Another cool analogy is: You can take everything that was done here and replace the chains with oil lines, and have all the same logic applied hydraulically, or even pneumatically with pressure instead of voltage. The interesting dynamic of how it applies force to a motor for example: electrically you can spin a motor magnetically, where as hydraulic/ pneumatical systems can spin a motor kinetically. Electricity has volts/ current/ resistance, where as fluids have pressure/ flow/ volume, volume has length/ width/ height, a Kinetic system has mass/ velocity/ inertia, a magnetic systems has attraction/ repel/ conduction, a thermal system has temperature/ pressure/ conduction, a mechanical system has torque/ velocity/ friction, friction has pressure/ temperature/ velocity, states of matter have solid/ liquid/ gas, time has past/ present/ future, space has length/ width/ height, velocity has distance/ time/ vector (direction)... on and on; It's easy to see how many of these qualities overlap and how many systems shake hands with each other-- and that's without even stepping into chemical and nuclear interactions.

​@Infinity What can I say, I enjoy a good video!

Yeah, same differential equations for both systems. The two systems are called Duals.

yes, basically its all about Physics, theres not such thing in nature as Chemistry thats an artificial construct by man. Like there's no such thing that 2 dimensional object everything has at least 3 dimensions, 2D is for exemplifications only.

​@@ShiningForce07physics is also a construct by man, and maths is at the core of that. you can't reduce a discipline without adequate knowledge of it beforehand

A shock absorber is a frequency damper, its electrical equavelant is a capacitor...it smooths out the back emf oscillation in switching currents as to reduce arcing at switch contacts.

Just be sure not to use a cheap chain like that, or you might get a system error. A rubber band for wind-up motor shmafety?

im pretty sure mechanical computers exist and did develop for a time but they went out of fashion since electronics were cheaper to produce and more efficient

You spelled it wrong, mate. It should be FULL BRIDGE RECTIFIER!!!

Actually, it wasn't Turing's, but he indeed upgraded it and pushed to its limits. What is funny, is that something like 100 years earlier Charles Babbage invented a mechanical computer, but never got it done.

ah that's what the unibrow was for! I was very confused

The FULL BRIDGE RECTIFIER made me crack up, didn't see that coming

A common saying is "The map is not the territory." Every map is useful for something, and not useful for most everything else.

In Statistics, the phrase is: “All models are wrong; some are useful.” Credit to George Box for that one.

I came to that same conclusion a while ago about the universe. The truth is just the universe itself, and we are fragments of it experiencing.

Sometimes the thing itself is not even a 100% accurate model of all such things, due to natural variance. So, say you had a complete model of the human body, which would just be a human body, that could only be a single human body, which is not a complete model for every human body. So how could you ever get a complete model of every human body when each one is slightly different? Here, a model which is actually abstracted from the thing itself (the human body) could be more accurate in representing the totality of human bodies. This is making me think of the Platonic Realm of Forms.

@@Bayonet1809 Only the thing itself is a model of the thing itself, not other things, even very similar ones. Becuase, yes, your body and my body are quite different.

So naive. Electronic circuits were derived from mechanical devices. Do some reading.

lego technic needs to buy this company or at least access to their IP

@@alveolate There wouldn't be any IP protection when it comes to the basic components themselves. Spintronics itself is derivative work of concepts that exist in the public domain, you can't patent a sprocket or chain, nor one-way mechanisms such as clutch bearings and ratchets, etc. The only IP protection would be the book that goes along with the set under copyright, and how the set itself is modeled as you can't make a 1:1 reproduction. What use Lego would get out of these kinds of components are not covered by IP protection. Plus there's the blatantly obvious issue that these kinds of gearsets would have an insane amount of frictional losses if they didn't have bearings. Technic will never have bearings for quite obvious reasons. While it might be a decent idea, it just would not work in practice. Plus there's too many issues with how Spintronics approaches certain concepts, which results in bad analogies, something Lego would probably avoid when it comes to educational building systems.

did they tho

Bruh they regulated pressures through a combination of relief valves which are automatic, sometimes steam whistles which are manual and by putting less fuel in the firebox when u want pressure to go down and more when you want it to go up but they did not use these.

@@dog-ez2nu Or perhaps, as its steampunk, a steam engine. Could be the "battery" or sorts. Perhaps in this miniturised version a small steam turbine would suffice. Could also be a cool plot device that if steam pressure drops or the turbine is damaged in some way you end up with limited power, both spin volts and spin amps would be reduced. Which could result in reduced performance, slower computation, but also perhaps increased number of errors for circuits that require a certain range of timing to work.

Why did he do the mono-brow thing?

Probably can use mechanical devices for some of the logic gates AND, OR, XOR, NOT, NAND, NOR, and XNOR

The monobrow was the cherry on top

I did have the same subject, good times back then

It's the same thing because they share the same models/equations. Still in some areas (like thermal), they miss some components. Dynamic systems are everywhere in nature but some models (like transfer functions) are impossible

Sounds like you had a good control theory prof, must have been nice! Mine really wasn't so great 😕

Force voltage analogy , force current analogy

Sound like Ogata's "system dynamic " book 😂

Same😂 electroboom moment

Python2 or Python3 though?

