    Momentum: Why the Universe Won't Let You Change Direction

    Why can't you just stop? Stop the bad habit. Leave the dead-end job. End the wrong relationship. You know what you should do. But you don't. Here's why: momentum. The same physics law that makes freight trains take three miles to stop makes your habits impossible to break. The same principle that makes rockets work makes career changes terrifying. In this episode, we're not teaching physics formulas—we're explaining why the universe has a bias, why it wants you to keep doing what you're already doing, and why changing direction is expensive as hell. We'll show you why startups die from lack of momentum, why Amazon redirected momentum instead of restarting, why astronauts drift when they throw tools, and why explosions are perfectly balanced even when they look like chaos. This isn't metaphor. Momentum is conserved—in physics and in life. Once you're moving, staying moving is easy. Starting from rest is brutal. And most people never escape because they don't understand they're fighting a law of physics. Now you do.

    Work and Power: Why Effort Isn't Enough

    You can push against a wall for an hour and do zero work. A child lifting a book does more. Why? Because in physics, work isn't about effort—it's about results. In this episode of Polymath, we break down what work and power actually mean, why the universe doesn't reward trying, and why speed matters as much as strength. Learn why carrying groceries horizontally doesn't count as work, why sprinting up stairs is harder than walking even though the work is the same, why machines are power amplifiers, and how engines, productivity, and even fitness follow the same rules. We'll show you why startups obsess over velocity, why Olympic lifters train differently than bodybuilders, and why distinguishing effort from results changes everything. This isn't just physics—it's a mental model for life. Because the universe's ledger doesn't track how hard you tried. It tracks what you moved and how fast you moved it. Work is the transaction. Power is the speed. And understanding both makes you dangerous.

    Energy Basics: The Currency of Everything

    What is energy, really? In this episode of Polymath, we build a true, intuitive understanding of the most important concept in all of science. Learn what energy actually is (not just "the ability to do work"), explore its many forms—kinetic, potential, thermal, chemical, electrical, radiant, and nuclear—and discover how energy transforms from one type to another in everything from eating breakfast to charging your phone to powering the Sun. We'll trace energy flows through everyday scenarios, explain why nothing is 100% efficient, reveal why energy always "degrades" into heat, and show you how understanding energy changes the way you see the world. Whether you're trying to understand why electric cars have limited range, why athletes eat so much, or why perpetual motion machines are impossible, energy is the answer. This isn't abstract physics—it's the currency that powers every transaction in the universe. And once you understand it, you'll never look at anything the same way.

    Conservation Laws: The Universe's Ironclad Accounting System

    Discover the invisible rules that govern everything in the universe. In this episode of Polymath, we explore conservation laws—the fundamental principles that say energy, momentum, and mass can never be created or destroyed, only transformed. Learn why roller coasters don't need engines after the first hill, why perpetual motion machines are impossible, why explosions follow perfect mathematical rules, and how Einstein revealed that mass and energy are the same thing. We'll show you how these laws explain everything from car crashes to rocket launches, from metabolism to nuclear reactions. More than just physics principles, conservation laws are powerful mental models that reveal a deeper truth: nothing comes for free, trade-offs are real, and the universe keeps perfect books. Whether you're explaining why your phone heats up, understanding how space missions work, or just trying to reason better about cause and effect, conservation laws are your guide to how the world actually works. No heavy math required—just clear explanations, memorable examples, and insights you'll use for life.

    Newton’s Three Laws: The Simple Rules Behind Every Motion in the Universe

    Newton’s Three Laws of Motion are short enough to memorize but powerful enough to explain nearly everything that moves — cars, rockets, sports, falling objects, walking, flying, and even planetary orbits. In this episode, we bring the laws to life with clear explanations, real‑world examples, and fun stories from Newton’s plague‑year breakthroughs. You’ll learn why seatbelts exist, why rockets work in space, why heavier objects don’t fall faster, and how all three laws combine to create the motion you see every day. This is classical physics made vivid, practical, and conversation‑ready — a must‑know toolkit for any modern polymath.

    Physics: The Hidden Rulebook of Reality

    Physics isn’t just equations — it’s the operating system of the universe. This episode introduces physics as the deepest rulebook behind everything: smartphones, rockets, bridges, fire, time, and even economics. We explore matter, energy, motion, space, and time with vivid examples and zero heavy math. You’ll learn why everything you touch is mostly empty space, why time isn’t universal, why microwaves heat food, and why GPS needs Einstein to work. From quantum weirdness to the expanding universe, this episode makes physics feel intuitive, exciting, and essential — the perfect foundation for future science deep dives.

    Exchange Rates: Why Money Has Different Prices Around the World

    Why is one U.S. dollar worth many pesos but less than one British pound? Why do exchange rates constantly change? And why does the U.S. dollar dominate global finance? This episode demystifies currency exchange using intuitive examples — from baseball cards to vacation money to online shopping. You’ll learn how trust, inflation, investment flows, and global trade shape currency values, why central banks intervene, and how exchange rates quietly affect your daily life. With mind‑bending facts about time dilation in GPS, countries that replaced their currencies, and the physics‑like rules of global money, this episode makes you financially and globally literate.

    Trade Deficits: Why Countries Buy More Than They Sell

    Trade deficits are one of the most misunderstood ideas in economics. Are they bad? Are they normal? Do they mean a country is “losing”? In this episode, we break down trade deficits using simple analogies, real historical stories, and modern global dynamics. You’ll learn why countries like the U.S. run deficits for decades, why strong currencies and high consumer demand matter, and when deficits signal strength versus weakness. Packed with surprising facts — from ancient Rome’s silk obsession to China’s export boom — this episode gives you the clarity to decode global trade like a pro.
