The Ishango Bone is likely one of the oldest mathematical tools in existence. Sources differ regarding the date of its discovery with some indicating that it was discovered in 1950 while others site 1960 as the date of discovery. The bone was found amongst the ruins of a settlement near Lake Edward that was buried after a volcanic explosion. The Ishango Bone was discovered by geologist, Jean de Heinzelin de Braucort (1920-1998) in the Ishango region of the Democratic Republic of Congo. The bone is believed to be the fibula of a baboon. It measures approximately 10cm-14cm in length and is inscribed with a organized series of notches. At one end of the tool is a sharp quartz edge that is believed to have been used as a writing instrument. The Ishango Bones discovered by Heinzelin de Braucourt are housed at the Royal Belgian Institute of Natural Sciences. Continue reading “The Ishango Bone: Early Tool Used For Mathematic Computations”→
African American Physicist, Dr. Hadiyah-Nicole Green, has been awarded a $1.1M grant to develop her patent-pending cancer treatment using laser activated nanoparticles. Dr. Green currently serves as an assistant professor of physics at Tuskegee University. There are less than 100 black female physicists in the U.S. She earned her masters degree and Ph.D from the University of Alabama at Birmingham. When speaking about her achievements, Dr. Green says she is really no different than anyone else. She also says,
Barrington Irving (1983 – ) developed an interest in flying through a chance encounter when a man in a flight uniform came into to the bookstore owned by his parents. The man asked Irving if he had ever considered a career in aviation. Initially, he told the man that he did not think he was smart enough to pursue such a career. However, the conversation did pique his interest and through this encounter he had the opportunity to sit inside a plane cockpit.
Irving was unable to afford flight lessons right away. So he saved his money and purchased a computer flight simulator game that he used for practice. He continued to save up money until he was able to afford private flight lessons. Irving obtained his pilot’s license at 19. By the time Irving was 21, he had already begin to think about the legacy he wanted to leave. He had lost many friends due to violence or prison and wanted his life to go in a different direction and have a positive impact. He decided that flying around the world would be something he could do to leave a positive legacy. He began to pursue this goal, but faced many challenges for almost 2.5 years. At a cost of $650,000, purchasing his own aircraft would have been impossible for Irving. He decided to approach companies and ask them to donate parts to help build the plane. Eventually he was able to secure all of the parts which were needed.
In 2007, his plane, “Inspiration” was finally ready. The plane had no radar, no de-icing system when he left Miami. His flight around the world would take 97 days and 27,000 miles to complete. Thousands awaited him when he returned to Miami on March 23, 2007. He was then, the youngest person ever to fly solo around the world. This record has since been broken by a 22 year old, Swiss pilot. Irving was struck by the number of young people who had followed his flight around the world. He used this inspiration to start his own non-profit, Experience Aviation. The non-profit serves students in Miami’s failing high schools to teach them about aviation and get students excited by STEM fields.
