In Sherlock: Study in Pink how does the choice of bottles work?

This is covered in the episode, Holmes mentions it to the cabbie and the cabbie replies something like:

Four games and four wins, that's not random

If you want an excellent, explained example of this in action - watch The Princess Bride:

The man in black's intelligence test. He provides two vials, one of which is poisoned.

Vizzini explains his chain of thought thus expressing how he feels that the placement of the poisons is not random but is a psychological trick. In the same way the taxi driver feels that there is psychology in the way he plays his 'game' and that it is not random - whether either if them are right or wrong is not the point, the point is that they feel there is more to it than random chance

Note: the twist in the Princess Bride's version about immunities is not relevant to the Holmes's version. I only included this as it explained the chain of thought as to which glass should be drunk from.

What inspired Elaine's dance moves?

In one of the most memorable jokes from Seinfeld, Elaine dances at a company party in "The Little Kicks" (S8E4), and again briefly in "The Slicer" (S9E7).

Has Julia Louis-Dreyfus ever discussed how the dance came about? Was there input from Larry David or any of the cast members? What inspired her dance moves?

star trek - How exactly did the prisoners escape the Jem'hadar prisoner camp?

DS9 "By Inferno's Light":

MARTOK: He wired the message and the transmission coordinates directly
into the system circuitry. That way all he had to do was connect the
transmitter to the power grid and let it run.

WORF: Could the coordinates and the message be changed?

GARAK: You're planning to contact the runabout.

WORF: We could activate the transporter and beam ourselves onto the
ship.

BASHIR: And run like hell.

And then a bit later in the episode:

GARAK: Doctor, would you keep the noise down? I'm trying to work in
here.

BASHIR [OC]: Garak, how many translator circuits have you got left?

[Barracks]

GARAK [OC]: Three.

BASHIR: Well, work fast, because pretty soon we're going to be up to
our necks in Jem'Hadar.

Next scene:

KAT'IKA: I yield. I cannot defeat this Klingon. All I can do is kill
him, and that no longer holds my interest.

DEYOS: Shoot them both.

[Crawlspace]

GARAK: Got it.

[Internment centre]

(Just as Ikat'ika is killed, our heroes are beamed out.)

I loved the episode but was really confused by this aspect of it.

I don't understand how they escaped. They do not have communicators on. I assume there's gotta be some kind of shielding around the prison. There's a runabout floating in space close enough to transport that's unattended. Garek is being asked to send a coded message of some sort to the runabout to transport more people out then transported down, without communicators attached to them, in different areas.

What kind of message did Garek send to affect that kind of transport? How did a runabout sit close enough to the prison to be in transporter range, but not be detected? How did they flee Dominion space in a runabout without getting chased down after the transport?

What is the current state of gravity in the vacuum of space?

Newton's third law is that if a body A exerts a force on body B, then body B exerts an equal (in magnitude) and opposite (in direction) force on body A. In Newtonian gravity when body A exerts a gravitational force on body B, then body B exerts an equal gravitational force on body A. As both forces are attractive they have opposite directions.

General relativity doesn't treat gravity as a force, but Newton's third law can be demonstrated in the Newtonian limit of GR.

In big bang cosmology the initial expansion is not due to gravity or any other "force", rather it comes from the initial conditions of the Universe. Matter and radiation have positive energy density and non-negative pressure which both contribute to their gravity which acts to slow down the rate of expansion (the Hubble parameter). However it has been demonstrated that the Universe's rate of expansion is in fact increasing which means that there must exist some form of dark energy which has a negative pressure which is large enough in proportion to its (positive) energy density to accelerate the expansion of the Universe.

star wars - How many systems are there in the Galaxy far far away?

3.2 billion habitable star systems

According to Wookieepedia:

Factoring in the output of heat and light needed for an advanced civilization to form, there were 7.1 billion truly habitable stars within the Galaxy, and about 3.2 billion habitable star systems. However, it was estimated that about one billion of those systems were actually populated.

game of thrones - Who is the Lord of Storm's End?

Beware, spoilers...

In the books (as of A Dance of Dragons):

Stannis Baratheon is still alive. He would be succeeded by Shireen Baratheon.

In the show (as of Season 6 Episode 4):
Tommen would have the strongest claim to Storm's End by two different means.

1) As the 'heir' of Robert Baratheon. This would be problematic (If widely known and proven) since he is a bastard born of incest rather than Robert's true born son.

2) As the king.

The entire, legitimate house Baratheon has been wiped out and bastards (such as Gendry) cannot inherit.

In this case the lands and holdings would pass to the crown to be kept or handed out at will.

the force awakens - Has it been officially announced that Star Wars Ep VII will be in 3D?

3D has become ubiquitous for most blockbusters, and next month’s Star Wars: The Force Awakens is no exception. Between 2D and 3D, 70MM IMAX and standard, there are a multitude of different ways to be able to experience the movie.

source: Cinema Blend

So there are three versions of the new Star Wars movie: 2D, standard 3D, and 70MM IMAX 3D

According to slashfilm.com, Director J.J. Abrams only shot one sequence in The Force Awakens on 70mm IMAX film stock, the rest was shot on 35mm film, and in an interview he claimed

When I was watching the reels in 3D, there were a number of shots — and I know this sounds insane — that I hadn’t understood in the three-dimensional space quite the way I did when I saw them in 3D. I actually felt that there were things that were playing better in 3D. I had never felt that before. And if people have access to a theater that has laser projection, it is shockingly better.

The following images illustrate the differences between the normal 3D format and the IMAX 70MM.

Standard Widescreen

70MM IMAX

The website Tech Insider recommends fans to watch the 3D version, but only if the movie theater accommodates the 70MM IMAX version

Unless you're seeing this on a true IMAX screen and in 70mm (one of these theaters), go with the 2D tickets.

Wikipedia informs that the film was released in N. America on December 18, 2015 in 4,134 theatres of which....

... 3,300 were 3D locations, a record 392 IMAX screens (13 of which are 70mm), 451 premium large format screens, 146 D-Box locations, as well as releasing in the Dolby Vision format (High dynamic range, Rec. 2020 color) in Dolby Cinema. Worldwide, it will be released across 940 IMAX theaters, a new record. On December 18, 2015, the film began playing on every IMAX screen in North America for four straight weeks up to January 14, 2016.
