Ooo - first submission and I've botched it. Better to go directly to the guy's site: http://trafficwaves.org/

You beautiful zen traffic wave surfer you. This, a thousand times this. Somewhere on the web there is a great video of a guy doing this pretty effectively. I guess it's maybe five years old now but worth a watch. I think this wsj vi

When you say: "we cut regulations, which ends up hurting people and which companies take advantage of" Think of this: Companies take advantage when no other company is around to out compete them. This is why it's so importan

Thanks for pointing that out. I'm a 1st time patreon thanks to you. This video jiggled so many good mathy connections.

I think I need to quote guy who inspired 3blue1brown's video now too: "Physics is like sex: sure, it may give some practical results, but that's not why we do it." R.P. Feynamn, you are missed.

And there is also ``form parameter design'' for ship hull geometry. It is also generative, but perhaps it more typically makes use of deterministic (nonlinear optimization) solvers to generate the geometry itself. (Implementatio

In case anybody is reading this post and wants an idea of how to get started with the basics of logic programming (upon which one might build toy constraint solvers) I recommend this: https://codon.com/hello-declarative-worl

Thanks for the details and big picture. Very nicely put.

I went to exactly the same post on Carroll's blog in response to the parent comment as well! Quite relevant I thought, given the comments about conservation laws and the especially the mention of dark energy that followed. -I elected

I'd like to point out an apparent oddity - that I, as a free market libertarian, agree with you that rolling back recent banking regulations is likely to lead to greater levels of exploitation of the populous by the banking/financ

I'm just a numerics person but I'd love to hear your input about relational/declarative/Prolog-like programming in Python in the following situation: if the working language doesn't have to be anything resembling Pr

First up, I am no expert, but I have traveled this road for a while so I'll share a bit. I see Susskind's theoretical minimum is plugged here. Good. That is a fantastic place to start. Start at the beginning. Skip nothing. Lev

Right on! Gods bless the humble triangle, bane of charlatans. (it's been a long night of polishing the thesis and now... scotch... I'll see myself out.)

Here's a piece of speculation. If you have no time for these harsh words, I'm sure you have your mouse at the ready. I am sorry you cannot crumple the page and toss this into the wastebasket if you'd like. Anything except

About bitcoin I would hazard to say that different assets change in value for different reasons... Bitcoin is a mostly speculative vehicle, right now, and goes up and down according to expectations. I want to stay away from it to avoid mu

The ill which inflation brings does not manifest itself in the short run. Inflation is a hidden transfer of wealth from everyone to first receivers, and first users of the new money. When the money is loaned into existance, the first reci

Interval Newton is probably my favorite algorithm. Intervals in concert with the fixed point theorems - amazing stuff. (and all the rest! - contractors, inclusion/exclusion tests exploiting derivative info, etc.) Good tools for opti

Yes indeed! (to this stuff being around a while) And then what it can do is a subset of the interval toolkit (also around a while). Somehow I get the idea that interval methods are underappreciated and thus lesser known - it seems anecdot

Well said. And it got me thinking. -I wonder if this article is well known: http://www.defmacro.org/ramblings/lisp.html If not then people might enjoy a deeper dive into this kind of thing! For anybody who's no

Okay cool. I take your point. Maybe you are right, but I'd argue that the first option actually applies to gauge theory in the following way: First, I have to assert that Lagrangian formulations of standard physics are generally simpl

Good point about charge conjugation symmetry vs "charge conservation"- I was totally mixing up one for the other! Thanks (a lot) for driving that home. For anyone who might follow this - C in CPT - is charge conjugation - the sw

Okay I can't resist - this stuff is just too cool. Here is my take on some of this stuff; assume grains of salt throughout as I am an engineer of sorts. (And sorry if this is old hat - and that the direction I go in strays pretty far,

Ah, you're looking for charge I think. https://en.wikipedia.org/wiki/Charge_conservation The whole thing spins my head around differently every time I try to learn more but I hope I am helping by pointing this out

In principle, I am right with ya. We need ways of beating (or at least coping with), the diffraction limit. It's fun to think of, say, stuff like this: https://arxiv.org/abs/1604.06351 (as far as big lenses go)

Aren't Google, Amazon, and Facebook examples of the dynamism we want to foster? Facebook and Google hardly "do" anything, in past senses of the term "do". In other words: are Facebook and Google really part of the
