Anyone Buying Lead? (For Room Temperature Superconductors)

  It's crazy all the labs are in China and India.  Maybe that's where the world is heading.  

I'll look at the results closer but china and India are notorious for fake data in the scientific circles. Also, arxiv is not peer reviewed so I'd wait for something like nature (or other lesser known publications like acta met, j phys, etc.)

There was also a tweet (that I can't currently find) from UMD QMC - one of the top centers when it comes to superconductors and quantum in general - that the paper was basically sloppy and analysis lacking.

Yea for sure.  I think most physicists agree with that.  It’s looking more likely than not that this is not a room temperature superconductor, but I think it seems like scientists are optimistic that this paper is not junk and pushes the frontier closer towards that goal.

You and I are interpreting the results differently. My interpretation is that LK 99 is not a superconductor at any temperature so the only frontier that's being pushed is the one that says don't do more testing with LK 99.

You are right it's looking more like a dud based on what has come out the last couple of days but there have been some replications that demonstrate partial success, Superconducting at 110K and ambient pressure. See Wikipedia's list of replications.

Well folks, if it looks, sounds and acts like a dud, it probably is.

Modern academia is probably one of the worst things to have happened to science. It is today nothing but a D measuring contest on who is more 'intellectual' than the other. This being from South Korea, from day 1 have said to people who asked me about LK-99 that this is bearing a nasty resemblance to the Hwang Scandal. Innovations as essential as a superconductor don't just pop up one day all of a sudden, takes decades of trial and error.
