Article: The oldest and hardest cow beef may be made as tender and tasty as young and choice met. "This declaration was made by the French physicist Denis Papin in book published in 1681, which described his "New Digester" or pressure cooker. It was a cast iron pot with an air-tight lid, which allowed liquids to boil at a higher temperature than usual, and so it cooked food in a quarter of the time. The food was cooked by pressurized steam being forced through it at about 121degC. All pressure cookers were made of cast iron until 1905, when the first aluminum model was made in America. In 1938, Alfred Vischer, a man from Chicago, U. S. A., designed a simple interlocking pan and lid, and an improved pressure-tight seal --a replaceable rubber sealing ring. When Vischer's patent expired in 1954, many companies entered the field, and the rapid pressure cooker became popular with people with people who had little time to cook or had to supply food for unexpected guests.

Article: Started in 1636, Harvard University is the oldest of all the many colleges and universities in the United States. Yale, Princeton, Columbia and Dartmouth were opened soon after Harvard. In the early years, these schools were much alike. Only young men went to college. All the students studied the same subjects, and everyone learned Latin, Greek and Hebrew. Little was known about science then, and one kind of school could teach everything that was known about the world. When the students graduated, most of them became ministers or teachers. In 1782, Harvard started a medical school for young men who wanted to become doctors. Later, lawyers could receive their training in Harvard's law school. In 1825, besides Latin and Greek, Harvard began teaching modern languages, such as French and German. Soon it began teaching American history. As knowledge increased, Harvard and other colleges began to teach many new subjects. Students were allowed to choose the subjects that interested them.

Article: Bedazzling with their bright colors and eye-catching displays, fireworks light up our night skies during the holidays. However, these crowd-pleasers can have some damaging side effects. Once a firework is set off, it only takes a couple of seconds before smoke, dust and harmful chemicals are let out into the atmosphere. The loud booming noises are caused by gunpowder. While the sounds may excite some people, they can be frightening to domestic and wild animals--as well as some humans. The pretty colors you see are a result of more chemicals. Barium, added to make green, is known for its poisonous and radioactive qualities. Blue comes from copper compounds. Cadmium, lithium and lead--all found in fireworks--have been linked to diseases, such as allergies and skin rashes in both humans and animals. Acid rain has been linked to gases given off by fireworks, which sometimes go beyond the toxin limits of the United States Clean Air Act. Once all those chemicals come back down to the ground, they can cause problems too. Debris from the fireworks falls to the ground, where animals can burn their paws or noses on piping hot pieces. Humans also are at risk of stepping on or picking up something sharp or hot. Meanwhile, debris that finds its way into waterways can damage animal habitats and water supply sources. Instead of setting off fireworks, try to come up with some new ways for fun. Here are some ideas to get you started: * Sky lanterns--a tradition that originated long ago in the most-populated Asian country. * Party crackers--a favorite in the United Kingdom--give you noise and surprises without the mess of fireworks. You can make your own or buy eco-friendly crackers. * Want noise excitement with less volume? Consider a fireworks sound recording beforehand or break out the party horns and blow up a storm!
Answer: debris from fireworks can even find its way into water
