Everything you should know about TRAPPIST-1 exoplanets

Originally published on Mar 1, 2017

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.

Check out this TRAPPIST video by PBS SpaceTime! https://www.youtube.com/watch?v=h871o…

How to control light with water

 

By: Physics Girl

Originally published on Dec 22, 2016

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 stays within the stream. Controlling light in this way gives up the ability to send information MUCH faster, as opposed to sending a postcard via snail mail!

Also found this great video by engineer guy who set up the experiment much better than we did:

Exploding soda cans with electromagnets in SLOW MOTION ft Joe Hanson

Making Music with a Tesla Coil: https://youtu.be/KGhNgeg9IAw

Watch a soda can rip itself apart in a fiery explosion at 11,000fps with a Phantom high speed camera. Running a current through a coil, produces an electromagnet. Turn up the voltage in this experiment, and make that current strong enough, and your electromagnet can rip a soda can in half. Or rather, make the can rip itself in half! This video was filmed at Arc Attack Studios in Austin, TX with Joe Hanson, Joe DiPrima, John DiPrima and Darren Dyk.

How the quarter shrinking demo works:
A coil of wire is wrapped around the quarter so it follows the edge of the quarter. Then a capacitor – kind of like a battery – is charged until it’s at a VERY high-voltage, which is then discharged through the wire. The current produced is high enough to make you go bye bye. The coil becomes an electromagnet – because current —≥ magnetic field But this magnetic field creates another current or set of currents in the quarter – because changing magnetic field —≥ current in a circuit. But moving charges, i.e. currents, in a magnetic field will feel a force. For the quarter, the charges moving in the edge are feeling a force inward. The current was SO strong that the quarter PULLED ITSELF inward! This is madness.

When you mix red and green, what do you get? White light is all of the colors, right? So, how do computer screens show you every wavelength of light? Or do they?

How 3D holograms work

 

By: Physics Girl

Originally published on Sep 15, 2015

Holograms are photographic recordings of 3D scenes. Unlike a camera, which captures one view through a small viewer focused by a lens, holograms capture an entire light field which allows them to recreate the 3D scene. Shimmery 2D projections, like pre-recorded Pepper’s ghost illusion, are often confused with 3D holograms.
