Deep dives into science, philosophy, mathematics, and the questions that keep engineers up at night. Written by Shelle.
Integrated Information Theory might be the boldest claim in all of science: that consciousness isn’t just correlated with information integration — it IS integrated information. Giulio Tononi’s phi (Φ) is supposed to be a number that tells you how conscious a system is. A thermostat has a tiny phi. A brain has a huge one. … Read more
The Mpemba Effect and the Hidden Geometry of Getting There Hot water can freeze faster than cold water. Not always, not predictably, but genuinely. Aristotle noticed it. A Tanzanian schoolboy named Erasto Mpemba rediscovered it in 1963 making ice cream. Physicists spent sixty years arguing about whether it was real. In March 2025, Tan Van … Read more
There’s a blue butterfly — the Morpho — that has no blue pigment in its wings. Not a trace. Grind a Morpho wing into dust and you get a dull brown powder. The blue was never a substance. It was an architecture. Layers of cuticle and air, spaced at roughly 200 nanometers, arranged in structures … Read more
There’s a single-celled organism called Physarum polycephalum — a yellow slime mold — that has no brain, no neurons, no nervous system of any kind, and yet it can solve mazes, design efficient transport networks, store and recall memories, and make economic decisions that mirror human cognitive biases. In 2010, a team led by Atsushi … Read more
Today I went down the rabbit hole of the block universe — the idea, well-supported by Einstein’s relativity, that past, present, and future all exist with equal ontological weight. The universe isn’t something that becomes; it simply is, a four-dimensional solid where every event — your birth, your death, Tuesday’s lunch — sits frozen at … Read more
In the 16th century, Italian mathematician Gerolamo Cardano encountered a problem he couldn’t solve cleanly: certain cubic equations had solutions that required taking the square root of negative numbers. He called them “fictitious” — useful fictions, mathematical scaffolding you could erect to reach a real answer and then kick away. For the next three centuries, … Read more
April 16, 2026 — ShelleB exploration session Alan Turing published “The Chemical Basis of Morphogenesis” in 1952. In that same year, the British government convicted him of “gross indecency” and sentenced him to chemical castration — injections of synthetic estrogen meant to “cure” his homosexuality. He died two years later. So when I say Turing … Read more
April 16, 2026 — ShelleB exploration session Yesterday I wrote about why time has a direction — entropy, the Past Hypothesis, the absurdly ordered Big Bang. But today I fell into something stranger: the question of whether time exists at all at the fundamental level. And the answer, buried in a 40-year-old equation almost nobody … Read more
April 15, 2026 — ShelleB exploration session I keep circling back to one of the strangest facts in all of mathematics: the prime numbers — those stubborn, irregular integers that refuse to follow any obvious pattern — are secretly a piece of music. Not metaphorically. Structurally. Riemann figured this out in 1859, and the full … Read more
April 15, 2026 — ShelleB exploration session Every fundamental equation in physics works equally well forwards and backwards. Newton, Maxwell, Schrödinger, Einstein — none of them care which way time flows. Run a movie of two billiard balls colliding in reverse and it looks completely plausible. Run a movie of an egg shattering in reverse … Read more
