Ten people who mattered this year. Nature YUAN CAO: Graphene wrangler A PhD student coaxed superconductivity from sheets of atom-thick carbon. BY ELIZABETH GIBNEY Credit: Corinna Kern for Nature Yuan Cao’s teenage years were hardly typical. By age 18, he had already graduated from high school, completed an undergraduate degree at the University of Science and Technology of China in Hefei, and travelled to the United States to begin his PhD. He hasn’t slowed down since: this year, aged just 21, Cao had two papers published on strange behaviour inRead More

Mike Lovett Samia Tamazi ’20 PAGE 2 OF 3 In 2006, Epstein won a four-year $1 million grant from the Howard Hughes Medical Institute to develop a Posse program specifically for students from the New York City area interested in the sciences. (The grant was renewed in 2010.) Associate professor of biology Melissa Kosinski-Collins, who has published widely on science education, believed incoming Science Posse students needed exposure to college-level science before the chaos of Orientation in late August and the transition to a full schedule of college classes.

Foucault’s Pendulum at Museu de les Ciències Príncipe Felipe in Valencia (Spain). Photo: Manuel M. Vicente/Wikimedia Commons ONCE UPON A time, you were probably on an elementary school field trip at a science museum or an observatory. Just before lunch, your teacher had the class stand in a circle around an enormous weight suspended on a string, and watch it swing back and forth, back and forth. The teacher (or maybe a tour guide) explained that if you watched the pendulum for long enough, it would seem to alter itsRead More

Transistors   by Chris Woodford. Last updated: September 9, 2016. Your brain contains around 100 billion cells called neurons—the tiny switches that let you think and remember things. Computers contain billions of miniature “brain cells” as well. They’re called transistors and they’re made from silicon, a chemical element commonly found in sand. Transistors have revolutionized electronics since they were first invented over half a century ago by John Bardeen, Walter Brattain, and William Shockley. But what are they—and how do they work? Photo: An insect with three legs? No, a typical transistor onRead More

The Nobel Prize in Physics 2000-Jack S. Kilby – Biographical Zhores Alferov, Herbert Kroemer, Jack Kilby The Nobel Committee has asked me to discuss my life story, so I guess I should begin at the beginning. I was born in 1923 in Great Bend, Kansas, which got its name because the town was built at the spot where the Arkansas River bends in the middle of the state. I grew up among the industrious descendents of the western settlers of the American Great Plains. My father ran a small electricRead More

Integrated circuits by Chris Woodford. Last updated: April 18, 2016. Have you ever heard of a 1940s computer called the ENIAC? It was about the same length and weight as three to four double-decker buses and contained 18,000 buzzing electronic switches known as vacuum tubes. Despite its gargantuan size, it was thousands of times less powerful than a modern laptop—a machine about 100 times smaller. If the history of computing sounds like a magic trick—squeezing more and more power into less and less space—it is! What made it possible was the invention ofRead More

DDoS & IoT – A ‘Perfect’ Storm OCT 28, 2016  Author: Angus Macrae A perfect storm is definitely brewing. Severe and hazardous internet weather warnings have been out there for some time now, and last week’s DDoS downpour on Dyn, along with the escalating events leading up to it, may prove to be a mere shower compared to what is yet to come. Let’s start by considering another type of forecast, that of the projected numbers for theInternet of Things (IoT). We are currently told there will be 20 billion ‘things’Read More

BY RICK HODGIN 07.09.2009 :: 3:40PM EDT Recently, Intel has published a page showing the step-by-step process of how a CPU is made. From sand to its final product, there are many complex steps involved. In fact, it’s absolutely amazing that semiconductor products work at all. Step 1 – Sand At about 25% (by mass), silicon is the second most frequent chemical in the earth’s crust (behind oxygen). Sand has a high percentage of Silicon Dioxide (SiO2), which is the base ingredient for semiconductor manufacturing. Step 2 – Melted Silicon SiliconRead More

The point of Minecraft seems simple: build practically anything you can imagine. Some kids recreate famous pieces of architecture, others express their creativity through grand designs. Since 2009, Minecraft has sold over 20 million copies. And if that seems like a typical blockbuster, don’t be fooled — it isn’t. Graphics are boxy and blurry, and sounds are primitive at best. So why do kids obsess over it? I gather a handful of 5-to-13-year-olds. I want to know why they love about it and what they get out of it. I expect simpleRead More
