Using alternative fuel sources is not just a matter of environmental responsibility. It is not just about assuaging your conscience. It is good sense, and sound planning. Although most of us are in denial, the fossil fuels which form the backbone of our world economy are dwindling quite rapidly, even as we go about our daily business in our cars. Although few Americans use an alternative fuel source to commute, those who do are soon going to be at an advantage. If your alternative fuel source is your feet, whether through walking or bike riding, you are already at an advantage, taking care of your body and using transportation that is essentially free. However, even if you can not get around solely on your feet, it makes sense to start planning your life around alternate fuel sources now, before things go any farther. Although few Americans use an alternative fuel source to commute, those who do are soon going to be at an advantage. If your alternative fuel source is your feet, whether through walking or bike riding, you are already at an advantage, paying nothing to move from one place to another and training your body at the same time. However, even if you can not get around solely on your feet, it makes sense to start planning your life around alternate fuel sources now, before it becomes too late. In addition, many areas will probably not be adequately prepared to work with an alternative fuel source. There may be no where to even refill your biodiesel cars, and that will make things quite hard. People will have become so used to the convenience of their gas powered vehicles, that they will not be able to really get around this formidable-looking problem. But if you plan your life around an alternative fuel source, you will have no trouble adjusting. The most fool-proof alternative fuel source is your own two feet, but since not all of us have athletic bodies or enjoy walking hours under the sun and snow, the real solution is public transport. If you live in an area where public transportation is already in place, and runs on electric vehicles, then congratulations. I bet that your local economy will suffer far less damage from the fuel crisis. The public transit, driven by an alternative fuel source, will be able to pick up the extra passengers who have been forced to suddenly give up their cars, and there will be minimal inconvenience. If you have an electric vehicle, you will similarly be in a good position, as electricity will always be a good alternative fuel source. No matter how bad the fuel crises gets, the government will know better than letting the national power grid collapse. Therefore, electricity makes a lot of sense.

We build our reality on our beliefs. And although we don’t admit that they are only our beliefs we do set our lives by them. They become us – our reality - and woe to anyone who tries to ridicule or challenge our faith. Through the recent discovery of certain biblical-like documents, scholars are now toying with the understanding that Judas was the true buddy of Jesus rather than his traitor. According to these writings, Jesus so trusted Judas that he selected him out of all the other apostles to co-ordinate the role and act as a traitor - to fulfil the prophecy. Will Judas now be declared as a saint and a martyr? If these writings are accepted to be true what will happen to all Christian believers? Here is another example. Millions believe that the American astronauts ascended on the moon and returned back. At this point in time, I am not opening the argument of a moon hoax but, what will happen to these millions when in the not too distant future it will be revealed that it was all a hoax? Both religion and science could create fanatics from their followers. Belief is a very sensitive and dangerous thing. Confusion and chaos are still the price for many a different belief. Both God and gravity are still a phenomenon. They are both unproven entities and yet man hold on to what he thinks about them as fact. As regards to gravity, man today is still in the dark as he was when he believed that the earth was flat. Here, may I ask, what if all the planets (including our moon) have the same gravitational forces? It is quite a different story when a non-scientist dares to direct reasoned criticism at science - the majority of professional scientists immediately object. I consider myself as another Faraday. The sad thing is that we are easily entangled into illusions and let these same illusions direct our lives. We should always question certain issues that are coming from the so-called ‘reliable’ sources (media, government and institutions). There may be hidden agendas behind everything we hear or see - such as marketing issues for purposes beyond our knowing. To doubt and question is healthy. It can provide you with an opportunity to explore horizons that previously were inaccessible due to the narrow outlook of the issue.

