The Code is the Design

  The Bernoulli Explanation - Another unnecessarily complicated and possibly wrong explanation taught in academia.  The Newtonian Explanation - A simple and intuitive explanation. An airflow study will probably show a net movement of air downwards behind the wing. The video above shows the NASA link, and speaks of the airflow direction change as well.

      This is just very interesting physics. The moving sand in the initial stage has the same effect as the net mass moving downwards. So the hourglass doesn't start moving up until half the sand has moved down. From another perspective, the force of the falling sand counteracts the force of buoyancy in the initial stage. But as the volume of falling sand reduces, the force too reduces and the hourglass starts moving up. Quoting from the  American Journal of Physics 85, 98 (2017);       Weight of an hourglass—Theory and experiment in quantitative comparison   "A flowing hourglass changes its weight in the course of time because of the accelerated motion of its center of mass. While this insight is not new, it is frequently said that the effect is tiny and hardly measurable. Here, we present a simple experiment that allows the monitoring of weight as a function of time, and that shows that there are different stages of the weight variati...

"During my Thiel fellowship i was told not to trust two kind of people. The first one were consultants, and the second kind were Indians who have immigrated to the US and are staying there." "Life presents you with two opportunities or two options at all times. Not four like KBC. Just two. Either a risk or regret. Whenever life presents you with either of these opportunities, taking a risk is always better than regretting not taking that risk years from now. It is okay to take a risk versus being regretful of not doing what you wanted to do." "Until you give them an opportunity to earn your trust, they never will. At the same time, there is a risk. If somebody breaks your trust, people have broken my trust, people will find you gullible and sometimes take advantage of you. I thought, if i did not trust people there was zero percent chance I'd be successful. But if I did trust people, there was at least 50% chance I'd be successful. I'd tak...

Jordan Peterson Defines True Entrepreneurship Entrepreneur are Artists. Robert Kiyosaki 2019 - The Speech That Broke The Internet!!! KEEP THEM POOR! Entrepreneurs work for free. "Integrity" || Warren Buffett || "We look for three things when we hire people. We look for intelligence, we look for initiative or energy, and we look for integrity. And if they don’t have the latter, the first two will kill you, because if you’re going to get someone without integrity, you want them lazy and dumb." Joseph Campbell — Jung and the Right and Left-hand Paths Comments from the videos given below. "Campbell looks at the two ways that myths deal with this: The Right-hand Path, staying within the Persona System; and the Left-hand Path, the dangerous, individual path of breaking out of society’s rules and expectations." "It can’t be emphasized enough that the ‘left hand path’ spoken of here is only barely survivable if you can have respect for...
