I think it was Ethan Zuckerman who once said that Congress is ill-equipped and incompetent to solve this kind of problem and that we need to design systems that guarantee outcomes and cites Signal as an example. We need to have that mindset now: a clarion call to software engineers.
Visualizations like this truly highlight how much there is to be gained from viewing the 3D phase space, but also how much richness we miss in >3D!
(I wonder if there are slick ways to visualise the >3D case. Like, we can view 3D cross sections surely.
Or maybe could we follow a Lagrangian particle and have it change colour according to the D (or combination of D) it is traversing? And do this for lots of particles? And plot their distributions to get a feeling for how much of phase space is being traversed?)
This visualization also reminds me of the early debates in the history of statistical mechanics: How Boltzmann, Gibbs, Ehrenfest, Loschmidt and that entire conference of Geniuses must have all grappled with phase space and how macroscopic systems reach equilibrium.
Great work Shashank!
Do boycotts work anymore? I'm asking for an AI-protesting friend.
Really neat! Heat pipes also utilize capillary action (via wicks) for heat exchange: https://en.wikipedia.org/wiki/Heat_pipe
Modern Warfare.
Physics teachers may enjoy Madame Hyde (2017) : https://en.wikipedia.org/wiki/Madame_Hyde
In it, there are long dialogues on Fermat's principle of least time (https://en.wikipedia.org/wiki/Fermat%27s_principle) and Faraday cages (https://en.wikipedia.org/wiki/Faraday_cage).
I wished the movie dwelled longer on those subjects though.
Really cool! I see a resemblance to scratch. https://scratch.mit.edu/
There's a hell of a lot more.
Michael Faraday's "Chemical History of a Candle" is a very readable masterpiece on the subject, despite its age.
The Engineering Guy has done much to revive Faraday's work: http://www.engineerguy.com/faraday/
Brilliant and powerful statement. Kudos to Lichess. But this part:
Imagine if scientists kept the result of every scientific study to themselves. The same work would have to be done over and over again as everyone was forced to reinvent the wheel countless times to do anything at all. Instead, scientists share their work and collaborate which benefits all of us.
raised my eyebrows. If only it were true. Aside from paywalled journals, we don't have a centralized repositories of data in most fields, probably because a lot of it is proprietary (or intends to be) in the first place.
This is brilliant work. I've been playing with this for the last half hour and have found cool papers that I otherwise wouldn't have. To me, this has a great edge over google scholar and lens.
A wishlist:
1) To be able to share maps with fellow researchers, not as pdfs or bib files, but as a url to the map so that they can interact with it. I can see that a "share link" is possible for an article, but not for a custom map. Such a link could also be used to embed such maps on sites like how one can with plots from https://ourworldindata.org/
2) To be able to get more metadata like sponsor, country, etc. like https://www.lens.org does.
3) To be able to upload pdfs and annotate them. I can see why this is dicey, but if possible, would be great to see an integration with something like https://fermatslibrary.com/margins
It's currently in early access so it's free to use, and you don't need to create an account to get started.
I know software developers need to eat and totally respect your choice in making it a paid service in the future, but I will confess a deep desire for such a thing to be affordable, if not free.
So given that the Super League won't work, what then _will_ work?
It seems to me that innovations can come from two forces:
1) Fairness: Make teams operate fairly. Audit thoroughly, no slap on the wrist for violating Financial Fair Play, salary cap (I can dream can't I?), etc. Given how our society favors the capitalist over the regulator, all efforts on this front have amounted to mere asymptotic jokes.
2) Eliteness: Make the league the creamiest of the cream. Increase the magnitude of what happens when athletes with incredible talent are wedded with facilities that enhance and curate that talent. This was in fact the point of the premier league, but the Super league took it a step too far. The perception is that the "magic" in a game between Real Madrid and Manchester United (Goliath and Goliath) is more watchable than a game between Derby County and Manchester United (David and Goliath). Except that Derby County can win that game, have won that game, and the resulting dreams instilled in people (not just fans of Derby County, but fans of United) comprise the very source code that makes sports worth watching: a tale of the impossible that parallels and informs everyday life. Some men with $$$ in their eyes just don't seem to grasp that, for all their "finger on the pulse" bragging. Or they did, but felt that the source code could be rewritten and that's all that matters.
The "Eliteness" front tries to maximize the quality of a sport just short of steroid use: story of the goose that laid the golden eggs. But what about fairness? How can we set up incentives for that?
Everything in life has turned to spam.
Why do we do this to ourselves?
Thank you!
I'd like to do this. Can you recommend a good starting place to learn how?
Yeah. I've seen it in an old BBC documentary: The secret life of machines - Internal Combustion Engine https://www.youtube.com/watch?v=gfr3_AwuO9Y
Very neat!
For a deeper appreciation, check out "The Algorithmic Beauty of Plants": http://algorithmicbotany.org/papers/#abop
Roger Penrose devoted more than half of his doorstopper of a book "Road to Reality" to complex numbers in which he uses Riemann surfaces to visualize the complex-number fabric of Reality™: https://openlibrary.org/works/OL3474173W/The_Road_to_Reality...
I was interested in plotting these Riemann surfaces and wrote a little article about it sometime ago: https://honeybee.freeddns.org/Visualizing%2520roots%252C%252...
Looks great! LOL at the "Knuth is my homeboy" picture!
Dead link that. Should let the author know. But there's a link at the top of the page as well: https://zyedidia.github.io/literate/website-source/
Not much in principle. It is just that literate is language agnostic whereas knitr seems dedicated to R.
Really neat! I can use this for CFD simulations where geometries need to be optimized; OpenFOAM should snap on to these stls just fine! https://www.openfoam.com/documentation/guides/latest/doc/gui...
TIL! Thanks!
How can one tell if the books are being uploaded somewhere or not? Can this work offline?
Can someone tell me, a longtime a gnuplot user (http://www.gnuplot.info/), when I'd want to use ggplot/plotnine?
Is there a sort of Turing completeness among plotting programs, i.e. can everything ultimately be done on any popular plotting program, or are there things achievable only in some and not others?
My OS is arch linux. It seems like the app does not use xdg-open (https://wiki.archlinux.org/index.php/Xdg-open ). Setting the BROWSER environment variable also doesn't seem to work. I don't know any other way to set the default browser.
Really nice work! I'm playing with the app currently. Is there a way to set the default browser used to open links?
A very useful application of quines: https://tiddlywiki.com/
Learned about it first from Joe Armstrong: https://joearms.github.io/#
A picture language equivalent can be found here: https://git.elephly.net/gitweb.cgi?p=software/guile-picture-...
I'm currently doing this and am in the middle of chapter 3. So far, everything has worked fine with guile.
