5 Science Tricks w/ Explanation
Last week I posed a video with 5 awesome physics party tricks. This week, Jabril from SEFD came on to help explain the experiments as we test them out for the first time and work through some of the amusing kinks in the process.
How do touchscreens work?
How does a touchscreen work? Why can you text with your finger, but not with a q-tip? The physics of smartphones is a complicated and amazing mixture of engineering, physics, electronics and computer science.
The Ultraviolet Catastrophe
How did the field of quantum mechanics come about in the first place? The Rayleigh-Jeans catastrophe, also known as the ultraviolet catastrophe was a prediction by the Rayleigh-Jeans law that a blackbody would radiate infinite amounts of ultraviolet light. It wasn’t until Max Planck came along and predicted that light came in packets or quanta that the field of quantum mechanics emerged and uninte
5 cool math tricks ft. Technicality
Math can be fun when you play with the rules, use it to do everyday things like fast math for calculating tips, and do some math magic tricks! Plus, math is the language of physics. Check out these 5 fun math tricks with Alex from Technicality.
Can explosions work in space?
The most exciting SciFi movies have tons of space explosions. But how effective would explosions be in outer space with no atmosphere to carry the blast wave? Could a hypothetical explosion hurt you in space?
Impossible Zero G Skyscraper
What happens when you keep building a skyscraper higher and higher? You may run into some problems with the laws physics. The higher you build, the faster the top of the building moves around the earth, and you end up with strong centrifugal forces. What could possibly go wrong?
Solving crimes with infrared?
How can you use an infrared camera to see through walls? To inspect the scene of a crime? To catch a thief in hiding?! This cool device attaches to your smartphone and has an infrared/visible light camera combo that allows you to see the details of an object AND its temperature. It's physics!
How to control light with water
How fast is the internet? How fast can we send data? This easy DIY experiment allows you to control light with water! Drill a hole in the bottom of a 2 liter bottle, fill the bottle with water allowing the water to stream out the hole, and a shine a laser on the other side so it comes out the hole and follows the stream of water! Just like fiber optics, the laser beam gets bounced around, but stay
My dad was hit by lightning (TWICE!)
My dad has been hit by lightning twice! This is an interview with him about those incidents. Plus we chatted about the science behind a lightning strike, which it's so dangerous, and how to avoid getting hit.
Can you solve the burning stick riddle? ft Simone Giertz par
How can you time 45 minutes with 2 sticks that each burn for one hour?
Why aren't plants black?
Why are plants green? Is there a reason plants evolved to be green, globally? What does it have to do with the color of the sunlight coming down through our atmosphere?
Everything you should know about TRAPPIST-1 exoplanets
The TRAPPIST-1 exoplanet system has seven earth-like planets and is only 39 lightyears away! I am joined by Professor Adam Burgasser and Dr. Katherine Deck, both astrophysicists on the Nature paper to discuss the discovery of this planetary system.
The Unusual Formation of the Hawaiian Islands
Hawaii is known for its volcanoes, but most volcanoes on earth exist along tectonic plate lines. Hawaii does not! What causes Hawaii to form, and how is it related to the mystery of a magnetic bar code across the Pacific Ocean? Host Dianna Cowern chatted with geologist Noah Randolph-Flagg from UC Berkeley while hiking on the island of Kauai.
Can you solve the $20 riddle? ft SMBC Comics' Zach Weinersmi
I sit down with Zach Weinersmith from SMBC comics to ask him some physics trivia and logic riddles!
Oxygen is magnetic?!
Liquid oxygen has unusual magnetic properties. This demonstration with the MIT Technical Services Group and a crazy blowtorch demonstration on the curie point of iron share a glimpse into how different kinds of magnetism work.
Why outlets spark when unplugging - EMF & Inductors
When we cut the electricity to an inductor, we get a sudden intense spark across the switch. This is known as inductive kickback or a back EMF and is produced because of Faraday’s Law of Induction. Not mean to be tried at home! The inductor doesn’t want to change its current, so the change in magnetic field creates an EMF resulting in a high voltage across the switch. #PHYSICS
