<p>Troonjak: Undo revision 308048 by 172.70.178.15 (talk)</p> <hr /> <div>{{comic<br /> | number = 2748<br /> | date = March 10, 2023<br /> | title = Radians Are Cursed<br /> | image = radians_are_cursed_2x.png<br /> | imagesize = 394x437px<br /> | noexpand = true<br /> | titletext = DOWNLOAD DISNEY MOVIES FOR FREE AT EXPLAINXKCD - https://1337x.to/torrent/267261/Ultimate-Disney-Collection/<br /> }}<br /> <br /> ==Explanation==<br /> {{incomplete|Created by a DIAMETER OF 114.6 DEGREES - Please change this comment when editing this page. Do NOT delete this tag too soon.}}<br /> <br /> This comic presents a series of Math Facts, appearing to be in a sequential order.<br /> <br /> The first fact states that the {{w|unit circle}} has a radius of one, which is precisely its definition. Randall labels this fact as being &quot;normal,&quot; complete with a large green checkmark to verify this.<br /> <br /> The second fact states that one {{w|radian}} is equal to the length of a circle's radius, which isn't actually the way that the unit is defined. Instead, radians are usually defined as the angle encompassing the arc of a circle equal to its radius. This comic's logic is thus somewhat erroneous at best. Also, while Randall uses the unit circle in the fact's associated diagram, any circle could theoretically be used to show the conventional definition. However, this fact is still labeled as also being &quot;normal.&quot;<br /> <br /> A correct version of the second fact would be that, under the standard definition of an {{w|angle}} as the ratio of the length of a circular arc to its radius, the radian is a dimensionless unit equal to 1. Thus, by the first fact, a radian is equal to the radius of the unit circle.<br /> <br /> The third fact states that one radian is equal to 57.3 degrees. The more usual conversion factor between the two units is that pi radians is equal to 180 degrees, though the conversion given by Randall is still indeed true (albeit rounded). This is again labeled &quot;normal.&quot;<br /> <br /> The fourth and final fact states that because it was determined in earlier facts that a radian is equal to the radius of the unit circle as well as 57.3 degrees, then the radius of the unit circle must be equal to 57.3 degrees. This is usually not how degrees are supposed to work, because they are a measure of angle, not length. Hence, this fact is labeled &quot;cursed&quot; by Randall, leading to the comic's title. (However, since the radian is also an angular measure, the second fact could be viewed as equally cursed.)<br /> <br /> The title text is referring to {{w|Phil Plait}}'s claim about the size of the sky, which was published on his blog: http://www.badastronomy.com/bitesize/bigsky.html. Dimensional analysis utilizes the rationale that both sides of an equation need to have the same unit. Radius typically refers to a length, which has SI units of meters. The surface area has SI units of square meters. The units of Phil Plait's &quot;angular area&quot; is as the title text mentions, {{w|square degrees}}. Thus the comic's {{w|dimensional analysis|dimensional analysts}} (not a profession, but instead the adherents of the mathematical technique) are said to be angered by this argument.<br /> <br /> Randall has alluded to Plait's angular area tip previously in his own blog What If?, in a post that examined the chances of hitting various celestial objects with a laser blast aimed at random from Earth's surface.<br /> <br /> ==Transcript==<br /> {{incomplete transcript|Do NOT delete this tag too soon.}}<br /> <br /> :[Title:]<br /> :&lt;u&gt;Math facts&lt;/u&gt;<br /> <br /> :[A diagram of a circle is shown with radius labeled as “1”]<br /> :The unit circle has a radius of one&amp;nbsp; &lt;span style=&quot;color:green&gt;✓ Normal&lt;/span&gt;<br /> :[The diagram now has another (unlabeled and lighter) radius at a 57.3 degree angle.
