Tom contemplated the boy a bit, and said: âoeWhat do you call work?â âoeWhy, ainâ(TM)t that work?â Tom resumed his whitewashing, and answered carelessly: âoeWell, maybe it is, and maybe it ainâ(TM)t. All I know, is, it suits Tom Sawyer.â âoeOh come, now, you donâ(TM)t mean to let on that you like it?â The brush continued to move. âoeLike it? Well, I donâ(TM)t see why I oughtnâ(TM)t to like it. Does a boy get a chance to whitewash a fence every day?â That put the thing in a new light. Ben stopped nibbling his apple. Tom swept his brush daintily back and forth â" stepped back to note the effect â" added a touch here and there â" criticised the effect again â" Ben watching every move and getting more and more interested, more and more absorbed. Presently he said: âoeSay, Tom, let me whitewash a little.â

Also this article says it is too hard to do a CFD...
"The wide range of time and length scales relevant to turbulent flows at realistic geophysical and astrophysical parameters prohibits direct numerical simulation, and makes any computational study difficult and time intensive."

Because the power of CFD and FEA is iterative. You create a math model and simulate the results. Then you test the results to see if they match your prediction in the lab. If the results are not quite exactly what you calculated then you can adjust them with factors. Instead of building 80 prototypes, you only have to build one.

Same thing happened with Time Warner cable. You used to be able to create web pages and FTP to your personal directory. Then you could only use a stupid python website generator. Then they just totally took personal web pages away. (No suprise that no one wanted a "custom" web page generated to look like it was made by a ten year old.

I work as a mechanical engineer and all of the old tooling for stuff is in inches. You don't realize how much stuff you use everyday is designed in the 1950's.
To just re-tool all the fixtures, inspection guages etc. is very wasteful so as it wears out then you try to do new stuff in metric.
There isn't any version of pipe threads in metric that I know of besides o-ring boss ports.
Also to be politically correct, most drawings made are dual dimension (english and metric) if you design it in inches. So what is the big deal?
It is easy for somebody in another country to read dual dimension drawings.
One thing I will say I hate about metric is that if you design a part in inches then the conversion to metric is okay.
If you design a part in metric, the conversion sucks because it is common to display inches as 3 place decimals and mm as 2 place decimals.
This leads to all kinds of arguments during inspection and part approval.

Wow, man somebody is on the ball at Wikipedia. Inertia is one of my favorite topics and somebody has already corrected this entry which used to say:
Source of Inertia
There is no single accepted theory that explains the source of Inertia. Various efforts by notable physicists such as Ernst Mach (see Mach's principle), Albert Einstein, D Sciama, and Bernard Haisch have all run into significant criticisms from more recent theorists. A review is given by Vesselin Petkov (2009)[12].
For a recent treatment of the issue see C. Johan Masreliez (2006)[13]. Masreliez has published more on inertia related issues that may also have a say in solving the Pioneer anomaly.

I love WiFiFoFum. I use it all the time because I don't have a data plan. I think the reason they are removing them is there is recently some news story about how people are using wifi finders to find laptops located in cars and steal them.