One of the most important telescopes in the history of astronomy, the Hubble telescope has allowed observers to peer farther into space than any previous telescope. By moving outside and above the atmosphere of the earth, the Hubble telescope has been able to observe visual data much more clearly than a terrestrial telescope, and it has been able to see much farther into the ultraviolet and infrared spectrums as well, since these spectra are largely absorbed by the earth’s atmosphere. Thus, by moving the observing platform into open space, the Hubble telescope has given a much clearer view of the universe, allowing scientists to peer even deeper into space. The Hubble telescope is named for Edwin Hubble, the astronomer who originally determined that the universe is expanding. This discovery, one of the foundations of modern astronomy and cosmology, made Hubble an excellent choice for the honor of having this telescope named for him. The concept for the Hubble telescope was originally the idea of Lyman Spitzer back in 1946. He clearly saw that earth-based telescopes were inherently limited in their ability to see into the heavens, since dust, clouds, and even turbulence in the atmosphere interfered with telescopes’ clarity. Which meant that the best way to get a clear image from a telescope was with a telescope that was in orbit around the earth. After some success with the smaller Orbiting Astronomical Observatory, the plan for a large scale telescope was born. There were some fits and starts however, mostly due to budget constraints, and the project did not really take off until the 1970’s and funding was not approved until 1978. Then, with funding in place, plans were made to launch the Hubble telescope in 1983. However, due to various delays, it was not actually launched until 1990. After a few early problems, the Hubble telescope finally started sending back clear images. And those images were well worth the effort. The Hubble telescope was able to achieve a sharpness and resolution that was unimaginable with a standard, earth-bound telescope; crisp images that not only showed new detail in known areas of space, but also peered deeper into space than ever before. And with these new images, astronomers have been able to discover new and exciting information about our universe. However, it is not only astronomers who have been amazed at the images that the Hubble telescope has produced. In fact, the images from Hubble are delights to view all on their own. From the clearly defined galaxies, to pictures of nebulae, to the Apollo 15 landing site, Hubble has been as exciting for the public as it has been for scientists. As the Hubble telescope ages, its future is uncertain. Corrective software has allowed earth-based telescopes to pick up much of the information previously possible only with a space-based telescope. And as NASA retools itself to follow its mandate to take a man to Mars, money that would be spent on maintenance of the Hubble is being spent elsewhere. However, before the Hubble telescope enters the atmosphere sometime in 2010, it will provide a remarkable window into the universe and all that is in it.

Getting the flu is bad enough, but getting the flu while you’re pregnant can be a nightmare. There is a greater chance that you will stay sick longer, there are only have a few medications that you can take to safely relieve flu symptoms, and your risk for developing flu-related complications is increased. That’s why the best thing for pregnant women to do during flu season is to take all possible precautions to avoid the virus, including getting a flu shot. Influenza, or the flu, is a very contagious virus that affects the upper respiratory system causing fever, muscle aches, cough, sore throat, runny nose and weakness. The flu usually makes its appearance in winter and early spring, but it can also strike in the fall and late spring as well. While the virus is a nasty thing for anyone to catch, with pregnancy and the flu it can be particularly risky because a woman’s immune system has weakened slightly during the pregnancy. Because of this, pregnant women are more likely to experience symptoms for a longer period of time, and their risk of developing complications, such as pneumonia, is increased. Studies have shown, however, that pregnancy and the flu poses little risk to an unborn child. The best way for pregnant women to avoid the flu is to get a flu shot. Flu shots are recommended for nearly all pregnant women and are usually given in October or November right before flu season starts. Getting vaccinated is the best way to protect yourself from the virus and can save you a lot of discomfort during the flu season. Other ways to avoid combining pregnancy and the flu include: Frequent hand washing: This is one of the most important things you can do for yourself to avoid illness. Wash your hands thoroughly before and after meals, after using the bathroom and frequently throughout the day. Washing your hands with antibacterial soap to get rid of germs is one of the easiest ways to stay healthy. Stay away from people who have colds or the flu: Common sense should tell you to avoid people who are already sick. Coming into contact with contagious individuals is an easy way to get sick yourself, so if possible, just avoid sick people altogether until they are no longer contagious. Keeping your hands away from your nose, mouth and eyes: Germs like to come in through these particular places, so try not to touch them. If you are unfortunate enough to get the flu, there are a few things that you can do to ease the symptoms and recover faster. Remember though, with pregnancy and the flu, there are many medications that you cannot take because they could be harmful to you or your baby. Be sure to talk to your doctor before taking any medicine to treat your flu symptoms. The following treatments can help if you come down with the flu: -Acetaminophen for fever, aches, and pains -Chlorpheniramine, an antihistamine -Honey or other natural ingredient lozenges for a sore throat -Lots of rest -Increased fluid intake, especially water, juice, and tea Getting the flu is no fun. Getting the flu while you’re pregnant is REALLY no fun. Pregnancy and the flu just don’t mix, so do your self a favor by getting a flu shot and taking preventative measures to avoid the virus.
