Here's another example of minimal coding: an artificial neural network (#ANN) with backpropagation in 6 Steps. ANNs have been the focus of great attention since the introduction of generative artificial intelligence (#AI) chatbots like OpenAI’s ChatGPT. mres.uni-potsdam.de/2025/09/08/a...

Computer code is becoming increasingly complex, making it difficult for beginners to understand. Here is an example of minimal #coding — that is, reducing computer code to the absolute minimum, just two lines of code to calculate a periodogram: mres.uni-potsdam.de/2026/07/19/m...

For three days, we celebrated DeepCHB, a new ICDP - International Continental Scientific Drilling Program initiative in the Chew Bahir Basin in southern Ethiopia, together with nearly 90 scientists from 18 countries. Let's go drilling again, this time 1.25 km deep into African's climate history!

The ultrasonic sensor from the Lego Mindstorms EV3 series measures the distance to an obstacle. Unfortunately, it only provides values between 0 and 255 cm in 1 cm steps. This is because the sensor contains an 8-bit microcontroller that can only output 2^8 = 256 different values. lnkd.in/dRUf986h

Why do some people still buy vinyl records when you can stream everything digitally these days? It’s not, as is often claimed, because they allow you to hear frequencies that are lost when music is digitized. No, it’s something else, as you can read here: lnkd.in/d4eUbz83

In spectrometry—for example, in remote sensing—Gaussian filters or, because they are believed to cause less distortion, Savitzky-Golay filters are often used to improve the signal-to-noise ratio of spectra. Read here to find out how to do it better: mres.uni-potsdam.de/2026/06/13/c...

AI changed everything, also the way we search for literature, create figures, and write summaries. Teaching a course on the scientific workflow and having published two editions of a book on the topic, it was time for a change. And two new books! mres.uni-potsdam.de/2026/06/10/c...

When I show my students that the sine of pi in MATLAB or Python is not 0 but 1.2246e-16, I usually see looks of astonishment on their faces. However, this result is not incorrect; rather, it follows the rules of floating-point arithmetic. mres.uni-potsdam.de/2026/06/07/w...

Yesterday I was standing in front of my bookshelf; it’s been 20 years since the 237 p. first edition of MATLAB Recipes for Earth Sciences, 77 figures and a CD-ROM 😉 , was published. How many copies do you have? What do you think of the Chinese edition on the far left? @springernature.com

Our new book entitled "Collecting, Processing and Presenting Geoscientific Information with Python" has just been announced by Springer Nature: link.springer.com/book/9783032... Provides an up-to-date introduction to the complete workflow of scientific work, with numerous examples, including AI.

A small group of students approached me and asked about a course on creative writing and public speaking. It turned into a very down-to-earth course right in the midst of the AI era—with plenty of coffee! Read about how it went: mres.uni-potsdam.de/2026/05/07/b...

Young people—as I was back then—do not really appreciate how quickly their valuable data, painstakingly created graphics, and carefully crafted texts can become unreadable. Here are a few thoughts on this and a recommendation: mres.uni-potsdam.de/2025/11/08/s...

Unfortunately, in many courses in geosciences worldwide, university-level mathematics and computational geosciences is not included, as my experience from processing this year’s masters applications suggests. mres.uni-potsdam.de/2025/11/07/h...
