I'm Brian Haidet - PhD in Materials Science, but I'd also describe myself as artist, maker, and Hawaiian shirt enthusiast. On this channel, You'll find my side projects and favorite physics demos - I hope you enjoy!
You can mix 10 marbles until they sort themselves. Why not 100?
This is a sequel to my last "ink tube" video, but this time I explain the title of the project, "the entropy of mixing". Entropy is a super weird topic, so I hope this makes sense, and I hope you enjoy!

Watch electricity hit a fork in the road at half a billion frames per second
Просмотров 2 млн6 месяцев назад
In this video, I measure a wave of electricity traveling down a wire, and answer the question - how does electricity know where to go? How does "electricity" "decide" where electrons should be moving in wires, and how long does that process take? Spoiler alert - very fast! I've been very excited about this project for a while - it was a lot of work to figure out a reliable way to make these mea...
An intuitive approach for understanding electricity
Просмотров 1,1 млн9 месяцев назад
In this video, I try to explain electricity Ohm's Law… using a LOT of different demonstrations and analogies. I've been working on this script for like a year and a half now - this took SO long to assemble because electricity is an absolute pain to learn and to explain. I crammed every analogy to describe electricity I could think of into this video (which is why it's... oof... 40 minutes... wh...

How does electricity find the "Path of Least Resistance"?
Просмотров 1,5 млнГод назад
Ever wonder how electrons know where they are going? Electricity is a pretty mystifying topic, because electricity seems to be able to do impossible things, or at least things that don't make sense at a normal "human" scale. In this video I use a thermal camera to show electric current through a maze made of aluminum foil. The electric current very efficiently solves the maze, which is awesome,...

Do you ever wonder how lasers work? What makes them different from other sources of light? The answer "stimulated emission" is frequently given, but even more important is achieving "population inversion". In this video I try to explain both, starting from ground level (no pun intended). Specifically, I describe the functionality of my cnc CO2 laser cutter. I also show off a woodblock printing ...

You're like a very, and I mean very, stable and laid back version of Styropyro. Or perhaps, he is you crazy scientist brother.
well for a fact its not electrons its the EM field you capacitated the field and the field do the magic, electrons are slow pretty slow,
Very very good demonstration and explaination
This comment will never be seen, but would be cool to see this experiment with EL wire instead
"trying to send too much current first". Yes. Like a discharged capacitor would draw more amps at start ... (Wait, what, a pair of wire acts as a capaticor? Yes it is ...) Great video BTW, Thank You for making it!
I think its C. ( Is that how grounding wires work?)
This proves you should take your batteries out of your devices because of the passive flow
24:12 Great that you emphasized inertia, that was my intuition here as well, it makes for a crucial difference between how water molecules and electrons behave, even though everything else seems analogous. Awesome video btw! Thanks for all this work!
What the fuck
Okay i just got to 10:55 What the FUCK
10:45 Live footage of your nightmare
This a load of rubbish, electrons do not travel. Go back to school!
It’s the definition of current. I was in school for a long time
It seems like thermodynamics shows that evolution is highly unlikely but has happened with regular frequency 😂
Evolution doesn’t have much to do with entropy at all - it has its own driving forces and an abundance of free energy
@@AlphaPhoenixChannel every system has something to do with entropy or it cant be a law.
The same wave phenomena applies to sound waves, as used in medical diagnostics and in technical testing. When a fast changing pressure pulse is exerted onto an interface of a material, the change in pressure travels at the local speed of sound. When hitting another interface, like a fissure, or the other end of the material, the wave is being reflected according to wave physics in a conservative field. Partly, the wave may travel through the interface, even at a higher pressure amplitude than the original one, which is what was really difficult for me to explain to people, to whom I was teaching ultrasound applications. Amplitude of pressure (analog to voltage) is not the same as energy-flux. It depends on the local impedance of the wave.
high end network test equipment can very accurately measure the length of conductors in a cable even when there is nothing connected at the other end, I knew they do this by measuring the reflection as we need to manually enter the specific cables lab tested % of speed of light (can vary significantly due to copper purity). great to visually see how this actually works explained so coherently especially considering it is something I use most days.

