Nice, although I used that in grad school in the 80s for a prof that insisted on like 8 digits for all measures, even when, say, 2 were enough.

In solar system dynamics the product GM is always used, and that it known to considerably higher precision.

Which ones? I’ve never been able to get the hang of him, but am open to suggestions.

We think sluggish-lid convection explains the large polygonal cells in SP, but think the sea is too shallow in the south where there are no cells, but "bacilli" appear. With "rolls" I would ask boundary conditions that generate them & if they echo past not current conditions.

As the person who processed that image, I would love to hear more. We have not focused on the alignments, and if there's some there that is diagnostic of the climate/history/lifetime that would be awfully interesting.

Complex numbers map a 2D space, with a real and imaginary axis orthogonal to each other. There is no privileged status for "real" numbers. Given the immense power of complex analysis, it's a pity that people get hung up on issues of real/imaginary.

I can't bring myself to watch "Inner Light" again.

That happened in the future, so not yet.

"Imaginary" is an incredibly poor label. You posit that -1 = i * i and see what that does for you. Negative numbers, rational numbers can be considered to be just as artificial.

We’ve been able to do 1%, but the pixels are 4”. We still can’t get anywhere near Gaia.

More on Wolf 359, which New Horizons is going to look at. Nearby flare star, with two candidate planets. @NGC3314 notes that observers there can see the Earth transit the sun. Beside the STNG Borg battle, there's an Outer Limits episode based on it: en.wikipedia.org/wiki/Wolf_359_….

Which is why we're giving you a heads up! 🙂

And with two stars, we can do navigation of NH (well crudely). This will take stellar navigation into the interstellar regime.

This is the first ever demo of parallax with the stellar PSFs HWFM << parallax and simultaneous measures at both ends of the baseline, no proper motion corrections needed. The parallax displacements will be big and obvious
