OK. This is far and away my favorite Science Faux Pas I have seen. I cut this out of some magazine many years ago and posted it on my door in college, grad. school and in my previous job, so it is a little beat up. But you got to hand it to Mathey-Tissot - promoting a precision watch with "Velocity equals mass x acceleration (V = MA)." Must be one heck of an interesting mechanism inside that watch.
