Re: 1825: "7 Eleven"

I'm still waiting for the Sidereal vs. Solar Day flamewar. C'mon, folks! OK, I'll bite. Solar time is time measured with respect to the Sun's apparent motion in the sky, while sidereal time is measured based on the apparent motion of the 'fixed' stars in the sky. Since planets orbit around the Sun,...

Re: Alternate clock

Had trouble working out where the quote in OP was from at first, so I decided to link it here. At any rate, almost everything mentioned in this thread has been proposed before (as far as I can tell only the 36+1/2 day month is a new one - what do you propose to do with leap years?). I'm surprised no...

Re: 1643: "Degrees"

Maybe we should have purely cardinal time (making today 2015:01:15:10:28:30), or purely ordinal time (31/29/11/16/02/2016). :D [1] Which, it occurs to me, fits the European system ("the sixteenth of February, 2016") rather than the USAnian ("February (the) sixteenth, 2016"). (Fo...

Re: 0657: "Movie Narrative Charts"

The ABC did a narrative chart today encompassing each of the Star Wars original and prequel trilogy movies. They're quite detailed, and one can see a noticeable increase in complexity for the prequels compared to the original movies.

Re: 1555: "Exoplanet Names 2"

Necroposting because IAU just posted their first batch of exoplanet names. Unfortunately, we lost Upsilon Andromedae b, c and d, as well as Epsilon Eridani b.

Re: 1516: "Win by Induction"

FWIW I think Q was perhaps a bit harsh. I think you may be right. @Arcorann - I was holding you to a very high standard. Please feel welcome to stay and discuss. Don't worry, I hold myself to a very high standard as well. I'd contribute further to the discussion, but quite frankly Qaanol has covere...

Re: 1516: "Win by Induction"

Revives argument in inflammatory and dismissive manner. I hope this can lay the argument to rest. In fairness though I did think that the argument was still going. I know that there were people who still seemed to have the wrong impression, at least. And I apologise if you found my remark inflammat...

Re: 1516: "Win by Induction"

I have no idea how people are still arguing whether there number of Pikachu is countably or uncountably infinite. I mean, it's easy to enumerate them with natural numbers, so I thought it was obvious that they are countable. As far as I can tell, the problem with the so-called "irrational Pikac...

Re: Finding astronomical distances in a geocentric system

The problem I have with your question is how to define "Earth-like planet" and "Human-like civilisation": an Earth-like planet could never be massive enough to satisfy your system, and a civilisation that developed on a more massive celestial body would hardly be Human-like... O...

Finding astronomical distances in a geocentric system

Consider a hypothetical system in which the local sun moves around an Earth-like planet with one moon also similar to ours. The planet takes a path around its galaxy comparable to our sun's path around the Milky Way. I'll leave the details of whether there are any other planets in the system unspeci...

Re: 1340: "Unique Date"

No-one's mentioned RFC 2550 yet? Guaranteed to work arbitrarily far into the future, and it's compatible with our current system. What could possibly go wrong?

Re: n sided polygon, n < 3

Just stopping by to point out that an n-gon with n=a/b (b does not divide a) has meaning if n>2, you just get a self-intersecting polygon - or rather, a star (e.g. 5/2 gives a pentagram). On the other hand, the sum of the angles of the star is actually 180(a-2b) degrees, so...

Re: 1275: "int(pi)"

I was also reminded of a problem set by Chris Maslanka in The Guardian . You have to make all the integers from 1 to 100 using five 5's The earlier form of this problem (going back to the late 19th century) uses four fours. The first printed occurrence of this activity is in "Mathematical Recr...
