3. Using technology
• Technology is the practical
application of scientific discoveries.
This can mean discoveries such as
electricity or inventions such as 3-D
printer. Most technological advances
have taken place since the everything
was produced by hand or in small
workshops. The industrial Revolution
led to the mass production of items in
huge factories which employed
hundreds of people. In the last 50
years, the Digital Revolution has
changed the way people work and
communicate.

4. 3D printer
• A 3D printer is a type of industrial robot
which uses computer software and
imaging techniques to reproduce three-
dimensional objects. Layer after layer of
materials are laid down until the final
object is created. The advantage of 3D
printers is that they are relatively small,
cheap to use and can accurately
reproduce almost any object. One of the
most exciting uses is the ability to
reproduce artificial limbs. This would be
especially beneficial in countries with
limited access to medical services.

5. Tranport
• The last hundred years have seen huge
advances in transport systems.
Cars,(Tesla) high-speed trains and
urban transport such as trams and
metro systems, have all seen major
improvements. However, perhaps the
most amazing advance has been the
installation and maintenance of the
international Space Station. The Space
Station orbits the Earth at a distance of
about 400 kilometres. Soyuz space
rockets dock with the space station,
bringing supplies and crew members to
this complex laboratory in space.

6. Medicine
• Advances in medicine have saved
countless lives. Drugs such as antibiotics
and preventative medicine such as
vaccinations have improved health and
extended life expectancy. Nowadays,
advances in organ and limb transplants are
helping the sick and disabled become more
mobile. Improved diagnoses, genetic testing
and early intervention are helping to combat
illnesses such as cancer and heart disease.

7. Communication
• Communication have come a long way since
Alexander Graham Bell invented the telephone.
• Today, smartphones connect us to the internet
using likely to communicate using free messenger
services than talking on the phone. In the
workplace and at home, video calls using
computers or smartphones have become the norm;
something which even 20 years ago belonged to
science fiction. Mobile phones first became
available in the 1980´s; today, almost everyone has
a mobile phone.

8. Construction
• There have been some huge building projects over
the past 100 years. These include the Channel
Tunnel that links Britain with France by high-speed
rail; Palm Jumeriah, the world´s largest man-made
island, off the coast of Dubai, and the Burj Khalifa,
the world´s tallest building , also in Dubai.
Improved materials and the use of computers in
architecture have allowed engineers to complete
huge megaprojects which have transformed cities,
and in some cases whole countries.
