aaa69ca20d2a0882 | If You Can’t Make Predictions, You’re Still In A Crisis
Is psychology in the midst of a research crisis?
When physicists discovered that subatomic particles didn’t obey Newton’s laws of motion, they didn’t cry out that Newton’s laws had “failed to replicate.” Instead, they realized that Newton’s laws were valid ... |

Non Local SETI
Discussing this issue five years ago with some colleagues about SETI I extensively answered as follows.
<< Concerning quantum entanglement, it is an ascertained reality when two particles have first interacted together and then are separated even at the longest distanc... |

Nuclear structure
At the center of every atom lies a small, dense nucleus, which carries more than 99.97% of the atomic mass in less than 10-12 of its volume. The nucleus is a tightly bound system of protons and ne... |

57dabef9d7f6f1fe | Problems of Quantization of General Relativity
In some sense, there does not exist a problem of "quantization of gravity". The quantization of Newtonian gravity is, in particular, a triviality. One can more reasonably talk about a problem of "quantization of relativistic gravity". But, in fact, this problem is also an... |
