@renard6012

3 жыл бұрын

I was about to disagree with that statement, mainly as a knee-jerk reaction, because efficiency in design inherently has a beauty on its own. It may not produce rhythmic sounds, or have good-looking patterns, or even look interesting to the naked eye, but a well-designed integrated circuit is beautiful, as well as a plane that flies well, or any other simple and elegant solution to a problem. May be my inner German speaking or something, but there is an undeniable beauty in efficiency, a great satisfaction in seeing the best possible solution to a problem... Why then I do not disagree at all? Because there is one human activity strongly associated with beauty that is, speaking on a purely utilitarian term, an utter waste of resources: That activity is PRODUCING ART! Art is probably the opposite of efficiency. It has zero utilitarian value, and still, it has existed longer than engineering... or probably art and engineering have coexisted forever, because the beauty of engineering comes from its likeness to art: Rhythm, for example, is something humans really like. The basis of music is rhythm, and a pleasant and beautiful thing machines tend to do is producing rhythmic sounds... In rhythm we can find the beauty of a well crafted machine, because an engine with a problem will not produce rhythmic sounds. Electrical equipment on the other hand produces monotonous hums and is not pleasant to listen to. Nobody finds beauty on the sound of electricity. I consider the best testament to human ingenuity the ability to take the beauty of efficiency and the beauty of art, and combine them into one single design or machine. As you can imagine, I really, really like watches, and clocks, and engines, and trains, and railways, and propeller engines...

Electrical hums can harken back to that view on perfection and can even be seen in modern EDM music with droning undertones that act like bass and texture to the notes on top of it. Nevermind the fact that people play music with pure electricity with Tesla coils so even the sharp unpleasant noise of electricity can make music as well.

Every other youtuber: I cant think of a video idea so I'll do a vlog. Wesley: I cant think of a video idea so I'll reinvent the Babbage engine

Main problem i see is friction. With enough gates in series you won't be able to move the inputs, since a single input will move the entire machine simultaneously. What i think would be better is to have a mechanical clock input. This input would be what drives the outputs so that all the inputs do is decide whether the "clock" makes the output move or not. For example the AND gate: set A -> reset B -> pull clock -> nothing changes set A -> set B-> pull clock -> output changes I'm bad at explaining my ideas but i hope you get what i'm saying. The only drawback with the mechanical clock input that i see is that you would have so sequence it. For example with your current design as soon as one input is changed the entire machine moves and the result is near instant, but with this mechanical "clock" you would have to strobe each section step by step, sort of like a wave traveling through the gates. But then if you connect each section to the clock but with an inverter in between each section your clock it should be enough to sequence your clock in a "tick-tock" kind of way. And thinking about it you only need two clocks i total, one inverted, the other normal and just connect every second gate to one and the rest to the other clock. Anyways do what you do, will be interesting to see what you come up with.

Great video - interesting concept, really well explained, loved the Doglas Adams quote. I'm looking forward to updates as you progress!

Electronic circuits have the same issue - a typical 5V logic chip will always see an input under 0.8V as a '0' and an input over 2.0V as an '1'. This leaves a range (0.8V - 2.0V) where the behavior is 'undefined'. (It may be off, on, or even weakly on or weakly off) Some amount of effort is put into avoiding this undefined range.

When you scale up your logic circuit, you might end up with a problem : push-pull logic gates are lossy, and after tens or hundreds of them it might push the final rods so little you wouldn't even be able to notice it. Rotational gates are harder to build (you need gears, sometimes complex ones, they can be made out of legos though), but they solve this problem. Although a full computer built with this will need a lot of torque. You might also want to look into non-logic gates operators that mechanics allow, a half-adder can be built with a single double-channel relay (while with indivitual logic gates you could need 3 or 4, maybe more), there's probably similar setups in mechanical computing

As far as the binary logic - that's cool. It would be neat if there was a simple mechanical implementation for a NAND gate, because that is all you need - every other type of logic can be build from NANDs

