Metaphysics: An Introduction

The term *metaphysics* was coined by students of Aristotle. The literal meaning was "after the physics." Metaphysics is the branch of philosophy that addresses basic questions about the nature of reality.

Determinism and Freedom

According to determinism, everything that happens is determined by prior causes. The state of the universe at any moment could not be otherwise. One implication of this view is that all future states of the universe are, in principle at least, completely predictable. The principle that every event is caused is known as the *causal principle*. It is presupposed in science in everyday life. Most of the astonishing progress that science has made over the past four centuries has been made on the...

1. Why Study Programming Language Concepts?

• Expressiveness: Leverage diverse language features

• Selection: Match language to task (e.g., LISP for AI, PHP for web)

• Learning: Foundations ease uptake of new languages

• Efficiency: Choose constructs (recursion vs. iteration) for performance

• Maintenance: Better code reuse and understanding

2. Programming Domains and Typical Languages

3. Language Categories

• Imperative: Variables + assignment + iteration (C, Java, Python, Perl)

• Functional: Computation

Carbohydrates: Structure and Classification

Classification

• Monosaccharides: Single sugar unit (e.g., glucose, fructose).
• Disaccharides: Two sugar units joined (e.g., sucrose = glucose + fructose).
• Polysaccharides: Many sugar units linked (e.g., starch, glycogen).

Aldose vs. Ketose

• Aldose: Contains an aldehyde (-CHO) group (e.g., glucose).
• Ketose: Contains a ketone (>C=O) group (e.g., fructose).
• Number of Carbons: Triose (3C), Tetrose (4C), Pentose (5C), Hexose (6C).

Structural vs. Stereoisomers

• Structural Isomers: Same molecular formula, different bonding patterns or structure.
• Stereoisomers: Same connectivity, different spatial arrangement of atoms.

Chiral Carbons

• Chiral Carbon: A carbon atom bonded to four different groups, creating an asymmetric center.

The 9/11 Attacks and the Ensuing War on Terror

On the morning of September 11, 2001, the world experienced a profound shift. Terrorists hijacked four airplanes, resulting in the deaths of nearly 3,000 people. This catastrophic event was a deeply shocking moment for the United States and the international community.

The "War on Terror" refers to the comprehensive military and political responses initiated by the United States following the 9/11 attacks. This global campaign commenced with the war in Afghanistan and later expanded to include the war in Iraq, alongside numerous other operations aimed at combating terrorism worldwide. Understanding this period is crucial for comprehending the significant transformations in U.S. foreign policy and... Continue reading "9/11's Enduring Impact: U.S. Policy and the War on Terror" »

Classifying Matter

• Pure Substance: Element or compound.
• Mixture: Homogeneous (uniform) or heterogeneous (non-uniform).
• Element: One type of atom.
• Compound: Two or more atoms chemically bonded.

Properties of Matter

• Physical: Observable without changing the substance (e.g., color, density).
• Chemical: Describes the potential for a substance to change (e.g., reactivity).
• Physical Change: No new substance is formed (e.g., melting).
• Chemical Change: A new substance is formed (e.g., burning).

Atomic Structure

Protons, Neutrons, Electrons (PEN)

• Protons: Positive charge (+1), located in the nucleus.
• Neutrons: No charge (0), located in the nucleus.
• Electrons: Negative charge (-1), located in shells around the nucleus.
• PEN Relationships:
  • Protons = Atomic number.
  • Neutrons
