Recordings
Here are links to some media appearances and filmed lectures:

• During the COVID pandemic I gave a very brief lecture on the science-policy interface in times of global crisis. You can see me lecturing from my study here.
  
• In the spring of 2020 I was interviewed for a podcast by Business News Radio on deploying the wisdom of the crowd in decision making.
• In 2018 I was interviewed for national radio, for an item on statistical inference in science. A stub for the interview can be found here.
• In October 2017 I took part in a debate at the public library in Amsterdam. You can relive the events of the evening here.
• From 2016 onwards the University of Groningen offers an online course for 10-12 year olds, in which I talk about philosophy of science. Have a look at the trailer with subtitles and at the short introduction in Dutch. The whole series can be viewed here, scroll down to see the philosophy items.
  
• In December 2015 I was interviewed for local radio about science and how it shapes our world. Listen to the interview here.
• In November 2015 I gave a short interview about my lectures to legal professionals, as part of a film for the Kenniscentrum Filosofie at the University of Groningen.
• For the 400-year anniversary of the University of Groningen in 2014 I participated in a short film about reorienting ourselves on renewable energy. (The password for the film is "Bart".)
• In July 2011 I gave a presentation on frequentism and chance at the Ludwig-Maximilians university in Munich. My presentation was filmed and can be found among the many other MCMP presentations here.
• In October 2010 the local television network TV-Noord dedicated an edition of their science programme Adamsappel to probability and statistics. Enjoy the interview with footage from the casino and the racing track.
• In February 2010 I won the university-wide Lecturer of the Year Awards. Have a look at my 7-minute lecture on Reasoning with Probabilities. (Downloading Silverlight normally takes only a few seconds.
• In the autumn of 2009 I appeared on local television to talk about the direction of time. Have a look at Adamsappel and fast forward to 6:40 minutes, which is where the part on the philosophy of time starts.
