The Physics Of Sports That "Defy Physics"

I love this article, and it is about time someone writes something like this.

Chad Orzel has a nice article explaining why the often-claimed event in sports that "defy physics" actually happened BECAUSE of physics.

Of course, as several physicists grumbled on Twitter this morning, “defied physics” is a silly way to describe these plays. These aren’t happening in defiance of physics, they’re happening because of physics. Physics is absolute and universal, and never defied– the challenge and the fun of these plays is to explain why and how these seemingly impossible shots are consistent with known physics.

What is being "defied" is one's understanding and expectations of what would happen and what looked seemingly impossible to happen. This is DIFFERENT than discovering  something that "defies physics", and that is what many people, especially sports writers and TV heads do not seem to understand. The fact that these people often lack any deep understanding of basic physics, but somehow seem to clearly know when something they don't understand well is being "defied", appears to be lost in all of this. It is like me, having never visited France or know much about the French people, making a claim that something isn't consistent with that country or people simply based on what I understand from watching TV.

I wish they stop using the phrase "defy physics" in situation like this the same way I wish reporters stop using the phrase "rate of speed" when they actually just mean "speed"!
