  Not an expert but I’d guess that is Tycho crater, and the stripes are called its ray system en.wikipedia.org/wiki/Ray_system

  Nice work!

  I always found it funny to read it as Sharon, and now you’re telling me it’s named after someone called Charlene? This keeps getting better

  You could say something like “the image of exponentiation over…” to mean the set of values created by applying the function once, but it sounds slightly clunky.

  Looks like there aren’t really very many sets of mostly transcendental numbers that have names. Computational numbers and periods are two of them, I’d guess that both probably contain your set, so you could compare with those to see where it gets you.

• ⁨Comment⁩ on ⁨Closure of exponentiation of real algebraic numbers.⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  Fun question! I don’t know the answer other than to say it’s not just the algebraics because of the Gelfond-Schneider constant

  Are you sure this is well-defined? You say that a and b are algebraic but “closure” implies that they could also be any members of S. This might mess up your proof that it’s not all the reals if you do mean the closure.

  Don’t think I’d want to subject the poor spider to that, however funny it would be for onlookers!

  Always uplifting to see a struggling native species doing well. Hope I get to see one of these beauties up close one day, shame they are still limited to just a few locations.

  I thought that too as there is 1 planet too many, but now I think Pluto is the extra. The one between Mars and Neptune is Mercury

  It is pretty surprising that the UK has been put behind places like Sudan, Syria and DRC, so yes. Maybe we can blame the weather
