"The valve aspect of a vacuum tube is merely a byproduct; its chief function is to rectify alternating current."

This quote emphasizes that while the valve property of a vacuum tube (an early electronic device) is a notable feature, its primary purpose lies in its ability to convert alternating current (AC) into direct current (DC), which is essential for many electrical applications at the time when Fleming made this statement. The rectification of AC current was indeed the "chief function" of the vacuum tube, making it indispensable in early radio and telecommunications technology.

"It is a great pleasure to find Nature working on lines so similar to those which we have devised ourselves."

This quote by John Ambrose Fleming expresses a sense of admiration for nature's intricate design, suggesting that it often mirrors our own inventions. It underscores the idea that scientific discoveries and technological innovations may be rooted in the natural world and its inherent principles, thus emphasizing both mankind's intellectual achievements and the harmonious relationship between humans and nature.

"When we set out to solve a problem, it is often of advantage to let our minds rest from it for a time, and then come back fresh to the attack."

The quote suggests that taking a break from a problem or challenge can sometimes be beneficial in finding a solution. By stepping away and allowing your mind to rest, you may return with a fresh perspective, leading to innovative ideas and potential solutions. This approach is often effective because it allows the subconscious mind to process information, making new connections that might not have been apparent during focused, continuous effort.

"The progress of invention, therefore, appears to rely on men who are driven not by the immediate hope of profit but the eternal itch of curiosity."

This quote by John Ambrose Fleming suggests that technological advancements or "the progress of invention" is primarily fueled by two motivations: the pursuit of profits, which drives industrial innovation, and the insatiable curiosity of individuals, which drives fundamental scientific discovery. He implies that those driven by the latter, often called "curiosity-driven research," are essential for long-term technological growth as they seek knowledge without immediate financial gain, but rather for the satisfaction of understanding the world around them. This eternal itch of curiosity serves as the foundation for many breakthroughs and innovations that lay the groundwork for future progress.

"It is often better to have a rough answer to the wrong question than an exact answer to the wrong problem."

This quote by John Ambrose Fleming highlights the importance of asking the right questions rather than getting lost in the pursuit of answers, even if they are technically correct. Sometimes, it's more valuable to focus on identifying the actual problem or question at hand, instead of diligently searching for a solution to an issue that may not be relevant. In other words, having a 'rough answer' to the correct question can often lead to more productive results than having an exact answer to a misguided one.
