Was Newton right and Einstein wrong? It seems that unzipping the fabric of spacetime and harking back to 19th-century notions of time could lead to a theory of quantum gravity. Physicists have struggled to marry quantum mechanics with gravity for decades. In contrast, the other forces of nature have obediently fallen into line. For instance, the electromagnetic force can be described quantum-mechanically...

When asked what his Third Symphony meant, Ludwig van Beethoven is said to have sat down at the piano and begun playing it. Analogously, a physicist might write down Erwin Schrödinger's wave equation as an 'explanation' of quantum theory. But even this formula was Schrödinger's

An Englishman, an Irishman, a Scotsman and a Giant are all standing around talking about Quantum Physics. The Englishman says "Once Cern is working properly, everything will change". Just then a plane flies past and distracts the Giant, and when he turns back to continue the discussion, he realises he is all alone. Two Giants walk into a pub. The first one says to the Bartender "Where've...

On the subject of Quantum Physics, I tell you what annoys me. Animal rights people complaining about animal abuse in reference to Schrodinger's cat. Firstly it is a theoretical paradoxical thought experiment that neatly demonstrates the idea of quantum superpositions. More importantly, don't they realise that by opening the box to rescue the animal they are observing it's state which will collapse...

The great 'global warming' hoax BY: Roger Hedgecock While all eyes focus on the unfolding drama of the "health-care reform–health-insurance reform–jobs bill," another critical part of the "Change America" plan just took a torpedo midships. Some 1,000 e-mails and 3,000 documents from the Climate Research Unit at the U.K.'s University of East Anglia (where the "world's...

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.
