    What’s Math Got to Do With It? Math & The Social Good

    What’s Math Got to Do With It? Math & The Social Good

    It is 8am,on a wintry Monday. You have your coffee cup in hand as you rush towards the bus stop. It is the middle of winter, so the buses are taking longer than usual. Checking your phone, you learn that the blizzard has caused an accident on the main highway. Alternate routes on your map app appear (like magic) just as you brace for a hectic start to your week.

    How did the app configure your route so fast? Within seconds, your headache of a route has turned into a minor hurdle. How, you ask? Math. Mathematics, the silent hero of the modern world. On Perpetual Notion Machine, host Anita Nsubuga explores math and its modern-world applications with guest Laura Albert, from UW Madison’s School of Industrial & Systems Engineering.

    We learn how math optimizes our world. Math is more than theorems; it is practical and effective in many aspects of our modern way of life. What’s Math Got to Do With It – a lot, as we will soon find out.



    Stay tuned!

    An Audio Tour of the Longenecker Horticultural Gardens

    An Audio Tour of the Longenecker Horticultural Gardens

    There’s no time like a beautiful August day to head to the UW Arboretum. Join us for a guided walking tour of the Longenecker Horticultural Gardens. Curator David Stevens leads Perpetual Notion Machines’ Patrick Sajbel on this special field visit.

    Listen about the history of the Arboretum and the special flora and fauna (!) that live in the Longenecker Botanical Gardens, including selected rare species like the American Chestnut, a maple tree shaped like a pencil and the mobile sculptures that move in the wind like maple seed pods (or samaras) of the state trees of Wisconsin.

    The Gardens are a major free resource for the study of landscape plants for educators and open to the public.

    Originally broadcast in two pieces on August 11 and September 15, 2022. Photo courtesy Patrick Sajbel.

    Will the Reign of Monarchs Continue?

    Will the Reign of Monarchs Continue?

    The lifecycle of monarch butterflies is one of the most remarkable of any migrating species. As familiar as these beautiful insects are, last month monarchs were listed as endangered species. In this edition of the Perpetual Notion Machine, host Patrick Sajbel welcomes Dr. Karen Oberhauser to explain what is happening in the monarch population and what can be done.

    Oberhauser is Director of the University of Wisconsin Arboretum and the founder of the Monarch Larva Monitoring Project. Karen is a Wisconsin native, researcher and educator. She earned degrees at Harvard, Wisconsin and Minnesota.

    Resources noted for monitoring monarchs and citizen science programs are linked here: Monarch Joint Venture, and Journey North

    Linked here are resources for growing milkweed and supporting monarchs in Wisconsin. Gly

    Fisheries: Where the Walleye Are

    Fisheries: Where the Walleye Are

    Cheese curds (those chewy nuggets of milk found in the farm’s market ). Frigid winters (puffy, cozy coats worn on the lakes, fishing).Fish fry Fridays (buttery flakes of walleye served at the end of the week). The quintessential Wisconsin experience.

    All year long, we fish, hoping to grab one of those flaky walleye.

    On Perpetual Notion Machine, host Anita Nsubuga with guest Zachary Feiner, a fishery expert and research scientist at the University of Wisconsin–Madison’s Center for Limnology, explore fisheries & the walleye.

    What is a fishery?

    Where the walleye are?

    How fisheries have changed over time, due to climate change?

    What other fish could be thriving due to climate change?

    Should we even eat walleye?

    To find out where the walleye are… stay tuned!
