  1. Reminds me of a report I saw somewhere about electron microscopes that didn't work at a fairly high altitude. The manufacturer had not tested under low pressure conditions.

  2. It can be used the other way around too; pressure cookers can go to higher temperatures, and cook food faster.

  3. Discussing why a reading didn't match expectations is not bad at all. This is the start of many good scientific inquiries; discoveries that make you go "huh". They were discussing variables they had not controlled for. I'd guess the big one is that they're looking at samples days apart, with weather affecting pressure to a similar degree. If they recorded air pressure and temperature as well as altitude, this hypothesis could be tested with existing data. An example of bad science would be assuming a measurement was in error and discarding it instead of highlighting it.

  4. Most of the bacteria we'd worry about can't handle 65 degrees C (the big one is legionella, which is why hot water should not drop below 50 degrees). Also, boiling itself kills them as they contain water. It's recommended to boil longer at lower pressures, as it's gradual anyway.

  5. The next recommendation in my list is an episode from Dylan Beattie's series "the history of software in three letter acronyms", "B is for BBC". I think that's a good choice.

  6. They did. It's the part left of the hyphen.

  7. May I recommend AlphaPhoenix's video "Boil Water at Room Temperature with 50 ft. of Hose and a Stairwell"? There's bound to be a few other good ones on the subject as well.

  8. It could be for relating to flight levels, which are given in hectofeet.

  9. AlphaPhoenix has a nice video where he demonstrated boiling water by pulling it up a straw (long vertical hose). It's titled "Boil Water at Room Temperature with 50 ft. of Hose and a Stairwell." He discusses the physics of it at some length.
