This set of notes clearly explains everything you need to understand about light, quantum theory, and atomic models for chemistry and physics exams. It covers how light behaves both as a wave and as a particle, the meaning of wavelength, frequency, and amplitude, and how they relate through the speed of light equation. The notes also include the full electromagnetic spectrum from gamma rays to radio waves, showing how energy and frequency increase together, along with worked examples such as cal...

Macromolecules (carbohydrates, lipids, proteins, nucleic acids) are the large, complex molecules necessary for life.  • Lipids: non-polar/hydrophobic molecules including fats/oils, waxes, phospholipids, steroids. Fats store energy; phospholipids form membranes; steroids (e.g., cholesterol) play structural and signalling roles.  • Proteins: made of amino acids (20 common types), linked by peptide bonds to form polypeptides. Proteins have four levels of structure (primary, secondar...

Carbon has a unique role in biological molecules because of its ability to form four covalent bonds, enabling complex structures and functional groups.  • Important elements for life include carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur; they combine to form nucleic acids, proteins, carbohydrates, lipids.  • Functional groups (hydroxyl, carbonyl, amino, phosphate, etc) define chemical behavior of macromolecules.  • Water and its properties (polarity, hydrogen bon...

Biology is the science of life: studying living organisms, their parts and processes, and how they interact with each other and the environment.  • Living things share key properties: order/organization, response to stimuli, reproduction, growth & development, regulation/homeostasis, energy processing, adaptation via evolution.  • Organisms are organized in hierarchical levels (atoms → molecules → organelles → cells → tissues → organs → organ systems → organisms) an...

This essay supports the central purpose of the liberal arts as a means of intellectual and moral liberation. It argues that true education goes beyond job training it empowers individuals to think critically question injustice and understand the human condition drawing on philosophical perspective, and modern educational debates, the paper defense, the continuing relevance of the liberal arts in shaping free, creative and socially conscious thinkers
