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 encyclopedia 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?

Isaac Newton (1642〜1727)

A British physicist and mathematician. He is hailed as one of the Three Great Mathematicians. His first great discovery (the spectrum of light) was finding that white light was an amalgam of monochromatic light. Next, using his Universal Law of Gravitation, he successfully mathematically proved that planets move along elliptical orbits. The significance of this was explaining the movement of celestial and terrestial bodies under one law. The manuscript of his collective theories, 'Principia', took the world by storm, and Newton went on to obtain immutable fame. In 1705 he was knighted and known henceforth as 'Sir Isaac Newton'

Renowned invention: Newtonian telescope
Christiaan Huygens (1629〜1695)

A Dutch physicist and astronomer. His father was a government official affording him the highest standard of education. In 1655 he conceptualised a method of polishing lenses, which he demonstrated in action with the production of a high fidelity refracting telescope. Huygens valued quantitative observation leading him to invent the 'pendulum clock' in 1656, and the 'minimeter', capable of making measurements accurate within seconds, increasing the precision of observations. In the field of optics he opposed Newton's particle theory of light, asserting that it was instead a wave, but he went unacknowledged.

Renowned invention: Pendulum Clock
Gottfried Leibniz (1646〜1716)

A German mathematician and politician. It was said that he demonstrated talent in mathematics from a young age and was unparalleled in mental arithmetic. He advanced Pascal's calculator design, conceptualising one capable of multiplication and division. Additionally, he developed infinitesimal calculus during the same period as Newton did. There was severe discord between him and Newton et al. over priority rights for calculus. The notations for calculus used today are those Leibniz himself once used. In 1700 the Berlin Academy of Sciences was founded at the behest of Fredrick I of Prussia. Leibniz became its first president.

Renowned invention: Stepped reckoner

...and more characters!

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!

PRINCIPIA: Master of Science reviews and comments

Early access review very good game, I look forward to seeing what it will give once finished. To argue a bit (I only played 3h for now): positives:-turn-based game system-posibilities of evolution whether in research, career or celebrity-there is a real work on scientific theories-addictive and simple to understand even for English. -tutorial-the IA. The other scientists wander on the map and do their own actions and research. -no bugs (I played only 3h) negative points: there are a lot of things to say about this game but it is in early access and inexpensive so it makes sense-the tutorial is fine but it only explains 1/10th of the game , we are quickly lost and it takes time to find what we can do in the game. -the fact of being able to realize only one action per turn. -the AI that sometimes decides to Pierce you unnecessarily. For example, another scientist challenged my theories 5 laps in a row while the Academy rejects their criticism every time. -not enough indications-repetitive and not fast enough on the phases between the towers. I will continue to follow this game hoping for updates and a French version (although I do not believe too ^^)

Early Access Review Simulator of goat and intrigue between scientists in the 2nd half of the 17th century:) The idea is to make discoveries, earn fame and at the expense of her points to build a career and climb to the top of the scientific world. The Winner is the first to write a treatise on the gelecentric structure of the solar system. In practice, even as president of the French Academy of Sciences, it is not always possible to protect their discoveries, and envious, trying to disprove the old discoveries or just insult and take a couple of moves, so a pond. Pluses:-Relative freedom of choice of actions: it is possible to engage in discoveries (experiments and theoretical reasoning are connected, but it is possible to lead them in different order), to improve the skills of training in universities, to earn lectures, To buy all kinds of scientific devices for the laboratory, to travel within Europe, to build relations with other scientists (to send them money/bribe or vice versa, to insult and to put in doubt merits), to improve a career. -Learn the history of discoveries of this period Cons:-Tutarial is simple and does not reveal all aspects of the game-the Music is primitive and quickly bored-Not transparent game mechanics-not always clear because of what the academy rejected your discovery-No duels to kill A competitor/dependant, you have to wait for his natural death or at least re-election at the academy to push through some discoveries. For such money a normal way to kill a couple of three evenings
