Greetings, my fellow port swillers!
Whelp, ol’ Robbo finds himself knocking about Port Swiller Manor for the third day, quietly waiting for Pope Francis to wrap things up downtown and head north.
♦ Frankly, I’ve not paid the least attention to the coverage of events so far. For one thing, I absolutely refuse to let the media (mainstream OR social) tell me what I ought to make of it all. For another, I just don’t cotton to anything that smacks of celebrity hype. (Of course, to be perfectly honest with myself I acknowledge that I might be singing a different tune if this were St. John Paul II or Benedict and not Francis.) For a third, as an ordinary every-Sunday foot soldier, I get the same feeling about the outpouring of enthusiasm associated with the visit as I do about the crowds who show up only for Christmas and Easter services.
♦ Fingers crossed, please: Eldest Gel fired off her early-decision application to Sweet Briar College last evening. We should get a yea or nay within two weeks or so. I don’t know why they wouldn’t accept her (good ACT’s, steadily rising high school GPA and a legacy several times over, plus the school really needs to grow its student body again so it’s a buyer’s market), but the process is unnerving just the same.
♦ Watching the con-trails of jets cruising overhead this morning, I got wondering about calculating their distances from my porch. If I assume a plane is at an altitude of, say, six miles and accurately measure the angle of the hypotenuse from my point of observation, using right triangle
geometry trig I ought to be able to calculate the length of that hypotenuse, yes? Or no?
♦ Well, at six and a half games behind with only about ten days left in the season, I just don’t think my beloved Nats are going to catch the Mets. Ah, well. Is it possible that the “Back To The Future, Part 2” prophesy will be fulfilled by the Cubbies taking it all this year? If they make the post-season, I will certainly root for them.
Anyhoo, time for moar coffee.
UPDATE: A glass of wine with Don for putting me some stuff-you-should-have-remembered-from-school knowledge in response to the cruising jet question. All I can say is that it’s been a very long time since I did any trig.
Anyhoo, out of curiosity, I ran a couple calculations, assuming a jet to be cruising at an altitude of 37,000 ft, or 7 miles just to make it simpler. An observed angle of 35 degrees produces a line between my eye and the plane of just over 12 1/4 miles. An observed angle of 20 degrees gives a distance of just over 20 1/2 miles.
The thing is, these results are mighty near what I would have guessed just eyeballing it. Pretty cool.
(And yes, you can see a jet at 20 miles. Or rather, at certain times of day around dawn and dusk, you can see sunlight reflecting off of them sometimes.)
