What field of electrical engineering most relates to chemistry? and how does it relate to chemistry?
What field of electrical engineering most relates to chemistry? and how does it relate to chemistry? THANKS!
Actually, most of them.
1) In the power and process industries, electrical engineers work closely with chemical engineers.
2) All types of batteries.
3) Electronic components are all made from chemical compunds.
4) Corrosion is electrochemical in nature.
5) Process control
Which most? I would say (1). Steam power plants require constant steam quality monitoring and chemicals to meet quality standards.
But (5) is perhaps, where chemical and electrical engineers work the closest. A control loop is a blend of electrical, mechanical and process chemical steps.

A Marketable Computer Science Degree May Mean Specializing
Computer Science degrees are offered at hundreds, if not thousands of colleges across the country for a good reason; the demand for computer experts has never been higher. In fact, the need for computer scientists will continue to rise through at least 2015 according to the United State Department of Labor’s 2006 report on career growth.
What many people don’t realize is that part of the hiring increase of the future in the computer sciences area includes a trend toward more specialization. According to the Department of Labor’s Occupational Outlook Handbook, “The explosive use of computers has created a high demand for specialists to provide advice to users, as well as for day-to-day administration, maintenance, and support of computer systems and networks.”
When considering a career in the computer sciences, you should consider Colleges and universities that offer a variety of programs under the umbrella of either computer science degrees or information technology degrees, as the terms are interchangeable. Look to see if the school offers just one degree or if they offer several different specializations. Ideally, a school should offer at least three bachelor’s degrees that are more tightly focused, such as Computer Programming, Network Engineering or Database Administration, all of which would fall under Management Information Systems (MIS).
The Department of Labor’s report also recommends that anyone pursuing a computer science degree be sure to pursue ongoing education after a degree is achieved and a job is landed. Because of the rapidly changing face of computing, it’s essential that anyone working in this industry continue to build on his education by getting additional certifications and adding new skills every few years.
Find a college that also offers ongoing certifications that are licensed by leaders in the industry, such as Microsoft’s various programs, Cisco’s CCNA and Net+. Knowing that you can return to your alma mater for continuing education is a great way to ensure that your certification courses will be of the same high caliber as your undergraduate classes.
Outlook is Good for Properly Trained Specialists
The Occupational Outlook Handbook of 2006 is adamant in its belief that there is no end in sight to the increasing need for computer specialists. It lists numerous specific titles that require intense training in particular areas, including:
Computer Systems Analysts
Computer Programmers
Software Engineers/Developers (consistently growing as businesses continue to require new, highly specialized software to suit their needs)
Database Administrators
Computer Support Specialists
Data Communication Analysts/Webmasters (increasingly popular in retail as more businesses open online, virtual storefronts)
Computer Systems Administrators (expected to be one of the fastest growing Careers in the next five years)
Cyber Security (a relatively new field that has taken off like a rocket as online terrorism and corporate espionage has increasingly threatened corporate computer systems)
The best computer science degree programs will not only include a wide range of specializations, but will also offer different types of degrees as well. Ideally, a college should offer Associate’s, Bachelor’s and Master’s Degrees along with various types of certification. This will help guarantee that the teaching staff is current on all the latest advancements and also giving you the most educational options. With computer training being in such high demand, you may even find that you can get a great job with one degree and get reimbursement through your employer to pursue a higher-level degree.
With so many reasons to go into the computer sciences and so many highly specialized career options available, pursuing one of the many specialized computer science degrees now offered is a great investment in your future.

How does chemistry apply to economics and the commercial importance of chemicals like heterocyclic compounds?
I am interested in knowing what is the relation between chemistry and economics. That is aproject given to me by a professor, since I am doing a course in sciences along with a degree in finance. Kindly help.
Nearly all drugs contain heterocycles as do many other chemical entities that are sold. Some of th elargest corporations in the world rely on small molecules for their cash flow: Exxon, Dupont, Pfizer, Dow, Merck, Glaxo, etc.
In pharma there is a very fine line between what a consumer can be charged before the claims of "drug company rape" and other options are found with the ever present complication of government nullification of patents. There is the cost-benefit arguement with drugs and even in early drug testing, some sort of separation must be made between the cost of the drug and the benefit obtained.
Encourage Your Child To Use His Mind With A Science Kit
Parents are always looking for things that will spark their child’s imagination while giving them a valuable education at the same time. The next time you’re considering what to buy for your child, consider a science kit. Remember that children love to explore and learn and the field of science allows them to do both.
Many parents might hesitate to buy this type of kit for their child because they are worried about them being dangerous or that a child might be too young to truly appreciate and learn their intended lessons. Another anticipated problem is trying to replace the different substances they might contain when they have run out and it will be relegated to the pile containing other broken and no longer used toys. Fortunately, there are four science based kits that are both child and parent friendly.
Ant Farm
Ant farms have fascinated children for years. It’s a fun way to watch nature at work and provides hours of entertainment. Children will get to learn about the lives of ants and how they interact with the earth and each other. Of course, some parents might worry that the ants will escape and use the house as their farm, but while a few might get out, that should not be a concern.
Chemistry Sets
Chemistry sets are another fun way to learn about science and chemicals. The new versions of these kits are colorful and suitable for younger children and the supplies are easily replaced. For the older child, there are more advanced sets available. These contain substances that allow the older junior scientists to create other chemicals like hydrochloric acid. They are worrisome for the parents but the children love them.
Elephant Nose Fish
The Elephant Nose fish actually emits electrical charges. It is truly a wonder of nature and science. The child can listen to the sounds of the electric emissions with the use of a piezoelectric earphone. You can purchase one of these at your local Radio Shack or other stores that carry electronics. They are very easy to feed and take care of. The important thing to remember is to make sure that the top of the aquarium is closed tightly, so that they won’t be able to jump out. Another important thing to keep in mind is that they need to be kept in groups of three to five fish. These fish will keep the whole family entertained.
Crystal Growing Kit
Crystal growing kits have been around for years. They are very inexpensive and it’s fascinating to watch the gemstone colored crystals grow
Consider buying your child a science kit to teach them and educate them at the same time.

