This page is about computability of fundamental physics in the sense of computable mathematics and constructive analysis. It is not about computational physics, though of course there is a relation. For computational complexity theory in physics see at computational complexity and physics.

atom711by Quentin Ruyant
One of the main tasks of philosophy is to clarify conceptual problems and sketch the landscape of possible solutions to these problems. Of course, individual philosophers often tend to defend specific positions, but what emerges at the level of the com... |
a2ccffccdc359350 | Major Concepts
Concepts add up and make up much of what John Searle called the “background”. He recognized, like others before him, e.g. Quine or Wittgenstein, that making sense of the world can’t be based just on the actual empiric “impressions” (data, if you like), but rather that we need concepts that in turn are e... |

Part 19: Four integrals defining the 4D complex number tau.
It is a bit late but a happy new year anyway! In this post we will do a classic from the complex plane: calculation of the log of the first imaginary unit.
On the complex plane this is log i and on the complex 4D space ... |

It is often said that the size of the hydrogen atom is two Bohr radii, or approximately 1 Å. However, the electron is not at a constant distance from the nucleus; all the information we can obtain from the Schrödinger equation, is... |

Quantum theory governs the universe at its most basic level. In the first half of the 20th century physics was turned on its head by the radical discoveries of Max Planck, Albert Einstein, Niels Bohr, Werner Heisenberg, and Erwin Schroedinger. An entire new logical and mathematical foun... |

Octonions and quantum physics
Peter Woit reports in "This Week's Hype" string model hype about classical number fields, in particular the possible role of octonions. It would be nice to write a comment and tell how elegantly classical number fields appear in TGD framework and make dual descript... |

Schrödinger equation
In quantum mechanics, the Schrödinger equation is a partial differential equation that describes how the quantum state of a physical system changes with time. It was formulated in late 1925, and published in 1926, by the Austrian physicist Erwin Schrödinger.[1]
