Wonders on Earth and the Sky!

From the sky, looking down on our Earth will be always a surprise for all of us! Winding rivers that merge with the bluish sea at their ends reflecting the images of Sun or the clouds on their surface, brownish mountains with their wavy ranges, greenish forests, cumulus clouds floating just below our level like a sea of clouds that conceal earth’s surface, dazzling large water bodies such as reservoirs, trains moving like caterpillars in the cities – all these passing slowly backwards are wonders provoking excitement in us as we watch them with awe on traveling in a Jet plane over the skies here in India!

From the Earth, looking up on the sky also brings wonder in our eyes! On 5^th December 2008, there was a wonder on the evening sky: conjunction of the crescent Moon with the bright Venus and the Jupiter planets that resembled the present day Smiley, a smiling face having these planets as eyes and the crescent moon as its mouth! On 31^st December 2008, again there was a conjunction of the crescent Moon with Venus that had moved out of the previous place of conjunction leaving the Jupiter far behind it!

As we have seen many wonders to move behind us one by one in the Golden Year, 2008, let us all see up to the sky and pray to the Almighty to make this year, 2009 also full of many such wonders!

“Wish you all a Happy and Prosperous New Year!”

Jungle Babbler - Seven sisters - nice visitors!

I find each day a flock of winged visitors in my garden at morning or evening. They give a noisy call making me to peep out to have a look at them. Often I see one of them pecking on its image in the rear view mirror of my two wheelers! These visitors are the birds called as the Jungle Babblers , and as Seven sisters in India (Turdoides striata). They have grayish brown feathers, and move the tails often either up or to one of their sides fanning out the tail feathers in the act.

These Jungle Babblers live in the tropical suburban areas only. They are seen only in flocks of seven or more, flying down to the ground or to the tree perch, one after the other following in a line. They fly lowly and do not fly away on seeing human beings; but get alerted and fly away on seeing our advancing movement towards them! As they hop around on the ground they eat insects and worms. Occasionally, they make noisy quarreling sounds with offending Mynas and chase away them!
These wonder babblers frequenting our garden are amusing and nice birds! You can share with me your experience about these birds.

Snow and Ice greet You!

At this time of winter we are reminded also about Santa Claus, Christmas tree and ……… the Snow! Snow is the solid form of water (ice!) found naturally on places having colder and the coldest weather conditions. But I have seen this snow here in our hot Subtropical region also! Yes, but ….. inside the artificial snow showering room of Entertainment Fun centers!

Some exciting factors that I came across, and wondered about this snow are here:

Snow crystals are ice crystals formed directly from water vapors by cold air, and not from the freezing raindrops! They are produced inside the clouds at -10’C. They become hexagonal prisms of ice crystals as they grow by further deposits of ice crystals on their facets. They grow branches on their six corners in the process. As they become heavy (!) enough, they move out of the clouds and float down to earth as Snowflakes! Shapes of these snowflakes vary depending upon temperature and water vapor content. Snowflakes fall down to the earth to become the Snow!

We, people in India, see only the Sand sculptures (Sand art) and wonder! But in the colder countries one can see and wonder about the Snow castles, Ice sculptures, Snowman …etc. etc. at this time of Christmas – like us too, via satellite television!

Soapnut Tree - Ritha - Cleansing hair as Shampoo!

In the past century, women here in Tamilnadu of India used to tie and wear extra entwined hair tufts on their heads. This is to show off about 'their' possession of lengthy hairs and to make up for their actual shorter hairs! I have seen such hair tufts being washed and dried before wearing on. For this a washing solution was prepared by dissolving in water the powder of dried fruits obtained from a tree. We, as children used to play with this solution to blow out bubbles of air through a tube dipped in it! The fruit mentioned here is that of the Soap-nut tree or Ritha (Sapindus trifoliatus, ‘Poonthi kuoattai maram’ in Tamil). It is a berry with a nut inside. Its fleshy part contains Saponin which has surfactant action like that of soaps and detergents! Nowadays this saponin is an ingredient in shampoos.

Another species of the soap-nut tree is found in Himalayan regions grown by Nature by itself (Sapindus mukorossi). It bears larger fruits. Seeds of soap-nut trees are said to germinate easily. But now propagation of this tree by man is drastically low; the tree needs to be grown in all farms as its canopy gives cool shadow, and its fruits have also contraceptive and antimigraine chemicals in addition to its cleansing saponin content.

This Soap-nut tree that gives us many such natural products is really a wonder tree among all the other trees, as it was in the past!

Rabies, the Fatal Disease and the Vaccines that prevent it

The disease Rabies is infective. Usually a dog having this disease spreads it to man or other animals by its bites. Rarely domestic animals such as cattle, pigs, and cats and monkeys too can also spread it. When man goes for trekking or hunting in forests he may be bitten by wild animals such as fox, wolf, mongoose and bats, that may have been already infected, and get this disease.

The virus causing this disease attacks nerves and brain after entering the body through the bite wounds. As the disease cannot be cured and leads to death quickly, one has to prevent himself from acquiring it by getting himself and also his pet animals vaccinated against it before sustaining any such bite wound. Even after any unexpected bite, the Rabies can be prevented by getting vaccinated! (- but only after immediate washing the bite wounds with soap and water, and applying Povidone-Iodine ointment - for this removes and kills the virus instantly). By taking all these precautionary measures the Rabies can be avoided by all. The wonder vaccines used get all the credits as an incurable and fatal disease is prevented by them!

