IQ Boost Anyone?









How To Boost Your IQ by: Dr. Enigma Valdez, C.H.
You may think that you’re stuck with the current IQ that you have for good. However, there is a way that you can boost your IQ to a much higher level than you thought possible. A French psychologist by the name of Alfred Binet first published the modern intelligence tests to evaluate if special students need help in school classes in 1905. Then a few years later in 1912, a German psychologist by the name of William Stern came up with the term “intelligence quotient” or I.Q. After him, there was a formula developed to identify the intelligence level of a person that is used up to this day. The formula is as follows; 100 multiplied Mental Age divided by Chronological age. For example, if a 10 year old child scored as high as the average 13 year old, then the child would have an IQ of 130. (100 times 13 divided by 10) The best way to boost your IQ and to land high IQ test scores is to buy study versions of the standardized tests. There are many kinds of IQ tests and they do come in many forms. Some of them use several sub portions, and are divided into different sections, such as verbal, math, spatial, etc. Others use a single item or type of question. The typical IQ test will require you to solve a number of problems in a supervised setting. You may also be timed. The IQ test will include things from various domains, such as spatial visualization, perceptual speed, short-term memory, and verbal skills. There are other IQ tests, that are not supervised and do not have a time limit. These are usually geared for measuring very high intelligence. When you are preparing to study for your IQ tests, determine which kind you are going to take. The most widely used IQ test is the Wechsler Adult Intelligence Scale or WAIS. There are about 14 subtests within this IQ test, which include object assembly, symbol search, picture arrangement, matrix reasoning, block design, digital symbol coding, picture completion, letter & number sequencing, vocabulary, and numerical reasoning. So, you can search for study guides for the main IQ tests, such as the WAIS, Stanford-Binet, Miller-Analogies, Cattell Culture Fair II, and Raven’s Progressive Matrices. You can go to Amazon.com or to Barnes & Noble to find study guides. You can also buy brain teaser books and go over the exercises. Don’t just do them once or twice, but practice them over and over, until they are imprinted on your brain. What starts to happen is that you will subconsciously pick up a pattern of these IQ tests, and you’ll be able to easily solve almost any question or problem. The thing about standardized IQ tests is that that they all pretty much have the same questions over and and over again, except they are worded or arranged a little different. The main patterns and principles remain constant. You can also test for the Graduate Record Exam or GRE. This test is accepted by major High IQ societies such as MENSA. I have found that the Graduate Record Exam has a lot of the same questions and structures in it that the standardized IQ tests have. Getting a study copy of the GRE is pretty easy, and you could probably get an older copy at your local public library. Just do the exercises over and over again, so you can get used to the structures of the questions. Then, after you have taken your IQ test and scored high, you can take the results and join different high IQ societies. This can help you in your personal life as well as your career. A lot of people will list the fact that they are members of certain high IQ societies on job resumes, and it can mean the difference between getting hired or rejected. Boosting your IQ is nothing short than practicing IQ tests. The more you practice taking them, the easier they get, and pretty soon, you, too can have a genius IQ.

Don't Waste Seeds..

Simple Seed Saving by: Dr. Christopher Kline
Seed saving can be a rewarding and cost saving activity particularly if plants are selected for their good seed saving characteristics. This article will offer the beginning seed saver helpful advice on which plants to start with and how best to harvest, prepare and save the seeds. Bean/pea, lettuce, pepper, and tomato offer the beginning seed saver the best chance for successful seed saving. They produce seed the same season as planted and are mostly self-pollinating, minimizing the need to be mindful of preventing cross-pollination. Always harvest seeds from the best plants available. Choose healthy disease-free plants with desirable qualities. Look for the most flavorful vegetables or beautiful flowers. Because seed set reduces the vigor of the plant and discourages further fruit production, wait until near the end of the season to save fruit for seed. Seeds are mature when flowers are faded and dry or have puffy tops. Beans/Peas Toward the end of the season and while healthy pods are still being formed allow the pods on some plants to dry brown before harvesting. This is about six weeks after eating stage for beans and four for peas. If frost threatens, pull the entire plant, and hang in cool, dry location until pods are brown. Lettuce With lettuce you will need to take care to separate varieties flowering at the same time by at least 20 feet to avoid cross pollination. Some outside leaves can still be harvested for eating without harming seed production. Once half the flowers have gone to seed, cut off the entire top of the plant and allow it to dry upside down in an open paper bag for 2-3 weeks. Peppers Some care must be taken to separate different varieties by at least 50 feet help ensure purity. Most peppers turn red when fully mature and this is the time to harvest seeds for saving. If frost threatens before peppers mature, pull the entire plant and hang in cool, dry location until peppers mature. Cut open mature peppers and scoop out the seeds. Follow with a gentle washing in a mild 10% bleach solution, and lay the seeds out in a single layer on white paper towels until the seeds have thoroughly dried. Tomatoes If possible, allow tomatoes to completely ripen before harvesting for seed production. Slice open the tomato, squeeze out the pulp and seeds into a glass jar, add water up to about ¾ of the jar, and set aside for a few days. A residue will collect on the top of the water as well as some of the seeds (these are dead seeds). The water will clear and the viable seeds will sink to the bottom of the jar. After five days carefully scoop out the residue from the top and throw it away, pour off the water and then pour out the seeds from the bottom of the jar onto white paper towel for drying. Seed Storage Paper envelopes work well for storing each seed variety. Before storing test to make sure the seeds are dry enough by attempting to bend them. If the seeds snap instead of bending they are sufficiently dehydrated for storing. Large mason jars work well for storing your seed envelopes. Prepare a jar for seed storing by placing a small, cloth bag filled with dry, powdered milk in the bottom of the jar. This will help to absorb any moisture from the storage container. Place the seed envelopes in the jar, on top of the bag and tightly seal the jar. Next place the jar in the freezer for two days. This helps to kill any diseases that may be infecting the seeds. Find a place for long term storage that is a cool, dry, and dark where the temperatures remains fairly stable. A garage, storeroom, pantry, closet or even a drawer will work well. A few weeks before planting time perform a test germination of saved seeds by placing the seeds on three layers of moist white paper towels, roll the towels loosely and place them in a plastic bag. Keep the bag in a warm place until germination occurs. Depending on the type of seeds germination may take anywhere from 2-14 days.

