## Karl Scheele

### Died while testing his discoveries

Scheele was a brilliant pharmaceutical chemist who discovered many chemical elements-Oxygen, Molybdenum, Tungsten, Manganese and Chlorine. He also discovered a process very similar to pasteurization. Scheele had the habit of taste testing his discoveries and, fortunately, managed to survive his taste-test of hydrogen cyanide HCN. But alas, his luck was to run out: he died of symptoms strongly resembling mercury poisoning.

## Robert Bunsen

### Blinded himself in one eye

Robert Bunsen is probably best known for having given his name to the Bunsen burner which he helped to popularize. He started out his scientific career in organic chemistry but nearly died twice of arsenic poisoning. Shortly after his near death experiences, he lost the sight in his right eye after an explosion of Cacodyl Cyanide. These being excellent reasons to change fields, he moved in to Inorganic Chemistry and went on to develop the field of spectroscopy.

## Sir Humphrey Davy

### Disaster, disaster & disasters

Sir Humphrey Davy, the brilliant British Chemist and inventor, got a very bumpy start to his science career. As a young apprentice he was fired from his job at an apothecary because he caused too many explosions! When he eventually took up the field of chemistry, he had a habit of inhaling the various gasses he was dealing with. Fortunately this bad habit led to his discovery of the anesthetic properties of Nitrous Oxide. But unfortunately, this same habit led to him nearly killing himself on many occasions. The frequent poisonings left him an invalid for the remaining two decades of his life. During this time he also damaged his eyes in a Nitrogen Trichloride explosion permanently.

### Suffered Chronic Poisoning

Thanks to the injury to Sir Humphrey Davy’s eyes, Faraday became an apprentice to him. He went on to improve on Davy’s methods of electrolysis and to make important discoveries in the field of Electromagnetism. Unfortunately for him, some of Davy’s misfortune rubbed off and Faraday also suffered damage to his eyes in a nitrogen chloride explosion. He spent the remainder of his life suffering chronic chemical poisoning.

## Marie Curie

In 1898, Curie and her husband, Pierre, discovered radium. She spent the remainder of her life performing radiation research and studying radiation therapy. Her constant exposure to radiation led to her contracting leukemia and she died in 1934.

## Examination Strategies : Tactics & Tips

Every student or graduate knows how hard the first experience of passing exams is. Preliminary preparation starves the nervous system and the physical condition of the human body, however, the exam itself is always a stressful situation, which requires a candidate a great manifestation of mental and physical abilities. Therefore, just the knowledge of a subject is not enough for…

## Classical Theory of Raman Scattering

The classical theory of Raman effect, also called the polarizability theory, was developed by G. Placzek in 1934. I shall discuss it briefly here. It is known from electrostatics that the electric field $E$ associated with the electromagnetic radiation induces a dipole moment $mu$ in the molecule, given by $\mu = \alpha E$ …….(1)…

## Entropy and Disorder

In science, we look for patterns to discover nature’s laws. What is the pattern common to all spontaneous changes? To find a pattern, it is often best to start with very simple examples, because then the pattern is likely to be more obvious. So let’s think about two simple spontaneous changes — the cooling of a hot metal and the…
