Unexpectedly and somehow contrary to my fresh posting about my plans for 2019, during the week of Jan 7-12, 2019 a new project appeared, which is temporary named Kaleidoscope. [Other names, until now: kaleidos, morphoo. Other suggestions?]

This post marks the appearance of the project in my log. I lost some time for a temporary graphical label of it:


I have the opinion that new, very promising projects need a name and a label, as much as an action movie superhero needs a punchline and a mask.

So what is the kaleidoscope? It is as much about mechanical computers (or physically embedded computation) as it is about graph rewrite systems and about space in the sense of emergent algebras and about probabilities. It is a physics theory, a computation model and a geometry in the same time.

What can I wish more, research wise?

Yes, so it deserves to be tried and verified in all details and this takes some time. I do hope that it will survive to my bugs hunt so that I can show it and submit it to your validation efforts.



Twitter lies: my long ago deleted account appears as suspended

9 months ago I deleted my Twitter account, see this post.  Just now I looked to see if there are traces left. To my surprise I get the message:

“This account has been suspended. Learn more about why Twitter suspends accounts or return to your timeline.”

See for yourself: link.

This is a lie. I feel furious about the fact that this company shows a misleading information about me, long after I deleted my account.

Projects for 2019 and a challenge

It’s almost the end of 2018, so I updated my expectations post from a year ago, you may find it interesting.

Now, here is a list of projects which are almost done on paper and which deserve attention or reserve some surprises for 2019. Then a challenge for you, dear creative reader.

  • I mentioned Hydrogen previously. This is a project to build a realistic hydrogen atom purely in software. This means that I need a theory (a lambda calculus like) for state spaces, then for quantum mechanics and finally for a hydrogen atom.
  • Space is of special interest (and needed to build hydrogen), a lambda calculus for space is proposed in the em project. Now I am particularly fascinated by numbers.
  • The needs project is a bridge towards chemlambda.  It’s entirely written, in pieces, it is about permutation automata. Only the main routine is public.
  • And what would life be without luck, aka computable probabilities? This is the least advanced project, for the moment it covers some parts of classical mechanics, but it is largely feasible and a pleasure to play with it in the year to come.


I have a strong feeling that these projects look very weird to you, so I have a proposal and a challenge. The proposal for you is to ask for details. I am willing to give as much as (or perhaps more than) you need.

The challenge is the following.  As you know my banner is “can do anything”.  So let’s test it:

  • propose a subject of research where you are stuck. Or better, you want to change the world (in a good way).
  • I’ll do something about it as quick as possible, if you get me interested.
  • Then I’ll ask for means. And for fairness.
  • Then we’ll do it to the best of our capacities.

Well, happy 2019, soon!


Open Science is rwx science

Preamble: this is a short text on Open Science, written a while ago,  which I now put it here. It is taken from this place at The link (not the content) appeared here at the Chemlambda for the people post. I can’t find other traces, except the empty github repository “creat”,  described as “framework for research output as a living creature“.


I am a big fan of Open Science. For me, a good piece of research is one which I can Read Write eXecute.

Researchers use articles to communicate. Articles are not eXecutable. I can either Read others’ articles or Write mine. I have to trust an editor who tells me that somebody else, whom I don’t know, read the article and made a peer-review.

No. Articles are stories told by researchers about how they did the work. And since the micromanagement era, they are even less: fungible units to be used in funding applications, by the number or by the keyword.

This is so strange. I’m a mathematician and you probably know that mathematics is the most economical way to explain something clearly. Take a 10 pages research article. It contains the intensive work of many months. Now, compress the article further more by the following ridiculous algorithm: throw away everything but the first several bits. Keep only the title, the name of the journal, keywords, maybe the Abstract. That’s not science communication, that’s massive misuse of brain material.

So I’m an Open Science fan, what should I do instead of writing articles? Maybe I should push my article in public and wait after that for somebody to review it. That’s called Open Access and it’s very good for the readers. So what? the article is still only Readable or Writable, pick only one option, otherwise it’s bad practice. What about my time? It looks that I have to wait and wait for all the bosses, managers, politicians and my fellow researchers to switch to OA first.

