1. Introduction Many of us have seen this almost reflexive scene in movies and TV shows: the electrocardiogram (ECG) on the monitor suddenly becomes a straight line; the atmosphere freezes, the doctor shouts, and the defibrillator is brought in; "Clear!"—after the shock, the ECG waveform miraculously returns to normal…
1. Starting with the Black and White Keys: The Smallest Structural Unit of the Musical System. In a previous article (see: The Awakening of Sound - Basics (Part 1): Pitch Structure and Auditory Stability), I mentioned an important fact: the fifth interval describes the auditory proximity or distance between pitches. For example, C and…
1. The immediate reason for writing this article, when stability begins to require maintenance, is that a cross-border transit service provider I've relied on for a long time (which I've always considered the most technically professional) recently went bankrupt, causing my access architecture, which had been running stably for years, to suddenly fail. This change forced me to…
1. A Huge Pitfall Encountered When Logging into Telegram on a New iPad Recently, considering I no longer needed mobile work, I sold my unused M1 MacBook Pro and iPad mini 6 on Zhuanzhuan (a second-hand marketplace app): Then, I added some money and exchanged them for cellular versions with national subsidies…
1. Control Issues Regarding WordPress Email Notifications Most WordPress website users are probably familiar with WordPress's email notification feature. Whether it's automatic core version upgrades, automatic plugin upgrades, or notifications about new site updates…
1. Before discussing low, mid, and high notes, many music lovers have likely pondered this question: Is my voice low, mid, or high? This question seems simple, and it even appears that a simple vocal range test could provide the answer: how high can I sing…
1. Introduction Actually, I've wanted to write an article about iptables for a long time. Although I don't use it regularly, every time I do need to use it, I find that I've completely forgotten the relevant knowledge and have to go through it all again. This is because I've learned a certain knowledge point without reinforcing it through writing…
Most people ignore the variables in life
Life is actually more like an extremely complex and constantly changing equation, full of variables: the times, environment, family, opportunities, health, cognition, personality, choices, and even luck. And these variables are not simply added together, but rather influence and constrain each other.
Many people like to understand life as a linear "input-output" relationship, as if as long as you put something in, you will definitely get the corresponding result.
For example, some people believe, "As long as you work hard enough, you will definitely succeed." But they often overlook the fact that success never exists in isolation from the environment. The same effort can yield vastly different results in different eras, on different platforms, and with different resources: some people ride the wave of opportunity and rise to prominence, while others waste their lives struggling against headwinds. Effort is certainly important, but it is only one variable, not a universal formula that determines everything.
For example, some people believe that "working hard to make money when you're young will ensure happiness in your old age." However, the problem is that no one can be certain they will smoothly reach that "old age." In fact, many times, it's precisely because of long-term overworking, sacrificing health, and mentally exhausting oneself in youth that the body collapses prematurely. Thus, before one even has a chance to enjoy the future, they have already lost the ability to face it.
Often, reality is not a stable assembly line; it's more like a dynamic system—variables are constantly changing, conditions can be reset at any time, and formulas that held true in the past may not hold true in the future. Many seemingly self-evident life logics are essentially just phased experiences under specific circumstances, rather than universally applicable truths.
Therefore, what people truly need is perhaps not to cling to a fixed formula for life, but to always maintain a sense of awe for "variables." Knowing that life cannot be absolutely controlled, and understanding that many things cannot be achieved simply by "trying" or "planning."
This realization is not pessimistic; on the contrary, it means that a person begins to truly understand the complexity of reality, and therefore understands better how to maintain balance, exercise restraint, and cherish the present moment.
And only then can one truly understand the meaning of the phrase "life is unpredictable".
1. From Pitch Names to Solfège: Why Singing Requires a Different Perspective In a previous article (see: The Awakening of the Voice - Basics (Part 1): Pitch Structure and Auditory Stability), I introduced a fundamental fact of the modern vocal system: sound does not exist randomly. Starting with overtone structure, a certain…
1. Why did I write this article? The purpose of this article is not to create a vocal tutorial, nor is it a complete overview of music theory. It's more like a record of my own reflections—an attempt to answer a simple yet complex question: What am I actually listening to? And why are these sounds perceived by me in this way…
