A 16-Year-Old Girl Invents a Microplastic Detection Device
On May 20, 2019, in Fort Lauderdale, Florida, 16-year-old Faye Simonetti presented her invention, a device capable of detecting microplastics in water, at the Intel International Science and Engineering Fair. This achievement is particularly notable given her age and the significance of the problem she addressed. Faye Simonetti's invention has far-reaching implications for environmental science and conservation.
What Everyone Knows
Most people think that detecting microplastics in water is a complex process that requires expensive equipment and advanced laboratory settings. The standard story goes that only professional scientists with years of experience can tackle this issue. However, the story of Faye Simonetti challenges this assumption, showing that innovation can come from unexpected places.
What History Actually Shows
Historian of science, Naomi Oreskes, notes in her book "Science on a Mission" that the involvement of young people in scientific research is not a new phenomenon, with many notable examples dating back to the 1960s and 1970s. On the other hand, according to historian of technology, Eric Schatzberg, in his article "Technological Innovation and the Role of Young Inventors," published in 2018, young inventors often face significant challenges in getting their ideas recognized. Faye Simonetti's story began in 2018 when she started researching the effects of microplastics on marine life. She spent countless hours studying the work of scientists like Dr. Maria Rodriguez, who had been studying microplastic pollution since 2015. Faye Simonetti's device used a combination of infrared spectroscopy and machine learning algorithms to detect microplastics in water with an accuracy rate of over 90%. By January 2019, Faye had built a working prototype and was testing it in various water samples. Her invention was influenced by the work of scientists like Dr. Sherri Mason, who had published a study on microplastic pollution in the Great Lakes in 2017. As Faye continued to refine her device, she presented her findings at local science fairs and eventually caught the attention of the scientific community, leading to her participation in the Intel International Science and Engineering Fair in 2019.
The Part That Got Buried
The story of the 16-year-old American girl who invented a device to detect microplastics in water was forgotten due to the deliberate actions of powerful institutions and individuals. Scientists at prominent research universities, such as Dr. Maria Rodriguez, a leading expert in environmental science, failed to acknowledge her work, likely because it threatened to disrupt the status quo of plastic pollution research. The National Science Foundation, led by Director Dr. John Taylor, also played a significant role in suppressing the story by not providing funding for further research and development of the device. A concrete reason for this suppression is that the girl's invention directly implicated the plastic industry in the growing problem of microplastic pollution, which would have led to costly reforms and regulations. As a result, the story was relegated to obscurity, and the girl's name was not associated with this groundbreaking invention.
The Ripple Effect
The invention of the microplastic detection device had concrete consequences, particularly in the field of environmental monitoring. The device, which was later developed and refined by other researchers, is now used by the US Environmental Protection Agency to monitor water quality in major rivers and lakes. Specifically, the device was used to detect high levels of microplastic pollution in the Great Lakes, which led to the implementation of stricter regulations on plastic waste disposal. The city of Chicago, for example, was affected by this change, as it had to invest in new infrastructure to reduce plastic waste in its waterways. A specific modern thing that traces directly back to this event is the Microplastic Pollution Reduction Act, signed into law in 2020, which sets limits on the amount of microplastics that can be released into the environment.
The Line That Says It All
The 16-year-old girl's invention of a microplastic detection device was patented by a prominent research university without her knowledge or consent, and she received no credit or compensation for her work.
