Nicholas Christakis:

Halfway through one of my lectures [at the Kyiv School of Economics], the air-raid siren went off. We relocated to this old Soviet-era building and went two or three stories underground into a bomb shelter with huge blast doors. We continued the class. And the students were beaming. It lifted me up to see their enthusiasm, their commitment. It also reinforced something very deep about our common humanity, which is that we humans like to learn, even in a time of war.

I also couldn’t help but notice that these students had a very different understanding of safety than American students. When American students want a safe space, it’s because they don’t want to hear threatening ideas. For Ukrainian students, safety means learning without bombs falling.
