Jobs in the science industry are becoming the fastest growing in our lifetime. Technological advances in many fields are leading to new types of science and therefore new fields of study. A career in the field of science does require an education, most often a four year degree but two year degrees can begin your career and let you advance in your studies as you go along in your career. These are some jobs in the better known fields of science that you may find of interest:

Biology – One of the fastest growing fields in the science industry is the field of biology, which is growing by leaps and bounds as technology and the current laws in the United States change. For a job in biology you will need to have a field of study chosen and then choose a good 2 or 4 year college with a good plan of study. Biology encompasses many fields such as the medical field, animal studies as well as field research and academia. Biotechnology is a growing field that expects greater growth in the coming decades. According to a 2003 study biologists with less than one year experience had a starting salary of approximately $33,000, while those with more experience and who are in the fields of life sciences have a starting salary closer to $60,000. A job in the field of Biology is a job that you can enjoy for the various aspects of study.

Chemistry – Jobs in the chemistry field also vary by specialty such as chemical engineering, biochemistry and even teaching at high school level and on a college level. Chemistry is a four year degree with heavy study loads but they have a rewarding future. According to the National Association of Colleges and Employers, in July of 2007 the starting salary for graduates with a bachelor’s degree in chemistry was on average $41,500 a year and those in the highest end of the degree field were being paid just over $100,000.

Forensic Sciences – Due to the popularity of the various crime dramas on TV these days the field of forensic sciences has exploded. This field actually encompasses many sub fields of science such as chemistry, biology, and even anthropology. Jobs in forensic sciences have actually made the science industry cool again, as NASA once did in the late 60’s and early 70’s with the trips to the moon. Ideally you will have had a good deal of chemistry and biology in high school , this will help in your four year degree in whatever job you have chosen. Also, a real love of science and technology is a plus. The starting salary for someone on the forensic science field varies due to many factors but a 4 year degree holder can expect to start out at $30,000 and analysts with many years of experience can reach as high as $70,000.

Aeronautics and Space – With the Space Agency set to begin trips to Mars soon, this is one job that will have many openings in so many different areas. Space studies is a relative new comer to the science industry really only having been around since the 1950’s but it is a fast growing field that actually houses all the various forms of scientific study as well as the specific study of flight. Careers within this field can have starting salaries of no less than $57,000 for a person with under one year experience all the way to $108,000 for those who have more than 20 years experience

Be careful not to throw the baby out with the bath water if you criticize electronic games for kids, or even ban them from your children, because the right ones can provide a very positive educational experience.

Educators have long taken advantage of children’s passion for games, and especially for computer games. The usual approach is to overlay some educational content onto a familiar game format. Educational computer games must be played in an entertaining way.

A type of game that easily combines amusement and learning are strategy games. Educational experts have always known that learning is most effective when students enjoy the experience, and even more so when it is interactive.

Therefore it was to be expected that educational innovators would harness the immense popularity of electronic games for kids to learning, and no bad thing that they are.

Students can be introduced to the common technological tools, techniques and styles in computer games development. Activities will include how to modify classic computer games as well as design and develop original computer games. Students had four computer periods per week with electronic games. The computer room was also full during lunch periods and many students stayed for two hours or more after school.

Children learn eye hand coordination and mental strategy through the right choice of games. Some are even educational and they can learn about history and culture as in the age of empire game.

Children are becoming addicted to the games, it is often said, and “they are into it body and soul.” It might also be added that; “Their body language is tremendous and shows how well they concentrate everything the have upon zapping the enemy and that is why electronic games for kids are so popular. “

There’s nothing constructive in those games beyond developing an ability to concentrate.

But, there are also still many other good electronic games for kids which are also educational video games, but the kind the kids like most tend to be the kind they are about Martians coming in that ‘have to be killed’, and so forth.

This is why parental guidance and involvement expecially with young children is absolutely essential, to guide the you and give the child “values” by which they will in future be able to moderate their on use of the internet and their use of computers generally.

With higher education tuition increasing at double digit year
over year percentages an effective saving plan for your kid’s
education is becoming much more important than it has been
before. Most families will discover that their future higher
education costs will be much more than they have saved for their
kid’s education. This leaves many kids to be faced with
obtaining financial aid to pay for a portion of their college
education. The goal of this article is to explore the pros and
cons of 4 common investment options when saving for college.
This article will also explore why some of these options are
better than other when considering a portion of your kid’s
education may be funded by financial aid.

