This thesis consists of three chapters, the first two of which concern division points of elements of the multiplicative group of a number field.

In my research, we developed a method to distinguish knots. A knot is a mathematical depiction of the everyday knot that occurs in ropes and cords.

Dividing Worlds: Tsunamis, Seawalls, and Ontological Politics in Northeast Japan

We consider the propagation of electrical signals through nerve fibres.

Measurements on a superconducting material show an abrupt transition between a normal metal and a 'strange' metal. The really strange thing, however, is that this abruptness disappears when the temperature falls. 'We don't have any theoretical machinery for this', says theoretical physicist Jan Zaanen,…

This thesis consists of three chapters. Each chapter is on a different subject. However, all three chapters address issues that arise in counting arithmetically interesting objects.

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

The Physics and Cosmology specialisation consists of 120 European Credit Transfer System (EC) points and consists of mandatory courses (33 EC), electives (27 EC) and two research projects (60 EC in total).

What are the 'dark' components of the universe?

You have ample opportunities to assemble your own study path. The courses cover the full spectrum from theoretical early universe to observational cosmology.

My work is motivated by the necessity to extend Standard Model of Particle Physics in order to explain three observed phenomena that this great theory fails to accommodate

The Astronomy and Cosmology specialisation consists of 120 European Credit Transfer System (EC) points and offers advanced Astronomy and Physics courses and two research projects.

DNA carries various forms of information. Out of these forms of information the most well-known is classical genetic information.

In September 2021, ACPA PhD Candidate Gabriel Paiuk will premiere a new work titled Sound Theory (The Clouds) as part of the 2021 Gaudeamus Muziekweek Festival. The performance will take place on September 10th, 20:30 at the De Helling (Utrecht, NL).

In this thesis, the research focuses on the properties of dark matter and dark matter haloes and how they connect with the galaxies we can observe in the Universe.

Conspiracy theories are of all times, and the government should never dismiss them as a fantasy of fools. Certainly not now, when it turned out that authorities made a conspiracy themselves with a journalist threatened with murder. Which proves that the truth is always more insane than you could have…
