One should not miss Figure 1 of the arXiv preprint, which is, alas, absent from the final PRL.

It is among the rarest journal-article figures in physics. If I'd been asked to referee the paper, I'd have campaigned hard to keep it in.
- modzu 6y agothank you for this, i laughed out loud
- themodelplumber 6y agoFascinating. And kind of funny. I wonder, are there any YouTubers who walk through the math in papers like this? Asking because it seems really interesting and sometimes it's fun to learn bits here and there from applied math rather than always working up from the fundamentals.
- canjobear 6y agoPBS SpaceTime
- me_me_me 6y agoHalf of their stuff goes over my head. And I have to watch videos multiple times, but very interesting channel indeed.
- shifto 6y agoThis channel makes me feel dumb. It all goes over my head but he is explaining it like he is teaching a group of 10 year olds.
- me_me_me 6y agoIts good to remind yourself you are not the smartest person in the room.
- meowface 6y agoI'm absolutely abysmal at even basic math (arithmetic, algebra), let alone anything involved in theoretical physics, but I've never had any issue understanding that channel because as far as I can remember, they don't actually bring up any equations or other math. Maybe there are some math-y episodes I haven't seen, dunno, but I was under the impression it was targeted at laymen and designed to be as accessible as possible, like many PBS things. I've learned a ton from it and have never felt they went too advanced for regular people. Now, minutephysics or 3blue1brown? Love their videos, but most of them go way over my head. I find PBS Space Time exponentially easier to follow than minutephysics. Just saying this in case anyone anyone were to otherwise be discouraged from checking it out.
- wrnr 6y agoThe channel I find most accessible for laymen, that goes into the maths, is DrAPhysics[1]. It's done by some random English radio jockey with a background in Physics. Nothing on the cutting edge, but I like his simple presentation of manipulating symbols on paper by hand. If you want visuals there is this[2].

- DarmokJalad1701 6y agoThis kind of makes me want to do Youtube videos about stuff that I know. Procrastination is a b*tch though ...
- 127 6y agoAnton Petrov https://www.youtube.com/user/whatdamath https://www.youtube.com/user/whatdamath goes through astrophysics papers quite often. The channel is pretty cool if you like space in general.

- NamTaf 6y agoI love it. I found it actually useful to get a physical scale understanding of the size of one.
- QuesnayJr 6y agoIt was the very first thing I wondered when I read the title.
- slaymaker1907 6y agoMy guess is that they wanted it removed since it is more useful communicating outside the field and that printing out that figure would take a lot of ink. Even if the journal doesn’t do much actual printing, I know many researchers that prefer to print out articles before reading them.
- m_mueller 6y agocould have replaced it with a white filled circle though, or a grayscale version that uses much less ink.
- jl6 6y agoWas it removed because “exact scale” only makes sense if the article is printed on a specific paper size, which isn’t specified?
- markonen 6y agoObjects in a PDF are specified in points, which is a physical measure (1/72 of an inch, or 0.3528 mm).
- yencabulator 6y agoAnd printer drivers often have a "fit on page" feature enabled. ... not that A4 vs US letter would be a huge percentual difference, for this image.
- ziotom78 6y agoI too rushed to check if the figure survived to the referees' comments. Alas, what a pity!
- cercatrova 6y ago> The associated DM halo however extends to the stripping radius ∼8AU, this would imply a DM halo which extends roughly the distance from Earth to Saturn (both in real life and relative to the image). Well, how can the article authors know we're reading this on Earth and not some other planet?
