It was the day before Thanksgiving. I had to beg and beg for my Dad to make his special Cool-whi & Pound-cake desert. He told me he would think about it. I asked him an hour later if he had thought about it. He said he did and he would make it. I thanked him and asked him to make sure there would be enough for everyone.
I then went and helped Mom set up the table. I told her I wanted to help with Thanksgiving table. She agreed and we soon finished.
Then I went over Dad to help with the desert. I helped mix the cool-whip. He warned me not to dip my finger and taste the desert. It did taste very good though when I tried anyhow. My dad then put the desert in a bowl and put the bowl in the fridge. We promised Dad, me and my little bother of a brother, wouldn't eat it before morning.
It wast late in the night by then. Dad wanted to go to sleep. I wondered if my school would like the desert. I couldn't stop thinking about it. I would wait until the next morning. Dad woke up. It was time to have a feast. It was soon the hour of the desert. All the desert was gone in 10 minutes.
I told my Dad he would have to make another one for School.

The collective list of distinct ideas or questions your writing will set out to explain or answer.
How you have organized your story. The table of contents and chapters are some ways of organizing the story or writing. "flashbacks" in films is another way of organizing an idea.
The voice is the way a story is being told: is it being told from the writers perspective, or is it told from the perspective of one of the characters or is it told as a "dialogue" and interaction between the characters.
Another way voice is being explained is how a writers "personality" or way of writing and his/her beliefs show up in the writing indirectly through style.
How smartly, beautifully, plainly, or however which suits the author the words are employed to convey meaning.
There are certain writers where this is taken to the utmost art form such as the plays of "Shakespear" a truly remarkable achievement.
This is an extension of how words are crafted into sentences.
It is about rules and punctuation and grammar.
For example a "haiku" has an exact format and convention and so does a "Sonnet"

Yes, for wireless communications lasers can be used. For example satelites can send communications using lasers.
Yes, indeed. Most of the internet runs on optical fibers. There are optical fibers under sea beds that carry electronic messages between continents.
"Tele" means far and "vision" means sight. So television meant seeing from a distance.
cellphone tv internet
Electricity travles very fast, almost instantaneously. So messages sent through telephones travels much faster than paper. This allowed people to communicate faster. This has a big impact on early wars and also in saving lives as danger can be communicated that much faster for example of an approaching hurricane.
Leonardo da Vinci's studies, drawings, and never-finished inventions involving flight were revolutionary in design to say the least. It is debated whether da Vinci successfully flew using any of his machines, but even if they never left the ground in his time; modern day parachutes and helicopters are very similar to Leonardo's designs from hundreds of years ago. This is interesting because most of his work was not uncovered until the 19th century, after all the machines were reinvented. Leonardo's study of flight started with flapping-wing mechanisms, but after he discovered the futility of human powered and coordinated flight, he turned his eyes to the birds. He studied, watched, and dissected birds and bats, trying to discover what enables them to fly. After his writings on birds his research shifted to glider based flight, rather than further pursuing human powered wings, or the aerial screw (the ancestor of the helicopter).
Leonardo Da Vince (1452 to 1519) drew lots of designs for flying machines.
Starting with the first human flight by Wright brothers in 1903, it would make 100 years of flight in 2003. So we have been flying for more than a century.
Henry Ford in 1913 mass produced many cars in a factory so that they are cheap enough for lot of people to buy.
Wright brothers in 1903.

Satelites are man made machines that circle the earth. They help take pictures of the earth and carry telephone, internet, and tv data.
Voice from us is converted to an electrical signal in the telephone mouth piece
The electrical signal travels through the wire to a central telephone station and gets routed to the other telephone on the other side
The speaker converts the electrical signal back to voice which the person on the other end hears.
House telephone use electic wires to carry telephone messages.
Internet uses cable wires and optical fibers to carry messages.
Satelites use radio waves (kind of invisible light)to send messages to earth and to aeroplanes and ships
US Post office Telehone Email
Communication means exchanging messages.
By cutting away the excess fat collected in the blood vessels in the heart, lasers can help patients with clogged arteries.
Yes. Eye sight can be corrected by using lasers using a surgical procedure.
Doctors make a small incission in a patient similar to a key hole to insert an optical fiber or a small medical instrument and by using the light from the optical fiber and a camera they can conduct surgeries. This will save the patient from a large cut and prevents bleeding and allows faster recovery.
Optical fibers are used in medicine for such things as key hole surgery.
Optical fibers are heavily used in carrying the electronic data through internet.
Lasers are used to unclog arteries that carry blood in the heart to prevent heart attacks.
Lasers are used for eye surgeries.
Lasers are used for communicating messages through light.
A laser is a concentrated beam of light.
Optical fibers are tiny but long tubes that can carry light with them.
Magnetic Resonance Imaging. It uses magnetic fields to take pictures of soft tissues and blood vessels.
