Archimedes of Syracuse, who lived in the Third century B.C. was the greatest mathematician and mechanical engineer of his time. He was a pioneer in his day in the domain of mechanics, and a venerable philosopher. Hiero, King of Syracuse, charged him with the task of ascertaining whether a crown made for him by a local goldsmith was of pure gold or of an alloy of gold and some baser metal. It took him many days to find a solution to the problem set him. According to his custom he went to the public baths and entered the water with the problem of the gold crown on his mind. As he did so, he observed the changing level of the water, and after some thought splashed out of his bath, shouting at the top of his voice, 'Eureka!' This means 'I have found the solution'. Later he put his discovery to a practical test, and found that he could with certainty formulate his findings in the proposition that a body plunged in a fluid loses an amount of its weight which is equal to the weight of fluid displaced by it. This was to lead to many subsequent discoveries, but it enabled him to tell the king how much pure gold was in the composition of his crown. `Eureka!'—he had the thrill of making a great scientific discovery.
The early Christians—Andrew, John, Peter, Philip and others, when they met Jesus of Nazareth, made the great discovery that He was the Saviour of the world, the Christ their Saviour. 'We have found the Messias,' said Andrew, using the same Greek word for 'found' that Archimedes had used for his discovery.
Sir James Simpson, the discoverer of chloroform, was asked as he neared the end of a life in which he had made many scientific discoveries, `What is the greatest discovery you ever made?' He replied, `The greatest discovery I ever made was that I was a lost, guilty sinner, and that Jesus Christ, the Saviour of sinners, is my Saviour.'
(Job. 11. 7; 23. 3; Isa. 55. 6; John 1. 41, 45; 4. 29; 1 Tim. 1. 15)
Lord Kelvin, when asked by a student which of all his wonderful discoveries he considered the most valuable, startled the questioner by replying, `To me the most valuable of all the discoveries I ever made was when I discovered my Saviour in Jesus Christ.'
(Acts 22. 7, 8; Gal. 1. 15, 16)
