  • The 105th ICREA Colloquium 'Gravitational waves from the 5th dimension'


    Speaker: ICREA Research Professor David Mateos, from the Universitat de Barcelona (UB)


    When: 28th of March 2023, 18:00h


    Where: Zoom & Auditorium FCRI, Passeig de Lluís Companys, 23, 08010 Barcelona




    Our understanding of the Universe at the most fundamental level is based on two seemingly radically different theories. Einstein’s General Relativity describes the gravitational force that governs physical processes on the largest possible scales. The revolutionary experimental discovery of gravitational waves, little ripples on the geometry of spaces and time, is the latest confirmation of Einstein’s theory. The other three forces in Nature, the electromagnetic, the strong and the weak force, are unified in a single framework known as Quantum Field Theory, which describes subatomic processes. The most important discovery in theoretical physics in the last 25 years is an exact equivalence between Quantum Field Theory in 1 time and 3 spatial dimensions, as in our Universe, and General Relativity… in one dimension higher! I will describe the basis of this correspondence, known as Holography, as well as applications to particle physics, cosmology and gravitational waves.


    The ICREA colloquia are a great way to learn about remote fields of research from our best experts. They are open to all ICREAs and their guests.

  • Workshop ‘Credit, diversity, and research quality in science’


    Prof. Joshua Shepherd, who will become an ICREA Research Professor in May 2023, will be hosting the workshop entitled ‘Credit, diversity, and research quality in science’.


    This workshop will address credit assignment in science – who gets credit for which discoveries and achievements – and how credit assignment impacts and is impacted by [a] collaboration, [b] assessments of research quality, and [c] issues of diversity, equality, and inclusion.

    As AI systems start being deployed in a large number of everyday contexts, it is particularly important to study the transparency and trustfulness of these systems from different perspectives.


    In the first part of our joint talk, we will consider whether AI systems can have disadvantageous consequences for people based on the social group to which they belong, i.e., whether AI can engage in indirect discrimination, specifically statistical group discrimination. We will consider various examples of this phenomenon, which seems quite pervasive and particularly affects high-risk applications of AI, such as those related to housing, employment, and the administration of justice.

    In the second part, we will consider to what extent large AI systems trained to "speak English" by being exposed to large amounts of text are really understanding natural language like humans do, and to what extent they have instead developed an alternative communication code that is only superficially resembling English. We will discuss some surprising results that suggest that the second hypothesis is correct, and the implications that this might have in terms of the usability and safety of these systems.


    The ICREA colloquia are a great way to learn about remote fields of research from our best experts. We usually have two speakers, who offer their opinions on the same subject from different angles. They are open to all ICREAs and their guests.
