Comment Re:RottenTomatoes is Horrible, Agreed (Score 1) 395

Most of my favorite movies have low scores, most movies I consider epic and mind blowing have mediocre scores. That website is horribly wrong about movies 99% of the time....

I take you at your word oh AC. In which case Rotten Tomatoes is functioning perfectly even for you! Just apply your own preference metric to the site. If low scores=great to you then it is telling you exactly what you want to know. Go out and see the low scoring movies! Problem solved!

Indeed. Also this jerk has more than a touch of RIAA/MPAA disease - the belief that society owes them arbitrarily large amounts of money regardless of their product, demand, or business model. $850 million makes him cry? It should of been a billion, no make that two billion! How dare people publicly express a negative opinion about my movie! There shouldn't be any source of negative reviews! Only positive reviews should ever be published! It is so unfair to me!

Comment But Not the Fastest Star Known! (Score 2) 124

That would be S0–2, a star orbiting Sagittarius A* - the gigantic black hole at the Milky Way's center.

S0-2 has a longer orbit than 47 Tucanae X9, because it is highly elliptical, but at closest approach to Sagittarius A* is reaches 5000 km/sec. The speed of 47 Tucanae X9 is 3500 km/sec.

Comment Otherwise Known As A Jökulhlaup (Score 4, Interesting) 136

Glacier outburst floods are known as "jökulhlaups" in geology, an Icelandic word since it has been the scene of many historic floods of this type.

In 1755 a jökulhlaup from the Katla volcano had a peak flow of up to 400,000 cubic meters/second, about 20 times the flow rate of the Mississippi River, or twice that of the Amazon, making it briefly the largest river in the world.

But that's not the only destructive aspect of Iceland's volcanoes. In 1783 the eruption of the Laki volcano released 14 cubic kilometers of basalt and 1 cubic kilometer of airborne ash. It killed 25% of Iceland's population through poison gas: 500 million tons of hydrogen fluoride and sulfur dioxide were released poisoning the population and the livestock. The fatalities were both from direct poisoning (mostly from the hydrogen fluoride) and later starvation since most of the livestock was killed. The toxic cloud affected much of Europe as well, though not as severely. This eruption also created a three-year long period of unseasonable cold in the northern hemisphere leading to famine killing thousands, and possibly contributing to the French Revolution.

Very true.

This is only one example of a long series of discoveries over the last 40 years. An extensive system of earth works, causeways, and canals have been found along the Xingu river (an Amazon tributary). Large sections of jungle have turned out to be fruit tree orchards that over-grew with forest (which would have happened quite quickly once left untended). The entire Amazonian basin itself was virtually unknown to European civilization until the 20th Century - for most of that time it was outside of the control of colonial and later Brazilian government, being instead controlled by societies of Indians and escaped slaves. Societies of many tens of thousands of Indians, like the Yanomamo, only started being studied by westerners starting in the 1950s and to this day live in areas outside of state administrative control. Discoveries like this are being made all over the Amazonian basin, now that westerners are actually examining it.

To die, to sleep--
No more--and by a sleep to say we end
The heartache, and the thousand natural shocks
That flesh is heir to. 'Tis a consummation
Devoutly to be wished. To die, to sleep--
To sleep--perchance to dream: ay, there's the rub,
For in that sleep of death what dreams may come
When we have shuffled off this mortal coil,
Must give us pause.

Comment The Is No One Purpose for Sleep (Score 1) 145

The need for "sleep" (regular periods of markedly reduced activity, distinct from mere rest) is virtually universal across the vertebrate sub-phylum at least, with a last common ancestor 500 million years ago, found in every family (though not necessarily obviously so in every species).

This extraordinary common pattern in creatures with radically different environments and life habits, persisting over such a vast stretch of evolutionary time, alone suggests there is not "one reason" for it, and indeed a lot of research has uncovered many necessary processes associated with sleep, which go hay-wire at different rates when sleep is denied. In fact going without sleep is lethal, usually killing animals faster than starvation.

Evolutionary biology offers a coherent explanation for all of these facts. Periods of inactivity to conserve energy and reduce exposure to predators is an evolutionary advantage, so a branch of evolutionary descent would tend to develop such a pattern if one did not already exist. Once a regular period of reduced activity exists biological processes that are more efficient or effective during periods of inactivity would tend to migrate in timing to coincide with it. Thus many biological processes, related or not, would in time become associated with this "sleep" period in a common pattern of convergent evolution, and the organism would become dependent on sleep periods for many unrelated biological reasons.

For what I hope are obvious reasons, Microsoft cares the most about those users!

And yet, only half of all employees work for large enterprises (according to the Census Bureau), and just about every employee, and lots and lots of non-employees have their own computers at home. So those users, which even you - a self-verified Microsoft pitch-man (to use a polite term) - readily admit are less "cared" about by Microsoft are the large majority of their total user base, and the source of the large majority of its revenues.

Saurischians are dinosaurs, dinosaurs are saurischians. Birds are saurischians. Birds are dinosaurs. Since the publication of The Origin of Species, and the flurry of evolutionary classification that took off after it, birds have been recognized as some kind of Archosaur or another. Birds have always been known to have been dinosaurs.

You are certainly correct that the identification of birds with dinosaurs was proposed quite early, but it is going a bit too far to say that was generally "known" to be the case. The "Are Bird's Dinosaurs?" debate, was absolutely a topic of argument for a century and a half, but is really two overlapping debates. The first is the actual descent of birds from fossilized (proposed) ancestors, and the second is a fundamental one for evolutionary classification, how should you group species (i.e. what is a taxon)?

Linnaean taxonomy was based on grouping species by common characteristics, but this created lots of paraphyletic and polyphyletic taxons. A paraphyletic taxon includes an ancestor, but only some of its descendants as member; a polyphyletic taxon excludes the common ancestor of the members and usually some of the other descendants as well (convergent evolution is a common reason for this).

Cladistics, the use of statistical grouping methods (aided by computers), clarified things considerably starting in the 1960s, and then genetic analysis put it into hyperdrive, proving the fundamental correctness of the cladistic approach, and giving it an unambiguous standard of validity. Modern groupings invariably strive to be monophyletic.

Cladisitics actually helped clarify the interpretation of the fossil record for birds so in the 1980s biology came to recognize that a consistent method of classification, combined with a better interpretation of fossil evidence required birds to be classified as a type of dinosaur.

It really is more than a matter of changing labels. This did create a change in understanding about how to think about dinosaurs based on the surviving branch of the taxon, and about the origin and nature of birds.

Multiples of 3 are just so much more useful in everyday life than multiples of 10. I used the base 12 pica/point system in printing for many years, and always admired how trivially easy it was to calculate layout proportions. The human attention is drawn strongly to things in threes: three panels, three points in an argument, three parts to a story, and many others.

More than just the magic of 3. Since 12 has the three smallest (non-trivial) integer divisors, and four of the five smallest, it is simple to do many proportional (ratio) calculations and measurements. 10 only has two (non-trivial) integer divisors.

This extended to adding 5 and 6 as divisors gives the 360 degree division of the circle, invented by the Sumerians and adopted universally around the Old World (along with their division of the day into 12, then 24 hours, for similar reasons). Utility is proven by use.
