This impressive photo by Keri Lee Nelson shows us a mushroom-shaped iceberg. Part of a larger iceberg that's slowly shedding weight via calving, as it loses weight the smooth part (which has been submerged for some time) is rising out the water [source: buff.ly/2QLLvRd] Image
This mushroom iceberg was observed in 1912 by Frank Hurley, who visited Antarctica as a member of the First Australasian Antarctic Expedition, 1911-1914 [source: buff.ly/3jDM9wI] Image
Sometimes mushroom-shaped icebergs can look like something else. This is an iceberg shaped like a dragon, towering ~ 15 feet above the waters of Muir Inlet, Glacier Bay National Park, Alaska [source: buff.ly/2EUK7cj] Image

This animation shows the different effects produced by an earthquake on the conventional and anti seismic foundation of a building [source, Said Lopez: buff.ly/3nPrt7j]
Anti-seismic fondation can use several kinds of dampeners. This is a bi-directional dynamic loading test on steel damper for base isolated buildings simulating the behavior caused by earthquake [source, full video, Tokyo Tech: buff.ly/3mV1cDo]
Another kind of anti-seismic foundation is obtained using pendulum bearings that consist of an upper/lower spherical plate with sliding surface applied with special coating and a moving disc [source, full video, magebagroup: buff.ly/2L1BOhO]

There is, however, a different approach to mind uploading that uses a completely different set of technologies: mind virtualisation, i.e. extracting a number of characteristics from a mind to develop a model that can be used to simulate future behaviour buff.ly/2KdpXg4
