Approx 10,200 BC - 2000 BC).Direct evidence for the existence of tattoos exists only as far as 4000 years in history.Earliest tattoed human body is that of Ötzi the iceman who lived between 3370 and 3100 BC and was found in the Ötztal Alps between Austria and Italy.

Vacuum CleanerA vacuum cleaner, also known as a sweeper or hoover, is a device that uses an air pump to create a partial vacuum to suck up dust and dirt, usually from floors, and from other surfaces. Basically, it is a device which sucks your home tidy.Timeline2300 B.C. - First rudimentary forms of broom and cleaning tools came into existence1797 - Levi Dickenson devised a broom with the use of sorghum bristles. The sorghum broom business exploded and by 1860 sorghum got the name broomcorn.1858 - Hiram Herrick patented a carpet sweeper which was the first American patent for a carpet sweeper. The device consisted of a rolling broom and dustpan.1860 - Daniel Hess produced a carpet sweeper which used suction through a rotating brush and bellows. It was completely manual and that is probably the reason why it was not successful. It was the first rudimentary design of a vacuum cleaner.1869 - Ives W. McCaffe came up with ‘Whirlwind’, the first manual vacuum cleaner which was upright. The belt driven, hand-powered

Birth control is a method or a device that is used to prevent pregnancy. Though safe and effective birth control came into existence only in the 20th century, ways to prevent pregnancy have been devised since ancient times. Birth control has been the centre of many controversies as well.For pregnancy to occur, sperm must flow up the vagina, through the cervical opening into uterus into one of the fallopian tubes. If an egg is present in the tube, one sperm could fertilise it. Contraceptives either block the sperm kills it before it reaches uterus or prevents ovulation.History of birth controlCave paintings from 15,000 years ago in France apparently depicted condoms.Ebers Papyrus, an Egyptian medical papyrus from around 1550 BC and Kahun Papyrus from 1850 BC have documented some form of birth control from the ancient Egyptian times. These used honey, acacia leaves etc to be placed in the vagina to block sperm.Chinese used Mercury and Lead cocktail that lead to sterility, brain damage, kidney failure and death.

Continental DriftThe idea first put forward by Abraham Ortelius in 1596 and also by Francis Bacon in 1620 mostly due to the apparent similarities in the outlines of the continents. This was the period when maps were surfacing and gave a clearer view of continents.Alfred Wegener further developed it in 1912. Stated the continents are moving away from poles due to the bulge towards the equator. Though these forces exist, they are too weak to push the continental plates.Wagner suggested that continents once were together and then they started moving apart.Supercontinent was called Pangaea which meant entire Earth during the Permian period around 240 million years ago.Tharp-Hezeen MapIn 1977, Marie Tharp and Bruce Hazeen along with artist Heinrich Berann produced the first World Ocean Floor Panorama.Tharp worked out of Lamont Geological Observatory at Columbia University.Started using sonar pings to gather data from ocean floor since 1952 to map the ocean floor.Discovered the rift valley down the centre of Atlant

The Blockchain FundaAccording to Hubspot research, one of the most confusing emerging technology.Blockchain is a digital method of economic transaction record-keeping – also known as a ledger.Security keeps it differentiated from other technologies. Records are kept open within a network but no one can edit or delete.It is like a database that can be updated only through solving a complex mathematical problem.The chain is linked through hash from the previous block and the chain continues to the hash from the genesis block which happens to be the first block in the entire chain.Designed to be resistant to modification especially backdating or other tampering with the timestamps and other details in a financial transaction.Latest fad in the tech industry.Described back in 1991 to timestamp digital documents.Used in 2008 by Satoshi Nakamoto to create cryptocurrency called Bitcoin.Each block contains data, hash of the block and the hash of the previous block.Bitcoin:On 9 Jan, 2009, Satoshi Nakamoto announced the
