Chapter 1: The Beauty of Chemical Equilibrium

In chemistry, the idea of equilibrium, symbolized by the ? sign, illustrates balance. This representation consists of two arrows of equal length, placed horizontally and pointing in opposite directions.

Essentially, chemical equilibrium signifies a state where, under certain conditions—like temperature and pressure—the reactants and products remain unchanged over time.

Philosophically speaking, it suggests that with adequate support, a system can maintain its balance and stability. I’ve always found this concept particularly captivating, as it embodies resilience and strength, showcasing how robust a system can truly be.

Another key principle to consider is Le Chatelier’s Principle, which explains how equilibrium adjusts in response to changes. Variations in temperature, pressure, volume, or concentration lead to the emergence of a new equilibrium. For me, the most significant takeaway from this principle is that equilibrium inherently accommodates change.

The first video, "My First Tattoo At Age 64," explores the personal journey of getting a tattoo later in life, emphasizing the significance of change and self-expression.

Reflecting on how systems respond to stress prompts introspection. If I have the right conditions—like supportive friends and a nurturing environment—I can maintain my equilibrium. However, when circumstances shift, I must find a new way to balance my life.

I tend to romanticize past experiences and struggle with accepting change. The concept of equilibrium serves as a poignant reminder, captured in my tattoo—a symbol of how my circumstances can either empower or challenge me, and an acknowledgment that change is a vital part of growth. This is all represented by two simple lines on the back of my neck.

Throughout my engineering studies, I encountered other symbols that resonate deeply with me, potentially future tattoos. For instance, the electrical symbol for a diode, represented by a simple triangle, functions as a one-way switch for current. It allows current to flow in only one direction, symbolizing that life only permits us to move forward—there’s no point in trying to revert to the past.

Similarly, in mathematics, it’s customary to conclude proofs with "Q.E.D.," an abbreviation for the Latin phrase quod erat demonstrandum, meaning "which was to be demonstrated."

One of my greatest joys was writing this after completing a complex proof. It felt rewarding to look back on pages filled with chaotic thoughts and moments of doubt, only to arrive at a concise and satisfying Q.E.D. (which conveys that everything will eventually fall into place, even amid uncertainty).

Chapter 2: The Philosophical Nature of Tattoos

I cherish the stories behind meaningful tattoos, and I was pleasantly surprised to discover that many of these narratives are embedded in my math and science textbooks. It seems that numerous mathematicians and scientists also ventured into philosophy. Perhaps it’s true that those in search of truth—whether through mathematics, science, or philosophy—are not so different after all.
