To import natural gas, you either need pipelines connected to your supplier, or a seaport capable of deliquifying natural gas. Of course, your supplier needs to have seaports capable of liquifying natural gas for transport.
LNG Terminals

There are three plants in the Americas-- Atlantic, in Trinidad-Tobago. Kenai, in Alaska. and Peru. A further plant is being built in Louisiana, Cheniere Sabine, Pass which is currently boasting of its expansion to a bi directional facility, meaning of course, that it currently only has facilities for importing gas, not exporting it

So, not quite fungible. Not nearly as much as petroleum.

I'm not sure why Apple needs to enhance shareholder value. Apple hasn't raised capital on the markets for years. Apple needs to be profitable, Apple needs to be an attractive platform for developers. Apple needs to be perceived, by its customers, as qualitatively superior to Android and Windows. But enhancing shareholder value should be a side effect of those more important goals, not a goal in itself.

To be fair, Theresa May is primarily concerned that her xenophobic policies will be undermined by Scottish independence.

"Buried deep in Alex Salmond's white paper is the admission that, just like the last Labour government, a separate Scotland would pursue a looser immigration policy.

  "That would undermine the work we have done since 2010, and the continuing UK could not allow Scotland to become a convenient landing point for migration into the United Kingdom.

If Scotland votes No, all her hard work will go down the drain when Labour eventually wins a majority
If Scotland votes Yes, the Tories will be entrenched for some time to come, and the only real threat to her work will be Scotland opting for a less Conservative immigration policy.

The programmers need to design a digital Bretton Woods system and enforce a stable exchange rate. For instance, the value of one eMark could be pegged at one five hundredth of a bitcoin, and the various central banks would be obligated to buy and sell bitcoins and emarks at that rate. That way, a miner wouldn't have to worry about backing the wrong computations.

Guess the poor guy didn't know about having to send his bribes in to stay in the Great Leader's good graces.

That would be how it works in Russia, but in the United States, polluters can't (and shouldn't be able to) bribe themselves out of jail.

From Aviation Week

It wasn’t hard for the Russians to assess the JSF’s stealth performance. By 1995, everyone knew that shape was the major driver of RCS, with materials being used to control local scattering phenomena. As the JSF’s target service entry date arrived, so did the Russian answer, and it was on display at the MAKS air show, held in Moscow in August.

The 55Zh6ME radar complex addresses many of the limitations of the old VHF radars. Although you see three radars—stepping down from VHF (metric) to L-band (decametric) and S-band (centimetric)—the Russians call them modules of an integrated radar system. Each unit is fitted with the Orientir satellite-navigation system, which provides a very accurate location and north reference. That should make it possible to provide sensor fusion—ensuring that when two or more of the radar units detect a target, it will show up as one in the control center.

The VHF part of the system (see photo) has a P-14-sized, 30-meter-wide antenna, but it folds onto an 8 x 8 truck. The antenna has an active, electronically scanned array, so if it gets a hit on a faint target, the array can dwell on it as the antenna rotates (or swings back and forth for a sector search). At the same time, it will cue its L-band and S-band sisters to focus on the target area like searchlight beams.
Some commentators will look at the Russian brochures, note that the reference ranges are against targets with an RCS of one square meter and observe that stealth aircraft have a far smaller RCS, which they do—in centimetric bands. Giving what was probably the least provocative answer under the circumstances, a Russian engineer notes that the Chinese DF-15 short-range ballistic missile has a 0.002 m2 RCS in X-band, but is a very non-stealthy 0.6 m2 in VHF.

Two exhibitors at MAKS were showing passive RF tracking systems. They are intended to exploit active emissions from the target but do not discriminate. Scattered energy from a radar will work just as well. The U.S. Air Force does have a modern facility for testing such bistatic radar signatures, but it was commissioned after the JSF was designed.

Of course, this sort of analysis relies on unclassified data. As the author himself states.

There may be a universe where it is smart to give your adversaries (or their armorer) 25 years’ notice of exactly how you plan to render their defenses obsolete. We just don’t live there.

instead, we live in a world where one must have faith that a trillion dollar weapons program has been designed correctly. How comforting.

From Top Secret America: the rise of the surveilance state

As important to a man's self image as the power of his car's engine or his motorcycle's rumble, SCIF size had become a symbol of status. "In DC, everyone talks SCIF, SCIF, SCIF," said Bruce Paquin, owner of a construction company that builds SCIFs for the government and private corporations. "They've got the penis envy thing going. You can't be a big boy unless you're a three letter agency and you have a big SCIF.

but how could they possible determine how much mass in each galaxy wouldn't be seen by using light within the bounds of the visible spectrum?

Such "dark matter" would show up on Xrays infrared or radio, so that's not a problem. If, however, the "dark matter" does not interact with electromagnetism, but only with gravity and the weak force, (which would be an extremely odd, and frankly, a not very believable aspect of cosmology) things would get a bit tricky.
