  • The conspiracy theorists fall for the same falacy that they accuse the media and cops of doing: That it’s only interesting because the victim was a CEO.

    If this has been any other shooting, they wouldn’t be theorizing about the “message” or reasoning in his manifest. Every fucking murderer has a message or believes in a reason to do what they do.

    Until the proven killer has confessed and stated an actual message, the whole thing is entirely made up by people who want to align the story to their own interest.

    Yes sure. Code is logical stepwise. By including the “only if” it implies that other stuff is taken into account, which it isn’t at that moment in code.

    I mean, I don’t need to extend the implications of an IF statement. It already does exactly what it says.

    Anyway fuzzy logic does exist for people who want “sometimes if”. It’s useful in certain cases. I’ve only ever considered it in music production, where things very often get to the point of complexity where it makes a (sometimes) useful difference.





  • The “only” part implies exclusivity, which may be false, because other things might run the code anyway.

    IF “I can see the sun” THEN “It’s day.”

    Nothing wrong about that. However if we make it exclusive:

    IF AND ONLY IF “I can see the sun” THEN “It’s day.”

    That’s obviously wrong. I can actually not keep the day away by sitting with closed eyes in my mothers basement with the curtains shut.

    “Only if” might make sense in a legal contract, but there’s no way a piece of code can stop other pieces of code from calling the same functions.

    I’ma gonna save y’all from downloading a pdf.

    Abstract. Diamagnetic objects are repelled by magnetic fields. If the fields are strong enough, this repulsion can balance gravity, and objects levitated in this way can be held in stable equilibrium, apparently violating Earnshaw’s theorem. In fact Earnshaw’s theorem does not apply to induced magnetism, and it is possible for the total energy(gravitational + magnetic) to possess a minimum. General stability conditions are derived, and it is shown that stable zones always exist on the axis of a field with rotational symmetry, and include the inflection point of the magnitude of the field. For the field inside a solenoid, the zone is calculated in detail; if the solenoid is long, the zone is centred on the top end, and its vertical extent is about half the radius of the solenoid. The theory explains recent experiments by Geim et al, in which a variety of objects (one of which was a living frog) was levitated in a field of about 16 T. Similar ideas explain the stability of a spinning magnet (LevitronTM) above a magnetized base plate. Stable levitation of paramagnets is impossible.
