Museum visit to the Ole Rømer Museum

We will have a small lecture on Ole Rømer as well as a general tour of the museum's permanent exhibition on astronomy and Ole Rømer, a special exhibition on goals and weights through 350 years "measured and weighed" and a brand new exhibition on the occasion of the 25-year anniversary of the Ole Rømer Museum. Registration for this event is necessary and can be made to Bente Egaa, tel.: 35 87 88 04 or email: bente.egaa@uni-c.dk by 25 October. There are no public transport options to the museum, located on body Pedals Allé 3 in Tåstrup. We would like to try coordinating the co-driving, so if you have the opportunity to...

Tycho Brahe

The lecture presents the view that the entire empirical natural science originates from the work of the Danish astronomic. Through Tycho's observations and Kepler's bills, the quantitative science – for the first time in history – reached a peak. Tycho Brahe is thus one of the few Danes who has had a decisive influence on the history of the world.

Steno and Reality

Descartes: ".. To seek the truth of [nature] the sciences "(Discours de la méthode.., Leyden 1637) described the new philosophical and scientific spirit in the Europe of 1600. Niels Stensen, born in Copenhagen in 1638, studied medicine at the university on the basis of classical language and culture and met the modern currents through the literature until he in 1659 received support for a study trip in the leading western Europe. An excellent school from Copenhagen, developed abilities for observation and analysis and inspiration from like-minded led him to new realization in the field of anatomy, physiology and since the geoscience that aroused admiration in the formed Europe. Stenos language proficiency, sensitivity and...

Anniversary Event

The SNU has the year 180 anniversary. This we have chosen to celebrate together with the Youth Science Association (UNF), which this year has 60 year anniversary. On this occasion, we would very much like to invite Stumi'S faithful members to the anniversary party on H.C. Ørsted's birthday. The event starts at noon. 15.00 With anniversary speeches and awards on the big Scene followed by a reception at noon. Approx. 16.30 to 17.30 in the Banquet Room 2. Both the SNU and the UNF look forward to a festive day of great attendance. Registration is made to: Bente Egaa on Tel: 35 87 88 04 or email: bente.egaa@uni-c.dk by 1. August 2004. Before...

Mathematical algorithm and analytical epidemiology in the investigation of outbreaks of disease

It was once believed that infectious diseases were under control in the industrialised part of the world. We are now smarter. Globalisation, as well as changing living conditions and international food production, helped to show new infectious diseases, while old-fashioned diseases once again become relevant. To counter this threat, the monitoring of diseases is necessary. The purpose of this disease monitoring is, inter alia: To detect outbreaks so early that the source of infection can be found and the route of infection is broken. In the lecture I will show examples of the use of mathematical algorithms for "automatic" to find outbreaks, like the use of statistical methods as a tool to...

Modeling of non-stationary financial time series

The statistical analysis of economic time series has formed the basis for economic decisions for many hundreds of years. The methods have long been based on the assumption that the series were stationary, and it is not until the last 20 years that methods based on non-stationarity have been developed. The essential concept is "cointegration", introduced by Clive Granger, for which he received the Nobel Prize in Economics in 2003. The term provides the ability to model economic relationships as stationary relationships between non-stationary processes. The concept will be examined in connection with the widely used error correction model, and as economic example and motivation I will use the "law...

Statistics in environmental contexts

Environmental problems have been given a great deal of attention in the public over the last few decades. In parallel, the requirement to be able to demonstrate the state of nature and the environment is increased in the desire to optimise efforts to reduce the human impact of nature. Examples of the use of the statistics to document the nature and environmental status of the marine areas will be examined. In addition, the focus will be on the use of indicators of natural and environmental status and the statistical problems such a simplified description of the ecosystem entails. Finally, the necessary dialogue/interaction between statisticians and biologists/chemists will be highlighted.

Statistical pages of Physics

The idea of probabilities has been in human beings at least as long as science. If you do not have complete knowledge – and you almost never have – then you have to resort to probabilities. Despite its age, there is surprisingly great disagreement over the status of the concept. How do you determine a probability, for example? Is it absolute and objective? In physics, the problem has existed for many hundreds of years, and has literally demanded death victims – for example, Boltzman, who took his own life, was very depressed by the criticism of his probability interpretation of concepts such as temperature and entropy. Out of just the studio...

Risk and likelihood of setting fishing quotas

Fishing quotas are set politically, each year the Fisheries Ministers meet in December to set next year's fishing quotas, a ministerial meeting that attracts a lot of media attention. The Ministers shall take their decisions, inter alia: Based on an assessment of the number of fish in the sea and the risks associated with different future fishing quotas. This assessment takes place during the year and is coordinated through the International Council for the Sea (ICES). The studies and analyses are carried out by researchers employed by the national fisheries research institutes. In Denmark it is "Denmark's fisheries surveys" that are responsible for the Danish contribution to this international work. Assessment of how many fish there are in...

Codes, games and entropy

In situations where conflicting interests are broken, the parties can often agree on a "balance" or also arise such – for example, in the economy – so to speak by themselves. Conflict situations such as these can be treated as games. A little surprising, this also applies to situations where a nature observer tries to unfriend the nature of its secrets. It can be regarded as a game between the observer and nature. But what are the rules and what do they play about? Here, codes come into the picture as models for observation strategies. The observer wants to observe effectively, but it seems as if nature is a counterplayer who tries to complicate...
