Author & Autism Advocate #StoryTellerNotWriter Available Now: #TheCrimsonMindsTrilogy & #TheDeathBringerChronicles WIP: #TheEmeraldHoodTrilogy Having Asperger's Syndrome as well as Tourettes doesn't slow Patrick down in the slightest. His work ethic and positive attitude are infectious according to those in his life. His positivity can especially be seen in his writing; despite using heavier subjects in his books, he addresses them with a light that's rarely found in fiction these days, resulting in a profound balance of entertaining and thought provoking content that tugs at the heart strings. His various books are written in a curious, yet engaging style that is difficult to put down. Patrick's vision is to turn the idea of the traditional verse novel on it's head & to break new ground, creating something uniquely delicious, all it's own.

Rayleigh Criterion

• Diffraction limits resolution. • For a circular aperture, lens, or mirror, the Rayleigh criterion states that two images are just resolvable when the center of the diffraction pattern of one is directly over the first minimum of the diffraction pattern of the other. • This occurs for two point objects separated by the angle θ = 1.22 λ / D, where λ is the wavelength of light (or other electromagnetic radiation) and D is the diameter of the aperture, lens, mirror, etc. This equation also gives the angular spreading of a source of light having a diameter D. From http://hyperphysics.phy-astr.gsu.edu/hbase/phyopt/Raylei.html Average vision is 5 × 10⁻⁴ radians or 103.13 arcseconds or a ratio of 1:2000 [1 unit resolvable at 2000 units]
