Brain machines: A volunteer tests a brain-computer interface being developed at the University of Wisconsin. It consists of an electroencephalogram (EEG) cap that records brain activity and a device that stimulates the tongue. The position of the yellow ball on the screen is represented in electrical activity on the volunteer’s tongue. The volunteer uses brain activity (imagined movements) to move the ball to the red target. clipped from think-a-move.com

 clipped from www.nanotech-now.comScience fiction writers have long envisioned sailing a spacecraft by the optical force of the sun's light. But, the forces of sunlight are too weak to fill even the oversized sails that have been tried. Now a team led by researchers at the Yale School of Engineering & Applied Science has shown that the force of light indeed can be harnessed to drive machines — when the process is scaled to nano-proportions  clipped from www.photonics.com
Nanophotonics and nanomechanics make possible the extreme miniaturization of optics and mechanics on a silicon chip. This new research, led by scientists at the Yale School of Engineering & Applied Science, opens the door to a new class of semiconductor devices that are operated by the force of light. They envision a future where this process powers quantum information processing and sensing devices, as well as telecommunications that run at ultrahigh speed and consume little power. clipped from www.eng.yale.eduHong Tang

The river is split into two parts as it enters the Fishmouth pier, a long and narrow dike built in the shape of a fish mouth in order to receive the least water resistance. clipped from en.wikipedia.orgclipped from www.thesalmons.orgWorkers using only hand tools cut a trunk canal, called the Mouth of the Precious Jar through a towering mountain in order to feed an extensive system of canals on the plains. clipped from www.thesalmons.org

The Anlan bridge crosses the river near the upstream end of Fishmouth
Pier. It is suspended by woven bamboo cables (now reinforced with
steel). It was formerly called the Fuqi Bridge (Husband and Wife
Bridge) because it was built by a devoted couple and it is held
together by locks that symbolize the pair's never-ending devotion.

pavilions sprinkled through the forest and gardens. Erwang Temple (two
kings temple) was built as a tribute to Li Bing and his son.
The oldest tree in China dating back to the Yin Shang dynasty (1700-1100 BC)
is also in the park.

five-story high Qin Yen Lou. Mao, Deng, and Jiang Zemin have all taken
in the view from its upper platform.
