The Brain Scoop:
500 million years ago a collision between two asteroids threw one of them out of its rotation in the belt between Jupiter and Mars. Within a few tens of thousands of years the fragments of that meteor fell to earth and sank to the bottom of an ancient sea in modern-day Sweden. Over millions of years the mineralization process replaced many of the original elements in the meteorite, but thanks to some key identifying chemical markers our geologists and meteoriticists were able to determine that these specimens, excavated from a limestone quarry, are fragments of that ancient asteroid collision.
The craziest part of all of this? Those fragments are still falling on earth today - in fact, one was found here in Chicago a few years ago, and after analysis it was matched to one of the fossilized fragments from Sweden.
Separated by unthinkable distances in space and more than 500 million years, they’re reunited together again right here at The Field Museum. Now tell me that isn’t a story of star-crossed lovers.
I love that Emily takes viewers not only behind-the-scenes but documents and explains how the scientific research is accomplished.
The physics flows come faster than furious photons in this one. Features none other than Weird Al as Isaac Newton! And a special cameo from Jurassic 5’s Chali 2na as none other than Neil deGrasse Tyson.
(Hint: We did, all of us, because this is awesome)
Neil deGrasse Tyson won.
Last night I walked across the stage as a student for the last time, receiving my PhD in aerospace engineering and getting hooded by my advisor in a tradition with roots back to medieval scholars. Even more so than the defense, it marked an official end to my PhD. None of that is really fluid dynamical, but I wanted to use the opportunity to thank each and every one of you who read and support FYFD. This blog began on a whim while I was a graduate student waiting for an opportunity to do the experiments I needed. I never could have predicted at the time the impact it would have on my life. FYFD became a part of my daily life, and thanks to you, readers, it became a source of inspiration and motivation for me as I pursued my studies. I have learned so much more about fluid dynamics in writing FYFD and answering your questions than I would ever have on my own. I have had opportunities to travel, to communicate and even meet with people from all corners of the globe who share some of my enthusiasm for the subject. It has been a wonderful experience so far, and I hope for many more ahead. Thank you all for being a part of it! (Photo credit: J. Mai)
