Some of science's most interesting discoveries happened totally on accident! From insects to infections, and polymers to pacemakers, we've accidentally discovered some pretty cool stuff. Watch this new episode of SciShow, hosted by...

Today's data storage solutions have an expiration date. What's on the horizon to replace them?

SciShow explains how SciShow exists -- and everything else that's ever been made or used on a computer -- by exploring how transistors work together in circuits to make all computing possible. Like all kinds of science, it has its...

From insects to infections, and polymers to pacemakers, scientists have discovered some very cool things entirely by accident, thanks to some careful observation and curiosity.

Imagine a set of electronics as easy to play with as Legos. TED Fellow Ayah Bdeir introduces littleBits, a set of simple, interchangeable blocks that make programming as simple and important a part of creativity as snapping blocks together.

The transistors that power the phone in your pocket are unimaginably small: you can fit more than 3,000 of them across the width of a human hair. But to keep up with innovations in fields like facial recognition and augmented reality, we...

Today, Carrie Anne is going to take a look at how those transistors we talked about last episode can be used to perform complex actions. With the just two states, on and off, the flow of electricity can be used to perform a number of...

Modern computers are revolutionizing our lives, performing tasks unimaginable only decades ago. This was made possible by a long series of innovations, but there's one foundational invention that almost everything else relies upon: the...

Silicon transistors allowed computers to shrink from the size of houses to watches in a short time, but engineers are facing a problem: we've almost hit the limit on how small silicon transistors can get.

In this video Paul Andersen explains how covalent network solids form elementally (like graphite) or by combining multiple nonmetals (like quartz). Covalent network solids contain elements from the carbon group because they have four...

What's the difference between a CPU and GPU? And what the heck is a TPU, DPU, or QPU? Learn the how computers actually compute things in this quick lesson.
