Physics 101 is the first course in the Introduction to Physics sequence. In general, the quest of physics is to develop descriptions of the natural world that correspond closely to actual observations. Given this definition, the story behind everything in the universe, from rocks falling to stars shining, is one of physics. In principle, the events of the natural world represent no more than the interactions of the elementary particles that comprise the material universe. In practice, however, it turns out to be more complicated than that. As the system under study becomes more and more complex, it becomes less and less clear how the basic laws of physics account for the observations. Other branches of science, such as chemistry or biology, are needed.  In principle, biology is based on the laws of chemistry, and chemistry is based on the laws of physics, but our ability to understand something as complex as life in terms of the laws of physics is well beyond our present knowledge. Physics is, however, the…

The physics of the universe appears to be dominated by the effects of four fundamental forces: gravity, electromagnetism, weak nuclear forces, and strong nuclear forces.  These forces control how matter, energy, space, and time interact to produce our physical world.  All other forces, such as the force you exert in standing up, are ultimately derived from these fundamental forces. We have direct daily experience with two of these forces: gravity and electromagnetism.  Consider, for example, the everyday sight of a person sitting on a chair.  The force holding the person on the chair is gravitational, and that gravitational force balances with material forces that “push up” to keep the individual in place.  These forces are the direct result of electromagnetic forces on the nanoscale.  On a larger stage, gravity holds the celestial bodies in their orbits, while we see the universe by the electromagnetic radiation (light, for example) with which it is filled.  The electromagnetic force also makes…

The free online course Physical Fitness - Fitness Tips and Workout Routines has been designed to teach you how to improve your physical health and well-being. The course will introduce you to the theoretical apsects of physical fitness and provide you with practical workouts that can help you develop and maintain it. Obesity is becoming a global epidemic in developed countries across the world and is associated with many chronic diseases such as diabetes, heart disease and some forms of cancer. Research has consistently proven that maintaining a high level of physical activity and fitness can have significant benefits on many aspects of your life including your physical health and mental health. The course begins by introducing you to the basics of exercise physiology – the branch of science which studies how the body responds and adapts to physical exercise. Firstly, you will be introduced to definitions and terminology that are central to exercise physiology. This will help you obtain a strong grounding in the subject and benefit your learning throughout the course. You will then study the cardiovascular system and the skeletal muscular system. You will learn how the cardiovascular system functions and how the heart supplies oxygen-rich blood to the active skeletal muscles during exercise. Finally, you will examine various activities and workouts that have been shown to increase cardiovascular fitness. This course will be of great interest to professionals who work in the health and fitness industry and to anyone who wants to learn more about improving their physical fitness. <br />

The free online course Physical Fitness - How to Avoid Injuries and Train Safely is designed to show you how to train safely in challenging environments, how to prevent and treat a range of injuries and what effects performance enhancing substances can have on your health. The course begins by focusing on three specific environments in which it is difficult to safely train: extreme heat, extreme cold and high altitude. You will learn the necessary precautions that must be taken in order to ensure that you stay safe in each environment. First you will learn how the body adapts to protect itself in each environment, next you will study the external factors that can make it difficult for your body to adapt to each environment and to conclude you will study a range of conditions that can be acquired from failing to take the necessary precautions to remain safe in each environment. The course then continues to examine something which individuals who regularly engage in physical training will experience, namely, injuries. You will learn how to identify common indicators of injury such as swelling, inflammation and reduced range of motion. Next, you will study the most common injuries that are experienced by those who engage in regular physical activity. Finally, you will learn how to prevent and treat a range of injuries including fractures, sprains and shin splints. The course concludes by examining the effects performance enhancing substances such as anabolic steroids can have on your body. You will study both the positive and negative effects of anabolic steroids and examine the legal implications of taking them. You will also examine a range of other performance enhancing substances including human growth hormone, erythropoietin and ephedrine. You will learn about the effects that they can have on your overall performance and long-term health. This course will be of great interest to anyone who wishes to gain a greater insight into the necessary steps that must be taken to remain safe while training. The course will also be of interest to professionals who work in the health and fitness industry or individuals who may be interested in pursuing a career in the health and fitness.<br />

For all of the bodies attached to the many great minds that walk the Institute's halls, in the work that goes on at MIT the body is present as an object of study, but is all but unrecognized as an important dimension of our intelligence and experience. Yet the body is the basis of our experience in the world; it is the very foundation on which cognitive intelligence is built. Using the MIT gymnastics gym as our laboratory, the Physical Intelligence activity will take an innovative, hands-on approach to explore the kinesthetic intelligence of the body as applicable to a wide range of disciplines. Via exercises, activities, readings and discussions designed to excavate our physical experience, we will not only develop balance, agility, flexibility and strength, but a deep appreciation for the inherent unity of mind and body that suggests physical intelligence as a powerful complement to cognitive intelligence.
