This abstract describes a control system for a 3 horsepower (3hp) alternating current (AC) motor that operates in both forward and reverse directions with a delay of 2 seconds using two limit switches. The system is designed to ensure the safety of the motor and surrounding equipment by introducing a delay before the motor changes direction, and by using two limit switches to control the direction of the motor. When the motor runs in the forward direction and the (...) first limit switch is triggered, the motor is stopped for a period of 2 seconds before it changes direction to reverse. When the motor runs in the reverse direction and the second limit switch is triggered, the motor is stopped for a period of 2 seconds before it changes direction to forward. The control system uses a motor controller to regulate the motor's speed and direction, and two limit switches to control the motor's direction and ensure its safe operation. This system is suitable for use in industry. When the motor runs in the forward direction and the limit switch is triggered, the motor is stopped for a period of 5 seconds before it changes direction to reverse. The control system uses a motor controller to regulate the motor's speed and direction, and a limit switch to trigger the reversal of the motor. The system is designed to ensure the safety of the motor and surrounding equipment by stopping the motor before reversing its direction, and by introducing a delay to allow the motor to come to a complete stop.

Genius Is Not About Popularity -/- Throughout history, the concept of genius has often been misunderstood. Many equate genius with fame, believing that the most recognized figures in science, art, and philosophy are necessarily the greatest minds. However, true genius is not about popularity; it is about depth of insight, originality of thought, and contributions to human progress, regardless of public recognition. Some of the most brilliant minds were overlooked in their time, yet their ideas shaped the future. This essay (...) explores why genius is independent of popularity and how history has proven that true intellectual greatness often transcends societal recognition. -/- The Nature of Genius -/- Genius is characterized by extraordinary intellectual ability, creativity, and the capacity to think beyond conventional wisdom. A true genius is not necessarily someone who seeks attention or public validation but someone who pursues knowledge and innovation for its own sake. Many geniuses are ahead of their time, which can result in their ideas being ignored or misunderstood. Unlike celebrities or influential public figures, a genius does not necessarily attract mass appeal because their work often requires a level of understanding that only a few can appreciate during their lifetime. -/- Unrecognized Geniuses in History -/- History is filled with examples of individuals whose genius was not recognized until long after their death. One of the most famous cases is Nikola Tesla, a brilliant inventor and engineer whose contributions to electrical engineering were largely overshadowed by more business-savvy figures like Thomas Edison. Tesla’s work on alternating current (AC) power revolutionized the world, yet he died in relative obscurity. -/- Another example is Gregor Mendel, the father of modern genetics. Mendel’s groundbreaking experiments with pea plants laid the foundation for genetic inheritance, yet his work was largely ignored during his lifetime. It was only decades later that scientists realized the significance of his discoveries, which are now fundamental to biology. -/- Similarly, Vincent van Gogh is celebrated today as one of the greatest painters in history, yet he sold only a few paintings during his lifetime. His artistic vision was not widely appreciated, and he struggled with poverty and mental illness. His posthumous fame is a testament to how genius is often ahead of its time and only recognized when society catches up with its vision. -/- The philosopher Søren Kierkegaard, who laid the foundation for existentialist thought, was largely dismissed during his lifetime. Today, his writings influence fields as diverse as philosophy, psychology, and theology. Similarly, Ada Lovelace, who worked on Charles Babbage’s early mechanical computer, was virtually unknown during her time but is now recognized as one of the first computer programmers. -/- Alan Turing, whose work in cryptography helped end World War II, was largely unrecognized in his lifetime due to prevailing social prejudices. His contributions to computer science and artificial intelligence were only widely acknowledged decades after his tragic death. Likewise, the works of Emily Dickinson, now considered some of the greatest poetry in American literature, remained unpublished until after her passing. -/- Another overlooked genius was Hypatia of Alexandria, a pioneering mathematician, astronomer, and philosopher in ancient Greece. Despite her immense contrib”tions to science and philosophy, she was largely erased from history due to political and religious turmoil. Similarly, Joseph Priestley, the scientist who discovered oxygen, did not receive immediate recognition because his findings conflicted with mainstream scientific beliefs at the time. -/- Another modern example is Rosalind Franklin, whose work in X-ray crystallography was crucial to the discovery of DNA’s double helix structure. However, her contributions were overshadowed by Watson and Crick, who received most of the credit for the discovery. Additionally, Ignaz Semmelweis, a 19th-century physician who introduced handwashing in medical practice to prevent infections, was dismissed and ridiculed during his time, only for his ideas to become foundational in modern medicine. -/- Other overlooked geniuses include Ludwig Boltzmann, who developed statistical mechanics, a cornerstone of modern physics. His work was dismissed by many during his lifetime, leading to his tragic death. Similarly, Emmy Noether, one of the greatest mathematicians in history, made groundbreaking contributions to abstract algebra and theoretical physics but was largely unrecognized due to gender biases. -/- Johan Sebastian Bach, now considered one of the greatest composers, was not widely appreciated during his lifetime and was overshadowed by more fashionable composers of his era. Likewise, Henri Poincaré, whose work in mathematics and theoretical physics laid the groundwork for chaos theory and relativity, was often overlooked in favor of his contemporaries. -/- Popularity vs. Impact -/- Popularity is often dictated by trends, media influence, and societal values, whereas genius is about intellectual contribution and long-term impact. Many popular figures may gain widespread recognition due to charisma, marketing, or entertainment value, but that does not necessarily mean they have made groundbreaking contributions to human knowledge. In contrast, some of the most transformative ideas in science, philosophy, and art have come from individuals who were not widely known in their era. -/- Moreover, some geniuses actively avoid the spotlight, preferring to focus on their work rather than public recognition. Albert Einstein, despite becoming famous later in life, initially worked in obscurity as a patent clerk before his theories revolutionized physics. Similarly, mathematician Srinivasa Ramanujan made astonishing contributions to number theory without formal education or widespread recognition during his lifetime. -/- The Importance of Recognizing True Genius -/- While popularity can bring attention to ideas, it is important to differentiate between recognition and true intellectual brilliance. Society should strive to support and acknowledge innovative thinkers even if their ideas are not immediately understood or appreciated. Educational institutions, scientific communities, and cultural organizations have a responsibility to foster environments where unconventional ideas can thrive, ensuring that genius is recognized based on merit rather than mass appeal. -/- Conclusion -/- Genius is not about popularity; it is about profound intellectual contributions that shape the world. Many great minds were overlooked in their time, only to be celebrated long after their deaths. History shows that true genius often works in obscurity, pushing the boundaries of knowledge regardless of societal recognition. Instead of equating fame with intelligence, we should value deep thinking, innovation, and originality, ensuring that future generations recognize and support those who truly advance human understanding. -/- .