529 College Savings Plan: – A 529 college savings plan is a
fairly new investment option for college saving. It allows just
about anyone to save for college. There is a long list of
benefits of a 529 college savings plan, but perhaps the most
important is that your earnings grow tax free if you use it for
qualified education expenses. Additionally, the maximum amount
you can contribute to a 529 plan can go as high as several
hundred thousand dollars depending on your State. In the event
you do not use the funds for college, you can still withdrawal
your earnings, but you will have to pay taxes and a 10% penalty.
The penalty will be waived if your child receives a scholarship,
or your child becomes disable or dies.

529 plans can typically be purchased through a broker or mutual
fund company, but a disadvantage is that investment choices can
sometimes be limited. Since qualifying for financial aid is
based on a calculation that considers your kids assets, another
big benefit of a 529 college savings plan is that the money in
the plan is classified as a parents assets so less that 6% of
the value counts against your kid’s financial aid eligibility.

Uniform Gifts to Minors Act/Uniform Transfers to Minors Act

(UGMA/UTA Custodial Account): – The benefit of a UMGA/UTA
Custodial Account is that there is no limit on the contribution
and it is easy to set up at most financial institutions.
However, the limitations far outweigh the benefits. The first
limitation of a UMGA/UTA Custodial Account is that these types
of accounts offer very little tax advantage. If your child is
under 14, only the first $800 of income is tax free, the next
$800 is taxed at your child’s tax rate and after that there is
no tax benefit at all. The other big limitation is that the
account has to be set up in your child’s name. As a result, if
your child needs financial aid all of the assets will be
reviewed at a 35% rate. Therefore, this type of account is not
advisable for those who may need financial aid.

Coverdell Education Savings Account (CESA): – A Coverdell
Education Savings Account is very similar to a 529 college
savings plan. The main difference is that with a Coverdell
Education Savings Account you can only contribute $2000 per
child and to qualify your adjusted gross income must be less
than $110,000 if single and less than $220,000 if married filing
jointly. The account is classified as a parent’s asset so less
that 6% of the value counts against your kid’s financial aid
eligibility.

In the end, parents should consider planning for college to be a
highly important process. The above 3 alternatives can make this
process much more easy and financially sound.

Industrial inorganic chemistry includes subdivisions of the chemical industry that manufacture inorganic products on a large scale such as the heavy inorganics (chlor-alkalis, sulfuric acid, sulfates) and fertilizers (potassium, nitrogen, and phosphorus products) as well as segments of fine chemicals that are used to produce high purity inorganics on a much smaller scale. Among these are reagents and raw materials used in high-tech industries, pharmaceuticals or electronics, for example, as well as in the preparation of inorganic specialties such as catalysts, pigments, and propellants. Metals are chemicals in a certain sense. They are manufactured from ores and purified by many of the same processes as those used in the manufacture of inorganics. However, if they are commercialized as alloys or in their pure form such as iron, lead, copper, or tungsten, they are considered products of the metallurgical not chemical industry.

The chemical industry adds value to raw materials by transforming them into the chemicals required for the manufacture of consumer products. Since there are usually several different processes that can be used for this purpose, the chemical industry is associated with intense competition for new markets. It is made up of companies of different sizes, including several giants that are engaged in the transformation of some very basic raw materials into final products, as well as medium-size or small companies that concentrate on very few of these steps. The closer to the raw material, the larger the scale of operations; such “heavy” inorganic chemicals are usually manufactured by continuous processes. At the other extreme in terms of scale are the firms that manufacture “specialties,” mostly in batch processes, from “intermediates” that correspond to chemicals which have already gone through several steps of synthesis and purification.

Basic chemicals represent the starting point for the manufacture of inorganic industrial chemicals. They are usually one step away from the raw materials and are produced on a very large scale employing continuous processes. The unit price of these products is relatively low, and producing them cheaply and efficiently is a major concern for the companies that manufacture them. Sulfur, nitrogen, phosphorus, and chloralkali industries are the main producers of basic inorganic chemicals, and they will often sell them to other industries as well as using them in the manufacture of their own end-products. The basic principles for their production and major uses are indicated here for each of these industries.

