Top Answers to Our Previous Question (On a Time You Pointed Out a Silver Lining to Someone) - My 75-year-old relative was knocked down in her home by the exuberance of her young, large, black lab, Jett. She sustained several bruises, and her knee was wrenched. She couldn’t walk, but managed to get to her phone to call for help. Seeking a positive, I said, “The good was that you were home, and not on the street, when Jett knocked you down. You did not have to crawl outside in the cold to get help.” She chortled and said, “I never thought of it that way.” – Kat R.

The 19th-century mathematician and physicist Christian Doppler died on this day in 1853. Most everyone is at least vaguely familiar with his work, since the “Doppler effect,” or “shift,” is part of our popular lexicon. Doppler showed that the apparent frequency of a wave—of either sound or light—depends on how fast the wave’s source and its receiver are moving relative to each other. We experience this phenomenon when a fire engine, blaring its siren, approaches us from a distance and then passes by: the siren has a higher pitch when nearer (the distance between waves is shorter), and a lower pitch as the fire engine speeds away (the waves stretch out). The same principle operates in space with light, wrote Richard Lawn. “We have detected planets orbiting stars by [observing the wobble in the Doppler shift]( of their spectrum as orbiting planets tug their sun to and fro during their orbit.” Today’s newsletter was written by Brian Gallagher Thanks for reading.