How to Grow Crystals

Growing Crystals by: Kevin Clement
Tip, Tricks, and Techniques Do you want to grow great crystals? These are general instructions for growing crystals that you can use for most crystal recipes. You can find the recipes and information on crystal structures in the Growing Crystals section. Here are the basics, to get you started and help you troubleshoot problems: What Are Crystals? Crystals are structures that are formed from a regular repeated pattern of connected atoms or molecules. Crystals grow by a process termed nucleation. During nucleation, the atoms or molecules that will crystallize (solute) are dissolved into their individual units in a solvent. The solute particles contact each other and connect with each other. This subunit is larger than an individual particle, so more particles will contact and connect with it. Eventually, this crystal nucleus becomes large enough that it falls out of solution (crystallizes). Other solute molecules will continue to attach to the surface of the crystal, causing it to grow until a balance or equilibrium is reached between the solute molecules in the crystal and those that remain in the solution. The Basic Technique 1. Make a saturated solution. 2. Start a garden or grow a seed crystal. 3. Continue growth. In order to grow a crystal, you need to make a solution which maximizes the chances for the solute particles to come together and form a nucleus, which will grow into your crystal. This means you will want a concentrated solution with as much solute as you can dissolve (saturated solution). Sometimes nucleation can occur simply through the interactions between the solute particles in the solution (called unassisted nucleation), but sometimes it's better to provided a sort of meeting place for solute particles to aggregate (assisted nucleation). A rough surface tends to be more attractive for nucleation than a smooth surface. As an example, a crystal is more likely to start forming on a rough piece of string than on the smooth side of a glass. Make a Saturated Solution It's best to start your crystals with a saturated solution. A more dilute solution will become saturated as the air evaporates some liquid, but evaporation takes time (days, weeks). You will get your crystals more quickly if the solution is saturated to begin with. Also, there may come a time when you need to add more liquid to your crystal solution. If your solution is anything but saturated, then it will undo your work and actually dissolve your crystals! Make a saturated solution by adding your crystal solute (e.g., alum, sugar, salt) to the solvent (usually water, although some recipes may call for other solvents). Stirring the mix will help to dissolve the solute. Sometimes you may want to apply heat to help the solute dissolve. You can use boiling water or sometimes even heat the solution on the stove, over a burner, or in a microwave. Growing a Crystal Garden or 'Geode' If you just want to grow a mass of crystals or a crystal garden, you can pour your saturated solution over a substrate (rocks, brick, sponge), cover the setup with a paper towel or coffee filter to keep out dust, and allow the liquid to slowly evaporate. Growing a Seed Crystal On the other hand, if you are trying to grow a larger single crystal, you will need to obtain a seed crystal. One method of getting a seed crystal is to pour a small amount of your saturated solution onto a plate, let the drop evaporate, and scrape the crystals formed on the bottom to use as seeds. Another method is to pour saturated solution into a very smooth container (like a glass jar) and dangle a rough object (like a piece of string) into the liquid. Small crystals will start to grow on the string, which can be used as seed crystals. Crystal Growth and Housekeeping If your seed crystal is on a string, pour the liquid into a clean container (otherwise crystals will eventually grow on the glass and compete with your crystal), suspend the string in the liquid, cover the container with a paper towel or coffee filter (don't seal it with a lid!), and continue to grow your crystal. Pour the liquid into a clean container whenever you see crystals growing on the container. If you selected a seed from a plate, tie it onto a nylon fishing line (too smooth to be attractive to crystals, so your seed can grow without competition), suspend the crystal in a clean container with saturated solution, and grow your crystal the same way as with seeds that were originally on a string. Keeping Your Treasures Crystals that were made from a water (aqueous) solution will dissolve somewhat in humid air. Keep your crystal beautiful by storing it in a dry, closed container. You may wish to wrap it in paper to keep it dry and prevent dust from accumulating on it. Certain crystals can be protected by being sealed with an acrylic coating (like Future floor polish), although applying the acrylic will dissolve the outermost layer of the crystal.

