I guess Randall is sad that people outside the band seem to have less interest in the eclipse, like shown in the previous comic, and that they might not wish to travel a few hours to see a once in a life time spectacle, or as he also feared in the last comic, try too late to get there and get stuck in the trafic jam outside the totality zone.

I'm pretty sure his point was actually that in the modern day eclipses are pretty well understood, easy enough to travel to, and provide very little actually unique circumstances, so in reality there is very little scientific value at all. Just a really cool thing to see

Yet still there are some aspects of eclipses such as shadow bands which are unexplained. There are some theories, but eclipses are rare enough, plus shadow bands don't occur with every one, so there is no definitive explanation yet.

The explanation of shadow bands on wikipedia seems pretty solid to me. Zmatt (talk) 11:51, 17 August 2017 (UTC)

To me the comic is poking fun at the idea the media (and by extension laypeople in general) perceive eclipses to be of great scientific importance and that scientists are excited about it for that reason. Note how his almost every utterance contains "science". Megan deftly deflects his attempts to put words in her mouth and remains resolute in her stance that eclipses are interesting to everyone on their face value but not necessarily more so to scientists that others. 108.162.216.160 19:35, 16 August 2017 (UTC)Pat

The explanation claims, "While some astronomers might be testing elaborate hypotheses during an eclipse, for other scientists (eg. organic chemists and herpetologists) it is just a once in a long time (maybe even once in a lifetime) event which is visually interesting". This is at odds with the existence of several citizen science projects encompassing not just astronomy but also atmospheric sciences and animal behaviour. 162.158.111.241 13:00, 17 August 2017 (UTC)

So there's a couple points here:

  • Public demonstration of previously performed science is not really the same thing as actual experimentation where the outcome is in doubt, the latter of which advances our understanding. So yes, you can show something to people who haven't observed it directly before, but then you're not using the word "science" in the same way as Megan.
  • There actually are new experiments being performed, not just old experiments with a new audience or improved equipment.
  • There is a tendency among non-scientists to underestimate the certainty of scientific or statistical results. Some examples are "you can't teach evolution as settled science because it's only a theory" and more recently "this poll only sampled a thousand adults, which is 0.03% of Americans, so it's meaningless because we have no idea what the other 99.97% think". So scientists are expected to keep verifying and re-verifying fairly basic results. D5xtgr (talk) 16:29, 21 August 2017 (UTC)
That last one is hilarious, for reasons I doubt you realize. Some of us here know how to get a proper population sample--and, well, with that poll? I don't even know where to start on the potential sources of error. 'Too small' should appear on the list several times, though, since a lot of the sources of error can be controlled for by simply adding to your sample. (Yes, yes, changing your sampling techniques will also do it, but it's just plain easier to add more people, so you start there.) This is actually part of why being able to replicate results matter--plus, the training in how to do it properly does give you a pretty good idea how to rig your poll to produce the desired results, and what to watch for when reading others' research. 108.162.237.130 21:39, 24 August 2017 (UTC)
Reasons you doubt I realise? What are you on about? The point is, the fraction of the population appearing in your sample doesn't need to be very large to have a margin of error below five percent. Margin of error for a representative sample of 1000 from an infinite population is 3.2 percent - the hard part is to get a representative sample of adults rather than a biased one. And then you go on about "that poll"... your meaning is very unclear. D5xtgr (talk) 23:17, 29 August 2017 (UTC)
