Am 26. September 2025 ist wieder Kinder-Universität an der Universität Potsdam. Ich bin wieder mit zwei Vorlesungen dabei, "Knochenjob in Ostafrika–Unterwegs auf den Spuren der ersten Menschen" und "Was war los im nördlichen Afrika, bevor es Pyramiden gab?". www.uni-potsdam.de/de/medieninf...

Today marks the start of the 60th compact course based on my textbooks #MATLAB Recipes for Earth Sciences, 6th Edition (Springer 2025) and #Python Recipes for Earth Sciences, 2nd Edition (Springer 2024). I am looking forward to this new round of teaching online! mres.uni-potsdam.de/2024/10/23/o...

Artificial neural networks (ANNs) have been used for quite some time to identify, for example, flowers in easy-to-use apps on smartphones. Here's an #ANN with backpropagation in 6 steps, now with both #MATLAB and #Python code: mres.uni-potsdam.de/2025/09/08/a...

Multispectal imaging captures images across multiple spectral bands. Here is a #MATLAB example using #MAPIR cameras where eight different spectral bands in visible light and near infrared show differences in a rock sample that are invisible to the human eye. tinyurl.com/bd9by86r #geoscience

Thanks to the ongoing support of MathWorks Inc. through their Curriculum Development Program, I was able to purchase two more spectral cameras. Here is an example of how to import and process the images of an agate druse sampled from a Permian basalt in #MATLAB: tinyurl.com/54umubv4 #geoscience

Due to two cancellations, we have reopened the registration portal for you! As always, it's about 15-20 people online, lectures and live coding sessions, prerecorded on the course website and you can work on exercises and an individual project to get up to six credit points! shorturl.at/VzWLn

More than 30 years ago, I began teaching courses on data analysis in the earth sciences. 20 years ago, I started thinking about writing textbooks. Now there are six textbooks and many different course formats for you. Here are the options for you: mres.uni-potsdam.de/index.php/20... #geosciences

KIND workshop last week in Potsdam (Germany): 65 scientists from all over the world gathered in Potsdam discussing ideas for scientific drilling of Lake Kinneret to address question of paleoclimate variability and its link to human evolution ℹ️ www.icdp-online.org/projects/by-...

As part of upcoming ICDP KIND workshop this weekend on Lake Kinneret Drilling, I will give a presentation on climate time series analysis, methods, and applications. I have compiled a list of courses, books, and papers by us during the last decade: mres.uni-potsdam.de/2025/07/09/r...

Yesterday, I had a visit from an 11th grade class from a high school. I gave a talk on the climate tipping point 5,000 years ago and ancient Egypt, and had the students solve some problems using AI. It was alarming to hear that AI is not a topic covered in class. #geoscience

Potassium is a proxy for aridity in Chew Bahir, Ethiopia, due to the increasing illitization of smectites in a gradually drying lake. V Förster and colleagues have investigated this in detail—and last year we showed that this was even the case 379 kyr ago, as found at a core at 200 m. #geoscience

If you are looking for an international #Master's program in #Geosciences without tuition fees, with many courses in modern data analysis, remote sensing and geo information systems, the @unipotsdam is the right place for you! www.uni-potsdam.de/en/geo/study...

We still have a few spots left for our online short course on my books, now of course also featuring AI applications. See you in September! mres.uni-potsdam.de/2025/04/29/6...

Compositional data often show dilution effects, which can be corrected by using (log-) ratios. Unfortunately, the desired goal and the method used often do not match in paleoclimate studies. Here's a series of simulations to illustrate it. #aitchison #geoscience mres.uni-potsdam.de/2025/05/29/m...

Interested in exploring different mathematical tools, including #recurrence_plot analysis and tensor-based methods, to uncover patterns in multiscale or incomplete data? Here is your opportunity (@maastrichtu.bsky.social) vacancies.maastrichtuniversity.nl/job/Maastric...

Yesterday and today, I taught a class for ~11-year-old children. The topic was the end of the Green Sahara and the first pyramids 5,000 years ago. First, we used an #AI image generator to create a cover image showing the #Pyramid of #Cheops at the time of its construction – where is the mistake?

Wissen zum Bier präsentiert die Uni Potsdam vom 19. bis 21. Mai in drei Potsdamer Pubs und Cafés. Damit beteiligt sie sich erneut am weltweiten Wissenschaftsfestival „Pint of Science“ #pint25, bei dem Forschende in lockerer Atmosphäre ihre Themen vorstellen: www.uni-potsdam.de/de/medieninf...

Am 19. Mai 2025 bin ich einer der Vortragenden im Café-Bar 11-line in Potsdam, zusammen mit zwei weiteren Kolleg:innen von der U Potsdam im Rahmen des diesjährigen Pint of Science Festivals. Was war los im nördlichen Afrika, bevor es Pyramiden gab? pintofscience.de/event/potsda... #Geosciences

You get a very nice result if you ask ChatGPT to write a few lines about the combustion engine in Shakespearean style.

This is what happens when you upload a photo of yourself to #ChatGPT and ask it to turn you into a Playmobil figure. The AI makes you look younger, that's a default setting, very flattering! #Geoscience

Amidst all terrible news, I am sad that here it is not better. Today the VU Amsterdam announced they'll cut Earth Sciences, and fire 39 staff. 130 students are left to figure out how to finish, and an unknown number of PhDs lose their supervisors. My heart goes out to my colleagues 😳😥

Agate druse, basalt, "melaphyr", 290 million years, Permian, Waldhambach, Germany, shot with a Nikon Z fc with a Nikkor Z MC 50 mm 1:2.8, auto focus. Width of the druse is about 10 cm. #MineralMonday

This is the underside of a siltstone layer with beautiful trace fossils, Middle Cambrian, Äleklinta, #Öland, Sweden. Other trace fossils and trilobite fragments can also be found there. #FossilFriday #Geoscience

Python indexing starts at 0, not 1. As an example, to create an RGB composite of Bands 29, 23, and 16 of hyperspectral EO-1 Hyperion images, you have to type HYP1 = HYPR[:,:,28] HYP2 = HYPR[:,:,22] HYP3 = HYPR[:,:,15] How do you avoid indexing errors in remote sensing with Python? #Geoscience

After writing a ~500 pages book in two versions for MATLAB and Python, I would like to offer a comparison from the point of view of a MATLAB user. #Geoscience mres.uni-potsdam.de/2025/03/21/m...

Now that the MATLAB version of my data analysis book has been released, you can put this book next to the Python version from October 2024 and use it as a MATLAB-Python dictionary. #Python with numpy and scipy copies #MATLAB, codes are the same. #Geoscience mres.uni-potsdam.de/2025/03/21/u...

The 6th edition of MATLAB Recipes for Earth Sciences was published yesterday, 14 months after submitting the manuscript to @springer1842.bsky.social. At least they allowed me to update all the #MATLAB codes and change the copyright year to 2025. #Geoscience link.springer.com/book/10.1007...

Apology accepted 😉

Live streaming smartphone sensor data to #MATLAB desktop was great fun but a lot has changed since my first post on the topic in 2017, both with MATLAB Mobile and Desktop. Here is the update, it is still great fun! mres.uni-potsdam.de/2025/03/14/m... #Geosciences
