The Evolution of Computers
In the relatively short span of twenty-five years, there has been an incredible evolution in the size and capabilities of computers. Today, computers smaller than the tip of your fingernail have the same capabilities as the room-sized machines of twenty-five years ago. The first computers were developed around 1945. They were so large that they require special air-conditioned rooms. About twenty years later, in the 1960s, desk-sized computers were developed. This represented a gigantic advance. Before the end of that same decade, however, a third generation of computers, which used simple integrated circuits and which were even smaller and faster, had appeared. In 1971, the first microprocessor, less than one square centimeter in size, was developed. Today, electronic engineers predict that even smaller and more sophisticated computers will be on the market before then end of this decade.
A Neutralization Experiment
To perform a neutralization experiment, proceed in the following manner. First, measure out about 2 cc of laboratory NaOH solution. Second, pour the solution into a small casserole. Next, add portions of HC1 solution, stirring after each addition until the solution is acid when tested with litmus paper. Then, place the casserole containing the solution on a wire gauze over a Bunsen burner and heat it until the solution begins to boil. When it does, reduce the size of the flame immediately and allow the solution to boil gently. As it approaches dryness, sputtering may occur. At this point, cover the casserole loosely with a watch-glass. Then, hold the casserole above the flame and move it back and forth until no further water vapor is expelled. Finally, allow the dish and residue to cool.

How to Reduce the Danger of Smoking
The Department of Health, Education and Welfare (HEW) has outlined some steps to take some of the danger out of smoking for those people who are unable to quit smoking outright. _________ choose a cigarette with less tar and nicotine to reduce your intake of these pollutants. _________ don’t smoke your cigarette all the way down. Smoke halfway, and you will inhale only about 40 percent of the total tar and nicotine. Remember, 60 percent of these substances is contained in the last half of the cigarette. ________ take fewer draws on each cigarette---that is, reduce the number of puffs on each cigarette. This will cut down on your smoking. _______ reduce your inhaling. Don’t open your lungs by inhaling deeply. Take short, shallow puffs _______ smoke fewer cigarettes each day. This may be the most difficult step of all. However, just follow these directions.
1. Pick a time of day to start, and don’t smoke before that time. 2. Don’t think of it as cutting down; think of it as postponing.
3. Carry your cigarette in a different pocket, or put them in a different place so that you can’t reach for them automatically.
_______ think about the terrible diseases you are opening yourself up to each time you smoke a cigarette. ________ if you follow each of these steps without cheating, you should be able to at least control the number of cigarettes you smoke daily. who knows, this might be the beginning of the end—of your smoking, that is.
