Re: Not the worst.
Clearly you are all wrong. The worst movie? The Trial of Billy Jack. A pretentious and lame sequal to a lame original. A friend of mine told others to go see it because he knew they would never otherwise believe how bad it was.

From the article: "[...] the Earth had passed its closest in a very long while to the Sun just the day before."
Not exactly. The Moon's orbit precesses so that its perigee changes constantly. The Earth's orbit around the Sun precesses vastly more slowly, with its perihelion currently always in the first week of January.
On Jan 4th, 1912, these two events coincided to within 5 hours, a full Moon. There would have been much larger than normal spring tides around that date, possibly freeing grounded icebergs as the article stated. But, it's a reach to give this a major place in the circumstances of the Titanic's disaster.
'The generally accepted figure for human visual acuity is one minute of arc, so we need to calculate the distance at which one pixel is equivalent to that.'
We want the minimum distance to _not_ see pixels, so you want the distance at which one pixel is 1/2 arc-minute (or less).
' It was the Orbiter that took the first "whole earth" picture (not Apollo) and provided the first pictures of the dark side of the Moon.'
Please, ot the "dark" side, the far side. And not the first. That was the Soviet Luna 3 flyby of
October, 1959. See http://nssdc.gsfc.nasa.gov/planetary/lunar/lunarussr.html for details.
