# Welcome from the Chairs

Dear Colleagues,

This third edition of the International Conference on Symmetry, supported by Ben-Gurion University of the Negev and the MDPI journal Symmetry, sponsored by The Foundational Questions Institute (FQXi) and Center for Advanced Studies in Mathematics, will be held entirely online due to the COVID-19 pandemic, from 8 August to 13 August 2021.

We welcome interdisciplinary interaction between different fields of science and we intend to follow in the footsteps of Hermann Weyl, a man responsible for important progress in the field of symmetry in math and physics. He expressed great interest in symmetry in many additional fields of science, as explored in his eye opening book "Symmetry". As expressed by Weyl, symmetry is a fundamental phenomenon in nature and all sciences. This event, therefore, aims to promote the discussion and exchange of cutting edge knowledge and ideas of symmetry in a variety of subjects ranging from physics, chemistry, mathematics, and computer science, to biology.

Symmetry 2021 is a follow up to two very successful conferences, entitled "Symmetry 2017—The First International Conference on Symmetry", held in October 2017 in Barcelona, Spain, and "Symmetry 2019—The Second International Conference on Symmetry" in Benasque, Spain.

Registration is free for the submission and the live sessions.

Organizational questions and sponsorship opportunities can be directed to the Secretariat ([email protected]), and content questions should go to Prof. Eduardo Guendelman.

We look forward to having you join us at this exciting event.

Best regards

Eduardo Guendelman

Bio
Structural biology aims to understand the chemistry, interactions and basic biological functions governed by the three-dimensional structure of macromolecules. Knowledge of the 3-D structure of a protein can provide enormous basic scientific insight into the function of that protein, facilitating elucidation of its biochemical function and its interactions with other proteins, RNA, DNA, or membranes in the cell. X-ray crystallography and cryo-EM are the most prolific techniques for the structural analysis of proteins and protein complexes. Using X-ray crystallography and cryo-EM, we can now realize to the high-resolution range, up to atomic or even electronic details, enabling a full coverage understanding of macromolecules and their interactions. Current Projects 1. Structural studies of magnetosome associated proteins. Magnetotactic bacteria are a phylogenetically and morphologically diverse group of microorganisms that share an ability to create magnetosomes, biomineral organelles that sense geomagnetic fields and aid the bacteria to align themselves accordingly. The magnetosome organelle comprises aligned 30-50 nm iron oxide magnetite crystals, surrounded by a lipid bilayer membrane vesicle. There are several types of magnetosome-forming proteins all encoded by genes within a genomic island common to magnetotactic bacteria. These proteins include a set of incorporated membrane proteins that facilitate vesicle formation, vesicle localization and iron transport and a set of proteins that control magnetite formation and size. In my lab, we are tackling the structure-function relationships of these proteins. 2. Structural studies of cation diffusion facilitators (CDF), a special family of cation transporters. Cation diffusion facilitator (CDF) proteins constitute a group of heavy metal ion efflux transporters that participate in metal ion homeostasis and can be found in all domains of life. Members of the CDF protein family – functional in their dimeric form and comprising a transmembrane domain (TMD) and a cytoplasmic C-terminal domain (CTD) – exploi

Talk
Modern science is a Babel tower, the foundations of which are too often forgotten. Yet revolutions may occur when one takes seriously an essential question: Is it necessarily so?" Indeed a successful model is based on assumptions that are sufficient to explain existing data, but may not be necessary. That is the mathematical curse of experimental sciences, since one tends not to argue with success (or with what one has been taught) unless one is forced to. In 1960 Wigner (who in 1963 got the Nobel Prize in physics for the discovery and applications of fundamental symmetry principles") marvelled about the unreasonable effectiveness of mathematics in the natural sciences," referring mainly to physics. We shall briefly exemplify all this by first explaining how a posteriori relativity and quantum mechanics can be obtained from previously known theories using the mathematical theory of deformations, and by describing some main features of the (successful but probably incomplete) standard model of elementary particles, which arose from empirically guessed symmetries. Finally we indicate how, questioning its foundations, its symmetries could be obtained from those of relativity using deformations (including quantization), which poses hard mathematical problems and may eventually question more than half a century of particle physics. Complementing that approach by using the strings framework" is optional.

In construction of the conformal invariant Lagrangian we restrict ourselves to the so-called Quadratic Gravity. Then, in the Riemannian geometry there exist only one suitable combination, namely, the square of the Weyl tensor (completely traceless part of the curvature tensor). The corresponding left-hand side of the field equations, the Bach tensor, is linear in the Weyl tensor itself and its second covariant derivatives. But, for any homogeneous and isotropic cosmological space-time (i.e., Robertson-Walker metric with arbitrary scale factor) the Weyl tensor is identically aero. Thus, any cosmological metric is the vacuum solution of the Weyl gravity in the framework of the Riemannian geometry – no matter at all! In 1919 Hermann Weyl invented a new geometry, which is now called the Weyl geometry. He introduced some 1-form and incorporated it into the connections by demanding that the new covariant derivative of the metric tensor coefficient equals this 1-form times that very coefficient. Then, he showed that in order these new connections to be conformal invariant, the 1-form must behave under the conformal transformation of the metric as the gauge field. It was the great discovery! How about the cosmology in the Weyl geometry? We started with construction the Lagrangian for the single particle moving in the given gravitational field in the Weyl geometry and discovered that there may exist some new interaction, absent in the Riemannian geometry (and, particularly, in General Relativity). This is due to the existence of the yet another invariant, namely, the contraction of the 1-form with the particle four-velocity vector. We called it “the invariant B”. And we were able to incorporate it into the Lagrangian for the perfect fluid. The cosmological principle requires that the Weyl 1-form should have only one (temporal) non-vanishing component depending only on the time coordinate. Hence, it can be removed by a suitable conformal transformation (also depending only on time). In such a gauge all possible functions of our new invariant B are converted into the se
