That’s physics, stage four-more precise, more specific expressions of the same idea.įlow systems are everywhere.

But I would specify and say that the tendency is toward evolving freely-changing on the go in order to provide greater and greater ease of movement. The Constructal Law says there’s a universal evolutionary tendency toward design in nature, because everything is composed of systems that change and evolve to flow more easily. Your new book is premised on a law of physics that you formulated in 1996.

In your magazine and on your TV channel, we see many animals doing this-extending their reach with tools, with intelligence, with social organization. Therefore all the things that we make-our tools, our homes, our technologies-are natural as well. One thing that came directly from Charles Darwin is that humans are part of nature, along with all the other animate beings. In Latin, nature-physics-means “everything that happens.” Our narrow definition of the discipline is something that’s happened in the past hundred years, thanks to the immense impact of Albert Einstein and atomic physics and relativity at the turn of the century.īut we need to go back farther. Does that mean we can unite all behavior under physics?Ībsolutely. According to your book, physics describes the actions or tendencies of every living thing-and inanimate ones as well. To wrap our heads around this counterintuitive premise, National Geographic recently spoke with Bejan about the physics of life, the universe, and everything. Harking back to the original definition of the discipline-“knowledge of nature” in Greek-he ultimately concludes that “life and evolution are physics.” But his new book, The Physics of Life: The Evolution of Everything, may be the broadest consideration yet. The same principles of physics, he argues, can be applied to all things that move, morph, and flow, from sports and technology to air currents and population growth, migratory patterns and social hierarchy.īejan isn’t the first person to study behavior as physics, or to use physics to describe wider systems. But the iconoclastic energy scientist-a mechanical engineering professor at Duke University and one of the world’s foremost experts on thermodynamics-thinks of pretty much everything else as well. HOW DO ENERGYS EFFECT THE BODY? POSITIVE, NEGITIVE, CHI, ELOPTIC, LIFE FORCE ENERGY.When you think of physics, what comes to mind? Atomic energy? Gravitational waves? Maybe Newtonian equations?Īdrian Bejan thinks of those things too. Some of the claims made by manufacturers of energy drinks - such as "improves performance and increases concentration" - can be misleading.Ĭonsider a better way to boost your energy: Get adequate sleep, But you shouldn't see them as some "natural" energy boost - the boost they give is from caffeine. But too much caffeine can cause adverse side effects, such as nervousness, irritability, increased heart rate and blood pressure, and insomnia.Įnergy drinks are not necessarily bad for your health. Caffeine is a stimulant, which also can temporarily perk you up. Although the various sugars used to sweeten energy drinks can briefly increase energy, consuming large quantities of sugar is likely to cause weight gain. The "boost" typically comes from the large amount of sugar and caffeine these drinks contain. Actually energy drinks may give you a temporary energy boost. People have a mind set that energy drinks really boost them to do work or to relax more. Inside the cell, chemical reactions occur that produce the new forms of energy and yield by-products such as water and waste materials see also adenosine triphosphate.Ī. Molecules of the food substances providing energy pass through the cell wall. The body transforms chemical energy derived from food by the process of metabolism, an activity that takes place in the individual cell. Proteins work to build and restore body tissues. Of these three, carbohydrates most readily provide the kind of energy needed to activate muscles. The human diet comprises three main sources of energy: carbohydrates, proteins, and fats.

Usually there is loss in the form of heat, which escapes or is dissipated unused all energy changes give off a certain amount of heat.Īll activities of the body require energy, and all needs are met by the consumption of food containing energy in chemical form. In these changes some of the energy is “lost” in the sense that it cannot be recaptured and used again. In doing work, the energy is changed from one form to one or more other form(s). Energy assumes several forms it may be thermal (in the form of heat), electrical, mechanical, chemical, radiant, or kinetic. Power that may be translated into motion, overcoming resistance or causing a physical change the ability to do work.
