That was my first thought as well. They just made their “particle” really big. So maybe if a particle is big enough, you can measure it’s position without appearing to change its velocity.

But, hey. I got my degree from Faber College. So what do I know?

Valid, but, I shall wait to have my mind changed! Then again, all science books should be written in pencil so that changes can be easily made.

You have the essence of it.

You can measure the position and momentum simultaneously; but the product of the uncertainties in each measurement, must be on the order of Planck's constant or greater.
