Internet Not Really Dangerous For Kids After All 445

Thomas M Hughes writes "We're all familiar with the claim that it's horribly dangerous to allow our children on to the Internet. It's long been believed that the moment a child logs on to the Internet, he will experience a flood of inappropriate sexual advances. Turns out this isn't an accurate representation of reality at all. A high-profile task force representing 49 state attorneys general was organized to find a solution to the problem of online sexual solicitation. But instead the panel has issued a report (due to be released tomorrow) claiming that 'Social networks are very much like real-world communities that are comprised mostly of good people who are there for the right reasons.' The report concluded that 'the problem of child-on-child bullying, both online and offline, poses a far more serious challenge than the sexual solicitation of minors by adults.' Turns out the danger to our children was all just media hype and parental anxiety." Those who have aggressively pushed the issue of the dangerous Internet, such as Connecticut's attorney general Richard Blumenthal, are less than happy with the report.

The reviewer is a moron. No only his euclidian distance formula is wrong (as in primary school wrong), but if he ever got past reading the first chapters of Wildberger's book, he should know that the whole idea is to get rid of cosines, sines and other trigonometric functions in algebra computations. Few people realize that the angle concept we use is axiomatic and ill-defined algebraically. The beauty of Wildberger's approach is to redefine a lot of algebraic formulas in the shape of quadrance and spread equivalent formulas that are much more precise, and easier to compute. The rest of the review was made on a mushroom-induced delirium
So the reviewer cheats by using cosines and sines in his example. Where did he get those values? From a table or calculator. Sines and cosines are computed by adding a (truncated) infinite series of numbers. You dont't have to do that using rational trigonometry, that's the wole point. It's like proposing going from New York to Boston without riding a car (by flying on a plane), and saying that it is ridiculous, because you like driving from New York to Boston just fine.
I remember an old southafrican (boer) joke.