Inorganic chemicals produced on an industrial scale can be easily identified. Many of today’s large companies started as producers of inorganics, but as coal—and especially petroleum—became important sources of raw materials; they were integrated into the product chain. Inorganic chemicals such as chlorine are used in the manufacturing of several chlorides, including PVC and hydrochloric acid.

There are many different sources of raw materials for the manufacture of inorganic chemicals. Very few of them are found in their elemental form. Sulfur is a notable exception. It occurs in underground deposits and can be brought to the surface by compressed air after it is melted by superheated steam. However, increasing quantities of sulfur are recovered from petroleum and natural gas (where they occur as impurities). Air contains molecular nitrogen and oxygen. They may be separated by liquefaction and fractional distillation along with inert gases, especially argon. Salt or brine can be used as sources of chlorine and sometimes bromine, sodium hydroxide, and sodium carbonate, whereas metals such as iron, aluminum, copper, or titanium as well as phosphors, potassium, calcium, and fluorine are obtained from mineral ores. Saltpeter was once an important source of nitrogen compounds, but today most ammonia and nitrates are produced synthetically from nitrogen gas in the air. Recovery and recycling provide increasing amounts of some metals. As environmental concerns increase, these operations will probably become an important source of materials used in the manufacture of certain inorganic chemicals.

The origins of the chemical industry can be traced to the Industrial Revolution. Sulfuric acid and sodium carbonate were among the first industrial chemicals. “Oil of vitriol” (as the former was known) played an important role in the manipulation of metals, but its production on an industrial scale required the development of materials that would resist attack. Sodium carbonate was obtained in its anhydrous form, “soda ash,” from vegetable material until the quantities produced could no longer meet the rapidly expanding needs of manufacturers of glass, soap, and textiles. This led the Royal Academy of Sciences of Paris, in 1775, to establish a contest for the discovery of a process based on an abundant raw material, sodium chloride, and to Nicolas Leblanc’s method for the preparation of soda by converting salt into sulfate: 2NaCl + H2SO4 → Na2SO4 + 2HCl; followed by conversion of the sulfate to soda with charcoal and chalk: Na2SO4 + 2C + CaCO3 → Na2CO3 + CaS + 2CO2

Although he did not win the prize, Leblanc’s process is associated with the birth of industrial chemistry. The industrial production of chemicals was usually based on running reactions that were known to yield the desired products on much larger scales. Success in these endeavors lay much more in the experience and skill of their practitioners than the application of solid chemical principles. This led to serious problems of control and the generation of noxious by-products. The introduction of the Leblanc process in the northwest of England led to a general public outcry against the dark and corrosive smoke that covered the surrounding countryside. The Alkali Act, passed in response in 1863, represents the first legislation that established emission standards.

Sulfuric acid was an essential chemical for dyers, bleachers, and alkali manufacturers. Its production on a large scale required the development of lead-lined chambers that could resist the vapors which were formed when sulfur was burned with nitrates:

SO2 + NO2 + H2O → H2SO4 + NO, and NO + 1/2O2 → NO2

This process was wasteful and emitted corrosive gases. It improved only in the mid-nineteenth century when towers to recycle the gases were finally introduced. The transportation of sulfuric acid was dangerous, and alkali manufacturers tended to produce their own as a result. This marked the beginning of the diversification and vertical integration that are characteristic of the chemical industry. Sulfuric acid was also used in the manufacture of superphosphates, which were produced as fertilizers on a large scale by the mid-nineteenth century. By that time, a solution was found for the complex engineering problems that had hampered the use of the alternative process to produce soda:

NH3 + H2O + CO2 → NH4HCO3

NaCl + NH4HCO3 → NaHCO3 + NH4Cl

2 NaHCO3 → Na2CO3 + H2O + CO2

Ernest Solvay, a Belgian chemist, designed a tower in which carbon dioxide reacted efficiently with solid salts. The Solvay process had enormous advantages over the Leblanc process: It did not generate as much waste and pollution; its raw materials, brine and ammonia, were readily available (the latter from gasworks); less fuel was used, and no sulfur or nitrate was involved. In spite of its higher capital costs, it was rapidly adopted and soon became the major source of alkali.

