What kind of a reply is this, lol? The kind a person with no arguments gives, when you don't have anything to say you resolve to insults, hahaha.
Yes, ofcourse the cyrillic alphabet was invented in the First Bulgarian Empire in the 890s at the Preslav Literary School and later at the Ohrid Literary School under Boris I of Bulgaria, and was created by Cyril's students who were banished from Great Moravia and were given refuge in Bulgaria.
Oh, you didn't know that Cyril and Methodius created the glagolitic alphabet, which is very different than the cyrillic alphabet (named in their honour by their disciples, whose names I'm sure you don't know, hah).
But unlike you, I'm not kidding myself, the cyrillic alphabet is essentially just like the greek alphabet and the majority of uncial Cyrillic letters were identical to their Greek uncial counterparts. In fact most of the macedonian (and thus the bulgarian names, since our nations share the same slavic DNA, language, culture, traditions, etc., but you like to deny that fact and hate on us the way the poor and deluded north-koreans hate on South Korea, hah) are essentially derived from greek names. Btw I wonder why Alexander The Great spoke greek, and the modern macedonians speak another slavic language...
As far as Cyril and Methodius are concerned nobody knows for sure what was their ethnicity, I bet not even they knew their own origins. And the biggest cities of Byzantium at the time were prolly something like the modern-day New York, a so called melting pot.

You should be ashamed of yourself for attacking and insulting a whole country in such a low way, that was totally uncalled for and not connected to the imdb topic. I bet Cyril and Methodius are not happy with your blabber (if they're watching from the skies somehow), even more so when our nations are so historically close like brothers and considering that Bulgaria has always supported FYROMacedonia.

But to answer your insults (not with insults; I can too try to insinuate some inflated stereotyped BullSht without any factual proof about your insignificant nation, but I'm not gonna do it), here's what I found after a quick research:

- First electronic digital computer was prototyped in 1939 by John Atanasoff
- Stamen Grigorov - discovered the true cause for the existence of natural yogurt - Lactobacillus bulgaricus; He also made a major contribution to the creation of an anti-tuberculosis vaccine
- Carl Djerassi created the birth-control/oral contraceptive pill
- Dimitar Paskov - created the medicine Nivalin/Galantamine
- Georgi Nadjakov - discovered the photoelectret state essential to modern photocopying
- Roumen Antonov - inventor of the automatic transmission bearing his name for Toyota Prius
- Peter Petroff - devised the Digital Electronic Watch; invented world's first wireless heart monitor; developed the world's first computerized pollution monitoring system, telemetry devices for the world's first weather and communications satellites; he was instrumental in the evolution of the NASA space program & recruited by Wernher von Braun
- Ivan Mitev - discovered the sixth tone in the heart
- Professor Yul Brown (Ilia Georgiev Valkov (Vulkov) - born in Varna on April 22, 1922) finds the Brown's gas and create Brown's generator. The story begins in 1971.
- Assen Jordanoff - inventor, engineer, and aviator; his contribution was essential to the advancement of US aviation, thanks to his instructional/analytical books in the field of aeronautics and its processes, as well as thanks to the direct application of his engineering and practical skills in the building of aircraft
- Stefka Kostadinova - World Record holder and 2 World Titles High Jump (1987, 1995)
- Yordanka Donkova - World Record holder and 1 World Title Hurdling (1988)
- Hristo Stoichkov won The Ballon d'Or (Golden Ball) in 1994 for being the best football player in the world after finishing 4th in the World Cup with the Bulgarian national team the same year. He's an FC Barcelona legend.
- Ivet Lalova - currently the fastest non-African sprinter woman
- Maria Gigova - 3 Rhythmic Gymnastics World Titles (1969, 1971, 1973), Guinness World Records
- Maria Petrova - 3 Rhythmic Gymnastics World Titles (1993, 1994, 1995), Guinness World Records
- Albena Denkova - World Figure Skating Champion Ice dancing (pairs) (2006, 2007)
- Valentin Yordanov - 2 Olympic, 7 World and 7 European Titles in Wrestling
+ many more renowned sportists
- in 2012 both the male and female winners of the World Beatbox Championship were from Bulgaria - Skiller and Pe4enkata respectively.
- International MENSA IQ testing completed in 2004 identified as the world's smartest woman (and one of the smartest people in the world) Daniela Simidchieva of Bulgaria, who has an IQ of 200.
- Bulgaria's advanced education is right up with the top countries in the world, ranking fifth amongst all countries in sciences and eleventh in mathematics, according to The World Bank and The Economist. Ranking second in the world in IQ tests (MENSA International), Bulgaria also ranks second in the world in SAT scores.
Lastly, Bulgaria ranked 8th globally in certified IT professionals, according to the Brainbench Global IT IQ Report.
- At the Tokyo International Mathematics Olympiad in 2003 Bulgaria finished in first place from a total of 82 participating countries. Bulgaria also became one of only four countries in the history of the International Mathematics Olympiad to win that competition by having all six of its team members finish with gold medals.
- In 1912, during the First Balkan War, Bulgarian Air Force pilot Christo Toprakchiev suggested the use of aircraft to drop "bombs" (called grenades in the Bulgarian army at this time) on Turkish positions. Captain Simeon Petrov developed the idea and created several prototypes by adapting different types of grenades and increasing their payload.
On 16 October 1912, observer Prodan Tarakchiev dropped two of those bombs on the Turkish railway station of Karagac (near the besieged Edirne) from an Albatros F.2 aircraft piloted by Radul Milkov, for the first time in this campaign.
After a number of tests, Petrov created the final design, with improved aerodynamics, an X-shaped tail, and an impact detonator. This version was widely used by the Bulgarian Air Force during the siege of Edirne. A copy of the plans was later sold to Germany and the bomb, codenamed "Chataldzha", remained in mass production until the end of World War I.
