It's also commonly called "Microwave Background Radiation" because where the radiation peaks at 160.4 GHz is in the microwave range of the electromagnetic spectrum. --Dangerkeith3000 (talk) 18:02, 13 March 2013 (UTC)
- Error - Inverted graph!
Am I the only one who came here confused because the graph is wrong? The shape of the graph is clearly that of blackbody radiation - on a wavelength axis! However Randall titles the axis GHz (pointing right) which is the inverse of wavelength (of course on a wavelength axis, the curve should not extend down to zero). But look up the graph on Wikipedia, and notice that it's on a wavelength scale and looks exactly like this - even better, google "black body radiation" images, and notice how ~95% of them show the radiation on a wavelength scale for some reason. But scroll down, and eventually you'll see one on a frequency scale. It looks quite different! Also, the blackbody radiation is known for its rather sharp high frequency cutoff (or low wavelength), which Randall accidentally got inverted here, and placed at zero... It shows much more dramatically on frequency axis, which is why you can very clearly see that this graph is NOT a radiation graph on a frequency axis - it goes on to infinity. Anyway, sorry for the rant - but it's Science bitches, and axis' matter! Especially if you are going to invert one of them! - Richard 22.214.171.124 22:56, 28 June 2018 (UTC)
- Title Text Meaning
As can easily be seen from the page's history, Dgbrt and I have been locked in a minor edit war over the meaning of the title text. I claim that Randall is simply complimenting the readers who happen to know what the formula and curve mean. Dgbrt thinks otherwise; I will let him explain his interpretation.
Glad to oblige. I think we need to draw a distinction between what Randall means and what some people might like him to mean. Many people don't agree that the universe started with a Big Bang, whether because they're cosmologists who support an alternative scientific theory, or because they're young earth Creationists who hold that God created the universe about 6000 years ago, or because they're philosophers who hold it self-evident that something can't come out of nothing, or for whatever reason.
Now, I'm not going to say which of those (if any) I believe, because it really doesn't matter in this context - and neither is it important (in this context) what Quicksilver or Dgbrt believes. What we have to keep clear in our minds is that this site is about explaining the cartoons, not projecting particular philosophical standpoints onto Randall's mildly ambiguous phrasing. (When he wrote it, I doubt very much whether he realised he was writing ambiguously.)
The xkcd series, throughout its history, shows not only Randall's firm belief in the scientific method for establishing plausible explanations of the way the universe works, but also his antipathy towards historical explanations that seem to be at odds with observable evidence and even historical record. See #803 and #1255 for obvious examples.
Given Randall's known love of science and the absence of any firm clues that he was being heavily ironic and running massively against type, I think we have to conclude that he was either praising those who could identify the science he was talking about, or just possibly was trying to cause a Wikipedia search spike! --BinaryDigit (talk) 07:17, 8 April 2014 (UTC)
So no one's gotten the bonus points yet?! He was asking to identify the science in question. When he says "It works", I'm sure he was not meaning that blackbody radiation works. This graph was the key to one of the biggest leaps in human understanding.--ChrisfromHouston (talk) 06:23, 8 September 2014 (UTC)
