A New Theory of Everything That Sets Scalars Equal To Tensors Looks Like Nonsense.

I f your theory of everything has tensors set equal to scalars then it is wrong. Simply put, a scalar is a single number that is widely recognized. A vector consists of 3-4 numbers arranged in a specific sequence, typically representing coordinates and ti ...

Standard Model Stands? New Measurement Of The W Mass At The LHC

Theories in physics come and go, some are popular yet entirely speculative and fade away quickly, like String Theory, and Superdeterminism, while others continue to provide hope for a framework that can unify gravity at the very large and very small levels ...

Some Notes On The Utility Function Of Fundamental Science Experiments

Earlier this year I mentioned here that I would be writing an article on how the utility function of experiments in fundamental science could be specified, as an enabling step toward the formalization of a co-design optimization problem. Now, as the deadli ...

This Year Easter Falls On The Correct Date According To Newton

The most probable date for Good Friday is April 3, 33 AD. This date is due to Isaac Newton. Easter is that holiday that wanders around in the calendar and which you never quite know when will take place. Some get annoyed by that, but frankly I find it cha ...

Flying Drones With Particle Detectors

Nowadays we study the Universe using a number of probes and techniques. Over the course of the past 100 years we moved from barely using optical telescopes, that give us access to the flux of visible photons from galaxies, supernovae, and other objects of ...
