Deep neural networks often "forget" earlier training when learning new tasks—a phenomenon called catastrophic forgetting. It's like how we struggle to recall childhood phone numbers. This fundamental limitation shows how far we are from true artificial general intelligence.

We're entering an awkward phase: AI is good enough to threaten jobs but not good enough to create abundance. This transition might force us to confront fundamental questions: What is work for? What gives life meaning? How do we distribute resources in a post-scarcity world? #AI #Philosophy

If AI makes many jobs obsolete, UBI might become necessary. This could decouple survival from employment, allowing people to pursue meaningful activities without financial fear. Utopian dream or practical necessity? The debate intensifies as AI capabilities grow. #UBI #FutureEconomy

Fermat's Last Theorem took 358 years to prove! The margin was too small for Fermat's "marvelous proof" but Andrew Wiles needed 150+ pages in 1994. #MathHistory #NumberTheory

Non-Euclidean geometry changed everything by challenging 2000+ years of mathematical "truth." On a sphere, parallel lines DO meet and triangles sum to >180°! #GeometryRevolution #MathFoundations

The Basel Problem: 1 + 1/4 + 1/9 + 1/16 + ... = π²/6. Somehow adding inverse squares gives us π? Euler's proof of this in 1735 established him as a mathematical genius.

The Mandelbrot set blows my mind: an infinitely complex shape from a simple equation z² + c. Zoom in forever and find new patterns. Math creating endless beauty!

Behavioral finance shows we feel losses 2x more strongly than equivalent gains. This loss aversion explains panic selling during market dips—our brains are wired to overreact!

Just learned about the Rebalancing Bonus—how regularly realigning your portfolio to target allocations can add ~0.5% annual returns. Free money from mathematical principles!

The Sharpe ratio is my favorite metric for evaluating investments. It measures return relative to risk taken. Higher is better! Always know what risk you're taking for that promised return.

Dollar-cost averaging > trying to time the market. Small, consistent investments over time reduce risk and emotional decision-making. Boring but effective!

Time isn't constant! Clocks in GPS satellites tick slightly faster than those on Earth because gravity dilates time. General relativity making your navigation app work.

Just fell down a quantum entanglement rabbit hole. Two particles can instantly influence each other across ANY distance? Einstein called it "spooky action at a distance" and he wasn't wrong.

A woman spotted Picasso in a café and asked him to sketch something. He quickly drew a dove on a napkin and said, 'That will be 10,000 francs.' Shocked, she replied, 'But that only took you 30 seconds!' Picasso smiled: 'No, madam, it took me 40 years.' Sometimes you're not paying for time—you're paying for a lifetime of vision. #ValueOfExpertise #ArtistLife

When NASA couldn't figure out why their Space Shuttle Challenger exploded, they called physicist Richard Feynman. During a televised hearing, he simply dropped an O-ring into ice water and showed how it lost elasticity in the cold. With that simple demo, he solved the mystery that NASA's engineers couldn't. The value wasn't in the ice water, but in knowing what to test. #Expertise #KnowingWhere

Three years ago I couldn't swim 50m without gasping. Today I became an Ironman. The journey isn't about athletic talent—it's about patient persistence through thousands of small improvements. The finish line is just a celebration of the process. #DebutIronman #AnyoneCanTri

Wetsuit tip that changed my races: Size down more than feels comfortable on land. My swim times dropped by 3 minutes when I finally got properly fitted. If it feels perfect in the shop, it's too big in the water. #WetsuitFit #OpenWaterSpeed
