I am afraid any such seminars are pointless as long as one continues to combine the sane (Newtonian) concept of time used in quantum mechanics and the insane concept of time offered by special relativity:

Joao Magueijo, Faster Than the Speed of Light, p. 250: "Lee [Smolin] and I discussed these paradoxes at great length for many months, starting in January 2001. We would meet in cafés in South Kensington or Holland Park to mull over the problem. THE ROOT OF ALL THE EVIL WAS CLEARLY SPECIAL RELATIVITY. All these paradoxes resulted from well known effects such as length contraction, time dilation, or E=mc^2, all basic predictions of special relativity. And all denied the possibility of establishing a well-defined border, common to all observers, capable of containing new quantum gravitational effects."

Frank Wilczek: "Einstein's special theory of relativity calls for radical renovation of common-sense ideas about time. Different observers, moving at constant velocity relative to one another, require different notions of time, since their clocks run differently. Yet each such observer can use his "time" to describe what he sees, and every description will give valid results, using the same laws of physics. In short: According to special relativity, there are many quite different but equally valid ways of assigning times to events. Einstein himself understood the importance of breaking free from the idea that there is an objective, universal "now." Yet, paradoxically, today's standard formulation of quantum mechanics makes heavy use of that discredited "now." Playing with paradoxes is part of a theoretical physicist's vocation, as well as high-class recreation. Let's play with this one. (...) As we've seen, if a and b are space-like separated, then either can come before the other, according to different moving observers. So it is natural to ask: If a third event, c, is space-like separated with respect to both a and b, can all possible time-orderings, or "chronologies," of a, b, c be achieved? The answer, perhaps surprisingly, is No. We can see why in Figures 5 and 6. Right-moving observers, who use up-sloping lines of constant time, similar to the lines of constant t2 in Figure 2, will see b come before both a and c (Figure 5). But c may come either after or before a, depending on how steep the slope is. Similarly, according to left-moving observers (Figure 6), a will always come before b and c, but the order of b and c varies. The bottom line: c never comes first, but other than that all time-orderings are possible. These exercises in special relativity are entertaining in themselves, but there are also serious issues in play. They arise when we combine special relativity with quantum mechanics."

Nottingham Centre of Gravity Inaugural Colloquia

As part of its launch, the Nottingham Centre of Gravity (NCoG) is organising a series of Inaugural Colloquia. The NCoG brings together Nottingham's internationally leading expertise in gravitational physics in the School of Mathematical Sciences and the School of Physics and Astronomy and plans to expand it into new areas. It will be built on six overlapping pillars of gravitational research: fundamental physics, mathematics, cosmology, relativistic astrophysics, experiment, and data & modeling. The six Inaugural Colloquia will span these fields.

The Colloquia will be broadcast via Zoom and all are welcome to attend. Please feel free to share this with friends and colleagues.

The schedule of talks is given below, with the first talk by Cumrun Vafa (Harvard) taking place on October 6, 2021. You can access all the talks through the following link:

Title: String Landscape and the Swampland

Abstract: String theory landscape of vacua point to new consistency conditions that a quantum gravitational system must satisfy. There are only a small number of quantum field theories that satisfy these conditions and all the rest belong to the `Swampland' which cannot be consistently coupled to gravity. In this talk I review some of these conditions and their implications for cosmology and particle physics.

The Many-Worlds Interpretation of Quantum Mechanics

Current Status and Relation to Other Interpretations

Center for Quantum Science and Technology

Tel-Aviv University, 18-24 October 2022

The MWI solves the measurement problem, avoids action at a distance and indeterminism and does not contradict empirical evidence. Why, then, it is not in the consensus? The workshop will aim to promote the ongoing debate on the foundations of quantum mechanics by dealing with the major open questions regarding the MWI and its alternatives.

Dear Colleagues,

It is a pleasure to advertise the workshop “New Strategies for Extracting Cosmology From Future Galaxy Surveys”, to be held in Sexten, Italy from 3rd to 7th July.

This workshop will be focused on a broad range of new and established methods for the analysis of galaxy clustering, with a focus on forthcoming spectroscopic surveys, such as Euclid and DESI. The goal is to foster discussion and sharing of expertise to develop the necessary techniques and tackle expected and unexpected challenges for the cosmological analysis of these surveys. We would like to particularly discuss what are the steps and challenges that need to be overcome for new proposed methods (such as voids, marked and skewed correlation functions, topological features, one-point statistics, forward models, …) to develop a full analysis pipeline and obtain trustable cosmology constraints.

The workshop has a limited number of participants, so attendance is moderated through a pre-registration on https://indico.sissa.it/event/93/ with deadline 3rd March. The final list of participants will be made right after.

PhD students and junior postdocs are especially encouraged to apply.

A few infos about the workshop:

The Sexten Center for Astrophysics will be administrating the workshop, which is held at the primary school in Sexten, Italy, a stunning location on the Italian Alps.
We expect a maximum amount of 30-35 participants
A fee of 230 euro for seniors and 200 for students is due to the Sexten center upon acceptance of your pre-registration.
Info on accommodation and transport is on the Sexten website, here: https://www.sexten-cfa.eu/event/newstra23/. Neither accommodation nor transport are included in the fee.

For any further scientific or logistic questions do not hesitate to ask us!

The 20th International Conference on Quantum Physics and Logic (QPL

2023) will take place from 17 July to 21 July 2023 at the "Institut

Henri Poincaré" in Paris, France.

Quantum Physics and Logic is an annual conference that brings together

academic and industry researchers working on mathematical foundations of

quantum computation, quantum physics, and related areas. The main focus

is on the use of algebraic and categorical structures, formal languages,

type systems, semantic methods, as well as other mathematical and

computer scientific techniques applicable to the study of physical

systems, physical processes, and their composition. Work applying

quantum-inspired techniques and structures to other fields (such as

linguistics, artificial intelligence, and causality) is also welcome.
