In the variant at the bottom of page 1, a 2-sphere capacitor drives the current. As a TLDR, does the 'displacement current' in this capacitor contribute anything to the forces on the wire elements?

Every prime past five ends in a 1, a 3, a 7, or a 9 — and for two hundred years those endings were treated as pure noise. In 2016, two mathematicians at Stanford ran a count nobody had bothered with, and found the primes quietly breaking their own randomness: a prime ending in 1 is followed by...

Something to do with -1/12 ?

"In this video we explore the many uses of electrolysis unlocked by inexpensive ion exchange membrane technology". Lots of interesting electrochemistry experiments that can be done with readily available items (although demanding plenty of patience to implement) This is one of those longer...

Separatrix : A dominatrix who separates clients from all their possessions.

I have installed ngspice (RPi-5), but haven't got around to experimenting with it. However, it's possible to do thought experiments and refine one's ideas while doing other life stuff. This has led me to discard the idea that there should be a momentary increase in disspiation exactly while the...

Yes, that is what I was vaguely trying to articulate. The waveform in baluncore's post is interesting because superficially it looks like a square wave with ringing after each rise/fall. However, the ringing is a growth rather than a decay. This has to mean either (a) the energy in that...

Can you test the hypothesis that there should be a current spike in the positive resistance during the jump from one attractor to another?

Re. the discussion about 'reality' of this simulation. If I understand correctly, the beauty of this class of systems is that it is very robust against what would usually be called simulation errors. Of course the quantitative behavior is in any case highly dependent on initial conditions. But...

Is the energy dissipated, or is the energy transferred to another element than the one whose voltage is plotted?

Dr Chua reminsces about the invention of his circuit: https://www.chaotic-circuits.com/wp-content/uploads/2015/01/THE-GENESIS-OF-CHUAS-CIRCUIT.pdf Page devoted to it (includes an interactive Javascript simulation page and how-to-build info): https://chuacircuits.com/

Yes, I guess I was framing my question like, "Is a needle more like a burger or more like a soprano?" One could make a case for both by stretching each analogy enough. :smile:

Got the join right away; got the tables thing only the next day.

I have been trying to understand intuitively why Chua's circuit should want to toggle between modes as it does. The aim is to internalize this concept the way a Steve Mould or a 3Blue1Brown might help me do :smile: Which is closer to the truth: (A) Rectification of the signal around one...
