Hello, England. Thank you for everything. Love, U.S.A.

Sorry. Cup of tea anyone?

(Juxt) OK. Thanks for giving us jazz. And Tom & Jerry.
(Duj) The only piece of Australiana I have is a home-made boomerang (Specifications in New Scientist 1974.) It's big and doesn't half go but has to be thrown left-handed. They're not symmetrical.

[Rosie] I have found that turning them upside down usually helps. Then again I'm no expert any more than I'm a left handed sort of a bloke. Keep in mind, Rosie, that the heavier boomerangs were not designed to return but to stay in the air long enough to knock the noggins of the target.

[rab] Didn't realize the lakes were so stormy ;o)

Not too nice down here either. (Softers) Good science.

Zero degrees here. *throws snowball at morniverse*

(CdM) Where are you at the moment?

[Rosie] -37.15; 146.43

*receives grease-stained envelope containing strange hard lump in the post* ;o)

(CdM) Not surprised it's snowy up Mount Buller. An assumption, of course, because you have quite unforgivably omitted the ρ-coordinate, which I take to be 6378137 + 1805 m. Greetings, anyway, from 51.32; -0.06, 6378306 m.

So "on the surface of the earth" is not the default, then. :-)

(CdM) Yeah, OK. Equally, I have committed the unpardonable sin of assuming the earth's radius is constant at all latitudes, which is not true. The polar radius is 21.4 km less than the equatorial radius. It's uphill to the equator.
