Roger Penrose won the 2020 Nobel Prize for proving black holes must exist. He also drew the impossible triangle that inspired Escher and argues quantum effects in microtubules produce consciousness.

Erwin Schrödinger's life, wave mechanics, and documented biography: the quantum pioneer who fled Nazi Austria, kept a private 'love notebook', and thought up the most famous cat in science.

Archimedes of Syracuse: buoyancy, levers, war machines, and verified quirks — the Eureka story examined, the circle and the soldier, and why he came closer to calculus than anyone for 1,800 years.

Galileo Galilei's life, discoveries, and verified quirks: his preserved finger on display, three illegitimate children, the Inquisition recantation, and the apocryphal 'Eppur si muove'.

Carbon-14 dating lets scientists calculate the age of once-living organisms with remarkable accuracy. Here is the physics behind how a radioactive isotope became archaeology's most powerful clock.

Isaac Newton's biography, laws of motion, optics, and verified quirks: needle behind the eyeball, alchemy obsessions, plagiarism wars, and a life of deliberate solitude.

J. Robert Oppenheimer's life, quirks, and legacy: the Cambridge poisoning attempt, Bhagavad Gita at Trinity, and the security clearance that ended his career.

Mirrors don't actually flip left and right — they flip front to back. The physics of reflection, from bronze polish to the 39-meter ELT telescope.

Gravity explained: Newton's universal law, Einstein's curved spacetime, gravitational waves, and why GPS satellites must correct for it.

How electricity works: voltage, current, resistance, AC vs DC, power generation, the grid, and why birds don't get electrocuted.

Why is the sky blue? Learn how air scatters sunlight, why sunsets turn red, and how dust and human color vision change the colors we see overhead.

Liu Cixin's chilling answer to the Fermi paradox: the universe is a silent hunt, and broadcasting your location is suicide. Here's the theory.
