Talk:1517: Spectroscopy

Thanks, Kynde, for the nice explanation. 108.162.221.201 13:29, 27 April 2015 (UTC)

Your welcome, and Thanks. I think I was still working on it when you wrote this comment ;-).--Kynde (talk) 13:42, 27 April 2015 (UTC)

I was wondering how many people go to watch these two songs on YouTube today (and the next few days) solely because of Randall's comic. I have long time wondered about this. Now maybe a time to find out. Of course we never know in advance how many new hits the song he chooses received the days before. But now we have a chance of following it over the next few days. Of course the comic has been up several hours but it is still early across most of the US... Here are the counters for the two videos linked above in the comic as of right before this post was made: Breathe: 9.493.222 and This Kiss 4.079.410. Please feel free to add new counts a few times over the next week or so. :-) --Kynde (talk) 13:42, 27 April 2015 (UTC)

Links for your convenience: "Breathe", "This Kiss" and as control "Cry".

"Breathe" 9,493,334, "This Kiss" 4,079,458, "Cry" 3,182,592 108.162.221.201 13:54, 27 April 2015 (UTC)

Thanks. Here goes after 1 day and 2 hours:

9.500.026 (+6692/+,07%)

4.083.297 (+3839/+,09%)

3.184.334 (+1742/+,05%)

I'm nut sure we can learn anything from this yet...?--Kynde (talk) 13:55, 28 April 2015 (UTC)

Actually, if the star or region of space is anything similar to our own, O2 is definitively a sign of life. Not animal life, but at least plant life, to crack the O2 out of the CO2 with photosynthesis.Seebert (talk) 14:00, 27 April 2015 (UTC)

The explanation currently covers links that show that not all oxygen will be created because of life, and not all life (even 'as we know it') will necessarily require/produce a significant oxygen signal. But there seems to be a missing middle-bit in that oxygen initially seems to have been a smothering 'industrial pollutant' by early (oxygen splitting) life-forms until other life-forms developed the machinary to use this oxygen as part of their own energy mechanisms (creating the eventual two-way dynamic of CO₂ and O₂ production/usage between the major groups of life) and thus making the unstable free oxygen both an indicator of life and an indicator of the capability of life (by mainstream terrestrial standards of biology, of course). 141.101.98.186 18:06, 27 April 2015 (UTC)

I'm pretty sure the original lyric for "This Kiss" is "it's centripetal motion" (see: http://www.sweetslyrics.com/59372.Faith%20Hill%20-%20This%20Kiss.html). I assumed the joke Randall was making was that centrifugal really is a force, Mr. Bond, even if Faith Hill doesn't know about it. Djbrasier (talk) 00:25, 28 April 2015 (UTC)

I agree: I only recall hearing "centripetal motion", but Google tells me there are actually more hits for "centrifugal", and that there are some lyrics sites putting both phrases in the song. Mark Hurd (talk) 01:41, 28 April 2015 (UTC)

I think the song says "centrifical" which is not even a word, let alone a force, ficticious or not. Nonetheless, it seems to be a common misspelling since it has its own wiktionary entry (http://en.wiktionary.org/wiki/centrifical). 108.162.249.180 08:54, 28 April 2015 (UTC)

I agree that she doesn't sing centrifugal. I have changed the explain to say it is centripetal (I'm sure she is supposed to at least, maybe she doesn't know the word either ;-) But left in a comment on the fact that there are different versions on-line. But I'm sure that that is because people do not know the word centripetal and also that people who make lyrics pages cut and paste from each other. I have often seen the same mistake on several lyrics pages. --Kynde (talk) 13:50, 28 April 2015 (UTC)
