Feynman’s Flower

The Sober Scientist. What an excrutiatingly weird concept to me. I am one myself, a scientist, I mean; and I know how much I have to force myself to not feel but think when it comes to science. Now, don’t get me wrong. I know where the image of the sober scientist comes from. It […]

A visit to Galileo’s cellar

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, […]

Warping drives

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 […]

Satellites in extraordinary orbits

Most of our satellites orbit the Earth – either in Low Earth Orbit, LEO, Medium Earth Orbit, or in Geostationary Orbit, GEO. The closer to the Earth a satellite is the shorter its period. So – What if the satellite is even further away than the geostationary satellites? Why would you place satellites that far […]

Prepare for surprises

Friday, November 13th, at a conference, Professor Hannu Koskinen, gave a speech about space as an almost infinite source of surprises. Being a part of the Rosetta team, he reminded the audience about comments on the first images showing the duck-shaped comet 67P/Chyryumov-Gerasimenko. The images of Pluto, captured by New Horizons, also were more surprising […]

Skipping stones like a boss

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 […]

To Venus with (love?)

Wherever you are early November you can see our closest planet, Venus, glimmering in the morning sky. Sometimes it appears as a morning star, sometimes like a bright evening star. Asteres planetai was the term used in ancient Greece before anyone got clues enough to build up a knowledge about these wandering stars. Now Venus is illuminating the […]

Brilliant minds

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 […]
