Without going into religion, it’s also mildly interesting for the defining veganism.

I've been in discussions with vegans over the 9.1x10^2 to 1.3x10^8 bacteria in the average indoor m^3 of air.

sure, but a copepod is a lot closer to a shrimp than bacteria.

Just imagine, you could have been born as one of quadrillion of these guys, but instead you are a human, that’s more than lottery luck we all got, if you can read this.

Or maybe it's all still just a matter of perspective:

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…

That device is called the internet ;)

These pics remind me of an indy game way back on the PS3 called Flow[0]. It was designed as a low stress, low impact, and a fairly calming game. You were a small underwater creature that swam around collecting things to become a bigger creature. You used the 3-axis feature of the controller instead of the d-pad and joysticks.

Reminded me of Osmos: https://www.osmos-game.com/

Unless he has considerable rabbinic training, Walter is not competent to judge whether the (invisible) copepods are kosher or not. The categories in the religious laws have some connection to biology but are not determined solely by physical conditions either. At the risk of over-simplifying, these laws are meant to be possible to follow. Nobody is going to decide that, henceforth, all strictly observant Jews must fi…

Here's my favorite story about scientists judging what's kosher, starring none other than Richard Feynman: One day, two or three of the young rabbis came to me and said, "We realize that we can't study to be rabbis in the modern world without knowing something about science, so we'd like to ask you some questions." Of course there are thousands of places to find out about science, and Columbia University was right ne…

The followup anecdote in that same article was also fun:

I decided to trap the students in a logical discussion. I had been brought up in a Jewish home, so I knew the kind of nitpicking logic to use, and I thought "Here's fun!" My plan went like this: I'd start off by asking, "Is the Jewish viewpoint a viewpoint that any man can have? Because if it is not, then it's certainly not something that is truly valuable for humanity... yak, yak, yak." And then they would have to say, "Yes, the Jewish viewpoint is good for any man." Then I would steer them around a little more by asking, "Is it ethical for a man to hire another man to do something which is unethical for him to do? Would you hire a man to rob for you, for instance?" And I keep working them into the channel, very slowly, and very carefully, until I've got them - trapped! And do you know what happened? They're rabbinical students, right? They were ten times better than I was! AS son as they saw I could put them in a hole, they went twist, turn, twist - I can't remember how - and they were free! I thought I had come up with an original idea - phooey! It had been discussed in the Talmud for ages! So they cleaned me up just as easy as pie - they got right out.

Wait a moment and think about how you are made of meat. https://www.mit.edu/people/dpolicar/writing/prose/text/think...

There even is a spooky skeleton inside of each of us :|

Sometimes I look over at my wife sleeping in our bed and think about how I am sleeping next to a skeleton.

Or the bacteria and fungi constantly living and dying within us. The self cells we continually turn over and instruct to die. The second order predation that balances the ecosystem that sustains us.

Orcas that enjoy playing with their food. Lions that eat prey alive. Beautiful and terrifying. Our primate and hominid ancestors that ate the flesh of rival clans.

I respect veganism and personal choices, but the world is a big place with lots going on that will forever escape our ability to control. That's how I frame my own decision, but I respect others' too.
