The Action Lab

@InHumaneShape 🤣😂

Why are you on X when you could be doing this?

@jizaymes Yep that’s me…that’s frustrating

I can only guess that they put a line through the video so they can post other peoples content uncredited Isnt this @theactionlabman ?

@Rainmaker1973 What are you even talking about “plexiglass, water, lenses”, it’s just mirrors. Did you even watch the video that you took this clip from?

For around $150, plexiglass, water, lenses, and ordinary mirrors, professor of Physics at the University of Rochester John Howell built an uni-directional optical cloaking device. Here's a demonstration from a clip by The Action Lab.

@kk6vxx That is awesome!!

@theactionlabman I made a 2 bit computer with 3 bit display based on 1 half adder + 1 full adder.

I made the blackest car! youtu.be/43OGgDaR2aE

@DejanVinkovic Great job! It will help to get it started if you set the magnet on a big chunk of aluminum or copper to damp the unwanted vibrations (eddy currents will slow it down). Or even hold it on your hand loosely .

Magnetic bound states - a rotating magnet can trap another magnet into a stable configuration. After I saw this on @theactionlabman, I had to try it immediately! It took some patience, but it worked. The key is to tilt the rotating magnet slightly.

@csumac It is called LIT :)

@theactionlabman could you please provide rechargeable LIT paint name used for bright room episode?

The Youtube channel ActionLab published a video based on a setup developed by Daniel Paschall and me which can hold two floating magnets at each side of a rotating magnetic assembly aimed to show the binding functionality of the nuclear strong force. youtube.com/watch?v=Rx4lNi…

@AvionicsKen It doesn't actually slow down in a medium, the wave front appears to the electromagnetic fields and emissions of the atoms in the material.

@theactionlabman My understanding is light will slowdown in a medium, & has been done in experiments. What I dont understand is the notion the light will return to normal LS when it exits. How can the light get faster. Where does the engery come from to accelerate the photons?

@Chris_Stephan No it is not the marangoni effect in the clouds. It is due to the temperature differences at differing elevations and the size of the water droplets.

We are taught gasses do not exhibit surface tension, but the multilevel near perfect separation in different cloud formations really makes me think I’m missing something here. Thoughts?

@theactionlabman I was using your fluid dynamics video on the Marangoni effect to discuss surface tension and how it differs with different fluids with me 9 and 5yo…

@AvionicsKen It never actually changes speed. It is just the apparent wave speed that changes speed as the electrons in the material respond to the electromagnetic waves and then release their own. Electromagnetic waves always propagate at the speed of light.

@DevinBost @YouTube @BradStanfieldMD Ha ha that's a better thumbnail than my own!

I found an entertaining data consistency bug on @YouTube that combined the heading of a physics video from @theactionlabman with a picture from a video of @BradStanfieldMD. Looks like a request for help from aliens. 😂

despite the high cost of living, it remains popular

Go BYU! It’s not cold fusion but sounds just as good! Let’s see if this actually leads somewhere ksl.com/article/505050…

@johnny_weed It was an iphone

@theactionlabman Hi. I really appreciated your video where you captured the sound of light and I was wondering what kind of microphone you were using. Thank you! #science #theactionlab

But I’ve made some pretty sweet spreadsheets

Oh how true

@clown_depot When going to click on the like/dislike button everyone needs to flip a coin and if it is heads they like the video, if it is tails they dislike the video.

For 12 years on this YouTube video, there was a communal unspoken goal to keep the likes and dislikes completely balanced, which was always shockingly followed. In 2021, YouTube removed the ability to see dislikes publicly, which makes this tradition impossible to keep.
