How to tell science from pseudoscience
Is the earth flat? Is 5G is a mind-control experiment by the Russian government? What about the idea that COVID was engineered by the vaccine industry? How can we tell apart science from pseudoscience? This is what we will talk about today.
Now, how to tel... |

Magic number
In nuclear physics, a magic number is a number of nucleons (either protons or neutrons) such that they are arranged into complete shells within the atomic nucleus. The seven known magic numbers as of 2007 are:
2, 8, 20, 28, 50, 82, 126 (sequence A018226 in OEIS)

On the Interaction of Ultra-short Laser Pulses With Human Brain Matter
J. Marciak–Kozlowska and M. Kozlowski
In this paper the modified Schrödinger equation for the interaction of attosecond laser pulses with “atoms” (neurons) of the human brain is developed and solved. Considering that the mas... |

No, We Don’t Need to Slow Down Moore’s Law

Quantum mechanics consists of the breakthrough in physics in the 1920s in understanding how particles behave inside atoms. Classical mechanics, as initially discovered by Isaac Newton, cannot explain atomic behavior. Erwin Schrödinger is g... |

Edit 26/Sept/13: Fixed Typo in potential
I'm solving the following (seemingly simple) quantum-mechanical problem in four spatial dimensions. In natural units ($\hbar^2/2m=1$), the Schrödinger equation reads:
$$ \Big[-\nabla^2-\frac{24 R^2}{(\mathbf{x}^2+R^2)^2}\Big]\psi(\mathbf{x})=E\,\psi(\... |

Illusions of Theories of Everything
The ultimate dream of theoretical physicists is a Grand Unified Theory GUT or a Theory Of Everything TOE as a mathematical equation in the form of a system of partial differential equations, the solutions of which would represent all there is in the World. W... |

"The Volatility Smile" - a first impression
I always do this.
I'm casually scanning the Amazon Vine list, scrolling past beauty aids and iPhone covers when I come across "The Volatility Smile".
What kind of title is that? A detective story with a Japanese print on its front cover?
OK, it'... |
