      Obsidian blades are still being used, relatively, regularly to this day.


      Obsidian is a naturally occurring type of volcanic glass, that is extremely hard and brittle. It therefore fractures with very sharp edges, which were used in the past in cutting and piercing tools, it has even been used experimentally as surgical scalpel blades.


      These blades are spectacularly sharp and smooth, being so sharp they are capable of cutting through individual cells. In comparison to steel scalpels which under a high power microscope appear more like saws than scalpels.


      The obsidian edge when, cut correctly, is so sharp that it’s edge is 30 angstroms in width, a unit of measurement equal to one hundred millionth of a centimetre, that’s over 16.6 thousand times thinner than a human hair.


      Their use however is limited due to their fragility, the blades are so thin that one miniscule move from side to side can shatter it, a problem steel scalpels do not have, needless to say a shard of volcanic glass being stuck in the patient is not a good thing.


      Thus it takes a great deal of practice to be able to use these blades effectively with minimum risk, though this practice can pay off as it has been found that obsidian scalpels may reduce inflammation, healing time and scarring in the patient due to the lessened irritation caused by the blade.


      Ultimately however the blades cannot be justified for use outside of very fine surgery, due to their higher cost from being hand made, their greater fragility and their little forgiveness for wayward movements.


      So much so that the FDA has not approved them for use, despite the benefits they can bring, thanks to the higher tolerance they must be held in and their extreme fragility.



      Huh...

      I wonder if trepanning will make a comeback in western medicine as well?

      If you think parrots are good at mimicking sound then you have yet to meet the Lyrebird.


      The lyrebird is either of two species of ground-dwelling Australian birds. They are most notable for their outstanding ability to mimic natural and artificial sounds from their environment


      The song of the superb lyrebird is a mixture of elements of its own song and any number of other mimicked songs and noises. This could be any other birds songs, the sound of rustling leaves, a car driving past or even a person talking.



      I am now afraid of what this bird could order in my name...

      The well known and loved Beatles song "Being For The Benefit of Mr. Kite!" was inspired by a 1843 circus poster for Pablo Fanque's Circus Royal appearance at Rochdale.


      Lennon purchased the poster in an antique shop on 31 January 1967, while filming the promotional video of "Strawberry Fields Forever" and "Penny Lane".


      The poster showed all of the events and performances mentioned in the song: Henderson, a wire-walker, equestriantrampoline artist, clown, hogshead and the eponymous Mr. Kite, a Mr. William Kite to be precise. 


      So there you are, one of The Beatles most famous songs was based on a poster that John Lennon thought looked cool.

      I decided to take a little over a week off from posting any FoTD's as I have been rather busy as of late, with my paternal grandmother's death and ensuing funeral. So I took some time off to decompress and not have to worry about putting something up everyday.


      Though I'm feeling more up to it now so you can expect an FoTD today.

      In one study researchers tried 2,000 times to ignite gasoline with a cigarette and failed.


      In fact gasoline, in its liquid form, will even put a cigarette out.


      Action movie heroes are gonna need a new schtick.

      The word RADAR is actually an abbreviation.

      The first example of radio technology being used to provide advance warning to airmen was by, Scottish radio physicist, Robert Watson, in 1915. 

      At which time the technique was simply called radio direction finding.


      The term RADAR was not coined until 1940, by the United States Navy, as an acronym for RAdio Detection And Ranging or RAdio Direction And Ranging.


      It’s impressive the number little known, but hugely impactful, Scottish inventors and scientists there are.

       The Reichstag, the German parliament building, has a glass dome above it that the public can climb using a spiral ramp. The dome symbolises that the people are above the government and the government should be transparent.


      I've been to this building, the dome is beautifully designed, you can see directly into the main hall, wherein the government does its work.

      Moriusaq, Greenland, had an effective population of 3 inhabitants in 2009. A case of self-defence dropped the population to 2.


      Well, here's hoping it was a guy and girl, because they are gonna need to start repopulating.

      The first species name ever given to an extinct species of dinosaur was "Scrotum Humanum".

      Yes, that scrotum.


      Possibly the first dinosaur, apart from modern birds, to be described in scientific literature was the Megalosaurus.


      Part of a bone was recovered from a limestone quarry, in Oxfordshire in 1676. Sir Thomas Pennyson gave the fragment to Professor Robert Plot, Professor of Chemistry at Oxford University and first curator of the Ashmolean Museum, who published a description and illustration in his "Natural History of Oxfordshire" in 1676.


      He named it "Scrotum Humanum" as he apparently compared its appearance to a pair of "human testicles".


      So there you are, the first ever discovered dinosaur species was named after the male anatomy.


      What is it with naming animals after sexual organs? We have the Booby, Pussy, Cock, Ass and for fucks sake who decided to name a species of bird Tit!?

      North Korea's diplomatic mission to the UN has 1,300 unpaid NYC parking tickets, going back to the 1990s, owing more than $156,000.


      Multiple countries actually owe fines to the US, for instance Russia reportedly owes over $104,000, Iran has run up $185,000 in fees and Syria has nearly $363,000 in unpaid tickets.


      Including North Korea that's almost $1 million in unpaid fines.


      Even Kim Jong-Un isn't immune to the terrors of traffic wardens.
