    Featured above is a 3-D view ( stereograph) of 2 and a half turns of
    the DNA molecule. I put together this 3-D model from a
    Cochranes of Oxford kit, and Dr. Brian May created the
    stereograph – in mid-December of 2022. A DNA molecule consists of two
    long polynucleotide strands or chains made up of four types of
    nucleotide subunits. Each such molecule contains the biological
    information responsible for making every species unique.

    You can view the stereograph by:
    1. Using the Cross-Eyed method
    2. Using 3D prism glasses
    3. Using B rian May’s OWL Stereoscope

    Light Rings Illusion

    To be able to see the circle like features in the tree canopy shown
    above, the solar elevation and my angle of incidence had to be just
    right. Branches and twigs that are roughly perpendicular to the Sun act
    as mirrors of sorts, scattering light back towards the viewer. It’s
    our pattern-seeking brains that merge the individual glints into
    circles. Photo taken on January 4, 2023.

    Photo details: ISO 200;1/250 second exposure; f6.3.
