"Children are required to be in school, where their freedom is greatly restricted, far more than most adults would tolerate in their workplaces. In recent decades we’ve been compelling them to spend ever more time in this kind of setting, and there’s strong evidence that this is causing psychological damage to many of them. And as scientists have investigated how children naturally learn, they’ve realized that kids do so most deeply and fully, and with greatest enthusiasm, in conditions that are almost opposite to those of school….
Most people assume that the basic design of today’s schools emerged from scientific evidence about how children learn. But nothing could be further from the truth.
Schools as we know them today are a product of history, not research.
Research has shown that people of all ages learn best when they are self-motivated, pursuing answers to questions that reflect their personal interests and achieving goals that they’ve set for themselves. Under such conditions, learning is usually joyful.
The evidence for all of this is obvious to anyone who’s watched a child grow from infancy to school age. Through their own efforts, children figure out how to walk, run, jump, and climb. They learn from scratch their native language, and with that, they learn to assert their will, argue, amuse, annoy, befriend, charm, and ask questions.
They do all of this before anyone, in any systematic way, tries to teach them anything.
This amazing drive and capacity to learn does not turn itself off when children reach five or six. But we turn it off with our coercive system of schooling.”
Gamma-ray bursts (GRBs) are flashes of gamma rays associated with extremely energetic explosions that have been observed in distant galaxies. They are the brightest electromagnetic events known to occur in the universe. Bursts can last from ten milliseconds to several minutes. The initial burst is usually followed by a longer-lived “afterglow” emitted at longer wavelengths (X-ray, ultraviolet, optical, infrared, microwave and radio).
Most observed GRBs are believed to consist of a narrow beam of intense radiation released during a supernova or hypernova as a rapidly rotating, high-mass star collapses to form a neutron star, quark star, or black hole. A subclass of GRBs (the “short” bursts) appear to originate from a different process - this may be due to the merger of binaryneutron stars. The cause of the precursor burst observed in some of these short events may be due to the development of a resonance between the crust and core of such stars as a result of the massive tidal forces experienced in the seconds leading up to their collision, causing the entire crust of the star to shatter.
Gamma-ray bursts are thought to be highly focused explosions, with most of the explosion energy collimated into a narrow jet traveling at speeds exceeding 99.995% of the speed of light. The approximate angular width of the jet (that is, the degree of spread of the beam) can be estimated directly by observing the achromatic “jet breaks” in afterglow light curves: a time after which the slowly decaying afterglow begins to fade rapidly as the jet slows and can no longer beam its radiation as effectively

wow. I just cant get over how ppl only give him CHANGE! he should be on a talent show
no drummer has shit on this dude
did nOT think this was going to be as incredible as it was when i started this
That has to be the dopesters shit I’ve heard in a minute
