Abstract
English abstract
This project report explores the different phases that a specific physical model undergoes in its journey from conception to rejection. The purpose of the project is to understand how an idea is conceived, which challenges this idea may face, in the form of knowledge or a lack there of, religion, politics and academic competition, and how the scientist may bear witness to the falling apart of his fundamental belief in the light of new discoveries. The project describes the historical background of the Steady State model, and concurrently considers some of the strengths and weaknesses which defined the model at the time when it was still recognised as a potentially valid model of the universe. Subsequently, the project discusses how an idea for a new model may be attained, as well as the ideas that reinforce the model, and the one idea that ultimately proved the model invalid. Furthermore, the competition that was waged between the Steady State model and the Big Bang model is discussed, in order to achieve an understanding of the ways in which this competition influenced the development of the Steady State model. The project concludes that no definite answer exists as to how the idea for the creation of a new model is attained, as there may be a vast array of reasons for the emergence of an idea. Finally, it is concluded that the competition between the models has only meant that none of the models garnered a significant majority of supporters until scientific experimental substantiation of the Big Bang model was established.

Abstract
English abstract
This project is a pilot project that examines the difficulties that arise when a group of students solves problems by dimensional analysis. The project puts up two hypothesis', which respectively states that it will be difficult to choose the correct variables, and analyzing the exercises will be tough without the necessary level of known theory in a given subject. The basis of the study is made from a video recording of four Bachelor students from Roskilde University. The participants are asked to solve four different exercises, each of which is selected in the matter of their difficulty level and topic. These video recording gets transcribed from which an analysis is made of the following: Their structure and order, their analysis of the exercises, their choice of variables and the mathematical treatment. This is used in a discussion of the difficulties they have with the exercises while doing dimensional analysis, as well as a discussion of the method in which these empirical data is collected. The project concludes that participants in this study overall experience difficulty with analyzing the exercises they have been asked to solve, and as a consequence of this, they experience it to be difficult selecting the correct variable, to do dimensional analysis. Also the conclusion indicates that the students have a harder time solving exercises which deviates from exercise they have experienced in the past.

Abstract
English abstract
This project is written as a project of reflection over physics. It seeks to clarify how simplifications and assumptions in physical models is applied and justified. This problem statement is considered based on four models of the kinetics of gases; Boyle's static and dynamic model of air respectively; Bernoulli's model of ideal gases; Maxwell's model of the viscosity of gases; and the equation of state by van der Waals. This project gives an account for each of the models, which leads to a discussion of the background for the model including established experimental results at the time of the modeling, the perception of molecules expressed in the model and how the ideal gas equation is applied in the model. This project concludes that simplifications and assumptions in models are generally justified by a reference to empirical data consistent to the model and by physical and mathematical reasoning. Furthermore, simplifications and assumptions is generally applied in the model to create a simple representation of the observed phenomena.

Abstract
English abstract
On the doorstep to the 20. century the basis of one of the prime areas of physics throughout the century was established, the conception of structure of matter. To this time there was great differences in the views of, on one hand, the atomistic nature of matter and on the other hand, if accepting the atomistic structure, if these elementary particles were indeed the atoms, or if the atom could be divided. In 1897 J.J. Thomsen succeeded in detecting the existence of the elctron and thereby establishing the atomistic structure of matter. J.J. Thomsen even succeeded in showing that these subatomic particles were identical for different matter, which led him to suggest that the elctron was indeede a shared fundamental part, an elementary particle. In the 15-20 years to come science searched for the actual charge of this elementary particle, the "atom of electricity". A great deal of methods and scientist competed in who were able to establish the most acuurate value for the charge. One of these competitors was Robert A. Millikan who happened to be victorious. The method of Millikan will be described in this report and so will the evolutionary scientific process which brought him to the victory through equal amounts of smartness, diligence and chance. The resulting method, the experimental set-up as well as the physic/algebraic manipulations tends to resemble a "miracle". In recent years accusations has been made towards Millikan, that he, in his strive for perfection, has violated the ethic rules of science - acted with misconduct. This report seeks to analyse the grounding and legitimacy of these accusations by comparing the claimed actions of misconduct to the norms of the scientific community. The report concludes that based on the available sources, it is not "beyond any doubt", that Millikan is guilty as charged. On the other hand, it seems that Millikan has indeed acted with misconduct, but not in the way that he is actually accused. Besides taking the credit for his own doings Millikan seems to have made a deal involving him being credited for the work of others. Taking credit for the work of others is just as well an act of scientific misconduct - and one that in no way is regarded as less offensive.

