Watch as a team from MIT demonstrates how to use a catalyst to split water into molecular hydrogen gas and oxygen gas. This process is used in the Science Buddies Project Idea: Water to Fuel to Water: The Fuel Cycle of the Future https://www.sciencebuddies.org/science-fair-projects/project-ideas/Chem_p099/chemistry/fuel-cell?ytid=nrJhJ-ReqJ8&ytsrc=description
MIT researchers: Dr. Elizabeth R. Young, Yogesh Surendranath, and Thomas Teets.
This is the second video in a two-part series about squishy circuits for classroom use. This video goes into more detail about the basic circuit concepts that can be taught using squishy circuits. Kit available here: https://www.homesciencetools.com/product/squishy-circuits-kit/?aff=SB1

The main ideas behind PCA are actually super simple and that means it's easy to interpret a PCA plot: Samples that are correlated will cluster together apart from samples that are not correlated with them. In this video, I walk through the ideas so that you will have an intuitive sense of how PCA plots are draw. If you'd like more details, check out my full length PCA video here: https://youtu.be/_UVHneBUBW0

Today we’re going to teach John Green Bot how to tell the difference between donuts and bagels using supervised learning! Supervised learning is the process of learning WITH training labels, and is the most widely used kind of learning with it comes to AI - helping with stuff like tagging photos on Facebook and filtering spam from your email. We’re going to start small today and show how just a single neuron (or perceptron) is constructed, and explain the differences between precision and…

How small is a TRANSISTOR exactly? Companies like Intel and AMD talk about transistors being 2 or 3 nanometers large, but is that actually how small they are? In this video, we're going to zoom in on the smallest devices and technologies that drive our modern world.
If you're wondering why some devices are out of order in regards to size, here's the reason. The order of devices shown is primarily organized by decreasing size, however sometimes we prioritize the year in which the technology…
