5 Learning Styles to Improve Your Study

Some people may feel that learning is a boring stuff. Especially if the subject seems difficult for them to be learned. Despair will eventually lead them to a lazy feeling to learn. Learning is very important, what we learn will determine what will we do in our lives later. To make the learning process easier, We need a kind of learning style or we might call a learning habit. Here are some learning styles to make your learning easier.

1. Study Each day
Psychologists have found that regular practice helps fix a habit. It is easier to form good study habits by studying an hour every day than by studying several hours one or two days each week. To learn something well then we must practice regularly.

2. Study at a regular time each day
Choose a time of day to be used as your study period. Choose a time that would have the least interference. Do not use that time to other activities and concentrate on learning, after all, we only need one hour to study. 

3. Study in a quite place
Psychologist have found that it is generally easier for people to study in a quite place like in a library. People can pay attention more easily to what they are doing.

4. Study with study tools in your hand
Once you give attention to a problem, it is best to keep at it until you finish. So prepare your tools and do not let your concentration distracted because you are looking for tools. In some experiences a tool can also help us in memorizing words or sentences, for example, we want to memorize the word "style" and we use our pen as a substitute for the word, when we see the pen we will remember the word "style".

5. Plan what you will study first
Not everyone finds every subject easy. Psychologists have found that it would be best to study the more difficult subject first because you would be studying it when you are physically fresh.

The Invention of Telephone

When you're learning about something new, it's easy to feel overwhelmed by the sheer amount of relevant information available. This informative article should help you focus on the central points. This article explains a few things about telephone, sound waves, electromagnet waves, transmitter, receiver and if you're interested, then this is worth reading, because you can never tell what you don't know.

The Invention

Having found that a message can be sent through an electromagnetic waves,  some scientists wondered whether  a sound  message  can also be sent through a wire. A scientist named Alexander Graham Bell finally managed to create a tool that can deliver sound messages. The tool that we've known as the Telephone. There's no need to write about how Bell invented the telephone because there has been so many articles about it. Let's focus on the telephone itself.

How does a telephone work?
Telephone has two important components to send and to receive messages. To send a sound message requires a Transmitter to change the sound into a varying electric currents. To receive sounds needed a tool called Receiver that converts varying electric currents, which transmitter has sent, into sound.

In the previous article about Echo, it has been explained that when we make a sound then our vocal chord will vibrate and release sound waves. If the sound waves are received by our ears then we will be able to hear the sound. In the telephone, our sound waves are changed into varying electric currents. When we speak, our sound waves strike a disk of thin metal in the telephone transmitter. Our sound waves make this disk vibrate and change this vibrate into pattern of electric currents. This electric currents have the same pattern as the vibrations of the disk and the vibrations of the disk has the same pattern as our sound chord vibrations / our sound waves. The electric current travels along a wire and changed back into sound by the receiver. But how?

The receiver has two main parts : an electromagnet and a thin disk of iron. when electricity passes through the electromagnet, the electromagnet attracts the iron disk. When the current stops, the disk will spring back. Varying of electric current will make the disk move back and forth or vibrate. Because the electric current has the same pattern with our sound waves so the disk will vibrate in the same pattern. As the disk vibrates, the disk will make sound waves with that pattern. Finally, our ears will catch that sound waves and translate it into sounds. That is how we can hear the sound through a telephone.

Hopefully this articles above has contributed to your understanding about telephone and how it works.  So never stop reading, never stop learning, and never stop sharing with others.

Making Our Own Telegraph

This time I wanted to share the knowledge about how to make a telegraph by simple and use it to send a message. I read in a book of science, to be honest I myself have never tried to built  it, but I might try sharing here. Hopefully useful.

The first one we need:
- 3-inch bolt
- 3-inch nail
- Iron hinge
- Metal strips
- Bell wire
- Screws
- Rubber band
- Batteries 1.5 v
- Woods as shown in the picture

First make a telegraph sounder and key, assemble materials as shown in the picture below. Use a tin cans to make the metal strip for the key.

When you turn on the current by pressing down the key, the hinge should go up and touch the bolt with click sounds. Adjust the height of the electromagnet, if necessary, by turning the nut.
When the current is off, the hinge should drop back on the nail with another click. If the hinge stays up, adjust the pull of the rubber band.
This picture below shows how two sets telegraph Should Be connected. Use the International Morse Code  to send your message. Happy experimenting ....

Telegraph : First Wired Long Distance Communications Tool

This article will discuss about the Telegraph and the work of a telegraph. Who would've never heard the word 'Telegraph', yes it is a tool for a long-distance communication that first created in the world and became a breakthrough for communication tools that we use today. First prototype of the telegraph tested and introduced by Carl Gauss and Wilhelm Weber in the 1830s, but this technology still could not be launched until Samuel Morse perfected it at the end of 1830. It did not take long to make the cities and countries were linked by telegraph wires. The job of a telegraphers looked very glamorous and exciting for young men at that time, one of which was famous named Tom Edison.

Then How a telegraph can send message?
Telegraph is designed to transmit electricity and turn it into electromagnet. There are three parts in the telegraph instrument.
- a key, to send the message
- a sounder, to receive the message
- a source of electric energy: dry cells
The key is a simply push-button switch design for high speed use, and control the flow of electric current. The knobs on the key can be adjusted so that a small movement of the key controls the flow of current precisely.

 

This is how :

Push down the key and the contact point will be touched, electrons will flow through the key from the dry cells to the sounder. The electric current goes through the two coils of wire on the sounder and back to the dry cells. The coils become electromagnets and attract the iron cross piece, which attached to the sounder bar. The sounder bar will be pulled down quickly, hits the frame under it and makes a loud 'click' sound.
To send a message you need a code, most telegraphers use International Morse Code. The letters are represented by combination of dot(.) and dash (-). To send a 'dot', press the key and let go immediately. To send a 'dash' press the key and hold for about the time to say "dash". A dot is a short interval, and a dash is a longer interval.

Now you know how a telegraph works. In the next article I will try to describe how to make a model of telegraph. If you could build them, try to use this International Morse code, like the picture below, to send your message.

I hope that reading the above information was both enjoyable and educational for you. Your learning process should be ongoing--the more you understand about any subject, the more you will be able to share with others.
