Science is great, Copenhagen is great – so what’s better than walking in Copenhagen while talking about science!? It is not just the science – interesting and mind blowing as it – but the history of the science is a whole fairy tale book on it’s own (without the fairies).

Hi! I’m Johanne de Leon. I am quite nerdy about collecting the fun facts, quotes, myths and fabulous stories related to science. And so, I do science walks, talks, guided tours and anything related to the history of science and tech. I’m also a mother of two, an M.Sc. in physics and mathematics and a science teacher based in Charlottenlund, just north of Copenhagen. In particular, I find it interesting how science develop: It is often surprising stories and not as complicated as you may think! Well, often, anyway. 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 my primary goal of Science Tours CPH; to explain the science in an easy-to-comprehend way, without compromising the science. It’s “the idea of the science” and the “how did it happen?”. That’s what we want to get to. It is key for me to stay true to the theories, the historical knowledge of the field, and that means taking the time to investigate, find primary sources and stay in touch with research. The short version or the long version – you chose. There is certainly enough fun anecdotes on all levels!

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.

And now, I hope to see people againg soon in Copenhagen! We have so much to offer here! Tourists, come and learn! While I wait, I have my piles of books on the history of science and springtime invites to explore the city with my family. I will -like so many other teacher- be 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”). I am so looking forward to real teaching in classroom and lab and to those summer science walks in Copenhagen.
