Depending on the version of the Ten Commandments, the eighth or ninth is “Thou shalt not bear false witness against thy neighbor” in simpler terms, you shouldn’t tell lies, especially a lie intended to falsely accuse another person. I was reminded again, of the damage done by malicious accusations, upon reading this horrifying story, linked through Insty because there was such a malicious person in the neighborhood where my family lived for more than a decade a person given to making random and spurious accusations about his neighbors. When I wrote about my family, I called this residence Hilltop House a post-war bungalow perched on the knee of a range of hills, surrounded by similar and rather modest houses on half-acre or quarter-acre lots, spread out along a rambling tangle of narrow roads above Sunland-Tujunga. A good block away from Hilltop house was a cul d sac of about half a dozen houses; one of the residents in the cul d sac was an older couple … and the man, who I will call Felix S. began to go nuts. Like bankruptcy, it happened slowly and then all at once. He became convinced that his neighbors were all part of a vast conspiracy to manufacture drugs and that there were tunnels and pipelines running the drugs between all the houses around him, and that odors from the drug manufacturing were poisoning the air around his house. Eventually, he put up all kinds of industrial fans around his yard, intended to blow the fumes away, and became notorious as the “Fan Man.” But that came later.
Personal Narrative
Heuristics for Ukraine (and other places)
NB: some of the following is from a recent videoconference that included our own Trent Telenko, who is very much the man of the hour, but some of it is more publicly available, not to mention common sense. First, though, as is my wont, a quadrant diagram to organize my presentation …
I. Theater “Hardware” (physical assets/consequences)
The Proper Frame for the Narrative
I am watching matters develop with regards to the trucker strike, with appreciative interest, seeing that is really another variant of a grass-roots spontaneous civic spontaneity, much like the Tea Party was, some years ago. The Canadian trucker protest has that in common with the Tea Party protesters but the difference might be that the independent trucker community is a smaller, a more cohesive and even more media-savvy and self-disciplined party. The various Tea Party protests were more general, cut across class lines (at least the urban-focused one that I was involved in was, no matter what the establishment national media might insist) and focused more upon voting in various political races then upcoming, and protesting the general monetary incompetence of the Obama Administration.
Privileges
Well, I see from the linked story, that the educational geniuses in Fairfax County have trodden heavily on their essential nether parts, yet again, in their demented crusade to shove critical race theory, or whatever it is called this week to disguise the whole rotten concept, down the throats of hapless students of all colors on the Pantone scale. This time around, they tried to foist off the concept of military dependents being somehow uniquely privileged.
Not Humanity’s Last View …
This is being described as “humanity’s last view of the JWST.”
I expect imaging, and even direct viewing, of the James Webb Space Telescope from terrestrial telescopes to become a popular amateur astronomical activity in the summer of 2022. Here is why:
A full Moon has apparent magnitude -12.7. This is the result of its distance of ≈380,000 kilometers, its effective area (a circle of radius ≈1,700 kilometers) of ≈9.1 million km ², and its albedo of ≈0.12.
The JWST will be at ~4 LD, the effective area of its sunshield will be ≈830 m ², and its albedo will be very close to 1.
Its distance makes it 16 times as faint, its effective area makes it 11 billion times as faint, and its albedo makes it 8.3 times as bright. Multiplying all these together yields a factor of 21 billion.
The magnitude scale is measured in increments of âµâˆš100 ≈ 2.5, such that each 5 steps downward is 100 times brighter. Venus, which can reach an apparent magnitude of -4.7, is nearly 100 times brighter than Arcturus (α Boötis), at -0.05. The stars in the Big Dipper and in Orion’s Belt are around magnitude +2.
The limits of my experience are the Sun, apparent magnitude -26.7, and some of the fainter Pleiades, magnitude +6.5 or even fainter—note that this takes not only very clear, dark, moonless skies, but also an hour and a half or more of no artificial light whatsoever for excellent dark adaptation, and probably eyes younger than mine are now (I am recalling an incident from my 30s). That’s a factor of almost 20 trillion.
Anyway, doing the math, something 21 billion times fainter than a full Moon has an apparent magnitude of +13.1.
Every amateur astronomer reading this just went huh. Easy.
Taking the usual limiting magnitude of the unaided eye to be exactly +6 and the effective aperture of the human pupil to be 7mm, less than 200mm of primary lens or mirror diameter would be enough. In the real world, it’s going to be harder than that … but I found Pluto in my 333mm f/4.5 Newtonian at magnitude +13.8 or thereabouts during a Texas Star Party in the 1990s.
The challenge will be figuring out which thirteenth-magnitude speck in the field of view is actually the JWST, but one thing’s going to make it a lot easier: it won’t be moving with the starry background. Its motion will essentially be at the solar rate, ~1 °/day. That’s 2 ½ arc-minutes per hour, or 2 ½ arc-seconds per minute. A pair of images taken even a few minutes apart will pop it out, much like the discovery images of Pluto in 1930.
