Physicists like to ignore things. In some cases, we may neglect gravity or assume that the temperature is zero degrees Kelvin — colder than any known substance in the universe. And friction is almost comically absent in most models, despite the fact that a world without it would be utterly uninhabitable (this is nicely illustrated in cartoon form here: https://xkcd.com/669/).

I'm an experimentalist studying the physics of evaporating droplets. Generally speaking, I'm interested in how simple systems and ideas in soft matter can help us learn about more complicated phenomena.
