A story on hot food and cold drinks, country boys and city slickers, as well as some capital hipster fun. Oh, and there is science, of course.Read More It’s a wrap!
(with a nod to Carl Sagan) Why are people so afraid of science? Or are they? As a scientist, or, in fact, as a curious human being, I cannot but notice that science is treated differently from other aspects of life. To give just one example, a car mechanic can point towards his experience and […]Read More Science angst: On hunter-gatherers and science
Sometimes we toss comments, more than discussing, about leaving Earth for another planet. Well – That would be a kind of a journey. Freja, a space engineer student at Luleå tekniska universitet, wrote an essay that might give you some perspective on a journey to a planet, orbiting another star. In-betweeners – by Freja Andrea Dyrbye […]Read More In-betweeners
In some sense, this was the shortest visit to a museum ever. I had half-an-hour for this bounty of different instruments from all epochs of science since the 16th century, concentrated in a cellar somewhere on the premises of the University of Padova, in Galileo Galilei’s town. Thankfully, I had a wonderful guide. In addition, […]Read More A visit to Galileo’s cellar
In science you should never say no. To anything. Period. Until it is proven wrong. Then you shout No! to the world. Technology development, now, may be a rather different story. Just take this. What would provoke NASA to give such an un-equivolent message about a particular mainstay of Sci-Fi-literature, the warp drive. One should […]Read More Warping drives
One of my favourite games as a youngster was to skip stones on water. I was really bad at it – and still I became a physicist, a rocket scientist even. So, why does a stone skip on the water? You can find answers here at Quora. It is basically about vectors and where they […]Read More Skipping stones like a boss
I asked a stupid question on Google+. I rather often do, so that is not unusual. At about the same time of that post, I called mixing up the terms scientists, researchers and engineers like assigning grey colour to a blue sky, something more than simply not getting categorizations straight, on this very blog. I […]Read More Brilliant minds
There are many texts out there which discuss the reflection of light from surfaces. A good example would be found here. Now, as well as these articles are written, I do have a question. How come that water can reflect light? Isn’t it supposed to be transparent? Mirrors work in such a way that electrons […]Read More Why would a lake reflect a mountain?
