Article: Researchers are now using 3D printing to create models of the human heart to help heart specialists. The heart doctors can use the models to better help patients before an operation. Dr. Bramlet, a children's heart expert at the University of Illinois College of Medicine, says the 3-D models show information he cannot get any other way. "And so what we've done with the printed models? We've pulled it out of the screen so that you can actually hold it in your hand and evaluate the anatomy ." A 3-D printer uses images from a digital display to create a physical model of a human heart. Matthew Bramlet says doctors can use the model to understand the anatomy. Pictures from medical tests like CAT scan or MRI are sent to a 3-D printer to create a heart in a plaster form. The printer then constructs the heart, thin layer by thin layer. Dr. Bramlet says the model matches the real heart in every detail. "When we're done with the model and made our decision, we want to be able to go back to the source image and confirm those findings," he says. Dr. Bramlet has built model hearts for different kinds of heart operations. All of the operations were successful. In his first case, digital images showed only one tiny hole in a baby's heart. But, the 3-D printed model showed several defects or problems that the baby was born with. Dr. Bramlet says those defects could not be seen easily in the images. The heart surgeon was able to change the type of surgery for the patient based on the 3-D model. He added that 3-D heart models saves time during heart operations. Kathy Magliato is a heart surgeon at Saint John's Health Center in Los Angeles. She welcomes the new technology. She says it could help her make better decisions before she operates on the hearts of her patients. "I can then take this very complicated structure before the operation and I can hold it in my hand and plan an operation around what I'm seeing, touching and feeling. That to me is what can potentially change the game in an operation and save lives." Dr Bramlet continues to research the technology. He is working with the National Institutes of Health to build a 3-D library that includes heart models and images that others can use.

Article: A shopkeeper sent his son to learn about the secret of happiness from the wisest man in the world. The boy walked a long way, and finally came upon the beautiful castle where the wise man lived. On entering the main room of the castle, the boy was quite surprised: tradesmen coming and going, people chatting in the corners, and a small orchestra playing soft music. The wise man talked with everyone, and the boy had to wait for two hours before it was his turn. The wise man listened carefully to the boy's explanation of why he had come, but told him that he didn't have time just then to explain the secret of happiness. He suggested that the boy look around the palace and return in two hours. "Meanwhile, I want to ask you to do something," said the wise man, handing the boy a teaspoon that held two drops of oil. "As you wander around, carry this spoon with you without allowing the oil to spill." The boy began to walk up and down stairs of the palace, keeping his eyes fixed on the spoon. After two hours, he returned to the wise man. "Well," asked the wise man, "Did you see the Persian tapestries in the hall? Did you see the garden that took the master gardener ten years to create?" The boy was embarrassed, and replied that he had observed nothing. His only concern had been not to spill the oil. "Then go back and observe the wonders of my world," said the wise man. The boy picked up the spoon and returned to his exploration of the palace. This time he observed all of the works of art on the ceilings and the walls. When he returned, he described in detail everything he had seen. "But where are the drops of oil?" asked the wise man. Looking down at the spoon he held, the boy saw that the oil was gone. "Well, there is only one piece of advice I can give you," said the wise man. "The secret of happiness is to see all the wonders of the world, and never to forget the drops of oil on the spoon."
Question: When the boy arrived at the castle, he _ .

question:
Article: Davey wanted to play baseball. But fifty years ago, in his small town, he couldn't find enough players for two full teams or an empty lot big enough for a field. And when he played ball in his back yard, he just broke windows and got into trouble. So Davey began playing with a plastic golf ball and a broom handle for a bat. When his dad, David Mullaney, a former semi-pro baseball pitcher , realized his son was hurting his arm trying to throw curves with the little plastic ball, he decided to find a better solution. Mullaney got a bunch of hollow plastic _ from a local factory, sat down at his kitchen table and began cutting different size holes in the balls with a razor knife. He thought maybe the holes would alter the ball's flight and help his son throw curves and sliders without hurting his arm. All the balls failed--except the one with the eight oblong holes cut into one of the hemispheres. This ball curved naturally and sharply without a violent snap of the wrist. In fact, Davey was now striking out so many batters; he called his new ball a "wiffle ball". A year later, Mullaney borrowed $20,000 from family and friends and started producing Wiffle Balls in his little suburban town of Shelton, Connecticut. "I didn't want investors." He said, "I wanted to control my own company." This was the beginning of one of the hottest fads of the fifties and a perennial best seller well known all around the world. Since then millions of boys and girls have enjoyed countless hours of safe, wholesome fun playing with a Wiffle ball and bat. Esquire Magazine has even called the Wiffle Ball "a national treasure". By producing a high quality product at an affordable price, three generations of Mullany's have enjoyed the satisfaction and benefits of running a successful and profitable family business. Over the years, they've had plenty of offers to buy them out, but they're still working out of a small factory in Shelton, making a new Wiffle Ball every couple of seconds. Creativity and persistence are two of the important sources for wealth. If he gave up his attempts at trying new things, Mullany would not have invented the wiffle ball, nor would he have made such a big fortune.
