Paul Andersen explains the importance of argumentation in improving both understanding and design. This video begins with a discussion of the heliocentric and geocentric model of the Universe that eventually lead to the Copernican...

Today Shini explains the law of conservation, beginning with simple, steady-state systems. We’ll discuss conversion and yield, accumulation, and how generation and consumption can affect how much accumulation there is in a system.

In 1978, Diane Hartley was writing her undergraduate architecture thesis when she made a shocking discovery. After weeks of poring over the Citicorp Center's building plans, she'd stumbled on an oversight that threatened to topple the...

Geneticist Jennifer Doudna co-invented a groundbreaking new technology for editing genes, called CRISPR-Cas9. The tool allows scientists to make precise edits to DNA strands, which could lead to treatments for genetic diseases ... but...

This video is about compressed air cans (aka gas dusters) and why they get cold when you spray them. They cool off because the refrigerant inside (1,1-difluoroethane) is under pressure and boils off when the pressure lowers, and energy...

Without water, a human can only survive for about 100 hours. But there's a creature so resilient that it can go without it for decades. This 1-millimeter animal can survive both the hottest and coldest environments on earth, and can even...

The band OK Go dreamed up the idea of a massive Rube Goldberg machine for their next music video -- and Adam Sadowsky's team was charged with building it. He tells the story of the effort and engineering behind their labyrinthine...

Now that we've talked about failure points, let's talk about how to fix them. In this episode of Crash Course Kids, Sabrina shows us how to set up models and trails to find and fix failure points.

Melissa Marshall brings a message to all scientists (from non-scientists): We're fascinated by what you're doing. So tell us about it -- in a way we can understand. In just 4 minutes, she shares powerful tips on presenting complex...

We all know that failure is bad... but is it? Actually, Engineers need things to fail so they can understand how to make things better. In this episode of Crash Course Kids, Sabrina chats to us about failure points and how they can help...

We've been promised a future of chrome -- but what if the future is fleshy? asks biological designer Christina Agapakis. In this awe-inspiring talk, Agapakis details her work in synthetic biology -- a multidisciplinary area of research...

Paved roads are nice to look at, but they're easily damaged and costly to repair. Erik Schlangen demos a new type of porous asphalt made of simple materials with an astonishing feature: When cracked, it can be "healed" by induction heating.

GPS location apps on a smartphone can be very handy when mapping a travel route or finding nearby events. But how does your smartphone know where you are? Wilton L. Virgo explains how the answer lies 12,000 miles over your head, in an...

Physiatrist and engineer Todd Kuiken is building a prosthetic arm that connects with the human nervous system -- improving motion, control and even feeling. Onstage, patient Amanda Kitts helps demonstrate this next-gen robotic arm.

Eighty-five percent of the matter in our universe is dark matter. We don't know what dark matter is made of, and we've yet to directly observe it, but scientists theorize that we may actually be able to create it in the Large Hadron...

How do we design the most efficient machines and processes? Today we’ll try to figure that out as we discuss heat & work, reversibility & irreversibility, and how to use efficiency to measure a system.

La Luna puede estar a 1.3 segundos luz de distancia, ¿pero por qué medimos distancias usando tiempo? ¡Muchas gracias a las siguientes personas que nos apoyan en Patreon! Ayudáis a que MinutoDeFísica sea posible. Marcelo Enrique Anguita...

The World Wide Web is used every day by millions of people for everything from checking the weather to sharing cat videos. But what is it exactly? Twila Camp describes this interconnected information system as a virtual city that...

A footnote to the video about Neutrino Shape-Shifting: https://youtu.be/7fgKBJDMO54 Sixty Symbols Video on Double Pendulum: https://www.youtube.com/watch?v=izy4a5erom8 Physics of The Double Pendulum:...

Thanks to the Heising Simons Foundation (https://www.hsfoundation.org/) for their support of this video, and of short range gravity research. This video is about how little we know about the behavior of gravity at short length and...

Taylor Wilson was 14 when he built a nuclear fusion reactor in his parents' garage. Now 19, he returns to the TED stage to present a new take on an old topic: fission. Wilson, who has won backing to create a company to realize his...

The previous videos in this series: Chapter 1: Why Relativity is Hard Chapter 2: Spacetime Diagrams This video is chapter 3 in my series on special relativity, and it covers boosts, galilean transformations, newtonian relativity, and of...

We tend to think of blindness as something you're born with, but with certain genetic diseases, it can actually develop when you're a kid, or even when you're an adult. But could blind eyes possibly regenerate? David Davila explains how...
