Observations & Facts / Laws / Hypothesis & Theories

Sir Isaac Newton’s Law of Gravity

Observed all objects in universe exerting gravitational force on each other

Force between objects increases as MASS increases Force between objects decreases as DISTANCE b/w incr.

Is Science = Technology?

Closely related: often advance together

lens, spotting scope, telescope & Galileo

new inventions often lead to new discoveries

laser invented prior to having a use for it
