  • I discovered that Margaret E. Knight invented the flat-bottomed paper bag was invented in 1853.
    This invention is very beneficial to people all over the world because it is very easy and it takes less energy to make them and It also helped and influenced other people to be creative and also produce similar products similar to the flat-bottomed paper bag. It helps in carry small items like gifts, candies and other light weight items.

    1. I'm not entirely sure Margaret Knight created the paper bag itself, openminded_beetle. Can you tell us where you found this information?

  • I found that, according to Bluehost blog Dr. Shirley Jackson is the first Black woman to graduate with a Ph.D. from the Massachusetts Institute of Technology (MIT).
    Her research in telecommunication led to the invention of technology such as fiber optic cables, She is also a leading developer of call waiting and caller ID on mobile phones.

  • Welcome!
    A few weeks ago, at a university in my country, a woman "Baraa Abu Asaker" invented a medicinal compound that could definitively treat "pancreatic cancer".
    And it was granted a "patent" certificate...!This is of course important, especially as it is a "medicine" or, in general, a "treatment".