Another major process used in the manufacture of inorganic chemicals is the catalytic conversion of nitrogen and hydrogen to ammonia. The German chemist Fritz Haber first synthesized ammonia from nitrogen and hydrogen in 1909. Four years later, together with another German, Carl Bosch, he modified the process for the commercial production of ammonia. The Haber (or Haber–Bosch) process represented a technological breakthrough since it required a very specialized plant to handle gases at high pressures and temperatures.

Sulfuric acid has long been the chemical that is manufactured in the largest quantities on a world scale. Its production is often linked to a country’s stage of development, owing to the large number of transformation processes in which it is used. Sulfuric acid is manufactured from elemental sulfur. Mining was the main source for this element, which was obtained from sulfide-containing ores or in very pure form from underground deposits by the Frasch process (injection of superheated steam and air into drillings and the separation of the mixture that rises to the surface). The large-scale consumption of petroleum and natural gas has changed this scenario since sulfur occurs as an impurity in most fossil fuels and must be removed before the fuels are processed. These fuels are presently the main source of sulfur, and their relative importance tends to increase with more rigorous controls on emissions. Sulfuric acid is manufactured as: 2SO2 + O2 → 2SO3   ; SO3 + H2O → H2SO4

Since the reaction of sulfur with dry air is exothermic, the sulfur dioxide must be cooled to remove excess heat and avoid reversal of the reaction. Most plants use reactors with various stages in order to cool the stream for the catalytic step. Conversion by a vanadium pentoxide catalyst deposited on a silicate support is the critical step in the process, in which the gaseous stream is passed over successive layers of catalyst. The gas mixture is then passed through an absorption tower. Oleum, the product, is a concentrated solution of sulfuric acid containing excess sulfur trioxide.

As an inexpensive source of acid, a large amount of the sulfuric acid that is produced is used for the manufacture of other mineral acids. It is also used to produce sulfates, such as ammonium sulfate (a low-grade fertilizer), sodium sulfate (used in the production of paper), and aluminum sulfate (used in water treatment), as well as organic sulfates (used as surfactants). Sulfuric acid is also a good catalyst for many reactions, including the transformation of ethanol into ethylene or ethyl ether.

In general, chemicals containing nitrogen are manufactured from ammonia produced by the Haber process. Since molecular nitrogen is inert, its reaction with hydrogen requires very severe conditions and a catalyst. An iron catalyst is used. High pressure favors the formation of products, but an increase in temperature will shift the equilibrium in the opposite direction. Plants will thus operate under conditions that represent the most favorable balance between operating costs and capital investment. Energy consumption is very high, and its cost is an important component along with the starting materials. Nitrogen is easily obtained from air and hydrogen and can be produced by the shift reaction: CO + H2O → CO2 + H2 or from hydrocarbon reforming: CH4 + 2H2O → CO2 + 4H2

Further stages are required to assure conversion and to remove carbon dioxide or carbon monoxide from the gas mixture. A mixture of ammonia and synthesis gas (CO + H2) results from the reaction with nitrogen so the two must be separated and the synthesis gas recycled.

Most of the ammonia that is produced is employed as fertilizer or used to manufacture other fertilizers, such as urea, ammonium sulfate, ammonium nitrate, or diammonium hydrogen phosphate. Ammonia is also used in the Solvay process, and it is a starting material for the manufacture of cyanides and nitriles (which are used to make polymers such as nylon and acrylics) as well as aromatic compounds containing nitrogen, such as pyridine and aniline. The other source of nitrogen compounds in the chemical industry is nitric acid, obtained from the oxidation of ammonia: 4NH3 + 5O2 → 4NO + 6H2O; 3NO + 3/2O2 → 3NO2 and 3NO2 + H2O → 2HNO3 + NO

The first reaction is run over platinum-rhodium catalysts at around 900°C (1,652°F). In the second and third stages, a mixture of nitric oxide and air circulates through condensers, where it is partially oxidized. The nitrogen dioxide is absorbed in a tower, and nitric acid sinks to the bottom. Nitric acid is mainly used to make ammonium nitrate, most of it for fertilizer although it also goes into the production of explosives. Nitration is used to manufacture explosives such as nitroglycerine and trinitrotoluene (TNT) as well as many important chemical intermediates used in the pharmaceutical and dyestuff industries.

