Today’s post comes from NorthShorer.

Four weeks ago the night after I had the useless shots in my back I could not sleep and decided at 3:00 a.m. to take out the garbage. When I opened the door to the garbage room, I walked into a wall of lights.

The owners of our building finagled two grants to install LED lights throughout the building at only slight cost. I have been hearing about this for a couple months and imagined, I suppose, a few small boxes of bulbs, not that pile, which is only half the bulbs for the hallways, security lights, garage lights, and parking lot lights. Another pile even larger was in the other garbage room at the other end of the building. Reminded me of a few stories of people who failed to estimate the weight and volume of pennies they either ordered or amassed. To be fair these new lights are not just bulbs; they need new fixtures. For instance all the standard recessed tube lights in the three stories will be replaced by a same size fixture holding several LED bulbs.

What also is surprising is how much brighter are the LED lights in the garage and hallways. Our yard is almost daylight from the new security light above us. I have avoided LED lights because they gave such dim light.

On Wednesday they will install LED lights in the attached lights in all apartments, which is nice for me because I cannot reach the ceiling lights. They will also cart away for free all of the fluorescent bulbs we have. Our apartment is about the average. It will get 27 new bulbs. The building has 65 apartments, plus eight other rooms to get bulbs. 27 times 65 equals 1,755 bulbs. Add in another four dozen to get, say, 1,800 or so. How big a pile will that be? I bet each will come in a protective carton. I happened to be in the Batteries Plus store recently. The owner noticed my address and said he was supplying just the bulbs. He, too, had underestimated the volume. The supplier told him the bulbs would have to be shipped to the apartment building because they would not fit in his strip mall store.

All the medical facilities in this town will soon get LED bulbs under a grant from the same sources. There are six large clinics and the massive hospital, plus a couple smaller ones. What will those piles look like? I am pleased for this change because the tube lights give me a bad headache while I wait around.

Estimation is a vital skill. Schools are doing more to teach it, for one thing to try to get kids not to just accept what their fancy graphing calculators say. I am usually rather good at estimation, except in extraordinary events like these lights. I am very good at estimating distances and travel times. For weights I am usually far off. I know what time it is quite well without using a clock, a skill I developed working outside as a child. I don’t have to be outside seeing the sun to do this. Not sure if this is estimation, but I almost always know which way is north. When I do get turned around, I get agitated. I used to astound my partner with this ability plus the ability to remember routes we took on a previous visit, sometimes months before. In the post and common roads of the Northeast that is a challenging skill.

The students used to be astounded by how the chemistry teacher and I could quickly estimate calculations and come close. He was a very intelligent man and knew rapid calculation skills. His estimations were often exact..

I am intrigued byhow computers find complex answers through a series of estimations instead of seeking an exact answer when it is not needed. This shortens the time for calculation, often by days.

How are you at estimation of volume, distance, weight, time needed for a task? Do you know what time it is without looking at a clock? Do you know which way is north on unfamiliar ground? Can you guess the number of beans in the jar? Do you always measure carefully for recipes?
