Everywhere I look outside my home I see people busy on their high-tech devices, while driving, walking, shopping, even sitting in toilets.

The main goal of technology companies is to get people to spend more money and time on their products, not to actually improve our quality of life. They have successfully created a cultural disease. I see people

After my public lectures on evolution, someone in the audience asks, “Are we still evolving?” People want to know if humans are getting taller, smarter, better looking or more athletic. My answer is truthful but
We’ve seen some evolution in our species over the past few millennia, but it was detected by reconstructing history from DNA sequences. For example, we know that during the past 10,000 years, several populations of humans — those keeping sheep, cows or goats for milk— gained the ability to digest dairy products. This quality was

What started as a race to space between the United States and Russia has turned out to be a technological revolution that has greatly improved the quality of daily life throughout the world. Scientists at the National Aeronautics and Space Administration (NASA) have invented new technology to make space flights doable. The same technology, when applied on Earth, has produced thousands of products in the areas of health and sports that have significant impacts on our lives.
Many of these improvements are in the fields of health and medicine. NASA-inspired technology fueled the great advances in the early detection of deadly diseases. For instance, computer chips designed for the Hubble telescope are used in digital imaging devices that help medical professionals detect cancer at very early stages. Eye doctors can now diagnose vision problems in very young children by using ocular screening. Ultrasound scanners, portable x-ray devices, and bone analyzers are among the medical devices developed with the help of space technology.
Fogless ski goggles and special sportswear are among the hundreds of items of sports equipment inspired by NASA technology. Space technology has been applied to sports too. The running shoes that athletes use today have midsoles that act like shock absorbers and keep the runners steady while in motion. These shoes utilize the technology NASA used to design the moon boot. In golf, athletes use a new ball that employs NASA research on how to make the flight of the ball from the tee to the green faster and more accurate. In swimming, athletes can swim faster because of NASA-developed riblets in the fabric of their swimsuits.
Almost all aspects of daily life continue to improve because NASA scientists are still at work. Transportation, methods of preparing food, and work environments are other ways in which NASA technology has made significant changes.
The Case of the Missing Dinosaur(恐龙)
My little brother Teddy and I run a detective agency together out of an office in my bedroom closet. The sign on the door says Investigations by Nina (with help from Teddy). Well, We’re detectives. We find things like missing shoes and hats.
Teddy handed me notes he’d gathered from the empty flowerpot on our porch(走廊). That’s where family and neighbors let us know about mysteries to solve. I read the papers, only to find that there were nothing important.“ How about a dinosaur?” asked Teddy. “ My friend Peter is missing his dinosaur.” That sounded great. I asked Teddy to tell me everything he knew.
Most days after school, my brother goes across the street to Peter’s house to play Go Fish. But yesterday, Peter refused to play any games. His eyes were red. He kept talking about his dinosaur, Bruno. We decided to help him. Then we walked to Peter’s house to check things out.

The Battle of Chancellorsville, one of the most famous battles of the Civil War, took place in Virginia in the spring of 1863. For months, the two armies had been staying on opposite banks of a narrow river. The Confederate(南方联盟) troops were led by perhaps

In 2000, when I was around seven years old, all my family were coming back from a T-ball game, which was our usual weekend adventure, but unlike every other weekend, a surprise was waiting for us in our driveway—two adult geese and a small goose. Obviously startled by our return, the adults flew away in panic, with their baby, too young to fly, left in place, tiny and delicate.
Hours passed one after another, and night eventually fell. However, with it also came a deep chill and a fear of watchful animals. It was apparent that the gosling needed protection, warmth, and food to make it to the morning, so we had to help it, and we brought him onto our back yard.
We all pretty much slept with one eye open till morning came. And then another morning. And still another. Each morning, we would try to drive the goose away to his parents, who kept coming back to our yard. He wouldn’t go to them, though, and neither would they come close enough to claim him. We kept this up for five days, but no luck. Realizing the young goose had clearly decided we were his family by then, we had to give him a name, calling the little guy Peeper, because he would often follow us around the yard making a peeping(唧唧叫) noise, nonstop. Besides, we decided that Peeper was a boy. I don’t know why; it just felt right.
A year passed and we settled into a routine. Peeper slept on our back yard each night and, in typical goose fashion, used it as a latrine(公共厕所). My dad would spray off all the goose droppings daily. Part of this ceremony included Dad throwing Peeper up into the air so he could flap its wings and flew a loop(圈) around the house, and then came back again once the porch was clean.
Days turned into weeks, and weeks turned into months.
Before we knew it, the little thing had grown into a big bird with two powerful wings.
It came as a total surprise to me when, in 2020, an adult goose made his way back to my family home.
