It's been way too long since I sent out the last issue. I had planned to send one out February 24th, but with Russia's invasion of Ukraine, I got distracted. Switzerland now has over 50,000 Ukrainian refugees. I've been impressed by how the university has worked on integrating Ukrainian students into our curriculum. The situation generally is heartbreaking, of course. Five million Ukrainians have left their country, another seven million are displaced within Ukraine.I created these postcards to call attention to the crisis. If you're inspired to make a donation to a charity that helps Ukrainian refugees, please do. Let me know and I'd be happy to send you some of these cards in postal mail, just send me your mailing address.
