The 8 Best Physics Textbooks
Are Physics Textbooks Only For Students?
Physics is the study of forces that govern much of the known universe. Concepts of physics directly influence every aspect of life, so it is no wonder the number of people choosing to study the topic is on the rise. Physics textbooks provide an easy way for students of all ages to learn about these concepts.
Contrary to popular belief, physics textbooks are not simply for academics. While many are written to cater to institutions of higher learning, a self-learner stands to benefit from them, as well. Physics textbooks tend to be broken down into succinct and easy-to-follow chapters. The study of physics textbooks also tends to take place in order, meaning that they will not delve into the mind-boggling realm of spinning tops before they explain Newton's Laws.
Any prerequisites for understanding concepts are generally covered in the first few chapters of a textbook, and can help bring any learner up to speed with some of the most basic concepts of physics. It is also important for the reader to have a strong grasp over basic algebra and trigonometry, as well as concepts like the Pythagorean theorem.
Textbooks are also made to be read. While it can seem like an obvious notion, the technical literature put out by the physics community is difficult to follow by most standards. Textbook manufacturers take it upon themselves to digest this information and rewrite it in ways that make the concepts accessible to all who read them.
What Types Of Topics Do Physics Textbooks Cover?
The ultimate goal of physics is to better understand physical reality. To do this, physicists have formulated a series of fundamental laws and theories used to describe how forces in reality function. From the first time a physics textbook is opened, some basic principles will need to be covered and understood.
While physics is evolving every day, the understanding we have of the basic theories of physics came from one man in the 17th century, Sir Isaac Newton. Newton's first law of motion states that an object at rest will remain at rest unless acted on by an outside force. Likewise an object in motion remains in motion unless acted on by an outside force. His second law of motion states that acceleration occurs when a force acts upon a mass. The greater the mass of the object, the more force it will require to move. Newton's third law famously states that for every action there is an equal and opposite reaction.
Newton also developed a law of gravity, which explained the attractive force between a pair of masses. This was an incomplete law, however. A more comprehensive understanding of gravitational forces came with Einstein's most notable equation, E=mc². This theory of relativity shows that the increased mass of a body comes from the kinetic energy of that body, divided by the speed of light squared. This raised the idea that mass and energy are the same physical entity, and changed the field of physics forever. These make up some of the most basic concepts that every physics textbook will touch on.
Noteworthy Fields Of Physics
The public interest about the topic of physics has piqued in the modern era. While physics as a whole is the study of the nature and properties of matter and energy, there are a vast number of different fields covering various aspects of physics.
Particle physics is one such field that has gained popularity recently. This is largely due to a number of new discoveries being made, such as the Higgs-boson particle. In short, the Higgs-boson particle is responsible for giving the universe its mass. The Higgs field was the last missing piece in the Standard Model of particle physics. The discovery of the Higgs-boson particle marked a huge milestone in the human understanding of nature, and allows physics to move towards new discoveries with ease.
Quantum physics is another interesting area that deals with the fundamental theory of nature on the smallest scale. Fro example, one principle of quantum physics is that everything in the universe is made up of particles, while simultaneously being made up of waves. For instance, a photon is considered to be a particle of light. In reality, it is not a particle alone, but an excitement occurring in a quantum field of energy. It is easy to isolate small particles like photons or electrons in conversation, but in their natural state, they exist in the inseparable particle-wave state.
Another fascinating idea stemming from quantum physics is the idea of quantum entanglement. In quantum physics, any particles which are entangled remain connected even after they separate. Actions performed on one of these particles will affect the other entangled particle. Two entangled particles may have miles put between them, but if one begins an action, the other begins a similar action near-instantaneously. While Schrodinger was the first to use the term entanglement, Albert Einstein famously called it spooky action at a distance.
