 16:45-Romain Franceschini: Crafting simulations in Crystal,romain.jpeg (https://dl.airtable.com/.attachments/933f40fb6bf183a8b68e6b964caf4fe6/dc3a7d38/romain.jpeg),Scientific,16:45,17:00,Short Talk,15,,Track 2,Crafting simulations in Crystal,Romain Franceschini,"In this talk, we will explore how you can use the Quartz shard for constructing simulations using a discrete-event abstraction in a bottom-up fashion. The modularity of the formalism it relies on helps you define models able to capture complex dynamic systems.",RomainFranceschini,https://www.youtube.com/watch?v=mwfmsT-6Mx8&list=PLe1-A91ZPTpAhkbyQSFbF5DdZEFhlMxEL&index=6,

 17:00-KC Erb: Why I Choose Crystal for Science,kc.jpeg (https://dl.airtable.com/.attachments/7d487ba5e4109282eb18bc94ab68a9da/adf79bc1/kc.jpeg),Scientific,17:00,17:30,Long Talk,30,,Track 2,Why I Choose Crystal for Science,KC Erb,I would really like to promote the idea that object-oriented design principles are under-utilized in the sciences. I believe that Crystal really strikes that perfect balance that the sciences need today between dynamic and performant. It's a shame that too few scientists are taught to reason about code abstractly in the same way as mathematical formulas but I think Crystal can change that.,KCErb,https://www.youtube.com/watch?v=0gY1LAiRdwg&list=PLe1-A91ZPTpAhkbyQSFbF5DdZEFhlMxEL&index=7,
