    Randomness
    Jan 8 2025
    Is all life predestined, or is existence blown about by the whims of entropy? If we restarted the universe with the same world generating seed a la Minecraft, would it all play out the same??? These are ginormous questions that we do not get into in this episode! Instead, we're examining slightly more manageable examples of randomness in nature, in computing, and even in ourselves.

    Special Episode: "Our Big Shot" from Chalk and Blade Productions
    Jan 3 2025

    Hello Tangents listeners! We are off this week to rest up and enjoy the holidays, so in place of a regular episode we have a super special treat from friends of the show that we're excited to share! We're dropping an episode of a new podcast series from Chalk and Blade Productions called "Our Big Shot."

    What if we could build a disease free world? Well, we almost have. We are at a point in history where we have a Big Shot to make that happen. Dr Seema Yasmin, expert in disease control, brings you the stories of disease eradication, and the pioneers who can tell us how to finish the journey. These conversations will make you smarter, entertain and surprise you, and give you hope for the future of humanity.
