7 inventions that help the whole world understand just how great people of color are

All lives are equally precious, but racism for centuries has made that saying lose its value. People of color have long suffered from discrimination, both in status, interests and the conduct of everyday communication. But perhaps many people don't know that without the colored people, the many inventions and utilities we are using today will never exist.

1. VoIP - Voice transmission system on Internet protocol

It sounds complicated, but basically when you make a call through applications like Skype, Facetime, Google Hangouts . it is VoIP. And the inventor of VoIP is Dr. Marian Croak. She is Google's vice president of engineering, and is also a black person.

Dr. Croak has been honored as the foundation and developer of the VoIP system - a system that allows users to communicate by voice or image via the internet. Currently, nearly every feature of VoIP is developed by Croak, and it is applicable to a multitude of other platforms around the globe.

2. GPS

When you arrive at an unfamiliar new location, how do you find your way? If you simply open your phone and look up the map, you owe Dr. Glady West a thank you. More precisely, the whole world must thank Dr. West, a black woman, for saving us most of the time to locate and find our way.

West graduated from a male-dominated university, then worked at the Naval Surface Combat Center, and was one of only four black women to work there. Her mission is to analyze data from satellites, synthesized in the shape of the Earth. Eventually, she programmed an IBM computer to create an even more accurate computing system - the basis of today's GPS.

3. Animations (GIF images)

Netizens today use animated images (GIFs) to express their emotions a lot, just like a routine. Sometimes a story, just drop in a reasonable GIF is more than enough for friends to laugh to tear the mouth.

If you are also among those who are passionate about GIFs, you need to thank Lisa Gelopter - a black computer expert. At CompuServe, Gelopter laid the foundations for GIF images, developing an extremely optimized animation system for the whole world to use comfortably today.

In addition, there are many other inventions applied in countless areas of life today, and their authors are women of color.

4. Iron

The author of the table you use for ironing every morning is Sarah Boone - a black inventor.

5. Sanitary pads

Sisters in the world really need to be grateful to Mary Beatrice Davidson Kenner. She is also of color.

6. Telephone exchange system

An extremely professional system you always hear when calling to any company's switchboard. Its author is Shirley Ann Jackson, physicist, inventor and also the first black woman to receive a doctorate from the MIT Institute of Technology (United States).

7. 3D movies

Dr. Valerie Thomas - inventor, physicist and data analyst at NASA who laid the foundations for 3D movies. Without her, director James Cameron's Avartar would never have become a legend.
