I just published a new video in my lecture series on X-ray tomography (link). There I show how to use Matlab to simulate basic tomographic things such as sinograms and filtered back-projection algorithms. I also give an introductory discussion of measurement noise and how to supress it with a low-pass filter. This is how it
I was lucky to be invited again to the legendary Mathematisches Forschungsinstitut Oberwolfach (MFO). This time the topic of the five-day workshop was tomography, or mathematical slice imaging. How delightful it was to meet collaborators and share ideas after the pandemic years of online meetings!
I gave a talk in the “Math Encounters” series at the Museum of Mathematics in New York City in February 2023. My topic was X-ray tomography. Now the video recording of the presentation is available! Enjoy!
I co-organized a workshop in March 2023 at the Isaac Newton Institute in Cambridge: https://www.newton.ac.uk/event/rntw02/ It was so nice to see many colleagues after a long break! Instead of a regular scientific talk, I gave a presentation by title “Science Showmanship”. It contained some scientific stand-up comedy and stories about being a mathematical YouTuber. In
My entertaining, yet scientifically accurate video series continues. It’s my educational experiment with material that serves both science popularization and academic teaching. Enjoy!
The Finnish Nuclear Society elected me to represent University of Helsinki in the Board of 2023. I am really excited about this position at the time of the world’s first geological disposal (in Finland!) of spent fuel and the rise of small modular reactors (SMRs). Nuclear energy plays a significant role in the transition away
I made a fun X-ray tomography video about pi. Enjoy! (And make sure to subscribe to my channel Professor Sam)
I started as Treasurer of European Mathematical Society in 2023. After some preliminary gatherings and Zoom discussions, I am now taking part of my first Executive Committee meeting. So I’m in Copenhagen discussing a long but exciting list of activities and decisions of the EMS. Cool!(I promise not to apply my personal investment strategies at
I gave a popular math talk at Museum of Mathematics in New York City on February 8, 2023. My presentation was part of the Math Encounters series, where previous speakers include Terence Tao, Stephen Wolfram, Ingrid Daubechies, Jordan Ellenberg, Cathy O’Neil, Steven Strogatz and Hannah Fry. My topic was X-ray tomography, and I included a
I lectured a minicourse on the mathematics of X-ray tomography at the winter school Advanced methods for mathematical image analysis in Bologna, Italy. It was such a nice week! About 70 young scientists arrived to learn about the mathematics of imaging. Including three of my own PhD students, namely Elli Karvonen, Salla Latva-Äijö and Siiri