It’s actually much easier to do Open Science, remember! something that you can Read, Write and eXecute. As an author, you don’t have to wait for the whole society to leave the old ways and to embrace the new ones. You can just push what you did: stories, programs, data, everything. Any reader can pull the content and validate it, independently. EXecute what you pushed, Read your research story and Write derivative works.

I tried this! Want to know how to build a molecular computer which is indiscernible from how we are made? Use this playground called chemlambda. It’s a made up, simple chemistry. It works like the real chemistry does, that is locally, randomly, without any externally imposed control. My bet is that chemlambda can be done in real life. Now, or in a few years.

I use everything available to turn this project into Open Science. You name it: old form articles, html and javascript articles, research blog, Github repository, Figshare data repository, Google collection [update: deleted], this 🙂

Funny animations obtained from simulations. Those simulations can be run on your computer, so you can validate my research. Here’s what chemlambda looks like.

[Here come some examples and animations. ]


During this project I realized that it went beyond a Read Write Execute thing. What I did was to design many interesting molecules. They work by themselves, without any external control. Each molecule is like a theorem and the chemical evolution is the proof of the theorem, done by a blind, random, stupid, universal algorithm.

Therefore my Open Science attempt was to create molecules, some of them exhibiting a metabolism, some of them alive. Maybe this is the future of Open Science. To create a living organism which embodies in its metabolism the programs and research data. It’s valid if it lives, grow, reproduces, even die. Let it cross breed with other living creatures. In time the natural selection will do marvels. Life is not different than Science. Science is not different than life.

Authors: hodl your copyright or be filtered

For me this is the only sane reaction to the EU Copyright Directive. The only thing to do is to keep your copyright. Never give it to another. You can give non-exclusive rights of dissemination, but not the copyright of your work.

So: if you care about your piece of work then hodl copyright, if you don’t care about it (produced it to satisfy a job demand, for example) then proceed as usual, is trash anyway.

For my previous comments see this and this.

If you have other ideas then share them.


The second Statebox Summit – Category Theory Camp uses my animation

with attribution.

UPDATE: the post was initially written as a reaction to the fact that the Open Science project chemlambda needs attribution when some product related to it is used (in this case an animation obtained from a dodecahedron molecule which produces 4 copies; it works because it is a Petersen graph). As it can be seen in the comments everything was fixed with great speed, thank you Jelle. Here’s the new page look

Wishing the best to the participants, I’d like to learn more about Holochain in particular.

The rest of the post follows. It may be nice because it made me think about two unrelated little facts: (1) I was noticed before about the resemblance between chemlambda molecules and the “vajra chains” (2) well, I CHING hexagrams structure and rewrites are close to the two families of chemlambda rewrites, especially as seen in the “genes” shadow of a molecule. So putting these two things together, stimulated to find an even more halucinatory application of chemlambda, I arrived to algorithmic divination. Interested? Write to me!


I hope they’ll fix this, the animation is taken probably from the slides I prepared for TED Chemlambda for the people (html+js).

Here’s a gif I made from what I see today Saturday 20:20 Bucharest time.


Otherwise I’m interested in the subject and open to discussions, if any which is not category theory PR, but of substance.

UPDATE: second thoughts

  • the halucinatory power of chemlambda manifests again 🙂
  • my face is good enough for a TED conference (source), now my animation is good for a CT conference, but not my charming personality and ideas
  • here is a very lucrative idea, contact me if you like it,  chemlambda OS research could be financed from that: I was notified about the resemblance between chemlambda molecules and the vajra chains of awareness, therefore what about making an app which would use chemlambda as a divination tool? Better than a horoscope, if well made, huge market. I can design some molecules and the algorithm for divination.

A stochastic version for hamiltonian inclusions with convex dissipation

Appeared as arXiv:180710480  (it was previously available as (draft) )

A stochastic version and a Liouville theorem for hamiltonian inclusions with convex dissipation

Abstract: The statistical counterpart of the formalism of hamiltonian systems with convex dissipation arXiv:0810.1419  arXiv:1408.3102 is a completely open subject. Here are described a stochastic version of the SBEN principle and a Liouville type theorem which uses a minimal dissipation cost functional.

just in time for the anniversary of my son Matei 🙂
