Math and Science Educational Resource Availability, Part 2
Wednesday 25 February 2009 @ 10:42 am

Clear Terms
We need to be clear on some terms. What constitutes a “math and science resource?” This might be seen as a gross generalization, but here’s our working definition:

Anything that acts to stimulate the imagination as related to technology and causes the student to consider the underlying scientific and mathematical concepts of the presentation material is a good math and science resource. In the best of all worlds, this consideration is then personalized and the student takes the initiative in pursuing further information.

The general response to this definition is something like: “Well, that works fine for the basic science. But what about the mathematics involved?” That leads to our second assumption and definition:

Math is the language of science. If you’ve kindled the interest in one, you’ve laid groundwork for the other. At some point in the further pursuit of information, the student will be sufficiently exposed to both elements because one tends to require the other.

So the trick to kindling this level of “personalized interest” will lie in the means of presentation.

Learning Styles
The resource materials need to be “appropriate” on two levels: age appropriate and learning style appropriate. I personally favor letting the age appropriateness of the material find its own level. In any group of students, there will be fast learners and slow learners; more abstract thinkers and less abstract thinkers. Experience tells me that this distinction is *usually* based on age. But perhaps a better term would be “mental or intellectual maturity.” If it’s too far over their heads or beneath their abilities, they’ll filter it out. That’s beyond the control of the presenters and will sort itself out.

Learning style, on the other hand, can be catered to. There are generally considered to be three “styles” of learning: Visual, Auditory, and Tactile/Kinesthetic. All this implies is that there are three preferred (not necessarily mutually exclusive) ways by which students tend to assimilate knowledge:

  • By seeing the information
  • By hearing the information
  • By touching or moving with the information

If students can hold something in their hands to look at and perform an activity with it during or following a verbal presentation, their chances of retaining information about that subject are increased. But that’s not to say no learning takes place if the information is only seen, or only heard or only touched. It merely predicts the learning process will be more successful when all three elements are combined.

The Aerospace Educational Development Program (AEDP) has attempted to combine elements of each of these learning styles into its on-line material. The General Astronomy Education Page provides hot-linked material that is visual and sometimes auditory. The Animated Astronomy Education Page provides hot-linked material that is moving and often of a multi-media basis. The Scale Model Communication Satellite provides something that the student can actively assemble, hold in their hands and actually see the various components of the space craft. Additional materials are currently being developed and added to the site.

Encompix ERP Software Profiled in Quality Digest
Tuesday 24 February 2009 @ 9:40 pm

The September issue of Quality Insider produced by Quality Digest online profiles Engineer-to-Order Manufacturing and a rundown of its different set of quality standards and tools. According to Cutler, the author of the feature article, “In repetitive manufacturing you can apply Statistical Process Control (SPC) techniques to purchased components and manufacturing quality as well as scrap and yield. Statistical analysis is acceptable if a company is mass purchasing or mass manufacturing the same product to the same standards every time. The essence of ETO is building a unique complex product every time. There may be components that are common from one machine to another, but not in the same quantity as a repetitive manufacturer.” Cutler profiles several Encompix ERP clients in the feature article. Encompix (www.encompix.com) has filled the manufacturing software requirements of Engineer-to-Order companies since 1992. The company name reflects the commitment to developing business application solutions that encompass the complex areas of project-based and job-based manufacturing. Encompix provides ETO manufacturers with a competitive advantage by improving bottom line results. The feature article can be found at www.trcutlerinc.com. In the increasingly competitive world of engineer-to-order and project-based manufacturing, companies have to operate at maximum efficiency to compete with not only domestic, but also the growing number of overseas competitors. The companies that will thrive in this environment are those that are continually looking for improvement. Thomas R. Cutler, President & CEO of Fort Lauderdale, Florida-based TR Cutler, Inc. (www.trcutlerinc.com), is the nation’s leading manufacturing journalist. Cutler is the founder of the Manufacturing Media Consortium of 2000 journalists writing about trends in manufacturing. Cutler is the lead spokesperson for the ETO Institute (www.etoinstitute.org). Cutler is also the author of the Manufacturer’s Public Relations and Media Guide.

Different Branches Of Chemistry
Monday 23 February 2009 @ 7:03 am

Chemistry is generally divided into two broad branches: organic chemistry and inorganic chemistry. Other types of chemistry include physical chemistry, biochemistry, and analytical chemistry, with each field branching off into several specific subfields. Here’s a brief description of the most common branches of chemistry.

