[:es]One Lab’s Quest to Build Space-Time Out of Quantum Particles[:]

[:es]For over two decades, physicists have pondered how the fabric of space-time may emerge from some kind of quantum entanglement. In Monika Schleier-Smith’s lab at Stanford University, the thought experiment […]

[:es]The Brain Doesn’t Think the Way You Think It Does[:]

[:es]Familiar categories of mental functions such as perception, memory and attention reflect our experience of ourselves, but they are misleading about how the brain works. More revealing approaches are emerging.[:]
