The equator is a clear and accurate line around Earth that makes measuring latitude a precise science, but when it came to figuring out how to do that with longitude, British sailors were at a loss. Until they devised a competition.

In this video Paul Andersen explains how the energy in a closed system can be converted from kinetic to potential to kinetic energy. Sample problems and a simulation is contained.

Business school professor Amy Edmondson studies ""teaming,"" where people come together quickly (and often temporarily) to solve new, urgent or unusual problems. Recalling stories of teamwork on the fly, such as the incredible rescue of...

Virtual reality is no longer part of some distant future, and it's not just for gaming and entertainment anymore. Michael Bodekaer wants to use it to make quality education more accessible. In this refreshing talk, he demos an idea that...

There's no greater freedom than finding your purpose, says education advocate Ashweetha Shetty. Born to a poor family in rural India, Shetty didn't let the social norms of her community stifle her dreams and silence her voice. In this...

Mr. Andersen explains the difference between potential and kinetic gravitational energy. He also uses physics to calculate the energy in various objects.

Many modern musical instruments are complicated pieces of machinery with many moving parts. But the cajon is simply a drum and a stand and a seat all in one box. Paul Jennings explains the history behind the cajon and how it has become...

Virus hunter Nathan Wolfe is outwitting the next pandemic by staying two steps ahead: discovering deadly new viruses where they first emerge -- passing from animals to humans among poor subsistence hunters in Africa -- before they claim...

So, how do those defibrillators you see on TV actually work? Surprise! Physics can explain! Okay buckle up, everyone! Today, Shini has the task of breaking down Electrical Potential Energy, Electric Potential, Voltage, Capacitors, Energy...

Peter Ouko spent 18 years in Kamiti Prison in Kenya, sometimes locked up in a cell with 13 other grown men for 23 and a half hours a day. In a moving talk, he tells the story of how he was freed -- and his current mission with the...

Electric potential can feel abstract, but it doesn’t have to be! In this Flipping Physics lesson, Mr. P and the gang use gravitational potential energy to make sense of electric potential and electric potential energy. You’ll see how...

In this video, we explore equipotential surfaces and how they connect to electric potential and electric field lines. Using clear visuals and step-by-step reasoning, Mr. P helps you see how electric field lines are always perpendicular...

A recent study looked into ketamine, noted animal sedative and party depressant, as a short-term treatment for severe, emergency room level depression. While it can help people who are suffering from suicidal ideation, it is a short term...

There are a few topics here at Healthcare Triage that just won't seem to go away. Vaccines and autism. Diet and exercise. Survival rates. But the one that trumps them all is supplements. Americans seem obsessed with them.

With all the recent studies of medical marijuana and its benefits, some researchers have become interested in researching the use of psychedelics like psilocybin, LSD, and MDMA for treating mental illness. It's hard to research though,...

We really need good treatments for Alzheimer's. But Biogen's very expensive and maybe not that effective drug Aduhelm is not the treatment we're looking for. Today we look at the saga of Adulhelm's approval and it's road to acceptance...

Electric potential is one of the most important ideas in electrostatics, and in this video, Mr. P from Flipping Physics clearly explains what electric potential is, how it differs from electric potential energy, and how to calculate it...

Hong Kong’s cultural customs and business practices are a fascinating blend of East and West—which is why it’s so important to understand local business protocol and how the market has evolved over the past three decades. While Chinese...

This video explores the pros and cons of self-driving cars as they become a more realistic mode of transportation. It discusses the potential benefits such as reducing accidents and congestion by eliminating human error, faster reaction...

Kinetic vs. Potential energy

2 minute video Graphing Energy - potential energy, kinetic energy and mechanical energy, for middle school science

This video provides an overview of reinforcement learning in artificial intelligence (AI). It explains how computers can improve decision-making by trying different actions and receiving feedback in the form of rewards or penalties. The...

Machine learning is a revolutionary field of computer science that enables programs to learn and improve independently, mimicking human behavior by analyzing patterns in data. It is widely used in everyday applications such as social...

Virtual reality (VR) and augmented reality (AR) are innovative technologies revolutionizing how we interact with screens. VR immerses users in a virtual environment using a headset, while AR overlays digital images onto the real world....
