And how, exactly, is she supposed to put her knees in any other position? The seats are not very wide. Unless she has an empty seat next to her (and, frankly, that's about the only way I can stand to fly any more), if she tries to bend her legs so that her knees aren't right in front of her, parts of them are going to be spilling over into and annoying the person next to her, or sticking out into the aisle and getting run over by the carts that the flight attendants drive trhough trying to get people to buy stupid duty free stuff.
The problem is not inconsiderate assholes. The problem is that 6'2" people are stuck in plane seats that they simply don't fit in. The problem is that airlines have designed coach seats to work for the bottom 30% of the population in terms of size, and are trying to squeeze the entire population into it. Something somewhere's gotta give. The person in back can blame the person in front for reclining their seat (as we've seen in this thread), or the person in front can blame the person in back for having knees (as we've seen in this thread), but *somebody* is going to be unhappy, because the situation is set up so that somebody has to be.
The problem is coach seating. It's just become too small.
In this case, though, he's not wrong.
That depends. Having a holistic view of history is a good idea. Having a history teacher try to teach the Big Bang and Cosmology is a very, very bad idea.

I wonder how they expect people to read it in their browsers without the text of the document being transferred down to the computer on which the browser is running...?
Well, this method comes from physicists.
Clearly string theorists since, according to the summary, it creates a "dodecadron" cross-section. So having a cross-section somewhere between a 2D dodecagon and a 3D dodecahedron it clearly relies on converting the block into some multi-dimensional object with a strangely dimensioned cross-section.
Takes some seriously Orwellian doublethink to pretend copyright enforcement isn't censorship.
I think this is the result of a very narrow view point when making the map. They seem to only care about censorship by the state through direct laws. Increasingly in the US, and so some extent the rest of the western world, it is not government which restricts our rights but companies. They need to make a second map showing countries where companies have used laws to force, or bully, people into being censored through the threat of massive financial penalties.
All the major credit card companies will be rolling out soon-to-be-mandatory chip systems for their credit cards.
They already have done several years ago. Wherever you are is about 5-6 years behind the times.
Since Einstein, we know gravity is the curvature of space-time. It may be represented as a force in calculations but in reality there is no force.
How about I turn that around and say that Einstein showed gravity can be modelled by the curvature of space-time but in reality it is a force? The fact of the matter is that, at a fundamental level, we have no clue what gravity is. However you can represent it very well by a spin-2, mass-less particle which couples to a particle's 4-momentum (the caveat being that you cannot make this theory work without an energy cut-off at some scale for which there is no justification). Until we solve quantum gravity we simply do not know what gravity really is but, if I were to bet, I suspect the latter is closer to the truth but needs some correction for the quantum structure of space-time which is something we have no clue about.
If gravity is not a force then do we really have a hierarchy problem?
Yes, and if anything it would be worse. The current problem comes about because we cannot scale the Higgs corrections up to the Planck-scale where we know there is new physics. If we remove that scale then we have a theory which has no upper scale limit and so should generate infinitely large corrections to the Higgs mass i.e. we go from an incredibly unlikely 1 in ~10^34 chance of the corrections giving such a light Higgs to a zero percent chance of the theory giving a light Higgs, or any Higgs with a non-infinite mass.
Obviously, if this is the case, G has nothing to do with Fermi's constant and we should not compare the two.
You are getting your 'g's and 'G's confused. In the muon g-2 experiment the 'g' is the muon's anomalous magnetic dipole moment. This is a precision test of Quantum Electrodynamics. The high order corrections to this will involve Fermi's constant (G_F) due to W and Z loops but these contributions will be incredibly small and were this any other experiment I would have said negligible but perhaps not in this case given the incredibly high precision involved. Neither of these constants have anything to do with the gravitational constant (G) nor the local acceleration due to gravity (g). So we are not comparing the two.
1 + 1 = 3, for large values of 1.
