Technology Introduction

Technology is the making, usage, and knowledge of tools, machines, techniques, crafts, systems or methods of organization in order to solve a problem or perform a specific function. It can also refer to the collection of such tools, machinery, and procedures. The word technology comes from Greek, meaning ‘art, skill, craft’. The term can either be applied generally or to specific areas: examples include construction technology, medical technology, and information technology.

Technologies significantly affect human as well as other animal species' ability to control and adapt to their natural environments. The human species' use of technology began with the conversion of natural resources into simple tools. 

Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale.

Using Technology To Enhance Humans

It’s a well-known fact that technology can improve our lives. For example, we can reach anyone and anywhere with our cell phones. And people who can’t walk after an accident now can have smart prosthesis to help them. But what about designing our children on a computer or having a chip inside our brain to answer our email messages? Are we ready for such a future? Many researchers are working on the subject. And as a professor of neuroscience said, “We can grow neurons on silicone plates; we can make the blind see; the deaf hear; we can read minds.” So will all we become cyborgs one day?

Technology and Human

Technology is a broad concept that deals with a species' usage and knowledge of tools and crafts, and how it affects a species' ability to control and adapt to its environment. Technology is a term with origins in the Greek ‘technologia’— ‘techne’ (craft) and ‘logia’ (saying). However, a strict definition is elusive; ‘technology’ can refer to material objects of use to humanity, such as machines, hardware or utensils, but can also encompass broader themes, including systems, methods of organization, and techniques. 

The human race's use of technology began with the conversion of natural resources into simple tools. The prehistorical discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. 

Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact on a global scale. However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history from clubs to nuclear weapons.

                                                          

Human's limitations

Although humans can do many things, there are things that humans are not able to do. There are limitations to human’s abilities. For example:

• we can memorise a telephone number but it is difficult for us to memorise 20 telephone numbers without writing them down.
• we can try to jump as high as possible but it is difficult for us to touch the ceiling.
• we can read the writing on this page easily from a near distance but we can not read the writing from a far distance, for example, 20 m.
• we can hear a sound from a short distance but we will not be able to hear a sound from a very long distance, for example, 500 m.

Five sensory organs

Humans have 5 sensory organs namely the eye, the ear, the nose, the skin and the tongue. Humans use these sensory organs to do various things.

·        The eye enables humans to see things.

·        The ear enables humans to hear sounds.

·        The nose enables humans to smell.

·        The tongue enables humans to taste.

·        The skin enables humans to touch, feel pressure, pain and heat. 

Human's abilities

Humans can do various things by using their brain, body and sensory organs.

Humans use the brain to to carry out various activities, for example, to think, memorise, calculate, learn new things and control body movements.

Humans use theirs body or parts of their body to do various things such as walking, running, climbing, jumping, swimming or carrying objects.

Technology

There are limitations to humans’ ability to do things. Technology is used to make various devices that help humans to overcome their limitations. The development of technology has made our life easier and more comfortable. Technology must be used wisely in order to benefit mankind.

 

Technology is an absolute need we cannot escape from. Let’s just say, it has a very big role in most aspects of our lives. In other words, it answers most of Mankind problems. Across centuries technology evolves. The importance of technology is aiming for comfort of use in whichever form it is. It always directs for easiness in life.

What's the difference between a comet, asteroid, meteoroid, meteor and meteorite?

Read on and find out!

A comet is a relatively small solar system body that orbits the Sun. When close enough to the Sun they display a visible coma (a fuzzy outline or atmosphere due to solar radiation) and sometimes a tail.

A asteroid is a small solar system body that orbit the Sun. Made of rock and metal, it can also contain organic compounds. Asteroids are similar to comets but do not have a visible coma (fuzzy outline and tail) like comets do.

A meteoroid is a small rock or particle of debris in our solar system. They range in size from dust to around 10 metres in diameter (larger objects are usually referred to as asteroids).

A meteor is a meteoroid that burns up as it passes through the Earth’s atmosphere. If you’ve ever looked up at the sky at night and seen a streak of light or ‘shooting star’ what you are actually seeing is a meteor.

A meteorite is a meteoroid that survives falling through the Earth’s atmosphere and colliding with the Earth’s surface.

Comets Introduction

Not long ago, many people thought that comets were a sign that something bad was about to happen to them. People didn't understand how objects in the sky moved, so the sight of a comet must have been very disturbing. There are many historical records and works of art which record the appearance of comets and link them with terrible events such as wars or plagues. 

Now we know that comets are lumps of ice and dust that periodically come into the center of the solar system from somewhere in its outer reaches, and that some comets make repeated trips. When comets get close enough to the Sun, heat makes them start to evaporate. Jets of gas and dust form long tails that we can see from Earth. These tails can sometimes be millions of miles long.
