If I wanted to watch whales in Norfolk, I'd probably got to the coast rather than climb a steeple- but whatever floats your boat.

If you do a search for paleo entomologistI did.
They must be taught that 2 is enough if the family is to enjoy a high standard of living.You can not teach them that if it is not true. In many parts of the world, the only security you have in your old age is that your children will look after you.
Experience will show that they are wrong, at least in the UK.Earth calling Alan; most people do not live in the UK (or anywhere much like it).
Yes they will. They will label the six directions (NSEWUD) with their own words for them, and those six words will correspond precisely with ours, not some random directionsProbably.
The plumb line only hangs vertically at the equator,For a particular definition of vertical. (essentially: "points to the middle of the Earth").
Er, no it doesn't. Gravity (G, in black) acts perpendicular to the earths surfaceYou have assumed a spherical Earth- often a reasonable start, but not in this thread about the Earth not being a sphere.
what are you hoping to achieve here, and why is this so important to you?Science, because this is a science page.
So... don't post conspiracy tosh on a science web-page then...If you want to look smart, be honest truthful and help your neighbor.Why are you trying to fool people in the first place?I just like to look smart because I'm not.
I came up with nothing,You do realise this is a discussion forum, don't you?
new computer programming was installed to correct for the flaw.
If you read you will see that nearsighted is mentionedYes.
New optics do not require such large lensesThey don't use lenses much.
computer enhancements actually now do much of the focusingOnly one of us has ever studied optics.
The fact remains that when the Hubble was launched that a supposed serious flaw in the mirror made it IMPOSSIBLE to focus to the stars.It also made it impossible to focus on Earth (or the Moon for that matter).
So focusing on Earth was the purpose of the HubbleIt could not do that.
the designers hoped that it would also function on the starsWhy do you claim that some of the best optical designers in the world- the ones who made spy satellite telescopes- were too stupid to realise that a bad telescope does not work?
That's nonsense from a number of points of view, not least that, a telescope is a telescope. You grind the primary mirror to a parabola whether you plan to point it up or down.The Hubble telescope started life during the "cold war" as a modified version of a high technology reconnaissance satellite system.
I understud about six units were built but never put into service.
As the cost consists mostly of the research and develop time would it not have been expedient to have built at least one spare
Actually the reason that the Hubble's mirror was defective is because the Hubble was not meant to view the stars but meant to view the Earth as a spy satellite would, or read Gorbachev's mail in Gorbachev's hand, as it may be. Not sure if there were more as the mirrors for these things are very hard to produce
To be honest, I don't really know. It seems reasonable to me that you get a curve because, if you imagine looking at a grating in this way, you would see it as foreshortened more at one side than the other. I realise that's not a clear explanation.This is the comparable image using a diffraction grating (rather than a single slit) at an angle to the beam.What's the expectation based on? Is it derived from Huygen's principle? How?
Again, it's curved as expected.

People who take it are guinea pigs in human experimentation, not taking a drug deemed "safe" by FDA.This idea of being "safe" is a bit silly.
