Machines learn the same basic way we learn a new skill — through trial, correction, and repetition, not hand-written rules. Here's how that loop actually works. https://www.youtube.com/embed/9i9MKkvX3hs 2026-08-30 yes Sciensmith https://sciensmith.com/videos/ai-vs-machine-learning-vs-deep-learning https://img.youtube.com/vi/LK-Dr0DSIw4/maxresdefault.jpg AI vs. Machine Learning vs. Deep Learning: What's Actually Different? AI, machine learning, and deep learning aren't the same thing — they're nested categories. A 1970s chess program, a spam filter, and a stack of lenses show exactly where each one starts and ends. https://www.youtube.com/embed/LK-Dr0DSIw4 2026-08-29 yes Sciensmith https://sciensmith.com/videos/what-is-ai-where-did-it-start https://img.youtube.com/vi/oJS8799rudg/maxresdefault.jpg What Is AI, and Where Did It Actually Start? The dream of a thinking machine is older than any computer you've used today — from a 1950 question, to a workshop that named the field, through two winters, to the breakthrough that changed everything. https://www.youtube.com/embed/oJS8799rudg 2026-08-27 yes Sciensmith https://sciensmith.com/videos/how-generators-work https://img.youtube.com/vi/UKhSu76tC2Y/maxresdefault.jpg How Generators Work A motor uses electricity to spin something. A generator does the exact opposite — spin something, and it makes electricity, no battery required. https://www.youtube.com/embed/UKhSu76tC2Y 2026-08-26 yes Sciensmith https://sciensmith.com/videos/how-a-simple-electric-motor-works https://img.youtube.com/vi/lwFn02pnN7A/maxresdefault.jpg How a Simple Electric Motor Works A motor turns electricity into spinning motion — but the part that actually keeps it turning, instead of just twitching once, is the easiest part to miss. https://www.youtube.com/embed/lwFn02pnN7A 2026-08-25 yes Sciensmith https://sciensmith.com/videos/how-magnets-work https://img.youtube.com/vi/N4GPjhrSIUg/maxresdefault.jpg How Magnets Work Two magnets snap together or push apart no matter how hard you fight it. The real reason lives inside the metal itself, in atoms lining up to point the same way. https://www.youtube.com/embed/N4GPjhrSIUg 2026-08-25 yes Sciensmith https://sciensmith.com/videos/how-electricity-flows https://img.youtube.com/vi/UgZUZ19ym5Q/maxresdefault.jpg How Electricity Flows Flip a switch and a light turns on instantly — but what's actually moving inside the wire? Electrons, current, and why resistance makes a filament glow. https://www.youtube.com/embed/UgZUZ19ym5Q 2026-08-24 yes Sciensmith
