usually when we visit a place, there’s one thing people say you “must” do — and in taipei, that is probably climbing the taipei 101 and seeing the city from high above. more than the views though, the big skyscraper has one interesting feature that i really wanted to see: the tuned mass damper! brady from practical engineering explains how it works, on this funny old video:

the thing is just a huge, super heavy pendulum that absorbs the building’s movements to counter the oscillation from winds or the ground motion. there’s plenty of movies on youtube of it swinging during typhoons or earthquakes — including during the 2008 sichuan earthquake we felt in shanghai. 

i think it’s brilliant that they gave it a spotlight and turned into a feature that everyone can visit — hurray for making engineering visible! i often think of how many things like this exist, and how we’re not even aware of them, and of all the work and science that is involved in big and small things. 

oh, and i guess the views from up there are not bad either! :D
