The People's Republic of China has administrative control over twenty-two provinces; the government of the PRC considers Taiwan to be its twenty-third region. Apart from provinces, there are five independent regions, each with a designated minority group; four municipalities; and two Special Administrative Regions that enjoy considerable autonomy.

The twenty-two provinces, five autonomous regions and four municipalities can be jointly referred to as "mainland China", a term which usually excludes Hong Kong and Macau.

Veterinary medicine is the application of medical, diagnostic, and therapeutic principles to companion, domestic, exotic, wildlife, and production animals. Veterinary Science is concerned with the scientific basis of animal production, health and disease. It requires the acquisition and application of scientific knowledge in several disciplines and uses technical skills towards the solution of animal production, health, management and welfare troubles.

Veterinary medicine is informally as old as the human/animal bond but in recent years has extended exponentially because of the availability of advanced diagnostic and therapeutic techniques for most species. Animals nowadays often receive advanced medical, dental, and surgical care including insulin injections, root canals, hip replacements, cataract extractions, and pacemakers.

Veterinarians assist in ensuring the quality, quantity, and security of food supply by working to maintain the health of livestock and inspecting the meat itself. Veterinary scientists are very important in chemical, biological, and pharmacological research.

Aerospace engineering is the branch of engineering concerning aircraft, spacecraft and related topics. It is often called aeronautical engineering, particularly when referring solely to aircraft, and astronautical engineering, when referring to spacecraft. Some of the elements of aerospace engineering are:

• Aerodynamics - the study of fluid flow around objects such as wings or through objects such as wind tunnels (see also lift and aeronautics)
  
• Propulsion - the energy to move a vehicle through the air (or in outer space) is provided by internal combustion engines, jet engines, or rockets (see also propeller and Spacecraft Propulsion)
  
• Control or flight dynamics - the study of maneuvering vehicles to achieve the desired position and attitude (that is, which way the vehicle is pointing) (see also Astrodynamics)
  
• Structures - design of the physical configuration of the craft to withstand the forces encountered during flight. Aerospace engineering aims very much at keeping structures lightweight.
  
• Materials - related to structures, aerospace engineering also studies the materials of which the aerospace structures are to be built. New materials with very specific properties are invented, or existing ones are modified to improve their performance.
  
• Aeroelasticity - the interaction of aerodynamic forces and structural flexibility, potentially causing flutter, divergence, etc

The basis of most of these elements lies in theoretical mathematics, such as fluid dynamics for aerodynamics or the equations of motion for flight dynamics. However, there is also a large empirical component. Historically, this empirical component was derived from testing of scale models and prototypes, either in wind tunnels or in the free atmosphere. More recently, advances in computing have enabled the use of computational fluid dynamics to simulate the behavior of fluid, reducing time and expense spent on wind-tunnel testing.

Additionally, aerospace engineering addresses the integration of all components that constitute an aerospace vehicle (subsystems including power, communications, thermal control, life support, etc.) and its life cycle (design, temperature, pressure, radiation, velocity, life time...), leading to extraordinary challenges and solutions specific to the domain of aerospace systems engineering.

The Titanic was a White Star Line ocean liner built at the Harland and Wolff shipyard in Belfast, Ireland, and was designed to compete with rival company Cunard Line's Lusitania and Mauretania. Titanic, along with its Olympic class sisters, Olympic and the soon to be built Britannic (originally named Gigantic ^[3]), were intended to be the largest, most luxurious ships ever to operate. Titanic was designed by Harland and Wolff chairman Lord Pirrie, head of Harland and Wolff's design department Thomas Andrews and general manager Alexander Carlisle, with the plans regularly sent to White Star Line's managing director J. Bruce Ismay for suggestions and approval. Construction of the RMS Titanic, funded by the American J.P. Morgan and his International Mercantile Marine Co., began on March 31, 1909. Titanic's hull, No. 401, was launched two years and two months later on May 31, 1911, the same day that the Olympic (hull No. 400) would begin its maiden voyage. Titanic's outfitting was completed March 31 the following year. Titanic was 882 ft 9 in (269 m) long and 92 ft 6 in (28 m) at its beam, it had a gross tonnage of 46,328 tons, and a height from the water line to the boat deck of 60 ft (18 m). Although it enclosed more space and therefore had a larger gross tonnage, the hull was exactly the same length as Titanic's sister ship Olympic. Titanic contained two reciprocating four-cylinder, triple expansion, inverted steam engines and one low pressure Parsons turbine which powered three propellers. There were 29 boilers fired by 159 coal burning furnaces that made possible a top speed of 23 knots (43 km/h). Only three of the four 63 feet (19 m) tall funnels were functional; the fourth funnel, which only served as a vent, was added to make the ship look more impressive. The ship could hold a total of 3,547 passengers and crew and, because it carried mail, its name was given the prefix RMS (Royal Mail Steamer) as well as SS (Steam Ship).

The Model T (colloquially known as the Tin Lizzie and the Flivver) was an automobile produced by Henry Ford's Ford Motor Company from 1908 through 1928. The first production Model T was built on September 27, 1908 at the Piquette Plant in Detroit, Michigan. Cars built before 1919 are classed as veteran cars and later models vintage cars.

There were several cars produced or prototyped by Henry Ford from the founding of the company in 1903 until the Model T came along. Although he started at the Model A, there were not 19 production models; some were only prototypes. The production model immediately before the Model T was the Ford Model S [1], an upgraded version of the company's largest success to that point, the Model N. For some reason, the follow-on was the Model A and not the Model U.

Ford's Piquette plant could not keep up with demand for the Model T and only 11 cars were built there during the first full month of production. In 1910, after assembling nearly 12,000 Model T's, Henry Ford moved the company to the new Highland Park complex. The Model T was the first automobile mass produced on assembly lines with completely interchangeable parts, marketed to the middle class. To speed assembly, between 1915 and 1925 it was only available in one color, black. Black paint was also cheaper and more durable. Henry Ford is reputed to have made the statement "Any customer can have a car painted any color that he wants so long as it is black." Model Ts in different colors were produced from 1908 to 1914, and then again from 1926 to 1927.
