George Washington

America’s first president had no guidebook to follow, so George Washington ended up writing the first chapters of the office himself. With calm judgment and a focus on fairness, he set the tradition of serving only two terms, showing that leadership should be about duty rather than personal power.

Washington organized the very first Cabinet, established the tone for presidential addresses, and worked hard to promote unity among different regions and viewpoints. His steady approach helped turn a young, uncertain nation into a stable and functioning republic. The patterns he created became the model for every subsequent president.

James Madison

Often called the "Father of the Constitution," James Madison helped shape the foundations of the United States long before he stepped into the presidency. He played a central role in writing the Constitution and co-authored the Federalist Papers, a series of essays that explained how the new government was meant to work.

Once in office, Madison continued to support the development of stronger federal systems that could serve a growing country, and he oversaw the admission of new states into the expanding Union. His steady leadership helped reinforce the structure laid down by the founders and proved that the nation’s early ideas—balance, stability, and cooperation—could stand the test of time.

Abraham Lincoln

The 16th U.S. president guided the nation through a time of deep division with a calm, steady determination and a clear sense of purpose. He held firmly to the belief that all people are created equal, and he worked to bring those principles to life in practical, lasting ways.

During his presidency, Lincoln supported major constitutional changes that broadened personal freedoms and strengthened the role of the federal government in protecting those rights. He emphasized unity, fairness, and the idea that the country could emerge stronger if it stayed true to its core values. His dedication to these ideals has made him one of the most admired figures in American history, remembered for his integrity and his hope for a more united nation.

Theodore Roosevelt was known for his enthusiasm, his adventurous spirit, and his deep love of the outdoors. He became one of the nation’s strongest voices for conservation, helping to create and expand national parks, forests, and wildlife areas.

His domestic program, the "Square Deal," aimed to make sure consumers, workers, and businesses were treated fairly, and he pushed for stronger rules that protected everyday Americans from unfair practices. Roosevelt also encouraged the nation to step forward with confidence, backing improvements in transportation and modern infrastructure that helped connect the United States more smoothly with the world.

Woodrow Wilson

Woodrow Wilson arrived in Washington with a plan to give everyday Americans a fairer, more balanced system, and his wave of domestic reforms—known as the "New Freedom"—reflected that goal. During his presidency, the nation saw the creation of the Federal Reserve System and the Federal Trade Commission, two major institutions designed to keep the economy steady and well-regulated.

Wilson also encouraged the idea that countries should work together through organized cooperation rather than standing apart, a view that later influenced the formation of important international organizations. His belief in self-determination and his preference for diplomacy over isolation helped guide the United States toward a long-term vision of global partnership and shared responsibility.

Franklin Roosevelt guided the nation through one of its toughest economic periods with a wide-ranging effort known as the "New Deal." This collection of policies helped support workers, steady the banking system, and strengthen protections for consumers. It also introduced Social Security, a program that quickly became a key element of retirement planning for millions of Americans.

Roosevelt understood the importance of keeping the public informed, so he spoke directly to families through his regular radio broadcasts, the famous "Fireside Chats." In these simple, calm conversations, he explained what the government was doing and why, helping people feel more confident in uncertain times. His clear, steady communication made him one of the most trusted and familiar voices of his era.

When Harry Truman took office in 1945, both the world and the United States were undergoing a period of rapid change. With a practical mindset, the 33rd president helped launch broad programs aimed at rebuilding European economies and encouraging stronger international cooperation.

He also set a new long-range direction for American policy, one that emphasized stability, democratic principles, and economic support beyond U.S. borders. Truman’s meaningful efforts helped shape how nations worked together and signaled the beginning of important social changes that would continue to unfold in the decades ahead.

John F. Kennedy brought a fresh sense of youth and optimism to the early 1960s. His speeches often called on Americans to lend a hand, serve their communities, and think beyond themselves—captured in his well-known line, "Ask not what your country can do for you, ask what you can do for your country."

Kennedy supported important civil rights efforts and encouraged steady progress in science and technology. He also pushed the nation to look toward the future through expanded space exploration and created the Peace Corps, giving young Americans opportunities to volunteer and make a difference overseas. His steady promotion of learning, service, and innovation helped spark a spirit of national progress that defined much of the decade.

Lyndon Johnson arrived in the White House with a far-reaching plan he called the "Great Society," a vision aimed at improving everyday life for people across the country. Under his leadership, Congress passed major civil rights legislation that strengthened equality and safeguarded voting rights, setting new standards for fairness.

The 36th president also approved the creation of Medicare and Medicaid, programs that gave millions of older adults and low-income families reliable access to health care for the very first time. Additionally, he supported initiatives to improve education, preserve natural resources, and strengthen local communities.

Ronald Reagan stepped into the 1980s carrying a message of confidence and renewal, offering Americans a sense of fresh direction after a challenging period. His economic approach—later known as "Reaganomics"—was centered on lowering taxes, easing federal regulations, and giving businesses more room to grow. For many people, this era became associated with rising optimism.

Reagan also spoke often about national pride and traditional values, presenting a steady, recognizable voice on the world stage. His leadership style—straightforward, good-humored, and easy to understand—left a lasting mark on how political ideas were discussed and helped shape the country’s tone for years to follow.

Computer viruses not only make files disappear but also create files and folders to disguise their presence. Some viruses modify files on a computer by giving them almost identical names, allowing them to blend in with the rest of the documents.

