The United States has an area of 3.79 million square miles (9.83 million kilometers) and a population of more than 303 million people, making it the third or fourth largest country by total area, and third largest by land area and by population. The United States is one of the world’s most ethnically diverse nations.

Are Machines making human a dumb?

Imagine being surrounded by technologies, and hardly being aware of them. For instance, a person walks into a room and without doing anything, the entire atmosphere is fine-tuned to his or her current mood or expectations. Measurements are taken, personal data is sensed and recorded, and the room adjusts to integrate with the person’s countenance. All this occurs without turning a switch or adjusting an appliance simply walk into the room. We’re beginning to move in this direction, with recent advances in medical technology, with personal fitness devices, and with smart home systems.

Behind the scenes, as the individual enters the room, the unseen technology helps advance the person’s security, health, comfort, and even creativity by providing a seamless set of adjustments and changes to everything from room temperature to computer access to food preparation. What’s not seen are the computers running super-high-speed algorithms, computations, and calculations processing commands and actions to create a seamless life existence for everyday needs.

Here’s a real-world scenario: The person walks in the room. The sensors identify the person, as well as the mood of the person using facial features and expressions, body temperature, and movements, including gait and posture. Additionally, the smart room can monitor an individual’s current health conditions, such as blood pressure, heart rate, breathing, and chemical composition. This is all done in real time.

Next, a robot comes out bringing you water and vitamin supplements from sensing those that are physically lacking. While sitting in a couch overlooking a virtually-generated ocean with the sound of crashing waves, the user decides to catch up on what is happening in the world and accesses the latest news by making a quick sweeping gesture in the air. The room instantaneously turns off the ocean scene and pulls up a news program. It all happens without the user needing to be fully aware of the entire process.

Such a scenario isn’t just limited to the confines of a person’s living quarters. It can apply to a city, a park, a museum, or a business. Imagine a society that’s so intelligent that the machines and computers are constantly collecting data, and learning from our actions and behaviors to make sound judgements and decisions. This human centric vision is just that, centered on the individual with technology serving to enhance, nurture, and protect, making life continually easier, healthier, and more productive. Importantly, people will retain and use the power to preprogram myriad commands and conditions suitable for their daily lifestyles and activities.

Are these innovative technologies are “dumbing” ground for your kids future?

What should I do if I find a gun?

Studies have shown that hundreds, perhaps even thousands, of children and teenagers are accidentally killed by guns in the United States each year. Millions of American kids have access to guns in their homes. People use guns all the time in movies and television shows, and the action scenes in these shows make guns look exciting and powerful. What these shows can’t really convey is the massive, painful destruction an exploding bullet causes when it hits a person’s body. While many kids understand that, in real life, guns can be very dangerous and can cause great harm, most still find guns fascinating. If an adult is supervising and your parents have given their approval, it’s okay to look at and even touch an unloaded gun. But if you are alone or with other kids and you come across a gun, remember that it is not a toy and should not be handled. Guns should never be pointed at another person, even if you intend it as a joke.

If you find a gun in your own house, a friend’s house, or elsewhere, as tempting as it might be to play with it, remember the damage that guns can cause and leave it alone. If you’re away from home, leave right away and tell your parents what happened. Your parents may be upset and worried that you found a gun, but they will be very glad that you told them about it because then they can help you stay safe.

What is an estuary?

Estuaries are bodies of water along the beaches that are formed when freshwater from rivers flows into and mixes with saltwater from the ocean. Tides may rise and fall in the estuary, making this area a unique ecosystem rich in nutrients. Only certain types of plants, such as saltwort, eelgrass, and saltgrass can grow there, and few animals can live their entire lives there. However, mud shrimp, certain types of mussels, and the Western sandpiper all call estuaries home.

Why does a ball bounce upon falling?

When a ball falls, it is temporarily deformed. Because of elasticity, the ball tends to regain its original shape for which it presses the ground and bounces up (Newton’s Third Law of Motion).

Why do we say a corrupt person has “gone to the Devil”?

In Victorian times, to “go to The Devil” was to visit a bar on Flat Street near the London Civil Courts. The Devil was a favourite pub for lawyers, who seemed to spend more time in that bar than in their offices. If a client thought his money had “gone to The Devil” to pay for his lawyer’s drinks, he might visit the legal offices to ask for an explanation, where he would be told that the absent lawyer had indeed “gone to The Devil.”

Will people live in space one day?

Many films and science-fiction books have shown colonies of humans living on the Moon or Mars, but at this time it is still a distant possibility. Since the 1960s, NASA has been planning lunar bases to use for scientific study or for training astronauts to go to Mars. Space stations have been designed to keep astronauts as comfortable as possible, with a 70 degrees Fahrenheit (21 degrees Celsius) constant temperature and all of the freeze-dried food, exercise equipment, and other amenities necessary for short-term life in space. However, only some people can actually adapt to a life in space, which includes a weightless environment, living in close quarters, and using technology necessary for carrying out routine daily activities. While it is possible for a scientific community to be functioning in space by the year 2020, it is less likely that the average citizen will be able to permanently relocate there anytime soon.

Which animal is both the biggest mammal and the largest living creature on Earth?

The blue whale, who swims all of the world’s oceans, in the largest mammal. The largest blue whale cited was at least 110 feet (33.5 meters) long and weighed 209 tons (189,604 kilograms). The average length is about 82 feet (25 meters) for the males, and 85 feet (26 meters) for the females. A newborn blue whale can weigh anywhere from 2.5 to 4 tons (2,268 to 3,628 kilograms), and can reach 100 to 120 tons in adulthood. Whale calves drink 50 to 150 gallons of its mother’s milk per day, adding about 8 pounds (3.6 kilograms) of weight per hour, or 200 pounds (90.7 kilograms) per day.

At about eight months of age, when the calf is weaned, it measures close to 50 feet (15.2 meters) long and weighs about 25 tons (22,679 kilograms). Blue whales do not have teeth. Instead, in their upper jaw they have rows of hundreds of baleen plates—flat, flexible plates with frayed edges, arranged in two parallel rows that look like combs of thick hair. The blue whale feeds on a small shrimp-like animal called krill. Scientists believe that large marine mammals, like whales and dolphins, have brains much like those of humans. They are able to communicate, follow instructions, and adapt to new environments. Throughout history, these gentle giants have been hunted for their baleen and blubber (fat), and are today considered an endangered species. Scientists believe there are about 4,000 or so of them left in the world.
