A GPS receiver compares time signal transmissions from four or more satellites to calculate the precise time and its current position (latitude, longitude, elevation), using trilateration. The receiver computes the distance to each of the four satellites from the difference between local time and the time the satellite signals were sent (this distance is called a pseudorange). It then decodes the satelli ...

When it was first deployed, GPS included a feature called Selective Availability (or SA) that introduced intentional errors of up to a hundred meters into the publicly available navigation signals, making it difficult to use for guiding long range missiles to precise targets. Additional accuracy was available in the signal, but in an encrypted form that was only available to the United St ...

Visualization is easy to use. Like all the other tools of creation, we use visualization every day to create our experience of reality. Daydreaming, fantasizing, mental rehearsals, and imagination are all examples of visualization. We have all daydreamed about an upcoming vacation or a visit with a favorite friend. Many of us have fantasized about winning the lottery or getting a better job.

One of the often overlooked keys to making visualization and affirmations work is the feelings involved. Imagining success without mixing in a whole lot of positive feeling is nothing more than a mental exercise. But fuel your visualization and affirmations with faith, gratitude, passion, or excitement and suddenly you have a powerful life changing tool. That tool is simply the imagination.

A reader writes: "It seems like I only get results from visualizing when I say what I want in an angry or forceful way. If I try to use positive emotions like gratitude or happiness, it just doesn't work.

I've heard that powerful emotions make the process go faster. Are we such slaves to our old thoughts that there's no other way to tunnel through to our inner mind?"

Outstanding question!

Studies have shown that more than 90% of self-talk is negative. In other words, all day long, you fill your mind, consciously or not, with negative thoughts and unproductive feelings. You therefore get a corresponding life. The law of attraction doesn't know (and doesn't care) if this is a good or bad thought. It attracts whatever you're thinking about. The solution to a more successful life is simply asking yourself: "So, what do I really want?" Take some time to define your ideal lifestyle, in every aspect of your life: family, business, financial freedom... And now that you have defined these goals, use techniques like affirmations or visualization to literally flood your mind with positive, motivating thoughts and feelings.

Each of us possesses the ultimate tool for creating success and attracting the things in life we truly desire. What is the secret? Our positive thoughts. Oh, I hear the skepticism, but it is entirely true! Our lives are like the proverbial blank canvas and we hold the paintbrush.

In the infamous words of Napoleon Hill, "Anything your mind can conceive and believe, it can achieve." Meaning, it is up to us to visualize and manifest the things that we want in life, including money and prosperity. Doesn't it sound easy? Actually it is, but in order for it to work we need to silence the negative self talk voices that tell us that our thoughts are crazy or unachievable.

The best form of visualisation is when you try and affirm your oneness with the Divine Spirit. Sit, relaxed and comfortable, in a chair with your spine straight, or on a mattress in the meditative/cross-legged posture. Focus your gaze on the area of the third eye in between your eyebrows.

This in yogic terms is the seat of concentration and will power. Fill your heart and your mind with the joy of God or any other happy feeling that you are able to relate with. Know yourself to be a being of light. Forget the heaviness of the body. See yourself surrounded by this ball of light. It is immersing you in its warmth and permeates you into the space around. This light is the presence and consciousness of God.

Visualisation is the process of focusing your concentration on an image of what you want and seeing it as already having manifested. It is a ritual of going in into the inner recesses of your mind, and with the power of the subconscious mind, causing the manifestation of the desired object, instance or circumstance.

Visualisation resembles our familiar habits of fantasies, daydreams, and imaginations but entwines a certain discipline into them. Visualisation is not imagination, though the dividing line is very subtle. Imagination is an outward projection of the mind and has its foundation in desires and emotions.

For the achievers, the need to dream beyond what is possible, passion for the job, enthusiasm and sense of purpose are the prime tasks. The mental attitude to set clear goals, patience and perseverance even when the results are not visible, and the ability to take failure in one's stride sets these men and women apart. Positive thinking is critical.

We are what we choose to be. Man has access to all the gifts given by Existence. Yet life on earth for many is one of want and deprivation. There are people living below relative poverty lines, and there are those who are overwhelmed by their excesses in wealth. Why these differences? Is it that God is partial and kind to one at the cost of another?

No! Relative differences arise because one believes that the abundance of the earth is for him to reach out and access, while the poverty-torn person unconsciously and continuously re-affirms his / her poverty-consciousness.

Change all thoughts to empowering ones. Ask not "Why me?" Ask, "What can I do to reach my goals?" Change any mindset of "I can't" to a mindset of "I can." Just as when you climbed the high diving board as a child, gave a first speech in college, got married, or decided to be a parent, you will find the strength to face any future challenges.

Change any overly independent thoughts such as "I'll handle this alone" to "I have many sources of help, if I simply ask." Shift any catastrophising thoughts such as "This is the worst thing that could happen to me" to "I'm sure I'll survive this one."

An affirmation is a statement of truth which one aspires to absorb into his life. It has been said that we are what we eat. It would be truer to say, "We are what we think." For our minds express, and also influence, the reality of what we are far more than our bodies do. Our thoughts even influence, to a great extent, our physical health.

Words, which are crystallized thoughts, have immeasurable power, especially when we speak them with concentration. The mere thought of fatigue is enough to sap our energy. To strengthen that thought by the words, "I'm exhausted," gives definition, and therefore added power, to the thought itself.

Men of great success have been men of great concentration. Success does not come from outside. It is right within your brain. When a brilliant thought /idea strikes you, it needs to be nurtured and reared with patience, will, focus, and determined action. Only then will the tiny seed of an idea truly flower into a vibrant plant. The entire basis of the flowering is the mind and its powers.

Concentration involves a honing in of the attention so that one's entire field of attention is thrown into whatever it is that one is doing. Concentration entails a focusing of energy-the energy that influences all our actions in life.

Ralph Emerson, the 20th century American philosopher, described man as the "ever-losing winner". We tend to measure God's blessings on the basis of how many of our prayers have been answered - we compare what we sought with what we got. We do not often get what we prayed for. Then we accuse God of being unkind. Subsequently, we discover later that whatever happened was in fact for the good. The 'bad' event turns out to be a blessing in disguise.

In time of spiritual need and strength I silently utter prayers that come to my mind, often from various faiths. I repeat them to still a restless, turbulent mind. Sincerity of action is important. It is alarming, disturbing, terrifying and heartbreaking to witness religious strife and the atrocities that are taking place in the name of religion.

We don't have to comprehend each and every ritual. It is more important to be a good human being - this is what God expects of each one of us irrespective of our religion.

Are miracles just mumbo-jumbo, products of a willing suspension of disbelief? Or are they 'real', as the faithful would have us believe? A miracle, essentially, implies a hiatus in natural causality, brought about by divine or supernatural intervention.
