Universe, Stars, and Galaxies: A Cosmic Journey

Spectra

Isaac Newton discovered that sunlight, when incident on a glass prism, decomposes into colored stripes. This rainbow is called the spectrum of light. Technical improvements revealed black lines within the spectrum. The Sun, being the nearest star, provides a light spectrum that offers information about its elemental composition. By comparing the black lines in the Sun’s spectrum with those of hydrogen and helium, we can conclude that the Sun’s outer layers are primarily composed of these

Understanding Obedience: Miller, Huemer, and Political Authority

Understanding Obedience: Miller and Huemer’s Perspectives

While Miller focuses on why the state is necessary for society to function well, Huemer is more interested in understanding why people actually obey political authority in the first place.

David Hume: Empiricism, Knowledge, and Causality

Hume’s Theory of Perceptions: Impressions and Ideas

David Hume categorizes perceptions (any mental content) into two types. Firstly, impressions are the direct feelings or sensations that occur because of a phenomenon; they come from our external senses.

The primary difference between them lies in their degree of force and vivacity; impressions are stronger and more vivid than ideas.

Antiepileptic Drug Therapy: Management and Side Effects

Understanding Antiepileptic Treatment Challenges

Antiepileptic Drug Therapy Goals

The primary objective of antiepileptic drug therapy is to suppress neuronal activity sufficiently to prevent hyperactivity. This aims to
