Discoveries & Inventions
 the law of the pendulum: This later was used to
regulate clocks
 Telescope: 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
 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 Pisa
 I proved Aristotle's law of nature, that heavier objects
fall faster than lighter objects to be false.
