How to derive general relativity from Wolfram Physics

Here's a masterclass from Jonathan Gorard. One of the most compelling results to come out of the Wolfram Physics is Jonathan's derivation of the Einstein equations from the hypergraph. Here's how general relativity falls out of the Wolfram model.

How to derive quantum mechanics from Wolfram Physics

Jonathan Gorard explains how quantum mechanics can be derived from the Wolfram model. Here, at last, is how the observer causes the collapse of the wavefunction, reducing Schrödinger's half live, half dead cat to one that's either dead or alive.

Peer review is suffocating science

Peer review does precisely the opposite of what you think it does. It prevents the good papers from being published, and ensures that only the bad ones get through. If we want to reverse the stagnation of science over the last 50 years, then we've got to get rid of peer review.

Is the universe a tautology?

One rule to rule them all?

Why has there been no progress in physics since 1973?

The twentieth century was a truly exciting time in physics. From 1905 to 1973, we made extraordinary progress probing the mysteries of the universe. Then, in 1973, this extraordinary progress... stopped. Why?

How to find causally invariant rules

How to draw the hypergraph in Wolfram Physics

Is Wolfram Physics the next scientific revolution?

For the last few hundred years, all our theories of physics have been mathematical. If Stephen Wolfram is right, from now on, our most fundamental theories of physics may be computational. This shift feels to me like a scientific revolution.

Hypergraphs are everywhere

Wolfram Physics models the universe as a hypergraph. Maybe I'm just seeing things, but it seems to me that hypergraphs are everywhere: physics, chemistry, biology, neurology, ecology, sociology, technology. What I want to know is: Why? Why are hypergraphs everywhere?

Where to apply Wolfram's rules?

The question of where to apply Wolfram's rules is not as easily answered as you might think. This seemingly straightforward question will take us into the philosophy of time, causality, consciousness, contingency and determinism. And it'll lead us towards some of the most important concepts in Wolfram Physics: the multiway graph, branchial space and causal invariance.

Beware invisible things

As I explore Wolfram Physics, I'm aware of certain invisible things that we believe in now, but we're going to have to let go, if Stephen Wolfram is right. And I'm also aware of the temptation to replace this old set of invisible things with a new set of invisible things. Here's why we'd do well to resist.

How to measure the dimensionality of the universe
