Introduction
Electronics technology requires a working knowledge that goes beyond playing video games or using Windows 10—it’s about understanding how devices work and how to build or fix them. I’ve been in electronics since 1970, building projects like a plasma discharge tube for a 1977 science fair, and I’ve seen how technology has transformed the field, from tubes to solid-state circuits. I believe science should be based on evidence, not speculation, and that practical knowledge is key. This page explores the level of knowledge you need for electronics, drawing on my experience and the role technology plays in advancing the field.
Aptitudes for Electronics
Success in electronics often depends on natural aptitudes, as outlined in Howard Gardner’s Multiple Intelligences—though I prefer the term “aptitudes” over “intelligences.” Two key aptitudes are spatial and logical-mathematical. Spatial aptitude is the ability to visualize things you can’t see, like mentally tracing current flow in a circuit. For example, when I built a circuit for a science fair, I could picture how charged particles moved in a discharge tube, even though I couldn’t see them, and adjust my design accordingly.
Logical-mathematical aptitude involves numbers, logic, and problem-solving, which goes hand-in-hand with spatial skills in electronics. A technician might use these to troubleshoot a circuit—reading an electrical diagram, which is like a detailed blueprint, to find a fault. Engineers often rely more on advanced math for design, while hobbyists might focus on small projects, like building a simple LED circuit. These aptitudes are largely innate, but they can be honed with practice and the right education.
Building Foundational Knowledge
The level of knowledge you need in electronics depends on your goals—whether you’re aiming to be a technician, engineer, or hobbyist—and your prior education. If you’re starting out, I recommend community college courses in chemistry and physics to understand the basics, like how electrons behave in circuits. Math through at least algebra 2 and trigonometry is essential for calculations, such as determining resistor values or timing in circuits. About 80% of U.S. community colleges offer electronics-related programs, so these courses are widely accessible.
For programming, focus on languages that give you low-level control, like C, C++, or assembly, which are better for electronics than high-level languages like Python. Python, often used with the Raspberry Pi, isn’t ideal for direct hardware control because it lacks the precision needed for timing-critical tasks. Instead, consider microcontrollers like Arduino, which I’ve used for projects—they’re better suited for electronics. Learning Linux can also help, especially for managing hardware systems efficiently.
Technology’s Role and Practical Challenges
Technology has revolutionized electronics, just as it has other fields. In the 1970s, Paul Ehrlich predicted overpopulation would cause famine, but he missed how the Green Revolution—new farming technologies—fed billions. Similarly, electronics advanced from bulky tubes to compact solid-state circuits, a transition I witnessed firsthand, enabling smaller, more efficient devices. To work in this field, you need hands-on knowledge to leverage these advancements, whether you’re wiring a system as a technician or building a hobby project.
But acquiring this knowledge isn’t always easy, and speculative ideals can mislead. I’ve experimented with “green” farming, trying organic, non-GMO methods, but found they reduced yields and weren’t practical—modern tools like gas tillers and fertilizers are more effective, just as technology drives progress in electronics. Learning electronics requires a practical mindset: focus on what works, like understanding circuits through real-world projects, not chasing abstract theories or tools that don’t fit the task. Nature is resilient, and so is human ingenuity—we adapt and improve through evidence-based knowledge, not speculation.
Conclusion
Electronics technology demands a mix of natural aptitudes—like visualizing circuits and solving problems logically—and foundational education in math, science, and practical programming. Whether you’re a technician, engineer, or hobbyist, the level of knowledge you need depends on your goals, but hands-on experience is key. Technology has shaped electronics, just as it has other fields, and a practical approach—grounded in evidence, not speculative ideals—ensures you can harness its benefits. Focus on what works, and you’ll build the skills to succeed in this ever-evolving field.

Reason, Science, and Pragmatism: A Deist’s Critique
As a deist from Bristol, Virginia, I advocate for reason and the scientific method over ideological dogma, especially in public policy and environmental debates. My writings challenge the misuse of science and mystical narratives, promoting practical solutions grounded in evidence.
The scientific method is a cornerstone of rational inquiry, yet it’s often distorted in policy. In The Scientific Method and Its Misuse in Public Policy, I argue that cherry-picking data to push agendas—like restrictive regulations—undermines science’s integrity. True science demands skepticism, not conformity to political or religious narratives.
This is further explored in A Scientific Method: Foundations and Limits, where I outline its reliance on testable hypotheses and reproducible results. The method’s limits—its inability to address metaphysical questions—highlight why deism complements science, positing a purposeful universe without requiring unprovable miracles.
Environmental policy often strays from this rigor. In Rational Farming vs. Eco-Religious Dogma, I critique eco-ideologies that prioritize mystical views of nature over human needs. Industrial farming, while imperfect, feeds billions; romanticized organic methods often fail to scale, ignoring practical realities.
Climate change debates suffer similar distortions. In Taking a Sober Non-Mystical View on Climate Change, I argue that apocalyptic predictions often exaggerate impacts, sidelining adaptation and innovation. For instance, CO2 Boosts Plant Growth, Not Apocalypse shows how elevated CO2 levels enhance crop yields, a fact often ignored by alarmist narratives.
Extreme environmentalism can harm vulnerable populations. In Green Theology is Killing Children: Nature Has Rights?, I highlight how prioritizing “nature’s rights” over human welfare—like restricting energy access in developing nations—exacerbates poverty and mortality. Reason demands balancing ecological goals with human survival.
Pragmatic solutions exist. In Turning Ocean Water, Plastic Waste into Food, Water, and Jobs, I explore innovative desalination and waste recycling to address food and water scarcity, creating jobs without dogmatic constraints. Similarly, Stretching Your Dollar: Feeding Yourself on a Budget offers practical tips for affordable nutrition, emphasizing resourcefulness over ideology.
My deist perspective, detailed in Deism, Science, and Reason: A Rational Perspective, sees nature as a purposeful system governed by discoverable laws, not a deity requiring worship. This view rejects both religious and eco-religious dogmas, advocating for policies grounded in evidence and human welfare.
From Bristol to global debates, I critique the misuse of science as a tool for control, whether through fear-driven climate policies or restrictive regulations. By blending deism, skepticism, and practical solutions, my work encourages rational dialogue that respects nature’s order while prioritizing human needs.
