Louis Pasteur devised the first vaccines for humans, thereby saving millions of lives by long term prevention of disease. He also challenged the myth on spontaneous generation, thereby setting the stage for modern biology and biochemistry.
We know that all matter is made up of atoms. Unless we know how atoms function, we cannot go deeper into scientific possibilities. So understanding the structure of atoms is fundamental not only in chemistry, but also to almost every field of science and technology.
How can we find out how old a dinosaur fossil is? Or an ancient shipwreck discovered at the bottom of the ocean?
Willard Frank Libby came up with the method known as Radiocarbon Dating, a process that revolutionized the way we look at artifacts and document world history.
Cholera and Tuberculosis were two of the most dangerous killer diseases in the late 19th century. Cholera was nicknamed 'King Cholera' because no one seemed to be able to cure it. Tuberculosis was known as the 'White Death' because sufferers vomited up white matter as their lungs disintegrated.
Meet the man who made a breakthrough in the fight against these diseases, Robert Koch.
Today we are able to genetically engineer plants to produce various useful chemicals. But did you know that this ability traces back to Helen Michael, who was among the first to study the chemical properties of plants?
Different kinds of reactions happen between chemicals. We know that metals give electrons to non-metals to form salts. But many compounds exist, which are formed by non-metals alone. It was Gilbert Lewis who explained how these compounds are formed.
While today many women are famous scientists, till just a few centuries back, they weren't allowed to do scientific research or even learn science. Emilie du Chatelet was one of the first women to break the barrier and become a practising scientist.
Every time you use a computer (such as in reading this article), you make use of the element gallium. It is an important component of semiconductors. Did you know it was Francois Lecoq who discovered it?
We read a little about Hermann von Helmholtz, the founder of thermodynamics, last week. But it was really Josiah Gibbs who helped it develop into a great science, which is followed by all chemists today. Let's know more about him.
