Well, it is not really an invention, I know. My theme is to tell the stories of inventions and discoveries that changed the world as we know it. So, here we go. In the 9th of April it is the turn of the letter “H” (of course not counting sunday). I searched many lists of inventions starting with the letter H but nothing seemed too significant or world-changing. So, I moved on to discoveries searching for a world-changing discovery. And I didn’t need to search about anything because it came out of no where in my mind just like that. The name of the 3rd most important gas on earth (Hydrogen).
It is agreed that the most important gases for our lives comes in this order: Oxygen, Carbon Dioxide and …… Hydrogen. Of course every element in the universe matters, God created them all for purposes. Each element is important in a way. But there are elements if absent our lives would be different from what it is now. Other elements if absent there would be NO LIFE at all. So, we sort them that way.
This time we will reverse the article normal order. In each invention I was telling the story and then explaining why this invention was too important to study its history. But now, I will start with the importance and uses of Hydrogen to attract you to read the rest, as it is a discovery not an invention.
Without Hydrogen, life as we know it would be impossible; you could argue that, without hydrogen, we could not float in water; because – no water!.Into every litre bucket of water; nature has compressed more than 1250 litres of Hydrogen and over 850 litres of Oxygen !
I will list some examples of Hydrogen here that may be you know some of them and maybe not:
The sun is 75% hydrogen by weight, making it a fairly good sample of this element.
Deuterium is hydrogen where each nucleus has a neutron as well as the standard proton in it. This makes it basically twice as heavy as normal hydrogen. Heavy water is water (H2O) in which the two hydrogens are replaced by two deuterium atoms. The total molecular weight of heavy water is 20 instead of 18 for normal water, so it’s really not all that much heavier.
Deuterium is not radioactive, and for most chemical purposes it is a virtually identical stand in for hydrogen, which means you could probably drink this water and suffer no ill effects. Heavy Water is used in many applications like Nuclear Magnetic Resonance, Organic Chemistry, …. etc.
Hydrogen is a main element in the formation of many rocks.
The universe is about 75% hydrogen by weight: Good enough to count as an element sample.
When the earliest motor vehicle was invented, late in the eighteenth century, in Europe, the only fuel available to run in the elementary engine on that vehicle was … Hydrogen.
In 1671, Robert Boyle discovered and described the reaction between iron filings and dilute acids, which results in the production of hydrogen gas. In 1766, Henry Cavendish was the first to recognize hydrogen gas as a discrete substance, by naming the gas from a metal-acid reaction “flammable air”. He speculated that “flammable air” was in fact identical to the hypothetical substance called “phlogiston” and further finding in 1781 that the gas produces water when burned. He is usually given credit for its discovery as an element. In 1783, Antoine Lavoisier gave the element the name hydrogen (from the Greek ὑδρο- hydro meaning “water” and -γενής genes meaning “creator”) when he and Laplace reproduced Cavendish’s finding that water is produced when hydrogen is burned.
In Egypt we have a proverb that says “God puts his secret in his weakest creatures”. That proverb applies perfectly on Hydrogen. It is the simplest and most abundant element in the universe..
So, I thought it is too important to tell the short story of this discovery which changed our vision of the universe in a way.
