Here’s how it works, step by step:
The transmitter chip is made of four hybrid silicon lasers.
Light beams from the lasers each travel into an optical modulator.
The modulator encodes data onto the beams at 12.5Gbps.
The four beams are then combined and output to a single optical fiber, for a total data rate of 50Gbps.
At the other end of the link, the receiver chip separates the four optical beams and directs them into photo detectors.
The photo detectors convert data back into electrical signals.

Sydney has become a beacon that brings people together and sparks conversations. Most recently the conversation centred on the topic of girls in tech and what might be done to re-dress the gender balance in STEAM subjects and related career pathways. Sponsored by INTEL this Vivid Ideas event drew a mix of entrepreneurs, educators and tech luminaries to the Museum of Contemporary Art on a Saturday afternoon to share their ideas on what might be done.
Wendy Hawkins: Let them be scientists - 20 views

The key to inspiring children to pursue science can be found in the curious and inquisitive spirit we all tap into as we first discover the world. Wendy Hawkins demonstrates why we need to inject a more experimental approach into our science curriculum to ensure that we stay connected to the scientist in all of us.
Idaho Teachers Fight a Reliance on Computers - NYTimes.com - 32 views

Last year, the state legislature overwhelmingly passed a law that requires all high school students to take some online classes to graduate, and that the students and their teachers be given laptops or tablets. The idea was to establish Idaho’s schools as a high-tech vanguard. To help pay for these programs, the state may have to shift tens of millions of dollars away from salaries for teachers and administrators. And the plan envisions a fundamental change in the role of teachers, making them less a lecturer at the front of the room and more of a guide helping students through lessons delivered on computers.

“Teachers don’t object to the use of technology,” said Sabrina Laine, vice president of the American Institutes for Research, which has studied the views of the nation’s teachers using grants from organizations like the Gates and Ford Foundations. “They object to being given a resource with strings attached, and without the needed support to use it effectively to improve student learning.”

What a pity, a sign of how little respect people actually give to the profession of teaching; the only profession where people don't take the comments of practitioners seriously. Can you imagine saying to your doctor, "I know this is your diagnosis, but I'm going to go with my Great Aunt's diagnosis."
