+ | :The "diagram to the right of the Epitaph of Stevinus", also described as "A weird diagram with lines in it", or "partitioning of phase space into fundamental cells", or " system of coupled pendula, often used in math physics courses to illustrate Lagrangian mechanics", can be described more literally: ''There is are two horizontal rulers with divisions 13 pixels apart and 17 pixels apart, respectively; and diagonal lines showing the correspondence between the first four markings of the upper ruler with those on the lower. The intervals seem to be labeled.'' Returning to speculation, I think this suggests an illustration of '''Length contraction (Lorentz coordinate transformation) in Special Relativity'''.

I don't think Randall put enough thought into those tiny squiggles for us to be able to use pixel-counting as a hint to which labels interpretation is more likely… but what of it? We can make up labels that fit any interpretation. I did say "Length contraction (Lorentz...)" was just ''speculation''. I do like the "four pendulums coupled by springs" idea, though the horizontals look too ruler-like to me. It might be better just to say "two horizontal ruled lines linked by some diagonals" !

Of course, each planck-time would require 2^(10^80) steps of simulation in the CA. If 10^80 isn't big enough for you, then just make it 10^1000 or Graham's number, or anything finite.

- Weird thing with lines in it

Could it have something to do with time dilatation? something like "real" time vs "observed" time (my first comment, hope I did it right) 108.162.241.82 20:49, 18 May 2017 (UTC)108.162.241.82

probably has something to do with relativity -- two objects moving, arriving at different points at the same time, or maybe a diagram of spacetime. 66.202.132.250 16:44, 10 June 2013 (UTC)

It's a Feynman Diagram 206.174.12.203 19:24, 10 June 2013 (UTC) Toby Ovod-Everett

- I did add the incomplete tag because this comic and also the explain is still really complex. More important: People without a proper physics background never will understand. --Dgbrt (talk) 21:01, 10 June 2013 (UTC)

There is a short story called "SOLE SOLUTION" by Eric Frank Russell which is quite similar to the one in the story. Just in case that matters. -- Maob (talk) *(please sign your comments with ~~~~)*

Re Rule 34 - the point is that this comic _is_ cellular automaton porn (as are the YouTube videos of Minecraft calculators and the like). Rule 34 works, bitches! 141.101.98.241 (talk) *(please sign your comments with ~~~~)*

Yo *calculus* is the latin word for pebble! I learned this and had to come straight to this page! ahhh connections! 173.245.50.88 Sawyer Biddle

As it turns out, Rule 110 seems to be a *really bad* way to simulate a universe- you would be much better off using a Cyclic tag system, since Rule 110 takes dozens of generations and potentially hundreds of cells to simulate one step in such a system, or a more sophisticated cellular automaton, such as Wireworld. --Someone Else 37 (talk) 05:12, 9 March 2014 (UTC)

To whoever objected to panel number references, does what I did with first words fix that? 199.27.128.99 (talk) *(please sign your comments with ~~~~)*

Well, that's a pretty unfair comparison in the last panel, the protag is immortal after all, if I'm immortal I might do the same thing, but hey we got a much shorter life to live 103.22.201.168 (talk) *(please sign your comments with ~~~~)*

The diagram to the right of the Epitaph of Stevinus looks like a system of coupled pendula, often used in math physics courses to illustrate Lagrangian mechanics.

- The "diagram to the right of the Epitaph of Stevinus", also described as "A weird diagram with lines in it", or "partitioning of phase space into fundamental cells", or " system of coupled pendula, often used in math physics courses to illustrate Lagrangian mechanics", can be described more literally:
*There is are two horizontal rulers with divisions 13 pixels apart and 17 pixels apart, respectively; and diagonal lines showing the correspondence between the first four markings of the upper ruler with those on the lower. The intervals seem to be labeled.*Returning to speculation, I think this suggests an illustration of**Length contraction (Lorentz coordinate transformation) in Special Relativity**. Mrob27 (talk) 20:22, 28 November 2014 (UTC)- That seems highly unlikely due to the top labels on this graph. In your explanation they can’t represent anything relevant. Also if this diagram is used to represent spatial contraction, it does not do a good job of it. 108.162.216.209 13:45, 1 December 2014 (UTC)

