The Great Scientific Discoveries – Part 1

ScientificDiscovery2

‘The joy of discovery is certainly the liveliest that the mind of man can ever feel.’

                                                                                                           Claude Bernard

The latest quest to find a vaccine against the corona-virus made me think about so many scientific discoveries that have allowed humanity to develop in leaps and bounds. I won’t write in chronological order because there are thousands, but I will start with the discoveries relevant to us now.

VACCINATION

Protection against infectious diseases by inoculation with germs themselves goes back to antiquity. The word is derived from the Latin vaccinae, meaning ‘of the cow’. The word vaccination appeared around 1880, used for the first time by Pasteur, who knew of the work of the Englishman Jenner, who had immunised patients against cowpox and common smallpox. The idea of ‘vaccination’ of this sort was practised in China in the 10th century by a Taoist monk, whose name has not survived. It was based on the principle that you treat evil with evil. To think that this was thought of eleven centuries ago is astonishing. Vaccination then took place not by scarification but by implantation of a pad carrying some attenuated germs in one nostril.

Vaccination also had been used in Turkey since time immemorial. Possibly as a result of the experimentation of the first known toxicologist in history, Mithridates VI, King of Pontus (north of modern day Turkey), who claimed that one could be immunised against poisons by regularly absorbing small quantities of them. The Turks ‘vaccinated’ against smallpox by extracting traces of the contents of the pustule from mild cases of the disease and injecting them into healthy people. This was a rather risky practice and some people died from the effects of the vaccination. I recommend that you don’t try this at home.

Re the chains above, I suspect it was hard to come by volunteers!

The Jenner vaccination method was introduced into France by the Duc de la Rochefoucauld-Liancourt. Meanwhile, the notion of attenuated germs made progress. It was obvious that one could not inject the actual germs of a disease against which one wanted to immunise, for fear of triggering the disease itself. It was recognised that inoculation with an attenuated germ could help the organism to recognise a germ and defend itself against it. This is why this principle of attenuation was implemented by Pasteur in his preparation of a vaccine against rabies. In 1885, Pasteur was presented with a 9-year-old child, Joseph Meister, who had been bitten by a rabid dog. Althought not a doctor, Pasteur responded to the challenge: he used the vaccine on the child with successful results. Modern vaccination had been born.

The only important modification made subsequently was the introduction of vaccines obtained  through genetic engineering. These were brought into use in 1983, the first one commercially produced being the vaccine against hepatitis B in 1986.

THOMAS  EDISON’S  LAMP

Thomas Edison is one of the best-known and most prolific inventors of all time. He was granted 1,093 US patents. At his family home in Port Huron, Michigan, home-schooled 12-year-old Edison set up his first laboratory in his bedroom. When he was 14, Edison built a working telegraph at home. By the age of 16, he was working as a telegraph operator and for the next five years he travelled, working at a number of different telegraph offices in several different cities. At the age of 21, he decided to devote all his time to inventing.

In 1873, he invented the ‘Quadruplex Telegraph’, the rights to which he sold to Western Union. With the proceeds , Edison bought in 1876 34 acres of land in the countryside of  Menlo Park, New Jersey. In his new property he set up a full research and development laboratory – the first of its kind in the world. In Menlo Park he set out to improve the recently invented telephone.

The dynamo room at the first Edison electric lighting station opened in 1882 at Pearl Street, New York, United States, engraving, 19th century.

The most important invention to come out of Menlo Park was the light bulb. Edison demonstrated the new technology in December 1879, lighting the workshop in a public demonstration. His success with electric light led him to work on a system to distribute electric power and to set-up a bulb making factory. Edison patented the system in 1880, and by 1882, he set up a power station at Pearl Street, New York. He continued to invent many more ideas, like Kinetoscope, the first device for showing moving pictures.

Edison died in 1931. After his death, US President Herbert Hoover encouraged Americans to turn off their lights for one minute, in tribute to the contribution made by America’s greatest inventor.

Around the year 850 BC, a young Ethiopian goat herder, Kaldi, was astonished to see that his goats were not sleeping at night. Watching them closely, he discovered that they were grazing on the red fruit of an unknown tree. Having tasted the fruit, he found that they had a stimulating, exciting effect on him too. The drink called coffee, a name derived from the provence Kaffa in Ethiopia, where coffee is cultivated, was discovered around the time Kaldi discovered that his goats were insomniac.

All coffee trees belong to the genus Rubiaceae. Coffee originated in Ethiopia and is an evergreen shrub whose cherry-like fruits contain the coffee beans.

