TIL A microscope can simply be reversed to make a telescope. Both telescopes and microscopes were in use in Holland by the end of the sixteenth century (www.bristol.ac.uk)

Optical Emgineer reporting in.

This is bullshite.

Read for yourselves:

What you can learn today is, that if you use a microscope "the other way around", something big is imaged into somethjng small on the focal plane.
Zeiss, a company that manufactures a shitton of optical stuff, has a very successful semi-conductor branch. That branch started off when some engineers from the microscope-department fiddled around with " inverted" microscopes during their lunchtime to create the first optics for lithography from Zeiss.

Source: i worked there. I know those engineers.

I'm a microbiologist and the first thing I thought is this is a person with a homework question asking why you can't flip a microscope to make a telescope. What better way to get the right answer than to confidently proclaim on the Internet bad information as fact? Then I was it's a bot copying content from Reddit and now feel gross.

Tbh that's in a modern sense, historically a microscope was just a single lense, which could be used for both (as far as I know). And the Dutch had the best lense makers and innovators that developed the optie technology early on.
