I recently read the book “The Circle” by Dave Eggers. It’s about a Facebook-Twitter-like Internet company called “The Circle” that wants to create complete transparency and networking – privacy, unfortunately, falls by the wayside. The quote above is by one of the Circle bosses and he uses it to justify his ubiquitous surveillance. I am sure that we would all answer this question affirmatively. We behave differently under surveillance than when we are alone. So does that mean that pure observation influences our behaviour?
Polar ice, the moon, the quantum world – what do these places have in common? There is no Wi-Fi? Possibly. It’s uncomfortable? Probably. They are uninhabited? Not at all! All these places have (allegedly) already been seen by a certain living being. Sometimes by choice, sometimes by design, sometimes by accident. What kind of creature is it that hangs around in such exotic, hostile places? It is small, chubby and it’s name: Tardigrade! In 2014, tardigrades were found in the Arctic that had been “hibernating” for over 30 years. Since a crash landing of an Israeli space probe in 2019, a few tardigrades have been lying on the moon. And according to a group of researchers, tardigrades have now also made the leap into the quantum world! But is that really true?
Santa’s gift tour is a headache for children every year: How does he manage to visit every child in the world in a single night? But Santa’s travel speed is not the only problem. I wonder: how does he know if the child whose chimney, balcony or front door he is standing in front of has been naughty or nice? Does he carry around the naughty-nice-list in paper form? Is he in radio contact with the North Pole? Or does he have a completely different method? We will ask the question: Is communication faster than the speed of light possible?
Schrödinger’s cat is considered the mascot and heraldic animal of quantum physics. Ever since Big Bang Theory, at the latest, it has also been tapping into the living rooms of non-physicists. But as popular as she is, most people don’t really understand what she’s all about. Since Christmas is just around the corner and I strictly reject animal testing, I decided to do it a little differently: Let’s help Santa Claus and find out if a child is good or bad.
