Bic Cristal
The BIC Cristal (stylised as BiC Cristal and also known as the Bic Biro) is an inexpensive, disposable ballpoint pen mass-produced and sold by of , France. It was introduced in 1950 and is the best-selling pen in the world, with the 100 billionth sold in September 2006. It has become the archetypal ballpoint pen and is considered ubiquitous, to the extent that the Museum of Modern Art has made it a permanent part of its collection. Its hexagonal form and design mimics a standard pencil and it is sold in six types of point and 18 colors around the world. History In 1930, László Bíró, a Hungarian-Argentine inventor observed children playing with marbles in a puddle, noticing that the marbles left a trail of water in their wake. Inspired by this observation, he conceived of a mechanism for a pen that used a ball-shaped metal nib to place ink onto a page. He shared his idea with his brother György, a chemist, and together they began researching and experimenting to create suc ...

Ballpoint Pen
A ballpoint pen, also known as a biro (British English), ball pen (Hong Kong, Indian, Indonesian, Pakistani, and Philippine English), or dot pen ( Nepali English and South Asian English), is a pen that dispenses ink (usually in paste form) over a metal ball at its point, i.e., over a "ball point". The metals commonly used are steel, brass, or tungsten carbide. The design was conceived and developed as a cleaner and more reliable alternative to dip pens and fountain pens, and it is now the world's most-used writing instrument; millions are manufactured and sold daily. It has influenced art and graphic design and spawned an artwork genre. History Origins The concept of using a "ball point" within a writing instrument to apply ink to paper has existed since the late 19th century. In these inventions, the ink was placed in a thin tube whose end was blocked by a tiny ball, held so that it could not slip into the tube or fall out of the pen. The first patent for a ballpoi ...

4 Bic Cristal Pens And Caps
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is a square number, the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. Evolution of the Hindu-Arabic digit Brahmic numerals represented 1, 2, and 3 with as many lines. 4 was simplified by joining its four lines into a cross that looks like the modern plus sign. The Shunga would add a horizontal line on top of the digit, and the Kshatrapa and Pallava evolved the digit to a point where the speed of writing was a secondary concern. The Arabs' 4 still had the early concept of the cross, but for the sake of efficiency, was made in one stroke by connecting the "western" end to the "northern" end; the "eastern" end was finished off with a curve. The Europeans dropped the finishing curve and gradually made the digit less cursive, ending up with a digit very close to the original Brahmin cross. While the shape of the character for ...

Museum Of Failure
The Museum of Failure is a museum that features a collection of failed products and services. The touring exhibition provides visitors with a learning experience about the critical role of failure in innovation. According to its founder, Samuel West, the goal of the museum is to help people recognize the "need to accept failure if we want progress", and to encourage companies to learn more from their failures without resorting to "cliches". History West's 2016 visit to the Museum of Broken Relationships in Zagreb inspired the concept of the museum. Museum founder and curator Samuel West reportedly registered a domain name for the museum and later realized he had misspelled the word museum. The Swedish Innovation Authority (Vinnova) partially funded the museum. The exhibition opened on 7 June 2017 in Helsingborg, Sweden. The exhibit reopened at Dunkers Kulturhus on 2 June 2018, before closing in January 2019. A temporary exhibit opened in Los Angeles in December 2017. The Los A ...

Edinburgh Festival
__NOTOC__ This is a list of Arts festival, arts and cultural festivals regularly taking place in Edinburgh, Scotland. The city has become known for its festivals since the establishment in 1947 of the Edinburgh International Festival and the Edinburgh Festival Fringe which runs alongside it. The latter is the largest event of its kind in the world. The term ''Edinburgh Festival'' is commonly used, but there is no single festival; the various festivals are put on by separate, unrelated organisations. However they are widely regarded as part of the same event, particularly the various festivals that take place simultaneously in August each year. The term ''Edinburgh Festival'' is often used to refer more specifically to the Fringe, being the largest of the festivals; or sometimes to the International Festival, being the original "official" arts festival. Within the industry, people refer to all the festivals collectively as the ''Edinburgh Festivals'' (plural). The festivals ...

