The National Academy of Sciences (NAS) is a United States nonprofit, non-governmental organization. NAS is part of the National Academies of Sciences, Engineering, and Medicine, along with the National Academy of Engineering (NAE) and the National Academy of Medicine (NAM).

As a national academy, new members of the organization are elected annually by current members, based on their distinguished and continuing achievements in original research. Election to the National Academy is one of the highest honors in the scientific field. Members of the National Academy of Sciences serve pro bono as "advisers to the nation" on science, engineering, and medicine. The group holds a congressional charter under Title 36 of the United States Code.

Founded in 1863 as a result of an Act of Congress that was approved by Abraham Lincoln, the NAS is charged with "providing independent, objective advice to the nation on matters related to science and technology. … to provide scientific advice to the government 'whenever called upon' by any government department."[2]

The Academy receives no compensation from the government for its services.[3]

The Academy currently has 2,984 members and international members. Existing members elect new members for life. Up to 120 members are elected every year; up to 30 foreign citizens may be elected as international members annually. The election process begins with a formal nomination, followed by a vetting period, and culminates in a final ballot at the Academy's annual meeting in April each year. Members are affiliated with a section -- a specific scientific field -- in one of six so-called "classes": (1) Physical and Mathematical Sciences; (2) Biological Sciences; (3) Engineering and Applied Sciences; (4) Biomedical Sciences; (5) Behavioral and Social Sciences; and (6) Applied Biological, Agricultural, and Environmental Sciences.[6] Since its founding, the Academy has elected 6,457 members. Harvard University is associated with the most members (329), some 5% of the all-time total. The top ten institutions, half of which are Ivy League universities, account for nearly 28% of all members ever elected.[11]

Colonial-style houses are simple rectangular homes that became popular in the 1600s as colonists settled the East Coast. These homes have many variations due to the fact that new communities all over the world built Colonial-style homes to suit their culture.

British Colonial style is the most common and recognizable Colonial home. Its key features include:

• A side-gabled roof
• Two floors
• A centered front door
• Symmetrical windows on either side of the door

The rectangular shape and interest in symmetry are seen in other Colonial house styles, too. Materials and decorative features can vary by region, as some Colonial houses sport brick exteriors and ornate trim, while others showcase shingle siding and simple shutters.

These are also some of the cheapest types of houses to build.

Mediterranean home styles are made of stucco, so they’re most common in warm climate states like Arizona and California. These homes grew in popularity in the 1920s and ‘30s after being featured as homes for the rich and famous on the silver screen.

Mediterranean-style homes include Spanish and Italian architectural elements. These key features make them easy to spot:

• Stucco walls painted white or brown
• Classic red tile roofs
• Arched doorways and windows
• Ornamentation including wrought iron, heavy doors, and decorative tiles

Mediterranean homes still carry the feelings of class and luxury they were built with over 100 years ago, with an added element of history and charm.

Contemporary homes resemble the modern homes of the mid-20th century with a renewed emphasis on sustainability. Current contemporary styles are rooted in minimalism, which you can see in these key features:

• Asymmetrical exterior
• Clean lines
• Open floor plan layout
• Geometry highlighted in its structure
• Sustainable building materials and features

Contemporary homes aim to find beauty in a simple and appealing design with ties to nature and more warmth than modern home styles offer.

Despite the car initially being built in 1885 in Germany, American manufacturers completely dominated the automotive industry of the mid-twentieth century. Applaud be to Henry Ford, who established the first conveyor assembly line for his Model T on December 1, 1913. This creation reduced the production time of one vehicle from 12 hours to an hour and 33 minutes, making it a lot cheaper. Ford’s goal was to make automobiles accessible to everyone, and he achieved it. Nowadays, around 91% of American households own at least one car. 

Suburbanization

Before vehicles became widely available, people who lived in the city worked in the city, while most of those who settled in the country were farmers. Now that it was possible to travel vast distances in a short amount of time, the thought of dwelling away from the bustling downtown while still being able to work there looked tempting. After World War II, many soldiers received an opportunity to live on their property in a single-family home, resulting in a baby boom and a surge in demand for tract houses. Seventy-seven million children had been born by the end of 1964. At that time, the suburbs were booming, with over a third of the population residing there. 

The American Road Trip

Cars turned into a symbol of personal freedom and independence, allowing us to travel throughout the nation at will. For many families, the famous American road trip is a ritual. The destination itself, often overlooked, holds little value, as that feeling of liberty and the ability to travel to any desired location in the country alongside your family and friends is what brings immense joy. The complex infrastructure designed around your car makes this activity even better.

