[00:08.93]Jeffrey Chen won the Breakthrough Junior Challenge prize in science earlier this month. [00:16.94]The prize comes with $250,000 that Chen can use for college. [00:25.72]The aim of the Breakthrough Junior Challenge is to influence young people [00:31.53]so they will think creatively in science and mathematics. [00:37.58]Students ages 13-18 produce short videos [00:43.76]which explain a complex science or math subject in an interesting way. [00:51.60]The 17-year-old Chen was chosen over 14 other finalists from the United States, Canada and India. [01:03.68]The judges included several well-known scientists and educators. [01:09.80]Among them were Salman Khan, founder of Khan Academy, [01:15.40]writer Lucy Hawking and former astronaut Scott Kelly. [01:22.36]Branko Malaver-Vojvodic, 18, of Peru, won the challenge's "Popular Vote" contest. [01:31.65]He received more than 16,000 likes, shares and positive reactions for his video on cryptography. [01:42.28]You can watch it and the other videos on the Breakthrough Facebook page. [01:48.20]In his prize-winning video, on YouTube, Jeffrey Chen talks about neutrinos. [01:56.05]"This is a neutrino, you can't see or feel them, but every second each of us are bombarded with trillions of them." [02:04.40]Chen explains neutrinos are particles that are smaller than an atom. [02:12.24]He talks about how they can be used in astronomy. [02:17.08]Chen says they can help astronomers look at cosmic events. [02:23.73]"Neutrino astronomy is the next step in human discovery and who knows what we'll find next." [02:27.97]He says the small particles may provide information about the earliest days of the universe. [02:36.89]"It's definitely really incredible to have won and I have a hard time believing it," [02:45.09]Chen told San Francisco television station KGO. [02:50.32]"I'm really grateful to be in an environment that promotes science. [02:56.74]I think our school does a really good job of that." [03:02.16]Chen is in his final year at Burlingame High School. [03:06.97]He will share prizes, worth a total of $400,000, with his school and science teacher. [03:16.56]While he gets the $250,000 for college, his teacher, Heather Johnson, will receive $50,000. [03:27.60]She helped him launch an environmental science club for students. [03:33.49]His school will get a new science laboratory, valued at $100,000. [03:41.88]The competition was open to students from around the world. [03:47.08]More than 11,000 students competed in the 2019 competition. [03:54.44]There were then two rounds of judging -- the first by fellow students, [04:00.39]followed by decisions made by a group of judges. [04:05.35]The 30 semifinalists competed in the Popular Vote contest on Facebook. [04:12.50]People were invited to vote for their favorite semifinalist's work [04:17.56]by "liking," "sharing," or posting a positive reaction. [04:23.80]During the 15-day competition, the 30 videos reached more than [04:29.72]500,000 people on the Breakthrough Prize Facebook page. [04:36.27]Sal Khan, the founder of Khan Academy, partnered with the Breakthrough Prize Foundation. [04:44.20]He praised Chen's science video. [04:48.28]"Jeffery is a natural science communicator," Khan said. [04:53.16]"He artfully explains a complex topic and makes it easier to understand. [05:01.01]We're proud to support Jeffery and all the other bright minds who participated [in the contest]." [05:10.80]A California newspaper, The Daily Journal, said the competition [05:16.88]combined Chen's two great interests -- astronomy and film-making. [05:23.73]The high school senior told the paper that film-making is [05:29.08]"one of the most interesting ways to give an idea to an audience." [05:35.47]Chen also said he hopes to continue combining his interests [05:41.11]as he studies environmental technology in college. [05:46.32]He wants to work on climate change. [05:50.03]Videos made by the Breakthrough Junior Challenge finalists [05:55.20]have been added to the Khan Academy website. [05:59.64]I'm Anne Ball. 更多听力请访问51VOA.COM
