Everyday Inventions
The Wonder of Human Ingenuity
The
modern world is full of useful objects that were invented by someone, from the
refrigerator in our kitchens to the smartphones in our pockets. Each invention
is an example of the creative power of the human mind. Where do inventors
derive their inspiration to create useful things? To find out, here are three
inventions that we often use without thinking about their origins. The
inspiration behind each of these inventions came from different sources.
1.
to take from something
Our
first example is the shopping cart. Sylvan Goldman was a grocery store owner. Like
most businessmen, he wished that his customers would buy more so that he could
make more money. He knew that if they Could carry more merchandise easily as
they were shopping, then his sales would go up. While thinking about the
problem one night, he had an idea. Working with a local handyman named Fred
Young, he designed the first shopping cart. Today, retailers who use shopping
carts sell more goods and make more money than those who do not. ¶Without
the desire for making money as a motivating force, many inventions would never
have been invented.
Nature
has also inspired inventors throughout history. This is what happened to
inventor Georges de Mestral one day. While hunting with his dog in the Swiss
Alps, he noticed how the burrs of certain plants stuck to his clothing and to
his dog's fur. After examining them under a microscope, he found they had tiny hooks
that could easily attach themselves to the fibers
of clothing or animal hide. For the next 10 years, de Mestral searched for the
best way to produce and manufacture his idea. The result of his original
inspiration was Velcro, which is used in many modern objects, including
sportswear, shoes, automobiles, and even space suits.
2.
products that people buy and sell
3.
a person or business that sells products to the public
4.
a thread or threadlike material
Jacob
Davis, on the other hand, was a tailor living in California in the 19th
century. One of his customers couldn't stop ripping the pockets off of his
pants during work. Thinking about ways to make the pants stronger, Davis had
the idea of reinforcing the pockets with copper rivets. This simple idea proved
very successful. Soon, other tailors began copying his idea, and Davis had to
patent his invention. As we can see, the simple need to solve a problem can
stimulate inventors to find creative solutions. If you have a favorite pair of
jeans that has lasted for years, then you have Davis as one of the people to
thank for it.
5.
to tear something quickly and forcefully
6.
to strengthen or add force to something
7.
to get a legal document that allows the exclusive right of making or selling an
invention
8.
to encourage something to develop
These
examples show us that there are at least three possible inspirations for human
creativity in the world of inventions---profit, nature, and necessity. The quest for cash has driven commercial
success since merchants first began selling their products thousands of years ago.
No doubt, the entrepreneurs of the future will continue to breathe new life into
the economies of the world with fresh ideas and inventions. How many of their
creations will be inspired by natural phenomena? The world's problems require
creativity and we can expect ingenious many solutions in the future.
9.
a mission, adventure, or pursuit that is often dangerous and/or difficult
10.
someone who organizes or runs a business to make money, often in a way that is
financially risky
11.
cleverly creative, inventive, or original
3 Post-reading
I. Reading Skill: Identifying Topic
Sentences
Most
paragraphs contain two organizational elements: 1) a topic sentence that
summarizes the paragraph's main idea and 2) details that support the main idea.
Knowing how to identify these two elements is a critical part of developing
good reading skills, and will help you understand the broad theme or message of
a text in its entirety. In this unit, we will focus on identifying topic
sentences.
A
topic sentence is a sentence that tells the reader in a general way what the
paragraph is about (i.e., the main idea). It organizes the paragraph and acts
as a core from which the paragraph develops. Although the topic sentence is
often the first sentence of a paragraph, it can also be found in the middle or
at the end.
To
identify the topic sentence, just ask yourself "What is this paragraph
about?" Continue to ask yourself that question as you read the paragraph
until the answer becomes clear. Sometimes you can spot the topic by looking for
a word or two that repeat. Here is an example:
In the West, it is
considered healthy and sexy to have a nicely tanned body. By contrast, in the
East, a fair complexion is essential to looking beautiful. As the Chinese
saying goes, "One white complexion hides three flaws." Whether you
prefer dark or light skin is your choice, but protecting your skin from harmful
UV rays should always be a priority.
In
this paragraph, we see that the first sentence cannot be the topic sentence
because it does not summarize the entire paragraph. In other words, the
paragraph is not entirely about "tanned skin" or the Western concept
of beauty and health. The same is true for sentences 2 and 3. Instead, it is
from the idea of the last sentence that the first three sentences develop.
Therefore, the last sentence is the topic sentence.
