Observatory telescopes today are virtual behemoths compared to Galileo´s 1 3/4-inch-diameter (4.4 cm) models. His primitive devices were refracting telescopes. A large convex lens on one end formed the image and a small concave lens at the other end, later modified to be also convex, magnified the image. Remarkably, his instrument could magnify objects up to 33 times, allowing him to view such distant wonders as Jupiter´s four moons and Venus´ moon-shaped phases.

Modern reflecting telescopes use immense, bowl-shaped mirrors (up to 236 inches [600 cm] across!) to collect light from faraway heavenly bodies. They are thus able to detect objects ten million times fainter than those that can be seen with the naked eye. Why, it is claimed that one telescope in Australia could detect a candle flame a thousand miles (1,600 km) away! Interestingly, though, astronomers today still run into the same problem Galileo faced. The stars increased in number but not in size he noticed. Galileo reckoned that the stars must be incredibly distant to remain mere points of light under magnification.

The Role of Telescopes

In 1931 the electron microscope was invented. By aiming a stream of electrons at an object, a visual image can be produced in which objects are magnified about a million times. There is one serious drawback: It cannot be used to study living specimens. A new device, combining the optical microscope with computer memory and television cameras, now has scientists actually be able to study the biological activity of living cells! Microscopes and telescopes are thus powerful tools. Mankind has been given an incredible insight into the world and universe in which he lives.

In this day and age, air bed mattresses are not pigeon-holed as being only temporary solutions for sleeping arrangements. More and more, an inflatable air mattress is replacing the traditional metal spring mattresses that often cause sleeping problems and can be the cause of painful back conditions.

One of the advantages of air beds, is that they can be fine-tuned to your personal comfort level. In some instances, a person may need to change the firmness of their adjustable air bed from one night to the next, depending on the activities they were engaged in during the day or if they stressed or twisted their back. It is simply impossible with traditional mattress beds to have this kind of flexibility, in order to get the best sleep possible.

Air bed mattresses are able to conform around your body and your unique shape. In essence, this means that the air mattress bed cradles your frame, while at the same time provides the type of support you need and just where it is needed. Therefore, the pressure points that make so many people uncomfortable on standard mattresses are virtually done away with.

These pressure points can interfere with the natural alignment of your spine at night. Mattress beds that are too firm will not allow for the natural and essential curvature of the spine. At the same time, a mattress that is to soft does not provide proper support either. This can cause abnormal positioning of the spine which create bends, nooks and crooks that ultimately lead to pain. Therefore, if you find yourself waking up on a regular basis with persistent back pain, you would do well to consider switching to an adjustable air bed.

If your current mattress does not give your back the right support, you are setting yourself up for the development of chronic lower back pain. Back pain is a leading cause of reduced productivity in the workplace, missed days of work and the chronic use of pain relieving medications. Rather than deal with these types of consequences, a simpler solution would be to address the root cause of the problem and ultimately improve your sleeping conditions with an air bed.

You should also keep in mind that over the course of your life, your body goes through many changes. The natural aging process and various stresses and injuries that are inflicted upon it, will very likely require a different level of firmness in a mattress. With traditional coil spring mattress beds, this would mean that you would need to purchase a new mattress, but with an air bed, it is simply a matter of making a firmness adjustment to your air bed mattress to match your changing needs.

On the market today, you can find a large number of choices in air bed mattresses and you will almost certainly find the right inflatable air bed to meet your needs and your budget. Depending on the quality of the material and various options you can choose from, you can expect to pay anywhere from a couple of hundred dollars up to a few thousand dollars. No matter the kind you choose, you will enjoy a more restful sleep and have better support than you had with your traditional mattress.

Every cigar enthusiast probably has his favorite cigar lighter or ashtray but there are also other special cigar accessories available. In this article, we’ll uncover a few simple items that will make cigar smoking a more pleasurable experience.

Cigar cutters are used to remove or penetrate the cap of a cigar before smoking it. There are three basic types of cuts: the straight cut, the wedge or “V” cut and the hole punch. The type of cut to make is based on personal preference and the size and/or shape of the cigar. The straight cut is the most common. The double blade guillotine is preferred by many aficionados because it usually makes a cleaner cut. The wedge or “V” cutter resembles the guillotine cutter, but the shape of the blade slices a wedge into the cap of the cigar instead of cutting it completely off. The hole punch is used to put a hole in the cap of the cigar instead of just cutting it off. If a cutter or hole punch isn’t available, a hole cut can be made in a cigar using a pen or pencil.

If you are one to purchase expensive varieties, like a Cuban cigar, then here is a cigar accessory you’ll definitely need. Unlike a cigar box, a humidor prevents your cigars from drying out or becoming infested by insects. For private use, small wooden or acrylic glass humidor boxes will store a few dozen.

Chlorophyll and parsley extract will make your mouth fresher while vitamin A, vitamin C, garlic extract, spirulina, young barley or wheat grass will all help to cleanse your body of nicotine.

To avoid offending people who don’t share your appreciation for the aroma of cigar smoke, keep a few key products around your home to get rid of the smell and pay attention to your personal hygiene. This will make cigar smoking pleasurable for everyone.

When looking for good cigars, also think of a cigar humidor to keep them fresh.

Fortunately, cigars have now entered the mainstream and although they were once the symbol of the rich and powerful, it’s easier than ever for just about anyone to purchase a good cigar. You will surely be able to buy your friend a top quality cigar that will put a smile on their face, even if you can’t afford top-tier Cubans.

First, visit your local tobacconist or specialty smoke shop for the best quality and widest selection but avoid ‘drugstore’ cigars. Drugstore cigars indeed may be inexpensive and convenient, however they usually contain preservatives and are of very poor quality. Make sure that the cigars you purchase are made of 100 percent tobacco, as some may contain saltpeter, glycerin, and other preservatives and irritants. If you have any questions regarding the cigar’s ingredients, always ask the salesperson. An experienced and knowledgeable sales clerk will be able to provide you with extensive information about the ingredients.

The best place to shop for cigars is usually your local tobacco shop, because you will be allowed to smell and touch the cigars. A good quality cigar will give a little when squeezed, with no excessively hard or soft spots, so be sure to squeeze the cigar and never buy a lumpy one. If you notice any drying or discoloration in the wrapper, it is best not to buy it. The best cigars are ideally smooth and tight. Inspect the end of the cigar, and look at the color of the tobacco to make sure it is evenly colored. If the color changes abruptly, then the cigar was probably not rolled properly, although some color variation is normal. Uneven burning and unpleasant odors are often the result of an improperly rolled cigar.

If you know your friend is an experienced and regular smoker, choose a cigar that is greater in diameter because these cigars tend to have a richer flavor that experienced smokers will appreciate. Finally, ask your friend if he knows about cigar humidors. They are an excellent device for storing cigars.