When it comes to contentious conversations, the call for civility is commonplace. Rarely do we hear a call for nonviolence in communication. This is unfortunate, since nonviolence is a better standard than civility (a standard I critiqued in part one of this three-part series). Part of the problem is that a framework for communicative nonviolence has not (to my knowledge) been fully developed. Mohandas (“Mahatma”) Gandhi, the “father of nonviolence,” is widely known for nonviolence, but primarily in the realm of (...) noncommunicative action. However, there is a natural line of development in that direction from elements in his thought: Gandhi derives his commitment to nonviolence ("ahimsa" in Sanskrit) from his "law of Truth," which directs us to follow “Truth in thought, Truth in speech, and Truth in action." Inspired by Gandhi among others, Marshall B. Rosenberg developed what he termed "Nonviolent Communication" (NVC). Valuable though NVC is, it is most applicable to particular conversational contexts. It is but one part of a broader nonviolent framework, which I’ll call "ahimsic communication" (AC) to distinguish it from NVC. In this second installment of the series, I develop a framework for AC.

This review places this translation and commentary on Book A of Prior Analytics in historical, logical, and philosophical perspective. In particular, it details the author’s positions on current controversies. The author of this translation and commentary is a prolific and respected scholar, a leading figure in a large and still rapidly growing area of scholarship: Prior Analytics studies PAS. PAS treats many aspects of Aristotle’s Prior Analytics: historical context, previous writings that influenced it, preservation and transmission of its manuscripts, (...) editions of its manuscripts, interpretations, commentaries, translations, and its influence on subsequent logic, philosophy, and mathematics. All this attention is warranted because Prior Analytics marks the origin of logic: the field that, among other things, asks of a given proposition whether it follows from a given set of propositions; and, if it follows, how we determine that it follows; and, if it does not follow, how we determine that it does not follow. This translation and commentary is not suitable for use in an undergraduate course. It has too many quirks that the teacher would want to warn against. A copy editor should have dealt with these things and with other matters such as incorrect punctuation and improper end-of-line divisions. The prose is heavily laden with glaring clichés. The one-page preface contains “longer than I care to remember”, “more than I can possibly list here”, “first and foremost”, and “last and by no means least”—a sentence later is devoted to thanking the “incredibly meticulous and helpful copy-editor”. A few pages later the translator reveals the need “to find a path between the Scylla … and the Charybdis …”. Moreover, the index is far from meeting the needs of undergraduate students. The attention to scholarly detail is not what one hoped for from Oxford University Press. At 26b10-15, this translation reads “let swan and white be chosen as white things” for what Smith correctly translates “let swan and snow be selected from among those white things”. At 41b16, “angles AB and CD” should read “angles AC and BD”. Despite this book’s flaws, it will be found useful if not indispensable for those currently engaged in Prior Analytics studies. The alternatives suggested to Robin Smith’s translation choices are often worth consideration. It is to be emphasized, however, that this book is unsuitable for those entering Prior Analytics studies. (shrink)

In parts one and two of this three-part series, I developed a framework for ahimsic (nonviolent) communication (AC) as an alternative to the standard communicative norm of civility. The framework presented for AC offers various categories of resistance to violence, including nonviolent forms of negotiation, compromise, protest, verbal force, verbal distraction, argumentation, and communicative satyagraha (Gandhian nonviolence applied to communication). I also provided a range of real-life examples of successful AC resistance, including the stories of Derek Black, Daryl Davis, James (...) Lawson, and Antoinette Tuff. These examples demonstrate that AC “works” even against neo-Nazis, KKK grand wizards, angry punch-throwing bikers, and active school shooters. In this third and final installment, I will explain why AC works—better than any form of violent communication (VC). My main claim is that AC derives strategic power from its moral power. As various components of my argument are drawn from the nonviolence tradition more generally, what follows will double as a primer on the morality of nonviolence. However, we will also see significant differences in how we must adapt nonviolent strategy and morality to the case of communication. (shrink)
