A (tongue-in-cheek) proposal that the set of natural numbers is finite?

A while back I read a fascinating paper by a real mathematician (read: not a crank) who made the claim that the set of natural numbers is in fact finite. It was an entertaining read, but somehow I didn't bookmark it and I haven't been able to turn it up again. I'm hoping someone else at MeFi knows of it. [more inside]

Is there a Lichenologist in the house?

I found some branches with some beautiful lichens on them, and I want to use them in the house in dried plant arrangements. But! I don't want to poison my family with spores/pollen, or allergic reactions. Did some searching but would also like to get input from anyone learned in the fields of mycology, phycology, microbiology, and/or botany.

That’s some good ink, bub.

Microfiber Laundry Ball: Is it BS?

I saw these microfiber laundry balls in a store recently and was intrigued. My question: Is this bullshit? Would it actually help the environment if I bought and used one, or would it just make me feel good? Non-PR sources preferred.

AirPods in my bra ?

I’ve recently had to buy AirPods and they’re very lose-able so I’ve taken to storing them (the case mostly) in my bra. I’ve always stored my mobile phone (cell phone) in my bra because it’s convenient and clothes made for women seldom have pockets. Is BraPod in any way a theoretical breast cancer risk? [more inside]

Modelling water flow - software

I'm seeking fluid modelling software, especially for water. I would like to do this at least partly in software as it takes more water flow than I can achieve at home. But what software? I need free, pref. FOSS, okay with cmd-line. I've looked at OpenFOAM but it's very hard to install, blender shows good graphics but I need realwater capability, and last time I tried blender 2009 it was hard to draw a polygon - also are Blender's water graphics 'real' or just pretty?! So what else is out there? [more inside]
