Honeycomb
A honeycomb is a mass of Triangular prismatic honeycomb#Hexagonal prismatic honeycomb, hexagonal prismatic cells built from beeswax by honey bees in their beehive, nests to contain their brood (eggs, larvae, and pupae) and stores of honey and pollen. beekeeping, Beekeepers may remove the entire honeycomb to harvest honey. Honey bees consume about of honey to secrete of wax, and so beekeepers may return the wax to the hive after harvesting the honey to improve honey outputs. The structure of the comb may be left basically intact when honey is extracted from it by uncapping and spinning in a centrifugal honey extractor.

Beehive
A beehive is an enclosed structure which houses honey bees, subgenus '' Apis.'' Honey bees live in the beehive, raising their young and producing honey as part of their seasonal cycle. Though the word ''beehive'' is used to describe the nest of any bee colony, scientific and professional literature distinguishes ''nest'' from ''hive''. ''Nest'' is used to discuss colonies that house themselves in natural or artificial cavities or are hanging and exposed. The term ''hive'' is used to describe a manmade structure to house a honey bee nest. Several species of ''Apis'' live in colonies. But for honey production, the western honey bee (''Apis mellifera'') and the eastern honey bee (''Apis cerana'') are the main species kept in hives. The nest's internal structure is a densely packed group of hexagonal prismatic cells made of beeswax, called a honeycomb. The bees use the cells to store food (honey and pollen) and to house the brood (eggs, larvae, and pupae). Beehives serve several ...

Beekeeping
Beekeeping (or apiculture, from ) is the maintenance of bee colonies, commonly in artificial beehives. Honey bees in the genus '' Apis'' are the most commonly kept species but other honey producing bees such as '' Melipona'' stingless bees are also kept. Beekeepers (or apiarists) keep bees to collect honey and other products of the hive: beeswax, propolis, bee pollen, and royal jelly. Other sources of beekeeping income include pollination of crops, raising queens, and production of package bees for sale. Bee hives are kept in an apiary or "bee yard". The earliest evidence of humans collecting honey are from Spanish caves paintings dated 6,000 BCE, however it is not until 3,100 BCE that there is evidence from Egypt of beekeeping being practiced. In the modern era, beekeeping is often used for crop pollination and the collection of its by products, such as wax and propolis. The largest beekeeping operations are agricultural businesses but many small beekeeping operations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honey
Honey is a sweet and viscous substance made by several species of bees, the best-known of which are honey bees. Honey is made and stored to nourish bee colonies. Bees produce honey by gathering and then refining the sugary secretions of plants (primarily floral nectar) or the secretions of other insects, like the honeydew of aphids. This refinement takes place both within individual bees, through regurgitation and enzymatic activity, and during storage in the hive, through water evaporation that concentrates the honey's sugars until it is thick and viscous. Honey bees stockpile honey in the hive. Within the hive is a structure made from wax called honeycomb. The honeycomb is made up of hundreds or thousands of hexagonal cells, into which the bees regurgitate honey for storage. Other honey-producing species of bee store the substance in different structures, such as the pots made of wax and resin used by the stingless bee. Honey for human consumption is collected ...