Complete plants were not exported until the 15th century, destined for Arabia. Coffee houses were very popular in Mecca, then in Egypt and Turkey. Coffee was later introduced to the East Indies, West Indies, South America, and Africa. In England the first coffee shop was set up in Oxford in 1651 by an Armenian man, named Harutiun Vartian, at the parish of St Peter-in-the-East. Today, on the same side there is a cafe-bar called The Grand Cafe.

In London, the first coffee house opened later the same year.

It also reminded me of the extraordinary story about the way coffee was first introduced to Europe. It was during the siege of Vienna by the Ottoman Empire led by Suleiman the Magnificent. A Polish man, Jerzy Franciszek Kulczycki, a traveller and an explorer living at the time in Vienna, decided to help King John Sobieski to repel the siege. As he spoke eight languages, including Turkish to perfection, he dressed in Turkish clothes and during the night left Vienna for the Turkish camp. Talking to the men in the camp he was able to find out what was planned. Back in the city, he was able to warn the king and prevent problems during the attack. After the siege was destroyed and the Turks repelled, the King asked him what he would like to have as a reward. To everyone’s surprise, Kulczycki asked for a huge number of bags of brown beans. No one could think what they were for. In a short time, Kulczycki opened a shop/drinking establishment, called The Blue Bottle where he served an aromatic drink – coffee made tastier to European likings by the addition of milk and honey. Everyone, including the King, loved the beverage, and that is how coffee conquered Europe.

 

CHARLES  BABBAGE AND  HIS  ANALYTICAL  ENGINE

26 December 1791  –  18 October 1871

Babbage

Babbage’s design inspired the pioneers of the modern computer. Long before the invention of the modern computer, Babbage, a mathematical genius, designed machines that would carry out complicated mathematical operations. He invented the world’s first programmable computing device but he also contributed to the development of business efficiency and railway travel.

BabbageEngine

As a child, Babbage was extremely inquisitive. In his autobiography, he wrote that whenever he had a new toy, he would ask his mother ‘What’s inside it?’, and would always break things open to find out how they worked. This curiosity gave him an understanding of mechanisms and machines.

TrinityCambridge

In 1810, he went to study mathematics at Trinity College, Cambridge University. At the time , mathematicians and engineers relied on books filled with tables of numbers to carry out calculations. In 1812, Babbage moved college, to Peterhouse. In the library there, he realised that there were large numbers of mistakes in the numerical tables, and that they were down to human error.

Babbage envisaged a machine that would be able to calculate these tables at speed and remove the risk of human error.

In 1822, Babbage presented to the Royal Astronomical Society a proposal to build a calculating machine. The society granted Babbage money, and he hired an engineer to oversee the job. In a workshop close to his house, the engineer, Joseph Clement, a skilled toolmaker and draghtsman, set to work.

BabbageEngine2

Babbage’s Analytical Engine was the first known design for a mechanical general all-purpose computer. Although never finished because of a dispute between Babbage and the engineer, the concepts it utilised in its design were at least 100 years ahead of his time. Programs and data would be inputted using punched cards. Output consisted of a printer, a curved plotter and a bell. The machine memory would be capable of holding 1000 numbers of 50 decimal digits each. The programming language it was to use was very similar to that used in the early computers 100 years later, well before Alan Turing’s concept.

In 1827, his father, his wife and one of his sons died, and Babbage stopped work and took time to travel in Europe. While he was travelling, he dreamed up a more general calculating machine, which would be able to follow a set of instructions. Babbage envisaged a machine that would have a printer that would output the results. By 1835, he had produced the first of many designs for an ‘Analytical Engine’ – the forerunner to the modern programmable computer. His design was expressed in 500 large engineering drawings, a thousand pages of engineering calculations and thousands of pages of sketches. In 1991, the Science Museum in London followed Babbage’s design and constructed it; in 2005, they added a printer that also had been part of Babbage’s original design. Both machines worked perfectly.

Babbage’s designs inspired the pioneers of the modern computer and this is what he is remembered for, but he also had a significant influence on other fields. While travelling in Europe in the 1820s,  Babbage toured factories and studied the manufacturing process. In 1832, he published a book called ‘On the Economy of Machinery and Manufacture’, which was the beginning of studies into the efficiency of business and industry – what is now called operational research. He applied his methods to mail in Britain, and the result was the world’s first cheap and efficient national postal system.

Postbox

He also studied the efficiency of the railways, which were in their infancy at the time. He invented a special carriage filled with equipment that would record the bumps in the tracks during a journey, and a device to move objects off the track ahead of the train – affectionately called a cowcatcher. The concept was used on trains around the world.

Through his inventions, Charles Babbage is recognised worldwide as GENIUS.
