Limiting the Teaching of the Scientific Process In Ohio

careysub Re:And this is how we get to the more concrete har (512 comments)

...

So that's the real end goal - to get religion - or more correctly, Christianity, back into schools so everyone becomes a "good little Christian boy".

...

Or even more correctly Evangelical Fundamentalist Christianity into schools. The Fundamentalist bloc is a political powerful sect in the U.S., but fairly unimportant in world Christianity; but has managed to misappropriate the term "Christianity" to only apply to themselves in practice. We shouldn't propagate this erroneous usage.

Limiting the Teaching of the Scientific Process In Ohio

careysub Re:If you don't want science... (512 comments)

Name a couple. I don't believe you understand what the church considered blasphemy to be. As for "a lot of them pretended", you cannot read minds. Especially those in the past.

What we can say is that following the trials or Giordano Bruno (executed) and Galileo (imprisoned for life, forced to recant) the Counter-Reformation shut down science where ever it held sway. Cremonini refused to look through Galieo's telescope, so afraid was he of being tainted by accusations of heresy. Copernicus's books were banned, until the 19th century. Cardano was prosecuted for heresy.

During the Age of Enlightenment that lands that languished under the Inquisition produced no important scientists. They didn't have to kill anyone else, they simply shut down critical thinking.

Limiting the Teaching of the Scientific Process In Ohio

careysub Re:just because the dept of ed.... (512 comments)

most of thethey do is disburse funds from the fed to the states

and this is the exact problem I have with the dept of ed. People in ny shouldnt be paying for students in cali, and people in north dakota should not be paying for students in fla. Keep the money local, and get rid of the overhead.

The portion of the Dept of Education you are complaining about, the appropriations part, comes to 65 billion dollars a year, out of total U.S. education spending of about 850 billion a year, so it is a grand total of 7.5% of that; the vast majority of U.S. education spending is already local -- exactly what you want. Happy?

And people in New York are not paying for students in California. The people in the wealthy states are, by and large, helping to educate people in poorer states, who otherwise have fewer resources with which to educate their poorer citizens (local funding has a devastating effect on education in poor counties). And what is wrong with the wealthy helping the poor?

Remember how the Constitution starts?

"We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America."

This is part of that vision thing: forming a more perfect Union by promoting the general welfare of the nation.

careysub Re:The US slides back to the caves (512 comments)

To be fair, Europe is a continent while the United States is a country.

Let me correct that for you: Europeans like to imagine that Europe is a continent, since Eurocentric thinking is endemic to Europeans (perhaps even more than the citizens of the United States are subject to USA-centric thinking). But Europe is actually a peninsula of the Eurasian continent, with adjacent regions, and comprises only 20% of the continent, and only 15% of its population.

The United States is 40% of the North American continent, and 60% of its population, so the U.S. comes much closer to "being a continent" than does Europe.

How the Ancient Egyptians (Should Have) Built the Pyramids

careysub Re:Slave labor is still the best explanation (198 comments)

...The line between "peasant" and "slave" in ancient societies is a vague one.

How the Ancient Egyptians (Should Have) Built the Pyramids

careysub Re:How did they build the pyramids (198 comments)

Yeah, I mean Herodotus is biased, but his isn't the only account that suggests that.

It isn't that Herodotus was biased, it is that he really did not know anything at all about Khufu, who had lived 2000 years earlier. Herodotus was simply passing on the sorts of tales that travelers hear about events that occurred thousands of years earlier in a culture where historical scholarship as we think of it was unknown.

How the Ancient Egyptians (Should Have) Built the Pyramids

careysub Re:They made the blocks into wheels (198 comments)

Did you read this article you linked to? It refutes this theory:

"However, even though this method is feasible and workable, it is unlikely that the GP's builders used it. The segments used by Bush had holes drilled into them to accommodate ropes which held the segments onto the block, yet none of the ancient segments found have such holes in them. How these alternative proposals fail is most clearly seen by considering the extreme case. Neither theory accounts for the movement of the fifty-ton granite slabs used in constructing the internal chambers of the GP. Considering the immense size of these monoliths, the flexible pole method would be rendered even more awkward. Forward motion would be extremely tedious--assuming that these monoliths could even be lifted by this method. Bush's idea would also be problematic. The dimensions of these slabs are not uniform, so each slab would have needed specialized circle segments. The largest monolith is about 27' x 4' x 8' at its ends.

The key failing of the cradle and the (actually extremely similar) pole theory is that it does not explain how they moved the far larger slabs that were not square blocks.

Also we have actual evidence of their methods - dragging on sledges. We have sledges, sledge tracks, and pictures of giant statues being dragged on sledges. They took the time to draw us a diagram, and people still look for other answers.

