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.

The U.S. health system is a mix of public and private, for-profit and nonprofit insurers and health care providers. The federal government provides funding for the national Medicare program for adults age 65 and older and some people with disabilities as well as for various programs for veterans and low-income people, including Medicaid and the Children’s Health Insurance Program. States manage and pay for aspects of local coverage and the safety net. Private insurance, the dominant form of coverage, is provided primarily by employers. The uninsured rate, 8.5 percent of the population, is down from 16 percent in 2010, the year that the landmark Affordable Care Act became law. Public and private insurers set their own benefit packages and cost-sharing structures, within federal and state regulations.
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.
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.
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 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.



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]

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.

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.

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.”

The Parthenon in Centennial Park, in Nashville, Tennessee, is a full-scale replica of the original Parthenon in Athens. It was designed by architect William Crawford Smith and built in 1897 as part of the Tennessee Centennial Exposition.
Today the Parthenon, which functions as an art museum, stands as the centerpiece of Centennial Park, a large public park just west of downtown Nashville. Alan LeQuire's 1990 re-creation of the Athena Parthenos statue in the naos (the east room of the main hall) is the focus of the Parthenon just as it was in ancient Greece. Since the building is complete and its decorations were polychromed (painted in colors) as close to the presumed original as possible, this replica of the original Parthenon in Athens serves as a monument to what is considered the pinnacle of classical architecture. The plaster replicas of the Parthenon Marbles found in the Treasury Room (the west room of the main hall) are direct casts of the original sculptures which adorned the pediments of the Athenian Parthenon, dating back to 438 BC. The surviving originals are housed in the British Museum in London and at the Acropolis Museum in Athens.
