1 . Maclay Summer Day Camp

The Maclay Summer Day Camp will once again provide a lot of activities. Camp hours are from 8:30 am to 3:00 pm. This camp is fun as well as meaningful.

Morning activities will include computer games, swimming, kickball, arts & crafts, relay races, swimming, and many more. All of these morning activities will be organized on Maclay’s 100-acre (英亩) campus. Maclay has its own gymnasium, locker rooms, swimming pool, dining hall, and transportation.

Campers will be transported to all afternoon activities off campus by a Maclay school bus.

The $230.00 a week tuition (学费) covers all costs, lunches, admissions (入场费), etc. However, it does not cover the cost of additional items (snacks from movies, games from Skate World, etc.)

A snack will be provided by the camp each morning and lunch will be provided at noon in the Maclay Dining Hall.

2 . A CLEAN, GREEN ENERGY FUTURE

Nowadays, many countries are making the important change from fossil fuels to clean, green and renewable sources of energy. Fossil fuels produce emissions, but renewable energy sources cause limited damage to the environment.

Here are the main types of renewable energy, with facts and examples from around the world.

Solar

Solar panels turn heat from the sun’s rays into electricity, and solar heaters use that energy to heat water directly. Germany has the highest solar capacity in the world, but China is the world’s largest market and the largest producer of solar technology.

Hydropower

The power of water turns turbines which produce electricity. Since ancient times, watermills have been used a lot. Most of the renewable energy in China comes from hydropower plants, such as the Three Gorges Dam, the world’s largest power station.

Geothermal

This has been a natural source of energy for thousands of years. Today, heat from below the earth’s surface heats water into steam that turns turbines to generate electricity. The USA has the largest capacity, with over 80% generated in California. The Yangbajing Power Plant is the largest geothermal plant in China.

Wind

Tall turbines are turned by the wind to produce electricity. Wind “farms” are built on land, or offshore, to take advantage of more frequent and powerful winds at sea. The world’s largest wind farm is the London Array. It has 175 wind turbines and is 20 km off the coast of England. Researchers think China could meet all her electricity demands from wind by 2030. Wind farms in provinces such as Gansu have an endless wind supply.

3 . Early in my career, I was easily overwhelmed. My responsibilities, commitments and ambitions piled up into this mass that I felt immeasurably large—until, one day, when I worked in federal contracting, my manager gave me something that is still on the bulletin board over my desk 26 years later, even as I’ve now transformed my career: It’s a postcard picture of Earth.

He wanted me to look at Earth and think about the significance of what I was trying to accomplish, and the stress I was feeling, and to do so in the context of what others around the world faced. I started to do this during late nights in my office, when I hadn’t seen my family in days, as I lived on caffeine and cheese nabs. I imagined the good happening to people around the globe. I also imagined the bad—people starving, enduring war, or losing their homes—and then weighed my situation. I would say a prayer for them, and I would remember that my time on Earth was limited.

With this perspective and my manager’s encouragement, I went back to school, then took a job with a Fortune 500 firm as a contracts manager and rose to become a director and VP. I have recently started my own consulting business to mentor small companies entering federal contracting. I’ve found that many folks feel they must make a good impression or prove themselves, and that to do so, they cannot admit when they need help. But I can see it in their eyes or hear it in their voices. I tell them what my manager told me: Step away for a few minutes, prioritize your actions, and focus on what your best can be in that moment.

That is how I hope to make a difference in their lives. And who knows, maybe beyond what I see, my presence ripples (传开) out to their circles of influence, which reaches others’— creating waves again to those that make up all that blue in my picture of Earth.

4 . 4 brilliant hybrid bikes for urban or off-road use

6 . The following are some of the most recognizable names in art history.

Leonardo da Vinci

Leonardo da Vinci, born in 1452 in Tuscany, Italy, was a genius. His one-of-a-kind gift was expressing human emotions, which earned him a name from an early age. He kept painting until his death in France in 1519. His Mona Lisa is a painting that was originally left incomplete but has become the world’s most famous picture.

Vincent van Gogh

Vincent van Gogh, born in the Netherlands in 1853, is widely regarded as one of the finest post - impressionist painters of all time. He did not become an artist until he was in his late twenties. In 1886, he traveled to Paris, where he met Paul Gauguin, who encouraged Van Gogh to develop his own style. He died in 1890 after suffering from mental health problems. Van Gogh became famous after his death.

Claude Monet

Claude Monet, born in Paris in 1840, was a talented French artist who is widely considered as one of the most important painters. He was recognized for his talents when he was young and he was the first to employ oil and outdoor methods. The word “impressionism” was created after his picture Impression, Sunrise. Monet died at age 86.

Pablo Picasso

Pablo Picasso was born in Malaga, Spain, in late 1881. He began drawing at a young age and had gotten his first lessons in the use of oil paints from his father by the time he was seven. In 1900, he moved to Paris and sold his first painting there. He made significant contributions to the progress of modern art. He passed away in 1973.

7 . When people hear “artificial intelligence,” many envision “big data.” There’s a reason for that: some of the most important AI breakthroughs in the past decade have relied on enormous data sets. But AI is not only about large data sets, and research in “small data” approaches has grown extensively over the past decade—with so-called transfer learning as an especially promising example. Also known as “fine-tuning,” transfer learning is helpful in settings where you have little data on the task of interest but abundant data on a related problem. The way it works is that you first train a model using a big data set and then retrain slightly using a smaller data set related to your specific problem.

Research in transfer learning approaches has grown impressively over the past 10 years. In a new report for Georgetown University’s Center for Security and Emerging Technology (CSET), we examined current and projected progress in scientific research across “small data” approaches. Our analysis found that transfer learning stands out as a category that has experienced the most consistent and highest research growth on average since 2010. This growth has even outpaced the larger and more established field of reinforcement learning, which in recent years has attracted widespread attention.

Small data approaches such as transfer learning offer numerous advantages over more data-intensive methods. By enabling the use of AI with less data, they can bolster progress in areas where little or no data exist, such as in forecasting natural disasters that occur relatively rarely or in predicting the risk of disease for a population set that does not have digital health records.

Another way of thinking about the value of transfer learning is in terms of generalization. A recurring challenge in the use of AI is that models need to “generalize” beyond their training data. Because transfer learning models work by transferring knowledge from one task to another, they are very helpful in improving generalization in the new task, even if only limited data were available.

Moreover, by using pretrained models, transfer learning can speed up training time and could also reduce the amount of computational resources needed to train algorithms (算法). This efficiency is significant, considering that the process of training one large neural (神经系统的) network requires considerable energy.

Despite the growth in research, transfer learning has received relatively little visibility. The existence of techniques such as transfer learning does not seem to have reached the awareness of the broader space of policy makers and business leaders in positions of making important decisions about AI funding and adoption. By acknowledging the success of small data techniques like transfer learning—and distributing resources to support their widespread use—we can help overcome some of the common misconceptions regarding the role of data in AI and facilitate innovation in new directions.
