Damn, it wasn't so easy to find the article, because TFA doesn't explicitly provide author names, even. But the link in the image title led to Fein et al. (2019).[0] So what I'm curious about is how far apart those "Two Places at Once" are. And if I'm understanding Fig. 2 correctly, it's large. That is ... > Fig. 2 | interference data. a, Counts as a function of the transverse position of the third grating with a sine-fit (solid black line) yielding a visibility of 25 ± 3%. The optical grating power was 1.2 W for this single scan. Counts are dark-rate-corrected and normalized to the control measurements. ... with peaks at ~200 nm, ~430 nm, ~680 nm and ~900 nm. But a 25 kDa molecule is only ~4 nm in diameter.[1] That's amazing! 0) https://sci-hub.tw/http://dx.doi.org/10.1038/s41567-019-0663-9 https://sci-hub.tw/http://dx.doi.org/10.1038/s41567-019-0663... 1) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3055910/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3055910/

Thank you! Rant: Not linking to the source article is a crime conmited by many outlets trying to report on science. I do not understand that practice. It is even worse when the researcher's institution does this in a public press release (MIT is consistently guilty of this). Are these people afraid that their watered down "explanations" are so wromg that even a cursory glance over the paper will show this? Some news sites such as Ars Technica provide the links. They even have agreements with major publishers that allow them to bypass paywalls and provide their readers with links to the the published full text as well.

  There's a dated document that leaked at the start of the decade called The AOL Way that sheds a lot of light on these tactics - https://www.slideshare.net/cartercole/the-aol-way-leaked-plan https://www.slideshare.net/cartercole/the-aol-way-leaked-pla... External links are used for SEO and generally reserved for partner-websites or their own properties to recirculate traffic. Here we have an article reposted from space.com to scientificamerican.com that only links to nature.com and livescience.com. Future US owns space.com + livescience.com, and Springer Nature owns scientificamerican.com + nature.com.

    It doesn't need to be a link. A citation at the bottom of the article would suffice.

    Hey, this is my field. It's not as easy as you've laid it out. A lot of SEO marketers try to get links into articles. This is part of what they do. Many of them are legit. Enough are not legit. This causes links to get pointed to shady websites. It also happens that legit websites get taken over and re-built as shady websites. This has gotten to the point where many newsmedia organizations or publishers have set blanket policies that NO ONE is to be linked to, or at the least no one receive will receive do-follow link.

Dunno if it was a link when you looked, but "Nature Physics" in the third paragraph links directly to the paper and bypasses the Nature paywall with some sort of referer link. [0]: https://www.nature.com/articles/s41567-019-0663-9 https://www.nature.com/articles/s41567-019-0663-9

  Thanks. > Now, in a paper published Sept. 23 in the journal Nature Physics, an international team of researchers has caused molecule made up of up to 2,000 atoms to occupy two places at the same time. That wasn't there when I read it.

I was hoping that someone would review my interpretation of the result. Because I am not a physicist, so most of their discussion is over my head. What I pointed to tells me that the spacing of interference fringes for a ~4 nm object was ~230 nm. But does that mean that the object's wave function leads to probabilities spread over hundreds of nanometers? Or does the fringe spacing merely result from small angular displacements over a long distance?
