Why is water transparent?

Discuss this question

Question found in Physics
Every substance in this world has properties that some significance to life, to comfortable living. Glass is transparent and so we can use it for windows to see through or for spectacles. Wood and stone are opaque so we can use them for walls of our rooms to provide privacy.
Water has many properties that are unique and essential for life. The fact that it has maximum density at 4 degree Celsius and that ice floats on water prevents the oceans from freezing over totally destroying all life.
Transparency of water is essential for the subsistence of the higher aquatic forms of life, for vision, to see through. This vision is necessary for finding food as well as for defence or protection from predators. Everything has a meaning.

Comments :
Having selected the category "physics" for this question rather than "religion", or indeed "just so stories", I had hoped for something a bit more reasoned and physically based rather than a teleological and Micawberesque appeal to the rightness of all things.

Why do we have to sleep?

Discuss this question

Question found in Biology
All our body systems need rest and relaxation for efficient functioning. All our systems are controlled by the brain and the brain can work efficiently only if it gets regular rest. We know what happens if we tax our brain for continuing activity for more than 24 hours.

What does Quantum Physics tell us about time?

Discuss this question

Question found in Physics
Quantum physics and the theory of General relativity are at the two extremes of physics, the microscopic (nanoscopic?) and the macroscopic. Relativity puts time as one of the dimensions of our universe, the space-time continuum. Physics says that time is relative - it has no existence by itself, independent of space and matter. The main thing to remember is that physics - at all levels - cannot define time. All that quantum physics says about time is that the smallest measurable time -Planck Time - is 10 to the power of 45 seconds.

Are dimples formed on cheeks a symptom of ill health?

Discuss this question

Question found in Health & Fitness In General
Dimples are not sign of bad health. But I think you mean pimples, right? the pimples are supposed to be due to deficiency of vitamins esp vit A. I know one Ayurvdic powder that is very effective in removing these and giving clear skin. Some teens consider pimples add to their beauty and do not want them removed. Anyway they are nothing to worry about.

What is the difference between Regeneration and Conversion?

Discuss this question

Question found in Theology
Words have different connotations in different contexts. Even in the field of religion the word conversion has different meaning to different people. In common parlance it is understood to mean change from one religion to another. Literally the word ‘convert’ means to change direction. If invert is in the vertical plane, convert is in the horizontal plane. In religious context, conversion should mean a change in one’s life – a spiritual progress. Within the same religion conversion makes an individual a better person. This is the same as regeneration, which is spiritual renewal or improvement by removing one’s defects. So it would appear that conversion and regeneration are both the same. But there is a slight difference. At whatever level you take the word conversion, it involves a change in direction, may be from materialistic to spiritual. But regeneration implies improvements in the original direction without change of direction.

Is it true that due to falling attendance levels, Churches are no longer built in Great Britain?

When and where was the most recent Church built?

Discuss this question

Question found in Religion & Spirituality In General
It is a fact that church attendance levels as well as vocation to priesthood are going down not only in Great Britain but most of western Europe, north America as well as Australia. At the same time there seems to be a positive trend, a more active participation, in Asia and Africa as well as South America.
If in the past missionaries from the western world preached the word of God in Asia and Africa, today we see the missionaries from Asia and Africa preaching the Word in the western world.
If you take a survey of attendance at Sunday mass in Australia you will note that other than the Asian immigrants it mostly consists of senior citizens. I am told that this is the case elsewhere as well.

I wouldn't know about new churches being built in Britain, but I know that in Australia churches in cities are being sold to bolster the finances of the congregation. In 2003 one of the protestant denomination put up a church for sale in Sydney. One eastern church group that was looking for a place of its own to worship gave an offer of one million dollars. But the church was sold to a real estate developer because he offered 1.2 million. In downtown Sydney there is a restaurant with a peculiar architecture. Once that was a church.

What is a mean reading as opposed to an average reading?

Discuss this question

Question found in Education In General
In statistics there are three different forms of 'average'. they are, mean, mode and median. This means that 'mean reading' is one of the 'averages'.
The mean is also called the arithmetic mean and is obtained by adding up the values and dividing the sum by the number of values. Thus the mean of 4, 5, 6, 7, 8 is 30/5 = 6 . This is also what is known as the average.

"It is possible to generate stem cells without destroying the embryo and without destroying its potential for life," said Dr. Robert Lanza, chief scientist at Advanced Cell Technology in Massachusetts.

Last month Pres. Bush set the record for longest time in office without using a Veto. He broke the record by Vetoing a stem cell research program law.

Having said these two things. How does the Radical Religious Right Wing feel about beginning stem cell research?

Discuss this question

Question found in Religion & Spirituality In General
I do not belong to the group mentioned and so I am not sure if I am qualified to answer your query. But to the best of my knowledge the 'radical right wing' is still very much against all forms of stem cell research.
Despite the statement of Dr Lanza, stem cell research involves the production and exploitation of the embryo for purposes other than that for which it is created, to be nurtured and nursed with love and care.

How would a mother like its new born baby to be taken to the lab in place of a mouse to do research work on finding the reactions of some new drugs for infants being developed? The 'human' element is forgotten here. Though I do not belong to the 'radical right', though I am not an ardent supporter of George W Bush, I am strongly against the idea of stem cell research.
