Diversity[1]
113 families, c. 46,000 species

Spiders (order Araneae) are air-breathing arthropods that have eight legs and chelicerae with fangs able to inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other orders of organisms.[2] Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every habitat with the exceptions of air and sea colonization. As of November 2015, at least 45,700 spider species, and 113 families have been recorded by taxonomists.[1] However, there has been dissension within the scientific community as to how all these families should be classified, as evidenced by the over 20 different classifications that have been proposed since 1900.[3]

Anatomically, spiders differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax and abdomen, and joined by a small, cylindrical pedicel. Unlike insects, spiders do not have antennae. In all except the most primitive group, the Mesothelae, spiders have the most centralized nervous systems of all arthropods, as all their ganglia are fused into one mass in the cephalothorax. Unlike most arthropods, spiders have no extensor muscles in their limbs and instead extend them by hydraulic pressure.

 

 

McLAREN P1

The McLaren P1 is a British limited-production plug-in hybrid sports carproduced by McLaren Automotive. Debuted at the 2012 Paris Motor Show,retail began in the UK in October 2013 and all 375 units were sold out by November. Production ended in early December 2015.[8] The United States accounted for 34% of the units and Europe for 26%.[8]

It is considered to be the successor to the F1, utilising hybrid power and Formula 1 technology, but does not have the same three-seat layout. It was later confirmed that the Speedtail served as the actual successor to the F1. Like the F1, the P1 has a mid-enginerear wheel drive design that used a carbon fibre monocoque and roof structure safety cage concept called MonoCage, which is a development of the MonoCell first used in the MP4-12C and then in subsequent models. Its main competitors were the LaFerrariand the Porsche 918. They are all similar in specifications and performance, and in a race around Silverstone circuit they were all within half a second of each other, the P1 finishing first at 58.24 seconds and the LaFerrari finishing last at 58.58 seconds; the 918 was in-between with 58.46 seconds.

P1 GTR (58 units) and P1 LM (5 units) variants were produced after the initial run of 375 cars.

13 eXperimental Prototype ‘XP’, 5 Validation Prototype ‘VP’ and 3 Pre-Production ‘PP’ P1s were produced by McLaren before the production started out,a number of which have been refurbished, modified and sold to customers.

FERRARI LA FERRARI

The LaFerrari, project name F150 (also unofficially referred to as the Ferrari LaFerrari or Ferrari F70)is a limited production hybrid sports car built by Italian automotive manufactuter Ferrari. LaFerrari literally means “The Ferrari” in Italian and in some other Romance languages, in this context in the sense that it is the “definitive” Ferrari.

Christmas is an annual festival commemorating the birth of Jesus Christ,[8][9] observed primarily on December 25[4][10][11]as a religious and cultural celebration among billions of people around the world.[2][12][13] A feast central to the Christianliturgical year, it is preceded by the season of Advent or the Nativity Fast and initiates the season of Christmastide, which historically in the West lasts twelve days and culminates on Twelfth Night;[14] in some traditions, Christmastide includes an octave.[15] Christmas Day is a public holiday in many of the world’s nations,[16][17][18] is celebrated religiously by a majority of Christians,[19] as well as culturally by many non-Christians,[1][20] and forms an integral part of the holiday seasoncentered around it.

The traditional Christmas narrative, the Nativity of Jesus, delineated in the New Testament says that Jesus was born in Bethlehem, in accordance with messianic prophecies.[21] When Joseph and Mary arrived in the city, the inn had no room and so they were offered a stable where the Christ Child was soon born, with angels proclaiming this news to shepherds

MUSTANG

 

The Ford Mustang is an American car manufactured by Ford. It was originally based on the platform of the second generation North American Ford Falcon, a compact car.The original 1962 Ford Mustang I two-seater concept car had evolved into the 1963 Mustang II four-seater concept car which Ford used to pretest how the public would take interest in the first production Mustang. The 1963 Mustang II concept car was designed with a variation of the production model’s front and rear ends with a roof that was 2.7 inches shorter. Introduced early on April 17, 1964 (16 days after the Plymouth Barracuda), and thus dubbed as a “1964½” by Mustang fans, the 1965 Mustang was the automaker’s most successful launch since the Model A.The Mustang has undergone several transformations to its current sixth generation.

The Mustang created the “pony car” class of American muscle cars, affordable sporty coupes with long hoods and short rear decks, and gave rise to competitors such as the Chevrolet Camaro, Pontiac FirebirdAMC Javelin,Chrysler‘s revamped Plymouth Barracuda, and the second generation Dodge Challenger.The Mustang is also credited for inspiring the designs of coupés such as the Toyota Celica and Ford Capri, which were imported to the United States.

As of August 2018, over 10 million Mustangs have been produced in the U.S.

Mathematics includes the study of such topics as quantity, structure, space, and change. Mathematicians seek and use patterns to formulate new conjectures; they resolve the truth or falsity of conjectures by mathematical proof.

Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3500 to 3000 BCE.
