The U.S. team was finalized after an intensive two-week Chemistry Olympiad Study Camp, sponsored by the American Chemical Society and held at the U.S. Air Force Academy in Colorado Springs. The students are Steven Liu of Monta Vista High School in Cupertino, Calif.; Joshua Park of Lexington High School in Massachusetts; Harrison Wang of Hinsdale Central High School in Illinois; and Brendan Yap of Carmel High School in Indiana. Jeffrey Shi of Marcellus High School in New York is the first alternate. Aniket Dehadrai of Oklahoma School of Science and Mathematics in Oklahoma City is the second alternate. This is one of the strongest groups we have seen, says mentor Michael Danahy, a lecturer in chemistry at Bowdoin College. They came in really well prepared in all aspects of chemistry. Liu says he has been preparing for this moment for years. Last year, I was the first alternate, and it was heartbreaking, he says. Going through the cycle twice really helped me grow and improve. I think thats what helped me make the team this year. Yap says that participation in the study camp motivated him to change his intended college major from electrical engineering to chemistry or chemical engineering. … Continue reading →

Together again: Toews, Saad expect chemistry to return quickly Brandon Saad talked to plenty of people after he was traded back to the Blackhawks. Some were now ex-teammates from the Columbus Blue Jackets. Others, soon-to-be-teammates again from the Blackhawks. One of the first people he talked to on Friday? Jonathan Toews. Hes someone I talked to shortly after it happened. Hes a guy Ive always kept in touch with, great friend, Saad said. To be reunited, getting that chance to play with him again, hes an incredible player and his resume speaks for itself. I look forward to trying to rekindle that. The two didnt lose touch the past two years. Now that theyll be reunited on the ice, they hope they didnt lose the chemistry either. Saad and Toews formed a great combination a few years ago, a steadiness thats been missing from the top line, especially at left wing, ever since. With Saads return, however, the Blackhawks are looking to get that top line consistent again. [MORE: Blackhawks trade back, select Henri Jokiharju at No. 29] Toews was at the NHL Draft on Friday night, announcing the Blackhawks first-round pick with Patrick Kane. The thought of getting Saad … Continue reading →

By Emma Lockhart | Cronkite News Thursday, June 22, 2017 WASHINGTON You might not know which chemical element in the Hope Diamond has the largest molecular mass, but an eighth-grader from Scottsdale does. Isaiah Hazelwood faced that and other questions faced earlier this week when he squared off against other middle school students from around the country as part of the You be the Chemist National Challenge in Washington. The lanky 13-year-old whos in the eighth grade at Basis Scottsdale won the state competition in February to advance to the nationals on Monday, competing against 41 other students representing 39 states, Puerto Rico and the District of Columbia. The competition drew a total of 55,000 students at the local and state levels, according to a prepared statement from Dwayne Sattler, executive director of the Chemical Education Foundation, which sponsored the contest. Students like Isaiah, who are excited about particular subject areas, certainly dive a little bit deeper and our teachers help work with them to foster that excitement, Basis Scottsdale Principal Kristen Jordison said by phone this week. Between rounds, Isaiah spoke quietly and looked away during interviews until the conversation turned to chemistry. Then, he lit up. Im excited … Continue reading →

As for Wang herself, she said she genuinely enjoyed working in the sciences, but still felt her fate lay elsewhere. I like research, but I realized that someone else could be doing that research, with my writing I felt like I could be the only one doing that, she said. In addition to the books humor, reviewers have noted Wangs choice to keep her narrator nameless. Wang explained that the decision to do so was a deliberate one. When I think of a name it is very specific to the character and I didnt want that to happen, Wang said. Would I name her something Chinese or something American? I didnt want to deal with that. Juggling multiple identities is something Wang has a bit of experience in. Born in China, she and her family moved to Australia when she was 7 and later moved to Canada and then eventually to the United States. When I write characters that are not open, its because Im not necessarily that open in terms of opening up to new people, Wang said. I made her like that in that she is just very lonely. And when you are lonely, you are not used … Continue reading →

STEM and VR MEL Science, based in London, has launched a series of virtual reality (VR) chemistry lessons for K12. The 3-year-old company this week released a MEL Chemistry VR app, featuring a virtual chemistry lab, for free on Google Daydream. This free version, which contains the first six chemistry lessons, is available at this MEL Science site. According to MEL Science, chemistry is filled with abstract concepts that may prove difficult for young students to understand. The best method for kids to learn is through hands-on interaction, so MEL Science developed these VR chemistry lessons to enliven molecular-level science and illustrate it on an immersive, life-sized level. The lessons follow K12 curricular guidelines, and are designed to be used in the classroom or at home. A special version for educators will be released soon, the company said. In these first six lessons, students should be able to see what its like to dive into a pencil (graphite) or a diamond and discover what these objects look like on an atomic level. Students should be able to learn about basic chemistry principles in an interactive, friendly way, including topics such as: Students will also get the opportunity to build an … Continue reading →

[+]Enlarge DuPont has developed ionomeric resins for making balls that fly farther. Credit: DuPont Manufacturers have taken a fresh swing at the chemistry of golf balls in recent years to make balls that suit every golfer, from the duffers that shank them out of bounds to the latest hot shots who bend them around bunkers on the pro tour. Much of the latest chemistry is designed to make balls that are more controllable or fly fartheror both. Softer balls typically give golfers better control, while harder balls travel faster. The latest golf ball brand names (Max, Rush, TruSpeed, and Velocity) hint at where the technology is headed. About 1.2 billion golf balls are produced every year. There are more than 80 different types of balls of varying construction materials and designs. Although major changes have taken place in ball formulation recently, golf ball technology has been on an upswing for more than 500 years; that is, ever since the game was invented on the eastern coast of Scotland sometime in the 15th century. Back in the day, golfers played with wooden clubs and made their balls from local hardwoods such as beech. In 1618, golf ball technology really began to … Continue reading →

Jamie Fisher, The Washington Post Chemistry Chemistry Book World: Weike Wang's 'Chemistry' charts a young woman's toxic reaction to stress Chemistry By Weike Wang Knopf. 211 pp. $24.95 --- Weike Wang's "Chemistry" is the most assured novel about indecisiveness you'll ever read. Consider its opening lines: "The boy asks the girl a question. It is a question of marriage. Ask me again tomorrow, she says, and he says, That's not how this works." The boy is Eric; the girl, our narrator, goes unnamed. Both are graduate students in chemistry: He has just graduated; she has one year left. They have been together for four years, and their relationship has reached the point where whenever she invites friends over for dinner, they assume she will announce her engagement. But when Eric really does propose, she hovers, uncertain and unnerved. Eric is cheerful, capable, from small-town Maryland. (The narrator wonders "why he left a place where every ice-cream shop is called a creamery to work seventy-hour weeks in lab.") Their relationship is bashful and enormously endearing. He compliments her vials. When he gets the job offer he's been hoping for, he puts a doily on her head and dances her around the … Continue reading →
