Standard and alternative cosmological models
Pulnova, Yelyzaveta ; Acquaviva, Giovanni (advisor) ; Žofka, Martin (referee)
The main aim of this thesis is the study of the dependence of the scale factor on the cosmic time for different models of Universe's evolution in the framework of the general theory of relativity. In this thesis we consider the FLRW metric and admit nonzero curvature. The models we consider differ from each other by the equation of state of the source, hence by the composition of the cosmic fluid under study. In this thesis the following models are discussed: ΛCDM (we consider a perfect cosmic fluid consisting of the incoherent dust, radiation and a cosmological constant in a curved space-time), generalized Chaplygin gas, and, also, two kinds of the scalar field (describing separately power-law inflation and the period after recombination). The numerical and analytical results obtained are processed graphically. 1

Concept of the Soul in Jainism
Linhart, Matěj ; Vojtíšek, Zdeněk (advisor) ; Bartošek, Josef (referee)
This thesis aims to summarize and explicate a conception of the soul in Jaina tradion with a presentation of appropriate context. The thesis is divided into three parts. The first part of the thesis is dedicated to Jaina metaphysics and cosmology. The second part is deditacated to the conception of the soul (jiva), karma and spiritual progress of a man. The last part is dedicated to the religious pracitces of Jains associated with this doctrine - especifically to the phenomenon of non-violence and voluntarily starvation to the dead (sallékhana).

Ethics in the Chinese Debate of Science and Life Philosophies: Wu Zhihui
Typl, Lukáš ; Hudeček, Jiří (advisor) ; Lomová, Olga (referee)
The aim of this thesis is to eleborate a detailed analysis of Wu Zhihui`s essay: New faith and its view of the universe and of man and attempts to fill the still large gap in secondary literature. The method focuses on basic interpretations of Wu Zhihui's ideas and putting them into the context of Western philosophy. It emphasizes direct quotations and translations of key texts to Czech language. Through the analysis of his view of faith, knowledge, metaphysics, cosmology, ontology and human life attempts to uncover the grounds of Wu Zhihui`s ethics and basic philosophical theses of this significant thinker of atheism, humanism and modern ethics. Key words Ethics, cosmology, metaphysics, philosophy of man, China, Wu Zhihui, atheism, materialism, faith

Empedocles' cosmology
Šteffl, Jan ; Milko, Pavel (advisor) ; Hogenová, Anna (referee)
The aim of this bachelor thesis is to demonstrate how were the presocratic philosophers thinking about the creation of the world. The first part is focused on a brief description of the life of Empedocles, as well as it defines main conceptions of the idea of cosmology. The main part of the thesis is trying to analyse four elements, which we can hold as substances. Besides for their paramount role in Empedocles' cosmology, they are also mentioned since Empedocles is often understood as their founder. The following chapter explains the problem of Love and Strife which both cooperate with the four elements and they all participate on creation and destruction. This chapter is introducing us to the problems of cosmic cycles and Sfairos, which are often considered to be the major phenomenon of Empedocles' cosmology and philosophy. These ideas are also described here because of the possible comparison of various religious trends and religious thinking.

Určování parametrů temné energie a modifikované gravitace v rámci projektu LSST
Vraštil, Michal ; Prouza, Michal (advisor) ; Heyrovský, David (referee)
Temnáenergietvořícípřibližně70%hmotyvesmíruz·stávájednouznejvětšch záhad moderní fyziky. K pochopení její podstaty jsou potřeba přesná kosmolog- ická měření. Jedním z projekt· zkoumající tuto exotickou formu hmoty bude i Large Synoptic Survey Telescope, který pom·že potvrdit či vyvrátit standardní kosmologický model (ΛCDM). Pro úspěch projektu je potřeba prozkoumat r·zné teorie temné energie. Jednou z alternativních teoríí vysvětlujících urychlenou expanzi vesmíru je tzv. chameleoní gravitace. Chameleon je nové skalární pole s hmotou závisející na okolní hustotě. V hustých prostředích jako je například Sluneční soustava získává pole velkou hmotu a propaguje se pouze na malých vzdálenostech díky čemuž m·že uniknout standardním test·m gravitace. V prá- ci mimo jiné studujeme chování chameleoního pole v okolí hvězd a v galaxiích. Ukazujeme také za jakých okolností je toto pole možné detekovat pomocí spek- troskopických měření a slabého čočkování.

Navajo Ritual Healing
Galovič, Roman ; Chlup, Radek (advisor) ; Kozák, Jan (referee)
In this paper I deal with two traditions of ritual healing in Navajoland, namely with the traditional Navajo ritual healing and the peyote healing of Native American Church. I introduce them in three dimensions when I consecutively describe a cosmological framework, a social organization and a specific example of a ritual. At the core of my analysis is the grid & group method that was developed by Mary Douglas, when I look for the correlations between cosmological notions and social structures, and the ways they are established by the ritual. This way I point out how the colonial oppression weakened community ties and created ground for the growth of Native American Church in Navajoland, because NAC is able to offer existential answers for life in such a desolate space. However this does not mean that the Traditional Navajo healing was wiped out by colonialism, and both traditions continue to exist side by side and are quite often combined by particular patients. I offer a way to interpret this medical plurality when I fuse Mary Douglas' method with certain traditional Navajo notions and psychological analyses by Friedrich Nietzsche. In this view, every person would be permanently situated in socially and phenomenologically heterogenic space, and particular healing traditions would heal different social...

Early Buddhist Cosmology of the Pali canon
Horáček, Petr ; Holba, Jiří (advisor) ; Melnikova, Nora (referee)
This paper is focused on the early Buddhist cosmology. It briefly presents the general concepts of cosmology in Buddhism and the Pali Canon in order to better emphasize the characteristics of the primary text on which the work is based, namely the Agaññasutta of the Pali canon. The author takes into account other suttas of the Pali canon and secondary literature as well. The Agaññasutta represents one of the first cosmological texts of Buddhism and can therefore be considered as a very valuable source of information about the early cosmological ideas and the context in which these ideas were formed. It deals with the destruction of the world, its re-emergence, the emergence of creatures, human beings and social strata, the election of the first king and the establishment of the ascetic social groups. To gain a better orientation in the source material, the plot can be divided into the period until the development of human beings, the creation of social institutions with the election of the king and the emergence of alternative social institutions headed by a Buddhist monk. The main aim of the present paper is to show that the Agaññasutta contains the structure based on the necessity of the emergence of the human beings in their physical form and endowed with their moral faults, the society which...

Religion and Society in the Quran and Their Relationship to Pre-Islamic Arabia
Oudová Holcátová, Barbara ; Chlup, Radek (advisor) ; Ťupek, Pavel (referee)
My goal in this thesis is to concentrate on the origins of Islam as we can understand it from the Quran itself, without using other, later sources. At the same time, I am interested in the relationship between pre-Islamic Arabia and early Islam. My method will be based primarily on Mary Douglas and her grid- group analysis. This British anthropologist attempted to analyse different social situations, in which various systems of understanding the world are formulated, using the parameters of "group" (the degree to which the borders of a group are defined) and "grid" (the number of rules by which an individual is controlled). These two parameters then made it possible for her to classify different cosmologies according to their ideas and their social reality. Applying this method, I will attempt to extract from the Quran - not primarily a narrative text - a description of the change of early Muslims' social situation and development of their religious ideas which is connected to it, and I will attempt to use Mary Douglas' anthropology to explain how such a transformation happened and could happen.
