Semiconductor Quantum Optoelectronics: From Quantum Physics to Smart Devices (Sussp Publications, 50)
fracas (Free subscription) | yesterday
The main fracas blog has… moved. The existing posts at this blog will remain here… because you just never know when someone searching for ‘women with three boobs’, ’sexy bra photos’, ‘quantum physics’ or ‘food porn’ might need to access something I’ve written in the past. Oh, you caught that, did you? Well, if you really want to find...

... The 10 weirdest physics facts, from relativity to quantum physics . Well, it looks more line none, really. But this impresses: Atoms are 99.9999999999999 per cent empty space. As Tom Stoppard put it: "Make a fist, and if your fist is as big as the nucleus of an atom, then the atom is as big as St Paul's, and if it happens to be a hydrogen atom, then it has a single electron flitting about...

An important aspect in defining a path integral quantum theory is the determination of the correct measure. For interacting theories and theories with constraints, this is non-trivial, and is normally not the heuristic "Lebesgue measure" usually used. There have been many determinations of a measure for gravity in the literature, but none for the Palatini or Holst formulations of gravity....

Last night, the BBC's popular science series, Horizon , once again featured the urbane and amusing comedian Alan Davies, in a programme entitled How long is a piece of string . Like virtually every other popular science book or programme, it is also reiterated the following interpretation of quantum theory: A particle can be in two different places, A & B, at the same time , This is a claim repeated...

I wish that Julian Voss-Andreae had made some of these sculptures when I was in school. While we can't really claim that they represent quantum physics concepts accurately, they still would've made reading about Bosons and Fermions more pleasant. Julian left his quantum physics research path, but he certainly carried knowledge and inspiration from it over into his art career. These sculptures are...

The essentials of quantum theory, the Schr\"odinger equation and the Planck constant, are derived using classical statistical mechanics within the non-local Machan model. The appearance of complex wave function is connected with the necessity of quantization condition when one neglects the existence of the preferred frame and assumes Galilean symmetry of the model.

Quantum physics says: “If noone is observing an object, it does not exist”. I say, thank goodness God exists then! If he wasn’t watching the whole universe all the time, parts of it would stop existing. Crazy physicists.

Just watched a great TV programme about the length of a piece of string, a neat device to introduce quantum physics. The ideas are simply mind-blowing. Light can be anywhere at once. We only see it because we are here. Everything is here and not here simultaneously. I think therefore I sink. I need a drink!

"Father" from the series "Spin Family (Bosons and Fermions)" 2009, steel and silk, 7" x 6" x 6". We've posted previously about physicist, software designer, and artist Julian Voss-Andreae whose work lies at the intersection of science and sculpture. Last year, he created a massive metal protein sculpture linked to Leonardo's Vitruvian Man. Now, Julian has made 30...

It appears that there's a new independent movie titled "Triple Hit" that is making use of various popularization of quantum mechanics. The film - previously called Schrodinger's Girl - centres on Rebecca Hunter, a disgraced scientist conducting research into alternate universes. She discovers a way to travel between realities and then finds her parallel-world counterparts have their own agendas:...

With all due respect to ALL other theorists...IMO alot of the theories are way to complicated. Ex. Quantum theories, doubles or doppelgangers in ALT timelines--diverging and converging, Time Machines, etc. And "Whatever Happened, Happened" and "Dead Is Dead" which both ep titles were uttered by Ben, which is immediately suspect and impossible, for me, to hang any theory on. Info...

What's new since the last post? I've finished taping the new course for the Teaching Company . Now all I have to do is finish the written materials -- a big job that I'm behind on, true, but a little less of a crisis. The course should be a fun one. A total of four " Friday Afternoon Physics " videos are up, including my favorite, Episode 4 (in which we blow things up). Episode 3 is on quantum...
