UNDERSTANDING PHYSICS – Part 1
MOTION, SOUND & HEAT
Isaac Asimov
Motion, Sound, and Heat
From the ancient Greeks through the Age of Newton, the problems of motion, sound, and heat preoccupied the scientific imagination. These centuries gave birth to the basic concepts from which modern physics has evolved. In this first volume of his celebrated UNDERSTANDING PHYSICS, Isaac Asimov deals with this fascinating, momentous stage of scientific development with an authority and clarity that add further lustre to an eminent reputation. Demanding the minimum of specialised knowledge from his audience, he has produced a work that is the perfect supplement to the student’s formal textbook, as well se offering invaluable illumination to the general reader.
ABOUT THE AUTHOR:
ISAAC ASIMOV is generally regarded as one of this country's leading writers of science and science fiction. He obtained his Ph.D. in chemistry from Columbia University and was Associate Professor of Bio-chemistry at Boston
University School of Medicine. He is the author of over two hundred books, including The Chemicals of Life, The
Genetic Code, The Human Body, The Human Brain, and The Wellsprings of Life.
The Search for Knowledge
From Philosophy to Physics
The scholars of ancient Greece were the first we know of to attempt a thoroughgoing investigation of the universe--a systematic gathering of knowledge through the activity of human reason alone. Those who attempted this rationalistic search for understanding, without calling in the aid of intuition, inspiration, revelation, or other non-rational sources of information, were the philosophers (from Greek words meaning "lovers of wisdom").

Career Researsch Paper

...Research Paper Part I: Physics strives to identify fundamental principles governing the build and deportment of matter, the engenderment and movement of energy, and the interaction of matter and energy. Some physicists use those principles in theoretical areas, such as the nature of time and the beginnings of our universe, while some work in practical areas such as the development of advanced materials, optical and electrical devices, and medical equipment (BLS, para. 2). I chose physics for my career research paper because I have an intellectual curiosity for the world, the universe, and everything in between. I want to understand how matter moves through spacetime, and how the universe behaves. Understanding physics also means understanding many other scientific areas of study, thus providing an intimate knowledge for reality as we know it. Many physicists work in laboratories, where they design and perform experiments with sophisticated equipment. Some of that equipment includes lasers, particle accelerators, electron microscopes, and mass spectrometers. Although much research may be conducted through experiments in the lab, physicists still spend much time in offices planning, recording, analyzing, and reporting on research. Many who are deeply involved in research way also work very long or irregular hours. For basic research positions, independent research in industry, faculty positions, and advancement to managerial positions, a Ph.D in physics or related......

A Little Concept Called Creation

...Davies’ G-d and the new physics I have learned otherwise. In the section’s I read, I found that while the book tended to get a bit intellectual and less college friendly, certain topics produced a yield that was really unlike anything I’ve read before. It should be put out there prior to diving into discussion topics that obviously two schools of thought will be presented, the sciences and the religious. The following are two almost definitions given by Davies: “Science is based on careful observation and experiments enabling theories to be constructed which connect different experiences. Central to this approach is the willingness of the scientist to abandon a theory if evidence is produced against it…Religion is founded on revelation and received wisdom. Religious dogma that claims to contain an unalterable Truth can hardly be modified to changing ideas. The true believer must stand by his faith whatever the apparent evidence against it is. (6) It is by these two definitions that most of this paper will be centered around, and very important that everyone who reads this knows how I have defined these topics and those who subscribe to them. “…Any system of thought that claims to provide an understanding of the physical world must make some statement about the origin of the world.” (7) It is with that thought I would suggest that there is very strong importance and continuing relevance of the religious concept “creation” both in the secular (science) world and the......