I don't think Randall put enough thought into those tiny squiggles for us to be able to use pixel-counting as a hint to which labels interpretation is more likely… but what of it? We can make up labels that fit any interpretation. I did say "Length contraction (Lorentz...)" was just
*speculation*. I do like the "four pendulums coupled by springs" idea, though the horizontals look too ruler-like to me. It might be better just to say "two horizontal ruled lines linked by some diagonals" ! Mrob27 (talk) 17:00, 1 December 2014 (UTC)- You are totally right, this one may always be pure speculation. Though I am pretty sure the bottom points are labeled w, the top is by no means clear. 108.162.216.209 20:46, 1 December 2014 (UTC)

I blatantly overlooked the exisiting sentence in the explanation. i blame the layout of this page. inline text that spans the whole available screen width is not pleasant to read on large displays ;) ...as for my English... the confusion stems from my bad keyboard/typing. it was meant to read "added notE about Cueball" for instance, or "as in A being stuck". 141.101.105.233 08:15, 13 November 2014 (UTC)

Who or what is Nugui and why is it relivent.108.162.216.209 17:57, 12 November 2014 (UTC)

is randall not assuming that his universe (and by implication ours) is finite? if not, one iteration of the machine would still take infinite time. --141.101.98.201 12:42, 26 November 2014 (UTC)

- I think it's good enough to assume that the universe is finite, but really really huge. Hypothesizing that adding one particle to the model requires twice as many cells in the cellular automaton, that means that Cueball's cellular automata rows could be about 2^(10^80) cells long, allowing simulation of a physics system containing 10^80 particles. Of course, each planck-time would require 2^(10^80) steps of simulation in the CA. If 10^80 isn't big enough for you, then just make it 10^1000 or Graham's number, or anything finite.

- Don't forget that Rule 110 has 000 -> 0. Cueball can just add columns on either side as his universe expands, consequently taking more and more time to compute steps as the number of columns increases. 108.162.216.42 (talk)

Did anyone notice that the binary numbers pointing to the particle are both 42? 108.162.241.16 19:26, 27 November 2014 (UTC)

Just as a curiosity -- there is a somewhat similar concept in "Permutation City", a book by Greg Egan. 141.101.88.211 (talk) *(please sign your comments with ~~~~)*

I don't understand how it's possible to simulate a universe this way. Assuming that quantum mechanics is correct, and some forms of particle decay are truly random, wouldn't it be impossible to simulate this with a purely deterministic system? KingSupernova (talk) 15:30, 1 December 2015 (UTC)

- The universe Cueball is simulating would have to conform to digital physics. I can't speak about the fine points of quantum mechanics, but observably random events in a simulated universe could be the result of a pseudorandom number generator with a very large state.

This is definitely my favorite comic. I just really love it - I wish there was a book or something about it that was more in depth. --108.162.219.5 14:32, 5 June 2016 (UTC)

- Yeah. Wow. Just... Wow. I would be so interested if this were somehow true. I just wish he could occasionally figure out how to mess with our retinas by spontaneously flipping bits in order to make us see a representation of him. That would be awesome, right? If I can make my own universe, well... I would do that. Also, I love this guy, real or not. That's right, Jacky720 just signed this (talk | contribs) 16:10, 5 January 2017 (UTC)

I was thinking the whole "eternity in a wasteland" was just a Calvin and Hobbes type fantasy that the bored student conjured up to describe how he felt about this class. ~~ Jelsemium

This still isn't anywhere near as big as 3^^^3. Mathematicians are very good a making big ass-numbers. ~~ Schrodinger's Wolves

There should be a short story about this. Fav comic by far, and got me interested in philosophy lol --162.158.62.181 19:13, 17 July 2020 (UTC)
