Do you know?
Matter is everything, everything means everything. The air you breathe, the t-shirt you wear, the smartphone you have. Everything is made of the matter including your body.
Physics is the study of your world and the world and universe around you. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Over the last two millennia, physics was a part of natural philosophy along with chemistry, certain branches of mathematics, and biology, but during the scientific revolution in the 17th century, the natural sciences emerged as unique research programs in their own right.
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 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, and nuclear weapons; advances in thermodynamics led to the development of industrialization; and advances in mechanics inspired the development of calculus.
Physics is a way of thinking. It helps you to develop analytical skills that you can apply to many problems in life. The ability to analyze problems is a learned skill that requires practice and effort. The more you work at problem solving, the easier it will become. The physics problems in this book will provide you with extensive practice in analyzing physical situations and solving problems.