How is chemistry done in eating bread and drinking water?
I really need it! Where is chemistry in chewing the bread and drinking the water?
i think it’s more related to biology…..
um…..u can consider dis as bio-chemistry
bread contains rich carbohydrates. Salivary gland secrets saliva which contains an enzyme called amylase. Amylase breakdown 5% of carbohydrate in the bread during your chewing and they will be converted into maltose.
Pancreas secret pancreatic juice and further starch n maltose into glucose. Glucose can be use to generate energy instantly.
Chemical energy carried by the bread has changed into chemical energy of our body.
water is an universal solvent. It provides a medium for substances to carry out chemical reactions inside cells.
Say sugar molecules and salt particles, they are stored in cell sap(cytoplasm).
(juz skip dis part if u find it to complicated^^..i am actually doing revision for my chem test tmr)→[[[Sugar = C6H12O6, which is simple molecular structure. Salt(NaCl sodium chloride) = giant ionic structure. The bond between Na n Cl is weaken by water. Soo...these two substance can dissolve efficiently in our body.]]]
If we drink sufficient water everyday, food granules will be absorbed and react faster and provide us nutrion.

Top 10 Science Discoveries in 2006
Science is nothing other than discovery and understanding things. To some it’s a study to others an adventure. One of the earliest of sciences it fails to loose its place as the number one in research and development. Every year great minds mull over the year that has been and list what the top 10 or 20 science discoveries for the year are.
In 2006 leaders among science discoveries were:
1. A chance to know mankind’s primordial past by the study of comet particles brought back to earth by NASA’s spaceship Stardust. The comet particles are said to contain gases and dust from the formation of the solar system 4.6 billion years ago. Around 150 scientists all over the world are involved in the study of and discovery from the comet remains.
2. Paleontologists have found in Nunavut in Canada a 375 million year old fossil that bridges the gap between land and aquatic creatures. Names Tiktaalik roseae or fishapod the fossil may well solve many mysteries of evolution.
3. For years mankind has attempted to reach the core of the earth. In April 2006 ateam of the Integrated Ocean Drilling Program was able to drill a mile into the ocean crust and collect intact samples of the crusts various layers which includes the deepest layer known as gabbro.
4. A Russian Grigory Perelman resolved a complex Mathematical problem known as Poincare’s Conjecture. For this achievement he was awarded the prestigious Fields Medal by the International congress of Mathematicians.
5. The discovery of nano creatures in acid sludge in mines could lead the way to understanding life forms that survive under extreme conditions. Organisms that live in mine sludge oxidize iron to get sustainable energy.
6. An antiquarian book written in 1650 contains important information on traditional healing methods used Indonesia.
7. Genetic studies revealed that human and chimpanzee ancestors could have inbred more than 6.3 million years ago.
8. A crash between two galaxies enabled scientists to detect invisible dark matter for the first time.
9. Ocean research teams discovered that a large area of the South Pacific had almost no sea floor sediment.
10. Research showed that starlings could learn and recognize grammatical patterns called recursion once thought to be uniquely a human language trait.
In an attempt to understand himself and life mankind has continuously studied all aspects of life past and present. Physics, math, biology, chemistry, anthropology, nutrition, medicine, molecular biology and astronomy among many other fields contribute to understanding man’s evolution and the creation of a sustainable future. It is study, brainstorming, and debate that led to discovery. Every year experts review the year that has been. As always lists are not stringent and a matter of choice and taste. It is not what leads but the knowledge of what has happened that is important.
The World Wide Web hosts thousands of websites that bring science closer to lay persons and knowledge on the internet promotes learning and an understanding of how science works.

What is the best chemistry book for a novice chemist?
I am a college graduate (BA) with little science background. I am interested in expanding my knowlege of chemistry, physics, astronomy – all of the exact sciences. I think chemistry is the best place to start a solid foundation. (If I am mistaken, I’m open to suggestions) What are some concise, yet readable books that I should choose?
To be honest, and I’m not insulting you in any way…But pick up "Chemistry for Dummies"…Or even "The Complete Idiots Guide to Chemistry". I’m telling you, when I had trouble with chemistry, these books spelled everything out clearly. They’re rather inexpensive, as compared to some Chemistry text books you could buy online. The books helped me pass Chem 1 and 2 with straight A’s. Now I’m on Organic 1 and these books still prove to be a wealth of information. Hope this helps…
