This thing intrigues me:
They're constructing a new multi-story building right behind ours. I can see it going up from my den windows. Being a builder myself I'm pretty good at geometry and figuring out how things work, but this crane thing has me baffled. The large concrete weights hanging off to the right are obviously meant to counter-balance the weight being lifted on the left side. So far, so good. But as you lift a load and slide it towards the mast, to maintain balance shouldn't the counter-weights slide in too? In practice, however, the lifted weight varies and moves, but the counter-weight never does. Are there some new laws of physics at work here that I missed? (Maybe I should have paid more attention in class?)

Yesterday as soon as granddaughter Blakely was born they weighed and measured her, but then a few minutes later they took her to the nursery to "officially" weigh and measure her. In between times she messed in her diaper and the new mom dutifully cleaned and changed her. The nurse was slightly upset when she found out because she said this could change the baby's weigh-in. Turned out to be a non-issue. Her weight varied by .02 pounds, not enough to matter. Which got me to thinking....when those little diapers say they're for 6-12 pounders, they're talking about the baby's weight....right??

Maybe I think too much....
