Exactly twice the distance from one end to the middle.

Maybe I should have waited for Friday when people are possibly more affable

Yeah well, despite all the expected nitpicking (it’s supposed to a fun

My calculations in Excel make it 20.65 km (not metres!)
Sun diameter = 1,400,4000 km
Light year = 9,460,730,472,581 km
Sand grain diameter = 7e-7 km
Size scaling factor = 5e-13
Distance to alpha
Actually, I dont think you can dispute the speed of light. I vaguely recall
reading the metre was redefined so we would have an exact measure of the

I got an Epson from Harvey Norman for about $900. It's resoloution isnt top
of the line but it does the job well enough. I've been using it for almost 2
years (once a month) so it's worked out quite cost effective.

Hi Greg,
If you're ok with buying, City Software has one on sale for $572 on their

You can pick it up from their store in Mt Waverly (if you select that
option).
There's also a BENQ one at a city shop for $489 -
