Physics (Greek physis - f?s??) is the science of matter[1] and its motion. [2] It is the science that seeks to understand very basic concepts such as force, energy, mass, and charge. More completely, it is the general analysis of nature, conducted in order to understand how the world around us and, more broadly, the universe, behaves. [3][4] Note that the term ' universe' is defined as everything that physically exists the entirety of space and time, all forms of matter, energy and momentum, and the physical laws and constants that govern them. However, the term ' universe' may also be used in slightly different contextual senses, denoting concepts such as the cosmos, the world, and nature. In one form or another, physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy.[5] Over the last two millennia, physics had been considered synonymous with philosophy, chemistry, and certain branches of mathematics and biology, but during the Scientific Revolution in the 16th century, it emerged to become a unique modern science in its own right.[6] However, in some subject areas such as in mathematical physics and quantum chemistry, the boundaries and the borderlines of physics remain difficult to distinguish. Physics is both significant and influential, in part because advances in its understanding have often translated into new technologies, but also because new ideas in physics often resonate with the other sciences, mathematics and philosophy. For example, advances in the understanding of electromagnetism led directly to the development of new products which have dramatically transformed modern-day society (e.g., television, computers, and domestic appliances); advances in thermodynamics led to the development of motorized transport; and advances in mechanics inspired the development of the calculus, quantum chemistry, and the use of instruments like the electron microscope in microbiology. Today, physics is both a broad and very deep subject that, in practical/fundamental terms, can be split into several subfields. It can also be divided into two conceptually different branches Theoretical physics and experimental physics. The former deals with the inquiry and foundation of new theories while the latter deals with the experimental testing of these new, or existing, theories. Even though significant progress and important discoveries have been made in the field of physics during the last four centuries, many significant questions about nature and the universe still remain unanswered. In many areas of physics, it is still a continuing effort to try to gain a clearer understanding to the unknown and the outskirts of physics.

1. Awakening Psychic Abilities
November 18, 2008
Do you think you may be developing your own psychic abilities? We all have them to a lesser or greater degree, because the study of quantum physics has shown that we are all connected in the universe. An interesting observation was made in the film "What the Bleep Do We Know" - that the very thing (our minds) that perceives the tangible world around us, is itself intangible. The meaning behind this lies in the way our thinking conscious mind operates. It is not the "brain flesh" that does the thinking, but the hologram inside (and around) our skull, that the brain produces. Understanding th... (read more)

2. Skydiving: All About Skydiving Weights
November 08, 2008
If you want to go skydiving, having the proper equipment is a must. Although there are some equipment that are considered to be staples or standards when diving, there are also those that can be add-ons depending on your body and the type of jump you’ll be doing. One of these extra equipments is called weights.
What Are Weights For?
Physics has a lot to do with skydiving, which is why your weight can affect how fast or slow gravity can pull you. If it’s the case that you’re reasonably light, you would sometimes have to fly at your range’s edge in a rather extreme body position that i... (read more)

3. Guitars and the Damaging Effects of Temperature & Humidity Extremes.
November 07, 2008
An acoustic guitar is a remarkable piece of engineering. It is at the same time quite fragile, yet also remarkably strong. The entire structure is built around the need to produce a good sound while resisting the force of approx 180 pounds (800N) of tension exerted from the strings which are trying to pull the head of the guitar around toward the body. When this tension succeeds physics has won the battle and the guitar then ranges from difficult through to impossible to play. This can take a long time to occur, sometimes years, and we only start to notice when it’s getting too late to save th... (read more)

4. vastu yantra
November 06, 2008
Often we can hear about the term ‘Vastu’ while starting any kind new project. What can be studied from the phrase ‘Vastu’? It signifies that Vastu is a perfect perceptive of geography, direction, topography, physics and environment. The world is moving to an advanced stage with modernization and tends to leave back the Vedas, which causes us to face many problems in life. Most of the people use dynamic planning and unstructured architectural procedures leading them to face basic problems in the recent days. i.e Dissonance. In short, it can be said that Vastu connects men and nature. Basically,... (read more)

9. The Physics Of Weight Lifting. Part 5, Power.
October 24, 2008
In our final installment of this series we'll look at the formula for power and how to use it to make training more productive. The formula for power is: Force X Distance -:- Time. And is measured in foot-pounds/second.
In the last issue we talked about work and how to calculate your workload for each workout, the first part of the formula for power is the same (Force X Distance), now we add the factor of time.
Now, for the purposes of muscle building we don't mean increasing lifting speed, this just allows momentum to do the work and not the muscles. All exercises should be prefo... (read more)

