How to Calculate the Phase of the Moon
- huhtenberg 8y agoIllustrations like this one only serve to muddy the waters - http://witchy.co/triangle.png http://witchy.co/triangle.png The moon is lit from the wrong side and it has a crescent shape in what's basically an overhead projection. And it's not like there's much else going on in the illustration, it's one of its main elements.
- alanbernstein 8y agoYou're not wrong, and for the amount of effort put into this presentation, I'm surprised at this oversight. But if you can think of this image as a schematic, it's not a huge problem.

- thisacctforreal 8y agoFwiw it's 9KB, not 9K SLOC.
- delinka 8y agoIs this a common misconception? Personally, I assume KB in the context given.
- ngcc_hk 8y agoVery hard to read on my iphone
- bernardv 8y agoVery nicely done.
- dvh 8y agoSome time ago I calculated moon phase for date of birth for 90k users and I found no correlation.
- nurettin 8y agoI calculated gpa vs. date of birth, there is a very slight skew towards post-july being more apt in terms of gpa. Not sure if significant.
- jakeinspace 8y agoThat would imply a student being towards the upper end of the age cut off for starting kindergarten/elementary school (in the US at least, varying by state).
- chrisseaton 8y agoIf you calculated the moon phase from the date of birth how is it possible that the two are not correlated?
- dvh 8y agoI didn't found higher birth rates for any of the phase (split into quarters)
- na85 8y agoWelp, that was an infuriating scrolling experience on mobile. Why the fuck do people do this stuff?
- nicky0 8y agoI dunno, why do people insist on reading websites on mobiles? :)
- skilled 8y agoThe font seems to have an extremely strong glare effect in combination with other colors on the page.
- andai 8y agoThe font is made of sublimated astral magick.
- NamTaf 8y agoThe initial diagram showing new/half/full moon goes off my screen, presumably because I'm at 150% desktop zoom and it possibly somehow gets confused by that? Also the feedback about the wrong side being illuminated.
