In this episode, we must discuss drugs. Many people experiment with recreational drugs like Cannabis and MDMA every now and then. But do we know how they affect our brain? Although some research has been done on their negative effects, it is only recently that scientists started to do research on the medicinal effects of Cannabis, MDMA, ketamine and psychedelics. We talk about this and much more with our two guests: Olivier Otten and Sebastiaan van Bruchem. Olivier is an art student and tells us about his experience with Cannabis and how he felt it helped him with his attention disorder. Sebastiaan, who finished a Masters in Brain and Cognitive Science, explains what science can tell us about the effect of drugs on the brains.

Must Discuss: Drugs

In this episode, we talk about crystals with Noushine Shadidzadeh, professor of crystallization at the UvA. We can all agree: crystals are beautiful to look at. And this is exactly what Noushine loves about her research field. Interestingly enough, crystals play a huge role in our everyday lives, for example in food - think of salt - and in drugs such as paracetamol. During this episode, we will come across various applications of Noushine’s research: from reducing the amount of salt in food to fortifying salt with rare minerals and even preserving cultural heritage. Well, you get it: crystals are everywhere around you! Listen to this episode and let the science behind crystals be unraveled for you.

The World Of Crystals Around You!

Cooperation is everywhere around us, at the heart of nature's most triumphant endeavors. It shows up in the cells that make up complex organisms, in ant colonies, and, of course, in the societies we live in. But it is also a bit of a mystery, because it involves being helpful at a personal cost. So how can individuals be motivated to look beyond their immediate self-interest and embrace the enduring advantages of collaboration? It turns out that game theory, a tool loved by economists, has much to say on this. Joining us for a discussion on the mechanisms underpinning cooperation is Fernando P. Santos, Assistant Professor at the University of Amsterdam. He guides us through the core concepts of game theory, shows why reputation is important, and gives insights into what to anticipate when engaging with artificial agents.

Logic has a rich philosophical history for understanding the limits of our reasoning. But can it also be used for computational tasks? Nick Bezhanishvili is the President of the Dutch Association for Logic and Philosophy. His main field of research is the relationship between algebra and geometry. He recently researched the application of polyhedral semantics for 3D modeling.

On The Otherside (Balearic Mastermix)

You have probably heard of black holes. They are known as all-destructive holes that sluck up everything that comes near it. Some say they might be used as time machines! But what about this is science, and what is fiction? In this episode, Sera Markoff shares insights about how she made the first picture of a black hole, time in black holes and the importance of science for society.

Black Holes: A Nice Place To Retire?

We are in touch with democracy every day. For example, when the population of a country needs to make a decision as for who should rule their country. However, democratic decision making takes place on much smaller scales as well. Think of a committee that together has to decide who to hire for a job, or if you have to choose a restaurant with a group of people. But did you know that there are in fact many different ways in which you could run a democracy? And that computer science can actually help to design ways to run a democracy? In this episode, Ulle Endriss, professor of Computational Social Choice, talks about politics, participatory budgeting and of course their relation to: computers! Because computers can help us when it comes down to making collective decisions, whether big or small. Listen to find out why!

One of the things we discuss in this episode, is that every voting rule in which it is impossible to vote strategically, will result in a dictatorship. Watch this video to find out more: https://www.youtube.com/watch?v=sJcqNEyTUwg

What Does The Democracy Of The Future Look Like?

Het is zaterdagavond, 20 februari 2010, als een groep mannen met bivakmutsen een vakantiehuisje binnendringt, de bewoners mishandelt en op de vlucht slaat. De dagen erna volgt intensief onderzoek en verderop worden bivakmutsen, met DNA sporen, in de berm gevonden. Helaas is dit nog geen concreet bewijs dat de bivakmutsen daadwerkelijk van de daders zijn. Er zijn tegenwoordig echter manieren om toch de kracht van een bewijsstuk te meten met behulp van kansberekening. Hoe veel waarschijnlijker is het dat de bivakmutsen bij het misdrijf horen dan dat de bivakmutsen daar toevallig liggen? Hierover praten we in deze aflevering met Marjan Sjerps, hoogleraar forensische statistiek aan de Universiteit van Amsterdam!

Wiskunde Tegen Misdaad: Een Buitenkansje?

It is almost impossible to imagine the world without plastic. Plastic is everywhere around us! However, nowadays there is so much plastic pollution in the world that it has become one of the biggest problem for nature and humanity. This has led to the development of alternatives in recent years. One of which you may have heard is bioplastic. But how much of the current bioplastics are actually "bio"? How much better are they for the environment? We talk with Maria Murcia Valderrama, PhD student in polymer chemistry and specialized in bio(degradable) plastics, to seek answers to these important questions.

How "Bio" Is Bioplastic?

We present to you: our new format Must Discuss! In Must Discuss, we open up a discussion about the most pressing questions in science! We invite a group of students and researchers from different disciplines to shed their light on a subject from their point of view. 

We must discuss: Time. Chances are that you think that time in the universe passes at the same rate for everyone and that there is an absolute past, present and future. However, according to modern physics, this common picture of time is not correct. Special relativity theory, for example, tells us that moving clocks tick slower! We will talk about the consequences of relativity theory for our conception of time and about more puzzling questions related to time, such as: Can we change the direction of time? Is time travel really possible? We will discuss these questions with Grace Shao, a Philosophy Master student, Hidde Fokkema, who completed a Bachelors in Physics, and Sean Gryb, PhD-student in Philosophy of Physics.

Must Discuss: Relativity Of Time

In this episode we talk about evolutionary robotics. Evolutionary robotics is a new approach to artificial intelligence. Standard artificial intelligence designs solutions for small problems, such as playing chess games. The problem with robots designed in this way is that they will not be able to live a human-like life, solving many problems simultaneously. This is where evolutionary robotics comes in: it lets evolution design robots that are perfectly adapted to a certain environment. For this reason, evolutionary robotics can produce robots for applications where standard robotics is not able to find solutions. Think of robots for seabed mining, robots keeping an eye out in rainforests and robots cleaning old nuclear power plants. Follow us on our journey this episode to discover how evolution can be implemented in robots. Explore the implications of evolutionary robots, because if evolution created life, do we create artificial life with artificial evolution? On the way, enjoy songs such as Seu Jorge’s “Life on Mars” (yes, a cover of David Bowie!) while we explore the options of a robot evolution on Mars.
