    Philosophy snapshot: Everything?

    Sitting for a quick coffee… Random thoughts. (Could anything get closer to the truth?) What is everything? If not something and nothing together?

    Limits of measurements… Limits of out self…

    The limits of classical measurements of mechanical motion have been pushed beyond expectations in recent years. But the sensitivity that we can achieve using purely conventional means is limited. For example, Heisenberg’s uncertainty principle in quantum mechanics implies the presence of “measurement backaction”: the exact knowledge of the location of a particle invariably destroys any…

    Light. Low light. Essence.

    It was a puzzle about birds. Migratory birds are known to rely on Earth’s magnetic field to help them navigate the globe. And it was suspected that a protein called cryptochrome, which is sensitive to blue light, was making it possible for birds to do this. Yet many of these animals are also known to…

    Passing through walls… Broken glass…

    Researchers have captured the most direct evidence to date of Klein tunneling, a quantum quirk that allows particles to tunnel through a barrier like it’s not even there. The result may enable engineers to design more uniform components for future quantum computers, quantum sensors and other devices. (1) We constantly see things. We sense things.…

    Self-cleaning surfaces and laboratories on a chip become even more efficient if we are able to control individual droplets. University of Groningen professor Patrick Onck, together with colleagues from Eindhoven University of Technology, have shown that this is possible by using a technique called mechanowetting. “We have come up with a way of transporting droplets…
