In the past, cell phones were big and heavy. In the future, telephones will still be big. The good news is that people will be able to fold them in half to make them smaller. The “foldable phone" is now in development.
One company has come up with a smartphone and tablet in one. This device can fold down to the size of a regular cellphone to make it “pocket-size.” The foldable phone has a larger screen, keyboard, and high-quality speakers. This makes it easy to use. The flexible display can go from smartphone to tablet just by unfolding it. The interior screen is so big that it can run three different apps at the same time. People can watch a video, talk about it, and browse websites online. There are also two batteries inside the phone - one on each side.
Many companies have been looking for ways to improve smartphones. The foldable phone is unlike anything else that has come before it. This powerful machine is a smartphone, computer, and camera all in one. There is a current race to get foldable phones on the market. But we’ll have to wait and see how well these new smartphones work. If people like them, maybe one day we will be able to fold and even stretch our phone.

In recent years, the development of new technologies and the growth of social media sites have helped rapidly progress the global citizenship movement. The impact of this growing phenomenon on higher education is palpable, with more students than ever (23) ______ study abroad and strive to learn more about the world around them. (24) ______ the concept of global citizenship is not a new one, it is becoming ever more important in our expanding and increasingly interconnected world.
Though countless organizations and institutions of higher education cite global citizenship as one of their primary missions, it is imperative that we think about what this term really means. Global citizenship is (25) ______ of several elements, starting with a way of thinking across (26) ______ communities, cultures, and ways of life. While our national identities are assigned to us at birth, a global citizenship takes time to develop, and can only be attained through life experiences. Our interpretation of our experiences, as well as increasing self-awareness, ultimately shapes our ability to become global citizens. This may (27) ______ through a number of activities, from volunteer work in the community to traveling the world.

A large number of inventions require years of arduous research and development before they are perfected. For instance, Thomas Edison had to make more than 1,000 attempts to invent the incandescent light bulb before he finally succeeded. History is replete with numerous other examples of people trying, yet failing to make inventions before they eventually succeeded. Yet some inventions have come about not through hard work but simply by accident.
In most cases, when someone unintentionally invented something, the inventor was attempting to create something else. For example, in the 1930s, chemist Roy Plunkett was attempting to make a new substance that could be used to refrigerate items. He mixed some chemicals together. Then, he put them into a pressurized container and cooled the mixture. By the time his experiment was complete, he had a new invention. It was not a new substance that could be used for refrigeration though. Instead, he had invented Teflon, which is today most commonly used to make nonstick pots and pans. Similarly, decades earlier, John Pemberton was a pharmacist in Atlanta, Georgia. He was attempting to create a tonic that people could use whenever they had headaches. While he was not successful in that endeavor, he managed to invent Coca - Cola, the world - famous carbonated soft drink.
Scientists have also made crucial discoveries by accident when they were conducting experiments. In 1928, Alexander Fleming discovered penicillin, an antibiotic, in this manner. He discovered some mold growing in a dish with some bacteria. He noticed that the bacteria seemed to be avoiding the mold. When he investigated further, he determined some of the many useful properties of penicillin, which has saved millions of lives over the past few decades. Likewise, in 1946, scientist Percy Spencer was conducting an experiment with microwaves. He had a candy bar in his pocket, and he noticed that it suddenly melted. He investigated and learned the reason why that had happened. Soon afterward, he built a device that could utilize microwaves to heat food: the microwave oven.