Flying Termites of the Monsoon Season

In villages, here in Tamilnadu of India, people, especially children are sportive in collecting Flying Termites (Alates or Swarmers and ‘Eiesal’ in Tamil). They sing a song to threaten them, and blow air into the opening to their nest present underground! The song contains the following message: “There is snake inside the nest of these flying termites! Won’t they rush out vacating the nest?” As the flying termites come out by themselves (!), one by one, from their underground colony, they are collected in a tiny basket! One can hear these songs of the children in villages after each North East monsoon shower: at these times these creatures swarm around the places. In a few hours they shed their brown membranous wings, and then they are seen in the vicinity running one after the other in pairs. These flying termites are the reproductive forms of the Termites. They, the kings and queens from the termite colony come out of their nest, fly in air, mate with each other and settle down somewhere else inside the ground to establish their own termite colony!

Ok. What the children do with the collected flying termites? In the early part of 19^th century they simply put them on the top of the ‘Hurricane lantern,’ roasted and then relished. Elders used to roast them with fried Bengal gram (Chick pea), onion and puffed rice to make a snack for the rainy season! Now the flying termites are consumed as a side dish by the pregnant women for their high mineral contents. Their content has a good taste like that of yellowish butter and is a nutritious delicacy to all. These flying delicacies are wonderful and delicate insects indeed!

HAM and Mobile Phone Communications

In 1980s I used to tune into both foreign and native radio stations in Short Wave Bands with enthusiasm. I was able to hear the latest news broadcasts before they appear late in the daily news papers. One day while I was combing through the radio bands (SWL), I heard a radio station that was a different one from others. It had a man speaking to another man, and not to the listeners! The words repeated in the end of a conversation were: ‘roger, roger’! In response to this the other man spoke to him next. I was surprised, and understood later that they were the hobbyists, ‘HAMs’ (Amateur Radio Operators) conversing in 40 Meter band! The person’s station name (Call Sign) is VU2TX. Yes, HAMs use and speak in a lot of coded words as they also send such coded messages in Morse code (CW) – like we send now Abbreviated Text Messages in SMS! Their conversations are easy to understand if you listen to them carefully and repeatedly. You can also go through the text books prescribed for appearing for Amateur Station Operator License Examination, for referring to their coded words. (Getting through this exam entitles the candidate to get the license and speak to other HAMs all over the world!).

There are millions of HAMs throughout the world rendering services such as developing communication devices, experimenting on gadgets, helping in emergencies and disaster management through this hobby! Actually the present day’s Mobile communication devices (Phone and Signal towers) are simply the modified form of Hand held transceivers and Repeaters used by the HAMs since 1990s! HAMs’ communication networks are also the forerunners of the present day Word, Voice and Video chats of the internet, as also of the Social Community Networks such as Orkut, Myspace etc.!
We should not forget our wonder HAMs and their hobby, as they are still around us without seeking any publicity, and doing their good services. And we must be always in gratitude to them as they have provided the basis of our present day communication boom and boon worldwide!

Veins - Playing on by Emptying!

Veins are the tubes that conduct the used blood to the heart. They are superficial unlike the arteries and they can be seen prominently bulging out from below the skin in lean persons. The greenish tubes seen on the skin of the fair colored persons are actually these veins and are not the 'nerves' as many mistake them to be. They carry the blood from the distal parts of the limbs up towards the heart. They have valves in them that permit the flow of blood towards heart only but not backwards! To see this action of veins do the following:

You can place a finger tip on a distal portion in a stretch of a vein and press it down gently to block the flow of blood in it.

Then with another finger tip pressing down on it next to the previously fixed pressing finger, move over the length of the vein pushing up the blood in it (emptying) proximally.

Next take out this second pressing down finger tip. Now you shall see the previously prominent vein as an empty, dry, flat and green streak! The emptied blood does not flow back as a valve in the vein prevents it! Now if you release the pressure by the first applied finger tip, blood from the distal part of the vein will flow forwards and fill it up making it prominent once again!
It is a wonder action of the vein valves that helps to circulate the blood inside our body properly!

Shooting Stars - Meteors in Leonid Showers!

In our younger years of age, we used to gaze at the night sky and count the stars that appear, move and disappear – ‘Shooting Stars.’ While doing so, friends advised that one should immediately look at a green tree if he sees a shooting star; otherwise it might cause his death!

In 1998 November, there was news in dailies about ‘Leonid Showers.’ So, we all went to look upon the skies after midnight at about 01.30 am. The date was 18^th. You can read my jotting on my diary on that date:

“At night (1.30 am to 3.30 am) we all saw the meteors on the clear sky about one or two at a time in a gap of about 10 minutes from 2.15 am to 3.30 am”

As we waited with patience, there were these continued appearances of these shooting stars (or the Meteors) in showers. It appeared as if fireworks were lit and displayed in the sky at the Deepavali Day, here in India! An amazingly spectacular heavenly sight!

‘Meteoroids’ are the smaller separated parts from the Asteroids belt of stones that revolve around the Sun. When they come near our Earth, they are attracted and sucked into its atmosphere; but they catch fire and become visible as ‘Meteors.’ As they do so they get vaporized or fall down to the ground as ‘Meteorites.’ (It is believed that one large such of meteorites hit the Earth in Mexico and caused the extinction of Dinosaurs). But the Meteor showers of Leonid occur when our Earth passes through the dust particles left out by the comet Tempel-Tuttle.
Did these meteor showers come only in 1998? No, no! They appear each and every year around mid- November! So, you can witness this celestial event this year also in the Constellation of Leo. I wish you all have this wonderful experience! You can contact me for sharing your own rendezvous with these meteors or meteorites.
