  1. When capitalism goes wrong, you get this kind of industry.

  2.  @tstcikhthyss  The fact that you have to clarify showed how confusing and unwieldy the imperial system of any kind really is.

  3.  @DarkSideChess  No it is not. You are just used to fahrenheit. In Celsius, -20 is omg this is cold as hell, -10 is damn cold, 0 is freezing, 10 is fridge, 20 is nice room temp, 25 is quite warm, 30 is pretty warm, 35 is god damn hot, and 40 is WTF! There is no confusion. But I can also tell you that 40 is nice shower temp, 50 is lukewarm water, 60 you can slow cook meat, 70 and above is scalding hot, and 100 is "you make tea" boiling water.

  4.  @captbiptoe  The freezing/boiling point of water at sea level pressure is not arbitrary. It is based on a physical property of a single material that is widely found on Earth and elsewhere in the universe.

  5. In STEM, engineering is the only field that is still holding out on the imperial system. It is stupid as hell. If you are an engineer and insist on using the imperial system, you are part of the problem. The only possible advantage the imperial system has over metric is that some conversions are in certain fixed multipliers. But it only make sense if you are working in the 17th century when precision was roughly about halves, quarters, dozens, and couple of dozens. It is mindbogglingly stupid to try to divide or multiple stuff today in quadruples. I don't care whether you like your toolset to be divided in 4 inch, 1 inch, 1/2 inch, 1/4 inch, 1/16 or 1/64 inch. It is still stupid. It only looks not stupid because you grew up using it, not because it makes any sense. And you know what, if one day we do make contact with aliens, we can actually tell them how we measure stuff by indicating how we define it by fixed standards found in the universe, not by the arbitrary length of someone's foot back in the year 1098.

  6. The military and government might have adopted feudal era mentality but they are definitely not organized in feudal manner.

  7. Supersonic transport is always going to be a non-starter today and in the near future because you are sacrificing fuel efficiency, passenger capacity, maintenance costs, noise and emission pollution for one thing: speed. We are not even talking about a significant improvement of speed. Even at Mach 2, it will be faster than today's jetliner by roughly 230%, which will shave off a 4 hours off a normal 9 hours flight. It really does not sound much at all of you factor in all the sacrifices. It is not as though you are shaving off a 7 days trip down to 3 days which would be significantly on a human scale.

  8.  @sidgar1  It is only entrench because people here are stubborn. Everyone else has moved on.
