A small drawing made in my phone (with one finger). I used to apps: Sketchbook and ASKetch.

enjoying the process of the smallness grow.

What is the smallest unit of measure?

The smallest unit of distance that we can actually measure is an Angstrom – this is 10 million times smaller than a millimetre. There are even smaller units than this, a femtometer (also known as a fermi) is 100,000 times smaller, and is about the size of an atomic nucleus.

Of course, distance is not the only unit of measurement. It is thought that a unit known as Planck time is the smallest measurement of time that will be possible. It is roughly equal to 10^−43 seconds.
