Adam Savage Has an Epiphany About the Science of Measurement

One of my favorite things on Adam Savage’s Tested channel is when he answers viewers’ questions, or even better yet, when he just enthusiastically riffs on a subject.

In this video, Adam was compelled to turn the camera on and share when he had a real ah-ha moment about the nature of precision measurement and the tools we use to try and achieve accuracy in measuring. As he says in the video, “all measurement is a compromise of circumstance” and “there’s no such thing as an actual measurement.” Watch the video to unpack these ideas further.

Over the course of the video, he talks about ceramic and metal reference gauge blocks and other extremely high-precision measuring tools.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