Organic Chemistry

Organic Chemistry has to do with the study of compounds that contain carbon (and sometimes hydrogen). Even though carbon is only the fourteenth most common element on the planet, it produces the greatest number of different compounds on Earth. Not surprisingly then, much of the study of chemistry involves organic chemistry.

The most studied groups of organic compounds are those that contain nitrogen. These organic compounds are important because they are often linked to the amino group. When the amino group combines with the carboxyl group, amino acids are born. Amino acids are important because they are as the building blocks of proteins.

Inorganic Chemistry

Inorganic chemistry involves the study the properties and reactions of compounds that do not contain carbon and which are not organic. Inorganic chemistry studies all non-living matter, such as minerals found in the Earth’s crust. There are many branches of inorganic chemistry, including geochemistry, nuclear science, coordination chemistry, and bioinorganic chemistry.

There is much overlap between organic and inorganic chemistry. For instance, organometallic chemistry studies the use of compounds that are capable of creating a covalent bond between carbon and metal.

Physical Chemistry

As its name implies, physical chemistry has to do with the physical properties of materials. Physical properties that are studied may include the electrical and magnetic behavior of materials, as well as their interaction with electromagnetic fields.

There are several subcategories of physical chemistry. These include thermochemistry, electrochemistry, and chemical kinetics. Thermochemistry studies the changes of entropy and energy that naturally occur during chemical reactions. Electrochemistry is concerned with the study of interconversions of electric and chemical energy of matter, as well as the effects of electricity on chemical changes. Chemical kinetics involves the study of chemical reactions. Specifically, chemical kinetics studies the equilibrium it reached between products and their reactants.

Biochemistry

Biochemistry is a branch of chemistry concerned with the composition and changes of living matter. Biochemists commonly focus on the physical properties and structures of biological molecules. Common biological molecules include carbohydrates, proteins, lipids, and nucleic acids. Biochemistry is sometimes referred to as physiological chemistry and biological chemistry. Biophysics, molecular biology, and cell biology are research fields closely related to biochemistry.

Analytical Chemistry

Unlike the other main types of chemistry, analytical chemistry doesn’t deal specifically with specific elements. Analytical chemistry is concerned mainly with the various techniques and laboratory methods used to determine the composition of materials. Qualitative and quantitative analysis are the two most basic methods used in analytical chemistry. Qualitative analysis has to do with identifying all the atoms and molecules in a sample of matter, with attention paid to trace elements. Quantitative analysis also involves determining the atomical and molecular structure of matter, but includes also measuring the exact weight of each chemical constituent.

Dreams and Creating
Thursday 19 February 2009 @ 2:19 pm

How can we remember and learn from our dreams?

The same way we remember and learn in the waking state. We must be conscioussly aware in both states. Even in our waking state we are not fully conscious most of the time, and we don’t always remember everything. Our brains scan all the information we receive during the day and filters out what is important for us to remember and the rest seems forgotten, lost in our subconscious. It is the same with dreams. We remember only the informaition that we have programmed ourselves to remember. We do this programming through our beliefs in the validity of dreams. What we expect from our dreams helps determine what we remember.

Our conscious recollection of our dreams is often proportional to our conscious recollection in the waking state. Being more consciously aware in our waking state helps us to be more consciously aware in our dream state, and being more consciously aware in our dream state, helps us to be more consciously aware in our awake state.

Joy is found through out the universe. To follow your joy is to become the universe.The key to any universe is through joy. All the universes big and small can be entered through their own vibrational patterns of joy. Universes await your visits, which are made possible by aligning with that vibrational pattern of joy. All it takes is an adjustment in our vibratory frequency and we can visit the universe held in the head of a pin, or the universe that holds the universe that holds the universe that you are in. There are countless universes going on right now in the very space that you are in. Like a radio, we only need to adjust the frequency to tune in to any of these universes. To turn the dial, we must first be aware of the frequency in which we operate. We cannot let go of that frequency if we are not even aware of it. We are afraid, though, to let go of our frequency, for we are afraid we will not be able to get back. But to get back, we merely have to turn the dial back, and that is easy because our intense focus on our present dimension creates a default setting for our consciousness to come back to. We visit other dimensions in our sleep every day, yet we are not generally afraid of not coming back.

