Learn how advances in technology allow boats to go faster than ever before in this video from NOVA: “Making Stuff Faster.” Host and technology columnist David Pogue examines two factors that limit speed—energy and resistance—and describes how Oracle Team USA maximizes the speed of its boat. Instead
Learn about in advances in powered exoskeletons—a kind of wearable robot—in this video adapted from NOVA scienceNOW. Correspondent and New York Times technology columnist David Pogue explores the development of sophisticated robots that can be integrated with the human body. The company Ekso Bionics
Learn how one company took inspiration from nature to reinvent the robotic arm in this video excerpted from NOVA: “Making Stuff Wilder.” Host and technology columnist David Pogue meets with engineer Heinrich Frontzek to find out about the Bionic Handling Assistant—a machine modeled after an elephant
Are you hoping to increase your intelligence? Maybe you need a few tips, or perhaps you’re curious as to what common traits intelligent people seem to have. Well, you clicked the right video, my friend. Writer: Michal Mitchell Script Editor & Manager: Kelly Soong VO: Mithrilda Animator: Zuzia IG
There’s a strong difference between being lonely and being alone. When we experience long days at work, go to one big social event after another, or go to school, our bodies will want to enter hermit mode. And that’s normal. Just like batteries, we need time to recharge, and what better way than to
What is risk? And what is risk assessment? [Note from AM - I've been surprised at how tough it is to talk about risk in an accessible yet accurate way in just a couple of minutes. Looking back over this video and next week's, I can feel the paranoia creeping in that some of the basic concepts are
Sometimes, we all need a pick me up. To be vulnerable means to put ourselves in a position that could potentially hurt us.

The law of mass action is applied to the autoprotolysis of water. Through further considerations, a constant Kw can be defined. This is called the ionic product of water. This is the basis of the pH value. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done
With the help of the standard hydrogen half-cell, the potentials of all other half-cells can be determined. The standard hydrogen half-cell represents the defined 0-point. Therefore, these measured potentials are referred to as standard potentials. Original: "Wolfgang Dukorn" Original: German. All
