This weekend, I went to Kobe Oji Zoo. I was with my youngest nephew. He loves airplanes and the Shinkansen (bullet trains). While watching penguins swimming quickly before us, I explained fluid dynamics, which I had just studied. He found something in common between penguins and airplanes. He learned what streamlines were like. He had no end of questions, saying “Tell me more! Tell me why airplanes can fly!”
So today, I studied the mechanism of jet engines. I was thrilled! I can’t wait to see him and explain it!
