Über kleine Teilchen und kleine Physiker:innen
Quanta are sensitive little beings. Under the influence of peer pressure, they behave completely differently when someone is watching. Quantum mechanical measurements behave completely differently from classical measurements, i.e. the ones we know from everyday life. That’s what we’re going to talk about today: The pitfalls and subtleties of quantum mechanical measurement – and why they are so fascinating!
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?
