of Theoretical Physics, CUNY.