Physics

...Professor PHYS 2010 October 21, 2014 Physics in Our Daily Activities Physics is a very important science that can almost be found anywhere in our lives. Many people find this statement hard to believe because they are not able to see the basic aspects of physics all around them. I personally think that unless the person is a physicist or at least someone who had some physics classes, chances are this person or someone is not going to understand how much physics affects our daily life. The significant effect of physics on us today can be easily seen when looking at our reliance on modern technology. Many of the technologies that are changing the world around us are based on physics principles. Physics is more than a subject we study in class, it is also a powerful tool that can help us to gain a better understanding of the everyday world. Physics can be seen in a lot of simple games that we play all the time. One of my favorite games that I almost play on a daily basis is pool. The physics associated with pool is mainly about the collisions between the pool balls. When two pool balls hit each other or collide the collision between them is known to be an elastic collision. According to Billiards in the Classroom, "elastic collisions are collisions in which both momentum and kinetic energy are conserved. The total system kinetic energy before the collision equals the total system kinetic energy after the collision." Therefore, we can assume that the collisions that......

...(2011). “Effects of Instruction on Students’ Expectations in College Physics.” An Undergraduate Thesis, College of Education, West Visayas State University, Iloilo City II. Summary: The experimental study scrutinized the effects of instruction on student’s outlook in College Physics. The subjects of the study were the second year college students taking up Bachelor of Science in Biological Science who were enrolled in College Physics in West Visayas State University for the school year 2010-2011. The researchers identified the teacher’s instruction as the independent variable, and the dependent variable was the expectations of second year college taking up Bachelor of Science in Biological Science, taking into consideration their attitudes, beliefs, and assumptions about College Physics. The study utilized the one-group pretest – posttest design in an experimental study. A Likert-type scale instrument was used as a data gathering instrument. The analysis of data was shown on the descriptive data analysis with the use of the frequency and percentage. The researchers utilized t- Test to determine the significant difference in the expectations of second year students enrolled in college physics before and after teacher’s instruction. The findings of this study revealed the significant effects of instruction on students’ expectations in College Physics. The paper is beneficial to the students of College Physics in assessing and determining how their expectations......

Career Analysis: Video Game Programmer

...first establish myself in the industry as a programmer because design jobs are typically not entry-level and require more experience. Before planning the steps I will need to take to become a video game physics engine programmer I must first analyze the responsibilities of a video game programmer; specifically a physics engine programmer. “A physics engine programmer is responsible for determining the physics that will be utilized in a video game.” Realism games will strive to simulate the most accurate real-world physics that they possibly can, which requires the programmer to have a great deal of knowledge in many different aspects of physics as well as a great deal of calculus. Although, a lot of games will produce their own laws of physics that correlate with game's world they are applying them to, the physics engine programmer will still need to have a wide range of knowledge in physics to actually determine the physical laws in the world and how they interact with each other. It is not uncommon to see only one physics programmer assigned to a project when developing games that require less complex physics (example: role-playing games), but games that require more complex physics (example: war simulation games) will often require groups of physics programmers. The term “physics engine programmer” is very specific in the industry so their responsibilities/title can be closely related and could also fall in between that...

Supply Chain

...Physics (from Ancient Greek: φυσική (ἐπιστήμη) phusikḗ (epistḗmē) "knowledge of nature", from φύσις phúsis "nature"[1][2][3]) is the natural science that involves the study of matter[4] and its motion through space and time, along with related concepts such as energy and force.[5] One of the most fundamental scientific disciplines, the main goal of physics is to understand how the universe behaves.[a][6][7][8] Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy.[9] Over the last two millennia, physics was a part of natural philosophy along with chemistry, biology, and certain branches of mathematics, but during the scientific revolution in the 17th century, the natural sciencesemerged as unique research programs in their own right.[b] Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. New ideas in physics often explain the fundamental mechanisms of other sciences[6] while opening new avenues of research in areas such as mathematics and philosophy. Physics also makes significant contributions through advances in new technologies that arise from theoretical breakthroughs. For example, advances in the understanding of electromagnetism or nuclear physics led directly to the development of new products that have dramatically transformed modern-day society, such as television, computers, domestic appliances,......

