Real numbers and reality

We’ve all learnt that the complex numbers play a fundamental role in quantum physics, while – in classical physics – they are just a matter of mere convenience. Many people have commented on this fact, and – for no particular reason other than possibly his dramatic tone – we quote Dyson, who says: “…But then came the surprise. Schrödinger put the square root of minus one into the equation, and suddenly it made sense. Suddenly it became a wave equation instead of a heat conduction equation. . . .

The B-M-V Effect

I’d like to tell you about testing quantum gravity in the lab. It is possible to do so and this is surprising because gravity is by far the weakest of all the forces (I might devote another blog to arguments why gravity can never be tested to be quantum!)

On the importance of interpretations

It’s well-known that any physicist ought to be aware of as many possible explanations or interpretations of one and the same phenomenon. Of course, the more perspectives we have the better we understand something, but – in physics – there is more to this.

Everything is Just (a Perturbed) Nothing

I’ve been advocating the view of the universe in which everything is made up of different kinds of quantum waves. Each particle is simply a vibration of one kind of a quantum wave or another. I myself am a vibration of the Vedral field, which is not a fundamental field 😊, but instead consists of the electromagnetic, quark, gluon fields and so on.

The Current State of Quantum Technologies

I’ve been asked by a reader to write about the current state of quantum technologies. There has been a real buzz about it outside of the physics (academic) community for a while now and all the major companies are investing large amounts of money into it…

The Infamous Mod Square

Because everything in quantum physics behaves like a wave, the primary entities are given by what are known as amplitudes. Amplitudes can be thought of as propensities (to borrow a term from Aristotle) for a wave of one configuration to – later on – acquire another configuration.
