The history of videotelephony<\/strong> covers the historical development of several technologies which enable the use of live video<\/a> in addition to voice telecommunications<\/a>. The concept of videotelephony was first popularized in the late 1870s in both the United States and Europe, although the basic sciences to permit its very earliest trials would take nearly a half century to be discovered. This was first embodied in the device which came to be known as the video telephone, or videophone, and it evolved from intensive research and experimentation in several telecommunication fields, notably electrical telegraphy<\/a>, telephony<\/a>, radio<\/a>, and television<\/a>.<\/p>\n\n\n\n

In December 1631, Mount Vesuvius<\/a> in Italy<\/a> erupted. The eruption began on 16 December 1631 and culminated the day after.[1]<\/a><\/sup> The Volcanic Explosivity Index<\/a> was VEI-5, and it was a Plinian eruption<\/a> that buried many villages under the resulting lava flows<\/a>.[2]<\/a><\/sup> It is estimated that between 3000 and 6000 people were killed by the eruption, making it the highest death toll for a volcanic disaster in the Mediterranean<\/a> in the last 1800 years.[citation needed<\/a><\/em>]<\/sup> The 1631 eruption was considered to be of minor proportions regarding its eruptive magnitude and erupted volumes compared to the AD 79 eruption<\/a>, but the damage was not.[citation needed<\/a><\/em>]<\/sup> By the 1631 eruption, the summit of Mount Vesuvius had been reduced by 450m, making its total height lower than that of Mount Somma<\/a>.[3]<\/a><\/sup><\/p>\n\n\n\n

    Healing Crystals: What They Can and Can\u2019t Do<\/h2>\n\n\n\n

    Two researchers, the brothers Pierre and Jack Curie, conducted a study<\/a> in 1880 and found that changing the temperature of crystals and putting pressure on them could create electricity.<\/p>\n\n\n\n
