Bedtime Story

You need to always question what I write.

Or even better, cross verify it with much better references using the device you hold in your hand.

In today's world, being ignorant is really an option (one can be knowledgeable without great education or without having several letters before or after his or her name).

So what were the developments that lead to the knowledge of relative abundance of elements in the universe?

One of the greatest help we apes got was with the discovery or invention of mass spectrometry.

The men who invented this device were 2 (at least as claimed by the Western English speaking world).

1. Englishman Francis William Aston in 1919

2. Canadian American Arthur Jeffrey Dempster in 1918.

Just imagine as Europe was involved in one of their bloodiest slaughter and carnage, these men were quietly working in their labs devising an instrument that could sort out atoms and ions based on their charge to mass ratio.

(I wish to emphasize yet again that even though atoms are a fact, we using the term atomic theory till date.)

Aston in 1900s like so many others was studying current in gas filled tubes.

In 1910 at the age of 33, he moved from Birmingham to the Cavendish Laboratory in Cambridge under the great J. J. Thomson.

Cathode rays and electrons had just been discovered then.

At the same time, 2 German physicists:
Eugen Goldstein
Wilhelm Wien
sometime in 1886 discovered a new form of rays which in German they called:
"Kanalstrahlen".

These were positively charged.

Wien had discovered that these rays could be deflected by magnetic fields.

Aston went one step further.

He subjected these new rays to both electric and magnetic fields.

In doing so, he could separate different ions by their ratio of charge/mass.

By 1919, Aston had achieved 2 feats:

1. He showed that atoms of a single element could have different isotopes thereby establishing as fact that even non radioactive elements have isotopes.

2. He had invented the first mass spectroscope.

The Canadian Dempster had greatly improved on it, greatly increasing its accuracy in identifying compounds by mass of elements in a sample.

This was a gigantic step to our understanding of nature.

We shall look in detail at the mass spectrometer in nights to come.

Good night mon ami and my fellow cousin ape.
