Grilling with Lava [New York Times]
This July Fourth, we offer an intense, but minimalist way to grill steak. It requires 800 pounds of Wisconsin basaltic gravel heated to 2,000 degrees. New York Times food writers have advocated cooking directly on hot coals this Fourth of July, but the truly adventurous may want to consider another approach: lava-grilled steak. The Syracuse University professors Bob Wysocki and Jeff Karson, the leaders of this minimalist technique, say the key is to start with thin-cut steaks, the more marbled the better. You then find the nearest retrofitted bronze furnace. (Very likely, that is the one the professors have built for themselves in Syracuse as part of the university’s Lava Project. When not cooking dinner with it, Mr. Wysocki, an artist, and Mr. Karson, a geologist, create lava for scientific research and sculptures.)[more inside]

Cheetahs’ Secret Weapon: A Tight Turning Radius [New York Times]
"Anyone who has watched a cheetah run down an antelope knows that these cats are impressively fast. But it turns out that speed is not the secret to their prodigious hunting skills: a novel study of how cheetahs chase prey in the wild shows that it is their agility — their skill at leaping sideways, changing directions abruptly and slowing down quickly — that gives those antelope such bad odds."
Why You Won’t Be the Person You Expect to Be (NYT): "When we remember our past selves, they seem quite different. We know how much our personalities and tastes have changed over the years. But when we look ahead, somehow we expect ourselves to stay the same... They called this phenomenon the “end of history illusion,” in which people tend to “underestimate how much they will change in the future.”" (via exp.lore) [more inside]
"Older parenthood will upend American society." "Is waiting to have kids a big mistake?" "Why do women believe they can delay children for so long?" "Older men are more likely than young ones to father a child who develops autism or schizophrenia, because of random mutations that become more numerous with advancing paternal age."
Last year, The Cooper Union For The Advancement Of Science And Art publicly admitted it was in dire financial straits and raised the idea of charging tuition for the first time in 110 years. The students responded in an appropriate manner. But now as the specter of tuition becomes closer to reality the students took a more drastic option: Since Monday, eleven undergraduate students have expertly barricaded themselves inside the top floor of the New York college. They talk about what they want. They even get pizza. [more inside]

Double Full Full Full, annotated (NYT video, reg REq'd) U.S. Olympic Team aerial skier Ryan St. Onge and a science reporter describe via video the physics going on as he executes a triple backflip with four twists. Also, the snowboard halfpipe. (Don't ask me why a triple backflip with four twists is called a "double full full full")

NYT Guesstimation Quiz. Enrico Fermi estimated the yield of the Trinity A-bomb test by dropping some shredded paper. He also asked his students to estimate unusual quantities like the number of piano tuners in Chicago - to show that just about anything can be estimated without detailed knowledge.
