General annotations, reflections, and explorations on science, economics, and ideas that matter.
Discover if good deeds done for selfish motives have moral value. Explore the philosophical debate between consequentialism (results matter) and deontology (intention matters), and why the answer changes your view on charity, volunteering, and altruism.
Discover why glass lets light through while wood blocks it and metal reflects it. The answer involves quantum mechanics, energy gaps, and how electrons interact with photons.
Discover why your clothes, sand, and stones look darker when wet. The answer involves light physics, diffuse vs. specular reflection, and how your brain interprets what you see.
Discover why it seems we find many dinosaur fossils when fossilization is extremely rare. The answer involves 165 million years, perception bias, and the brutal mathematics of extinction.
Discover if wind actually has weight and understand how billions of tons of air above you don't crush you. The answer involves atmospheric pressure, air density, and surprising physics.
Explore why science doesn't try to 'explain everything' -- it answers HOW things work, not WHY they matter. Discover the mathematical (Gödel), physical (Heisenberg) and philosophical limits of science.
Discover why dinosaurs could reach colossal sizes: efficient air sacs, hollow bones, more oxygen in the atmosphere and evolutionary advantages. Understand why modern mammals don't come close.
Deep dive: Discover why science doesn't seek 'absolute truths' -- it tries to prove itself wrong. Understand the scientific method, falsificationism and why 'being wrong and correcting' is science's greatest strength.
Explore the millennial debate between Platonism and formalism: do numbers exist independently of us or are they human creations? And why both sides have convincing arguments.
Understand why fossilization is so rare: it needs rapid death, immediate burial, absence of oxygen and millions of years. Explore amber, ice and the treasures of LagerstÀtten.
Discover why this question starts from a wrong premise: the universe isn't expanding 'into' anything. Space itself is growing, and mathematics works where our intuition fails.
âIs there a center of the universe? The answer from cosmology challenges everything intuition tries to imagine.â
