Heh and Hauhet, Deities of Infinity and Eternity
By Caroline Seawright
The ancient Egyptians [KMT] believed that before the world was formed, there was a watery mass of dark, directionless chaos. In this chaos lived the Ogdoad of Khmunu (Hermopolis), four frog gods and four snake goddesses of chaos. These deities were Nun and Naunet (water), Amun and Amaunet (invisibility), Heh and Hauhet (infinity) and Kek and Kauket (darkness).
The water stretched infinitely off in all directions, as ever lasting as time itself. Heh and Hauhet came to symbolise infinity. After time began, Heh and Hauhet came to symbolise limitless time, and long life.
The frog or human headed god Heh (Huh) was one of the original eight gods of the Ogdoad of Khmunu Continue reading

Reef on the brink
The Great Barrier Reef: a catastrophe laid bare
By Michael Slezak, 7 June 2016
Australia’s natural wonder is in mortal danger. Bleaching caused by climate change has killed almost a quarter of its coral this year and many scientists believe it could be too late for the rest. Using exclusive photographs and new data, a Guardian special report investigates how the reef has been devastated – and what can be done to save it
It was the smell that really got to diver Richard Vevers. The smell of death on the reef. “I can’t even tell you how bad I smelt after the dive – the smell of millions of rotting animals.” Continue reading
Quantum Dots: Applications for Artificial Atoms Expanding
By Lynn Savage, Feb 2011
Quantum dots, also known as semiconductor artificial atoms, have existed for several years now, and their use keeps on expanding. Primarily used as substitutes for dyes in fluorescence imaging, their propensity for being highly tunable emitters that resist photobleaching represents only a small fraction of their benefits.
Commonly but not always comprising cores of cadmium selenide with a coating of zinc sulfide, quantum dots are perhaps best known for the tunability of their emission wavelength, once excited by an external light source: Change the size of the particle, get a specific wavelength in return. Early research into the properties and potential uses for quantum dots kept them in solutions, and then later brought into proximity with a variety of other particles. This led to their nearly ubiquitous use as donors in Förster’s resonance energy transfer (FRET), a renowned method for near-diffraction-limit imaging of cells and other subjects. Continue reading
Land and Water Hemispheres, 1891
From University of South Florida
Description: A double hemisphere map of the world from 1891 showing the earth’s Land Hemisphere and Water Hemisphere.
“The accumulation of the land in the north and its separation in the south lead to a curious result — nearly all the land is collected in one hemisphere. If one point of a pair of compasses be placed at the Continue reading
1883 Eruption of Krakatoa
The 1883 eruption of Krakatoa in the Dutch East Indies (now Indonesia) began in the afternoon of August 26, 1883, and culminated with several destructive eruptions of the remaining caldera. On August 27, two-thirds of Krakatoa collapsed in a chain of titanic explosions, destroying most of the island and its surrounding archipelago.
It was one of the deadliest and most destructive volcanic events in recorded history, with at least 36,417 deaths being attributed to the eruption itself and the tsunamis it created. Significant additional effects were also felt around the world.
In the years before the 1883 eruption, seismic activity around the volcano was intense, with earthquakes felt as far away as Australia. Beginning 20 May 1883, steam venting began to occur regularly from Perboewatan, the northernmost of the island’s three cones. Continue reading