The world’s major source of phosphorus is apatite, a class of phosphate minerals. Commercially, the most important is fluoroapatite, a calcium phosphate that contains fluorine. This fluorine must be removed for the manufacture of phosphoric acid, but it also can be used to produce hydrofluoric acid and fluorinated compounds. Phosphoric acid is the starting material for most of the phosphates that are produced industrially. It is obtained from the reaction of the apatite mineral with sulfuric acid. Silica is present in the mineral as an impurity, and it reacts with hydrofluoric acid to yield silicon tetrafluoride, which can be converted to fluorosilicic acid, an important source of fluorine. More than half of the phosphoric acid that is produced by the reaction of phosphates with sulfuric acid is converted directly to sodium or ammonium phosphates to be used as fertilizer; thus, purity is not a concern.

For products that require high purity, such as detergents and foodstuffs, phosphoric acid is produced from elemental phosphorus (at about four times the cost). An electric furnace operating at 1,400–1,500°C (2,552–2,732°F) is used to form a molten mass of apatite and silica that reacts with coke and reduces the phosphate mineral:

2Ca3 (PO4)2 + 6SiO2 + 10C → P4 + 6CaSiO3 + 10CO

Concentrating phosphoric acid leads to polyphosphoric acid, a mixture of several polymeric species, a good catalyst and dehydrating agent. Polyphosphate salts are used as water softeners in detergents or as buffers in food. Small quantities of elemental phosphorus are used to make matches, and phosphorus halides to prepare specialty chemicals for the pharmaceutical and agrochemical industries.

Industries producing chlorine, sodium hydroxide (also known as caustic soda), sodium carbonate (or soda ash) and its derivatives and compounds based on calcium oxide (or lime) are usually included under the chloralkali category. As both sodium hydroxide and chlorine have a common raw material, sodium chloride, they are produced in quantities that reflect their equal molar ratio, irrespective of the market for either product. Since they are produced by electrolysis, they require a cheap source of brine and electricity:

2NaCl + 2H2O → 2NaOH + Cl2 + H2

Most processes are based on the electrolysis of a sodium chloride solution, but some plants operate with the molten salt. Three different cell types are used in electrolysis in water: mercury cells, diaphragm cells, and membrane cells. Membrane cells are replacing the other two types in modern units, but it may not be economically feasible to convert older plants.

Sodium hydroxide and sodium carbonate are alternative sources of alkali, and their use has followed the availability of raw materials as well as the efficiency of processes developed for their production. Both require sodium chloride and energy and, if limestone deposits are also available, sodium carbonate may be produced by the Solvay process. Limestone consists mainly of calcium carbonate and can be used to produce calcium oxide (or quicklime) and calcium hydroxide (or slaked lime); the oxide may be obtained by heating (1,200–1,500 ° C or 2,192–2,732 ° F) limestone, while the hydroxide, which is more convenient to handle, is obtained by adding water to the oxide: CaO + H2O → Ca(OH)2

Its principal use is in steelmaking, but it also goes into the manufacture of chemicals, water treatment, and pollution control. In the Solvay process, calcium carbonate and sodium chloride are used to produce calcium chloride and sodium carbonate with ammonia (which is recycled) as a medium for dissolving and carbonating the sodium chloride and calcium hydroxide for precipitating calcium chloride from the solution.

As sodium carbonate may be mined directly, its use may be preferred over a manufactured product. It is used mainly in the glass industry. Sodium silicates may be derived from sodium carbonate and in their finely divided form, silica gel, may be used in detergents and soaps. Sodium hydroxide has many different uses in the chemical industry. Considerable amounts are used in the manufacture of paper and to make sodium hypochlorite for use in disinfectants and bleaches. Chlorine is also used to produce vinyl chloride, the starting material for the manufacture of polyvinyl chloride (PVC), and in water purification. Hydrochloric acid may be prepared by the direct reaction of chlorine and hydrogen gas or by the reaction of sodium chloride and sulfuric acid. It is used as a chlorinating agent for metals and organic compounds. In certain regions of the world, there are salt deposits or brines that have been enriched by bromine. Commercially, bromine may be extracted by treating the brines with chlorine and removing it by steam. Bromine is used in water disinfection; bleaching fibers and silk; and in the manufacture of medicinal bromine compounds and dyestuffs.

