Five Stories About Precocious Young Wizards

Imagine, if you will, a story featuring a wizard, sorcerer, or mage who is not an elderly greybeard or crone but rather a child or teen. Ide

...Okay, this is a lovely shout-out. And to be mentioned in the same neighborhood as both Ursula Le Guin and Terry Pratchett and @neil-gaiman is seriously something I have to take a breath to recover from.

...Okay, better now. :)

A remarkable new study on how whales behaved when attacked by humans in the 19th century has implications for the way they react to changes wreaked by humans in the 21st century. The paper, published by the Royal Society on Wednesday [17 March 2021], is authored by Hal Whitehead and Luke Rendell, pre-eminent scientists working with cetaceans, and Tim D Smith, a data scientist, and their research addresses an age-old question: if whales are so smart, why did they hang around to be killed? The answer? They didn’t. Using newly digitised logbooks detailing the hunting of sperm whales in the north Pacific, the authors discovered that within just a few years, the strike rate of the whalers’ harpoons fell by 58%. […] Before humans, orca were their only predators […]. It was a frighteningly rapid killing, and it accompanied other threats to the ironically named Pacific. From whaling and sealing stations to missionary bases, western culture was imported to an ocean that had remained largely untouched […].

Catching a sperm whale during the 19th century was much harder than even Moby Dick showed it to be. That’s because sperm whales weren’t just capable of learning the best ways to evade the whalers’ ships, they could quickly share this information with other whales, too, according to a study of whale-hunting records. […]

“At first, the whales reacted to the new threat of human hunters in exactly the same way as they would to the killer whale, which was their only predator at this time,” study lead author Hal Whitehead, a professor of biology at Dalhousie University in Nova Scotia, told Live Science. “[The sperm whales] all gathered together on the surface, put the baby in the middle, and tried to defend by biting or slapping their tails down. But when it comes to fending off Captain Ahab that’s the very worst thing they could do, they made themselves a very large target.”

The whales seem to have learned from their mistakes, and the ones that survived quickly adapted — instead of resorting to old tactics, the whalers wrote in their logbooks, the sperm whales instead chose new ones, swimming fast upwind away from the whalers’ wind-powered vessels. […]

The whales communicated with and learned from each other rapidly, and the lessons were soon integrated into their wider culture across the region, according to the researchers’ interpretation of the data.

“Each whale group that you meet at sea typically comprises two or three family units, and the units quite often split off and form other groups,” Whitehead said. “So, what we think happened is that one or two of the units that make up the group could have had encounters with humans before, and the ones who didn’t copied closely from their pals who had.“ 

Sperm whales are excellent intel sharers: Their highly observant, communicative nature, and the fact that each family unit only stays in larger groups for a few days at a time, means they can transmit information fast.

As studies show, that information could be news on new threats, new ways to hunt or new songs to sing.

One example of whales’ extraordinary information sharing abilities involves lobtail feeding, in which a humpback whale slaps its tail hard against the water’s surface, submerges to blow disorienting bubbles around its prey, and then scoops the prey up in its mouth. Researchers first observed this tactic being used by a single whale in Cape Cod, Massachusetts, in 1980, before it spread throughout the regional population in just 10 years.

Whale culture also extends far deeper than innovative ways to feed. “Sperm whales are divided into acoustic cultural climates,” Whitehead said. “They split themselves into large clans, each with distinctive patterns of sonar clicks, like a dialect, and they only form groups with members of the same clan.”

Different whale clans each have different ways of singing, moving, hunting and looking after their calves. These differences are profound enough to even give some clans a survival advantage during El Nino events, according to Whitehead. […]

In the 20th century, whales, especially the 13 species belonging to the category of ‘great whales’ — such as blue whales, sperm whales and humpback whales — found themselves pursued by steamships and grenade harpoons that they could not escape. These whales’ numbers plummeted and they soon faced extinction. […] [T]hey still face the growing destabilization of their habitats brought about by industrial fishing, noise pollution and climate change.

Someone pointed out to me awhile ago that in SYW… they need all sorts of special materials to do their spells, and then later they just need words. Does anyone remember the explanation for that shift? i’m looking back through DW because i figure that’s where it would be? Or maybe in HW or AWAb?
