The Final Frontier: Quantum Physics in Space

Within the last two decades, quantum physicists have been busy proposing experiments that could be done in space. At long last, their efforts seem to produce results. Lately, two more results have been published, both groups are rather well-known to qutools: Wheeler’s delayed choice experiment has been performed by Paolo […]

Armadillos on the 13th floor

Electrons in van der Waals materials use shortcuts to travel fast People just love protons. On the other hand side: If they talk about electrons, they always tend to emphasize the negative aspects. Though there are some advantages being an electron, too. As scientists at the KU’s Ultrafast Laser Lab […]

Uncertainty is a game. Play it.

How did James Bond win at Casino Royale? Why do I always lose at Monopoly? Is it any use to join the imperial army in Skyrim? These are the topics of game theory. Or so you might think, because that’s just plainly wrong. „Game theory“ is a rather young and […]

Why is there „something“?

Maybe we are a little step further to explain why there is „something“ rather than „nothing“. Because the Standard model of physics – which worked quite well to describe the universe so far – tells us that there should be: (dramatic pause) Nothing at all. First there was just plain […]

Sensation: Physicists manipulate nothing!

It’s exactly as some strange esoteric websites have told you for decades: Quantum physicists manipulate nothing. This is the case NOT because there are no quantum objects, but because there is no nothing. Literally. We cannot produce a perfect vacuum. And that’s not because our pumps or our containers aren’t strong […]

The very cool drum

Quantum physics tends to look like “magic”. This is one reason why it’s so quool. Cool, actually. Very cool. Very, very cool. “As-cool-as-it-can-get”-cool. Like in “absolute zero”. Which is really cool, because enthalpy and entropy reaches zero. No temperature at all, meaning no energy, no movement. We know about this […]

From Delft’s quantum lab

This little video was made by Hannes Bernien from the Delft University of Technology. If you were curious what the workplace of a quantum physicist looks like: Here you can have a glimpse. So much up front: It’s underground, it’s dark and it makes no sense to normal human beings. […]

Beaming can kill you!

  An nerd fight rages over at YouTube. The clever explain-it-alls at C.P. Grey started it. In a charming video they explain, why teleportation as seen on television – in all Star Trek franchises, to be exact – can not work as advertised. Discussed not only on a scientific base, […]

Spooky Action At A Distance

In his book “Spooky Action at a distance” George Musser does a good job in explaining quantum physics. And he continues to do so on his website spookyactionbook.com In his latest article he explains “How Are Entangled Particles Created“. And this video helps a lot in doing so: And don’t […]
