When I was 17, I read a magazine article about a museum called the McNay, once the home of a watercolorist named Marian McNay. She had requested the community to tum it into a museum upon her death. On a sunny Saturday, Sally and I drove over to the museum. She asked, "Do you have the address? ""No, but I'll recognize it, there was a picture in the magazine. "
"Oh, stop. There it is!” 
The museum was free. We entered, excited. A group of people sitting in the hall stopped talking and stared at us.
"May I help you?" a man asked. "No, "I said. "We're fine.” Tour guides got on my nerves. What if they talked a long time about a painting you weren't that interested in? Sally had gone upstairs. The people in the hall seemed very nosy(爱窥探的), keeping their eyes on me with curiosity. What was their problem? I saw some nice sculptures in one room. Suddenly I sensed a man standing behind me. "Where do you think you are? " he asked. I turned sharply. "The McNay Art Museum!" He smiled, shaking his head. "Sorry, the McNay is on New Braunfels Street." "What’s this place?” I asked, still confused. "Well, it's our home." My heart jolted(震颤). I raced to the staircase and called out, "Sally! Come down immediately! "
"There's some really good stuff(艺术作品）up there." She stepped down, looking confused. I pushed her toward the front door, waving at the family, saying, "Sorry, please forgive us, you have a really nice place." Outside, when I told Sally what happened, she covered her mouth, laughing. She couldn't believe how long they let us look around without saying anything.
The real McNay was splendid, but we felt nervous the whole time we were there. Van Gogh, Picasso. This time, we stayed together, in case anything else unusual happened.
Thirty years later, a woman approached me in a public place. "Excuse me, did you ever enter a residence, long ago, thinking it was the McNay Museum? "
"Yes. But how do you know? We never told anyone. "
"That was my home. I was a teenager sitting in the hall. Before you came over, I never realized what a beautiful place I lived in. I never felt lucky before. You thought it was a museum. My feelings about my home changed after that. I've always wanted to thank you."

There’s a new frontier in 3D printing that’s beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn’t stopping there.
Food production
With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that — it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to “re-create forms and pieces” of food that are “exactly the same,” freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed,rather than farm to table.
Sustainability(可持续性）
The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids (水解胶体) from plentiful renewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.
Nutrition
Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, “Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday’s bread from the supermarket, you’d eat something baked just for you on demand.”
