There's a difference between saying this is how wings generate lift and this is the only factor in the equation. On top of which angle of attack is not defined by the zero lift angle. that being said, every scrap of airfoil data I've ever seen shows a proportional relationship between (angle of attack - zero lift angle of attack) and CL (and by extension lift). Is that everything a professional needs to know about aerodynamics? Far from it. Is it an adequate explanation for laypeople? As far as I'm concerned, yes.--Someguy[[Special:Contributions/173.245.54.156|173.245.54.156]] 20:57, 29 May 2015 (UTC) | There's a difference between saying this is how wings generate lift and this is the only factor in the equation.

− | "The Peltzman effect refers to how regulations intended to increase safety are ineffective or counterproductive. This is likely referenced by the observer responding to a dangerous situation more slowly if the language he is warned in has a word describing the object he's in danger from ("firefighter") than if the language didn't." The comic states that the person reacts more *quickly* if the language has a word for firefighter... | + | "The Peltzman effect refers to how regulations intended to increase safety are ineffective or counterproductive.

: I think it's actually about how the firefighter has gotten himself into a dangerous situation due to the feeling of safety he has from being in a modern firetruck, since a major case of the Peltzman effect is that increased car safety leads us to drive at higher speeds. The innocent pedestrian is less safe because the firefighter is driving more recklessly.
