How Horses Save Humans From Snakebites Teacherflix 20 Views • 7 months ago

This video is sponsored by Brilliant. The first 200 people to sign up via https://brilliant.org/veritasium get 20% off a yearly subscription. To make antivenom, you first need to collect venom from the world’s most deadly snakes.

Huge thanks to the Australian Reptile Park for having us over to film – special thanks to Zac Bower for milking all of these snakes for us and Caitlin Vine for organizing the shoot. Absolute legends. https://www.reptilepark.com.au

Huge thanks to Dr Timothy Jackson from the Australian Venom Research Unit for answering our questions, and fact checking the script. This video would not have been the same without you.

Thanks to Seqirus Australia for providing B-roll footage of the horses and the antivenom production.

Improved math is a channel created to provide additional instruction on essential math concepts. I’m passionate about math and I know first-hand how important math concepts are in the real world.

Teachers, parents, guardians, homeschoolers, and students can use these videos to help reinforce math skills. These math videos are designed to help teach yourself math or provide self-study math tools to assist when additional instruction is needed. Teaching math and learning math has changed the way many students learn in this virtual environment and during the pandemic. Having on-demand math videos can provide math tutoring needed when children are not able to get help from their teachers after school hours or when trying to do math at home.

The library of math tutorials that I create can also be used as supplemental instructional material for homeschool math. Each full-length video comes with a subsequent knowledge check or math practice problems which serve as a virtual math topic worksheet to test your understanding of each skill. These videos can be paused to work out the problems on your own, then unpaused to check your answers. All of these videos can be found under the Knowledge Check playlist.

I also have a library of shorter videos (less than 1 minute in length - shorts) that are quick math tips and tricks on basic math topics. Some of these short math help videos include problems that you can work on yourself and submit your answers in the comments. They are all listed under my Math Tips and Tricks playlist.

Improved math is creating more videos every day to cover topics from 4th grade, 5th grade, 6th grade, and 7th-grade math. The videos focus on fractions, basic math operations, geometry, and ratios but more topics are being added all the time. If there is a specific topic you would like to see covered, drop me a comment in one of my videos and let me know!

Free math help videos will be posted every Thursday and Friday. For additional math resources, check out my math help website at improvedmath.com where I post math worksheets and answers along with additional context on math basics.

Thanks for watching my channel.

Quantum Simulation Explained in 9 Slides Teacherflix 13 Views • 7 months ago

Quantum simulation is a really promising route to discover new technologies of the future by finding new materials with new physical properties. Check out the Qiskit YouTube channel here: https://www.youtube.com/qiskit and this is a good playlist to start with https://bit.ly/2KxqOIV

I’ve talked before about how quantum simulation is my favourite application of quantum computing, so I thought I’d make a video to explain why. And in this video, I run an actual quantum simulation on a real world quantum computer.

You can implement this specific simulation too with this video: https://youtu.be/Z-A6G0WVI9w

The Seven Years War and the Great Awakening: Crash Course US History #5 Teacherflix 18 Views • 2 years ago

In which John Green teaches you about the beginnings of the American Revolution in a video titled The Seven Years War. Confusing? Maybe. John argues that the Seven Years' War, which is often called the French and Indian War in the US, laid a lot of the groundwork for the Revolution. More confusing? Why does this war have two names? Why were the French and Indians fighting each other? The Seven Years' war was actually a global war that went on for nine years. I think I'm having trouble making this clear. Anyway, the part of this global war that happened in North America was the French and Indian War. The French and Indian tribes were the force opposing the British, so that's the name that stuck. Let's get away from this war, as it makes my head hurt. Other stuff was going on in the colonies in the 18th century that primed the people for revolution. One was the Great Awakening. A religious revival was sweeping the country, introducing new ideas about religion and how it should be practiced. At the same time, thinkers like John Locke were rethinking the relationship between rulers and the ruled. So in this highly charged atmosphere, you can just imagine what would happen if the crown started trying to exert more control over the colonies. The colonists would probably just rise up, right? We'll see what happens next week.

Why No One Has Measured The Speed Of Light Teacherflix 17 Views • 7 months ago

Physics students learn the speed of light, c, is the same for all inertial observers but no one has ever actually measured it in one direction. Thanks to Kiwico for sponsoring this video. For 50% off your first month of any crate, go to https://kiwico.com/veritasium50

Huge thanks to Destin from Smarter Every Day for always being open and willing to engage in new ideas. If you haven't subscribed already, what are you waiting for: https://ve42.co/SED

For an overview of the one-way speed of light check out the wiki page: https://ve42.co/wiki1way

The script was written in consultation with subject matter experts:
Prof. Geraint Lewis, University of Sydney https://ve42.co/gfl
Prof. Emeritus Allen Janis, University of Pittsburgh
Prof. Clifford M. Will, University of Florida https://ve42.co/cmw
The stuff that's correct is theirs. Any errors are mine.