Kenyan Shilling
The shilling (; abbreviation: KSh; ISO 4217, ISO code: KES) is the currency of Kenya. It is divided into 100 cents. The Central Bank of Kenya Act cap 491, mandated the printing and minting of the Kenyan shilling currency. Notation Prices in the Kenyan shilling are written in the form of , where x is the amount in shillings, while y is the amount in cents. An equals sign or hyphen represents zero amount. For example, 50 cents is written as "" and 100 shillings as "" or "100/". Sometimes the abbreviation ''KSh'' is prefixed for distinction. If the amount is written using words as well as numerals, only the prefix is used (e.g. KSh 10 million). This pattern was modelled on Pound sterling, sterling's Pound sterling#Pre-decimal, pre-decimal notation, in which amounts were written in some combination of pounds (£), shillings (s), and pence (d, for denarius). In that notation, amounts under a pound were notated only in shillings and pence. History The Kenyan shilling r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Polystyrene
Polystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to air and water vapor and has a relatively low melting point. Polystyrene is one of the most widely used plastics, with the scale of its production being several million tonnes per year. Polystyrene is naturally transparent to visible light, but can be colored with colorants. Uses include protective packaging (such as packing peanuts and optical disc jewel cases), containers, lids, bottles, trays, tumblers, disposable cutlery, in the making of models, and as an alternative material for phonograph records. As a thermoplastic polymer, polystyrene is in a solid (glassy) state at room temperature but flows if heated above about 100 °C, its glass transition temperature. It becomes rigid again when cooled.

Polypropylene
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer Propene, propylene. Polypropylene belongs to the group of polyolefins and is Crystallization of polymers#Degree of crystallinity, partially crystalline and Chemical polarity#Nonpolar molecules, non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant. It is a white, mechanically rugged material and has a high chemical resistance. Polypropylene is the second-most widely produced Commodity plastics, commodity plastic (after polyethylene). History Phillips Petroleum chemists J. Paul Hogan and Robert Banks (chemist), Robert Banks first demonstrated the polymerization of propylene in 1951. The stereoselective polymerization to the isotactic was discovered by Giulio Natta and Karl Rehn in March 1954. This pioneering discovery led to large-scale commercial producti ...

Vitrification
Vitrification (, via French ') is the full or partial transformation of a substance into a glass, that is to say, a non- crystalline or amorphous solid. Glasses differ from liquids structurally and glasses possess a higher degree of connectivity with the same Hausdorff dimensionality of bonds as crystals: dimH = 3. In the production of ceramics, vitrification is responsible for their impermeability to water. Vitrification is usually achieved by heating materials until they liquify, then cooling the liquid, often rapidly, so that it passes through the glass transition to form a glassy solid. Certain chemical reactions also result in glasses. In terms of chemistry, vitrification is characteristic for amorphous materials or disordered systems and occurs when bonding between elementary particles (atoms, molecules, forming blocks) becomes higher than a certain threshold value. Thermal fluctuations break the bonds; therefore, the lower the temperature, the higher the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Tungsten Carbide
Tungsten carbide (chemical formula: ) is a carbide containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through sintering for use in industrial machinery, engineering facilities, molding blocks, cutting tools, chisels, abrasives, armor-piercing bullets and jewelry. Tungsten carbide is approximately three times as stiff as steel, with a Young's modulus of approximately 530–700 GPa, and is twice as dense as steel. It is comparable with corundum (α- ) in hardness, approaching that of a diamond, and can be polished and finished only with abrasives of superior hardness such as cubic boron nitride and diamond. Tungsten carbide tools can be operated at cutting speeds much higher than high-speed steel (a special steel blend for cutting tools). Tungsten carbide powder was first synthesized by H. Moissan in 1893, and the industrial production of the cemented form starte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
