Saying
a
instead of
one
: you can say
a hundred and thirty
(130) but NOT
three thousand a hundred and thirty
(3,130): say
three thousand one
hundred and thirty
. People often use
a
instead of
one
in conversation,
but it is better to use
one
in technical contexts.
Saying the number 0
in mathematics, science and technical contexts
:
Br E:
Say
nought
or
zero
.
Am E:
Say
zero
.
In temperatures
:
Br E
: Say
zero
to refer to freezing point (0° Celsius or -32° Fahrenheit).
Am E
: Say
zero
to refer to 0° Fahrenheit.

Writing full stops and commas in numbers
Use a full stop (.) to separate the main part of a number from the decimal
part (the part that is less than 1).
5.074 means “
five point nought seven
four‖.
Say
point
to refer to the full stop. You can use a comma (,) in large
numbers to separate the hundreds, thousands, and millions. 5,074
51
me
ans “five thousand and seventy-four”. In British English, spaces are
sometimes used instead of commas (5 074).
3. a) Write down the word combinations denoting the arithmetic signs:
«+»; «–»; «:»; «x»; «=».

Big Progress on the Little Things
Let’s take a step back and praise three unsung trends in consumer
electronics
In the trenches
of consumer technology, there‟s plenty to complain
about. Today‟s cell-phone contacts are exorbitant and illogical (why has
52
the price of a text message doubled in three years?). Those 15-second
voicemail instructions still seem to last forever and use up our expensive
airtime (“When you have finished recording, you may hang up” – oh,
really?). And laptop batteries still can‟t last the whole day.
But here and there, in unsung but important corners of consumer tech,
some long-standing annoyances have quietly been extinguished. These
developments deserve a lot more praise than they‟ve received.
Take the megapixel race. For years the camera industry brainwashed
us into believing tha
t a camera‟s megapixel measurement somehow
indicates the quality of its photographs.
It doesn‟t. A lousy photo still looks lousy – even at 45 megapixels. In
fact, more megapixels can mean
worse
images because the more photo
sites (light-sensing pixels) you cram onto a sensor, the smaller they get,
the less light they collect and more heat they produce, resulting in “noise”
(random speckles).
The megapixel myth was a convenient psychological cop-out for
consumers, who longed for a single, comparative statistic like miles per
gallon for a car or gigabytes for an iPod. The camera companies played
right along because it meant that they didn‟t have to work on the factors
that really do produce better pictures: the lens, the software and, above
all, the sensor size.
In the past two years, though, a quiet revolution has taken place. The
megapixel race essentially shut itself down. The megapixel count came
to rest at 10 or 12 megapixels for pocket cameras, maybe 16 or 18 for
professional ones
– and the camera companies began putting their
development efforts into bigger sensors. Cameras such as the Canon
S95, the Sony NEX-C3 and Micro Four Thirds models pack larger
sensors into smaller bodies.
Another example: power cords. We‟ve all griped at one time or another
about our drawers full of ugly, mutually incompatible chargers. Every
53
new cell-phone model, even from the same manufacturer, used to
require a different cord (and car and plane adapters), racking up another
$50 per phone sale per customer.
And then, one great morning, electronics executives must have
confronted themselves in the mirror, filled with shame, and decided to
shut down that extortionist, environmentally disastrous profit center.
In Europe, for example, all the major cell-phone makers agreed to
standardize their cords. Today every phone model uses exactly the
same interchangeable USB power cord.
Similarly, the micro USB‟s cousin, the mini USB, has been making its
own conquests. Now you can charge up most Black-Berries, Bluetooth
headsets, e-book readers, music players and GPS receivers by
connecting a USB cable to either a power plug or your laptop. You can
also use the same 30-pin charging cord on every one of the 200 million
iPhones, iPads and iPods touches ever made.
Finally, it‟s time to give thanks for the most important revolution of all:
the simplicity movement.
For decades the rule in consumer tech was that whoever packs in
more features wins. Our gadgets quickly became complex, cluttered and
intimidating.
But then came the iPod, a music player with
fewer
features than its
rivals (no radio, no voice recorder); it became the 800-pound gorilla of
music players. Then the Flip camcorder
– so simple, it didn‟t even have a
zoom
– snapped up 40 percent of the camcorder market (until Cisco
bought and, inexplicably, killed it). And the Wii, a game console whose
controller has half as many buttons as the Xbox‟s or the PlayStation‟s
and whose graphics look Fisher-Price crude, became a towering
success, outselling its rivals year after year.
Simplicity works because it brings you happiness. You feel a sense of
immediate mastery. Simplicity as a design goal makes life harder for the
54
gadget makers, of course, because designing next year‟s model is no
longer as easy as piling on new features. But simplicity is a goal worth
sweating for.
In other words, some trends demonstrate maturity, brains and good
taste on the part of the manufacturers; it‟s worth taking a moment to
celebrate them.
Okay, that‟s enough. Now let‟s go back to complaining.
