Girls in Tech - Reflections from VIVID Ideas - The Learner's Way - 11 views

  •  
    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.

    Funded by the Australia Government a great way for students to explore and research the ethics of current science and technology issues.

    Check out the resources section for a link where you can find resources aligned to the Australian National Science Curriculum. There is some great stuff there if you have a good dig around.

Scientists make quantum breakthrough - 25 views

  • Scientists have demonstrated for the first time that atoms can be guided in a laser beam and possess the same properties as light guided in an optical communications fiber.
  • Abstract Speckle patterns produced by multiple independent light sources are a manifestation of the coherence of the light field. Second-order correlations exhibited in phenomena such as photon bunching, termed the Hanbury Brown–Twiss effect, are a measure of quantum coherence. Here we observe for the first time atomic speckle produced by atoms transmitted through an optical waveguide, and link this to second-order correlations of the atomic arrival times. We show that multimode matter-wave guiding, which is directly analogous to multimode light guiding in optical fibres, produces a speckled transverse intensity pattern and atom bunching, whereas single-mode guiding of atoms that are output-coupled from a Bose–Einstein condensate yields a smooth intensity profile and a second-order correlation value of unity. Both first- and second-order coherence are important for applications requiring a fully coherent atomic source, such as squeezed-atom interferometry.
