Probable observation of the Josephson superconducting tunneling effect Updated 2025-07-16

 View more

Paper by Philip W. Anderson and John M. Rowell that first (?) experimentally observed the Josephson effect.

Paywalled by the American Physical Society as of 2023 at: journals.aps.org/prl/abstract/10.1103/PhysRevLett.10.230

DOI: doi.org/10.1103/PhysRevLett.10.230

TODO understand the graphs in detail.

They used tin-oxide-lead tunnel at 1.5 K. TODO oxide of what? Why two different metals? They say that both films are 200 nm thick, so maybe it is:

   -----+------+------+-----
...  Sn | SnO2 | PbO2 | Pb  ...
   -----+------+------------
          100nm 100nm

A reconstruction of their circuit in Ciro's ASCII art circuit diagram notation TODO:

DC---R_10---X---G

There are not details of the physical construction of course. Reproducibility lol.

. TODO what do the dotted lines mean?

This actually happens in spring. But because they are so euphemistic winter had to be removed from the calendar, it gets shifted a left.

Stack Overflow should pay its top contributors Updated 2025-07-16

One may dream.

If they belive that their reputation is a representative meaningful metric, then it should be fine!

And if not, then they should fix it.

Notably, more people would try to "game" the system by quickly answering lots of small impact answers which could tilt things off a bit. Not to mention straight out fraud.

So basically less money into developers doing useless new features for the website, and more money back into meaningful contributors.

How about 2k USD / month for the number one contributor of the year, going linearly down to 0 for the 200th? This would be 100k USD / month, so about 12 developers.

How to cite a book on Wikipedia Updated 2025-07-16

 View more

To avoid duplication when citing multiple pages: Section "How to use a single source multiple times in a Wikipedia article?"

A good big sample definition:

<ref name="googleStory">{{cite book |last1=Vise |first1=David |author-link1=David A. Vise |last2=Malseed |first2=Mark |author-link2=Mark Malseed |title=The Google Story |date=2008 |publisher=Delacorte Press |url=https://archive.org/details/isbn_9780385342728}}</ref>

There is also title-link to link to a wiki page. But it is incompatible with url= for Internet Archive Open Library links which is a shame.

Cool tool that allows you to graphically visualize page view counts of specific pages. It offers somewhat similar insights to Google Trends.

Homepage: pageviews.wmcloud.org/

Documentation: meta.wikimedia.org/wiki/Pageviews_Analysis#Massviews

The homepage shows views of selected pages, e.g. when Google had their 25th birthday: pageviews.wmcloud.org/?project=en.wikipedia.org&platform=all-access&agent=user&redirects=0&start=2023-09-11&end=2023-10-01&pages=Cat|Dog|Larry_Page Larry Page briefly beat "Cat" and "Dog".
