I wish there were a way to "productize" this, or automate it at least. I'm imagining some sort of aquarium-like tank you stock with ocean water that is able to maintain the microscopic life, allow them to flourish. Meanwhile, some sort of slow or periodic pump draws aquarium water into an attached, miniature "photography studio" where an appropriate camera+lens feeds a constant live stream to a display or to the web…

It's been done! Very niche market however. This is a tow-sled system for deployment from a research vessel.

Robert Hooke’s “Micrographia” had a really profound effect on the history of science. Here is the book— check out the letter to the king. I think people’s minds were blown and were ready to accept some new realities.

That frees the vision impaired a bit relative to people with good eyesight from a few things!

Does that mean blind jews can use this as precedent to eat whatever they like?

No, that would be silly. "The Naked Eye" is what normal human eyes can see without aid. There is a lot of grey area there, but microscopic creatures that you can only see with specialized equipment invented in the past 100 years certainly are not visable to the naked eye for any reasonable definition of naked eye.

> These tiny invertebrates can be found in the deepest ocean trenches and the highest alpine lakes, even in damp mosses and wet leaf litter. Walter once got a call from an Orthodox Jewish organization wanting to know if there were pieces of non-kosher creatures floating in the New York City tap water. The answer was yes. It’s hard to avoid these relatives of shrimp and lobster—Walter has studied them all over the wor…

The short answer is yes, except a tiny minority who require a filter that can filter the tiny guys. But it's a whole discourse.

Within reason, it's nothing, or `betal bshishim` which is equated to one sixtieth. It's void, as a concept, in Hebrew tradition.

It helps if you think about it in terms of historical hardships of the Hebrews. It means if you're hungry and your neighbor cooks for you and there's a tiny bit of non-kosher fat in the soup or something like that, or if you're starving, Yahweh will forgive you because it's such a small amount and you're so hungry it's not right to penalize you for that which you couldn't control. Something that is one sixtieth is colloquially so insignificant that it equates to nil.
