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]

There was a renewed interest in handcrafted art and design following the industrial revolution. This became the “Arts and Crafts” era and paved the way for the Craftsman home, or “arts and crafts” home.
Craftsman homes focus on simplicity to counter the ornate stylings of Victorian homes. They’re also designed to highlight the craftsmanship of its builders and include:
- A low-pitched roof with overhanging eaves
- A covered porch
- Woodwork including exposed beams and built-in features like shelving
- Natural tones to complement the warmth from woodworking
Craftsman homes are favored for their character and are another versatile style that may borrow common elements from other home styles.
Shingle-style homes took influence from Colonial architecture rather than Medieval Europe. Ornamentation became simpler towards the end of the Victorian-era and Shingle-style homes are best known for their creative floor plans and signature shingles on exterior walls.
Shingle Victorian homes are identified by these interior and exterior features:
- Shingles cover the entire exterior
- Asymmetrical interior layouts without a central hallway
- Emphasis on horizontal planes
- Custom built to meld with the nature surrounding the house
Shingle-style houses were designed as a work of art and encouraged creativity in their use of shapes and features.
House styles will continue to evolve with influences from history, culture, and our lifestyles. All of these house styles can be seen and celebrated across the US and have their own stories to tell. Choose the house style that fits your lifestyle, location, and, of course, personal style best. Then check your credit score, get pre-approved, and start house-hunting.
Cape Cod homes are similar to the British or American Colonial homes, though they originated further north in Cape Cod, Massachusetts. These are often seen as the classic American family home since the style’s revival in the 20th Century.
Cape Cod homes are identified by their:
- Shingle exteriors
- Modest size and ornamentation compared to British Colonial homes
- Originally single-story homes
- Large central fireplaces
- Attic lofts (20th-century revival)
- Dormer windows (20th-century revival)
Cape Cod homes are built of local wood and stone to withstand the north-eastern weather. This exterior weathering provides an iconic weathered-blue color to these homes.
Mid-century Modern designs are nothing new and have influenced interior design, graphic art, and house styles. Mid-century Modern homes are designed to embrace minimalism and nature. They’re also often modeled to appeal to a futuristic or abstract concept.
Mid-century Modern homes can be identified by their:
- Flat planes and clean lines
- Monochromatic brickwork
- Asymmetrical home layouts
- Nature-inspired interior
- Interior level shifts between rooms
Mid-century architecture is still widely popular today, as are Mid-century Modern interior design and furniture trends.
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.
The American Academy of Arts and Sciences (abbreviation: AAA&S) is one of the oldest learned societies in the United States. It was founded in 1780 during the American Revolution by John Adams, John Hancock, James Bowdoin,[1] Andrew Oliver, and other Founding Fathers of the United States.[2] It is headquartered in Cambridge, Massachusetts.
Membership in the academy is achieved through a thorough petition, review, and election process.[3] The academy's quarterly journal, Dædalus, is published by MIT Press on behalf of the academy.[4] The academy also conducts multidisciplinary public policy research.
The Academy was established by the Massachusetts legislature on May 4, 1780, charted in order "to cultivate every art and science which may tend to advance the interest, honor, dignity, and happiness of a free, independent, and virtuous people."[6] The sixty-two incorporating fellows represented varying interests and high standing in the political, professional, and commercial sectors of the state. The first class of new members, chosen by the Academy in 1781, included Benjamin Franklin and George Washington as well as several international honorary members. The initial volume of Academy Memoirs appeared in 1785, and the Proceedings followed in 1846. In the 1950s, the Academy launched its journal Daedalus, reflecting its commitment to a broader intellectual and socially-oriented program.[7]
Since the second half of the twentieth century, independent research has become a central focus of the Academy. In the late 1950s, arms control emerged as one of its signature concerns. The Academy also served as the catalyst in establishing the National Humanities Center in North Carolina. In the late 1990s, the Academy developed a new strategic plan, focusing on four major areas: science, technology, and global security; social policy and education; humanities and culture; and education. In 2002, the Academy established a visiting scholars program in association with Harvard University. More than 75 academic institutions from across the country have become Affiliates of the Academy to support this program and other Academy initiatives.[8]
The Academy has sponsored a number of awards and prizes,[9] throughout its history and has offered opportunities for fellowships and visiting scholars at the Academy.[10]
In July 2013, the Boston Globe exposed then president Leslie Berlowitz for falsifying her credentials, faking a doctorate, and consistently mistreating her staff.[11] Berlowitz subsequently resigned.
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 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.
Modern home design became popular in the early 20th century and has a heavy influence on today’s contemporary designs. The core of modern designs can be seen in their:
- Use of geometric shapes
- Large, floor-to-ceiling windows
- Clean lines and flat roofs
- Open floor plans
These styles attempt to connect with nature through minimalism and fluid design between outdoor and indoor spaces. Modern house styles branch into a few key sub-styles.
Cottage-style homes are often quaint and cozy — emphasizing charm and comfort over ornamentation. Cottage houses come in a variety of styles and can mimic bungalows, Tudor house styles, and more.
Look for these designs to identify a cottage:
- Asymmetrical exterior
- Typically one to one-and-a-half stories
- Traditional aesthetics that aren’t too rustic
- Open floor plans with wide halls and doorways
A cottage house style is extremely versatile, and its small size makes it great for small families or guest houses.
