About This Design

Venus and Earth Orbits Per Martineau Card

Venus and Earth Orbits Per Martineau Card

This image was inspired by the remarkable work of John Martineau, in "A Little Book of Coincidence". The orbital relationship between Earth and Venus is described by two concentric circles. The inner circle represents the orbit of Venus which passes through the centres of 8 circles that just touch each other. The outer circle represents the orbit of Earth which touches the outer sides of these 8 circles. The accuracy of this relationship is 99.99% ! More info: http://www.GeometryCode.com. Tiled colourized planes of the magma of Venus (shifted in 90 degree increments of hue) form the background. Spheres are used to represent the circles for artistic effect, and the outermost eight spheres are decorative only. I think John Martineau's name will (some day, hopefully soon!) be heralded among Kepler, Galileo, Newton and Einstein for the astronomical discoveries he's made. Here's a link to John's book if you haven't seen it (HIGHLY recommended): http://www.amazon.com/exec/obidos/ASIN/0802713882/intent-20 (Created with POV-Ray http://www.povray.org)

This card was so lovely and my granddaughter opened the card and hugged it as it had a unicorn on the front and her name And I added a picture inside of us And when her mummy Asked her who it was from she said my nanny and grandad and hugged the card she can’t read yet but knew who it was from. ❤️. Excellent quality of printing colour

We downloaded several photos which was simple and produced a very attractive personalised card for our 11yr old Granddaughter. I was concerned that the card would not arrive on time but Zazzle came up trumps and the card arrived on the day before her birthday - perfect! I didn't see the card as it went straight to our family in New Zealand. However they did send a photo and it looked excellent!
