1. Scientific Advancement in the Last 50 Years
There has been a significant level of scientific advancement in the last 50 years that
have changed our lives. Here are a few of the changes that have made a big difference
in our world.
Cell Phones
These small gadgets have evolved quite a bit over the past few years and they are now
more popular than ever. They have revolutionized the way we communicate. Over 90%
of Americans use a cell phone of some description. This is one of the most popular new
innovations of the past 50 years. These devices have changed communications so we
can keep in touch whenever we want at the touch of a button. They have also recorded
historic events that would never have been seen without this invention.
Artificial Heart
The ability to extend someone’s life with an artificial heart is a very big achievement.
The ability to provide artificial organs to people who would otherwise die helps us
extend life and bring quality of life back to those that receive these treatments.
Computers/Internet
The PC or personal computer is an immense achievement and one that has completely
transformed our world. We use the PC to work, play games, chat, watch television and
perform other tasks. The computer along with the Internet have changed our world and
brought us closer together with instant communication. The Internet today is very much
a part of our daily lives.
Satellites
Our world stay connected through the use of satellites. We have GPS, radio, television,
global communications, weather tracking, and other satellites that make our lives today
easier and provide us with important information.
Space Travel
Landing on the moon was one of the greatest achievements of the past 50 years. We
receive a new perspective on our world after landing on the moon. This has opened the
door to future space travel and the thought that someday we’ll be able to explore the
galaxy and learn more about our solar system.
Microchips
Without the invention of the microchip we wouldn’t have computers and much of the
technology we use today. We use them in computers, smart phones, calculators, teller
machines, satellites, and many other products. These chips are so small yet so powerful
and they have helped define our modern age.

2. Digital Cameras
The way we take pictures has changed dramatically with the digital camera. Now we
can take as many photographs as we want and manipulate them at home to suit our
needs. Digital cameras have turned us all into instant photographers.
