<quote><p>On the other hand, we now know the complete value of Pi to enough digits that we can encircle the entire Universe and be accurate to the NANOSECOND. How accurate is enough?</p></quote>

You probably mean nanometre here. Nevertheless, I remember an Asimov essay saying that given the radius and even just a few dozen digits of pi, we could calculate the circumference of the universe to a small fraction of an electron. I think he said 70 digits would do.

I don't think your keyboard is connected correctly.

Honestly, it's hard to take you seriously - even if what you say is correct and pertinent - when you consistently misspell simple words. It's "lengTH", which ends in a "TH" sound as in "THis" or "THat", not an "HT" sound as in "unenligHTened". Not to mention "yields", "remember", "numbers", "though", and "polynomially" [although I just did].

Sheesh.

You've endured mockery because of this requirement, but here's what I use: http://www.wallpaperdownloader.com/ is a free utility that downloads daily Bing images and rotates them as wallpaper. Come the holidays they will show up as wallpapers also. It's completely automatic, and you can choose to keep the images to build up a nice collection of pretty pictures, as I have.

Firing lasers at the moon from Earth means it runs into a couple hundred thousand miles of various gases before it reaches space.

200,000 miles of atmosphere? I think you might be off a bit there. That's about 84% of the distance to the Moon.

The Karman line, commonly used as the boundary between atmosphere and outer space, is at 100km. Even shooting a laser at the Moon on the horizon won't come close to your number.

You are in a maze of little twisting passages, all different.
