Technology is any tool people use to change their environment. Sometimes it changes them as well.

The Wheel
4000
BC
Probably invented in Mesopotamia (modern day Iraq) 6,000 years
ago.
1500
BC
The wheel was used for pottery, carts, and
chariots.
350-now
It was used to create power through water wheels and windmills.
now
We still use the wheel today. Our society would not be
possible without being able to travel by car, train, and
airplane, all of which use the wheel.
Nobody knows who invented the wheel. It is one of the most basic
technologies ever invented. It was preceded by 194,000 years
of walking everywhere.

The LensNobody knows who invented the
lens. It depended on the invention of glass somewhere
around the 3000 BC (5000 years ago!)
700
BC
The oldest known lens seems to have been made around 2,700
years ago.
1284
AD
Around 1240 AD an italian figured out the lenses could be made
into glasses. Many, many people depend on
glasses today to help them see and do their
jobs.
1609
Around this time the telescope and the microscope were
invented.
1610-now
Telescopes changed our understanding of space,
eventually leading to satellites in orbit and a
man walking on the moon.
1860s
Microscopes led to the discovery of germs and vaccinations to prevent diseases. Louis Pasteur
is credited with this discovery.
now
Satellites allow us to predict the weather and send phone
calls, television, and internet access to all parts
of the world. Medicines have allowed us to live longer,
healthier lives. All because of a lens.

The Printing Press
1440
AD
The printing press allowed large numbers of books to be printed quickly and cheaply.
1440
More books meant more educated people. It also meant scientists could
share their ideas quickly and easily.
1500
Widespread publishing of the classics helped
develop the Renaissance in Europe.
1700s
More educated people led to the rise of
democracy.
1440-now
Scientific discoveries came more quickly and
built on each other, resulting in the inventions and
knowledge we use today.
now
In some ways, the printing press started the first
internet: ideas posted on pages and shared with
others. Our world would be very different without all of
that knowledge.
Invented by Johannes Gutenberg around the year 1440 in Italy, it was the first printing press with
moveable type that allowed a printer to quickly set up a new page and still be able to reuse
the letters. Gutenberg depended on the inventions of the
alphabet, paper, and the olive press to make his idea work.

The First BatteryAlso called the Voltaic Pile, it was
invented by Alessandro Volta in 1800 in Italy. He built on the
work of scientists, including Oto von Guericke, Benjamin Fraklin,
and Luigi Galvani
1800
AD
The first battery provided scientists with
the first continuous source of electricity to
study.
1800 -now
This led to the development of all sorts
of uses for electricity, including better
batteries...
1830 s
...the electric motor (still used today in things like refrigerators, washing machines, and some
vehicles)...
1844 ...the telegraph...
1879
...and the long-lasting electric light bulb.
now
Just about everything we do today, depends on electricity. Without
electricity we have no computers, no iPods, no cell phones, no tvs, no cars, no
microwave ovens, no internet, no...