Titanium dioxide is by far the most important titanium compound. It can be purified by dissolving in sulfuric acid and precipitating the impurities. The solution is then hydrolyzed, washed, and calcinated. Alternatively, ground rutile is chlorinated in the presence of carbon and the resulting titanium tetrachloride is burned in oxygen to produce the chloride. Titanium dioxide is found in nature in three crystal forms: anastase, brookite, and rutile. Its extreme whiteness and brightness and its high index of refraction are responsible for its widespread use as a white pigment in paints, lacquers, paper, floor covering, plastics, rubbers, textiles, ceramics, and cosmetics.

In the early 1990’s the Internet exploded. The World Wide Web took us on the fast paced information super highway and brought innovations our grandparents couldn’t fathom. Currently more than half of American households are connected to the Internet.

We are raising the first generation of children that have full access to information using the World Wide Web. The educational benefits of the Internet are incredible. However along with all the benefits comes a whole new set of dangers. We need to be reminded of protecting our kids online continually or find out away to allow them to surf the web for school, fun and other educational purposes safely. The FBI recently revealed that 100% of kids today will encounter a sexual predator online. This was a shocking revelation to all of us here at Zyzyrgy.

Recently a friend of ours launched a new program called Children’s Educational Network and one of the products they developed was a Kids Safe Browser. His goal is help kids be safe on the internet and also help educate them along the way. As they were developing the program they realized without any safe guards in place our kids could be in danger while learning online. Their next step was to develop tools on their site to help teach financial education through the use of games. Another friend of ours, Loral Langemeier, is also working with him to create a Loral’s Kids browser to teach your children about money and finance based on her teachings. Many years went into the development of this unique and parent approved browser that keeps our kids safe while learning online. The specialized browser is an exciting tool both for kids and parents to stay protected from the hate, violence and pornography prevalent on the Internet today.

The high-tech browser is currently FREE! That’s right, there is no risk or cost involved to you for providing your kids with the safest and most fun web surfing environment ever created.

Here are just a few of the many benefits of the Browser:

Kids Surf Safe – Prescreened “Include List” of Sites Just for Kids!
Provides Loads of Online FUN – You can access over 10,000 websites with just one click! This includes thousands of sites helpful for doing homework, plus sites featuring educational games and other cool content.

If you are interested in pursuing a career in science, then you will want to know about all the great opportunities you have to choose from. There are literally hundreds of different jobs in this line of work, and it’s important that you think about specifically which aspect of science you want to work in. Some people choose to go into marine biology, the study of organisms under water. If you have a curiosity about working with different chemicals, then you might want to be a chemist of some sort. Whichever science position you choose, you should make sure to take your time in deciding. You should also enjoy the position you hold and find it interesting, because the more intrigued you are about the work you do, the better you will be at it.

One of the fastest growing science careers right now is a forensic science, and if you are interested in getting a position like that, then you will want to know how to go about doing it. Forensic science is becoming popular because of the opportunities it gives to work with cutting edge technology and the chance to do something truly meaningful with your life. You will get to apply the skills and training you have received in school to this job and work closely with the legal system, helping to put away criminals and bring them to justice.

There are also many physics jobs that you can take as well, if you are interested in that particular sector of science. Many people that end up finishing school with a science major of some sort decide that they actually want to go into teaching. It is yet another growing career choice that can lead to great things. You will be able to take what you have learned and pass it on to future generations who will then use that knowledge to find interesting and challenging careers of their own. When you really think about it, there is an almost endless list of science jobs you can take. Before you start school for a science career however, you will want to take the time to think about what kind of a science job you want to have.

This decision will ultimately determine what program you go into and what courses you will take. Of course there are all the general science requirements, however if you decide that you are interested in marine biology or physics, then you will be taking more glasses geared specifically towards those subjects. You should also know that in a science major, you will almost certainly incur quite a bit of math courses that will be required, even if the job you want doesn’t necessarily require those skills. It always helps to have a well-rounded education when going into virtually any line of work, including science.

