2016 – a year when social media bubbles of misinformation and hate have grown and risen to the surface, as much as to change the world, bringing even more sorrows and worry and exposing a fragility of a civilised society. It is tempting go hiding in our own privileged bubbles, unable to take in more evil madness.
In my own privileged world, I have also seen many examples of social media bubbles full of friendship and support, not only with families and friends, but also bubbles with teachers sharing ideas, materials, joys and concerns in Facebook groups, asking for help and getting supported, with discussions involving teachers from preschool to university. These bubbles provide a glimpse into the very different realities across the school system, but also offering opportunities.
During 2016, our Physics Education Resource Centre has also run two conferences, attempting to bring bubbles of research and practice in closer contact, for physics teaching across the education system, and for science in preschool. I have been in bubbles of roller coaster enthusiasts, e.g. in the Wildfire at Kolmården, and at the Euro Amusement Show, and in bubbles of amusement park teachers – at Liseberg, Gröna Lund and Tivoli gardens, and presenting the project in a bubble of science communicators e.g. at Göteborg International Science Festival , and in clusters of bubbles looking into various aspects of smartphone use in teaching.
Social media can be a power for good and evil. On the eve of a new year, I wish you all bubbles rising for a better world, with more open horizons.
Last week, I was in Vienna, invited to talk about Physik im Prater und auf dem Spielplatz at the 70th annual “Fortbildungswoche für Lehrkräfte aus Physik und Chemie”, arranged by “Der Verein zur Förderung des physikalischen und chemischen Unterrichts”
I made sure that I arrived to Wien in time to do some research before the presentation, to know which examples would be relevant, take some ride photos, and, of course, collect ride data from the PraterTurm, as complement to the data in the recent paper about Rotating Swings – a Theme with variations.
The walk towards the PraterTurm passes many other rides, starting with the classic Riesenrad, and a few entangled roller coasters. The photo below shows clearly the saw-toothed track part of the “anti-rollback” device, which causes the familiar click-click sound as the roller coaster train ascends the lift hill. Continue reading
Andreas Andersen greets Werner Stengel
See more pictures from the visit of Dr Stengel and family in connection with the Helix opening.
On April 23, few days before the official opening, the European Coaster Club (ECC) and the press had the opportunity to try Helix. In honor of the day, I put on helix braids, complete with Liseberg rabbits. I also brought along an accelerometer and measured the forces on the rider, middle, front and back.
Already, the week before, I was allowed to put an accelerometer on the front seat of an empty train. (View graphs of the resulting data and more about
