How do you measure this thing? In progress...


I'm troubleshooting.

Okay. I mean, after all, this endowment thingy seems to be very important to some people. Armed with a 100' tape measure, I go forth.

Now being mathematically inclined, I knew that I first needed to establish a reference point from which to measure. I chose the corner behind my desk where the walls and floor meet as the Origin, with the planes of reference being the south wall (SW), west wall (WW) and floor (F).

Sans trousers and briefs, the Base set of planer measurements were 3.42’ SW, 3.42’ WW and 1.78’ F with a measurement error of ± 0.03’ due to random background noise from the couple procreating in the upstairs apartment.

Since the objective end point will have both direction and magnitude, the Base measurements are represented as the vector:

B = 3.42 ± 0.03 i + 3.42 ± 0.03 j + 1.78 ± 0.03 k

Utilizing a suitable catalyst, the Primed figures obtained were 3.45’ SW, 3.45’ WW and 2.30’ F. An error of ± 0.09’ was noted, probably from personal platform instability and an increase in the upstairs background noise due to a loose headboard. This Primed condition can be represented as the vector:

P = 3.45 ± 0.09 i + 3.45 ± 0.09 j + 2.30 ± 0.09 k

The resultant Erector vector will be the difference between the Primed vector and Base vector (i.e., E = P - B). However, since measurement errors are present, the maximum and minimum Erector vectors must be calculated. Therefore:

Max_E = Pmax - Bmin = ( 3.54 ‒ 3.39 ) i + ( 3.54 - 3.39 ) j + ( 2.39 - 1.75 ) k
Max_E = 0.15 i + 0.15 j + 0.64 k

and

Min_E = Pmin - Bmax = ( 3.36 ‒ 3.45 ) i + ( 3.36 - 3.45 ) j + ( 2.21 - 1.81 ) k
Min_E = ( -0.09 ) i + ( -0.09 ) j + 0.40 k

Member Endowment, being a scalar quantity, will be the magnitude of the resultant Erector vector. Therefore:

Max_E_ME = | Max E |

Min_E_ME = | Min E |

And for those so inclined, the rest is obvious.

Um ... I'm totally confused but wondered - would you balance my checkbook for me?

Good Lord! It's that big? (orders up the cam from satellite service to confirm his measuring)

i think i got it! but with some reservations.
first, i haven't had to think in vectors since my early school days.
second, vectors in my experience used to be represented in metric units.
still, i think i got it... and if my calculations and asumptions are correct, may i just say, very respectable... very respectable indeed...
