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]

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.
Townhomes are common in cities and densely populated neighborhoods. Townhouses are tall and narrow homes designed to make the most out of vertical space without too much of a yard or garden area.
Homes are considered townhouses when they:
- Share one or two walls with adjacent homes
- Have their own entrances
- Are built with multiple floors to maximize vertical space
- Often share a similar style to their neighbors’ homes and may operate under an HOA
Townhouses can be built to mimic other architecture styles, like Italianate and Greek Revival, while maintaining the condensed, vertical floor plan.
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.

Georgian-style homes were one of the most common styles in the 18th century and showcased formal and classical details that previous homes didn’t. Georgian houses are similar to Federal houses, though they can be distinguished by:
- A crown and pilasters framing the front door
- Decorative quoins or bricks at the corners
- Smooth decorative blocks as moulding
You can also find regional variations with hooded front doors and pent roofs between levels.
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.
Modern Tudor homes are inspired by Medieval European Tudor homes and often have a charming cottage aesthetic. They’re popular on the East Coast and in parts of the Midwest.
Tudor homes are an easy style to identify. They feature:
- Steeply pitched gable roofs
- Exposed and decorative half-timbering with stucco exterior
- Mixed-material brick or stone walls
- Casement windows in groups or with diamond shapes
The Tudor Revival reached peak popularity in the 1920s and is still widely popular today.
Second Empire homes were a modern Victorian-era style that started in France before spreading through the Northeastern and Midwestern United States. Second Empire architecture features similar ornate Victorian trends, though generally offers a simplified Victorian aesthetic.
These elements help identify a Second Empire home:
- Uniquely shaped Mansard Roof
- Decorative window framing and dormers
- Decorative rails or balustrades around terraces and staircases
- Iron roof crest and eaves with support brackets
Second Empire homes are also easy to identify since they’re the only Victorian-era style that often features a symmetrical, rectangular floor plan.