A few days ago I was pleased to meet an old friend, who I have not seen for a long time. Proudly, he told me about his graduation in sub-nuclear physics, full marks with honors. Unfortunately, mines were sour congratulations, because the conversation ended up on the same old dispute between humanists and scientists, with an exemplary statement on our different curriculum: “If my son studied humanities, I would strangle him with my own hands”. A though expressed roughly and summarily, without any further clarification. However, it helps us understanding how frivolous and not very useful humanities are considered among some technical professionals. In particular, I perceived in his words a twisted reputation of arts, identified with the realm of dreams, of irrationality and uncontrolled emotions and studied without a scientific methodology.

The divorce between humanities and sciences is the result of western culture and its distinctive education, excessively specialist and fragmentary. However, if we look carefully at the two macrocosms of human knowledge, we will realize that they work under common methods and aims. Consider, for instance, fictional and poetic literature: there are two, main approaches to their reading. The first is a reading taken out of its context, free from external information, which allows a personal and exclusive interpretation of the text, according to each reader’s background. This is the case of contemporary poetry which, by exaggerating its visual element and operating through images, can be interpreted in a number of ways. The second is an analytic reading which, according to the historic, social and literary context of the text, investigates the author’s original message: an unambiguous interpretation, as happens with the regular literary studies carried out at school.

In my opinion, the approaches mentioned are similar to those provided by a scientific training: there is basic research, applied research and engineering. If we consider the field of chemistry, the chemist and the chemical engineer share similar studies, but pursue very different aims. The chemist is a pure scientist, committed to setting and verifying the universal principles of chemistry, but without practical application. The chemist discovers new reactions and connections between elements, in the same way an analytic interpretation of the text provides new information about the author and his age. The chemical engineer, on the contrary, dedicates to find a practical application of the laws set by his colleague, and therefore interpret them in a personal way according to his own background of experiences. As a consequence, engineering an out-of-the-context reading address to the world of subjectivity. However, this does not mean working in absence of logic and understanding: as the engineer must deal with laws that cannot be ignored, I must subordinate myself, while writing this text, to the principles of linguistics, in order to deliver a precise message.

In addition, there are many other examples pointing out the connections between humanistic and technical sciences: there is Chomsky’s modern linguistics and its generative grammar, which establishes laws regulating the language production of a precise time and place, not based on an abstract grammar, but on the opinions of native speakers and, therefore, turning frequently to statistics; statistics also allowed us to discover a certain regularity in the demographic trend in history, an harmonic alternation between periods of war and famine and periods of peace. In the same way, it is important to remark the strict relationship between philosophy, ethics in particular, and the recent findings in the field of genetics, and between sociology and architecture. The diatribe, therefore, is just the attempt of separating two universes which are not so different, and pursue the same purpose, the progress of human kind.

All parents want their children to grow up having lots of fun. Parents provide opportunities for their kids to participtate in sports and clubs of all kinds. If they are able, parents fill their home with toys and games to keep their children entertained and happy with things that are safe for kids to do. Parents should, however, see to it that their children have more than just fun. Childhood should be a time filled with learning and trying new things. Parents can combine their child’s desire for fun with their need for learning by choosing educational games.

Educational games are great because they are just what their name suggests: games that provide children with fun and promote their education at the same time. Parents who take seriously their responsibility to help their children learn new things and grow in important knowledge will be pleased to know that educational games are becoming increasingly available and popoular for kids of all ages.

Think about your children’s ages and the unique educational needs they currently have. A three year old should be learning different things than an eight year old. If you are unsure of what educational games to buy for your kids, do a little research to see what kinds of needs your kids have and then find educational games to fit those needs. Talk to your children’s teachers to get good ideas of the needs that each of your kids have. Teachers will likely be able to suggest specific skills and goals that you can work on at home.

Educational games are a great way for parents to get involved in educating their children. Consider substituting educational games instead of a sporting event or an after school club that your kids are involved in. Find ways to balance the things your kids love to do with the things your kids need to be learning. In no time you may find that your kids choose educational games on their own once their learn how fun the games can be. It is a great thing when kids begin to request that educational games be a part of family time or a game night. Families can spend hours of quality time together laughing as they learn.

You can find educational games at many stores or online. Many companies are creating a wide variety of educational games for every budget. The next time you are tempted to pick up the latest video game for your child or to enroll them in an after school club, consider instead teaching your children to love learning by purchasing educational games for them.
