>For a spinning projectile, this total shear stress value is larger than if it was not spinning, so by this reasoning a spinning bullet should experience more drag than a stable, non rotating bullet.

But the direction of this increase in drag should be orthogonal to the translational motion, no? If I'm right, this drag would contribute to slowing the rotation, but not to the arc of the projectile.

Dude I wasn’t trying to disparage you, but I think it’s pretty clear you were trying to argue I was “technically” right but wrong in some other more important way. You even threw in that you’re a doctor lol so am I

Language is alive and new products and techniques lead to changes. I don’t see this causing any confusion. Your example proves my point—the reason the resident would be humiliated is because it’s obvious from context that you were expecting a 12-lead.

Who is being misled? Who both understands a proper EKG is 12 leads but doesn’t also immediately realize this would be impossible with a watch?

What does “monitoring strip” mean in the context of a wrist watch? That would be very confusing.

We already know EKG is effective in diagnosing disease. This means they were able to show similar performance to existing EKGs and I think it’s kind of a big deal. I’ve gotten an FDA clearance and I can tell you believe it or not it means something and they don’t just hand them out.

E: if you think using the phrase FDA cleared is meant to be deceptive, please tell us what phrase would be more appropriate. It’s exactly the correct thing to say.
