Biological modeling is organized inquiry, but how should we think about the process?
My new paper in #EcologyLetters argues that we should model like experimentalists: define treatments, measure responses, validate, perturb, repeat.

Do you agree?

Ever since I made a video about Fourier Transforms, one of the most requested topics on the channel has been its close cousin, the Laplace Transform.
I've been having a lot of fun animating a mini-series about this topic, and the main part is now out.
