Why do people keep writing about the imaginary compound Cr2Gr2Te6? (righto.com) I was reading the latest issue of the journal Science, and a paper mentioned the compound Cr2Gr2Te6. For a moment, I thought my knowledge of the periodic table was slipping, since I couldn’t remember the element Gr. It turns out that Gr was supposed to be Ge, germanium, but that raises two issues. First, shouldn’t the peer reviewers and proofreaders at a top journal catch this error? But more curiously, it appears that this formula is a mistake that has been copied around several times.

Apparent magnitude (Wikipedia) Apparent magnitude (m) is a measure of the brightness of a star or other astronomical object. An object’s apparent magnitude depends on its intrinsic luminosity, its distance, and any extinction of the object’s light caused by interstellar dust along the line of sight to the observer.

Reticulum (Wikipedia) Reticulum is a small, faint constellation in the southern sky. Its name is Latin for a small net, or reticle—a net of crosshairs at the focus of a telescope eyepiece that is used to measure star positions. The constellation is best viewed between October and December, and save for one main star visible in ideal conditions, cannot be seen from north of the 30th parallel north.