Honey Bee
A honey bee (also spelled honeybee) is a eusocial flying insect within the genus ''Apis'' of the bee clade, all native to mainland Afro-Eurasia. After bees spread naturally throughout Africa and Eurasia, humans became responsible for the current cosmopolitan distribution of honey bees, introducing multiple subspecies into South America (early 16th century), North America (early 17th century), and Australia (early 19th century). Honey bees are known for their construction of perennial colonial nests from wax, the large size of their colonies, and surplus production and storage of honey, distinguishing their hives as a prized foraging target of many animals, including honey badgers, bears and human hunter-gatherers. Only 8 surviving species of honey bees are recognized, with a total of 43 subspecies, though historically 7 to 11 species are recognized. Honey bees represent only a small fraction of the roughly 20,000 known species of bees. The best-known honey bee is t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beeswax
Bee hive wax complex Beeswax (also known as cera alba) is a natural wax produced by honey bees of the genus ''Apis''. The wax is formed into scales by eight wax-producing glands in the abdominal segments of worker bees, which discard it in or at the hive. The hive workers collect and use it to form cells for honey storage and larval and pupal protection within the beehive. Chemically, beeswax consists mainly of esters of fatty acids and various long-chain alcohols. Beeswax has been used since prehistory as the first plastic, as a lubricant and waterproofing agent, in lost wax casting of metals and glass, as a polish for wood and leather, for making candles, as an ingredient in cosmetics and as an artistic medium in encaustic painting. Beeswax is edible, having similarly negligible toxicity to plant waxes, and is approved for food use in most countries and in the European Union under the E number E901. However, due to its inability to be broken down by the human digestiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hexagonal Tiling
In geometry, the hexagonal tiling or hexagonal tessellation is a regular tiling of the Euclidean plane, in which exactly three hexagons meet at each vertex. It has Schläfli symbol of or (as a Truncation (geometry), truncated triangular tiling). English mathematician John Horton Conway, John Conway called it a hextille. The internal angle of the hexagon is 120 degrees, so three hexagons at a point make a full 360 degrees. It is one of List of regular polytopes#Euclidean tilings, three regular tilings of the plane. The other two are the triangular tiling and the square tiling. Structure and properties The hexagonal tiling has a structure consisting of a regular hexagon only as its prototile, sharing two vertices with other identical ones, an example of monohedral tiling. Each vertex at the tiling is surrounded by three regular hexagons, denoted as 6.6.6 by vertex configuration. The dual of a hexagonal tiling is triangular tiling, because the center of each hexagonal tiling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wax Foundation
Wax foundation or honeycomb base is a plate made of wax forming the base of one honeycomb. It is used in beekeeping to give the bees a foundation on which they can build the honeycomb. Wax foundation is considered one of the most important inventions in modern beekeeping. History Wax foundation was invented by German Johannes Mehring in 1857, a few years after Lorenzo Langstroth, Langstroth designed and patented the Langstroth hive on October 5, 1852. Mehring's wax foundation had only the bottom of the cells, and today's base with the foundation of the cells was invented by US beekeeper Samuel Wagner. The Langstroth patent did not call for foundation and let the bees build their own comb. At first, wax foundations were made in the wax foundation press. The first presses were made of wood, while later presses could be made of plaster, cement, and finally metal, which are the ones used today. Wagner also invented the wax foundation rollers, but never perfected them; the first usab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honeycomb Theorem
The honeycomb theorem, formerly the honeycomb conjecture, states that a regular hexagonal grid or honeycomb has the least total perimeter of any subdivision of the plane into regions of equal area. The conjecture was proven in 1999 by mathematician Thomas C. Hales. Theorem Let \Gamma be any system of smooth curves in \mathbb^2, subdividing the plane into regions (connected components of the complement of \Gamma) all of which are bounded and have unit area. Then, averaged over large disks in the plane, the average length of \Gamma per unit area is at least as large as for the hexagon tiling. The theorem applies even if the complement of \Gamma has additional components that are unbounded or whose area is not one; allowing these additional components cannot shorten \Gamma. Formally, let B(0,r) denote the disk of radius r centered at the origin, let L_r denote the total length of \Gamma\cap B(0,r), and let A_r denote the total area of B(0,r) covered by bounded unit-area components ...

Worker Bee
A worker bee is any female bee that lacks the reproductive capacity of the colony's queen bee and carries out the majority of tasks needed for the functioning of the hive. While worker bees are present in all eusocial bee species, the term is rarely used (outside of scientific literature) for bees other than honey bees, particularly the European honey bee (''Apis mellifera''). Worker bees of this variety are responsible for approximately 80% of the world's crop pollination services. Worker bees are the caste of bee that perform most of the fundamental tasks of the hive, and they are by far the most numerous type of bee. They are much smaller than drones or queen bees, with bodies specialized for nectar and pollen collection. They perform different tasks around the hive progressively over their lifespans in a predictable order based on their age. Worker bees gather pollen in the pollen baskets on their back legs and carry it back to the hive where it is used as food for the devel ...

Thomas Callister Hales
Thomas Callister Hales (born June 4, 1958) is an American mathematician working in the areas of representation theory, discrete geometry, and formal verification. In representation theory he is known for his work on the Langlands program and the proof of the fundamental lemma over the group Sp(4) (many of his ideas were incorporated into the final proof of the fundamental lemma, due to Ngô Bảo Châu). In discrete geometry, he settled the Kepler conjecture on the density of sphere packings, the honeycomb conjecture, and the dodecahedral conjecture. In 2014, he announced the completion of the Flyspeck Project, which formally verified the correctness of his proof of the Kepler conjecture. Biography He received his Ph.D. from Princeton University in 1986 with a dissertation titled ''The Subregular Germ of Orbital Integrals''. Hales taught at Harvard University and the University of Chicago, and from 1993 and 2002 he worked at the University of Michigan. In 1998, Hales submitted ...
