Alexandra Delbot discusses Young's double-slit experiment with physicists Christophe Salomon and Serge Haroche. They trace its role in establishing interference and examine how electron experiments, measurement and quantum theory changed the interpretation of the experiment and of wave-particle duality.

Jérémie Naudé and Albert Moukheiber join Alexandra Delbot to examine popular misconceptions about the brain, including claims about dopamine detoxes. They discuss what neuroscience experiments establish about dopamine and reward prediction, and how simplified biological narratives can distort research and public understanding.

Astrophysicist Benoît Famaey and theoretical physicist Francesca Calore discuss the evidence motivating dark matter and the challenges of identifying its nature. With Alexandra Delbot, they examine proposed particle candidates, possible detection signals and why a promising observation requires careful scrutiny before being treated as a discovery.

Alexia Auffèves and Pascale Senellart-Mardon explain quantum energetics and the energy costs of quantum technologies. Alexandra Delbot asks how researchers can measure exchanges of energy, entropy and information, develop useful efficiency metrics, and incorporate energy constraints while quantum computers are still being designed.

Mathematicians Sylvia Serfaty and Amaury Hayat discuss AI-assisted mathematical research with Alexandra Delbot. The conversation examines recent claims of difficult problem solving, how researchers assess and understand machine-generated proofs, and the implications for publication, mathematical practice and the responsibilities raised by the Leiden declaration.
