This article, while interesting, unfortunately describes the Equal Transit-Time Fallacy [1]. http://en.wikipedia.org/wiki/Lift_(force)#False_explanation_...


Does it? I only see talk of accelerated flow on top of the wing leading to reduced pressure, nothing about arriving at the trailing edge at a certain time.


Right, and for what reason would the flow atop the wing be faster than below?

The equal-time assumption is what leads to the idea that flow on top is faster (and therefore, pressure is lower).


This post warrants a little public shaming: http://xkcd.com/1138/


If you download the latest build this problem was fixed for me. http://nightlies.videolan.org/build/macosx-intel/?C=M;O=D


Math is not simply following instructions like a recipe. Maybe if you put your cookbook through a paper shredder then what the author says may apply... I get the author's Maddox like style and all, but such things do not belong on HN.


I disagree with this post. There are professors out there who do in fact teach code style in a very hands on and personal manner. Chris Riesbeck [1] at Northwestern University has made a great system to teach good coding practices in a number of languages. Many of my fellow alumni have learned good coding practices from him. Its an inside joke to talk about "Riesbeck crying" when messy code is written.

The first line says it all: "That's how The Associated Press describes the way scientists are describing..." That's a lot of description without much proof.


Too bad what he suggests requires skills that most people don't have, at least not yet. To achieve this utopic vision we need to drastically change our education from being job-driven towards being production-driven (e.g. teaching more practical programming to younger audiences, encouraging self-motivated thinking rather than homework burn-out). This is not an easy task.

I like his vision but I fail to see how it can work out. The reality is that people are lazy. While making stuff because you want to is awesome, most people would rather sit on the couch and consume. Its because they have to feed themselves and buy nice TVs that they go to work in the morning.


how do you know that the person your talking to is indeed the person you sent the link to?


Maybe using a passphrase?

thanks!


Many of my friends doing phds in math are terrible at mental arithmetic. Higher level Mathematics does not have much to do with how fast you can calculate tip in your head.