New Business Categories

Many new businesses started along with the development of automobiles. Getting hungry in the middle of the trip stopped being a problem. Just hit the local drive-in or drive-thru where carhops, sometimes on roller skates, will take care of the food orders, letting you stay inside the car. After everyone is full and satisfied, the desire to watch a good movie kicks in. So, our next destination is the drive-in theater. This gigantic outdoor screen with a parking area next to it was popular in the 1950s, romanticized by TV series such as Happy Days, American Graffiti, and Grease. Once again, there was no need to leave the vehicle unless you wanted to get some snacks from the concession stand. On the way home, let’s stop at a mall for some shopping. It is convenient to have many different stores gathered for us in one place. However, the distance from the downtown is reasonable. That is why we have cars; otherwise, such shopping centers wouldn’t exist. 

Hot Rodding, Drag Racing, and NASCAR

Coming back home from a heartwarming, peaceful family trip, it feels like there is a need for something more out of your car. What if it could go faster? Solely add an enormous engine and get a fancy paint job, turning it into a hot rod. Hot rodding and drag racing are motorsports that gained popularity in the 1950s and remain relevant. Another is NASCAR, where racers compete on slightly tilted speedways using stock cars. It is, by the way, the second most spectated sport in the USA behind the NFL (National Football League).

We could write a book on the tremendous impact cars made on American culture and society. However, a piece of paper could never fully convey all the experiences, as every automobile becomes unique in our hands. At Tempus Logix, we offer auto transportation across the nation, no matter if it is a hot rod, a family van, or a tractor: so that your motor vehicle can always stay by your side.

American popular music has had a profound effect on music across the world. The country has seen the rise of popular styles that have had a significant influence on global culture, including ragtime, blues, jazz, swing, rock, bluegrass, country, R&B, doo wop, gospel, soul, funk, punk, disco, house, techno, salsa, grunge and hip hop. In addition, the American music industry is quite diverse, supporting a number of regional styles such as zydeco, klezmer and slack-key.

Distinctive styles of American popular music emerged early in the 19th century, and in the 20th century the American music industry developed a series of new forms of music, using elements of blues and other genres of American folk music. These popular styles included country, R&B, jazz and rock. The 1960s and 1970s saw a number of important changes in American popular music, including the development of a number of new styles, such as heavy metal, punk, soul, and hip hop. Though these styles were not in the sense of mainstream, they were commercially recorded and are thus examples of popular music as opposed to folk or classical music.

Queen Anne homes were popularized in the later Victorian era, beginning around 1880. This style is the quintessential Victorian home for many, with ornate woodworking and decor inside and out.

Queen Anne homes have key regional differences across the country, but maintain these essentials:

• Textured walls with decorative shingles or half-timbering
• Large round or polygonal tower at the home’s corner
• Steeply pitched and asymmetrical roof
• Decorative spindles on porches and trim
• Decorative single-pane or stained glass windows

Queen Anne architecture is most common in homes, but can also be seen in schools, churches, and office buildings.

The Royal Exchange in London was founded in the 16th century by the merchant Sir Thomas Gresham on the suggestion of his factor Richard Clough to act as a centre of commerce for the City of London.[1] The site was provided by the City of London Corporation and the Worshipful Company of Mercers, who still jointly own the freehold. It is trapezoidal in shape and is flanked by Cornhill and Threadneedle Street, which converge at Bank junction in the heart of the city. It lies in the ward of Cornhill.

It has twice been destroyed by fire and subsequently rebuilt. The present building was designed by Sir William Tite in the 1840s. The site was notably occupied by the Lloyd's insurance market for nearly 150 years. Today the Royal Exchange contains Fortnum & Mason The Bar & Restaurant, luxury shops, and offices.

Traditionally, the steps of the Royal Exchange are the place where certain royal proclamations (such as the dissolution of parliament) are read out by either a herald or a crier. Following the death or abdication of a monarch and the confirmation of the next monarch's accession to the throne by the Accession Council, the Royal Exchange Building is one of the locations where a herald proclaims the new monarch's reign to the public.

Gothic Revival architecture grew in the mid-19th century and was one of the early styles of Victorian-era homes. The Gothic Revival style takes influence from Medieval Europe and was designed as a country home. Architects believed the asymmetrical design and ornamentation complemented the nature of rural America.

Gothic Revival homes can be identified by their:

• Pointed arch in windows, doors, and decoration
• Elaborate wood trim vergeboards and bargeboards
• Steeply pitched roofs and front-facing gables
• Towers and turrets resembling medieval castles

Gothic Revival architecture was a popular style for schools and churches as well as rural homes.
