    You got it. Or will be getting it. Or will have gotten it soon. @Kittypaws is correct essentially. The Earths Magnetic field is the answer to that. They have an organ/area in their brain that's attuned to the field/lines that keeps them flying true. I actually knew this before I went to find proof for you because you're so durn hard headed about things sometimes. I quote"
    Vision-Based Magnetoreception
    One of the more complicated theories to explain avian migration involves bird species’ ability to detect the magnetic fields of the Earth, and subsequently follow those fields to their ultimate destination. This ability to use “invisible” waves was hard for some ornithologists to swallow, but it was proposed that some bird beaks contain magnetic particles that act as a compass. Recently, this theory has fallen out of fashion, replaced by the theory of vision-based magnetoreception.

    The concept of vision-based magnetoreception means that birds can “see” magnetic fields and align themselves with the direction of the field they want to travel. If a bird is migrating south, it will align with a south-facing magnetic field and be on its way. Experiments in laboratories have actually generated artificial “magnetic south”, and birds moved in that direction."

    C'mon now @neilold that's high school stuff :picard:

    Another easily answered one :picard:. Do not English schools teach physics? ;-)

    I refer you to Sir Issac Newton and his 3 Laws of Motion. Also Mr. Daniel Bernoulli and his work in fluid dynamics.

    http://www.courses.netc.navy.mil/courses/14014A/14014A_ch3.pdf

    https://en.wikipedia.org/wiki/Bernoulli's_principle

    In a nutshell, just because your speed is decreased it does not cancel out the lift from the medium it is traveling in. Your drag is also increased by the same rate and your forward rate of Momentum is something that must be factored in. Lift : L = Cl * A * .5 * r * V^2 / Drag : D = .5 * Cd * r * V^2 * A / Momentum : p = m • v

    You're welcome. :thanks:

    Idly Pondering ........... If you evolved in a world of liquid helium (−269 °C about 4 K or −452.2 °F) what would it take to be "cold"?

    you know, you can actually throw liquid nitrogen onto your face, and it won't dissolve your skin. It just splashes and bounces off, it can't really stick to it, as such, unless its contained in something, the molecules in it are quite strange. So thoughts of it being chucked over someone, and them insta freezing are just fantasy. You can also fill a balloon with it, and then smash the balloon against you, and again you won't be soaked in it, the balloon and the liquid nitrogen just kinda dissolve with the bang

    Believe it or not I did know this. In fact just watched a youtube video to that effect but note that the key word in this is time. Too long and it will most definitely freeze your skin. The time frame is NOT very long either.

    Then I would advise staying well clear of Liquid Nitrogen and chill on the BEACH instead!
