  1. 11. Relativistic Visualizations

    Magister-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Andreas Ringstam; [2020]
    Nyckelord :Special relativity; Visualization; see; observe;

    Sammanfattning : Special relativity is an area of physics that is abstract and consists of concepts and effects that is hard to link to everyday experience. From a learning perspective, that is problematic as we form new knowledge by linking it to old experiences. One approach to experience a relativistic environment is through computer simulations.

  3. 12. B-plane orbital resonance analysis and applications

    Master-uppsats, KTH/Rymdteknik

    Författare :Alessandro Masat; [2020]
    Nyckelord :;

    Sammanfattning : Many space engineering and orbital mechanics applications seek for the usage of focused mathematical models, capable of providing useful insight onto particular phenomena or exploiting some theoretical and physical tools to reduce the computational costs and/or increase the level of accuracy reached. Orbital resonances are one of the phenomena that needs to be properly modelled, both for exploiting such features in the mission design phase and to predict possible resonant returns of threatening objects closely approaching a specified planet.

  4. 13. Spacetime as a Hamiltonian Orbit and Geroch's Theorem on the Existence of Fermions

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Viktor Bergstedt; [2020]
    Nyckelord :3 1; ADM; black hole; canonical quantization; Cauchy surface; causality; differential geometry; Einstein-Hilbert action; general relativity; Geroch; globally hyperbolic; Hamilton s equations; numerical relativity; parallelizable; SL 2; C ; spacetime; spinor; spin structure; SO 1; 3 ; Stiefel-Whitney class; tetrad; topology;

    Sammanfattning : Over a century since its inception, general relativity continues to lie at the heart of some of the most researched topics in theoretical physics. It seems likely that the coveted solutions to problems like quantum gravity are to be found in an extension of general relativity, one which may only be visible in an alternate formulation of the theory.

  5. 14. Numeriska algoritmer för tidsfördröjd Newtonsk gravitation

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Erik Weilow; Anton Hilding; [2019]
    Nyckelord :;

    Sammanfattning : Upptäckten att Merkurius omloppsbana precesserade anomalt gäckade dåtidens forskare. Ett flertal teorier - allt från nya planeter till interstellärt damm - postulerades i syfte att förklara fenomenet. LÄS MER

  7. 15. Simple cosmological models and their descriptions of the universe

    Kandidat-uppsats, Linköpings universitet/Matematik och tillämpad matematik

    Författare :Emil Gustafsson; [2018]
    Nyckelord :Tensors; General relativity; Einstein s field equations; Cosmology; Friedmann s equation; FLRW-spacetimes; Tensorer; Allmän relativitetsteori; Einsteins fältekvationer; Kosmologi; Friedmanns ekvation; FLRW-rumtider;

    Sammanfattning : Cosmology is the study of the universe as a whole, and attempts to describe the behaviour of the universe mathematically. The simplest relativistic cosmological models are derived from Einstein's field equations with the assumptions of isotropy and homogeneity. LÄS MER
