The Butterfly That Learned to Live Longer.

Most butterflies live a few weeks. One tropical genus lives nearly a year and barely ages. The reason isn't a single trick but a whole package of traits that evolved together, and it changes how we think about aging itself.

How Crude Oil Learned to Refine Itself

How Crude Oil Learned to Refine Itself

A cheap, unremarkable polymer membrane can refine crude oil with no heat, because the heaviest molecules clog it into a near-perfect filter. How a flaw became the feature, and why it could cut refining energy by a third.

What Jurassic Park Got Wrong About Tyrannosaurus Rex Eyesight

What Jurassic Park Got Wrong About Tyrannosaurus Rex Eyesight

The most famous line in Jurassic Park is biologically backwards. Tyrannosaurus Rex had a stereoscopic visual field wider than a hawk's, visual acuity roughly 13 times sharper than a human's, and depth perception comparable to a military rangefinder. Standing still would not have helped. The science of how we know, drawn from the geometry of the skull itself.

Navigate by field

Six fields. One curiosity.

Cross-cutting principles

Ideas that connect everything.

Feedback

A process in which the output of a system is fed back as input, either amplifying or suppressing the original signal. Feedback loops govern stability and instability across physics, biology, climate, and economics.

Scale

The way systems behave differently depending on their size or resolution. Scaling laws reveal which properties grow proportionally, which change radically, and why the rules that govern one scale often break down at another.

Information

The quantifiable property of a signal or message that can be encoded, transmitted, and decoded. Shannon entropy provides the mathematical foundation. DNA, neural signals, and digital communication are all physical implementations of information processing.

Evolution

The process by which heritable variation, differential reproduction, and natural selection drive cumulative change over time. The principle applies most precisely in biology but appears in analogous forms wherever variation and selection act on replicating systems.

Optimization

The process of finding the best solution within a defined set of constraints. Nature and physics are full of optimisation: Fermat's principle of least time, the principle of least action, natural selection, and algorithmic search are all instances of the same underlying logic.

Uncertainty

The fundamental limits on what can be known or predicted. Heisenberg's uncertainty principle makes this a property of physical reality, not merely of measurement. Statistical mechanics and information theory describe how to reason carefully within those limits.

Applied domains

Where ideas meet the real world.
