Quantum mechanics (QM – also known as quantum physics, or quantum theory) is a branch of physics which deals with physical phenomena at microscopic scales, where the action is on the order of the Planck constant. Quantum mechanics departs from classical mechani... |

Constant torque as a manner to force phase transition increasing the value of Planck constant
The challenge is to identify physical mechanisms forcing the increase of effective Planck constant heff (whether to call it effective or not is to some extent matter of taste). The work with certain... |

7efa10a15af89c80 | New Physics Theory Resolves Paradoxes
For 100 years, most people have found it impossible to understand physics. Examples include Joseph Heller (“writhing in an exasperating quandary over quantum mechanics”), Bill Clinton (“I hope I can finally understand physics before I leave the earth”, Richard Feynman (“One had to... |

On the Pierrehumbert thread, I stated:
So, if you have followed the Climate Etc. threads, the numerous threads on this topic at Scienceofdoom, and read Pierrehumbert’s article, is anyone still unconvinced about the Tyndall gas effect and its role in maintaining planetary t... |

I know it’s a crazy title. It has no place in a physics blog, but then I am sure this article will go elsewhere. […] Well… […] Let me be honest: it’s probably gonna go nowhere. Whatever. I don’t care too much. My life is happier than Wittgenstein’s. 🙂

Frank Wilczek: Ugly Answer to Ugly Question
In his new book A Beautiful Question: Finding Nature's Deep Design, Frank Wilczek (Nobel Prize in Physics 2004) starts out stating the questions (or paradoxes) which motivated the development of modern physics:
In the quantum world of atoms and light, N... |

FQXi essay contest 2014: How Should Humanity Steer the Future?
This year’s essay contest of the Foundational Questions Institute “How Should Humanity Steer the Future?” broaches a question that is fundamental indeed, fundamental not for quantum gravity but for the future of mankind. I suspect ... |

This spring, there was excitement in the world of physics as a long-predicted butterfly was proved to exist. But, being a creature of physics, this butterfly wasn’t an insect, nor anything that would even occur without human minds to construct it.
This was Hofstad... |

Algorithm wars
Some tantalizing Renaissance tidbits in this lawsuit against two former employees, both physics PhDs from MIT. Very interesting -- I think the subtleties of market making deserve further scrutiny :-)