​@@oldmossystone I completely disagree with your blanket, and quite frankly derogative, statement. A statement that is just as shallow as you claim that the original statement is. Because: There would be no flute without the technology to drill holes in bones or forming wood. Not to mention metalworking, but that is much later. Body paint works as sunscreen, and extracting the paint and mixing it is also technology. That statue that always was inside that block of marble? It required many skilled hands to turn the marble rock into a block, and even more technology to create the tools used in all of the processes from extracting a slag of stone to polishing the final statue. Making a strict divisions between art, science and technology is dangerous. Art, including stories, have always inspired scientists and engineers to create new things, while new technology and scientific breakthroughs made new kinds of art possible. The links between technology and science most definitely goes both ways as well.

@@57thorns The implication in your original statement is that art is hidden and needs technology to reveal it. If this were true, all art would require technology to reveal it. This would exclude e.g. singing from art. QED. While various forms of technology can be exploited in the creation and dissemination of art, there is no essential need for technology in the pursuit of art. There is no need for a 'division' in order to make a distinction between technology, art and science either. Division would be bad, distinction is necessary in order to understand what each of them is, and to help us understand their unique value in our culture(s). Returning to your example of the Block of marble. The statue was not always inside the block. The statue is a result - a side effect - of an expression of the artists state of mind during that creative process. The important point here is that if there was no stone, the expression could still have occurred in some other way - the Block of marble is not the essence of the art. The statue itself isn't even the essence of the art - otherwise any statue would be art (clearly not the case, many are just ornaments with no greater value). The statue or song or painting is a conduit - a medium through which to communicate. A book is a useful analogy here. A book is a physical thing with pages and words. But the book is not the story, and the words are not the story either the story is an abstract construction of ideas that the reader decodes by reading the book. A statue is like a book, it is a medium through which an artist has encoded some abstract meaning. If the statue is art, it is because it contains some deeper meaning encoded by the artist well enough that it can be decoded by the 'consumer'. In the same way a story doesn't have to be in a book, it could be spoken word, or a movie, the essential meaning encoded in a statue could potentially have been encoded in a painting, or some other art 'form'. Not all available encoding forms require technology.

Well this is getting interesting, I work on turbine engine fuel controls for a living, essentially a hydromechanical computer, although much more analog than binary. Its impressive what can be achieved without the use of electricity, these take into account the throttle position, barometric pressure, temperature, and current engine rpm along with a few other parameters to meter the correct amount of fuel at any given time. And all designed in the era of slide rules no less! A digital system would likely be better, but they still do the job. I look forward to seeing where you will take this.

Great video! I was surprised you didn't mention hydraulic computers. Lots of older automatic transmissions are, very basically speaking, just sets of logic gates that are controlled using hydraulic fluid and vacuum.

Looks like a fun adventure! I imagine the resistances of the system are going to stack up pretty quickly though. Electronic circuits can be built with gain, to increase the strength of a weak signal. Can you achieve the same with your mechanical system? Where does the energy come from to do so?

Matt Parker built a calculator out of domino pieces. But it can only do one calculation. I guess the pieces hold potential energy which is good. Other people built calculators with "marble gates". You could let marbles roll down and then lift them up on several places to add energy again. Are marbles too slow? You could power each mechanical gate and only let the connected gates direct the energy instead of providing it on their own. That's how real electronic computers work, don't they? Maybe push some rod upwards and another rod can connect it to another gate or disconnect it, like a clutch.

This is a "CMOS NAND Gate": en.wikipedia.org/wiki/CMOS#/media/File:CMOS_NAND.svg It connects a high voltage / push to the output, if at least one input pulls and it connects a low voltage / pull to the output if both inputs push. So, in the end it "not-pushes" exactly if input a AND input b push, like a NAND gate should. (IDK if that helps anybody, sorry. I was pretty intrigued by that difference between the flow of the 1s and 0s and the flow of the voltage in computers when I first learned about it.)