Password Generators
Tuesday 10 February 2009 @ 3:39 pm

Always look for a password that is difficult to crack and is unlikely to be easily compromised. Usually, the best method for generating a password is to select a sufficient number of characters chosen at random. The problem is that such a password is usually very hard to remember. To make random passwords more memory-friendly, another method is sometimes used, i.e., random words or syllables are used instead of random letters. We can also find users who prefer to use mnemonic phrases that have random letters as the initial of each word.

Sometimes personal mnemonics are used. These involve things memorable to you, but not to others. Take this password for example: IvLwIw16. It derives from “I visited London when I was 16.” It’s the user’s own memory and no one else’s. That makes it easier to remember and harder for others to crack.

A number of software programs have now been developed to generate random passwords containing a varied set of characters that include lowercase and uppercase letters as well as numerals. These are hard to crack or guess because of an optional combination of lower and upper case letters and numbers. Some of the programs give you the option to generate fixed or variable length passwords. Sometimes a high quality pseudorandom number generator is used which offers five methods for generation: a) automatic generation where the user can choose the contents, b) masked generation where the user specifies patterns describing the password, c) dictionary mode where it grabs random passwords from a file the user specifies, d) pronounceable mode for passwords that are easy to remember and e) character list mode for generating passwords comprising a chosen list of characters.

All modes can choose lower-case, upper case or mixed-case letters. Some generators create purely random passwords while the others generate passwords based on wordlists. Although more secure, purely random passwords tax the user’s memory. Passwords based on wordlist, on the other hand, is more memory-friendly.

Passwords provides detailed information on Best Passwords, Change Passwords, Password Generators, Password Protection and more. Passwords is affiliated with Electronic Keyboard.

About Asbestos
Sunday 8 February 2009 @ 12:55 am

Are you looking for some inside information on asbestos? Here’s an up-to-date report from asbestos experts who should know.

The name asbestos refers to a natural mineral that was used in construction and in many home items in the past. This material possesses heat-resistant qualities that made it useful for construction where it was employed as fire proofing and weather resistant material. Some years ago it was discovered that asbestos has serious health consequences and its use was prohibited. The main problem appears when the material is damaged, when it is cut and when the material is to be disposed of.

There are three varieties of asbestos: white, brown and blue. This material appears in the form of hairs or fibers and their characteristics differ according to the type of asbestos. Blue and brown asbestos were prohibited in 1986 and the use of white asbestos was reduced in the same year. Nevertheless, all the types of asbestos are still present in home and work places.

It’s really a good idea to probe a little deeper into the subject of asbestos. What you learn may give you the confidence you need to venture into new areas.

When talking about the risks asbestos poses to health, it is important to highlight that the danger arises when the fibers becomes airborne and thus they can be easily ingested or inhaled. But not all fibers represent a hazard. Long fibers and small ones are generally eliminated when coughing or breathing. They do not stay in the lungs. On the contrary, there are fibers of certain size or that belong to a particular type of asbestos that insert in the lungs and are responsible for the development of mesothelioma or other asbestos related diseases.

In conclusion, all type of asbestos have to be managed with care and in all cases the necessary protective measures should be taken.

Now you can be a confident expert on asbestos. OK, maybe not an expert. But you should have something to bring to the table next time you join a discussion on asbestos.

Everywhere Glaciers Are Thawing at a Frightening Rate
Sunday 1 February 2009 @ 10:53 am

Everywhere glaciers are melting at a swifter rate than at any time since records commenced, said The Observer. Glaciologists from the International Glacier Monitoring Service, which tracks 32 glaciers in ten mountain areas, estimate that from 1850 to 1972 glaciers shrank at a average pace of 30 centimeters per year. From 1973 and 2003 reductions climbed to 50 – 95 cm a yr. Since then the average has made up greater than one metre per year. Last winter saw the biggest reductions til now of 1.2 meters.

Across the globe glaciers are receding at the least as fast as those glaciers in this small group with potentially fatal results for close by towns. In the immediate future there could be increased floods, and in the not so distant future, water supplies could disappear, resulting in critical water shortages.

Chamonix village, with its great number of glaciers, the consequences of climate change and the receding of glaciers will be keenly felt. Perhaps this is why several firms, such as Ski Europe, and individuals seem to be more knowledgeable of the issues and are therefore attempting to take steps to restrain their carbon output. Hopefully it’s not too tardy to halt the consequences of climate change and guarantee an environment for our kids.
