The Kardashian Index (K-Index), named after Kim Kardashian, is a satirical measure of the discrepancy between a scientist's social media profile and publication record. Proposed by Neil Hall in 2014, the measure compares the number of followers a research scientist has on Twitter to the number of citations they have for their peer-reviewed work.

- G gauge track has a spacing of 45 mm between the railheads (tracks) (c.f. 44.45 mm for 1 gauge , but that does not determine the scale to which the models are built because, to maintain a constant track width when real-life counterparts have a variety of railroad gauges, the scale has to vary. The most common full-scale practice uses a spacing of 4...
