I know you love a 20-25 digit tracking number that isn’t separated by spaces. I know you love making me type all those numbers into a crappy and confusing website. It would be really awesome if you would just put a QR code on the receipt that my phone could automatically detect and track. It would be sweet if the app even enabled push notifications so I got a text when the package was delivered.
Petrichor (pronounced /ˈpɛtrɨkər/; from Greek petra “stone” + ichor the fluid that flows in the veins of the gods in Greek mythology) is the name of the scent of rain on dry earth.
The term was coined in 1964 by two Australian researchers, Bear and Thomas, for an article in the journal Nature. In the article, the authors describe how the smell derives from an oil exuded by certain plants during dry periods, whereupon it is absorbed by clay-based soils and rocks. During rain, the oil is released into the air along with another compound, geosmin, producing the distinctive scent. In a follow-up paper, Bear and Thomas (1965) showed that the oil retards seed germination and early plant growth.
