Oh xmas tree, oh ymas tree,
Your boughs can teach a lesson.
With normal trees, and right hand rule,
For geometry, you are a tool
Oh xmas tree, oh ymas tree,
Your boughd can teach a lesson.

I don't know, but I think they can be integrated and derived with some assumptions.mfb said:
Let the christmas tree function c be a function of time, [itex]c(t)[/itex], then
for t < Christmas Day, [itex]\int_{0}^{Christmas Day} c(t)dt=[/itex]
for t <= Christmas Day, [itex]c(t)=[/itex]
for Christmas Day < t < New Year's Eve, [itex]c'(t)=[/itex]

If that's supposed to be linear then their spacecraft probably crashed somewhere.

They gained about 3 meters in 5 trials. Extrapolating, attempt number 170,000 or so will reach space.

Sometimes it is even damaging for people! A guy in TX once shot his computer out of frustration. A feeling most of us users can share. They had put him in a psychiatry. So do not shoot at things in the US. < ... censored ... >Ibix said:

There was a story on the Daily WTF about someone demanding a warranty repair for a computer with shotgun damage. Very glad that she'd phoned, rather than showing up in the shop shotgun in hand they said they doubted it was repairable, and anyway it wasn't warranted bulletproof. Eventually she went away, but a week later called in triumph to tell them that another shop had repaired her computer, and how she was taking all her business there etcetera. They managed to get the name of the other shop, and it turned out they knew someone there, so rang to ask for their side of the story.fresh_42 said:
Apparently they'd just seen an opportunity and said that they'd see what they could do and warned her it might be expensive. Then they'd discovered that the hard drive in that particular model was at the bottom of the case, and she'd hit it high enough that the drive had survived the otherwise almost complete destruction of the machine. So they swapped the hard drive into a new machine and sold it to her, billing it as a repair.
