Learned something today

Will wonders never cease, eh?

Reading through some comments on Bad Astronomy BLOG I came across this.
"11 kilopicoseconds as Earth’s escape velocity makes no sense.
http://lamar.colostate.edu/~hillger/correct.htm"

At first I didn't understand what the commenter was talking about. "kilopicoseconds, wtf" I thought to myself. After reading the colostate URL info it struck me, Phil had written "11 kps" in his blog.
"The symbol for a compound unit that is a quotient of two units is indicated by a solidus or by a negative exponent.

* RIGHT: km/h or km·h-1 (for kilometers per hour)
* WRONG: kmph or kph (do not use p as a symbol for "per".)

* BUT: It is correct to say or write "kilometers per hour"."

I know lots of people that use p as "per" but now I know better. I'll stick with the "/" in the future.

Keyboard Shortcuts (Part I)

People often notice that I don't use the mouse as much as most people. Personally I find it much quicker to do a lot of tasks using the keyboard. Therefore I've decided to post a list of keyboard shortcuts from time to time. Hopefully you'll enjoy them and and find them useful like I do. When editing text: ctrl + arrow (Left or Right) > Move the insertion point left or right entire words. ctrl + shift + arrow (Left or Right) > Highlight entire words (left or right of the insertion point). double click > Highlight an entire word. triple click > Highlight an entire line (not sentence). shift + home > Highlight from the insertion point to the start of the line. shift + end > Highlight from the insertion point to the end of the line.
