What do you mean by “everything is rubber”?

Everything is flexible, to some degree. Drop a feather onto a pool table, and the weight of that feather will bend the slate of the pool table. It's a tiny, tiny, TINY amount, but given appropriately sensitive equipment, you will find that there's a deflection.
When you're measuring down to 3, 4, or especially 5 decimal places, even the heat of your breath can distort a part a measureable amount.
Robin Renzetti has a great demonstration of this, if you're curious. Skip to 31:00 for the relevant part.

For those who watch the video: If you skip to 31:00, you need to watch to 35:49, to see why he's doing this testing on his carpet? :)

Adam Savage has some interesting discussions about his journey towards precision. Pask has a similar kind of arc as well on his channel. The hallmark of craftsmen is that their tastes become more and more exacting over time. The tools needed to accomplish that become more and more specialized and beautiful too.

I've enjoyed Adam Savage's journey. Wild to see someone I admire so much, have the same kinds of struggles and learning experiences that I have.