Abstract

This project deals with the relationship between the mechanical and dielectric properties for supercooled viscoelastic liquids at temperatures above the glass transition temperature TG of liquids. Mechanic and dielectric measurements have been made for the liquids; 1,2 propanediol and methyl m-toluate. It is shown how the measurements differ frrom the basic models; Maxwell and Debye. The relaxation timesT of the liquids are found and it is shown, that the Vogel-Tammann-Fulcher equation is a good description of the relationship between temperature and relaxation time, for both mechanical and dielectric measurements. By using this equation, the glass temperature of the liquids is determined. Moreover the project shows, that the relaxation time of the mechanical measurements are shorter than the dielectric at a given temperature. We have examined whether the liquids obey time-temperature superposition (TTS), for the dielectric as well as the mechanical measurements. In view of this it is shown, that the top of the alpha-relaxation for the mechanical measurements are wider than for the dielectric. The maximum dielectric loss (formel) for 1,2- propanediol is found to be relatively high about 15-19, whereas for methyl m-toluate it is determined to be approximately low, about 1-2. The minimum slope is determined and its association with the maximum dielectric loss of the liquids have been found. Furthermore we estimatem the maximum loss of shear modulus (formel) as a function of minimum slope. It is shown, that there is tendency for liquids with high maximum dielectric loss, to have a numerical minimum slope around 0.5. It has been found, that the same relation between the maximum loss of shear modulus and minimum slope applies. Finally it is shown, that liquids, which obey TTS, has a numerical minimum slope around 0.5 (formel) 0.1.

Abstract
English abstract
This report deals with what in physics didactics often is called typical problems (in this report called text book problems). I.e. that kind of problems that is normaly done during education in physics. The common idea of this kind of problems is, that they primarily is training use of formulas and mathematics. Our gouls is to answer what purpose this kind of problems have. To describe how it can be used to learn physics, we have used the commonly accepted competence description of mathematics, to make a corresponding description of physics. With this description we analyze a number of text book problems, and the answers to them made by som students, to decide what competencies that is trained by doing the problems. Further we construct some problems of another type, to test what competencies that has not been trained.

Abstract
English abstract
The main purpose of this paper is to achieve insight in the reactions towards the anomalies to understand the influence that reactions have upon the development of particle physics with the neutrino history as a turning point. In answering this, a presentation of the philosophers of science Kuhn, Popper and Lakatos is included and the historic span of the discovery of the neutrino in the period of 1900-1980 is described. The theories from the philosophers of science, forms a foundation for our defintion of an anomaly, and they are used in understanding the reactions. We conclude that the reactions to, and the dissolution of anomalies has changed the praxis of normal science in particle physics in the period beheld. This is seen in the chance that the physicists make when they turn from primarily concentrating on describing known particles, to both describing meanwhile focusing on finding new particles.

This project treats the subject of which skills we find to be realistic and desired for students taking physics on a compulsory high schools level to obtain during a period of studies when working with vibrations in wineglasses. The relevance of these competencies is alsom treated. On this basis a study period was developed and tested on second year students whose ability to gain the desired competencies was evaluated. During the development of the study period we found it desirable and realistic that the students should be able to develop competencies in their frame of thinking, using experiments, reasoning, and modelling from this study period. A number of goals for the students were set in order to evaluate the students gain from the study period. For each of these goals a desirable level of understanding was defined using Blooms taxonomy. By testing the study period we experienced that the student did not quite reach the desired levels of understanding set by our goals. Thus we must conclude that the students did not develop the desired competencies from our study perod. One of the reasons for this could be lack of basic understanding from the students and their problems using mathematics ind a physics context. Also the student experienced problems expressing themselves using the correct terms and symbols. On the basis of this we have learned that in this kind of study period mathematical and communication competencies should also be in focus.

Abstract
English abstract
This report contains a discussion on determinisme and chance based on an essay by J. Monod "Neccessity and Chance" and two articles by C. S. Peirce "The Doctrin of Neccessity Examined" and "Evolutionary Love". Assuming that Peirces theories are consistent with the Fluktuation-Dissipation theorem it is discussed in contrast to J. Monods naturalphilosophy whether chance or determinisme is rulling. Peirces Phaneroscopy is presented and utilized on the material in question in order to reveal the coherence present. It is concluded that scientific laws are statistical expressions and not absolute truths.
