The Scariest Chart In Electrical Engineering
Veritasium
Jul 14, 2026
The Smith Chart acts as a geometric map that compresses infinite impedance values into a finite, usable space. By mapping reflection coefficients instead of raw electrical values, it allows engineers to visualize and solve signal reflection problems through graphical manipulation rather than complex, error-prone calculations.
Key insight: A Smith Chart maps the entire infinite range of possible electrical impedances into a single finite circle, transforming an abstract, scary math problem into an intuitive navigation tool for engineers.
Most satisfying video I've EVER watched
Dorian Develops
Jul 13, 2026
A short, immersive look at the intricate setup of a complex Rube Goldberg machine. The video captures the pure satisfaction of kinetic engineering, where every mechanical action triggers a meticulously planned, seamless response.
Key insight: The machine continues to function through complex environmental transitions, including navigating staircases with mechanical precision.
General relativity from first principles – Adam Brown
Dwarkesh Patel
Jul 10, 2026
Adam Brown deconstructs Einstein's masterpiece, explaining how the curvature of spacetime elegantly unifies gravity with the speed of light. He reveals the core insights behind black holes and why they serve as the most efficient theoretical power plants in the universe.
Key insight: Gravity in General Relativity is not a force in the Newtonian sense, but a consequence of mass curving spacetime—making what we perceive as gravity an 'inertial force' inherent to curved geometry.
Shor's Algorithm for Quantum Computing - Computerphile
Computerphile
Jul 9, 2026
Shor's algorithm leverages the interference of quantum waves to perform efficient integer factorization, a process that threatens modern RSA encryption. By reframing factorization as a period-finding problem, the algorithm exploits wave physics to solve classically intractable equations, offering a reality-based explanation of quantum computing without relying on the 'many-worlds' interpretation.
Key insight: Everything in quantum computing can be reduced to the constructive and destructive interference of waves—it's essentially the same physics that makes JPEGs work, just applied at a quantum state level.
Didn't expect the last one to hold up
Dorian Develops
Jul 8, 2026
Testing how various household items react to extreme stress reveals unexpected physical properties. Common objects like sponges and tape show surprising resistance, while others fail in predictable but fascinating ways.
Key insight: A McDonald's burger bun demonstrates remarkable durability, leading to a humorous comparison with the legendary resilience of a Nokia phone.
Biggest Mysteries in Physics: Antimatter, Dark Energy & ToE - Don Lincoln | Lex Fridman Podcast #497
Lex Fridman
May 29, 2026
Particle physicist Don Lincoln explains that the history of physics is a series of unifications, from Newton's gravity to the Standard Model. He argues that while a 'Theory of Everything' is the ultimate goal, current experimental limits make it a multi-generational challenge, emphasizing that progress relies on empirical validation rather than just theoretical beauty.
Key insight: The magnetic properties of the electron have been measured to twelve significant figures, with theory and experimental data agreeing perfectly for the first ten, a testament to the precision of quantum field theory.
#2506 - Michelle Thaller
The Joe Rogan Experience
May 28, 2026
Astrophysicist Dr. Michelle Thaller joins Joe Rogan to bridge the gap between complex cosmology and the human experience. They explore the profound interconnectedness of the cosmos, the nature of time, and the potential future of human consciousness integrating with AI as we decode the origins of the universe.
Key insight: Everything that makes up your body—the iron, oxygen, and carbon—was forged in the interior of a star; we are literal stardust that evolved to study its own origins.
#2506 - Michelle Thaller
The Joe Rogan Experience
May 28, 2026
A former NASA scientist explores the mysteries of black holes, time dilation, and quantum entanglement. He argues that our universe is far more interconnected than we perceive, suggesting that human consciousness may eventually transcend biological limitations through AI and technological integration.
Key insight: Everything that makes you up, the aluminum, the iron, the oxygen, the carbon, was created in the interior of a star, making astrophysics literally the story of the end of your nose.
#2503 - Eric Weinstein
The Joe Rogan Experience
May 21, 2026
Theoretical physicist Eric Weinstein argues that physics has been stagnant for 50 years due to a high-prestige but failing focus on string theory. He suggests we are in a 'doomsday machine' geopolitical era while potential breakthroughs in post-Einsteinian physics are being hidden within compartmentalized, 'stovepiped' government programs.
