This thesis attempts to explain Everettian quantum mechanics from the ground up, such that those with little to no experience in quantum physics can understand it. First, we introduce the history of quantum theory, and some concepts that make up the framework of quantum physics. Through these concepts, we reveal why interpretations are necessary to map the quantum world onto our classical world. We then introduce the Copenhagen interpretation, and how many-worlds differs from it. From there, we dive into the concepts of entanglement and decoherence, explaining how worlds branch in an Everettian universe, and how an Everettian universe can appear as our classical observed world. From there, we attempt to answer common questions about many-worlds and discuss whether there are philosophical ramifications to believing such a theory. Finally, we look at whether the many-worlds interpretation can be proven, and why one might choose to believe it.
The purpose of this paper is to provide an analysis of entanglement and the particular problems it poses for some physicists. In addition to looking at the history of entanglement and non-locality, this paper will use the Bell Test as a means for demonstrating how entanglement works, which measures the behavior of electrons whose combined internal angular momentum is zero. This paper will go over Dr. Bell's famous inequality, which shows why the process of entanglement cannot be explained by traditional means of local processes. Entanglement will be viewed initially through the Copenhagen Interpretation, but this paper will also look at two particular models of quantum mechanics, de-Broglie Bohm theory and Everett's Many-Worlds Interpretation, and observe how they explain the behavior of spin and entangled particles compared to the Copenhagen Interpretation.
Activists seeking to create social change must decide whether to expend more resources trying to change the behavior of individuals or institutions. For example, a climate activist could spend their days urging people to stop flying in airplanes, or they could spend their days urging the government to outlaw excessive flying. Some social change theorists argue that the second tactic is more effective than the first. Are they correct? I use the environmental movement and the animal liberation movement as case studies to examine this question from an empirical perspective. I conclude that while attempts to change individual behavior should not be entirely abandoned, they should be used with caution because of their tendency to distract the public from the need for institutional reform and their tendency to alienate potential allies. Seeing that, for decades, the animal movement’s main strategy has been to urge individuals to change their dietary behavior, this movement would greatly benefit from this knowledge.
