So nine weeks ago, in what seems like another life, we started this class by stepping out into a dark field outside of Athens, looking up at the dots that we saw in the sky, wondering what they were. And we started out by thinking what Aristotle would tell us about this. And over these 9 weeks, we have followed in the footsteps of many brilliant, creative individuals, and I think we have, it's fair to say, that that has taken us to places Aristotle would not have dreamed of. I hope that you have enjoyed the ride. It's been intense. I've certainly enjoyed sharing it with you, and I hope, my main intent has been to give you a sense of the splendor, the grandeur of this endeavor of trying to understand the universe. Why it is so beautiful, why it is so valuable, why it's so much fun, and why it actually makes looking up at the stars even better than it would be otherwise. Like many things in this class, the conjunction of Jupiter and the moon at the beginning of the class was unplanned, and like many things in the class, it worked out quite well. And we have surprisingly another conjunction, or almost conjunction of Jupiter and moon today. And so this seem like a fitting time to end the class. Thank you very much for the time and attention you've paid, put into it.
