This is close to heart. To this day, when I mention Modular Scaling and Vertical Rhythm, quite a lot of developers and designers still have no clue.

I still start the stories with Mathematics and Musical Notes for product design. It is an effortless way to take “design is subjective” to being objective value.

This was magic during the early days, decades ago, and still applicable today.
