they become smaller and hold even more, they will
definitely be a vital piece o f technology, any student
or practitioner would need.
Wi-Fi & Bluetooth speakers: This startling
Wireless speaker systems let you play music stored
on a phone, tablet,
media player, or computer that’s
across the room or even elsewhere in the house. Most
models use Bluetooth wireless technology, which
works with a wide range o f mobile devices. It is also
improved to fit the current tendency to shrink in size
but burst with power. Now, no need to plead for help
if you are organizing your presentations, workshops
and etc.
Smart watches: Pebble officially launched in 2013,
is the first smart watch. The designers o f this device
realized that a mobile phone is more useful if you
don’t have to take it out of pouch. Besides the common
functions o f a classic watch, it can be connected to the
Smartphone
or tablet, with a simple Android or iOS
application. This way, the watch will give you access
to lots of information besides the time of day, such
as missed calls, messages, and emails. The device is
connected with an app store also, so the developers
could create other applications that would make
Pebble even more interesting and useful.
Touch screen LCD displays:
Almost every device
has one - from modern washing machines and
refrigerators to TVs and tablets. Liquid crystal displays
are cheap, slim and light. TVs and monitors aren’t now
as fragile as the old ones. The portable gadgets of the
century are so small that there is no place for all the
buttons and a now a single button usually has more
than one function. Without a display people would get
easily confused. Add a touch sensitive padding on top
of the display and you get a whole new product!
Air conditioning: It keeps you warm in the winter
and cool in the summer. It refreshes the air and can
deal with the moist air which is responsible for the
unhealthy mould. The air conditioner helps people
who are sensitive to high temperatures to carry out
the daily routine normally without the fear of fainting
or abnormal blood pressure.
R: Hello, Dono. Where are you going?
D: Hi, Rustam. I’m going to he library. I am to find
the information about the
scientists and their great
works.
R: Oh, I have some information about them. If you
want, I can give you.
D: That would be great. Do you have them with
you?
R: Yes, in my computer. Let's sit over there and I
will show you.
D: O.K.
R: Here is. Do you know who is Alfred Bernhard
Nobel?
D: Hm, nothing more than Nobel Prize.
R: Yes, the prestigious Nobel Prize is named
after him. He invented dynamite in 1867 and it was
accidental invention. Nitroglycerine was becoming
a widely produced explosive material at the time,
largely due to the fact that it was far more powerful
than it predecessor, gunpowder.
But the problem was
that nitroglycerine was unstable, and it regularly blew
up people and buildings without warning. Like many
at the time, Nobel realized that nitroglycerine would
be a lot more useful if they could only find a way
to make it, you know, not explode randomly. While
working in a lab with a vial of nitroglycerine, the
vial slipped out o f his hand and hit the ground. After
recovering from the initial shock and surprise that he
hadn’t been blown to bits, Nobel soon realized that he
owed his life to the sawdust
on the ground where the
vial had landed, which absorbed the liquid when it hit
the ground.
D: Oh, I didn’t know about it. Let’s see who is
the next scientist with his invention that changed the
people’s lifestyle.
R: John Walker. Do you know him?
D: To tell the truth I don’t know him.
R: Well, he is an English pharmacist, in 1827 he
invented the matches. He noticed that the stick he’d
been using to stir the pot o f chemicals had a dried
lump on one end. Instinctively, Walker tried to scrape
the substance off the end of the stick. Although not
containing phosphorous, the mixture of antimony
sulfide, potassium chlorate, gum, and starch was
reactive enough that when he dragged it across the
floor, the stick burst into flame. And the next one is
John Stith Pem berton...
