Scientists in Sweden say they have confirmed a new, super-heavy element that was first proposed by Russian scientists in 2004. The element with the atomic number 115 has yet to be named.
In a press release, Lund University says a group of international scientists led by physicists from Lund University, made the element by shooting a beam of calcium, which has 20 protons, into a thin film of americium, which has 95 protons.
For less than a second, the new element had 115 protons.
Technicians on Saturday are set to cast 20 tons of glass for the third of seven ultra-precise primary mirrors that will make up the 72-foot Giant Magellan Telescope, scheduled for completion in northern Chile's arid Atacama Desert in 2020.
The parabolic mirror will be cast at the University of Arizona's Steward Observatory Mirror Lab. The molten borosilicate, made by the Ohara Corporation, will be spun cast at 2140 degrees Fahrenheit.
There's a joke among scientists: Prediction is difficult, especially about the future. For Ross Stein, it wasn't a joke after the Indian Ocean quake and tsunami in 2004. It killed some 275,000 people. "I just felt almost a sense of shame," Stein says, "that this tragedy could have been so immense in a world where we have so much intense research effort."
"If you could imagine a grandfather clock and see the pendulum swinging back and forth, ideally that pendulum would swing back and forth very uniformly," Ludlow says. "Each swing would take exactly the same amount of time."
That's stability. But what if something perturbs the system, like a mischievous toddler?