10. The Physics of Weight Lifting. Part 4, Work.
October 24, 2008
In part 4 of this series we'll look at the formula for work and how we can use it to monitor our training. The formula for work is: Force X Distance.
When we workout we use a certain amount of muscular force to lift a weight across a certain distance, the work done is measured in Foot/Pounds. If we kept track of the work we do each workout it will tell us much about our progress and also how we should proceed with our training. You can measure the work done each workout in the following way:
1. Take an empty bar and do the full range motion for each exercise you are currently doing i... (read more)

11. The Physics Of Weight Lifting. Part 3, Mechanical Advantage.
October 24, 2008
Here in the third part of this series we will examine mechanical advantage and how this effects weight training and how it can be used to our advantage to get better/faster results. Mechanical Advantage - is the ratio of the force exerted by a machine to the force applied to a machine.
Our muscles contract to exert force and our skeletal structures (made up of simple machines - hinges, ball and sockets, etc..) transfer that force into motion. But the force exerted by our muscles (input) is not equal to the force we can use to move our bodies or lift other objects (output). let's look at ... (read more)

12. The Physics of Weight Lifting. Part 2, Friction.
October 24, 2008
In part 2 of this series we'll look at friction and how it can affect our training. Friction is defined as - (1) A rubbing of one object or substance against another. (2) The resistance to motion of moving surfaces that touch.
When working with machines friction can become a problem, you have the situation of weight on the machine plus friction making it feel much heavier than the weight stack says it is. This can wreck your progression, let's say you're going along on lat pulldowns, last workout you made over 10 reps, you add 5 lbs and start to pull and nothing happens, a big yank gets t...

13. The Physics of Weight Lifting. Part 1, Gravity
October 24, 2008
This is the first of a series of articles that will look to the science of physics to help us make our training more effective. In this article we will look at the simple law of gravity and how this effects lifting weights.
Gravity is defined as - The natural force that causes objects to be pulled towards the center of the earth, it causes objects to have weight.
Because the earth is round, no matter where you are on it the center is always straight down. Thus, in order to have continuous tension on our muscles while training we must make sure the actual resistance we use travels a p... (read more)

October 21, 2008
How Quantum Physics, Your Brain, and Your Heart Manifest Your Vision and Goals
For many years I heard that you had to start with a vision for your business or your life if you really wanted to succeed, but no one could explain to me why it was needed or how it worked from a practical or scientific standpoint.
When I was young and naïve, I was skeptical and wanted empirical evidence showing me why I should invest my thoughts and time into really thinking about a vision for my life and business, and why getting absolutely clear by writing it down was imperative to my achieving success.... (read more)

18. Karma
October 13, 2008
Karma is thought to be very much like the Biblical "...an eye for an eye, a tooth for a tooth...", or the more poignant, "...sow what you reap..." In physics there is a concept that supports the view that "every action has an opposite and equal reaction."
Karma is thought to be the process by which energy returns to the individual in the same or similar form expressed by that individual. If the individual expresses violent energy, for example, that violent energy will return to that individual perhaps in this life, perhaps in the next.
The Beatles song, "Instant Karma" relates it thi... (read more)

20. GOLF SCHOOL AND THE OVERLOOKED FUNDAMENTAL
September 19, 2008
The golf swing is first and foremost a motion. No matter how well accomplished someone may be at the static positions of the golf swing, a repeating motion is the cohesion that ties them all together. Since it is, it must adhere to some simple laws of physics…namely the law of inertia and centrifugal force. The law of inertia states that once something is in motion is will stay on its path and in its plane of movement unless an outside force acts upon it. Centrifugal force is simply the outward tug on an object that is rotating around a central point or axis. Take full advantage of these two f... (read more)

23. Processes Involved In Blavatsky's Writings and its effects
September 09, 2008
Helena Petrovna Blavatsky (HPB) demonstrated the Siddhis (psychic-spiritual faculties) of clairvoyance, clairaudience, and the powers of projection, precipitation and being en rapport. These were all used in her writings on Occult science and Meta Physics which may be categorized into seven kinds of processes. We outline them below but it is emphasized that none of the above processes are miracles or supernatural. All fall within natural law, once the operator has developed the faculties to use them. It is obvious that HPB’s writings as just enumerated are proof of this; her literary works wit... (read more)