Key insight: The world's most prominent theoretical physicist, Edward Witten, is the son of the most prominent anti-gravity researcher of the 1950s, highlighting an often-ignored link between high-prestige physics and fringe research.
World-Renowned Physicist: The Truth About Aliens! UFOs Are Definitely Robotic - Michio Kaku
The Diary Of A CEO with Steven Bartlett
May 21, 2026
Renowned physicist Michio Kaku discusses the future of humanity, from the pursuit of a 'Theory of Everything' to the existential risks posed by AI and quantum computing. He argues that we are currently at a critical turning point in history where science could either usher in an era of unprecedented prosperity or lead to self-destruction.
Key insight: The universe is built on probabilities, and everything we perceive is but a tiny, sliver-like fragment of the total reality existing around us.
Du canon à la Lune : la découverte de la gravité
ScienceEtonnante
Dec 5, 2025
Isaac Newton’s breakthrough was not the apocryphal falling apple, but a thought experiment involving a cannon. By visualizing how a projectile could orbit Earth if fired fast enough, he unified terrestrial ballistics with celestial mechanics, proving that the Moon is essentially a falling cannonball governed by the same inverse-square law of gravity.
Key insight: The Moon stays in orbit because it moves forward at 1 km/s while simultaneously 'falling' toward Earth due to gravity, effectively curving at the same rate as the planet's surface.
What They (Probably) Don't Teach You About Rainbows At School
Veritasium
Dec 1, 2024
Rainbows are not physical objects in the sky; they are unique optical illusions generated by billions of individual droplets. Each drop projects a colored cone of light, and because the phenomenon depends on the precise geometric alignment between the sun, the droplet, and your specific eyes, no two observers ever see the exact same rainbow.
Key insight: The Nobel Prize-winning cloud chamber was invented by C.T.R. Wilson specifically because he wanted to recreate the mysterious 'glories' (colored rings) he observed in mountain mist.
How are holograms possible?
3Blue1Brown
Oct 5, 2024
يكشف هذا الفيديو كيف تخزن الصور المجسمة (الهولوغرام) معلومات بصرية ثلاثية الأبعاد كاملة على وسيط ثنائي الأبعاد. من خلال التلاعب بطور الضوء وتداخله، يمكن إعادة إنشاء حقل الضوء الأصلي بدقة مذهلة، محولاً الفيلم إلى نافذة سحرية ترى من خلالها المشاهد المسجلة كأنها حقيقية.
Key insight: إذا قطعت جزءاً صغيراً من الهولوغرام، فلن تفقد جزءاً من المشهد كما في الصورة الفوتوغرافية؛ بل ستظل قادراً على رؤية كامل المشهد المسجل من خلال تلك القطعة الصغيرة، لأن كل نقطة في الهولوغرام تحتوي على معلومات من المشهد بأكمله.
Answering viewer questions about refraction
3Blue1Brown
Dec 3, 2023
The index of refraction is not merely a measure of how light slows down, but a consequence of phase shifts caused by oscillating charges. This explanation clarifies why light bends, the origins of birefringence, and how phase velocity can exceed the speed of light without violating causality.
Key insight: The phase velocity of a light wave is an emergent property—like the crests of a rotating mechanical wave—and it can exceed the speed of light (c) without carrying information faster than the speed of light.

এই আলোচনাটি প্রিজমের ভেতর দিয়ে যাওয়ার সময় আলোর গতি কমে যাওয়া এবং রঙের বিচ্ছেদের প্রকৃত পদার্থবিজ্ঞান ব্যাখ্যা করে। এটি প্রথাগত 'ট্যাঙ্ক অ্যানালজি' অতিক্রম করে চার্জযুক্ত কণার দোলন এবং ফেজ শিফটের মৌলিক ধারণাটি উন্মোচন করে।
Key insight: প্রিজমের ভেতর আলোর ধীরগতি কেবল একটি কাকতালীয় বিষয় নয়; এটি প্রতিটি চার্জযুক্ত কণার দোলনের ওপর নির্ভর করে, যা প্রিজমের গ্লাসের ভেতরে আলোর কম্পাঙ্কের সাথে অনুরণিত হয়।