Scientists Find Oldest Human

Scientists Discover Oldest Skeleton Of Human Ancestor; Report Face Looked Like Hugo Chavez. by: Tom Attea
The most well-preserved skeleton of an ancestor of homo sapiens has been discovered in Ethiopia. The skeleton, dating back about 3.3 million years, is a member of the evolutionary group known as Australopithecus Venezuelas and had a face that looks remarkably like Hugo Chavez. Scientists have yet to determine if the homonid retained tree-climbing capabilities. Apparently, its arms hung below its knees, and it had a short neck like a gorilla. As they free more of the skeleton from the sandstone in which it was found, they will be able to determine if it did climb trees. Remains of an ancient manuscript were also found buried with the skeleton. It appears to be the work of an ancient medicine man who identifies himself as Neander Chompsky. Experts are attempting to decipher the language in which it is written. The scientists also discovered scratchings on a rock. So far they have been able to determine that the precursor of homo sapiens may have believed in the devil. One of the scratchings has been translated that states, "If you're looking for the devil, first look into a reflecting pool." Meanwhile, Hugo Chavez, on hearing about the remains, asked that they be turned over to Venezuela, because, if the ancient person did look just like him, he or she may be a distant ancestor, and so, he reasons, the remains belong to the Chavez family. He has also voiced the intention to lug the rock with the etchings on it to his next speech at the UN, where he plans to say he took its advice and looked into a reflecting pool to see the devil. He saw George Bush, because right before he looked, he tossed in a photograph of him.

More On Global Warming

Space Sunshade May One Day Reduce Global Warming by: Deepak Purang
Global warming is a reality and increasingly its consequences are upon us. We may think that global warming does not affect us but the fact is it has already started to have disastrous consequences. Flash floods, droughts, receding icebergs, cyclones are some of the manifestations of global warming. Although we are aware and worried about it and trying our best to control it but no significant impact could be seen. Scientists have come up with new strategies to tackle the problem. Now a scientist has suggested an ambitious idea to contain global warming. Put sunshades in space. That’s right. University of Arizona astronomer Roger Angel suggests putting sunshades in space and has detailed his idea in a paper “Feasibility of cooling the Earth with a cloud of small spacecraft near L1” in the Proceedings of the National Academy of Sciences. He suggests launching a constellation of trillions of small free-flying spacecraft a million miles above Earth into an orbit aligned with the sun, called the L-1 orbit. This spacecraft would form a long, cylindrical cloud and would have a diameter about half that of Earth, and about 10 times longer. It is suggested that about 10 percent of the sunlight passing through the 60,000-mile length of the cloud, pointing lengthwise between the Earth and the sun, would be diverted away from our planet. This would result in uniformly reduced sunlight by about 2 percent over the entire planet and would balance the heating of carbon dioxide in Earth's atmosphere. The use of space shade was first mooted by James Early of the Lawrence Livermore National Laboratory in 1989. "The earlier ideas were for bigger, heavier structures that would have needed manufacture and launch from the moon, which is pretty futuristic," Angel said. "I wanted to make the sunshade from small 'flyers,' small, light and extremely thin spacecraft that could be completely assembled and launched from Earth, in stacks of a million at a time. When they reached L1, they would be dealt off the stack into a cloud. There's nothing to assemble in space." Angel proposes to design lightweight flyers made of transparent film pierced with small holes and would be two feet in diameter, 1/5000 of an inch thick and weigh about a gram, the same as a large butterfly. He suggests using “MEMS” technology mirrors as tiny sails that tilt to hold the flyers position in the orbiting constellation. The weight of all flyers would be 20 millions tons. But conventional rocket launch system at $10,000 a pound would be too prohibitive. His alternative would cost only around $20 a pound. He suggests deploying a total 20 electromagnetic launchers launching a stack of flyers every 5 minutes for 10 years. The electromagnetic launchers would use hydroelectric power but even if it uses coal-generated electricity, each ton of carbon used would reduce the effect of 1000 tons of atmospheric carbon. Once propelled beyond Earth’s atmosphere the flyer stacks would be steered to L-1 orbit by solar-powered ion propulsion, pioneered by European Space Agency's SMART-1 moon orbiter and NASA's Deep Space 1 probe. "The concept builds on existing technologies," Angel said. "It seems feasible that it could be developed and deployed in about 25 years at a cost of a few trillion dollars. With care, the solar shade should last about 50 years. So the average cost is about $100 billion a year, or about two-tenths of one percent of the global domestic product." He added, "The sunshade is no substitute for developing renewable energy, the only permanent solution. A similar massive level of technological innovation and financial investment could ensure that. "But if the planet gets into an abrupt climate crisis that can only be fixed by cooling, it would be good to be ready with some shading solutions that have been worked out."

