MARIUS BULIGA

     
     

     
RIGHT NOW: working on deferred groups (aka groups are all the same), emergent algebra, recursive(?) statistics, hamiltonians with dissipation, thermodynamics, damage. (Names may change.)
     
See down the page for past/present published work and research subjects.
     

     
I have a mostly research wordpress.com blog/open notebook with more than 600 articles.
     

     
CLAIM: It is possible to build molecular computers, in a new way. For the experts: I believe there exists an encoding of chemlambda molecules, in such a way that the chemlambda model can be realized via real chemistry. Public resources are Chemlambda strings and the paired needs repository.
     

     
ABOUT ME: I practice Open Science. Really open.
  • I explain why Open Science is something you should think about in this interview (archived version) where I'm kindly presented as "a researcher who started doing "open science" even before the term was actually coined".
  • As an experiment, between 2015-2016 I tried to use social media for Open Science. It resulted in very high public exposure because it is both visually appealing and based on rigorous research. The chemlambda collection (direct access list of posts) contains more than 350 animations obtained from simulations using the Chemlambda repository, which can be independently validated by using the Library of chemlambda molecules. It was featured by Google and viewed more than 50 million times. The experiment was successful, I hope to replicate it at a large scale.

     
VALIDATION vs PEER-REVIEW: There is no rational doubt that it is technically possible to replace peer-review, which is a social form of validation, by a more rigorous version: give all to the reader, proofs, programs, data and let the reader form an opinion based on that. As an example is this experimental GitHub article which "runs in the browser" and comes with all means for validation: Molecular computers. That is why I believe that GitHub, as a (temporary) example, already answered, in principle, to the question: how will we collaborate, communicate, do research in the Net era?
     

     
I signed the San Francisco Declaration on Research Assessment (DORA), as well as The Cost of Knowledge.
     
If you care about which licence to use for your work, then CC BY 4.0 International is a good choice, because it forbids downstream restrictions on the dissemination of your work. Any licence which does the same is as good as this one. Truth is that licences become less important than DRM, which controls the ways the reader has access to the licensed work.
     

     
MORE: I have a Habilitation à diriger des recherches en Sciences Mathématiques (download the thesis), (diploma scan), USTL (Lille I), France (2007). See also my Scholar profile.
