Why did strings enter the story?
Once special relativity was on firm observational and theoretical footing, it was appreciated that the Schrödinger equation of quantum mechanics was not Lorentz invariant, therefore quantum mechanics... |

This question already has an answer here:
While reviewing some quantum mechanics, I cam across a very interesting situation. For a potential barrier, if a particle has an energy $E$ less than the potential barrier $V_0$, it is possible to measure it inside the potential barrier or the classic... |

There's a campaign in the US saying that every student should have the opportunity to learn to write computer code. And I agree - it is a great thing to be able to do. However I do warn people who take that step into coding that it m... |

Faster than light or not
I don't know about the rest of the world but here in Germany Prof. Günter Nimtz is (in)famous about his display experiments that he claims show that quantum mechanical tunneling happens instantaneously rather than according to Einstein causality. In the past, he go... |

Biphoton Inspiral
The matter-energy equivalence principle shows that the energy of a photon of light is equivalent to mass and the mass of an atom therefore increases when it absorbs light. In fact, the sun's gravity bends the path of a photon just like a the sun's gravity bends the path of a pa... |
