Das Weltgeheimnis by Thomas De Padova is not quite an international best seller, at least I didn’t find an English version of the book. Nevertheless for those who speak German and who are interested in natural science it is a very enjoyable book.
De Padova tells the story of Galileo Galilei and Johannes Kepler, two remarkable figures of history who changed how we saw the world and the universe in which we live.
Kepler lived and worked many years in Prague, back then the centre of the Habsburg Monarchy. With endless patience Kepler analysed Tycho Brahe‘s observations of stars and planets and thus found the Laws of Planetary Motion.
Galileo Galilei is most famous for the heliocentric model. Though he wasn’t the first one proposing a model in which the sun, not the earth, is the centre of our planetary system he and Kepler were two important personalities arguing for the model.
Among many interesting things, there are three things I’d like to point out here.
First, it’s amazing under which conditions and with which persistence scientists and philosophers in the 17th century changed the world. They started a process which would accelerate through the 18th, 19th and 20th century until the present day (and it is still accelerating).
Second, many chapters about Kepler give a little bit of inside into how life must have been in Prague in the 17th century. It was the capital of the Habsburg Monarchy and thus for a huge part of what we call Europe today the centre of the world. Two world wars and 40 years of communism change things a lot…
Third, in the story of Kepler and Galileo you recognize all to well the principle of “the adjacent possible” described in Steven Johnson’s awesome book “Where good ideas come from“. Galileo and Kepler both were able to build on top of Copernicus. Kepler based his analysis and calculations on Brahe’s extensive data collection. One generation later, Isaac Newton referred to Galilei’s and Kepler’s findings…
The history of science is an exciting story to tell and Thomas De Padova tells it well.
If you are interested in science books: I’m currently reading “A Short History of Nearly Everything” by Bill Bryson. I’m not yet finished with it, but Bryson is a brilliant narrator and I highly recommend to get a copy (of the book, not Bryson…).
