Very few people in society ever use the Ideal Gas Law outside of Chemistry 101, and the people who do don't use Fahrenheit, or Celcius, they use Kelvins.
I used degrees Rankine in Thermodynamics 101, you insensitive clod.
[the meter is] just about as arbitrary a measurement . . . as we can get. . . The meter is the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second. . . Such a absolute logical base kinda makes one quiver, eh?
Yes, but if you think that's so arbitrary, remember that the yard is officially defined as 0.9144 meters.
No, they used to be marketed as MB, and even lower. And that was when a MB was typically understood to be 1024 KBs and a KB was known to be 1024 bytes.
Air conditioners typically reject 20%± more heat to the environment than they remove from the cooled spaces. The only way to get that down to 0% would be to have no temperature difference between sink and source, but then you wouldn't need A/C. Even a reversible, maximum efficiency refrigeration cycle can't avoid thermodynamics.
Still, compared to other sources of heat in a city, I can't see how that would make an appreciable difference in the outdoors temperature, let alone 2C.
This is just a display problem, not even a conversion problem.
No, it is a conversion problem. True, if you make the column text in the import.csv "wizard" , it won't convert. But if Excel does convert text to a date or to a number, you lose the original text and have to import again to get it back. Numbers displayed in scientific notation (or any other format) and dates displayed however Excel is set up to display them, are stored internally as just numbers, and the original text is not saved anywhere.
It doesn't grant foreigners rights that citizens enjoy, nor does it guarantee those rights to our citizens outside the U.S.
Nor does it grant rights to US citizens. It enumerates certain of the unalienable rights that all people have been endowed with by their Creator (notwithstanding that those rights are routinely trampled on by governments of all persuasions) See the ninth amendment: "The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people." See also the debate the framers had about adding the 'Bill of Rights' amendments to the constitution.
Fact: when you give Amazon a post office box number to ship to, poof; there goes your Prime 2-day shipping
That should be obvious since UPS, FedEx, et al, cannot deliver directly to a USPS Post Office Box.
By the way, where do you live in the U.S. where the USPS does not deliver to you?
I know there are places in the US where UPS & FedEx won't go, but will instead forward the package to the USPS for final delivery, but I'm not aware of any place where it's the other way around.
A reasonable takeaway from this might be that that overly thorough testing of backup power systems can carry excessive risk.
As can underly thorough testing.
I was involved in a project where, due to shitty power infrastructure in South Dakota, an entire call center was put on emergency generators, not just the life safety and computer equipment. It was faithfully tested every week, no problem. But the first time it was really needed, it failed, which cost tens of thousands in lost productivity. Turns out they weren't testing it under load, since load banks for testing cost money. At least that company (Discover) had useful distributed back-up, so no data was was lost, and customers were unaware of the outage.
I'm working on the fueling design for proposed new Emergency Generators at O'Hare (currently out for bid after 3 years back and forth on where to put them and what to connect to them, in spite of simultaneous proclamations on how urgent it is to get the project done, since they have had failures during testing of the existing system.) When I first saw this on the local Chicago news, which obviously showed pictures of lines at O'Hare, I wondered if it had anything to do with our project - thankfully, not.
Anyway, those metal "utility buildings" are probably not fire rated; from your description, they might be just the enclosures that outdoor generators come with. At O'Hare, the existing generators are inside, all located in a non-fire rated room. The six new generators are going into a new building, but separated into two rooms with 4- hour fire-rated concrete block construction, with fueling "day tanks" in separate rated rooms, also. Main electrical gear is going into a separate new building, again separated into 2 fire-rated rooms. Most of the Automatic Transfer Switches are distributed throughout the airport, and most of them are in fire-rated electrical rooms. Almost all of these spaces have fire-suppression systems (FM insisted on sprinklers, rather than CO2, in spite of having 4160 Volt generators). However, if there is a fire, generators automatically shut down. Hopefully, they could limp by with just 3 generators, but I wouldn't be surprised if a fire caused all six to be shut down, especially if the fire department decides that shutting them down manually is safer for their personnel.
Management has to make decisions with imperfect information (like playing poker) whereas engineers are used to working with greater certainty (more like playing chess) and it's hard for many of them to wrap their head around the difference.
As an mechanical engineer in the construction industry, I can testify that working with imperfect information is the normal situation for us. And that "management" often requires engineers to boil down extremely imperfect and uncertain cost data into a singular "hard" number like Return On Investment so they can fool themselves into thinking they are making a fact-based decision. (OK, the better ones realize that there's a huge range of possible outcomes depending on external factors, and try to take account of error bars and the like, but those decision makers are relatively rare.)
On one hand, airlines are not swimming in cash so everything requires a tedious business case.
On the contrary, after going through bankruptcies in recent years and shedding debt, pensions, etc., plus with the current low fuel prices, most airlines are currently swimming in cash.
If you actually look at the charts and graphs on this report, saying there's a negative correlation is a big stretch, especially since I didn't see any numbers on confidence intervals or fitness of the fit. It looks at a glance like there's no real correlation, with most returns clustered around 1.5, and with the compensation fairly flat except for outliers that tend to be greater for the poorer performing companies.
You do know that 98.6F is just the conversion (using an unnecessarily precise decimal place) of the nice, round 37C, and that normal body temperature varies from time-to-time and from place-to-place in the body a lot more than that "98.6" implies?
Not having the metric system here, has never affected my life, nor anyone I know really
Well, you've never met me.
Though by no means a showstopper, it is definitely a pain to work using feet, inches, fraction of inches; square feet, square inches; cubic inches, gallons, cubic feet, acre-feet; pounds force, pounds mass; pounds per square inch, pounds per square foot, inches mercury, inches water, feet water, atmospheres; pounds per cubic inch, pounds per cubic foot, pounds per gallon; miles per hour, feet per minute, feet per second; etc. (Don't even let me get started about the various units for viscosity which don't have linear conversions).
Most air-cooled AC condensing units in the US are rated at 95F outside temperature. If it gets much above 105F outside, you better double check how it will actually work (or not), or maybe special order something that can work at those temperatures.
Is that really 19mm pipe? Or just 3/4" in new measures?
Silly AC. A 3/4" NPS standard weight steel pipe is 20mm DN, not 19mm. And both are nominal sizes - it actually has a 0.824"(20.9296mm) Inside Diameter and a 1.05" (26.67mm) Outside Diameter.
I thought you had to agree to reasonable terms to use the product?
This is not a software license. You are free to do anything you want with a product like a car after you buy it Whose liability it is if you abuse the product is a separate issue, but the burden is usually on the manufacturer to prove that it wasn't their fault.

Scientists don't adapt their hypothesis. They adapt their theory - or come up with a new theory.

Does no one do double entry bookkeeping anymore? Or do they just cut and paste the mistakes into both entries?

Fracking is relatively expensive, and only grew when prices of imported product went up enough to support its costs.

Montgomery Ward was the leader in the mail-order business before Sears existed.

Lampert put together Sears holding for the purpose of cashing in on the real estate Sears owned, not to run it as a long-lived company.
