  • From your source:

    {The upper flow is faster and from Bernoulli’s equation the pressure is lower. The difference in pressure across the airfoil produces the lift.} As we have seen in Experiment #1, this part of the theory is correct.

    Sure, it might be more complicated and there are other forces at play. Also, top and bottom air molecules may not reach the backside of an airfoil at the exact same time, but that doesn’t diminish the effects of this pressure differential on lifting force.


  • That lift explanation is innacurate/incomplete. While there may be some equal and opposite forces depending on the angle of attack, the primary reason for lift is due to Bernoulli’s Principle. Airfoils have a rounded upper surface with a longer path for air to take, relative to the underside. This requires air to move at a higher velocity over the top, and since A1 x V1 x P1 = A2 x V2 x P2, pressure over the airfoil decreases. It is this pressure differential that creates lift.

    In regards to aircraft, Newton’s third law of motion applies to thrust from a propeller or jet engine.



  • I always prefer to sit unless I’m in a huge hurry. It’s called a restroom for a reason. I’m going to take a break, browse Lemmy or something, and otherwise “rest”. I’ll return to work when I’m ready.

    What really pisses me off is when I hear someone enter another stall to take a standing piss. They rarely put the seat up and always get pee all over everything. If you’re going to stand, use a urinal. There’s nothing more pathetic than being afraid to whip your dick out beside your fellow man, and instead, choose to piss on the place where others want to take a sit.

    “I dare you”

    How could you think this possibly warrants a dare? Do you really think people are this confrontational in real life? When traveling in other countries, I have only had positive interactions when attempting to find any common ground with locals. In this case, the worst thing that could happen is you share a laugh and they offer for you to try real local cuisine.

    Kind of related, the duck tongue and chicken’s foot I had earlier this year in Malaysia wasn’t that bad.

    If by common knowledge, you mean that a significant portion of the population believes it, I’m not sure how reliable that evidence that is. People will believe a whole lot of strange stuff.

    On topic, even the first paragraph of the Wikipedia page states that it was “popularized by cooks from India living in Great Britain”. Regardless of where it was first created, this is clearly the product of Indian immigrants. I don’t believe their heritage should be ignored just because they moved. Although, I don’t want it to sound like I believe in a 100% black and white distinction here. It’s clearly a fusion dish with British influences. The original chicken tikka was a lot dryer and the “masala” sauce was added to make the dish creamier to appeal to British tastes.

    However, I don’t go around claiming General Tso’s chicken isn’t Chinese food, just because it was first made in New York; or that the chimichanga isn’t Mexican food, just because it was originally made in Arizona; or that a Cuban sandwich isn’t Cuban, just because it was first made in Florida. These dishes wouldn’t exist without the immigrants who modified their cultural recipes to adapt to a new environment.

    To me, chicken tikka malala is an Indian dish with British influences.

    E: Tao to Tso.
