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

The Königsberg Bridge Problem: can you cross all 7 bridges exactly once? Euler proved it impossible, creating graph theory in the process. Math solving practical puzzles!

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.

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

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!

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.
