100 Amazing Inventions
86. What is the Apple Pencil?
APPLE PENCIL:
The Apple Pencil
comes with the Apple iPad Pro. It is a stylus, but it is no ordinary
stylus. Long and slender, the device looks and feels like a pencil, and
so, the name is most apt. The Pencil has many uses. It can be used for
taking notes, to annotate documents, to create beautiful graphics, and to
mark up drawings.

The Pencil works seamlessly with an array of apps,
allowing you to draw onto the apps, and unlock other functions. This
pressure sensitive writing tool is both sophisticated, and easy to use.
Press lightly to get a thin stroke, or press harder to get a thicker
stroke. You can even shade, and trace through a regular sheet of paper
using the Apple Pencil.

The device also comes with a built-in lighting plug
that is revealed by removing the Pencil's cap. This allows you to plug
your pencil directly into iPad to change.
All things considered, the Apple Pencil is truly a
remarkable invention.
87. Which is the cheapest and greenest car?
ELECTRIC SUV:
Tesla's Model X is
the world's first luxury electric Sports Utility Vehicle, or SUV. Its most
amazing features are its mind-bending acceleration, gorgeous design, and
amazing rear passenger doors. Tesla calls them 'falcon' doors, because they
lift like the wings of a bird. But most important of all, since it runs on
electricity, it is economical and eco friendly too.
Like all electric vehicles, it is very quiet, and very
smooth. It is convenient and cheap, for it does not guzzle expensive petrol
or diesel. Owners just have to pull into their garage, plug in the car, and
let the battery recharge for the next day's running.
Electric cars are green in that they do not release toxic
fumes into the atmosphere. Their batteries give them a low centre of
gravity, which means that they handle like sports cars. So, it is no
wonder that Tesla's Model X has been hailed as the meanest, greenest,
driving machine on the road today.
88. How, and When, were mirrors invented?
MIRRORS:
The history of mirrors dates back to ancient times
when mankind first saw reflections in a pond of river, and considered it
magic.
At first, polished stone or metal was used in the early
man-made mirrors. Later, glass was used in combination with metals like
tin, mercury, and lead. Today, combining glass and metal is still the
method used in almost all modern mirrors.
The two way mirror was originally called the
'transparent mirror'. There is a silver coating on the glass of a two
way mirror, which, when applied to the back of the glass, renders the
glass opaque and reflective on its face under ordinary light
conditions.
89. Why is it said that Douglas Engelbart was an unsung hero in the
history of computers?
MOUSE:
Douglas Carl
Engelbart was an American engineer and inventor, and an early computer
and Internet pioneer. He is best known for his work on the challenges of
human - computer interaction.

Douglas Mouse |
Douglas Carl Engelbart changed the way computers
worked, from specialized machinery that only a trained scientist could
use. He invented, and contributed to several interactive,
user-friendly devices including computer 'mouse', which revolutionized
the way we use computers.

So, he was regarded as one of the prominent contributors to the
massive development of computers. Engelbart died in 2013.
90. Who invented the first Typewriter?
First Typewriter:
Christopher
Latham Sholes invented the first practical modern typewriter with
his partners Soule and Glidden in 1866. The invention was
patented in 1868, and was manufactured by Remington Arms Company in
1873.

The First Type Writer |
Before the computer, the typewriter may have been
the most significant everyday business tool. After five years, and
dozens of experiments later, Sholes and his associates produced an
improved model, similar to today's typewrites. The type-bar
system, and the universal keyboard were the machines novelty but
he keys jammed easily. To solve the jamming problem, another
business associate, James Densmore, suggested splitting up keys
for letters commonly used together to slow down typing. Thus the
'QWERTY' keyboard was formed.
The first electric typewriter was the
Blickensderfer. In 1994, IBM designed the first typewriter with
proportional spacing.
