Better Sleep, Better Learning? Obstructive sleep apnea can reduce a child’s IQ by 10 points

From Science Life Blog at the University of Chicago:

Pediatric obstructive sleep apnea, or OSA, can have long-term, detrimental effects on a child’s cardiovascular and respiratory health. But it can also create neurocognitive effects, such as a reduced ability to learn and retain information.

OSA can reduce a child’s IQ by as many as 10 points, while treatment in children with OSA can improve grades.

Current school system is failing boys - how to re-engage them in learning - TED video

At TEDxPSU, Ali Carr-Chellman pinpoints 3 reasons boys are tuning out of school in droves, and lays out her bold plan to re-engage them: bringing their culture into the classroom, with new rules that let boys be boys. The first part of the talk points to some eye-opening facts about how the current school system is failing boys.

The 10-year rule: you must persevere with learning and practising for 10 years before making breakthrough

From The Lancet:

Hard work is required: “Genius is one per cent inspiration, ninety-nine per cent perspiration” - Thomas Edison

Late in life, Charles Darwin made the same point in a letter to his son: “I have been speculating last night what makes a man a discoverer of undiscovered things, and a most perplexing problem it is.—Many men who are very clever,—much cleverer than the discoverers—never originate anything. As far as I can conjecture, the art consists in habitually searching for causes or meaning of everything which occurs.” Darwin was a relentless student of nature from 1828 until the few weeks in late 1838 when he suddenly perceived the mechanism of evolution by natural selection.

There can be no doubt that geniuses have worked habitually and continually. Darwin produced 160 published papers, in addition to celebrated books and a vast correspondence. Albert Einstein had 240 publications, Sigmund Freud 330, Henri Poincaré 500 papers and 30 books; Edison was the owner of 1093 patents, lodging an average of one patent every 2 weeks of his adult life. In the arts, J S Bach on average composed 20 pages of finished music per day, while Pablo Picasso created more than 20,000 works.

Experience is essential: “Where observation is concerned, chance favours only the prepared mind” - Louis Pasteur

The 10-year rule states that a person must persevere with learning and practising a craft or discipline for about 10 years before he or she can make a breakthrough. The initial scientific evidence for the rule came from studies in the 1960s and 1970s of chess-players, who take 10 years and more to become masters of the game. Then it was found to apply to Olympic swimmers and concert pianists.

Hardly any genius in history—not even Leonardo da Vinci—seems to have short-cut the long and gradual path to creative breakthroughs.

@equijada: the ability to infer disparate ideas into one is the 1%. The rest is just salty water. 10-yrs, 10,000 hrs -> playing w/ observations
