(Spoiler alert: I have not broken geometry) Suppose you have a square with side-length, L, completely surrounding a circle of radius, R, such that the edge of the circle just touches the inside of the square, like so: Those of you that remember your geometry will recall that the circumference of the circle – thatContinue reading “have i broken geometry?”

As part of a project I am working on, I needed to make some microfluidic devices. For those that aren’t familiar, these are usually chips that are made with channels, some few microns tall and wide that can handle a few microliters of fluid (hence the name: micro- fluidics). Typically, and indeed in my case,Continue reading “microfluidics 101”
