@steven-metelsky Hmmm. If I inverse between NGS marks KV5560 in Trenton, NJ and AD9364 in San Diego CA, I get 3,853,254.4307 meters, or 3,853.2544307 ...

@holy-cow Also Office Space. Milton lost his Swingline but burned down the building and left with the check.

@dave-lindell Yes, that's similar to what Newton's Method does, but Newton uses the derivative of the function to speed up the convergence. I like li...

@dave-karoly That's what I got. I think that 1,070 feet and 3/8 inch will get 6 seconds.

@monte Are you sure about 3/8", 200', and 6 seconds?

@holy-cow But 1330.03 feet has six significant digits. And 665.015 has six significant digits. So, from a significant digits viewpoint, 665.015 feet ...

@paul-in-pa The real world differs from the theoretical one; that's why I like Einstein's little quote so much.  The functions that we use to r...

@andy-bruner Here's how I did it. (Remember, my students always accused me of doing things in the hardest way, so there are probably easier and more ...

@holy-cow A bit of overkill, and pretty useless, but I have a simple excuse. That's what the calculator got!?ÿ :silly: If you make the distance from...

@paul-in-pa The width is 12.311857 feet and the intersection is 7.8114542 feet from the left wall.

@bill93 Right. The tangents are irrelevant to the problem. I was just extending it to a more common format.

@tommy-young You're not alone there. I want real books for Christmas. My thought was that the book may be too valuable to use, so let Office Depot pr...

If you want it for reference, you can download PDF here: There's some other neat stuff here, some downloadable and some not.

3000. There is only 1 significant digit in 7, so that dictates only 1 significant digit in the answer. Try this problem here, first using 7 and then u...

@mightymoe Perhaps. The number on the sign is exact for international feet and is the same as the one for US survey feet, rounded to 4 decimal places...

I see. The distance between two fixed points should be the same on either system even though the coordinates are different.?ÿ The question was interes...

Looking at the table here, ?ÿ OS-GPS-2002 is for older systems. Perhaps you need FieldGenius 9 or newer.

@am95405 Nice article. Dr. Willingham hit the key issues and had a suggestion or two that might actually work. A real issue, though, is finding peopl...

@holy-cow Yes, just one clock for everybody. Horatio is not involved in the time. Last year, my son was cooking something for his aging parents that...
