Final answer:
Microscopes and telescopes are instruments that made scientific discoveries possible and helped ideas spread quickly.
Step-by-step explanation:
The invention of microscopes and telescopes played pivotal roles in propelling our understanding of both the microscopic and macroscopic realms. The microscope, pivotal in biology, allowed for the discovery of microorganisms and advanced medical knowledge through the observation of cells and disease-causing pathogens. This has led to the development of vaccines and a better understanding of health and disease. The telescope, invented by Hans Lippershey and popularized by Galileo Galilei, revolutionized astronomy by enabling detailed observations of celestial bodies, aiding in the formulation of fundamental theories such as Newton's laws of motion and Einstein's theory of relativity. These instruments made scientific discoveries possible helped ideas spread quickly and have greatly contributed to our current understanding of the micro- and macroscopic worlds.
