Yes, really. The wikipedia article on Radiation Pressure explains it fairly. Also have a look at the one on Solar Sails.

Ahh, I see. You were referring to the youngsters born in the 1940s :-) It seems the liturgy was translated by a committee in the early 1960s. I would have thought the creed would have been translated before that, though. Isn't is used in some Presbyterian churches?

Oddly enough, I remembered the creed as "Tha mi creidsinn" but when I Googled it it said "Tha sinn" so I assumed my memory was at fault.

Perhaps I'm misunderstanding (I will get around to around to studying languages some time!), but that doesn't seem to be a particularly new formation to me. The Nicene Creed begins, "Tha sinn a' creidsinn ann an aon Dia" and that translation has been around a while. At least since I was a child and had to learn it at school ;-)

Did they refuse you for confusing "who's" and "whose"? ;)

What does this mean? I assume that "shouldn't" is linguistic shorthand for "historically didn't but now do"; but I mean can you give me an example of where this happens and has changed. Thanks!

Yes, they have. It's a *trend*. Look at it over a longer time period. By definition, you can't tell when a trend has stopped as it's stopping.

With 99% of software packages you can indeed just "mess around with it" and pick up the basic usage. Not with 3D packages. Install Blender and then do the Complete Newbie tutorial. You'll be glad you did!

Actually, it's every 2 years. The 18 month period was from David House and referred to computing power (due to the combination of transister count increasing and speed increasing).

And the answer to your question would appear to be 2011 :)

Any kind of percentage growth is exponential growth. Taking your 4% as an example, means doubling in size every 17.67 years. In other words, you can consider it as 100% growth over that term.

You can calculate the time it takes to reach 100% growth, at rate r%, with the following (I'm using "ln" to represent the natural logarithm since that's what spreadsheets use):

=ln(2) / ln(1 + r)

So, for 5% growth per annum, for example, it's

=ln(2) / ln(1.05)

which is 14.21 years.

That's why percentage growth of any kind is unsustainable over the longer term.

No, it's not. What gave you that idea?

What you really need to try, though, are the Tutorials. They're under the Help menu and actually consist of SVG documents opened in a normal Inkscape window. It's simple yet brilliant -- when talking about a feature it simply suggests you try it there and then on that document. You should give it a try. Inkscape is an example of documentation done *right*!

No they haven't. Remove the "large" donations and you'd change the average by about a cent or two.

Oh no! It could be split, say, 10 ways between all those options. And then, if you're an indie game developer, there might be as many as three of you in the company! That only gives you $20,000 each for the two weeks! Barely worth getting out of bed for, huh?

Don't you microsofties have to spend some of your time on research? Or are you allowed to make up whatever crap you like as long as it's negative to humanity?

You can't really wreck havoc. Havoc is chaos; it's about as wrecked as wrecked can be. You could *cause* havoc. Or, in other words "wreak havoc". That's a different matter...

Well, £4 anyway. Maybe if you're cooking for 400?