Science People being really good at Science, and really bad at science communication, again. Don't get me wrong. I like it and I subbed, but quality explanation really is rare amongst us. Fascinating.
16:17 the concept also works if you think about it as how sound waves move but are slower then light
10:53 it would be cool to see this same experiment done with influencers like adding a Magnetic Rod, A iron or faret rod, and a aluminum/coper or golden rod in different locations! That might give a better sense of how the magnetic field that is generated influencers the electrons interact!
Basically a rod that blocks the interface like Lead, a rod that neutral farrit material, a magnet rod that already has a field weak or strong enough that would/not be overpowered by the generated one, and a rod that would take the magnetic field and flip it by inducing a magnetic field in the rod such as copper/aluminum! Also if you replace the battery DC current with an AC one would change the frequency or flip of the magnetic field! It too would change how the voltage changes across the experiment and how fast the AC changes direction possibly show some insight into why this affects the power/volt over time.
Dude, I love your videos. You keep my passion for science alive and well!
Thanks for the research, now i didn't have to try the same thing, i have been thinking of doing something like you did with the wires. i might be kindof odd but too many analogs for me, you explained your thinking very well without the analogs :) Well done :)
This is most likely the best possible model that i've ever seen. I wen't from crying over circuit theory to designing PCB's in less than a month due to this model and understanding. it isn't perfect but its SO DAMN GOOD. this should be required viewing for all engineers and physisist. Honestly this could be used in highschools
uau, não tenho palavras pra descrever, a mente se cala perante coisas extraordinárias

A SUPERB presentation. Absolutely brilliant. Thank you, for all this work you did to create this - and for sharing it. I'd always taken this for granted but never had any notion of what actually happens.
great video

When I was a kid I used to look at turbulence by dripping fluorescent dyes into water & photographing it...I wonder how your turbulence machine would do with those? If it can filter ink it might do fluorescent dyes too....maybe try it with fluorescein, eosin Y, rhodamine, etc? Once when I was in high school I jumped into the diving pool with a plastic bag of fluorescein which created a glowing green pattern of turbulence....too bad the coach didn't appreciate it and turned on the pool filter...the most amazing part of the entire adventure was how quickly the filtration system disappeared the dye!! Amazing set-up, thank you kindly for your video!
PS: Try polarized light + filter illumination as well as UV and various colors too...cheers!
So what you are saying is that electricity is magic. 👍🤣
Also, I've always had difficulty with the fact that electricity moves from negative to positive, but it's only fairly recently that was changed from positive to negative (all the text books had been written!). So we all think the latter, & work with that.
So hooking up wires to the battery even if not connected will drain the battery a tiny bit. Have you tried to put a cup at the end of the disconnected wires? Was able to fill two cups of elections from a 9v battery. Tastes just like chicken!
Love it! Nice job.
You also initally have inductive and capactive reactances involved in the circuit you also must take into account the scope cables and the load of the scope which adds reactance to the circuit as well.
You do realize that the resistance of your load does not match the resistance of your source, the battery. The resistance of your battery is far higher than that of the load including the resistance of the wire, which is not 0 ohms but is so many ohms per unit length.
Impedance is resistance in an AC CIRCUIT. You will find in an AC circuit that the waves continue to "reflect " backward and forward until the impedance of the load matches the impedance of the source normally by changing the impedance of the load , but there are other things that has to be taken into consideration like inductive reactance as well as capactive reactance.
Stellar demonstration and analysis - I think you got the length/density ratio of the video's content right on the nose too. Would be very curious to see the scripts that went into this - I'd be quite curious to explore adapting them to work with my own equipment to explore this first hand myself. Inspiring!

T Boltzmann: entropy almost always increases
It took my dumbass 12 minutes to realize I didn't understand a damn thing this guy was talking about. I think the disconnected (open) circuit sent electrons through my eye holes into my brain and out my ass so fast that it caused my tongue to wrap around my eyeballs until I couldn't see what I was saying or this fellow either. So I stopped drooling, put my tongue back in my mouth picked my chin up and moved on to a different channel wondering if I'd just experienced a flashback from my window pane (acid) years back in the late 60's - early 70's 🎵🎵🎶Sunshine came softly through my a-window today🎶🎵🎶
Bravo! It was so cool to watch you do critical analysis with such a rudimentary setup. Really engaging presentation of your results. Subscribed. 😊
very impressive !!
Really cool, thanks!
Is the pressure mediation just stabilizing as I had imagined that electrons actually do not flow as we understand them but meditate between space and counterspace making the speed of light null or instantaneous? I also thought that the pressure mediates in the form of twisting pairs of Bierkland currents in electromagnetic waves around the wires?
I spent more time fast forwarding then watching this, i didnt need the same explination 6 times.
Fantastic video 👏 thanks for the lesson
This proof that order started from caos? like aminoacids was formed from random atoms, and then combined to form the RNA and DNA molecules, kind of nano computers, and then life evoluted against this, from disorder to order?
Ney, I was a chemist bak then. PhD, papers including the Nature. We did study entropy in the second year in the U. > so, why visit my channel Well, I am curious how to explain the concept of entropy to a 5yo. Sure, I can throw some logarythms and hope that an ansamble of states sticks. That is not how it works.
i dont understand why electrons after the infinity resistor are still flowing
