Did you know the reason quasi connectivity exists on java is because notch when trying to implement pistons copied the code of a door. Basically Pistons, Dispensers and Droppers can be powerd exactly like a door.
Yes./lh
the downstream effects are incredible, what some see as laziness i see as a miracle.
that explains. SO MUCH. thank you
So is this a bug? should they be symmetrical, would that be hard to achieve? does it even matter? lol...
@@wingdingdmetrius8025 Correct, it is a bug! But even though it's unintended, and rather unintuitive, it turned out to have some very useful applications - thanks to quasi-connectivity, many machines can be built that would simply never be possible if pistons were powered the way that, say, Redstone Lamps get powered. So it was decided that it would never be fixed.
That said, this is only the case in Java Edition. In the Bedrock Edition of Minecraft, basically everything was rewritten from scratch, and the developers of that version decided against deliberately re-creating the behaviour of quasi-connectivity. That, in addition to some other subtle under-the-hood changes, means that Bedrock Edition doesn't have as much potential for really fancy complicated machinery as Java Edition does.
14:18 "We should have a name for this family of rules
that defies your expectation of symmetry."
We often call contraptions "direction-dependent" or "directional"
if they defy rotation symmetries,
and we call them "location-dependent" or "locational"
if they defy translation symmetries.
So we already have some words for contraptions defying certain expectations of symmetry.
mmm yah. Practically, those 2 cover most communication needs and I cant have much hope that we'll get any amore fun terms. Though there isnt a common term yet for builds that dont work if you mirror them. But builds like that which are not also directional are rare. If we kept the naming theme, such builds are "orientational" but the math books I read use the term "chiral" I think
@@whitestonejazz Chirality dosen't quite capture it, as it describes structures, that can't overlap with their mirror image. In case of our piston, mirroing it in the zx or zy plane does work though. By chirality, I'd expect the functionality not to change if the whole assembly of piston and redstone is rotaed or mirrored.
To borrow a term fom music, I'd call the shown behavoirs dissonant.
Maybe "absonutivity" would be a good term.
I mean these things don't even have a common theme. Update preferences, for competing interactions, are completley directional (thus chiral, btw), items in a dispenser behave, like they have some kind of weight and quasi connectivity has an absolute direction (like the gravity in this world).
@@cahdoge what about stereo- as a prefix based on stereoisomers, molecules which are mirror images of each other and have different properties? I think it's a pretty fitting name.. I'd feel like a dissonance could be a correctional circuit that needs to be added to every machine except the first one in sequence.. or perhaps that machine would be "resolving the dissonance" haha
I'm probably the worst guy to comment on this. Math, english and physics were probably my worst subjects.
Is 'context' or 'contextually' the word your looking for?
@@whitestonejazz orientation dependent?
You mentioned "item physics tick skipping based on item ID", and I have never heard of that before. I'd love to see a video focused on that, it seems really interesting! (Or at least unusual haha)
Look up 2No2Name’s video on it titled “Wireless Redstone 2: The Game Mechanics”, which explains how it works and what uses it has. Hope that helps!
This is a really interesting topic, and I have a couple youtube videos saved about it, which I figured I could out in a list here. I think there's some others that explain what's going on well, and how to use it, but these are just the ones I saved:

@@gavin5410 Yo awesome! Thank you!
Not only do we in TMC try to understand the directionality of redstone, we often try our hardest to take directionality out of our contraptions or render it irrelevant in some way. In order to do that we use often use non directional elements of these redstone components in conjunction with update chains to ensure a devices function. Although when we refer to something as non directional we usually ignore rotations other that the 4 cardinal directions.
I loved the tie-in to QM! Reminds me of Noether's theorem, where any symmetry leads to a conserved quantity - and likewise, a broken symmetry seems to imply there's something that's NOT conserved (like how Dark Energy has been shown to actually violate energy conservation by breaking a symmetry).
Obviously minecraft isn't known for its "conserved quantities", like flying machines very clearly break some kind of conservation law but like I wonder if we'll discover some kind of specific exploit relating to the symmetry broken by quasiconnectivity. Or not, im kinda redstone-illiterate so idk lol
i like the word Quasitivity (quasi-relativity) for a description of minecraft's limited¹ symmetry.
one of the main things that breaks the symmetry is quasiconnectivity, so i think quasi is a suitable prefix to use in this case.
these are our properties:
- all machines are symmetric upon translation²
- some machines are symmetric upon rotation
- no machine is symmetric upon being given velocity³
special relativity was created to accommodate the fact that light has a constant velocity regardless of your reference frame and that we have no "universal" reference frame, that all inertial reference frames behave exactly equally, and there is no test you can do to determine your "universal" location, velocity, direction, etc.
considering we have about 1/2 of those properties present in minecraft, i think quasi-relativity is a good word to describe that, and i think Quasitivity is a catchy contraction of that word
¹ limited by directional asymmetry and inertial asymmetry
² except for a few that are based on other game mechanics, like needing to be in a fortress for a wither skeleton farm, you can't translate beyond that fortress and still have it work.
³ because minecraft has a fixed grid. you can make things that move, like flying machines, but those are part of the machine. you can't set a static component in motion and have it move, or push a flying machine sideways and have it drift diagonally while flying forward.

Quasality *mic drop*
Wow! Super helpful. As a redstoner-wanabee I really appreciated how well you explained quasi connectivity. I have been thoroughly confused by this for years! I cant wait to try out these flying machines.
