Here are ten awesome things that might never have existed without the invention or innovation of black women:

1. Everything good about your phone

Remember the days before call waiting and caller ID? If you answered 鈥測es,鈥� you might be old.

It also had a two-way microphone, which allowed for communication with visitors at the door, and a remote switch that could unlock the door to let people in. If the person seemed unsafe, users could push an alert button to signal a nearby security firm.

6. A good hairbrush

Have you ever seen those old-time movies where women run a brush through their hair 100 times, counting each stroke in what appears to be an unnecessary waste of time? They probably had to do that way back then. Brushes weren鈥檛 as user friendly as they are today, and combing hair was a long and difficult process.

聽was simple yet revolutionary. In 1898, Newman patented her 鈥渘ew and improved hair-brush.鈥� The brush had evenly separated bristles, slots that kept dirt and hair neatly contained, and a detachable compartment for easy cleaning. The artificial bristles Newman used were similar to the plastic ones used today.

9. 3D movies

Seen any 3D movies lately? You know why? A black women: , physicist, inventor, and NASA data analyst. When she wasn鈥檛 busy managing the Landsat program, which has produced millions of images of Earth, she was inventing the technology which went on to become the premise for more advanced TV screens and modern 3D technology.

In the late 鈥�70s, Thomas discovered that concave mirrors can create the and began experimenting with how she could visually transmit the 3D illusion. In 1980, Thomas patented her .

10. Better eyesight

While she may not be responsible for everyone鈥檚 sight, invented a device that drastically improved the process for removing cataracts, which can cause impaired vision and blindness.
