A chemist is a scientist trained in the science of chemistry. Chemists study the composition of matter and its small-scale properties such as density and acidity instead of large-scale properties like size and shape. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, reaction rates, and other chemical properties. Chemists use this knowledge to learn the composition, and properties of unfamiliar substances, as well as to reproduce and synthesize large quantities of useful naturally occurring substances and create new artificial substances and useful processes. Chemists may specialize in any number of subdisciplines of chemistry. Materials scientists and metallurgists share much of the same education and skills with chemists. Chemical engineers are concerned with the physical processes necessary to carry out industrial reactions (heating, cooling, mixing, diffusion etc) and to separate and purify the products, and work with industrial chemists on the development of new processes. The roots of chemistry can be traced to the phenomenon of burning. Fire was a mystical force that transformed one substance into another and thus was of primary interest to mankind. It was fire that led to the discovery of iron and glass. After gold was discovered and became a precious metal, many people were interested to find a method that could convert other substances into gold. This led to the protoscience called Alchemy. The word chemist is derived from the New Latin noun chimista, an abbreviation of alchimista (alchemist). Alchemists discovered many chemical processes that led to the development of modern chemistry. Chemistry as we know it today, was invented by Antoine Lavoisier with his law of Conservation of mass in 1783. The discoveries of the chemical elements has a long history culminating in the creation of the periodic table by Dmitri Mendeleyev. The Nobel Prize in Chemistry created in 1901 gives an excellent overview of chemical discovery in the past 100 years. Jobs for chemists usually require at least a bachelor's degree, but many positions, especially those in research, require a Ph.D. Most undergraduate programs emphasize mathematics and physics as well as chemistry, partly because chemistry is also known as "the central science", thus chemists ought to have an all-rounded knowledge about science. At the Master's level and higher, students tend to specialize in a particular field. Fields of specialization include biochemistry, organic chemistry, inorganic chemistry, analytical chemistry, theoretical chemistry, quantum chemistry and physical chemistry. Postdoctoral experience may be required for certain positions.

1. History Of Glowsticks
August 10, 2008
The glowstick was invented over 40 years ago by Edwin Chandross, a chemist at Bell Labs. Glowsticks use chemical energy to product light. At the time it was quite a remarkable achievement because either electrical mains or battery were the energy sources for most light producing devices.
Based on Chandross' work, many scientists took on the task for further refining the process. However, the patent for Chemical Light Device is registered in the US Patent in the name of inventor Richard Taylor Van Zandt.
Glow sticks can be used just once and come in different sizes in translucent plastic ... (read more)

7. Chelation From The Beginning
May 02, 2008
The term chelete was first used by Dr, Gilbert T Morgan in 1920. The literal meaning of this term is derived from the Greek word chele means claw of a lobster. It works like a caliper to grab something. But the systematization of the chelation theory was done by French- Swiss chemist Alfred Werner. He propounded the theory of coordination of compounds which is known as chelates. He explained the theory that how metals com together to form organic molecules. It became the foundation of chelation chemistry.
This theory was followed by the industrial production of EDTA chelation in 1920s. It... (read more)

8. How Diabetics Can Live to be 100 Years Old
March 25, 2008
As a medicinal chemist, I’m often asked, "How can I live to be a 100 years old?" My answer is simple, "Learn to control blood sugar and insulin."
The biggest threat to longevity is high blood sugar and insulin. Known as type II diabetes - or more accurately insulin resistance - it has become a nationwide epidemic that steals 11 to 20 years from a person’s lifespan. It is one of the main culprits behind depression, obesity, heart disease and even cancer. Understanding two simple facts about the pandemic killer may help you avoid it - and live to be 100 years old rather than 65 or 70... (read more)

9. Mother Nature’s Total Immune Boosting Breakthroughs
March 25, 2008
As a drug chemist, I used to fear going to work. I risked numerous health hazards – like being exposed to a cancer causing reagent and even losing my wedding ring to a chemical drain. Cancer is bad, but having your wife feel like you are being careless about your marriage is worse. Unknown to her, I was washing off DNA twisting molecules that burned my skin and eyes while they vacuumed the air from my lungs. My ring fell off somewhere between stripping off my clothes, pulling the lab’s evacuation button, and yanking the emergency shower cord. I naively assumed that these were necessary r... (read more)

12. The Secret Behind Making Perfume
February 11, 2008
Perfumery, that is the art of making perfume, is quite an ancient art that was first started in Mesopotamia as well as in Egypt, sometime during the 2nd millennium, BC.
During those days, perfumes were mostly made using spices such as coriander, almond, bergamot, etc and various kinds of herbs too. Surprisingly, they did not use flowers to make perfumes during the early days of perfume making. The use of flowers for perfume making was discovered by a Persian chemist and doctor, who first experimented with roses, to manufacture perfume.

18. Medical Advancement? Please?
January 03, 2008
I’m fascinated with the advancements of science in general but particularly so with the increase in our understanding of human physiology. Medical science is fascinating to me given the complexity of the human creature. At one point I aspired to a career in the medical sciences but settled into the role of a mere chemist instead. I think it’s mostly because I had a desire to experiment and I cannot imagine poking at a human just to see how they twitch being met with fanfare and adoration. In fact, I’m pretty sure that’s why there is malpractice insurance- to protect the doctors from the sc... (read more)

25. The Vacuum Flask alias Thermos
October 09, 2007
Everyone has heard the term “Thermos”, but most don’t know much about why it works and where it came from. A good “Thermos” keeps your food or beverage hot or cold for an extended period of time.
Over a century ago in 1892 Sir James Dewar, a chemist and physicist, invented the vacuum flask. They were called Dewar Flasks. The first vacuum flasks commercially made were by a German company named Thermos in 1904. In 1963 the word “Thermos” was declared a genericied trademark. Today most do not ask for a vacuum flask, but instead ask for a thermos. Simply put, a thermos is a vessel whi... (read more)
