17th Dimension

Imagination is more primary than knowledge. Knowledge is limited. Imagination encompasses the world. -Albert Einstein. Speaking of physics can cause a variety of responses. Not gossip again if physics is one of the "ghost" that dreaded by many students, both in the secondary level, general, and even in college.

Some people memorize physics formulas like a history book without realizing its meaning.
There is also a resigned because he considered physics belongs only to people who are serious, intelligent, crazy math, and in general "less slang."

In fact, not a few who think that making life physics as a career is the wrong choice because "the entry of" easy but "out" difficult. In other words, a student of physics is not difficult but lulusnya half dead and it works at most be a teacher or if lucky enough to be a lecturer.

Some admire physics students because reading the news about the success of the Olympic team of physics or reading a book about the lives of great scientists. Unfortunately, many also admired not only to appreciate or learn physics. Often people who master the physics are considered as the "cool" and "weird" for wanting to learn something difficult, but if so it could be wealthy businessman.

Such perceptions lead to the general public tend to be fond of other sciences such as metaphysics. While other countries try to sensitize the people for not "gatek" aka stammering science and technology of our country through some mass media seems to work hard to convince people not to "gagib" or stutter supernatural.

In fact, the submission of this information using the application of physics and electronics. In short, find someone who likes physics is like looking for a pin in a haystack.

Lots of students or students who are patiently awaiting delivery of physics formulas on the blackboard, then working on the problems of physics. From experience, the problems were solved by means of "mutual assistance" because only a few people are able or willing to do it. The success of teaching does not seldom based on the ability to do the final exam questions, rather than on mastery of the physical meaning of the formula.

For example, almost everyone in the class know Newton's second law, F = ma, but probably never imagined that such formulas can tell you why fat people would rather play tug of war than 100m.

Then, who is not familiar with Einstein's famous equation E = mc2? Unfortunately, very few people know that the mass of a book containing the basic physics of energy that can bring a spacecraft to the moon!

One cause of negative perceptions about physics is that science is often taught without appreciation so that was annoying. In fact, the physics we can know many things. A student who began studying the science does not need all the way to visit the laboratory to see the phenomena of physics.

Whenever and wherever he can imagine (menghayal) on the surrounding environment.
The beauty of the flower color is visible to the eye, comfortable-sounding music in the ears, enchanting waterfalls, the cool air flow, are few examples of the physics of everyday phenomena.

The explanation that every color has a wavelength that is different, and that objects absorb and radiate certain wavelengths, so get to our eyes, can be read in a physics book. But often people do not care about the explanation for not imagining that he forgot the beauty of nature and have no curiosity.

Imagination is born from an environment that supports a person for thinking about various phenomena around it. If the local community or family at home does not appreciate the freedom of thought, the power of imagination is difficult to develop. Almost all famous physicists are people who like imaginative thinker and is often described as "radical" because it was considered strange by the environment are often dogmatic.

Einstein is a popular example of people who like their imagination and develop it. He imagines what if he can move with the speed of light. Thinking this odd result in the theory of special relativity, which until now still used. The same is done by Newton. If only she did not like daydreaming under the apple tree may be the law of universal gravitation was not discovered until decades later.

Through imagination, consciousness to observe natural phenomena and reading physics books would present itself. For example, water molecules (H2O) consists of two hydrogen atoms and an oxygen atom. We certainly can not see the water molecules with the naked eye. However, we can imagine that the molecules are very small, so do not appear.

Accordingly, the number of molecules that make up a body to be very much. Through the imagination we are thrilled to learn that a mole of molecules of water (which weighs about 18 grams) contains about 6 x 1023 molecules. So, one tablespoon of water was composed of approximately 1022 molecules. The amount is very large. If the entire population of Indonesia was given the task to calculate the different molecules one by one every 5 seconds then it takes billions of years!

Physicists do not make the formulas to be memorized or written on the palm. Formulas are made to understand natural phenomena in a concise, beautiful, universal, and useful for solving problems related to such phenomena. Indeed, physics is not possible apart from mathematics.
Without the mathematical definition, physics is very difficult to develop and dimanfanfaatkan as technology.

However, to learn the basics of physics one does not need to be "crazy" mathematics or become serious and fear can not be a boyfriend because of "lack of slang." Learning physics is not easy, but with escape from dogmatic thinking and desire to think freely, imagination will appear and can be a fun adventure for anyone.

River Gorge in South Africa matchless beauty store. Lots of physical phenomena that make the scene above is breathtaking: Legal reflection and refraction produce a picture 'of the mountain upside down' is seen above the river surface. Polarization of sunlight by molecules in the air to give blue scenery is very harmonious with the colors green and brown.

Wind due to the difference in air pressure move the tree foliage in terirama. Looks an animal consumes food and drink to sustain life, a process of reducing the entropy (disorder) by adding energy in the animal. Physics Is not it beautiful?
