Dark Matter and Living Matter
Dark matter and living matter represent two deep mysteries of the recent world view. There however exists an amazing possibility that there might be close connection between these mysteries.

Virtually all my research, which is still continuing actively, has been based on the conviction that time, motion and size are all relative. I call this the relational approach. My main collaborators for the earlier work were Bruno Bertotti, Niall Ó Murchadha, Edward Anderson, Brendan Foster, and Bryan... |

90f36812dea1d718 | ONE hundred years ago this month, a light-bulb lit up over a physicist's head—and he wondered what made it yellow. For, while the yellow colour of a bulb suggests that it is giving off most of its light at that easily visible frequency, the physics he had been taught predicted that a heated object should emit mostly sh... |

Thermodynamics is the study of the various properties of macroscopic systems that are in equilibrium and, particularly, the relations between these various properties. Having been developed in the 1800s before the atomic theory of matter was generally accepted, classical thermodynamics is no... |

A heterojunction is an interface that occurs between two layers or regions of dissimilar semiconductors. These semiconducting materials have unequal band gaps as opposed to a homojunction. It is often advantageous to engineer the electronic energy... |

Furthermore, not all parts of the theory are fully fleshed... |

Classical physics, the body of physics developed until about the turn of the 20th century, cannot account for the behavior of matter and light at extremely small scales. The branch of physics concerned with atomic and subatomic systems is known as quantum mechanics. Its aim is to account ... |

Is There Dark Matter in Orbit around the Earth?
By Stephen L. Adler Published 2009
The earth flyby of the asteroid-lander NEAR spacecraft resulted in an unexplained velocity increase of over one centimeter per second, much larger than estimated measurement errors.
For slightly over a year, I have larg... |
3aa595bf8c494afb | All quantum operations must be unitary to allow reversibility, but what about measurement? Measurement can be represented as a matrix, and that matrix is applied to qubits, so that seems equivalent to the operation of a quantum gate. That's definitively not reversible. Are there any situations where non-unitary gates m... |
