Geology Makes You Time-Literate - Issue 64: The Unseen

As a geologist and professor I speak and write rather cavalierly about eras and eons. One of the courses I routinely teach is "History of Earth and Life," a survey of the 4.5-billion-year saga of the entire planet--in a 10-week trimester. But as a human, and more specifically as a daughter, mother, and widow, I struggle like everyone else to look Time honestly in the face. That is, I admit to some time hypocrisy. The now risible "Y2K" crisis that threatened to cripple global computer systems and the world economy at the turn of the millennium was caused by programmers in the 1960s and '70s who apparently didn't really think the year 2000 would ever arrive.
