Can go directly upwind (no tacking required). Can also be applied to boats.

99 what you did there...
(I know, IC isn't valid Roman numeral representation of 99, but it was the only joke I could think of.)
Because it's not an X at the end, it's a Greek chi. Same with the arXiv preprint distribution
it's "archive," not are-ex-iv.
Anyway, here's Wondersmall.
I'm drunk, and it's all Mexico's fault!
Sorry you're getting down voted
lots of replies from folks unclear on what the diffraction limit means, atomic resonances, etc.: https://www.newscientist.com/article/2161094-a-single-atom-is-visible-to-the-naked-eye-in-this-stunning-photo/
Parent didn't say resolve, they said see
you can't resolve stars but you can most certainly see them.
Light up a single atom enough and you can see it (unclear if this works with a dark adjusted naked eye or if a long exposure is required): https://www.newscientist.com/article/2161094-a-single-atom-is-visible-to-the-naked-eye-in-this-stunning-photo/
No, they're too small to resolve. You can see small things if they're bright enough: https://www.newscientist.com/article/2161094-a-single-atom-is-visible-to-the-naked-eye-in-this-stunning-photo/
A single atom of gold is far too small for any photon in the visible spectrum to interact with.
That's incorrect
single atoms can, and do, interact with optical photons.

And the entire field of super resolution microscopy relies on small things (e.g., molecules) interacting with light.
Are we talking fediveese hackers? You know, the socialist-furries-with-UNIX-socks hackers?
Those folks hate cars, not trains. I don't think we need to worry.