Quality Tools

...Know the Laws. Use the Tools. Profit. Factory Physics® Principles for Managers—Fourth in a Series A series of articles designed to help managers and executives better control and optimize their operations through a solid understanding of the practical science that governs their environments. Managing Variability Variability is an unavoidable fact of life that is best managed through understanding the tradeoffs it presents. Variability is a double-edged sword—it can be good, e.g. having more than one product to offer to your customers, or variability can be bad, e.g. machine breakdowns or order cancellations. As an executive, your strategic solutions for managing variability in your environment are two fold: First, determine the amount of “good” variability that you require to be successful in your market and Second, determine the lowest cost combination of buffers (inventory, capacity and time) and efforts at reduction of “bad” variability to ensure you succeed in your market. For most manufacturing and supply chain managers, the luxury of setting demand levels and product offerings is not one of your options. However, Factory Physics principles provide practical scientific relationships such as the VUT equation and practical buffer management strategies for getting the best possible performance out of the operations in your span of control. In any case, the key to success is in understanding the effects of variability on value stream behavior and then managing the......

Material on Morality

...Professor Schiller World Philosophies 2 February 2013 Material on Morality Immanuel Kant was born in 1724 and grew up in the town of Konigsberg, from which he hardly stirred. Growing up in a family that emphasized the importance of education, discipline and religious devotion. He enrolled in the University of Konigsberg at age sixteen, and would spend his entire life working there. In his life, Kant pioneered philosophy by severing philosophies rootedness to the doctrines of radical enlightenment: materialism determinism, and atheism. He felt a great tension between the humanists’ emphasis on ‘the dignity of man’ and sciences reduction of human beings to ‘specks of dust’. His rejection of many Enlightenment philosophies and work to reconcile others resulted in the philosophies that rocketed philosophy far beyond the debate between rationalists and empiricists. I will explore Kant’s views on what knowledge is and what is possible to know, which I will then compare these views to those held by sceptics and dogmatists. Similarly, I will discuss how Kant’s deviating epistemology led to the formation of his categorical imperative and views on morality, contrasting this moral code to the ones of the Hellenistic schools of thought. Lastly, I will deliberate on how Kant’s categorical imperative is nonoperational with the 20th and 21st century’s understanding of psychology and quantum physics. Kant believed that our understanding of the external world was two-part,......

How Something Can Come from “Nothing”

...Conforming our beliefs to the evidence of reality is a hard transition for most. Unraveling the deep truths about our origins in this universe is confronting the very foundations of our society’s historic religious establishments. Could modern science bring us closer to a true pantheistic god of beauty, or destroy all notions of a sense of purpose (Krauss, 2012)? Regardless of your faith, the laws of physics are proving every day that something can come from nothing. A god of the gaps is probably the most common, as well as most elementary, argument for debating science vs. religion. This idea is simply employing a divine meaning to things that science has no answer to. It is often a question of why, and assumes purpose to everything. One thing that science cannot refute is a purpose to our world. It is scientifically inert, that is to say that there is no plausible way to test its predictions. The scientific method is just field testing the observable world we see around us. We are all naturally inquisitive; we thrive to find our “purpose” in the world. But this, I believe, is simply a limit to our senses. When there are questions that science cannot answer, such as why we came to be, skeptics often say that it is outside the bounds of our universe. This, to me, is just a lazy answer. The god of the gaps is a “fill in the blank” answer to everything that has been so far, untestable. This does not mean that anybody has the right to invoke a......

Conscious Mind over Matter

...known as a “unit.” Stemming from this idea that the conscious is independent from the physical realm, many questions remain unanswered concerning the plausibility of such technology. Furthermore, if this virtual reality technology was put in use, could the computerized units possess a conscious mind of their own, which is free of significant mental impairment? Holistically, Rusnak’s film challenges the basic principles on which physicalism was built by arguing that reality is a creation of the conscious mind, and therefore reality does possess many non-physical components. Mankind’s perception of reality is limited in scope to that which is visible and present around us. The same holds true when applied individually, since a person’s understanding of reality is a function of what the environment suggests is plausible. Perhaps literature’s greatest representation of this idea is Plato’s infamous book The Republic. Rooted in illustrating education’s impact on the nature of man and our perception of reality, Plato’s Allegory of the Cave suggests that one’s discernment of reality’s limitations is bound by what the senses...

