: I thought of the red being a redshift as well, but what the heck is "GREEN" then (rather than "BLUE")?

: Colors undergoing a red-shift move through the whole spectrum in sequence. Green is in the middle. Red-shifts happen when something is moving away from you, and blue-shifts happen when something is moving toward you, (although sometimes the more common term red-shift is used to describe both effects in casual context) but neither means that they thing turns red or blue. They mean that the color moves toward the red or blue side of the spectrum, from the (somewhat arbitrary) "middle" which is usually depicted as green. If the firetruck is coming toward the observer, they would be experiencing a blue-shift. If the fire truck is red, and moving very fast toward the observer, the apparent color would move toward the other end of the spectrum, but it may not be moving fast enough to get all the way to blue. Randall already did the calculations for a what if about the speeds necessary to change from red to green in an question about stoplights. --[[User:MareCrisium|MareCrisium]] ([[User talk:MareCrisium|talk]]) 00:06, 2 June 2015 (UTC) | : Colors undergoing a red-shift move through the whole spectrum in sequence.

I wonder if the reference to whether the language has a word for "firetruck" is a Sapir Whorf reference? If there's no word for firetruck, the listener (victim?) is likely to be more confused by the situation than a listener who can at least recognize what kind of vehicle is about to kill him/her (Curses! There's no sexless personal pronoun in this language!) So the reaction time of the first person is likely to be longer than that of the second person. | I wonder if the reference to whether the language has a word for "firetruck" is a Sapir Whorf reference?

:"They/them/etc." has been the accepted sexless personal pronoun for a long time (in the order of centuries), even in the singular. The only people who say you shouldn't use it for such a purpose are the same ones who say you shouldn't split an infinitive despite it having been acceptable for centuries, simply because it's impossible to split infinitives in Latin. --[[Special:Contributions/141.101.99.109|141.101.99.109]] 19:42, 29 May 2015 (UTC) | :"They/them/etc." has been the accepted sexless personal pronoun for a long time (in the order of centuries), even in the singular.

There's a whole class of psychology experiments (with both human and animal subjects) that uses reaction-time as a measure of degree of understanding in various situations. Is this effect named after a famous experimental psychologist? If so, Randall may have to issue an update to this cartoon... {{unsigned|Ribbit}} | There's a whole class of psychology experiments (with both human and animal subjects) that uses reaction-time as a measure of degree of understanding in various situations.

: Off topic, but I agree 'them' is a sufficient pronoun in this case, since you've already specified the singular 'listener'.

To the best of my knowledge, the Bernoulli effect is, in fact, responsible to the aerodynamic lift. While it is correct that most people trying to explain aerodynamic lift use an incorrect explanation, the incorrect part has nothing to do with Bernoulli, as implied by the explanation.

Is there a name for the law that states "red ones go faster"? I believe that too was referenced, but possibly not by name.
