Dear colleagues and friends in symmetry studies:

Let us hope that in this year, with the process of normalizing the international contacts and transport links of the scientific and cultural community, our research, popularization and publication activity in the field of symmetry and its applications will continue to develop and strengthen.

Best wishes for a healthy, peaceful and prosperous Happy New 2023 Year!

The International Symmetry Association (ISA) announces new date for proposals for organizing and hosting the next Symmetry Festival (to be held in 2024)

The application must come with a well-thought out and clear scientific program. The costs of the conference, accommodation and trips must be set out well in advance. If the conference is to have a ‘hybrid’ element, so that it can be delivered both online and attended in person, the online platform used needs to be readily accessible and simple to use. The organizing committee and ISA must open a website where new items can be communicated. First circulars and calls for papers/abstracts should be well in advance of the Symmetry Festival. Deadline for applications: January 31, 2023.

Open position for editor of the journal of Symmetrion: Symmetry: Culture and Science (SCS)

Tasks to be performed by the editor of Symmetry: Culture and Science (SCS):

  • collect and manage submitted papers;
  • invite potential authors (potential author should be selected either from the mailing list of the ISA, or by contacting new persons interested in any aspect of symmetry studies, based on the editor’s private search among publications in other journals, books, mainly in the internet);
  • make the submitted papers peer reviewed;
  • identify the most appropriate reviewers;
  • communicate with the reviewers;
  • decide on the acceptance or rejection of the papers;
  • manage the post-review corrections of the paper, communicate with the authors until the paper achieves its expected, final form;
  • take care of whether the paper is formatted in a publishable form and its English is acceptable in a prestigious journal;
  • submit the camera ready issue to the publisher, in due deadline before the end of each quarter of the year.

Expected abilities of a prospective editor of SCS:

  • affinity to all the sciences, humanities and arts;
  • practice in editing;
  • easy communication to any representative of the sciences, humanities and arts;
  • being not ashamed to contact as a peer, when needed, anybody unknown (by her/him) scholar, either as author or reviewer, even in those disciplines where she/he is not very familiar;
  • commitment to have, at least, a short look at the earlier published works of a scholar before contacting her/him;
  • commitment to avoid bulk mail communication (readiness to include at least a few personal words in the letters to everybody that may convince the addressee about her/his importance for the journal; this is a testimony that the editor knows her/his works);
  • at least medium (or higher) level command of English;
  • commitment to accept and keep the established traditions at the journal;
  • keep deadlines;
  • commitment to different types of symmetry, as an interdisciplinary field of studies;
  • commitment to follow an editorial policy that does not jeopardize the (financial) sustainability of the journal;
  • commitment to try increasing the number of citations received to the published papers;
  • commitment to manage the increase of the journal’s impact factor.

Dear colleagues and friends in symmetry studies and applications

In the last two years one can hardly try to plan something for the near future. I thank all in person and online participants in the Symmetry Festival 2021, which was held in Sofia. We are looking forward to the next Symmetry Meeting, which will be probably held in Pécs, Hungary, in 2023 after the official approval by the ISA Board. I hope most of us shall be able to attend in person by then. The next year is declared by UNESCO as an International Year of Basic Sciences for Sustainable Development (https://www.iybssd2022.org/en/home/) with a lot of scientific and technical partners and supporters. Symmetry is a universal principle, as well as a way of thinking and a way of life! It has no borders for sciences, arts and innovations!

I take the chance to wish you all a healthy and prosperous Happy New 2022 Year!

Steven Weinberg (3 May 1933, New York City – 23 July 2021, Austin, Texas)


Steven Weinberg (3 May 1933, New York City – 23 July 2021, Austin, Texas)

Nobel laureate (1979) Steven Weinberg was Honorary Member of the International Symmetry Association (2009-). Besides the Nobel prize, he won many other prizes and distinctions. His discoveries deepened understanding of the basic forces at play in the universe.

The work for which Dr Weinberg was awarded the Nobel had a transformative impact on physics to understand and explain what happens in the subatomic world. He discovered that two of the universe’s forces are really the same and helped to lay the foundation for the development of the Standard Model, a theory that classifies all known elementary particles in the universe, making it one of the most important breakthroughs in physics in the 20th century.

Though he had the respect, almost awe, of his colleagues for his scientific abilities and insights, he also possessed a rare ability among scientists to communicate and explain abstruse scientific ideas to the public. He was a sought-after speaker, and he wrote several books in the fields of the foundations of physics and cosmology. He read a keynote lecture at the 2009 Symmetry Festival held in Budapest with the title “Accidental Symmetry”. An edited version of his paper was published in Symmetry: Culture and Science (Vol. 23, No. 1, pp. 5-16).

There are four known forces in the universe: gravity; electromagnetism; the strong force, which binds the nuclei of atoms together; and the weak force, which causes radioactive decay. The first two forces have been known for centuries, but the other two were discovered only in the 20th century. Physicists struggled long to find a theory that would account for all the forces. Though there were significant discoveries, a unified theory or model remained elusive.

He proposed that, at very high energy levels, the electromagnetic and weak forces should be one and the same. It was a step on the path to the unified theory that physicists had been searching for. Dr Weinberg published his findings in 1967 in a groundbreaking paper, “A Model of Leptons,” in the journal Physical Review Letters. The article is one of the most-cited research papers in history.

Among many groundbreaking theoretical discoveries, he developed the theory of ‘symmetry breaking’. (Not to be confused with the notion of the violation of symmetry.) Introducing the idea of a process called by him ‘spontaneous symmetry breaking’, he gave a model to explain the mass difference of the bosons that mediate between the agents of the electroweak interaction. Weinberg’s model, known as the electroweak unification theory, had the same symmetry structure as that proposed by Glashow in 1961.

Then, the electroweak theory was made consistent with a theory of the strong interactions between quarks, in one overarching theory, based on a unification of the symmetry groups characterising the individual physical interaction types. The model developed by him (and independently by A. Salam) was revolutionary, not only for proposing the unification of the electromagnetic and weak forces but also for creating a classification system of masses and charges for all fundamental particles, thereby forming the basis of the celebrated Standard Model of physics, which includes all the forces except gravity.

S. Weinberg, A. Salam and Sh. L. Glashow, an old high school classmate of Dr Weinberg’s who had resolved a critical problem with the Weinberg-Salam model, were jointly awarded the 1979 Nobel Prize “for their contributions to the theory of the unified weak and electromagnetic interaction between elementary particles” based on spontaneous symmetry breaking. His contribution to the development of the theory of physical symmetries raised him among the greatest physicists of the 20th century.

He never retired, he taught until the spring of this year. During his decades at the University of Texas at Austin he tutored many students, eight of them became full professors and five assistant professors at his university.
