As someone else posted above, if you look at it from the opposite direction, it still twists right.

Find the nearest screw or bolt (almost all will be right-handed), pick an end to be up, point your right thumb in that direction then curl your fingers: your fingers will curl in the same direction that is needed to move up the spiral. Now flip the bolt or screw upside down and try it again... Yep, still works. Now try it with your left hand: your fingers will curl in the downwards direction. That is what is meant by right-handed or left-handed.

Well I suppose in-flight engine fires don't count, if no one dies...

I had a large group of buddies who got a "free week" in Japan in late August or early September 2000 (I don't remember precisely when) following an engine fire as they were flying back from Korea to California. As they were Reservists whose "2 weeks of training" already ended up being 3 weeks (before the incident), their civilian employers were none too happy! My flight was a fewdays later on a normal commercial airline, and I actually beat them home.

"The three-engine DC-10 entered service in 1970 as a passenger jet, and the last airplane working in that capacity, operated by Biman Bangladesh Airlines..."

Did anyone bother to check on World Airlines, which only flies passenger charter flights for the U.S. Military, and (mostly) flies in and out of military air bases? Before I left the Army a few years ago, I had the (dis)pleasure of riding their sketchy DC-10's and MD-11's several times. Also, neither of the two planes can cross the Pacific Ocean (California or Washington to Japan or Korea; and vice verse) in one hop, on those routes there is always a refueling stop at Anchorage or Honolulu.

In case you haven't noticed, manufacturers of transistor based memory (flash, SRAM, DRAM, EEPROM, etc.) still use the 2^10 definitions. To this day, I still can't believe the marketers convince IEEE to make up the silly sounding names for the 2^10 definitions. If I had a say in the definitions, I would have tagged on subscripts of 2 and 10 to the end of the units to indicate the difference.

By the way, under both sets of definitions, 1024 bytes = 1 KB = 1 KiB. It's only for MB and higher that it diverges.

Are those amp values load amps or breaker amps? Just running the raw numbers provided (and neglecting power factor) thats 145320 W coming into the rectifier and 49200 W going out... a whopping 33% power efficiency! 33% efficiency isn't all that much higher than a typical internal combustion engine.

Another problem with all of this is the cable sizes that are required... 120 Amps is 2ga. or (most likely) larger cable. Cables that size start getting heavy and stiff pretty fast.

At any rate, I here Teslas are fun to drive (at least while the charge lasts) and that's all that really matters, am I right?

When using computers, there is one way in which English measures are unbiasly superior to metric units, which is that the standard practice that subdivisions of the small length unit (the inch) are base-2 fractions (i.e. 1/2", 3/4", 5/32", etc), rather than decimal (i.e. 11.3 mm, 15.923 mm, 2.71 mm, etc. ...just examples, not conversions). Why is this superior? Numbers are represented in binary on a computer, decimals will not neccessarily convert without a small error. Usually the difference is negligible, but errors can build if you are adding a long series of values or multiplying by large numbers.

I'll concede that weight, volume and the large length measures can be a little confusing though.

One thing that gets missed in this whole year-round school debate is: when is the school going to have time for major maintenance, repairs, and renovations? Many schools are already packed through to the brim (in terms of classroom capacity) so it's not like they can close down an area of the campus/building to get work down while class is in session; construction noise and construction zone safety are major factors too. Ever been on the floor above when a construction worker is using an impact driver into a wafer ceiling?? If you have, you have probably noticed it's louder and more annoying noise for you that for the construction worker. On the safety side, do you really think it's a wise idea to do a crane lift of a large HVAC unit while there are unwatchful, unrulely, or apathetic students down below?

Google an image search for "siemens sentron busway" (busway is just Siemens' lingo for "buss duct", but "busway" can refer to other sorts of devices, too). There are other manufacturers, but that's just the first model name I remember.

Buss Duct is accepted industry spelling of the equipment being referenced.

Technically, the notice is called a "Failure to Register with the Selective Service Notice". I had one forwarded to me after I had already been in the Army 4 years (I enlisted a little before my 18th birthday), and was already serving in Afghanistan. I called the contact number, and the exchange went something like - Me: "Hi,this is Specialist [MyRealName], U.S. Army. I received one of your Failure to Register notices. I'm kinda in Afghanistan right now, what am I supposed to do with it?" Helpdesk person: "Er, umm... our apologies... umm, Soldier. Uh... thanks for serving. We'll update your record. What's your Social?"

We need checkboxes instead of radio buttons on this one.

And don't look at me like that! I live near Seattle where there is plenty of open water and plenty of Indian Reservations to buy the good stuff at.

Just so you know (and a lot of people get this mixed up), 120/240V in the U.S. is not 2-phase power (with the exception of one small hydroelectric served area of upstate NY, which actually has some relic 2-phase generators)! You are receiving single-phase power off a 3-phase transmission system (typically, one residential neighborhood will be on the same phase), with a center-tapped/center-grounded step-down transformer providing service to your home. "Split-phase" is a more appropriate nickname for a center-grounded single-phase electrical system.

You can purchase LED "tube" replacements for fluorescents. We've been testing them out at my workplace, and, generally speaking, the building staffers seem to like them better than old fluoresent lamps. The catch is that you have to re-wire the fixture and bypass the old ballast module.

Diesel (except farm diesel, which is exempted and has a dye additive to distinguish it) currently is Federally taxed, per gallon, identically to gasoline. It used to be taxed at a lower rate, but congress let that one expire during the Clinton administration.

It's also sitting higher than the estimated combined value of all the earth's gold, silver, and platinum (already extracted and unproven reserves included) which is about $15T (source: National Geographic's "Secret History of Gold"; this special didn't relate that number to U.S. Debt, it was my own observation).
