Interferometric gravitational wave detectors are amongst the most sensitive instruments ever built. They are hunting for tiny oscillations in space-time originating from cosmic events such as inspiraling objects or supernova explosions. These detectors are based on Michelson-like interferometers reaching sensitivities for lengths changes of better than

The article discusses tool use in fish, adapted from the book "What a Fish Knows: The Inner Lives of Our Underwater Cousins, by Jonathan Balcombe, including in regard to cognition in fishes. An overview of tool use by the orange-dotted tuskfish (Choerodon anchorago) to break a clam and by the archerfish's (Toxotes') squirting water in its predation of ...

The Einstein Action and the Einstein Equation
2019We start by defining the notion of Riemann tensor and curvature, and positive and negative curvature spaces. We then show how to turn a special relativistic invariant theory into a general relativistic invariant one and write down the Einstein–Hilbert action for gravity, based on Einstein's principles and on matching with experiment. We then derive its

Nature, 2005 Scientific celebrity has a relativity all of its own. Some scientists are celebrated by their peers, some are treasured by their students, while others are lionized by the public at large. But very few are given the burden of being a celebrity to everyone, everywhere, all the time. Albert Einstein achieved that universality.

The Young Einstein and the Old Einstein
1976In 1911 Einstein, then thirty-two years old, held the post of Professor of Theoretical Physics in the German University at Prague. He had indicated to his friend and former classmate Marcel Grossmann his interest in returning to Zurich to teach at the Polytechnic (The Federal Institute of Technology).

I have talked about Einstein many times before. That I speak once more on the same subject is due to the fact that in the leisure of my old age I have looked through the letters which Einstein wrote to me during his lifetime. There are more than fifty of them, short and long. I copied them all by hand to make doubly sure of their preservation, and this
