• Unexpected Delays on the Road to Zadar: A Travel Story

    On our last leg to Croatia from Maribor to Zadar we were expecting an easy and relatively short ride of 400km. We could not have been more wrong. After 50km towards the border the gps started to show alerts about traffic jams ahead and delays increasing into the +2 hours range. We decided to exit the highway and take smaller roads to avoid the traffic jam. That worked well but the roads in Croatia are not really made for making a lot of headway, endless changes in speed limits without any obvious reason seem to be there to make you…

  • Selling Second-Hand Books: My First Experience with BoekenBalie

    I had a long weekend free and decided to complete my library dabase. In the process I discovered a couple of books I have 2 copies of. Some time ago we were discussing with friends about buying and selling second hand books and they were using BoekenBalie because it is an easy process to sell your books with them. The process is indeed easy, create an account, download the app and you can scan the ISBN codes of the books you want to sell. The app immediately gives feedback about the expected price they will pay you for the book…

  • Hotel Citymap and Jack & Joe Steak and Burger Club in Maribor

    Our second stop on our way to Croatia was in Maribor. We stayed in the Citymap Hotel which has free parking and 2 low power charging stations. They didn’t work with my charging card which was one of the exceptions on our trip. But it did accept my credit card so I was able to charge overnight and we had a full battery in the morning for our last leg to Croatia. We had a family room which was spatious enough for 4. The view through the window was towards a backyard, not very beautiful but we arrived late and…

  • Wels Steak and Grill in Austria

    During our trip to Croatia last summer we were traveling from Regensburg to Maribor and had to find a place to charge and have lunch. We passed Wells and looked for a place to charge. It turned out there were some free charging stations next to a shopping mall and and a movie theatre. At the move theatre there was also a restaurant, the Wells Steak and Grill. Because of the doubtful weather the terrace in front was closed and we had to sit inside. In terms of interior decoration it was nothing special as can be expected but we…

  • Joan as Police Woman in Leuven 2025 Concert Review: A Night to Remember

    On November 24 2025 Joan as Police Woman played a concert in 30cc in Leuven. I saw her play in Leuven long ago in the period that she had released Real Live and To Survive, 2 albums I have at home and really like. I hadn’t followed newer albums so I didn’t know what to expect. But even if I had been in touch with her more recent albums I doubt it would have prepared me for her performance. Joan played keyboards and piano and a bit of guitar and was on stage with only a drummer and a guitarist.…

  • Premier Inn City Center Hotel and restaurant Meridiano Regensburg

    During our summer vacation we went to Croatia. On our way to Croatia we made a first stop to sleep at the Premier Inn in Regensburg. It is called the City Center Hotel but the neighbourhood looked more like some kind of business district with very little activity when we arrived. That probably explained the low rate we had to pay for the 2 rooms which were modern and clean. Breakfast in the morning was good and the hotel has an underground parking garage with number plate recognition. If you don’t mind not being in the city centre this hotel…

  • Evariste Galois. 1811-1832, Laura Toti Rigatelli (ISBN 978-3-7643-5410-7, Birkhäuser)

    I found this biography of Evariste Galois after reading about him in Eric Temple Bell’s Men of Mathematics. It is part of the Vita Mathematica series of the publisher with biographies of mathematicians, most of them published in German. The author is an Italian professor in mathematics with a special interest in the history of algebra. Galois made ground breaking contributions to algebra and his short life was mostly lived in the turbulent years after the defeat and exile of Napoleon. France was split between the royalists and supporters of the ideals of the Revolution. Galois’ father had been a…

  • Richard Feynman. A Life in Science, John Gribbin and Mary Gribbin (ISBN 978-1-78578-372-2, Iconbooks)

    During my physics studies at university I became a fan of Feynman. His path integral formulation of quantum mechanics was a revelation after years of plodding through the standard formalisms by Heisenberg and Schrödinger and the mists surrounding the question what it all meant physically. Especially the fact that this approach was also applicable to classical physics was, I say it again, a revelation. But I didn’t know much about Feynman as a human being. That changed when I read the biography from James Gleick. in the middle of the nineties. That biography is lengthier and more detailed in the…

  • Exercised. Why something we never evolved to do is healthy and rewarding, Daniel E. Lieberman (ISBN 978-0-525-43478-8, Vintage Books)

    I heard about this book in a podcast about running. 2 journalists discussed their own running habits and struggles and one of them mentioned this book as a good one to read. I definitely found it interesting as it gives insights from an evolutionary perspective to why so many people struggle to exercise even though everyone knows it is good for your health and quality of life. The author is a paleoanthropologist and professor of human evolutionary biology at Harvard University. The book is well written and researched with many references to research papers. I learned a lot about human…
