- October 2000:
...Those who consult this site regularly, and there are some, are doubtless waiting for novelties of all kinds. For several months I have been very busy with various scientific projects. This has even prevented me from advancing the comic strip on groups, which some are waiting for. On this subject, who would have a title for such a comic strip?
...As usual, when things have taken shape, I will report on them in the site. But, as a preview, a few images. Those who have read my books know that at the beginning of the nineties a certain Frédéric (who preferred to remain anonymous) had carried out computer simulations in which the spiral structure of a galaxy was attributed to the interaction between our universe and its twin, between a galaxy and its "conjugate" image, located in the twin universe. Read on this subject the article recorded in the site. The work in question dated from 1992. Subsequently, Fred having left the DAISY laboratory, in Hamburg, where he had managed to divert 10% of the computing power of the computer managing the particle accelerator to carry out these simulations, and no longer having adequate means in his new lab, the work had been stopped. They have just resumed a few months ago. I have two very active and very efficient "students", Pierre Miret and Pierre Davous, who are in Paris. The first is 68 years old and the second 74 (I am 63 myself). It happens, as Fred had pointed out to me, that the power of certain micros accessible to the general public (essentially ...Macs) means that calculations which could only be done eight years ago on large systems are now within the reach of much more modest machines. When they had made contact with me, at the end of 99, Miret and Davous had simulated the structure of M51, of the galaxy of the hunting dogs, using 5000 point-masses for the galaxy and 200 for the perturbing companion. Everything had worked very well and these two "amateurs" had reproduced the work which was considered cutting-edge only fifteen years ago. Encouraged by this result, they had therefore made contact with six astrophysicists, offering their services. None replied. I was the seventh and I immediately hooked them up on the problems that we had tackled, Fred and I, eight years earlier. Thanks to Davous's programming talent (in C) and Miret's tenacity, here are the first images coming out. They are frankly likeable.
...Moreover we have been able to reconstruct a sequence which shows the birth of a galaxy. A first. But I will leave you the surprise. There, it is getting a little late.
- In the maths department: how to transform a left Boy surface and right Boy surface, passing through the Roman Steiner surface.
- On the homepage: the central model of the Turning Inside Out of the Cube
- See also the monohedron: a polyhedron which possesses only a single face and a single edge.
- Although these are not new works (I abandoned MHD in 87), the reader will find elements that may interest him in this new section. I had long intended to talk about this field, which I know well, on my site.
- Our current work is focused on replacing the black hole model, tainted with grave mathematical inconsistencies, with that of the hyperspatial transfer of matter from a destabilized neutron star, via a "hypertoric bridge" putting two universes, ours and its "twin", in communication, a model in the draft stage. The reader will nevertheless find a critical analysis of the black hole model. See the introduction in French of the questionable black hole paper.
- Also go and see the new axiomatization of groups, due to Souriau.
- Publishing in peer-reviewed journals is painful. However, latest publication:
