Motorvationally Speaking: "Energizing Thoughts"

In physics, energy (from the Greek - energos) is a physical quantity describing the amount of work that can be performed by a force, an attribute of objects and systems subject to a conservation law.

In New Brunswick, Leah helps uphold that law.

She could tell you for example, the many different forms of energy; kinetic, potential, thermal, gravitational, sound, light, elastic, and electromagnetic can be transformed into another form, but the total energy always remains the same.

Leah is helping all New Brunswickers appreciate a principle about the conservation of energy, first postulated in the early 19th century. According to Noether's theorem, conservation of energy is a consequence of the fact that the laws of physics do not change over time. And Leah is someone who actually puts that principle into practice on most Saturday mornings when you find her shopping for produce at her local farmers market.

Today on TSB, we share some energizing thoughts and convenient truths with Leah Anstis of the Conservation Council of New Brunswick.

"Motorvationally Speaking", on CHCD TV, is a weekly, internet-based show focused on people who embrace the power of positive thinking. The guests may not always be famous, but they are always enlightening, and each one of them has an interesting story to tell. Your comments and suggestions are always welcome as we aim to inspire, educate and motorvate.

"There is a fact, or if you wish, a law, governing natural phenomena that are known to date. There is no known exception to this law; it is exact, so far we know. The law is called conservation of energy; it states that there is a certain quantity, which we call energy, that does not change in manifold changes which nature undergoes. That is a most abstract idea, because it is a mathematical principle; it says that there is a numerical quantity, which does not change when something happens. It is not a description of a mechanism, or anything concrete; it is just a strange fact that we can calculate some number, and when we finish watching nature go through her tricks and calculate the number again, it is the same"
