Editorialised title - actual title is "The Search for a More Perfect Kilogram". Wired should use your title though ("Everything is Getting Heavier") - it's a catchy title for an interesting article. Also the picture half-way down is totally a TARDIS.
- ChuckMcM 15y agoThe article did state that the 'secondary' versions of the kilogram were getting lighter with respect to the Grand K and it was up to 500 mG which is quite significant. It would be interesting to know what is the source of that error (I didn't find the speculation of out gassing to be particularly compelling, but I didn't recall them mentioning how the companion standards were built).
- caf 15y agoIt's not "five hundred milligrams" (500mg), it's "five-hundredths of a milligram" (0.05mg, or 50μg).
