Most Dutch Colonial homes you find today are actually from the Colonial Revival period of the early 20th Century. Original Dutch Colonial homes feature flared roof eaves and creative wood and brickwork. They are much more ornamental than classic Colonial homes, though the Dutch Colonial Revival style tends to be more subdued than the original Dutch Colonial homes.

Dutch Colonial Revival houses feature:

• Broad gambrel roofs that are visually similar to barn-style roofs
• Open-floor plans
• Flared roof eaves
• Split doors

The large barn-style roofs are the most identifiable feature of a Dutch Colonial home and even became known as “Dutch roofs.”

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.

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.

Around the 1820s, Americans experienced a renewed interest in classic Greek and Roman culture. This cultural shift was a natural fit for architects, who brought the Greek Revival house style to life.

Greek Revival architecture became popular in homes as well as businesses, banks, and churches. Prominent features include:

• Easy to identify shapes, including a rectangular building and triangular roofs
• Gable-front designs
• Large porches and protected entryways
• Greek-inspired columns both square and round

Greek Revival homes often have decorative trim and moulding around the front door and windows. These ornate features and columns are easy ways to identify Greek Revival architecture.

The French Colonial house style can be seen around the world and has significant variety among its sub-styles.

French Colonial houses have the same symmetry as other Colonial homes with these distinct features:

• Dormer windows, including one centered above the door
• External stairs to enter higher floors
• Iron stairs and balconies
• Slightly raised basements to support the floor

French Colonial houses are most similar to Spanish Colonial houses and easily identified by their elaborate iron balconies, stairs, and entrances.

The American Farmhouse is a simple and timeless style. Farmhouses are designed to be practical first and foremost. They’re common across the US and often showcase regional variations, like wrap-around porches in the South.

Farmhouses have evolved with time and location, but often feature these elements:

• Rectangular floor plan
• Large front porches
• Natural wood and stone materials
• Few and small windows
• Formal front rooms separated from family rooms

Of course, the easiest way to identify a farmhouse is that they’ll often be situated on a large plot of farmland.

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.

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]

The Pueblo Revival was inspired by the indigenous Pueblo people’s architecture in the Southwestern US. Pueblo homes were made of adobe or stucco and designed to handle the extreme temperatures of the desert.

Architects in California began to explore the Pueblo style in the late 19th century and the Pueblo Revival style spread across New Mexico, Arizona, and Colorado.

The Pueblo Revival hit its peak in the 1930s in Santa Fe, and these Pueblo-style elements are still popular in the Southwest:

• Rounded corners and irregular shapes
• Earth tones that reflect the desert colors
• Stepped effects with higher floors becoming smaller
• Flat roofs with parapet trim
• Exposed roof beams extending past the walls

The Pueblo Revival style is also commonly called Adobe or Santa Fe style architecture.
