You can eliminate the need for stronger commercial cleaners by using this cleaner weekly. Back up important data and consider a factory reset if you need a complete refresh. When Mae Jemison peered back at Earth from the space shuttle Endeavour, she felt a sense of unity – with her hometown of Chicago far below, with every star in the galaxy and, importantly, with her childhood dreams of becoming a scientist. George Washington Carver was a scientist and inventor best-known for discovering 100 uses for the peanut, but that’s only the tip of the iceberg in his remarkable life. Throughout his career, the Harvard- and Columbia-educated scientist has repackaged complex theories and universal mysteries into essays, presentations and books aimed at laypeople. Frustrated that no major American university would hire him because of racism, Just relocated to Europe in 1930. Once there, he wrote the bulk of his 70 professional papers, as well as two books. But West was hired by Bell Labs right after graduating from Temple University. That was until he met the right teacher who opened a numerical world to him. Bath became the first African American to complete a residency in ophthalmology in 1973, and the first woman to join the ophthalmology department at UCLA in 1975. Using the laserphaco probe she devised, she was able to restore sight to patients who had been blind for as long as 30 years.

In the years that followed, Susan Carver taught him to read and write because local schools did not allow Black students. In 1988, she became the first Black female doctor to receive a patent for a medical purpose. His soybean compound research led to a number of patents and pioneering medications like synthetic versions of the female hormone progesterone and the steroid cortisone (used to treat rheumatoid arthritis). Cleaning surfaces like thicker carpeting necessitates a more complex, expensive appliance, but you still won’t have to spend a fortune. You can also combine the ingredients in a bucket, but you’ll have to dump out any leftovers once you’ve finished cleaning the floor. More recently, EPA has registered several new wood preservative active ingredients. He also pioneered a series of practical inventions that would make farming more profitable and less dependent on cotton, including more than 100 ways to monetize sweet potatoes, soy beans and peanuts with a conversion into dyes, plastics and fuel. Turner’s research centered on animal behavior, and he developed a series of techniques to study and measure how insects learn. For example, Turner was the first to discover insects could hear and that they were capable of changing their behavior based on previous experiences.

In 1965, he became the first African American to be inducted into the National Academy of Sciences. From 1920 to 1931 he was awarded a biology fellowship by the National Research Council. It was during this fellowship that Bath’s research uncovered some staggering statistics: When compared with her other patients, Black people were eight times more likely to develop glaucoma and twice as likely to go blind from it. She set her sights on developing a process to increase eye care for people unable to pay, now called community ophthalmology, which operates worldwide. In addition to developing crop rotation methods for sharecroppers, many of whom were former slaves, Carver designed a horse-drawn classroom to illustrate his methods firsthand. These individuals, including George Washington Carver and Mae Jemison, overcame racial and gender barriers to make groundbreaking discoveries in fields ranging from chemistry and physics to astronomy and medicine. From well-known Black scientists, such as George Washington Carver, to James West, who coinvented the microphone, to those whose impressive scientific records have nearly languished in obscurity, our list will have you rethinking what else might be left out of your history textbook.

This popular solid is a great option for anyone who wants a natural, vegan-friendly cleanser. Blue Magic is great for getting rid of tarnish and oxidation and works well on brass jewelry, the rim of a watch face, or a vintage tea set. It’s also smart-no more getting stuck under the couch-thanks to obstacle avoidance and LIDAR navigation. But, at the end of the day, most people are just looking for the best cleaning tips to help them clean faster, more effectively and less frequently. While all vacuums for carpets are designed to suck up debris, their operation style and how they collect the debris can vary. While it is generally easy to use and manoeuvre, we noted that if you lift the handle too high then the Gtech Orca will instantly turn off, which means cleaning in smaller and more confined spaces can be difficult. Keeping with the trend of agrochemical companies plunging into digital farming, Syngenta acquired FarmShots, a start-up that allows farmers to use satellite images to assess plant health. After her retirement in 1993, Bath continued to advocate for the medically underserved and focused on the use of technology to offer medical services in remote regions.