10

Disabled security tools

Image: Ed Hardie

Antivirus programs and security tools are some of our best allies against computer viruses. That’s why, when a virus infects a computer, it often disables security features to make its job easier. Some viruses are specifically designed to disable security tools, giving them access to the computer’s data and private information. If an antivirus program has been disabled, it could be a sign that a virus has shut it down.

American Goldfinch

If you’ve spotted a drop of sunshine landing on your feeder sometime in the summer, that’s the American Goldfinch. Males turn a vivid yellow each year thanks to a complete molt, usually finished by late May.

They’re found coast-to-coast but are especially common in the northern and central U.S., where they favor open meadows and backyard thistle feeders. Unlike most songbirds, they nest late, often waiting until July when thistle seeds peak. If you see a tiny bird—barely 5 inches long—bouncing through the air in a roller-coaster flight pattern, you’ve found the American Goldfinch.

2

Blue Jay

Blue Jays are known for being loud, confident, and colorful. Throughout the eastern half of the U.S., from Florida to Maine, they flash electric-blue wings marked with black "bar codes." Their blue color is actually a light trick: microscopic feather structures scatter wavelengths to create the hue. Another fun fact: back in the 1970s, researchers discovered they can mimic hawks, a clever way to scare other birds away from food.

3

American Robin

Long before digital calendars, people guessed the seasons thanks to this bird. The American Robin’s spring chorus has been recorded in journals as early as the 1800s, marking the end of winter across most of the U.S. They’re widespread, found in all lower 48 states and even in Alaska during summer. Robins stand upright, tugging worms from lawns with that unmistakable rusty-orange chest. Adults measure about 10 inches long, roughly the size of a small paperback book.

4

Ruby-Throated Hummingbird

If you’ve ever seen a green flash zip past your porch faster than a camera shutter, it may have been a Ruby-throated Hummingbird. It is the only hummingbird species that breeds east of the Mississippi. It weighs 0.2 ounces—as little as a nickel!—yet crosses the Gulf of Mexico during migration. Males display an iridescent red throat that lights up when sunlight hits at the perfect angle. A single feeder with a simple sugar solution can lure them in from May through September.

5

Northern Cardinal

Northern Cardinals look like Christmas on wings, and it’s easy to see why. Males glow bright red, while females wear warm browns brushed with hints of red. They live year-round in the eastern and central U.S., especially in woodlots and suburban yards. Cardinals measure about 9 inches long and crack seeds with thick, powerful bills. Their "what-cheer!" call is one of the most recognized bird sounds in North America.

6

Song Sparrow

At first glance, this little brown bird might look like one of many, but listen closely. Song Sparrows have been studied for their remarkable vocal variety; a single male may sing more than 10 distinct song types. They’re common nationwide, from the Atlantic to the Pacific, but differ subtly by region. They’re small—around 6 inches—but their voice carries surprisingly far.

7

Black-Capped Chickadee

A bird the size of a tennis ball—about 0.3 ounces—with the confidence of a much larger creature: that’s the Black-capped Chickadee. They have a surprisingly sophisticated communication system. In fact, biologists discovered that the number of "dee" notes in their call changes depending on the threat level of predators.

Found across the northern U.S. and in the Rockies and Appalachians, they sport crisp black caps and snow-white cheeks. Offer sunflower seeds, and they’ll visit you all winter.

8

Northern Mockingbird

What if one bird could perform an entire playlist? Northern Mockingbirds—common throughout the South, Midwest, and many western suburbs— can mimic over 100 sounds, from other birds to squeaky gates. In the 1960s, scientists confirmed their habit of singing at night, especially males guarding territory.

They’re roughly 10 inches long, the size of a stretched-out flashlight. Their slender gray bodies and white wings make them easy to spot when they swoop from fence posts.

9

Baltimore Oriole

The Baltimore Oriole can be described as "a flame carried by wings", since males sport brilliant orange while females show softer yellows.

These bright orange migrants breed across the Northeast and Midwest before wintering in Central America. Their hanging pouch nests—up to 8 inches deep—are woven with fibers like tiny hammocks swaying in the breeze. Orioles love tall shade trees and can hang upside down to sip nectar or jelly.

10

American Crow

Think of crows as neighborhood detectives. Studies show they can recognize human faces and remember them for years. Found in every U.S. state except Hawaii, American Crows are large—about 17 inches long—and solid black from bill to tail. Their aerial circling and communal roosts, sometimes numbering thousands, are especially common in the Midwest. They travel in family groups and announce their presence with a clear "caw!"

11

Black-billed Magpie

If you’ve ever driven through the Rockies or the Great Plains, you’ve likely seen this striking bird swooping low over fields. Black-billed Magpies, common from Nevada to the Dakotas, wear glossy black feathers with a blue-green sheen and long tails that can reach 12 inches—nearly half their total length. Their dome-shaped stick nests can be 3 feet across, and they thrive in open country and ranchlands.

12

Tufted Titmouse

One of the most charming feeder visitors in the eastern U.S., the Tufted Titmouse has a soft gray coat, a tiny crest, and warm orange patches under the wings. Though small—around 6.5 inches—they have a bold, ringing call: peter-peter-peter . Their range has expanded steadily northward, partly thanks to backyard feeders. Another fun fact: titmice store seeds one by one in tree bark, creating "pantries" they revisit all winter.