You seem like a RUclipsr, who knows and understands flying machines very well. I and the Bedrock community would be happy, if you would also make these videos on bedrock, might also be a little of a challenge!
i understand minecraft physics very little but i'm still endlessly entertained by this video. thanks chris :)
This video blew my mind. In physics we have various names for direction dependent interactions or structures. For this case I like to think that direct redstone connection is spatially isotropic and quasiconnectivity is spatially anisotropic. Also this video makes me think what happens if you have a direct connection and turn it into a quasi connection automatically, and if that can be studied by spontaneous symmetry breaking. Great video, keep it up!
I see plasma and i already know this will be a great collab
*TRANSFORTIVITY* From "transform" a general use term for rotation, scale, & translation
This is useful and interesting! I have a challenge: 8x8 sand/gravel piston door, where you input a design, it prints the door, and reorganizes them back to sand/gravel. I'm working on this, but nobody would see it on my channel, soI'd rather you do it!
Dont give up on ur dreams upload it on ur channel! Maybe its ur break through!
Sounds like a similar mechanism could be used as a Connect 4 game that automatically sorts the pieces!
Yes, loving this discussion!!! I definitely lean to the more symmetrical Redstone components. I think the only one I use now thats _directional_ in the way you’ve described.., might be bedrock’s wireless.
This was very well put together! Good job explaining complex topics in a simple way.
Just as important in physics as the symmetries that hold are the symmetries that are broken, and when.
Both the symmetries demonstrated in this video are actually broken under specific circumstances in our universe. The mirroring (or parity inversion) changes the results of anything involving the weak nuclear force (including things like radioactive decay) because the weak nuclear force only interacts with particles that have left handed chirality. This only affects quantum physics though.
General relativity itself doesn't enforce time translational symmetry. The behaviour of the universe is different now than it was 13 billion years ago. This has some weird effects, like energy not being conserved.
A comprehensive study of the symmetries Minecraft physics has, when they're violated, and the effects these violations have could give some really valuable insight into how to break the game. I know of some cases where it already has, but there is surely more to discover.
Great video, but
When you want to prevent piston reextending you don’t really need a qc, just having 2 blocks in front of sticky pistons is enough.
Also when you work with vertical wires it’s nice to use sand for delay.
Turns out the vertical extension doesn't work in some orientations with only 2 blocks in front of the sticky piston (say slime and glass). The piston is apparently needed. Is this related to the fact that a BUDed sticky piston needs 2 blocks in front to stop bouncing endlessly?
@@whitestonejazz yes, this is the same mechanic.
In your case it’s probably because observer updates sticky, so you get a race condition, that’s why it’s directional
Try moving observers 1 block down, for example, should work
I thought you might find it interesting that the bedrock community uses the “piston brakes” to have flying machines work at all. not having block spitting doesn’t necessarily mean you can’t have flying machines ;)
absolutely insane
2:50 WOW i think i knew the behavior but THAT is a neat trick i hadn't considered.
11:10 this actually reminds me that mirror images of molecules isn't possible, reality has a handedness like minecraft, a symmetry lacking in physics.
I thought physics has CPT symmetry (charge, parity, and time). Veritasium has a video about it.
@@iteragami5078 there are many symmetries in the universe and situations where they are broken.
For example, conservation of energy is broken in 3 different ways: dark energy, the creation of a W or Z boson, and virtual particles
Well, you can produce mirror molecules
But your proteins would also have to be mirrored to do that. And there are a few molecules that are built mirrored, for example the molecule that makes the mint taste is a mirrored version of the molecule that makes the taste of rye bread.
Quasi symmetry feels fitting to me, though I can understand if people find it a stupid name 😅
I literally yesterday tried to make two way expandable flying machine.
The tie in with physics was cool. Reminds me of the leibniz-clarke correspondence in which Leibniz uses the principle of sufficient reason & his law of the identity of indiscernibles to argue against the newtonian absolute view of the reality of space (& time) in itself. A lot of it is how it would necessitate inexplicable design choices like what you get with the position dependent mechanics in Minecraft. Was kinda hoping to find a name in there to categorize those minecraft mechanics but i couldn't find anything nicer than absotivity tbh. Maybe "placetivity" or "localitivity" could work though since that's really what's going on, place or space or position in minecraft has properties to it which exist independent from the properties or mechanics of the things in it.
Beautiful
you are really good at explainjng this dude
Thanks. To be fair, a lot of what I'm saying is stuff I learn by making these videos
@@whitestonejazz Fair, and it shows, you relate completely alien rotational macguffins as relatable everyday ideas like wings and spears
why you are not more popular than mumbo jumbo
i think the point group of piston quasi powering is D4. it had a C4 rotation about z, 1 perpendicular c2 axis, and im just gonna say no mirror planes cuz i cant tell?
I heard quantum and just didnt know anything anymore anywhere
A command makro mod could be really useful for demonstrations with tick manipulation just saying ^^
What mod are you using then lets you speedup/slowdown the tick movement speed?
It's called "carpet mod"
@@whitestonejazz Thanks!
cool!
Hello, new fan, could you please tell me how you froze the game and stepped forward 1 tick at a time? I can't find anything on Google about it, I'm trying to learn redstone and I think it would really help.
It's a mod called "carpet mod". I'm adding it to the game with a tool called "fabric"
@@whitestonejazz ohhh okay thanks!! Super fast reply too I appreciate it!
