How did the hour come about as a measurement of time?

Discuss this question

Question found in Science In General
In the early days of civilization the subunits of the ‘day’ were different in different parts of the world. These were determined mostly by the position of the sun. In India till recently the day was divided into ‘nazhika’ which was divided into ‘vinazhika’. This system is still used by Indian astrologers. Similarly there were other systems. The present system of hours, minutes and seconds had been spread all over the world by the European colonizers. It is safe to assume that this system originated in Greece, the cradle of western civilization.

Comments :

Is it true that Children who live in rural (outback) Australia are educated by Radio and do not attend School as such?

What about things like Exams?

Discuss this question

Question found in Education In General
Some farmsteads in the Australian outbacks are hundreds of kilometers away from places with schools. In these areas education of the children are carried out mainly by parents or others at the farm with the help of radio, T V and the like. In such informal education systems exams may be only at the higher levels such as matriculation. This was the system sometime back. Not quite sure if this is still the case.

I've heard differing theories/opinions and could never keep the fact straight. (I've also heard some discussion that leads me to believe this may still be in question.) Are humans descendant from apes, from chimps, or from some other primate?

Discuss this question

Question found in Biology
Some people have problem with the views on creation and evolution. My view is that evolution is the continuing act of creation guided and directed by God. In other words creation did not happen in a very short time. It has taken billions of years from the first stage of the creation of the universe to the creation of man.
Let us now come to your question on the origins of man. No, humans are not evolved from apes or monkeys. We humans have animal or physical aspect (the body) as well as spiritual aspect (the soul) The body is the product of evolution. But our ancestors as far back as 7 million years were different from any of the existing primates. They have gradually changed into us. The line goes back into the one celled being billions of years back. I also believe that our soul or spirit is not the product of evolution. It was created by God ‘in His image and likeness’. This soul is what makes us so different from other animals including the chimpanzees.

Hi,

I have the following maths problem to solve. Can you help, please?

Problem

I have a series of irregularly shaped objects of different sizes (crab abdomens to be precise) and wish to compare their areas. I have been told to do this by transferring the shapes to graph paper and counting the number of whole squares within the shapes perimeter.

By doing this I will be discounting all the squares that the shapes perimeter bisects. The effect that this will have on the calculation of the overall area will be greater for the smaller shapes than it will for the larger ones. How do I compensate for this potential error and is this the best method to use?

My thoughts

I have thought that perhaps the best way to solve this would be to scale up the smaller objects so that they are proportional to the larger ones, but I'm not sure how to do this accurately and how do I convert the areas back again afterwards. Or I've thought that perhaps there is a better way of doing this and that the squares that are bisected can be included somehow.

Any help you can give would be greatly appreciated.

Regards, Helen.

Discuss this question

Question found in Science In General
Scaling up will not help. The best thing to do, in my opinion, is to count each of the whole squares as one and each of the bisected squares as half. Yet another way: count the whole squares as one each and from the bisected ones take those in which more than half is in the outline as one each. These two would help give you a good basis for comparison.

OK, here's the deal. I am a reformed, sovereigntist Christian - I believe in the complete sovereignty of God in everything. What are some compelling scriptural reasons to believe in open theism?

Discuss this question

Question found in Theology
Theism is the belief in the sovereignty of God. It is Deism where God is considered to be aloof from the creation, not concerned with the creation.
This means you are a theist.
There is no reason why you should be a deist. The scriptures point to a sovereign God.