Calculus

...change, and since it’s inception in the 17th century, it has changed the world. I also believe it to be the keystone to changing our future. Studies and general common sense show that our world is quickly deteriorating, and although judgements vary, it is no secret we will soon be evicted from Earth. Our future relies in physics, as it is our only foundation for understanding the world outside our world, and Calculus is our foundation for understanding our sole gateway. Physics would be just a game if it weren’t for Calculus, and we need the higher level of physics to comprehend what is outside our atmosphere and galaxy. Once the day approaches where humanity’s existence is futile and we are being shipped off to our new home in some foreign galaxy, Calculus will be our intellectual voucher to save humanity and all of it’s progression since our conception. Yes, I like all, have suffered through its limits and fundamental theorems, but I, unlike all, see the value in the deed. People love to hate it, but what I’ve learned while racing at the highest level, is that you need to embrace the struggle, and use that struggle to achieve something greater than yourself. I’ve lost entire days of my life studying for seemingly pointless tests, struggling to grasp optimization. You need to learn to embrace that pain though, to grovel in happiness, because despite what some desire, my generation will be running the world shortly. I stand firmly behind Leibniz, in the face of formidable......

Math

...The furthest I ever made it in school was Algebra II and I barely passed that. The reason wasn’t that I couldn’t understand math. It was more that I didn’t apply myself to the concepts of it, or the practice and study it took to get there. I was always more interested in other concepts. Concepts that were gathered by free thinkers, philosophers, idealists. Now I knew that a lot of those figures I read about tried their hand in the sciences, physics, and mathematics in their day, but I was more interested in their philosophical views on everyday life. It was not until I started reading on the subject of quantum physics and standard physics that I became interested in math. The fact that the laws of standard physics didn’t apply to quantum physics intrigued me. I thought these were awesome ideas, but since I only took myself so far in math I was limited in my understanding of it. It took time to regret the fact that I didn’t apply myself to math all of those years. I would have gotten much further in the understanding of the physical world today. When, I saw that you could go out of the boundaries of...

Understanding Science

...Understanding Science For many people, science is something to be dreaded – boring math problems and pointless information. Science, however, plays an important part in the world around us. Not only does science rule every part of the human life, from the inner workings of the body to DNA, but it also explains the world that we live in. Even though, many times, science is looked at as an annoying extension of math and, therefore, something to be despised, understanding it can be extremely helpful in understanding our own lives. Science allows us to understand and answer the big questions that cause many people to turn to religion and their beliefs. Science is a way of understanding the world through examination and testing. It can be defined “as the process of observing and questioning the world around us. We also sometimes call the things that we learn through experimentation science” (Red Orbit). As such, science is the process of studying and testing theories to create a hypothesis. It is a very broad subject matter and encompasses many branches, most ending with the –ology suffix, meaning the study of. Biology, for example, is the study of the life where Geology is the study of the earth. People that study biology and geology are scientists because they follow the scientific method, “the most powerful method ever invented by humans to obtain relevant and reliable knowledge about nature. In fact, it is really the only method we have for discovering reliable knowledge......

...comprehend the composition of the most basic cells. The exact issues are the current issues in the field of physical science today, but it’s particularly true in the world of physics. While new technologies exist to measure phenomenon, it is not always safe to do so in the field that deals with radiation, unstable compounds, particles and atoms. As a result, the technology that we have in the field of physics, but across the board in the physical science field of astronomy, chemistry, physics and earth science. Challenges in Measurements Over the years there have been many adventures that allow for direct measurements within the field of physics, there are still many obstacles and challenges to making direct observations. Physics is the study of energy and matter and the interaction between-both of which are impossible to observe with the naked eye. The first major challenge in making direct measurement in physics is the size of the particles being studied. To solve this issue, physicists study these particles indirectly through things like associated radiation, their energy, or the displacement of other atoms. Almost all measurements that have been made on atoms or subatomic particles has been the result of indirect measurement. The second major obstacle to direct measurement in the field of physics is the Heisenberg Uncertainty Principle. This principle states that it is important to measure both velocity and the location of a particle at exactly the same time,......
