His laws changed all of physics and astronomy. His laws made it possible to calculate the mass of the sun and planets. The way it's done is immensely beautiful. If you know the orbital period of any planet, say, Jupiter or the Earth and you know its distance to the Sun; you can calculate the mass of the Sun. Doesn't this sound like magic? We can carry this one step further - if you know the orbital period of one of Jupiter's bright moons, discovered by Galileo in 1609, and you know the distance between Jupiter and that moon, you can calculate the mass of Jupiter. Therefore, if you know the orbital period of the moon around the Earth (it's 27.32 days), and you know the mean distance between the Earth and the moon (it's about 200,039 miles), then you can calculate to a high degree of accuracy the mass of the Earth. … But Newton's laws reach far beyond our solar system. They dictate and explain the motion of stars, binary stars, star clusters, galaxies and even clusters of galaxies. And Newton's laws deserve credit for the 20th century discovery of what we call dark matter. His laws are beautiful. Breathtakingly simple and incredibly powerful at the same time. They explain so much and the range of phenomena they clarify is mind boggling. By bringing together the physics of motion, of interaction between objects and of planetary movements, Newton brought a new kind of order to astronomical measurements, showing how, what had been a jumble of confused observations made through the centuries were all interconnected. ↗
Until fairly recently, every family had a cornucopia of favorite home remedies--plants and household items that could be prepared to treat minor medical emergencies, or to prevent a common ailment becoming something much more serious. Most households had someone with a little understanding of home cures, and when knowledge fell short, or more serious illness took hold, the family physician or village healer would be called in for a consultation, and a treatment would be agreed upon. In those days we took personal responsibility for our health--we took steps to prevent illness and were more aware of our bodies and of changes in them. And when illness struck, we frequently had the personal means to remedy it. More often than not, the treatment could be found in the garden or the larder. In the middle of the twentieth century we began to change our outlook. The advent of modern medicine, together with its many miracles, also led to a much greater dependency on our physicians and to an increasingly stretched healthcare system. The growth of the pharmaceutical industry has meant that there are indeed "cures" for most symptoms, and we have become accustomed to putting our health in the hands of someone else, and to purchasing products that make us feel good. Somewhere along the line we began to believe that technology was in some way superior to what was natural, and so we willingly gave up control of even minor health problems. ↗

We have learnt that the exploration of the external world by the methods of physical science leads not to a concrete reality but to a shadow world of symbols, beneath which those methods are unadapted for penetrating. Feeling that there must be more behind, we return to our starting point in human consciousness - the one centre where more might become known. There we find other stirrings, other revelations than those conditioned by the world of symbols... Physics most strongly insists that its methods do not penetrate behind the symbolism. Surely then that mental and spiritual nature of ourselves, known in our minds by an intimate contact transcending the methods of physics, supplies just that... which science is admittedly unable to give. ↗
We look for the Secret - the Philosopher's Stone, the Elixir of the Wise, Supreme Enlightenment, 'God' or whatever...and all the time it is carrying us about...It is the human nervous system itself. ↗
