It is very clear that Debragh is not looking at 'raw' test scores. It is clear that some scaling has bene applied. the raw test scores might have been integers between 0 and 60. Each of these scores is 'mapped' to a new scale that goes up to 100. The mapping is not linear.It may be that a 60 maps to a 100, a 59 maps to a 99, a 58 maps to a 98, and a 57 maps to a 96. That would produce the gaps. the raw test scores would not produce a bell curve either. If it a a multiple choice test, the low end will be skewed by random guessing. It is also possible that differnet school district encourage different groups of students to take certain tests. Very often, raw scores are mapped to a bell curve, raw test scores sledom look anythnig like a bell curve. Think about that. If you are takng the ACT, the differencve between a 36 and a 35 might be missing a single question. However, the difference between a 21 and a 20 might be missing 2 or 3 questiosn.
Uless you can some that they scaling was applied unfairly, that some student's tests scores were adjusteed up and other were not, there is really no indication that there was any wrong doing.
Because it is unrealistic to expect the less academically adept folk to go onto college, get a degree and a job that requires one. It is exactly the same thing as advising the less athletically adept folks to look at jobs that do not require them to be professional athletes. This does not mean that Engineering is only for non-athletes.
The statement should be obvious, but it really is not. In the last several decades we seem to have fallen into the belief that college is for everyone. It really isn't. People need to be told this.
Neither mA nor Volts is a measure of power. A standard AA cell produces about 1.5 Volt of potential across its terminals. Depending on the application, the current draw (Amps) can be anywhere from a fraction of a microamp to around 1 Amp. The power (Watts) that a AA cell delivers is the voltage time the current, and can be anywhere from a fraction of a mircowatt to more than 1 Watt. The energy (Joules) that a AA cell delivers over its lifetime is the power multiplied by time and is around 10,000 Joules (about 2.5 food Calories). The amount of energy (joules) deliverd depends greatly on the amount of power (Watts) demanded from the cell and is significanty diminised in high-power (Watts) applications.
You can buy special lithium chemistry AA cells for high power (Watts) applications. These deliver the same voltage (Volts) as standard alkaline AA cells and actuall contain about the same amount of energy (Joules). The difference is that they can deliver high amounts of power (Watts) without diminished capacity (Joules).
Brake hard, brake often. And if you are rear-ended at an Intersection in FL, remember that the State has hundreds of millions of dollars in the pot. Sue appropriately.
It does not matter if the intersections actually has a red light cameras, nor does it matter if the length of the yellow at that particular intersection has been decreased. It is the threat that counts.
Oh, there are lots of reasons to complain. Airing only 13 new episodes a year? Taking two years to airs a 'season'? New episodes that never quite matched the quality of the originals?
If the car's AI cannot handle the situation, control of the car could be transfered to a central location where a human could take over. Another option would be to get the car to a safe spot and have a human come out and take over.
Also, the cars don't need to go anywhere at anytime under any conditions to be useful, they just need to be able to follow pre-determined courses safely. In the even of an accident, detour, heavy traffic, or even bad weather, the automatic driving cars could be sent home or told to stay home.
The big market I see is getting elderly people to and from simple destinations like the grocery store, the doctors office, etc. If the driving conditions are not ideal, the trip can be cancled.
Basically, there have been 480 cases of magnet ingestion reported in children in the last decade, with nearly half of those cases reported in the last year. This is not necessarily injuries, but simple ingestion. Are kids actually swallowing more magnets these days, or are parents and doctors simply more aware of the danger? The article's title claims that injuries are are the rise, but makes does not state the actual number of injuries.
Does anyone have any good statistics on the number of people actually injured by ingesting magnets? How does it compare the to the number of children seriously injured by ingesting alcohol, cigarettes or bullets?
Buckeyballs brought the dangers of magnet ingestion to everyone's attention. That is not a bad thing! Small, powerful magnets are not going away (I hope) and scanning for magnet ingestion may need to be a routine test for kids.
You missed the main failure of the analogy. A vacuum cleaner requires electricity. Anybody can generate that electricity. It does not require special electricty from the Hoover Corporation's electricity server. It would not be illegal to modify your vacuum cleaner to work off of batteries or a portable generators.
It is not the Internet connection part that bothers me. It is the long-term availability of the DRM servers and the control that they have over my purchases, long after the sale.
Neither ruthenium nor iridium should be particularly toxic. Because of their rarity, very little is actually known about their toxicity. The metals are very inert, and most of the salts are insoluble in water. Their toxicity should be similar to platinum. Ruthenium currently trades for about US$100/troy oz, iridium trades for about US$1000/troy oz.
Between automatic cameras, GPS, and OBD we could completely eliminate speeding. Or, at the very lease, insure than anyone who speeds _even a little_ is instantly ticketed. If speeding really is dangerous, maybe we should take these steps to eliminate it. If speed limits are too low, maybe we should raise them. But we seem to prefer these strange cat and mouse games.
A gallon of gasoline contains about 31,000 food calories. I your car gets 31mpg, it takes 1000 calories to go a mile. This site (http://www.ehow.com/about_5369136_many-calories-biking-burn.html) claims that it takes about 42 calories to go a mile on a bike. This site (http://www.runnersworld.com/weight-loss/how-many-calories-are-you-really-burning-0?page=single) claims that a 150 pound person burns about 112 calories.
CO2 output should be roughly proportional to calories burned.
You might actually be able to make a plausible argument that a full bus produces less CO2 than the same number of people running.
Brand-new electronic componets are unbelievably cheap. A reel of 5000 resistors is less than $7 these days (http://www.digikey.com/product-detail/en/RC0603JR-0710KL/311-10KGRTR-ND/726700). Most surface mount components are not worth desoldering.
You can buy all the red laser pointers you want for about $1 each if you know where to look.
For high voltage experiments, you are (probably) better off with Neon Sign Transformers than with CRT fly back transformers. Modern fly back transformers tend to be very picky about there drive signal and are ridiculously easy to destory. NST's simply plug into the wall (and are still ridiculoulsy easy to destory).
I am a huge hoarder of electronic junk and I have thrown working TVs and monitors away.
The motors in old VCRs and CD players are actually kind of fun to play around with.
And if you truly believe that abortion in murder, you can not allow it in any case. That includes pregnancy by rape. It also implies that any miscarry should warrant a full police investigation.

A better solution would be to simply lease the batteries and not worry about getting the originals back. The lease would cover wear and tear.
I imagine most people would want their original packs back.
This goes for LED brake lights, LED Christmas lights, and LED traffic light, and roadside LED signage.
I find the PWM flicker of LED brake lights _VERY_ disorienting.
Monitors I can aviod.
Home-built cards on wire wrap boards.
And the computer came with a full set of schematics.
Unfortunately, one of the clock phases was missing on the expansion connector.

Because when you average it all out, no one really lost anything.

I can do better than that:
I predict you are not homosexual.
That should be 92% - 97% accurate.
