Fiscal paradise Updated 2025-07-16
Fiscal paradises must be invaded and destroyed.
Fish Updated 2025-07-16
This paraphyletic subgroup is easy to form the "acquatic only" (fishes) vs "things that come out of water" (tetrapods). Though mudfishes make that distinction harder.
Which kind of makes sense, why would you want for limbs unless you are going to stay out of water!
Fishers of men Updated 2025-07-16
Gospel of Matthew 4 King James Version:
18 And Jesus, walking by the sea of Galilee, saw two brethren, Simon called Peter, and andrew the Apostle his brother, casting a net into the sea: for they were fishers.
19 And he saith unto them, Follow me, and I will make you fishers of men.
Fish subclade Updated 2025-07-16
Once Ciro joked in a twenty questions-like game that humans are animals.
But counting humans a fish would have been a stroke of genius.

Supports only very basic effects it seems: chorus effect and reverberation. The main way to add instruments to it is via SoundFont files.
Fourier series Updated 2025-07-16
Approximates an original function by sines. If the function is "well behaved enough", the approximation is to arbitrary precision.
Fourier's original motivation, and a key application, is solving partial differential equations with the Fourier series.
The Fourier series behaves really nicely in , where it always exists and converges pointwise to the function: Carleson's theorem.

But what is a Fourier series? by 3Blue1Brown (2019)

Food without photosynthesis Updated 2025-07-16
This is the future of course, fusion power to generate electricity, and then converting electricity into food somehow.
Hopefully without going through photosynthesis, which feels complicated and wasteful.
Formal proof is useless Updated 2025-07-16
The only cases where formal proof of theorems seem to have had actual mathematical value is for theorems that require checking a very large number of case, so much so that no human can be fully certain that no mistakes were made. Some examples:
