  • #53: Where Venture Capital Meets Social Purpose - May Samali
    Critical technological and societal changes of the last century have been spearheaded by entrepreneurs and the investors who back them. How do innovators think about using business models to solve today’s most pressing problems? Are financial profit and social impact mutually exclusive goals?
    May Samali (@maysamali) is an investor at the Urban Innovation Fund, a San Francisco-based venture capital firm that invests in startups shaping the future of cities.
    Prior to her career in venture capital, May worked as a corporate lawyer and as a judicial clerk to the President of the New South Wales Court of Appeal in Sydney. She studied Law, and Economic and Social Sciences, at the University of Sydney, graduating with the University Medal, and she holds a Master in Public Policy from the Harvard Kennedy School of Government.
    Joe caught up with May in San Francisco to discuss what motivates her; why she made the switch from law to venture capital; her criteria for deciding whether to invest in a company; and how a career in venture capital can be an unexpected way to achieve social impact.

  • #48: My Friend Richard, and Theories of the Universe - Leonard Susskind

    Leonard Susskind is the Felix Bloch professor of Theoretical physics at Stanford University.  He is widely regarded as the father of String Theory.

    In this episode, Joe joins Leonard at Stanford to remember Leonard’s friend and mentor Richard Feynman, one of the great physicists of the twentieth century. They also discuss Leonard’s famous ‘Black Hole War’ with Stephen Hawking, String Theory, the multiverse, and what it’s like to be a 78-year-old physicist.

  • #47: The Shape of Probability - Harry Crane

    Harry Crane is a scholar who specialises in statistics and probability. He is currently a professor of statistics at Rutgers University.

    In this episode, Joe catches up with Harry in New Jersey to discuss the history of probability, how experts routinely misuse statistics, “The First Rule of Probability”, the replication crisis in science, and how Harry thinks about probability in shapes rather than numbers.
