This actually happened to me after connecting to wi-fi but there is a workaround that I found:
Convert your book to .azw3 in Calibre
Instead of sending it to the device in Calibre, locate the azw3 file (Right click -> Open book folder).
Copy the file to your Kindle, but not to the "documents" folder (where Calibre usually puts it) but rather into Downloads->Items
This folder is where books go when you buy them from Amazon or receive them after using the Send to Kindle feature. I have only tried this with azw3 so far but it might also work with .mobi format.
I'm guessing the GP means that there will hopefully be an increased interest for alternatives to planes that one can take when there are air travel crises like this.
The article uses "new field" as a relative term -- a field that the researcher is not an expert in.
> A question [BD14] had to address in this connection is: what constitutes a
brand-new direction? Again MathSciNet guides the answer. For each pair of the 73
Mathematics Subject Classification numbers, the authors worked out the likelihood
that a paper in one area is referred to by a paper in another area. Thus, for instance, they see that 35 (Partial Differential Equations) is closest to 58 (Global Analysis)and 76 (Fluid Mechanics) but furthest from 08 (General Algebraic Systems) and 19 (K-theory). Borjas and Doran deem a topic brand-new if it is not among the 15 closest to the researcher’s original area. This is a conservative choice and probably underestimates the cognitive mobility
I also suffered from this issue for a while but then discovered "Unhook" browser extension, which in addition to many other amazing features (e.g. hide recommended videos/comments) has a feature to hide irrelevant search results. With the feature on I get an endless list of matching results and no junk.
