From Chaos to Life

Entropy

A grand scientific concept that unifies the cosmological, the societal, the microbial, all the way to the atomic: entropy is a key concept in understanding the beginning of the universe, the later emergence of life, and the end of the universe. How should we understand the interpretation and uses of this concept?

Entropy is a very important concept in science, it pops up in a variety of fields. For someone in computer science it’s vital to their ideas of information; for a physicist it is a measure of (dis)order in a system; and for a biologist it is a concept needed for understanding the origins of life. How can an important scientific concept have so many different interpretations, and is this a blessing or should it worry us? The concept of entropy has also been extended beyond the standard scientific fields – like in its use in econophysics or machine learning, and for its ability to measure the redundancy in languages in computational linguistics. Students of science have interpreted the “true” meaning of entropy as whatever helps them solve the problem in front of them, from handling black hole paradoxes to explaining why diamonds form under high pressure.

In this BétaBreak edition we will have experts from different fields discuss their own ideas of entropy, where there is contention and overlap, and how we as scientists move forward with the idea of entropy. We will start by exploring the status quo of the concept, how we got here, where we are heading, and how we can best think of entropy not only within our professional field but as a concept that properly describes physical reality itself.

On Earth, Outer Space, and Space Waste
Clogging up the Final Frontier

Catastrophically thinking, space debris’ specificity—their size, traveling speed, untraceability, and volatility—could potentially wipe out the global satellite system on which many services we have gotten accustomed to rely. Despite the dangers, there is not enough (public) awareness and a lack of concerted efforts to fund and develop clean-up operations. Who is responsible for waste in space? And should we even get rid of all this ‘waste’ or does some of it hold cultural value? What imaginaries do space and space waste encode?

Het wilde deel van de wereld

In het antropoceen stelt de mens zichzelf centraal en probeert hij de wereld op grote schaal te beheersen. De natuur wordt gereduceerd tot instrument en verliest haar intrinsieke waarde. Omgevingsfilosoof Virginie Maris pleit voor een herwaardering van de natuur in haar radicale anders-zijn.

Over de werelden onder onze voeten
Benedenwereld

‘Kijk op een heldere nacht omhoog en je ziet het licht van sterren meer dan duizenden triljoenen kilometers van ons vandaan. Kijk naar beneden en je blik stuit op topgrond, tegel of teen…’. Deze avond presenteert Robert Macfarlane zijn nieuwe boek Underland, vertaald als Benedenwereld, en kijken we verder dan het oog reikt naar de werelden onder onze voeten.
