Science is great, Copenhagen is great – so what’s better than walking in Copenhagen while talking about science!?

About Science Tours CPH:

Hi! I’m Johanne, I make science walks, talks, guided tours and anything related to the history of science and tech – and founded Science Tours CPH. I love all the fabulous stories, fun facts, quotes and myths related to science. I’m also a mother of two, an MSc. in physics and a science teacher based in Charlottenlund, just north of Copenhagen. I teach physics and mathematics at a high school in Østerbro, Copenhagen, and mathematics at DTU, The Danish Technical University. In particular, I find it interesting how science develop. Often, it is really surprising stories, entirely different from what you expect. I strongly believe, that – a long stretch of the way – these matters can be explained in a non-complicated way to anyone who is curious. That is exactly my primary goal of Science Tours CPH; to explain the science in an easy-to-comprehend way, without compromising the science!

Update spring 2021:

What have I been up to this last year, the Corona year, that did not do a whole lot of good to a new busines of science tourism? Well, it’s not all that bad! In the spring of 2020 I engaged myself in the exciting course History of Quantum Mechanics at the Niels Bohr Institute of the University of Copenhagen. This course is highly recommendable! Brush up on the foundation of quantum theory and quantum mechanics – wow! Reading the original works of Einstein, Planck, Bohr, Schrödinger and Heisenberg is exciting, hard work and just amazing and surprising in a very nerdy kind of way. The equations that I had worked with earlier in my studies made so much more sense, when taking the historical approach. In the summer of 2020, I participated as a guide at the exhibition in The Round Tower in Copenhagen: “H.C. Ørsted anew – The Beauty in Nature!” in celebration of the 200 years of electromagnetism. It was great fun and very giving to talk to so many visitors in the Round Tower. The exhibition showed with great clarity the importance of Ørsted’s contributions to physics, chemistry and medicin, and his invaluable rôle in science development in Denmark. For a while, I have -like so many other teachers- been working from home on Zoom and Teams, trying to teach my students from afar (“So, class – who’s got a thermometer, kitchen scale and some nails at home? Let’s measure the specific heat capacity of those nails… in your kitchen… yes, you may use a potato instead of nails”).

Update fall 2021:

This semester (fall 2021) we have been lucky to be back in school, which is such a releif -on the whole a much better teaching environment than sitting alone online on Zoom in front of the screen. Also, I am now a math teacher at DTU, The Danish Technical University – great fun to teach university levels and a good opportunity to read up on my linear algebra, complex numbers and differential equations! And finally – finally! -science tourists are back – I am so greatful! Winther is coming and Copenhagen will dress accordingly with lights , stars, hearts and Christmas trees everywhere – and maybe snow (I hope!). A good time to stroll through town and talk about science!
