I am Francis Bacon, and i invented the scientific method. Without it, it would be harder for people to know how to approach an investigation. My invention is the foundation to the modern scientific method.
I am Nicolaus Copernicus and I was the first one to develop the heliocentric system concept. Everything people know about the universe couldn't have been made without my concept.
I am the scientist Isaac Newton and i established the theory of the existence of gravity. Gravity is very important that that's how we understood the basic of physics.
I am Rene Descartes, and i am considered the "Father of Modern Philosophy"
I am Johannes Kepler, I realised that the planets orbit in elliptical order
I am Galieleo Galilei, i followed the studies of Nicolaus Copernicus and Aristotle and put my thoughts in writing and published them. I was executed by the church but i know that without my writings, people would never know what we know now.
