Energy expert Sebastián Kind helped Argentina go from virtually no renewable energy to generating nearly 40 percent of its electricity from wind and solar in just six years, despite economic crises and skepticism. How did the country's...

For AI to achieve its full potential, non-experts need to contribute to its development, says Rumman Chowdhury, CEO and cofounder of Humane Intelligence. She shares how the right-to-repair movement of consumer electronics provides a...

Hundreds of millions of migrant workers travel within their countries to seek out means of survival — often leaving behind all they know for months or even years. Many face poverty and exploitation, and they need a robust social safety...

Unfortunately, the universe isn't made of sugarcoated fried dough. However, here are a few ways donuts are still managing to find their way into the physical world.

In 2003, Singapore's national water agency launched an unprecedented program to provide more than 50% of their nation's water supply by recycling wastewater. The program had been planned for decades to ensure the island nation never ran...

Microphones keep getting smaller and smaller, but have you ever asked what it would be like to have a bigger one in the form of a shirt? And though we tend to incorrectly think that we’re having two-way conversations with our pets, we...

Jessi and Augusto from Animal Wonders talk with Hank about how they got their really cool jobs. Plus they introduce Hank to a Mali uromastyx!

The Apollo program was famous for being risky and expensive. It sent multiple daring astronauts to the moon, but had a crunched timeline, and lacked modern tech. In this special episode of SciShow, we'll be discussing... was the Apollo...

Devastating vulnerabilities are hiding in the technology in programs, protocols, and hardware all around us. Most of the time, you can find ways to protect yourself.

It's taken the work of many programmers to turn computers into something we carry in our pockets, and here are five (technically 10!) that we think you should be aware of.

In our last list of strange aircraft, we stuck to covering the weirdest jets to take to the sky, but there are plenty of other types of bizarre flying machines out there! In this episode, Hank will tell you about five other unlikely...

Despite common belief, retirement takes more than financial planning. And while you may be beyond ready to go on permanent vacation, you also have to psychologically prepare for when the novelty wears off. Riley Moynes explains the four...

Today, we are going to start our discussion on user experience. We've talked a lot in this series about how computers move data around within the computer, but not so much about our role in the process. So today, we're going to look at...

Why are we so deadlocked on climate, and what would it take to overcome the seemingly insurmountable barriers to progress? Policy entrepreneur TED Halstead proposes a transformative solution based on the conservative principles of free...

The Apollo 11 moon landing was about the astronauts, mission control, software and hardware all working together as a seamless integrated system. None of which would have been possible without the contributions of one engineer: Margaret...

Today, we're FINALLY going to talk about PC Gaming. So the personal computer is the precursor to the console, but it's not quite accurate to say that it just led to the console. PCs and the video games created on them have and continue...

Today we create a game and then build an AI to destroy it. Our game is called TrashBlaster, and it’s like Asteroids but with trash in the ocean, and instead of a spaceship John Green Bot is wielding a laser. We'll use machine learning...

The universe is made up of information, similar to a computer, and physics (you know, the basis of the universe) certainly is based on computational principles. But is it running some grand program? Will the answer be 42? Make sure you...

As we mentioned last episode, one of the best test spaces for building new AI systems are games. This is because games provide a great framework for an AI to learn an objective and slowly improve. In recent years, AI has made huge...

Stephen Wolfram, creator of Mathematica, talks about his quest to make all knowledge computational -- able to be searched, processed and manipulated. His new search engine, Wolfram Alpha, has no lesser goal than to model and explain the...

To freshen up your Apollo knowledge, here is a good dive into the science and engineering that put people on the moon.

John Green Bot wrote his first novel! Today, in our first ever Lab we’re going to program a neural network to recognize handwritten letters to convert the first part of John Green Bot’s novel into typed text. To do this we’re going to...

Mohamad Jebara loves mathematics -- but he's concerned that too many students grow up thinking that this beautiful, rewarding subject is difficult and boring. His company is experimenting with a bold idea: paying students for completing...

The next step toward a holodeck might be the ability to actually touch a simulation, and we’re getting closer—using sound.
