Dark cover with the title in serif type — the word Derivative in italic pink — above the subtitle: desire is the rate of change of identity; a ghosted d/dt glyph fades into the lower right corner.

“I Want” Is the Derivative of “I Am”

If “I Am” is a position and “I want” is a velocity, then desire is the derivative of identity: every want splits into a component that grows you and a component that turns you, a want is felt only when something resists it, and whether knowing can bend wanting turns out to be the oldest fight in moral psychology. … Continue reading“I Want” Is the Derivative of “I Am”

Dark cover with the title Collapse Is Not a Rotation, the word Rotation in italic pink, and a large ghosted P-psi glyph in the lower right.

Collapse Is Not a Rotation

Quantum mechanics contains exactly two ways a state can change: a rotation that is reversible, deterministic and always running, and a projection that keeps one component and deletes the rest. A lesson for philosophers and theologians on what the geometry fixes about wave function collapse — its shape, its weights, its basis, even the impossibility of dating it — and the one question it leaves open. … Continue readingCollapse Is Not a Rotation

Dark cover with the title The Parts Do Not Determine the Whole, the word Determine in pink italic, over a faint tensor-product symbol: a circle with a diagonal cross through it.

The Parts Do Not Determine the Whole

Join two quantum systems and their state spaces multiply rather than add, and almost nothing in the product comes apart again into a state for each half. A lesson on entanglement for philosophers and theologians: what Bell actually ruled out, why entangled is not the same as non-local, and why the honest claim is a failure of supervenience rather than a disappearance of the parts. … Continue readingThe Parts Do Not Determine the Whole

Dark title card reading 'The i Is in the Equation' above two boxed equations: F equals m a in amber with a green tick marked 'Re Psi solves it', and the Schrodinger equation in pink with a cross marked 'Re psi does not'.

The i Is in the Equation

Classical physics uses complex numbers constantly and can always discard them at the end. Quantum physics cannot, and the reason is exact: take the real part of a classical solution and you still have a solution — take the real part of a wavefunction and you have nothing. A lesson for philosophers and theologians on what F = ma actually claims, and what quantum mechanics does and does not license. … Continue readingThe i Is in the Equation
