Everyone knows atoms are really tiny. But just how small are they? After putting the scale of the universe in perspective, Wren from Corridor Crew channels his inner Vsauce, illustrating the relative size of atoms, quarks, molecules, and cells by scaling them up to something a bit easier to comprehend.
THE BEST Learning
Do you know what’s beneath your feet? Go deeper than the dirt and the rocks and the water, and you’ll eventually get to the Earth’s crust. This great infographic video from Dr James O’Donoghue (@physicsJ) and Dr. Christine Houser (@seismodoc) illustrates the materials comprising the crust, as well as their proportions.
Everything we knew about mudskippers before today, we learned from The Ren and Stimpy Show. Now ZeFrank is here to set us straight on these unusual fishes that can live both in the water and out. If there’s any creature that shows how evolution works, it’s this funky little dude.
(PG-13: Language) “Please remember, I am making none of this up.” We all know about Santa and Krampus, but in Europe there are other Christmas folklore characters that are not so popular. Why? Because they belong more to Halloween, as Sam O’Nella University explains.
If you follow them on any regular basis, you know that Kurzgesagt is mostly focused on videos about science, the future, and the nature of our universe. But this time, they offer up a clip that is more about improving our lives in the here and now, looking at how gratitude works, and why it’s so important for us to embrace it.
In the first episode of his series “Reservations”, CGP Grey explains how the Europeans who took over America slapped a label on its indigenous people that would later be thought of as offensive, yet is still commonly used within tribes. Plus, the term selected to replace it has stirred controversy for other reasons.
Whether it’s a bee sting or a kick in the groin, pain sucks. But we need these unpleasant sensations so we know when something is wrong or when to avoid danger. Life Noggin explores the nature of pain, and some conditions which prevent people from feeling it.
It’s a requisite stop for every kid with change in their pocket. But have you ever wondered how dropping a coin into a gumball machine makes it dispense a chewy treat? Animator and explainer of things Jared Owen gives us a detailed breakdown of its mechanism.
If you find space science fascinating, check out this clip from Kurzgesagt, in which they explain how neutron stars work. These phenomena may only be a few kilometers in diameter, but have an insanely dense atomic nucleus and powerful gravity, thanks to their origins as massive stars which have collapsed and gone supernova.
There are lots of things to be frightened of in the world, but is there a universally worst terror for all people, regardless of age, race, sex, culture or other attributes? Michael Stevens of Vsauce digs into the notion of fear, and how these unpleasant feelings are triggered in our brains. He also hates purple squares now.
Back in the 1950s, a new method of transportation was in development. The Fairey Rotodyne looked like the offspring of a helicopter and an airplane, and could take off and land vertically. But fast as it appeared, the Rotodyne vanished. Mustard takes a look at this unique aircraft, and why it never got off the ground.
It’s a terrifying thought, but in the interest of keeping us educated about the dangers of nuclear weapons, Kurzgesagt is here to teach us just how awful it would be if humans ever were ever to detonate a nuclear weapon in a city. Even worse, we actually did this to people back in WWII.
During WWII, Oak Ridge, Tennessee served as a facility for nuclear weapons development, housing nearly 75,000 people, all while managing to keep the entire existence of the town top secret. Half as Interesting explores the fascinating history of this small southern town.
“There are more phages on Earth than every other organism combined.” Kurzgesagt takes a few minutes to educate us on the finer points of the bacteriophage, a type of virus which is constantly killing off billions of microscopic organisms all around and inside of us.
Ever wonder what the quietest and loudest sounds in the universe might be? With the help of their imaginary robot Noisy, and Microsoft’s anechoic chamber, Bright Side digs into this question, and some of the science behind the way sounds travel and how our hearing works.
While jet engines do have the ability to reverse their thrust to slow down, or even taxi backwards, it’s not possible for an airplane to do the same in the sky. Bright Side provides a layperson’s explanation of the physics and safety issues that prevent this from happening.
While you might think that origami was exclusively an art form, engineers are taking inspiration from the paper-folding craft to create innovative designs that can shape-shift to fit objects to into smaller spaces, and enable compact mechanisms, while decreasing the number of parts used. Veritasium explains.
In a just barely Halloween-themed episode, musical expert 12tone walks us through the complexities of distortion, and what it is about such sounds that make them more creepy and off-putting than others – sort of like the way he draws from right to left across the page.
