    As usual, the paper makes more sense

    Thank you for the legwork.

    I shall honour your work by ... well, RTFP-ing!.

    And ... It looks like "we told you to not do that ; this is another way of saying `don't do that`". Where "that" is "using a plaintext with predictable contents.

    And that is why, back in the early 1990s, the first Zimmerman distribution of PGP included a suggestion to use an efficient compression algorithm on a message (packet, whatever) before starting encryption ; because that hammers out the redundancy from your message and leaves less for your attacker to work on.

    OK, I may have expressed it poorly (IANA-mathematician) ; but the initial compression step makes it quite hard to differentiate the plain text from random bits. So ... "poof" to known-plaintext attacks (particularly if you include, say, a time-stamp very early in the file, to reduce predictability.

    I strongly suspect that you do not understand the meaning of "exponential" in the mathematical context appropriate for this subject.

    I gather that there may be a dilution of the meaning in slang to equate "exponentially" with "a lot". That is slang's problem.

    There are several suggestions what causes the the simultaneous sound, but AFAIK, no one has really made a solid case with measurements to back up their theory.

    Hmmm, interesting ; an area of astronomical science with which I was previously unfamiliar.

    The cited scientist seems to still be working in astronomy, if not particularly on this topic : research summary, "electrophonic" sounds, and Mongolia 1998. Doesn't seem to have updated on this since 2006.

    It does sound interesting, but I can't say that I'm terribly convinced by the "radio wave interaction" hypothesis. given that a typical meteoroid is a millimetre or so across (radius 0.05mm ; take density as 2700kg./m^3 and 7.5 km/s velocity^3) has an energy of around 300 J.

    Is that a lot of radio energy? It doesn't seem a lot to be distributed over hundreds of square km. It's obviously easily detectable by radio systems (people have been counting meteors by radio for the thick end of a century), but producing sonic effects in untuned, non-conductive "receivers" ... that strains my credulity.

    There's also a question on the efficiency of conversion of KE to radio broadcast energy.

    The "Global Electrophonic Fireball Survey" http://www.gefsproject.org/news/index.html seems to have been quiet since 2002.

    Well, that's science for you ; anyone who is sufficiently motivated to take up the baton of research will, I'm sure, be able to follow on. Until the black helicopters drag you away to Area 51 for interrogation and re-programming. (I'm sure there are conspiracy theories lurking about in the woodwork.)

    I've actually been arguing this point for the last 20 years, since about 5 years after I got my driving license (at age 24 or 25 ; I'd have to check my diary).

    Get a driving license tomorrow, and read it's expiry date of (say) 2023-08-04, on which date you no longer have a driving license. Put a different date in there for "earliest possible driving test re-sit" of (say) 2022-08-04, so that you can manage the transition reasonably.

    Pain as a method of motivation?

    Do people still believe, or at least pretend to believe, that crock of shit? All that inflicting pain does is motivate the victim to find some way of stopping the pain - telling the waterboarders what you think they want to hear in a modern pro-democratic example ; punching the games master in the face when he flogged me in examples from my own history.

    Practices have certainly varied at different times. Depending on the recruitment state of the British Navy, it was often considered bad practice to actually kill sailors while disciplining them (because you might not be able to kidnap a replacement for some time), so when the 'cat' was being applied the person would be flogged into unconsciousness, then cut down, taken to the surgeon to be treated until the surgeon considered him well enough to resume his punishment.
