An American engineer has produced a mathematical model explaining the elegant shape of the Eiffel Tower that was derived from French engineer Gustave Eiffels writings regarding his own fears about the effects of wind on such a structure.
University of Colorado at Boulder Associate Professor Patrick Weidman said Eiffel, one of the premier structural engineers in history, was determined to build the worlds first tower reaching 300 meters, the nearest metric equivalent to 1,000 feet, into the sky. The tower was designed to be the centerpiece of the Worlds Exposition in Paris, marking the centennial of the French Revolution.
But such a tower, never having been successfully erected, raised a chronic concern of Eiffel that he expressed frequently in his communications. "Eiffel was worried about the wind throughout his building career," said Weidman of the CU-Boulder mechanical engineering department. "Although he was astoundingly bright, he was forced to rely on practical experience rather than mathematical calculations to estimate the effects of wind forces on structures."

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
