If no one looked, how would we know what’s there? But luckily, Galileo did. He made unbelievable astronomical, and mathematical discoveries. As well as advancements in physics and science. Galileo became very interested in spyglass and made his own telescope to see into space. With it he discovered craters on the moon, sunspots, the phases of Venus, and the four moons of Jupiter. He made one of his most notable discoveries on the pendulum. He noticed that the steady motion of a pendulum could help with timekeeping because keeping track of time was rare when he was alive. In 1602 he determined that the arc of a swing doesn’t depend on how far back it is or how much strength is applied. He later built the first pendulum clock. But Galileo was convicted of heresy because his theories discoveries what the church believed, so he was put under house arrest in 1632 and died in 1642 still under house arrest. Galileo had a major positive impact in his life and still does in ours. - Michael G.
