Robert Andrews Millikan
Robert Andrews Millikan ( ; March 22, 1868 – December 19, 1953) was an American physicist who received the Nobel Prize in Physics in 1923 "for his work on the elementary charge of electricity and on the photoelectric effect". Millikan graduated from Oberlin College in 1891 and obtained his doctorate at Columbia University in 1895. In 1896, he became an assistant at the University of Chicago, where he became a full professor in 1910. In 1909, Millikan began a series of experiments to determine the electric charge carried by a single electron. He began by measuring the course of charged water droplets in an electric field. The results suggested that the charge on the droplets is a multiple of the elementary electric charge, but the experiment was not accurate enough to be convincing. He obtained more precise results in 1910 with his Oil drop experiment, oil-drop experiment in which he replaced water (which tended to evaporate too quickly) with oil. In 1914 Millikan took up wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ancient Apocalypse
''Ancient Apocalypse'' is a Netflix series, where the British writer Graham Hancock presents his pseudoarchaeological theory that there was an advanced civilization during the last ice age and that it was destroyed as a result of meteor impacts around 12,000 years ago. He argues that the survivors passed on their knowledge to hunter-gatherers around the world, giving rise to all earliest known civilizations. The episodes feature Hancock visiting archaeological sites and natural features which he claims show evidence of this. He repeatedly alleges that archaeologists are ignoring or covering up the evidence. Archaeologists and other experts say that the series presents pseudoscientific claims that lack evidence, cherry picks, and fails to present the counter-evidence. The documentary was also criticised for delegitimising the achievements of Indigenous peoples. Some non-academic reviewers also found the theories unconvincing and criticized Hancock's complaints about 'mainstr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graham Hancock
Graham Bruce Hancock (born 2 August 1950) is a British journalist and author who promotes pseudoscientific ideas about ancient civilizations and hypothetical lost lands. Hancock proposes that an advanced civilization with spiritual technology existed during the last Ice Age until it was destroyed following comet impacts around 12,900 years ago at the onset of the Younger Dryas. He speculates that survivors of this cataclysm passed on their knowledge to primitive hunter-gatherers around the world, giving rise to all the earliest known civilizations (such as ancient Egypt, Sumer, and Mesoamerica). Born in Edinburgh, Hancock studied sociology at Durham University before working as a journalist, writing for a number of British newspapers and magazines. His first three books dealt with international development, including ''Lords of Poverty'' (1989), a well-received critique of corruption in the aid system. Beginning with '' The Sign and the Seal'' in 1992, he shifted focus to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Younger Dryas Impact Hypothesis
The Younger Dryas impact hypothesis (YDIH) proposes that the onset of the Younger Dryas (YD) cool period (stadial) at the end of the Last Glacial Period, around 12,900 years ago was the result of some kind of cosmic event with specific details varying between publications. The hypothesis is widely rejected by relevant experts. It is influenced by creationism, and has been compared to cold fusion by its critics due to the lack of reproducibility of results. It is an alternative to the long-standing and widely accepted explanation that the Younger Dryas was caused by a significant reduction in, or shutdown of the Shutdown of thermohaline circulation, North Atlantic Conveyor due to a sudden influx of freshwater from Lake Agassiz and deglaciation in North America.: "The prevailing hypothesis is that the cooling and stratification of the North Atlantic Ocean were a consequence of massive ice sheet discharge of meltwater and icebergs and resulted in reduction or cessation of the North Atl ...
