A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically

A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster.
A broad range of industrial and consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devices like personal computers and mobile devices like smartphones. Computers power the Internet, which links billions of other computers and users.

Early computers were meant to be used only for calculations. Simple manual instruments like the abacus have aided people in doing calculations since ancient times. Early in the Industrial Revolution, some mechanical devices were built to automate long, tedious tasks, such as guiding patterns for looms. More sophisticated electrical machines did specialized analog calculations in the early 20th century. The first digital electronic calculating machines were developed during World War II. The first semiconductor transistors in the late 1940s were followed by the silicon-based MOSFET (MOS transistor) and monolithic integrated circuit chip technologies in the late 1950s, leading to the microprocessor and the microcomputer revolution in the 1970s. The speed, power and versatility of computers have been increasing dramatically ever since then, with transistor counts increasing at a rapid pace (as predicted by Moore's law), leading to the Digital Revolution during the late 20th to early 21st centuries.

C onventionally, a modern computer consists of at least one processing element, typically a central processing unit (CPU) in the form of a microprocessor, together with some type of computer memory, typically semiconductor memory chips. The processing element carries out arithmetic and logical operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices include input devices (keyboards, mice, joystick, etc.), output devices (monitor screens, printers, etc.), and input/output devices that perform both functions (e.g., the 2000s-era touchscreen). Peripheral devices allow information to be retrieved from an external source and they enable the result of operations to be saved and retrieved.

3D printing or additive manufacturing is a process of making three dimensional objects from a digital file.

The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced cross-section of the object.

There is one exception though, and it’s called volumetric 3D printing. With volumetric printing entire structures can be formed at once without the need for layer-by-layer fabrication. It’s worth noting, however, that as of now, volumetric technology is primarily in the research phase.

3D printing is the opposite of subtractive manufacturing which is cutting out / hollowing out a block of material with for instance a milling machine.

3D printing enables you to produce complex shapes using less material than traditional manufacturing methods.Adoption of 3D printing has reached critical mass as those who have yet to integrate additive manufacturing somewhere in their supply chain are now part of an ever-shrinking minority. Where 3D printing was only suitable for prototyping and one-off manufacturing in the early stages, it is now rapidly transforming into a production technology.

Most of the current demand for 3D printing is industrial in nature. Acumen Research and Consulting forecasts the global 3D printing market to reach $41 billion by 2026.

Cultural life
England’s contribution to both British and world culture is too vast for anything but a cursory survey here. Historically, England was a very homogeneous country and developed coherent traditions, but, especially as the British Empire expanded and the country absorbed peoples from throughout the globe, English culture has been accented with diverse contributions from Afro-Caribbeans, Asians, Muslims, and other immigrant groups. Other parts of the United Kingdom have experienced the same social and cultural diversification, with the result that England is not always distinguishable from Wales and Scotland or even Northern Ireland. The former insularity of English life has been replaced by a cosmopolitan familiarity with all things exotic: fish and chips have given way to Indian, Chinese, and Italian cuisine, guitar-based rock blends with South Asian rap and Afro-Caribbean salsa, and the English language itself abounds in neologisms drawn from nearly every one of the world’s tongues.
Even as England has become ever more diverse culturally, it continues to exert a strong cultural influence on the rest of the world. English music, film, and literature enjoy wide audiences overseas, and the English language has gained ever-increasing currency as the preferred international medium of cultural and economic exchange.
Daily life and social customs
Historically, English daily life and customs were markedly different in urban and rural areas. Indeed, much of English literature and popular culture has explored the tension between town and country and between farm and factory. Today, even though the English are among the world’s most cosmopolitan and well-traveled people, ties to the rural past remain strong. Urbanites, for example, commonly retire to villages and country cottages, and even the smallest urban dwelling is likely to have a garden.
Another divide, though one that is fast disappearing, is the rigid class system that long made it difficult for nonaristocratic individuals to rise to positions of prominence in commerce, government, and education. Significant changes have accompanied the decline of the class system, which also had reinforced distinctions between town and country and between the less affluent north of England and the country’s wealthy south. For example, whereas in decades past English radio was renowned for its “proper” language, the country’s airwaves now carry accents from every corner of the country and its former empire, and the wealthy are likely to enjoy the same elements of popular culture as the less advantaged.Historically, English daily life and customs were markedly different in urban and rural areas.

"Handcraft of the world"

“The points to be born in mind in children’s handicrafts are: (a) that they should not be employed in the making futilities such as pea and stick work, paper mats, and the like; (b) that they should be taught slowly and carefully what they are to do; (c) that slipshod work should not be allowed; (d) and that, therefore, the children’s work should be kept well within their compass.”
-Charlotte Mason, Volume 1
Handicrafts are made to be beautiful and useful. While there is a time and place for glitter and glue, handicrafts allow a child to develop multiple skills that will develop with them into adulthood. Handicrafts build upon one another, provide an outlet to learn new hobbies.
Keeping these principles in mind, we have developed a year-long program for students ages 8 and up. There are 18 crafts that can help connect your child to the material they are learning. Inspired by a love of people all over the world, we have written a background history of the projects to help learn from other cultures. All of these crafts take inspiration from others and have been adapted to a handicraft format with the utmost respect to the culture and people from whom they were inspired.
