> Cells are physical objects

This might sound trivial, but in me sparks a much larger point: which kinds of experimental designs and tests might we miss when engaging in a special science? In establishing dedicated methods I think it's highly likely for there to be low-hanging fruits of experimental setups not considered due to prevalence of these very specific frameworks.

Very cool. I wonder how the accuracy of weighing a single cell would compare to counting a huge number of cells (let's say 10^9) and doing a bulk weight measurement. The problem would shift to being able to accurately count cells, and being able to exclude the effects of liquid trapped in between the cells.

Asimov really is a breath of fresh air. Love their content

> A typical kitchen scale has a sensitivity of 0.1 grams

As someone who's been looking for a good kitchen scale, your typical kitchen scale is actually precise to then nearest gram at best, and in terms of precision it's probably not very precise at all. 0.1g is rare, and these usually cost more, especially if they're actually reliable.

Some surprising science fact that many people don't know, an animal egg (chicken, birds, etc) is a single cell, so there's a huge variability in the weight of a cell.
