Put it simply Chemistry is the study of matter and the way matter changes.

The word Chemistry comes from an ancient Egyptian word khemeia. Khemeia was an Egyptian art which occurs in various Egyptian groups that was connected to mummification. Later along the history, its practices included things such as dyeing, metallurgy and glass making.

Although the ancients knew of copper, silver, gold, tin, lead, iron, carbon and sulphur, they did not know that these are elements. To them, they follow the teachings of the 5th century BC Greek thinker and philosopher Empedocles and popularized by Aristotle. To them, matter was made up of four elements – the earth, air, fire and water. To them this classification made sense because after all, earth is not a solid, water is not a liquid, air not a gas and fire not an energy. Of course, to use people that study «Science» and call ourselves Scientists, that sentence does not make sense to us.

When Greek thinking encountered the Egyptian art of khemeia, probably during Alexandria about 300 BC, alchemy was born and it flourished for two thousand years. Alchemy combined mysticism and many general scientific experimentation. The alchemists became obsessed with the search of immortality and trying to turn any kind of metals into gold. They were the first to make general use of many of the chemicals we use today, such as strong acids – sulphuric acid, hydrochloric acid and nitric acid. They also developed many experimental procedure such as filtration, dissolution of solids and simple distillation.

The alchemists had built up a list of practical scientific information but they did not understand why things happened. Before our current understanding of chemistry, there are 3 more important concepts that were developed and followed:

1. Appreciation that scientific progress begins always with experiments and onservations
2. An understanding of what an element is – Robert Boyle and Antoine Lavoisier concluded the elements are the simplest unit that cannot be further broken down.
3. Development of the Atomic Theory – Greek philosopher Leucippus and Democritus proposed about this theory but was not successful. John Dalton is the one that came in to prove its existence.

And with that, the Russian Dmitri Mendeleev (1834 – 1907) came in to construct the world famous The Periodic Table which are recognised as the most important system of classification in Chemistry.

Many people talked about teaching Chemistry, Sean Chua Lian Heng lives it. He is a passionate Chemistry Coach based in Singapore, Southeast–Asia and one of the most dynamic, powerful and humorous speakers in Asia. He has empowered hundreds of students to experience Chemistry learning with a difference, and unlock the secrets to achieve the grades they truly deserve.

He specialized in helping students through The 1ST in Singapore GCE 'O' Level Chemistry Intensive BootCamp and Organic Chemistry Mastery Workshop using Accelerated Learning Techniques. His 10 years of coaching experience has equipped him to understand the true reasons why students are not able to perform well in Chemistry, and has allowed him to structure his teaching methodology to cater to different levels of learners. Sean has produced many outstanding students who have achieved marvelous 'O' Level Chemistry results under his wings of patient guidance and coaching.

His chemistry coaching methodology emphasizes on the vital 4 'A's and has a 100% proven track record to help students to improve their chemistry grades:

• Associations with Everyday Life

• Applications in Real Life & Industrial Examples

• Analogies for abstract Chemistry Theories

• Accelerated Learning Techniques

Having acquired knowledge in the different fields of Chemistry during his Polytechnic and University days Sean is able to communicate experiences, real life Chemistry observations, apt analogies – all this to simplify the Chemistry Concepts for students to grasp and remember in an easier manner. He also has several years of experience as a Chemist and Technical Specialist for the fast–growing Research Chemical Industry. Through his extensive experiences in the Chemical Research arena, he is constantly talking to aspiring scientists, researchers as well as Deans, educators in local universities and schools – such updated research and market trends are always the highlights when students asked about how each Chemistry topics relate to real life situations.

The early Bronze Age in the Aegean, also known as the Early Cycladic period, is divided into sub–periods, corresponding primarily to the advances in pottery techniques and design.

By the first period of the Bronze Age (Halcolithic Age), the Cyclades had already developed a culture with its own distinct features.

The expansion of shipping and trade between 2800–2700 BC generated the growth of ports, which became small urban centers. Besides Phylakopi on Milos, other centers were Akrotiri on Santorini, Aghia lrin on Kea, Parikia on Paros, and so on. Fortified settlements also appeared, such as at Kastri on Syros, Panormos on Naxos, Kynthos on Delos, Halandriani on Syros, and so far on.

But these settlements did not last long and came to violent ends. As a result, artistic creation in the Aegean was suspended and the settlements did not evolve into city–states.

After 2000 BC, Minoan civilization made inroads into the Cyclades. This infiltration affected not only pottery making, architecture and metallurgy, but also writing, religion and systems of measurement.

The eruption of the Santorini volcano, in c. 1 650 BC, made an impact on developments in the Aegean. Here was initial period of decline after the eruption, but a revival soon followed.

The settlement of Phylakopi on Milos (Phylakopi III) was rebuilt on top of the ruins of Phylahopi II. Evidence shows that during this period the Cyclades invaded by the same peoples, mostly from mainland Greece, who had invaded Crete alter the eruption of the Santorini volcano. Phylakopi Ill was destroyed and Phylakopi IV became a fortified Settlement. Minoan Crete, like the Cyclades, was strongly influenced by Mycenaean civilization.

Because of their geographic position, the Cyclades, in particular, became a bridge for Mycenaean trade activities.

The Mycenaeans took advantage of the islanders' shipbuilding knowledge and sailing experience which resulted in further growth of the Cyclades during the late Bronze Age.

City of El Paso lies in the U.S state of Texas. 5th largest in Texas and 22nd largest city of USA, El Paso comes second to San Diego and California if size of all US cities on the Mexico border is considered. This is the most worth visiting destination on the Mexico border. Equipped with all sorts of things of visitor's interest, this city is a complete travel destination in itself. It has all the elements to satisfy the intent of every visitor in the city.

Home to the University of Texas, El Paso is an important academic center too. This university was founded in the year 1914. This is the transformed status of Texas State School of Mines and Metallurgy. Some army establishments like Fort Bliss, a major United States Army installation, can be found here too. The city is divided into two sections by the Franklin Mountains that extend into El Paso from the north. Both the sections have stunning travelers delight.

Talking of attractions, you will find plenty of them because of the rich cultural and historical heritage. Viva El Paso is the annual returning musical show which literally displays the wealthy cultural and historical aspect of the city through dance, dramatic scenes, narration and songs. The story is based on the early Indian settlement which takes you through Spanish conquest, Mexican domination and the wild South–West. McKelligon Canyon Amphitheater is the place where this musical show is performed. The massive crucifix on top of Mt. Cristo Rey is a fantastic site to be at.