Yeah, analogies help us feel more familiar with the actual works under the hood, while at the same time, getting some work done. They're not actual explanations of how reality actually works, but may be close enough to get our work done. Actually, I doubt we'll ever be able to really understand reality. It's too far beyond our capacity. All we'll ever have is closer, and closer, and closer, analogies... But the real truth will be hidden from us forever

@@zzzxhrg A meta-analogy seems in order. Maps are getting closer and closer to the territory, but the map can never be identical to the territory. Moire patterns in graphene lattice are analogous to sub-atomic phenomenon as well. This is mysterious. It seems it can help us to model some interactions, and maybe learn new things about sub-atomic particles, but we don't know if they're a perfect analogy or not.

I mean… did you think that anybody likely to be watching this video would be unaware that analogies are imperfect reflections of their subject? The only perfect reflection of a thing is the thing itself.

@@zzzxhrg Yes, words themselves are explained by other words which are explained by other words. We're always trying to explain what we mean, or what something means, because absolute truth is difficult when words cannot do what is required. I get a chuckle out of listening to Jordan Peterson stringing together sentences of $10 words, trying to explain his ideas in the most appropriate language.

Analogies are meant to convey information so the average can get some mental picture of what's going on. I use the "water in a garden hose" analogy to explain to people the properties of amperage and voltage. Most people don't know the difference. When I explain amperage is the number (amount) of flowing electrons and the voltage is the pressure behind those electrons, it clicks with them. Of course it's flawed but it conveys a message and gives a mental picture nature of electricity.

there's 28 transistors and 11 resistors so it'd have to be simulated probably.

@@satibel A 741 op amp would be easier. The resistor count drops to 20! (So still too complex to make cheaply!)

@@stevelknievel4183 any kind of operational amplifier would be great. To see it in action would make those winky foxes more understandable

I was confused about water tank being considered a capacitor, but I guess if you're filling it from the bottom then the analogy holds. idk why that took me so long to realize

I was lucky enough to do a GCSE course called "systems and control", which was half pneumatics and half electronics, and it was really interesting to see how you could do the same things in both, and even mix them together. In the same way as you can make a crude timer with a capacitor and a resistor, you can do the same thing with a reservoir and a valve, for example.

Im a biomedical engineer and we had a course where we learned to model mechanical fluid and biomechanical systems as circuits and differential equations

Funny … I had no issues understanding LC circuits but still struggle with mass-spring circuits 😂

@@ortzinator How many nuclear-warheads would it take to obliterate a fart? 🤪

Spintronics webpage clarifies it behaves like a FET

The closest concept I can think of in mechanics is buckling, which is the change in shape of a static element that is proportional to its second moment of area (moment of inertia) and inversely proportional to its length, squared. The higher the slenderness ratio (length:area ratio) a structural element (such as a column or an arm) has, the more likely it is to deform and potentially collapse. Likewise, a cable is very likely to burn up if an extremely high electric potential is passed through it. A bird's nest can be made of small branches and twigs, but a tall bridge needs to be made of tall, thick, strong columns in order to withstand the weight of heavy trucks and the destructive forces of earthquakes and cyclones. Likewise, thin, small wires might be good for cellphone cameras, but city power lines must be thick and large so as to carry large currents that will supply many homes and commercial buildings.

I didn't even think about how this would fit so amazingly into steampunk. Thanks for the insight!

Yeah, I had to do an experiment in Uni where we built a high-pass filter and I really didn't get how tf it worked, but this here is much more grounded (no pun intended) and easier to understand.

meta spintronics

Lots of things in physics, electronics, economics, biology, science in general, can be described with linear dynamical systems. Even more things can be described by non linear dynamical systems. Understanding these systems makes you extremely powerful.

The genius is not always in the idea, sometimes the genius is in how to turn the idea into a viable product

@@caiocc12 Also talent is not something innate. It's hard work and determination to keep doing and perfecting and adapting and perseverance until reaching the goal. That's what genius and talent is to me. It's determination and perseverance and hard work. I see determination, perseverance and hard work in these spintronic. That's why i'd say product is genius and people who made it were talented. Very same applies to this YT channel!

When I was a kid we had these 300-in-1 or 500-in-1 electronics boards where you could make hundreds of different electronic devices and experiments with all the supplied components that stuck into a big breadboard but they were very clever and designed for kids to be able to easily make electronic circuits. Of course back then RadioShack had a section in the back of the store with shelves of every electronic component that you'd want and anything else you'd need so I started making my own things, mainly trying to make my own synthesizers, a solid state guitar amplifier and distortion pedals but even with such an interest in electronics I moved on. We just don't normally take an interest we have as a kid and carry it into a career in adulthood.

Same. I used to disassemble and hopefully reassemble all my toys. I wanted to know how they "tick"

i think many kids did that. thing is theres more to it than i would have thought back then... mechanical stuff is much more understandable at a low level imo

Well this spintronic confuse me even more about how i though electricity worked i prefer the analogy of water going through pipes

The great thing is there's a browser based simulation on their website. It has a problem with floating point accuracy when dealing with circuits that spin really slowly, which can cause perpetual motion, but otherwise it's fun to play around with once you understand the concept

Hope this video led you to try it again

I suppose once you intuitively understand something, an analogy is just adding extra steps

I can see it being useful for demonstrating resonant circuits, but as soon as you start bringing in the differentials it becomes a lot more complicated.
