What is energy??

Emmm....what is energy..it is not a common topic right? Not all of us can explain the real meaning of energy completely. Actually, energy is the fuel of life. It keeps plants grow, the animals alive including us. It is too general and the real definition of energy is the ability of a physical system to do work, whether than be growing, lifting, moving or sustaining life.
Nowadays human use many kinds of energy. According to biological level, we get energy by eating foods. Where the food came from? They came from plants and animal right? Besides that we have to remind ourselves that energy also produce from the warmth of the sun. But in this millennium era, we have also discovered more and more ways of exploiting energy such as electric motors. These range from wood fires, which create light and heat from the chemical energy stored in plants, to gas power station which electricity from the heat created by burning natural gases.Hence, as the future engineer, we should explore more and think out of the box, how to create more and more effective energy generator...InsyaAllah..

WHAT CAN WE EAT TO FEEL BETTER FAST WHEN WE’VE GOT A COLD??

You know what, when we have got a cold, we can start with a bowl of homemade chicken soup. I never try this because I don’t really like soup actually. But I have to try this way if I’ve got a cold after this..hehe..it is very important to us to know how to get better fast. We can try this food to heal the flu that we got such as orange juice because the vitamin c in the orange may shorten the duration of our cold and help us to get back on our feet. Besides that we also can try to eat oatmeals, bananas, fish and chickens to maintain the organs that make infection fighting white blood cells. Don’t forget about the fruits like apples that contain flavonoids which can strengthen our immune system. So, why don’t you try!i'm so sorry because i cannot share more..not enough time! Bye

CALCIUM IN OUR FOOD

Everyone requires calcium. Calcium is essential for the growth and repair of bones throughout life. Bones mass generally peaks by age 30 to 35. Thereafter, one begins to lose more mass than the body can replace. The reduction of bone mass can progress gradually and painlessly and most people do not know they have osteoporosis until the bone break. This is why osteoporosis is also known as “ The Silent Disease”. Women are more prone to osteoporosis after menopause.
Calcium-rich foods include broccoli, non-fat and low-fat dairy products, nuts, seaweed and seeds. While milk is a good source of calcium, many people are lactose intolerant. Their bodies are unable to digest necessary amounts of lactose, the predominant sugar in milk.
It is not easy to obtain the daily requirement of calcium, and even more difficult for people with lactose intolerance as they cannot consume milk. In cases where the amount of calcium from food is not possible or practical, it is recommended to take a calcium supplement. So my dear friends, we have to remember that calcium is very important to health! lets together make our life longer....huhu

engineering...

Engineering is the discipline and profession of applying scientific knowledge and utilizing natural laws and physical resources in order to design and implement materials, structures, machines, devices, systems, and processes that realize a desired objective and meet specified criteria. The American Engineers’ Council for Professional Development (ECPD, the predecessor of ABET) has defined engineering as follows:
“The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to forecast their behavior under specific operating conditions; all as respects an intended function, economics of operation and safety to life and property.
One who practices engineering is called an engineer, and those licensed to do so may have more formal designations such as Professional Engineer, Chartered Engineer, or Incorporated Engineer. The broad discipline of engineering encompasses a range of more specialized subdisciplines, each with a more specific emphasis on certain fields of application

environment..

The natural environment, commonly referred to simply as the environment, is a terminology that comprises all living and non-living things that occur naturally on Earth or some region there of. This term includes a few key components:
Complete ecological units that function as natural systems without massive human intervention, including all vegetation animals, microorganisms, rocks, atmosphere and natural phenomena that occur within their boundaries.
Universal natural resources and physical phenomena that lack clear-cut boundaries, such as air, water, and climate, as well as energy, radiation, electric charge, and magnetism, not originating from human activity.
The natural environment is contrasted with the built environment, which comprises the areas and components that are strongly influenced by man. A geographical area is regarded as a natural environment (with an indefinite article), if the human impact on it is kept under a certain limited level .This level depends on the specific context, and changes in different areas and contexts. The term wilderness, on the other hand, refers to areas without human intervention.
People nowadays always think lightly about the environment. Some of us do not know about the importance of loving and caring about the environment. We need trees to produce oxygen. We need clean water to drink and we need fresh air to breath. Hence, we have to be more responsible to take care about our surroundings….
