Story of Isaac Newton

Sir Isaac Newton’ and William Stukeley, an archaeologist.After dinner, the weather being warm,we went into the garden and drank tea, under the shade of some apple trees. Newton was inspired to formulate his theory of gravitation by watching the fall of an apple from a tree.

Actual Incident

cartoon version that the apple actually hit Newton's head

1) In 1666, Newton observed the fall of an apple in his garden at Woolsthorpe. Later in the same year he began to think of gravity extending to the orb (sphere or globe) of the Moon.'

2) Newton's memory was not accurate. 3) In fact, all evidence suggests that the concept of

universal gravitation did not spring full-blown from Newton's head in 1666 but was nearly 20 years in gestation.

4) Sometime in early 1680, Newton appears to have quietly drawn his own conclusions.

KOREAN ELECTRONICS INDUSTRY

1. The story of Korean electronics companies started 25 years ago.

2. Today Korean electronics companies have come to own a significant share of the world electronics market.

3. Korean corporations have technologies, manufacturing procedures, capabilities, and infrastructure

4. Major DRAM suppliers in the world.5. High-definition television (HDTV), 6. Microelectromechanical systems (MEMS), 7. Flat-panel displays8. Semiconductor and other electronics equipment

development.

9. Future remains with sophisticated and advanced circuit design.

10. Future competitiveness will require combining all fields

related to electronics manufacture (layout, architecture, systems, fabrication, analog, and others), and that it will take imaginative and resourceful minds and team efforts to achieve interdisciplinary solutions.

1) Cheating is an act of lying, deception, fraud, trickery, imposture, or imposition.

2) Cheating characteristically is used to get an unfair advantage, usually in one's own interest, and often at the expense of others.

3) Cheating implies the breaking of rules (moral).

Story of super-material 'graphene'

Like the graphite in your pencil, graphene is a form of carbon. The difference being that in graphene, the atoms of carbon are arranged in a flat honeycomb pattern, to form a sheet of carbon just one atom thick. 

1. Graphene is likely to make a huge impact on technology in the coming years, as it is thin and super-strong.

2. Offer huge promise for a host of applications from IT to energy to medicine.

3. Could pave the way for powerful new computers, drugs and electronic equipment.

4. Flexible touch screens, lighting within walls and enhanced batteries are among the likely first applications.

5. About 100 times stronger than steel; conducts electricity better than copper.

6. Touted as possible replacement for silicon in electronics7. About 1% of graphene mixed into plastics could make

them conductive .

The ultra-thin substance was invented at Manchester University in 2004 by scientists Andre Geim and Kostya Novoselov. The pair – who won the 2010 Nobel physics prize. Presently, China, the US and South Korea are way ahead in Graphene research.Nationality Number of graphene patent
