It being Sunday, I think a parable would be quite in order. The following story was told to me by a well-known Afrikaans churchman.
The congregation had been invited to a attend a Bible quiz between two teams consisting of the elders of the congregation and Oom Danie was very surprised (so he said!) that he had not been chosen to partake in the quiz, so he visited the parson and aired his misgivings. He reminded the parson that he had been a serving member of the church council for very many years and had always taken part in all the discussions of the council and that he thought that omitting a prominent member of the council could be regarded as a slap in the face. So, to keep the peace, it was decided to increase the quiz teams by two more members.
It all went very well until the parson, acting as quiz master, asked Oom Danie a question:
Parson: "Oom, What is the distance between Dan and Beersheba?"
Oom Danie: "Parson, what do you mean by this question?"
Parson: "Oom, as you know, Dan was in the very north of Israel and Beersheba was more or less the most southern town in Israel. An answer to the nearest 50 kilometers would be acceptable."
Oom Danie: "Parson, do you want to tell me the Dan and Beersheba were places, I always thought they were man and wife, just like Sodom and Gomorrah!"
The moral of the story is: Do not think too much of yourself!

THE AGE OF THE EARTH
In the paper today I found a very interesting piece! Two professors at the NW University took on a colleague who had written (my translation!) in a journal: "Mankind did not come from any animal and all species can not be coupled to each other." The two who replied stated: "Such a short and sweet conclusion denies a lot of scientific results of evolutionary biology." (Again my own translation!) This little bit of news sparked a question in my mind: How old is the Earth?
I consulted some scientific books on astronomy and found very interesting facts!
1. A Greek philosopher, Xenophanes (560 – 478 B.C.) had already pointed out that the earth must be very old as he had seen seashells embedded in rocks on mountains, which meant that the sea level must have been much higher in the past and that this type of change could only occur over long periods of time.
2. A church historian, Eusebius of Caesarea (260 – 340 AD) used statements in the Bible to calculate the birth of Abraham and decided that it took place in 2 016 B.C.
3. Some Jewish rabbi's went even further and used the genealogy given in Genesis to calculate the creation of the earth and arrived at a figure of 3 761 B.C., still being used by the Jews as this is the year 5 670 in their calendar.
4. Then an Anglican bishop, James Ussher (1581 – 1656) calculated from data in the Bible that the earth was created 4 004 years before the birth of Christ which makes the earth (and the rest of the universe) 6 014 years old.
Yet many prominent persons were not satisfied with an answer of "about 6 000 years" and the first to say so openly and in detail was a French naturalist, Georges de Buffon (1707 – 88). He spent fifty years writing a 36 volume encyclopedia on natural science and in the fifth volume, published in 1778, he gave his ideas on the development of the Earth and theorized that the sun and another heavy body had collided and thus formed the earth which in time cooled down and animals, and finally, mankind appeared on earth. He also imagined a form of evolution though degeneration – some horses degenerating into donkeys and some men into apes.
I rather fancy the last one as I know quite a number of people who behave like apes!

THE AGE OF THE EARTH - CONTINUED
A geologist, James Hutton (1726 – 1797), stated that it is evident that some rocks were formed by sediments compressed in layers, other rocks were certainly formed by volcanic action and exposed rocks were worn down by the action of wind and water, and so on. He also pointed out that this process was slow and also assumed that this process had probably always been going on at the same slow rate and that the Earth must be much older that the 6 000 years or so postulated by previous claims. He published this in a book Theory of the Earth in 1785 and is commonly regarded as the "father of geology".
And then, in 1896, Antoine Henri Becquerel (1852 – 1908), discovered radio-activity! Physicists soon found that the heavy metals, uranium and thorium, gave off radiations and were giving off heat continually, because atoms were breaking down. Ernest Rutherford (1871 – 1937) showed in 1904 that particular varieties of atoms broke down at fixed rates and this led to the discovery that in any such a reaction, half of the atoms breaking down would do it in a certain time interval, say x years and half of what remained would break down in an additional x years, and so on, and that period is called the "half-life". It was also found that elements could consist of different isotopes, a term that means that the different forms still had the same chemical features but that the atomic mass was different.
The first element found to be radio-active is uranium and it consists of two isotopes, namely uranium-238 (meaning an atomic mass of 238) and uranium-235 and the half-life of U-238 is 4 500 000 000 years and that of U-235 is 700 000 000 years. The second element found to be radioactive is thorium, which has only one form with a half-life of 13 500 000 000 years. In that same year of 1904, Bertram Borden Boltwood (1870 – 1927) discovered the fact that both uranium and thorium break down to final non-radio-active products, uranium-238 ended as lead-206, uranium-235 as lead-207 and thorium as lead-208, three of the four isotopes of lead. Boltwood also showed in 1907 that these facts could be used to calculate the age of rocks on earth by measuring how much lead of each isotope the rocks contained and today scientists agree that the age of the earth is of the order of 4 500 000 000 years.
Quite a bit older than I am!

PERCEPTIONS
The Concise Oxford Dictionary defines perception, among others, as: intuitive recognition of (something), but I would like to add: by the use of our experience and knowledge. To illustrate this definition, the following story.
Our granddaughter is pregnant with her second child and had a sonar taken some time ago in which it was evident that the second child is female, and the other day she had an appointment with the doctor for a second sonar and intended taking her firstborn, Johann, aged about a month short of 3 years along as it was a Saturday and he could not attend the play group. The following conversation took place between father Hendrik and son Johann:
Hendrik: Johann, your mother is going to see the doctor who will look at your sister to see if she is doing well.
Johann: That's good, she can then sit on my lap when we come back.
Hendrik then had to explain to Johann that the doctor used sonar to inspect his sister and that she had to remain where she was for another ten weeks or so, but all of us find Johann's reaction hilarious, because we know what a sonar does, but Johann has never seen a sonar picture and has no idea of how it is taken!
We form perceptions about things, frequently with only partial understanding of the subject, should we not try to find out more about the subject? Do we learn anything from this?

WORDS, WORDS, WORDS!
My father was trilingual, his parents were German-speaking but he grew up in the Republic of the Orange Free State and all his school mates were Afrikaans and he said that all the brothers spoke Afrikaans to each other and, as he had an affinity for langauges, later in life he was fluent in English as well. Of course he became a school teacher and eventually became principal af a school in the Southern Free State. He used to buy just about every new Afrikaans book published and could never say no an offer to buy a dictionary, I think we had about seven dictionaries in the house! He used to love a play upon words and a pun!
And the he suddenly resigned as principal of the school, took a post in a school in another town and at the end of the year he took early retirement, I have never been able to find out exactly why. He the tried his hand at farming and rented a farm near Kroonstad, but his idea of farming was to sit on the stoep with a good book and now and then giving instructions to Koki Mokeki. Needless to say, his farming was unsuccessful and he then joined the Regional Office of Water Affairs in Kroonstad.
The whole of the above is just background to what I want to write about, namely their typist in the office, an elderly lady with very little typing ability as she continually tore the paper out of the typewriter because she had made too many mistakes. One day my father said to her: "Miss Turner. I wish you would one day type a letter to the Director of Irrigation, but type Irritation by mistake." She replied: "O no, mr Grosskopf, I will lose my job if I make a mistake like that!" to which my father replied: "Miss Turner, all humans make mistakes, the man who does not make mistakes has still to be born, and then he will be stillborn!"
