Discoveries & Inventionsthe law of the pendulum: This later was used

to regulate clocksTelescope: This took many years to create

but with this invention I was able to discover what you all know to be called sunspots. These sunspots showed that the Sun is on an axis and with that discovery I was able to discover that the Earth is on an axis as well. This invention also made the discovery of Jupiter's moons, that Venus went through phases

Discoveries & Inventions (Continued)Law of Inertia: Most objects that are in a

state of motion do Not stay in that state of motion.

Along with the telescope I invented the thermometer and magnets

Tower Of PisaI proved Aristotle's law of nature, that

heavier objects fall faster than lighter objects to be false.
