Quantum physicists Chiara Marletto and Vlatko Vedral talk about a novel unification between information theory and thermodynamics using 'Constructor Theory,' their recent experiment that tested, and corroborated, the constructor theoretic notion of irreversibility, and the boundary between life and non-life with Logan Chipkin.

![Neuroscientists test the idea that what we see when we perceive the world is an internal projection.
You are walking across a vast grass field on a misty morning when you suddenly spot a lake in the distance. As you get closer, you notice a lone duck swimming peacefully across it. But this image doesnt last. After walking another ten yards, you realise your mistake—it isnt a duck but a plastic bottle. Your perfectly smooth conscious image changes rather abruptly, flipping seamlessly from duck to bottle.
Conscious visual perception—what we are conscious of seeing—is typically explained by light bouncing off the various items around us and hitting our eyes retina. The signal then travels to the back of our brain for visual processing and is fed forward through more complex areas until the brain can generate a perfectly coherent conscious image. A similar process takes place for other types of perception. But this raises a puzzle: if true, why is our conscious perception seemingly so perfect, lacking gaps even while we struggle to discern something?
