The award
The Society for Science lists Kleinwort among the 2014 top winners with a $50,000 Intel Foundation Young Scientist Award, one of two given beneath the fair's $75,000 first prize. His project is described as dynamic mathematics on smartphones and tablets.
At 15 he was the same age as that year's overall winner, Nathan Han of Boston. Two of the three 2014 top awards went to fifteen-year-olds, which is unusual in a competition whose finalists skew toward the final years of secondary school.
What dynamic mathematics means
Dynamic mathematics software is the category of tools in which a construction can be manipulated and the mathematics updates live: drag a point and the triangle, the graph and the calculated values all move with it. It has been standard on desktop computers in mathematics classrooms for decades.
The contribution named in the listing is the platform. Moving that interaction onto a phone or tablet means rebuilding it for a touch screen and a small display, where the mouse-driven conventions of desktop geometry software do not transfer. The source gives no further description, so no claim is made here about how the software worked or whether it was released.
The 2014 fair
Intel ISEF 2014 ran from 11 to 16 May at the Los Angeles Convention Center, with more than 1,700 young scientists selected from 435 affiliated fairs in more than 70 countries, regions and territories.
More than 500 finalists received awards, including 17 Best of Category winners at $5,000 each, and the Intel Foundation gave $1,000 grants to each winner's school and affiliated fair. Germany participates through its own national science competition network, which feeds the international fair.
The other 2014 winners
The Gordon E. Moore Award of $75,000 went to Nathan Han, 15, of Boston, for 'Characteristics of Deleterious Mutations in Tumor Suppressor Genes'.
The second $50,000 award went to Shannon Winjing Lee, 17, of Singapore, for nature-derived carbon microsheets used as an efficient electrocatalyst for energy storage. Educational software, cancer genetics and energy materials shared the top of the 2014 standings.
What is documented — and what is not
The listing gives his name, age, home city and the award, with a one-line description of the project. It names no school, no mentor and no company, and it does not say whether the software was published or distributed.
It also stops at the fair. No source used here reports his later studies or work, and his birth year is inferred from being 15 in May 2014. Anything beyond that is outside the record used for this page.
Software as a science fair entry
Educational software sits awkwardly in a competition built around experimental research: there is no hypothesis to test in the conventional sense, and the value of the work is in whether people can use it.
That a software tool took one of the three top awards says something about how the fair's judging works. Projects are assessed on originality, technical execution and usefulness, not only on laboratory method, which is what allows a fifteen-year-old's application to be ranked alongside cancer genetics.
