Teaching and learning from preschoolers
Eroding companionship can be seen in numerous odd and depressing facts of American life today. Men who watch television now spend seven hours in front of the TV for every hour they spend hanging out with somebody outside their home. The typical female pet owner spends more time actively engaged with her pet than she spends in face-to-face contact with friends of her own species. Since the early 2000s, the amount of time that Americans say they spend helping or caring for people outside their nuclear family has declined by more than a third.
"What garlic needs in order to sprout, is the memory of winter. That the spring eventually comes is not enough to make life emerge — a good long cold is crucial. This memory of winter is called “vernalization.” Apples and peach trees won’t flower or fruit without it . . . The remarkable thing about vernalization is that it means plants remember. The term undisputedly applies; plants use information stored about the past to make decisions for the future. This isn’t a singular example. Plants take note of the length of a day and the position of the sun. Cornish mallow . . . will turn its leaves hours before sunrise to face the horizon in exactly the direction it expects the sun to rise. The movement itself originates in the tissue at the base of its stalks, where the mallow will adjust the pressure of the water flowing through it to bend in the desired direction. Throughout the day, the amount and direction of sunlight the mallow experiences is encoded in the photoreceptors laid out across its leaves. It stores the information overnight, during which time it will use it to predict where and when the sun will rise the next day . . . Researchers have messed with the mallow by simulating a more “chaotic “sun,” switching the direction of its light source. The mallow learns the new location . . . Memory clearly has deep roots in biology. This makes sense; if the trajectory of all evolution is toward survival, then the ability to remember has a natural evolutionary advantage. It’s incredibly useful for staying alive."