Global Warming Discussion

A New Science For A New Climate by: Jacob Fiennes
At first glance it’s hard to imagine how the proliferation of human activity upon the environment has been a major factor in climate change given that climate change alone is nothing new. Over two million years the earth’s history has seen enormous changes. Indeed, in the last ten thousand years the warming and cooling of the earth has been on a larger scale that what we see today.
The climate is however very changeable these days. Getting the politics right has been half the fight. Unfortunately, the right policy has been held at bay partially by having the right knowledge of what’s happening to the climate. The climate changes we see today are the result of only a century and a half of study, peanuts in comparison the huge shifts over the earths history.
The recent UN Climate Change Conference sought to put in place a policy to take over the Kyoto protocol. At its core were some recently publicised results:
The warming trend on the earth’s surface has been taking place since the early part of the twentieth century. The last ten years have been the warmest of that millennium.
There have been rapid signs of melting the Arctic circle. The sea ice there has fallen by around eight percent over thirty years.
The old inconsistency in the data between the temperature rise in the atmosphere and on the planets surface seems to have levelled out. They appear to rise in parallel.
The Scripps Institute of Oceanography in California noted that the ocean has been warming at different depths for over 65 years. These results match the predictions that warming has been induced more by greenhouse gases that as a result of small changes in the suns heat output.
There has been an observed and recorded link between the sea surface temperature and the frequency and intensity of tropical storms, typhoons and hurricanes.
The existing computer models of the change in ocean currents, in particular in the North Atlantic, are correct.
There are however still some unknowns. For example the solar hypothesis is now known to be a lesser contributor, the miniscule changes in the suns heat output over its eleven year sunspot cycle is adding to the mix. Also, the aerosol emissions from sulphurous fuel promote the formation of clouds, and as a consequence the sunlight reflected from the earths surface increases, effectively opposing the greenhouse gas effect.
Some even argue for the benefits of global warming, which include for example the opening up of new shipping lanes in the artic as the ice recedes, new oil drilling opportunities and longer harvest periods in Canada and Russia.
It seems climate change is inevitable and the small economic ideas such as banning coal subsidies bear little fruit as a means of curbing the problem. More than ever, political will must be demonstrated at first to show to industry and populations that it is even an issue. More importantly perhaps, the will of the politicians must be met with achievable methods from the technological and scientific community.
Professor Socolow is leading the way with what he calls “stabilisation wedges”. On a graph of climate change, the space between the trend line and the stability line is known as the “stabilisation triangle’. By dividing these triangles into wedges and assigning realistic goals to each wedge the massive problem is given a usable and effective solution.
The goals to assign to the wedges range from greater overall efficiencies, the decarbonisation of electricity, fuel displacement by low carbon electricity, methane management, and natural carbon sinks. By further subdividing each wedge into sub wedges, such as decarbonised electricity being subdivided into nuclear power, renewable energy, natural gas as an alternative to coal, and the storage of carbon dioxide – these problems are confounded into what everyone has been looking for. A short list of solutions that together will balance the problem.
It seems the technology for all this exists. It is merely in need of refinement. For example the management of carbon dioxide from the burning of fossil fuels could be dealt with through further carbon sequestration. A couple of power plants already employ this particular technique to good effect. The carbon dioxide is extracted at the source and is injected into porous rocks deep underground to prevent it escaping into the atmosphere.
Steam reformation is another technique. It is, in essence, a pre-emptive technique that reacts the fuel used with water to yield hydrogen. The hydrogen output is burnt to create electricity.
Of all the possibilities of reworking and inventing technologies, perhaps the best idea is the oldest idea. Replanting programmes. The idea of photosynthesis to combine carbon dioxide with water and sunlight is a relatively cheap and exponential idea and would be hugely effective.
