I did not say you can't measure a snowflake. I said snowflakes. As in, you can't measure how many snowflakes there were yesterday.Excuse me, but one CAN measure the mass of a snowflake. Take a large sample of snowflakes, and one gets an average mass for snowflakes...the larger the sample the closer one comes to a true average.
One can then take the mass of a pile of snowflake, divide by the average mass, and one gets a very close measure of the number of snowflakes in the pile.
No, not immeasurable.
Your thinking is limited.
An average mass and a "very close" isn't a precise measurement.
