Josef Průša
Josef Průša (born 23 February 1990) is a Czech businessman and 3D printer developer. He is the owner of Prusa Research. Biography Josef Průša was born on 23 February 1990 in Havlíčkův Brod, Czechoslovakia. He studied applied computer science at the University of Economics in Prague, but did not complete it. At the age of 19 he began designing 3D printers, and in 2012 he founded Prusa Research. The foundation for his business was his collaboration with the RepRap project, a 3D printer project that can partially replicate itself and is available as open-source hardware. He has lectured on 3D printing and open-source hardware. He also has taught Arduino at the Faculty of Arts, Charles University, and taught at the Academy of Arts, Architecture and Design in Prague. In 2021, Forbes ranked him as the 75th richest Czech with assets of 4.3 billion Czech koruna.

Czech Koruna
The koruna, or crown (sign: Kč; code: CZK, ), has been the currency of the Czech Republic since 1993. The koruna is one of the European Union's eight currencies, and the Czech Republic is legally bound to adopt the euro in the future. The official name in Czech is (plural , though the zero-suffixed genitive plural form is used on banknotes and coins of value 5 Kč or higher). The ISO 4217 code is CZK and the local acronym is Kč, which is placed after the numeric value (e.g., "50 Kč") or sometimes before it (as is seen on the 10-koruna coin). One crown is made up of 100 '' hellers'' (abbreviated as "h", official name in Czech: singular: , nominative plural: , genitive plural: – used with numbers higher or equal to 5 – e.g. ), but hellers have now been withdrawn from circulation, and the smallest unit of physical currency is 1 Kč. History In 1892, the Austro-Hungarian krone replaced the gulden at the rate of two kronen to one gulden (which is also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From Havlíčkův Brod
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Living People
Purpose: Because living persons may suffer personal harm from inappropriate information, we should watch their articles carefully. By adding an article to this category, it marks them with a notice about sources whenever someone tries to edit them, to remind them of WP:BLP (biographies of living persons) policy that these articles must maintain a neutral point of view, maintain factual accuracy, and be properly sourced. Recent changes to these articles are listed on Special:RecentChangesLinked/Living people. Organization: This category should not be sub-categorized. Entries are generally sorted by family name In many societies, a surname, family name, or last name is the mostly hereditary portion of one's personal name that indicates one's family.

1990 Births
Year 199 ( CXCIX) was a common year starting on Monday of the Julian calendar. At the time, it was sometimes known as year 952 ''Ab urbe condita''. The denomination 199 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

RepRap
RepRap (a contraction of ''replicating rapid prototyper'') is a project to develop low-cost 3D printers that can print most of their own components. As open designs, all of the designs produced by the project are released under a free software license, the GNU General Public License. Due to the ability of these machines to make some of their own parts, authors envisioned the possibility of cheap RepRap units, enabling the manufacture of complex products without the need for extensive industrial infrastructure. They intended for the RepRap to demonstrate evolution in this process as well as for it to increase in number exponentially. A preliminary study claimed that using RepRaps to print common products results in economic savings. The RepRap project started in England in 2005 as a University of Bath initiative, but it is now made up of hundreds of collaborators worldwide.

Prusa I3
The Prusa i3 is a family of fused filament fabrication 3D printers, manufactured by Czech company Prusa Research under the trademarked name Original Prusa i3. Part of the RepRap project, Prusa i3 printers were called the most used 3D printer in the world in 2016. The first Prusa i3 was designed by Josef Průša in 2012, and was released as a commercial kit product in 2015. The latest model (Prusa MK4S on sale as of August 2024) is available in both kit and factory assembled versions. The Prusa i3's comparable low cost and ease of construction and modification made it popular in education and with hobbyists and professionals, with the Prusa i3 model MK2 printer receiving Prusa i3#Recognition, several awards in 2016. The i3 series is released under an Open-source hardware, open source license, which has led to many other companies and individuals producing Prusa i3#Variants, variants and clones of the design. The i3 moniker refers to the printer being the third iteration of the des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jiří Březina
In fluid dynamics, the Reynolds number () is a dimensionless quantity that helps predict fluid flow patterns in different situations by measuring the ratio between inertial and viscous forces. At low Reynolds numbers, flows tend to be dominated by laminar (sheet-like) flow, while at high Reynolds numbers, flows tend to be turbulent. The turbulence results from differences in the fluid's speed and direction, which may sometimes intersect or even move counter to the overall direction of the flow ( eddy currents). These eddy currents begin to churn the flow, using up energy in the process, which for liquids increases the chances of cavitation. The Reynolds number has wide applications, ranging from liquid flow in a pipe to the passage of air over an aircraft wing. It is used to predict the transition from laminar to turbulent flow and is used in the scaling of similar but different-sized flow situations, such as between an aircraft model in a wind tunnel and the full-size ver ...

Mensa International
Mensa International is the largest and oldest high-IQ society in the world. It is a non-profit organization open to people who score at the 98th percentile or higher on a standardised, supervised IQ or other approved intelligence test. Mensa formally comprises national groups and the umbrella organisation Mensa International, with a registered office in Caythorpe, Lincolnshire, England, which is separate from the British Mensa office in Wolverhampton. Etymology The word ''mensa'' (, ) is Latin for ' table', as is symbolised in the organisation's logo, and was chosen to demonstrate the round-table nature of the organisation: the coming together of equals. History Australian Roland Berrill and Lancelot Ware, a British scientist and lawyer, founded Mensa at Lincoln College, in Oxford, England in 1946, with the intention of forming a society for the most intelligent, with the only qualification being a high IQ. The society was ostensibly to be non-political in its aims and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