How the Ancient Egyptians (Should Have) Built the Pyramids

careysub Re:So, is there any shred of EVIDENCE? (198 comments)

This is very interesting, and maybe that's good enough. But isn't there some evidence of what method they might have used? Wood fragments? Tracks? Tools?

I'm asking this as a completely naive onlooker. I'm sure there is research on this spanning hundreds of years; anyone want to provide a quick summary?

How about the edges of the stone blocks that would have rotated about 500 times on their way to the pyramid? There should be systematic chipping on the edges of all of the blocks if this was used. Also, this method of movement looks suspiciously like a wheel, which Egypt did not get until many centuries after the great pyramids were constructed. In a pre-wheel culture this mode of transport might not be at all evident.

Hemp Fibers Make Better Supercapacitors Than Graphene

careysub Re:Potheads assemble! (178 comments)

but love science when it finds uses for hemp

Because with large scale hemp agriculture, you can always sneak in a few rows of 'the good stuff'.

No, you can't - although the belief that you can is apparently what has kept the hemp business shut down in the U.S. for 80 years (and led to Governor Arnold to veto a hemp cultivation measure in California.

The cultivation patterns are completely different. The hemp crop is grown in dense plantings that lead to tall stalks and few leaves, and then the crop is either harvested before it flowers (if an all-fiber farm) or is allowed to go to seed (if hemp seed is also harvested).

Either way there is no way that a successful drug crop, however small, can be snuck in there. (Not so drug cannabis and, say, field corn though - hiding pot among corn is an old trick).

Countries Don't Own Their Internet Domains, ICANN Says

careysub Re: Identifiers (113 comments)

...

that's why a naval blockade is a terrorist act of war, and why Japan was justified in attacking Pearl Harbor

A naval blockade is indeed an act of war. I guess you threw the word "terrorist" in there because - you like to abuse what words mean?

But the U.S. had imposed no naval blockade on Japan before the Pearl Harbor attack. The U.S. had halted U.S. trade with Japan in oil and scrap metal (but nothing else), but this is not what the word "blockade" means. A blockade is using armed force to prevent shipping (or other forms of transport) from third parties from getting entering the blockaded nation. Nothing like that was happening. The U.S. had also closed the Panama Canal to Japanese shipping, but again, not a blockade. Japan was free to go 'round the Horn and on to Japan without interference.

Vint Cerf on Why Programmers Don't Join the ACM

careysub Re: where's the money?! (213 comments)

Thank God money evolved before humans or else we would never exist.

True Dat.

Before money, the world population was less than a million. Now it is growing by millions a day.

Straight-up barter is not money. "Money" arises when there comes into being a standardized unit of exchange that is independent of the commodity being exchanged. Evidence for that only shows up around 3000 BCE at the earliest, at which point the world human population amounted to tens of million, not "less than a million". The early records of exchange though only involved standardized weights and measures of commodities, not an actual currency of any kind. This shows up around 1000 BC for the first time, and at that point there were on the order of 100 million people in the world.

Current world population growth is about 400,000 per day.

Finding Life In Space By Looking For Extraterrestrial Pollution

careysub Re:Advanced? (95 comments)

... It is unthinkable that a civilization that old would still be producing significant pollution (at least of a type that we are familiar)....

We often see posters on /. pitching "terraforming" ideas - perhaps creating a biosphere on a planet that initially lacks one. Evidence of terraforming projects carried out by ancient civilizations are "highly thinkable".

Consider one such proposal for terraforming Mars: by injecting "super green-house gases" - chemicals designed to maximize the greenhouse effect - into the Martian atmosphere. One top candidate for this is perfluoropropane - if we find worlds with significant concentrations of this (or other related chemicals) then this might be evidence of deliberate release.

Finding Life In Space By Looking For Extraterrestrial Pollution

careysub Re:Hey it is another shot at least. (95 comments)

Mod parent up!

More generally - what we are looking for in planetary atmospheres (once we can routinely analyze them) is evidence of chemical syntheses that cannot plausibly can arise from non-living physical processes. The arguments made in several posts above (as if it were some sort of refutation) that oxygen is pollution cause by photosynthetic organisms is absolutely correct - detecting large excesses of oxygen (for example) should indicated living systems. But looking for more exotic chemicals never found in nature (on Earth) is one way of looking for technological (intelligently designed) processes. It does not matter whether you choose to call it "pollution" or not, the presence of chemicals and concentrations that do not arise from non-living systems is a good way to try to detect such systems.

Also the popular form of argument seen on this page that "No intelligent species would..." or "All intelligent species would..." is fallacious at several levels. Intelligent species evolving in different star systems are in no way bound to behave the way a /. poster imagines, and one could reasonably expect different behaviors for species evolving entirely independently. We aren't looking for features that "every" alien would produce, just for features that some alien might produce that can be distinguished from non-living processes. If you never look for something, odds are you will never find it, even if it is there.

