The earliest microscopes were called flea glasses because they were predominantly used to observe small insects such as fleas! These microscopes were simple in construction, using different shapes and sizes of glass with low power (6x to 10x). They were invented by the Romans.
The flag of America that we’re familiar with today is the longest-running unmodified version the US has had – and it’s gone through a total of 26 iterations! The first flag was the Continental Navy ensign, which looks similar to the current flag except for its fewer stars, which are arranged in a circle rather than in lines.
You’ve probably heard the notion that diamonds are forever, or maybe you can even hum along to the popular song of the same title.
