    Conservation of angular momentum L = r x p (vector product) with p = mv the linear momentum. So if L being a vector is constant so is its direction, so p (and v) being perpendicular to L implies that the movement must be constrained to a plane (perpendicular to L). It’s the same reason why the planets of the solar system lie on a single plane and not on a sphere like artificial satellites around the earth.

    It refers to the ability to locate the source of a sound. It supposes that the localization is achieved only by the difference of the time of arrival of the sound to both ears. That’s why the curve is a hyperbola, which is the set of points which distances to the foci (ears) have the same difference, so you couldn’t differentiate which of all the points in the hyperbola is the actual source (confusion). But this is too simplistic, the auditory system is much more sophisticated and the source can be localized by other means.

  • Amazing but more usual that one might think, it’s the same anger you can see in people that identity themselves with some other fictions like religion, nationalism, football teams, ideology, race, etc. When watching a movie you kind of temporarily turn off your disbelief to experience joy, sadness, anxiety etc but when the movie is over the healthy behavior is the recognition that everything was an acting. But with the fictions that I just described somehow the disbelief is never turned on, the critical thinking is canceled.

    With all the information available at your fingertips being ignorant is a choice.

    “this parallel financial system can also serve a tangible social good, offering an onramp to the financial system for people who would otherwise be left out. In countries where the vast majority of the population is unbanked, national currencies are no longer a safe store of value, remittances comprise a hefty portion of GDP, and international sanctions complicate connections to the global economy, a virtual currency that doesn’t require an intermediary to approve transactions can be a vital lifeline for survival”
