    Coincidences. Noise. Systems. Predictions.

    When we predict future climate, it is important to understand the climate of the past. We do. Mostly. Some details are still debatable. An example of that are the periodicities of ice ages – that is, how ice ages come and go. This is described in a theory developed by amongst others the astronomer Milankovitch […]

  • Afraid.

    Afraid.

    Afraid? Presence of a stranger can have a calming effect. (1) We are never alone. But we are afraid when we believe we are alone. Look around you. Talk to the forest. Shhhhhh… You do not need any reassurance. It is the forest that is terrified! Tell the cosmos not to be afraid. You are […]

  • Being afraid of Nothing…

    Being afraid of Nothing…

    Scientists have created the fastest spinning object ever made, taking them a big step closer to being able to measure the mysterious quantum forces at play inside ‘nothingness’. The record-breaking object will pave the way for scientists to detect unfathomably small amounts of drag caused by the ‘friction’ within a vacuum. The science of nothingness […]

    Classical physics. QM. Intuitionism.

    In classical physics, it is accepted that everything has already been determined since the Big Bang. To explore the future of our cosmos, physicists employ the language of classical mathematics and represent the universe’s initial conditions conditions by real numbers. “These numbers are characterized by an infinite number of decimals that follow the dot,” says […]

    Tractionless movement.

    Understanding how cells move autonomously is a fundamental question for both biologists and physicists. Experiments on cell motility are commonly done by looking at the motion of a cell on a glass slide under a microscope.  In those conditions, cells are observed to “crawl” on the surface. Crawling is well understood: cells attach themselves to […]
