Dome of the Pantheon

The domed ceiling of the Pantheon in Rome is an incredible structure that has stood the test of time. Completed around 126AD, almost two thousand years after it was built, the Pantheon’s dome is still the world’s largest unreinforced concrete dome. The height to the oculus  and the diameter of the interior circle are the same, 142 feet (43 m).

Weekly Photo Challenge : Satisfaction

When an image comes out well, it gives me satisfaction, even if it comes from using some clever technology like Prisma. This is a shot of the fountain in Tavisuplebis Moedani (Liberty Square) in Tbilisi. The image was put through the Prisma “electric” filter on my android phone, which uses some clever AI, I felt satisfied with the result.

Inside Prometheus Cave

Any material which is soluble, can be deposited as a colloid or is in suspension, or is capable of being melted, may form a stalactite. Calcium Bicarbonate solution travels through the rock until it reaches an edge and if this is on the roof of a cave it will drip down. Over time a stalactite will form. An average growth rate is 0.13 mm (0.0051 inches) a year, so these speleothems mark a long passing of time.
