PRINCIPIA: Master of Science is a simulation game with the theme of European science in 17th century. Choose one of 12 real scientists from the era of Isaac Newton and proceed with your research. There are six research topics: "Astronomy", "Physics", "Thermodynamics", "Biology", "Optics", "Mathematics". Choose one (or more), perform experiments, make discoveries and submit your findings to the Royal Society of Sciences. It's even possible to belittle your rivals. Fill and complete your own encyclopaedia with inventions like "Pendulum clock" or "Reflecting telescope", or sketches like "Enlarged view of a cork" or "Enlarged view of a flea"! It is the time even the word "Science" did not exist. Who can be the master of science? ------------------------------ This game is developed originally for the software contest held in 2000 as "PRINCIPIA". Since then, all aspects of the game are improved including the system, graphics and sound. Also the current version has "Final theme", "Order of merit" and more. It is completely different to the original version. The game follows actual history very closely, so you can also learn the history of science while you play the game. All six songs were recorded in the studio by a real string quartet. These live performances suit the 17th century aesthetic very well. If you are interested in Science, this will be a fun game for you!
