593b: Fill & Download for Free

Ok so first let’s start with examples of founder-controlled boards:Google, Amazon, Facebook, Zynga, SnapchatPretty impressive list right?PROS:Founder-controlled boards allow the founders to make decisions that are in line with their vision even when it goes against the interest of their investors or other stakeholders. For example, Facebook turned down an acquisition offer by Yahoo for $1B. Facebook is now worth $593B. Snapchat turned down a $3B acquisition offer by Facebook and is now worth $22B.CONS:First of all, founder-controlled boards are difficult to attain in the first place. This is because most investors won’t agree to full founder control when they invest their capital into the company. The only reason Google, Facebook, and others were able to keep founder-control is because they had extremely strong growth and metrics. Investors have less control over the operating team. If the investors in the company decided that the company was heading in the wrong direction they wouldn’t have the ability to change its course or put in place a new management team.At the end of the day if a founder has an extremely ambitious vision then the only way to build that is with a founder-controlled board.

“Why does America spend more money on defense and less money on education; it makes no sense?”I hate to be cliche, but before you ask why, ask if.Government Spending DetailsIn 2016, the United States spent $952B on education and $593B on military defense. Thus, the United States spends 61% more on education than on defense.In exchange for the nearly $1 trillion in education spending, the United States largely restricts its expenditures to educating fellow Americans, although there are a significant minority of undocumented immigrants in that number as well.In stark contrast, especially with regard to the Navy, the United States polices most of the planet - most of the benefits of this spending go to other countries, not to the USA.

2 key reasons:1 - Low bypass vs high bypass engines - Similar thrust level engines have radically different front sections.Olympus 593B produces under 35000lb of thrust with 40 inch fan diameterCompare that with the 737MAX8 engines that produce <30000lb of thrust and have a 69 inch fan diameter2 - Supersonic vs subsonic aerodynamics - On supersonic you need to have as little as possible surface area.A separate, individual cowling per engine gives the best aerodynamics for subsonic flight, but would bad in the supersonic regime.Aerodynamics is super complicated. I’m not equipped to give out a proper explanation, but it goes a lot into those 2 topics.High bypass engines are super bad in supersonic flight, because they generate too much drag from their large frontal section.Compare other supersonic aircraft (fighters in general), specially fighters from the same generation (pre 1970s).Also the Concorde was designed pre CFD, pre CAD/CAM, pre computer simulations. It was a very different reality back then.
