Special pens three-dimensional image

While the touchscreen device has now spread everywhere, but very few that allows a user to draw in two-dimensional surface. Another concept which has been present even allow a user to draw sketches of obtaining a three-dimensional shape of an interactive surface. Devices were developed by Lee and Hiroshi Ishii Jinha, MIT media lab.

System in the device using an input device that can be folded to manipulate the 3D image directly. Tool for 3D drawing in 2D surface is a small pen that can be turned into a digital pen to the screen when pressed, gives the illusion like being inside the space virtual.Dengan move the pen to the higher layer and gives a picture, then the user can create three-dimensional image. Assisted with the existing system in the pen, the user can also draw a cube, cylinder and three-dimensional object other.

^ Modern engineer

Television, Telephone, Synthetic textile, Refrigeratorring air, and Electric light bulb is some of so much many modern developments we enjoy and We accept to what existence. Many one who will not realize that engineers in charge of those progresses. Engineer profession group continuously educe method, Ingredient, and System comprehensive so that thereby we are easily get freshment and Ease is not enjoyed in 1 and 2 generations that then.

Not easy to find a engineer definition that approved by all experts in the field of this. Enough, Time goods, If said that engineer is one who practise mathematics science and Batural sciences especially physics and Chemistry, As ingredients the result and Energy sources that provided by nature has been allocated for human. Beside mathematics science background, Physics, and Chemistry soerang engineer must has imbaginasik, Astuteness, and Reasonable evaluation if he is supposed can design building or Economical engine, Durable, Safe and Interesting.

There firm difference between science and Engineer. Scientist usually only interested in erudition development from some natural worlds aspects. Scientist wants to detect why a certain happen but Unnecessary interested to worthwhile applications from the invention. Ilmuan usually doesn't creat a product likes a unti power station trubin steam. Idea and Konsepsi those scientists their product. Scientist mengisolasi new chemical element, Canvassing atom, and Making field inventions like dietetika and Termodinamika. They look for to answer terdap question about space and or nuclear physics.

On the contrary, Engineers involved with scientific eruditions intelligents applications to finish technical problem. They want to know not only why and How a certain work but Also how a certain that made to work better and Economicaler. Engineer must tanggap cost, Because new projects can said practise if every rupiah that invested membuahkan satisfying result. Furthermore, Engineer responsibles absolute towards general welfare.

All these did not mean that found wall impermeable between science and Engineer. Actually, Engineer and Scientist even often cooperate in bew invention applications first stage.
General engineer area

In earlier paragraph, Showed to how engineer scope has been expanded so that permanent in line with science new inventions and Technology. Now, This profession is widely diversifieds to seven generals areas:
1. Aviation engineer;
2. Chemistry engineer;
3. Civil engineer;
4. Electricity engineer;
5. Engine engineer;
6. Mining engineer; And
7. Nuclear engineer.

These areas not apart and Differ, but Mutual equip and Melting in certain cases.
Aviation engineer
This engineer branch is especially relates to vehicle aviation special problems berawak and Unmanned winged aeroplane, Helicopter, Ballistic missile, Guided missile, and Space vehicle.

Aviation engineer deals with power lifts that underpin aeroplane in aviation, Fascination that prevent aviation, and Pushing power from activator centre that need to overcome fascination. They estimate bellows load, Undergone during when has aeroplane met vertical air-current. They also calculate load influence that evoked when land, In tool pendarat for aeroplane that land and In base lambung, or Pontoon, For sea aeroplane. Aviation with high-speed brings special problems, Among others, High-speed causeses fascination growing larger because air wave formation that move very fast. Air vehicle designeds in such a manner so that guarantee balance and Control in all condition flies.

Many complex problems berhungan with bodies structures that must solved. If aeroplane body or Wing brokens although few in aviation, Will happen drastic changes in aeroplane aerodynamics strength so that aviation becoming not may be. Engineer must design a strukstur that will creat good maximum strength also heavy minimun.

Test try to fly aeroplane must be planned and Carrieding out according to be careful and Circumspect. Engineer designs, Educe, Turning on test device tries. They leads test tries, Interpretinging the result, Making report, Implying plan change where necessary.
Chemistry engineer

Chemical enginer change chemistry laboratory inventions are commercial ingredients useful. They creat new ingredients and Finding new use for sometime later. They also develop new production process.

Chemistry engineer serves good also different chemistry process industrial. There difference mendasar between second this industrial group is chemistry industrial deals especially with chemistry ingredients maker like sour, Alkali, Blasting material salt, and Synthetic suite.
In chemical process industrial, the production end result not that estimated upon which chemistry. Raw material according to mendasar changed to pass modification process according to physics or Even also chemistry so that produce industrial ingredient likes paper, Glass, Paint, and Petrol beroktan tall. Engineers now creat preservative that can prevent to grow it mushrooms in woods. They have educed gas in bottle, Heat value 2 or 3 batural gas hot times and Can used for household and Industrial. Refinery produces petrol, Kerosene, Fuel, and Lubricating oil from petroleum. From what remained from this petroleum, Engineers regulate candle maker manner, Perfume, Petrolatum, and Stone charcoal (coke). They have developed detonator ingredients that certifiable like kordite, TNT, PETN, RDX, and Amatol.

Big contribution to industrial penepakan meat, Food preparation, and Canning has been made by chemical enginer. They have created fertilizer, Glue, and Cleaner flour from leavings meat package process ingredient. Imitation food-stuff maker, Liking margarine and Ingredient kinds penyedap, Swiftly bloom because dikembangkannya new process by chemical enginer. They have enlarged canning industrial product with prepare preservative ingredients to watch over original colour and Penyedap food.
