Cloud Chambers

At the moment I am working on my Master’s thesis. As this is taking up a lot of my resources, I fail at generating more content for this blog. Geophysics related writing goes into the thesis right now. However, I’ve written a short piece on visualizing radioaktive decay in a diffusion cloud chamber. It’s not […]

Do you know your seismic velocity?

In seismic data analysis a lot of work goes towards getting a good velocity model of the subsurface. We talk about the seismic velocity. However, this may lead to some serious misconceptions. One step in seismic processing is velocity analysis. We pick the velocity that adjusts our data for the best value. Usually this is […]

Scale matters

Snow in Cairo – First in 112 years

If you look at that picture you see the magnificent view of palms in the middle of snow. That is egypt and it’s snowing for the first time in 112 years. Of course didn’t take long for people to wonder if this has anything to do with climate change. Is it about climate change? […]

The state of science on climate change

Reading about climate change can be overwhelming. There are many questions asked and many implications for humans. The typhoon on the Philippines shows once again that Earth is changing. But the data alone isn’t very telling. No one I know has actually read those reports or has understood them very well. What does it mean […]

Fourier and Space – The FX Domain

Geophysics can get a little fancy. You have probably heard the geophysicists tend to hang around some mathematicians. When it comes to the topic of math most of my friends like to state: “I was good at math until they started mixing in the alphabet!” I hear ya. Complex numbers and pi and variables are […]

Mama Etna is back!

One big reason to go into geophysics is pretty obvious: Volcanoes! I got to know Boris Behncke during my high school years. He’s a geophysicist situated in Sicily, Italy. And to our fortune he’s quite keen on photography and shares these gems on various platforms. The latest paroxysm produced a very special event: That moment, […]