Experiment Shows People Exposed To East German Socialism Cheat More

careysub Re:Communism and Scotsmen (619 comments)

It may not count as a formal logical fallacy, I wouldn't care to argue that point, but while modifying the definitions of things after the fact (a Scotsman is someone from Scotland who *also* doesn't do X, Y or Z) may not create a logically flawed argument, but it moves it into the realm of logically true zero-information statements such as "if red is blue then elephants are unicorns". (I forget the technical term)

The last example is called "vacuously true".

Experiment Shows People Exposed To East German Socialism Cheat More

careysub Re:let me correct that for you. (619 comments)

Exactly. The fact that the original article describes East Germany as socialist and West capitalist and then attempts to claim that as the reason subjects were more likely to cheat indicates an agenda....

Indeed there is. The Economist is a conservative periodical, although normally a sane one - and thus would be considered "left" by the former GOP of today. Here though, the temptation for a dishonest smear at "socialism" was just too tasty to pass up. By The Economist's normal standards West Germany was/is a socialist society, though like other successful western socialist societies it is also capitalist (the two aren't actually exclusive, but are commonly found together in mixed systems).

Check out the comments to this fluff piece on their website. Their readers are scathing in their rebukes for this tripe.

(Currently, since Germany has a conservative leader that The Economist approves of, it has been giving Germany a pass on begin socialist, even though the economy and governmental systems have not fundamentally changed under Merkel's chancellorship.)

NIF Compresses Diamonds With 50 Million Atmospheres of Pressure

careysub Re:Diamond monopoly.... (81 comments)

De Beers never destroyed diamonds to maintain scarcity - they just stockpiled them, and then worked to create new markets in emerging economies (the United States, later Japan, then Eastern Europe, now China) and eventually sold them. At one point they had a stockpile equal to several years of sales.

NIF Compresses Diamonds With 50 Million Atmospheres of Pressure

careysub Re:Fusion? (81 comments)

Yep. The main selling point of "natural" gemstones these days is that the lab-made ones are "too perfect!"

Strictly speaking it's because they're "more unique" and therefore "rarer"....

Yet, oddly, the market for natural pearls - by which I mean ones that aren't "cultured", but are formed naturally - collapsed when farmed cultured pearls were introduced, and has never really recovered -- even though they are easily identifiable, far rarer, and "more unique" (I am quoting the misconstruction). Natural pearl production is lower today than it was a century ago. This is a good thing, since it takes pressure off of living communities of organisms, but it is also inconsistent behavior of the market/industry compared to other gemstones.

(I have an explanation for why this occurred for pearls - that "cultured" pearls are considered "real" pearls by the market - but laboratory diamonds are not considered "real" diamonds. Pearls were really, truly rare before culturing made them something everyone could buy -- thus cultured ones were accepted because they expanded the market into a mass market. Diamonds on the other hand were really, truly rare once, but that ended with the discovery of the African diamond deposits in the mid 19th century. After that time they were something everyone could buy, and required an international cartel to manage the supply to keep the price up (in addition to restricting the supply it began an unflagging sales efforts - "diamonds are girl's best friend" - to drive up demand). Artificial diamonds did not change the supply-demand situation, there was already a surplus of natural diamond, but the cartel does not wish for there to be "real" diamonds produced outside of cartel price control. Thus no one who deals in diamonds, and is thus dependent on cartel favor for their supply, will agree that an artificial one is "real".)

The Pentagon's $399 Billion Plane To Nowhere

careysub Re:Stop throwing good money after bad. (364 comments)

The F18 is 30 years old, which is like 120 in fighter aircraft years. We flew the F-86 Saber only 20 years, the F-4 phantom flew 20 (as a fighter), and these are the grey beards of the fighter world from the past. The F-18 is a fine platform, to be sure, but like it or not, it's getting really old for what it does.

Is your claim that the airframes are reaching their service life and need to be replaced by new builds, or are you claiming that an aircraft design undergoes some sort of senility independent of remaning service life?

Please explain why, for example, a new build F-15 or F-18, with 21st century enhancements, would be in adequate to do its job today if that is your argument.

Climategate Review: Round Two

careysub careysub writes  |  more than 4 years ago

careysub (976506) writes "The report by the second of three panels constituted to investigate the conduct of the Climatic Research Unit of the University of East Anglia, has come in. This panel was a scientific review panel set up in consultation with the Royal Society to examine the integrity of their research methods, and whether there research supports their conclusions.

The key assessment:

We saw no evidence of any deliberate scientific malpractice in any of the work
of the Climatic Research Unit and had it been there we believe that it is likely
that we would have detected it. Rather we found a small group of dedicated if
slightly disorganised researchers who were ill-prepared for being the focus of
public attention. As with many small research groups their internal procedures
were rather informal."
