Beauty of nature

Nothing is beautiful than nature. Animals, birds or flowers they don’t need any thing to enhance their beauty. They don’t need any costume designer, nor any cosmetics this is called natural beauty. Such is their beauty that they can’t be ignored. No matter, whatever your state of mind is, you are bound to appreciate the beauty provided to us by nature in form of birds, animals, insects and plants. Nature stimulated the creativity of artist and fashion industry.
I don’t have any words to say about the beauty of butterfly. But one thing I feel very sad about them is their short life span, many live just for a month.
One thing which surprises me about birds is that they don’t have hands, still are wonderful architects. Some birds are very good singers.
The best gift God has given, colours and fragrance can energize everyone.
Nature is amazing, the world which is hidden i.e, under water world is also so beautiful, wish to stay there……..
Nature has given a wonderful gift to animals, their beautiful exterior…..Fashion industry is also inspired by these creatures which we can see that they are always is trend. Its sad that these animals have to lose their life because of the beauty.

How toothpaste get stripes

Ever wondered how they get the stripes on the toothpaste? Some people even avoid buying those stripy toothpastes just so they don’t have to even think about this.
But it’s easier than it seems. And, there are not two separate compartments. The tube is filled with the carrier material, the actual toothpaste, which is usually white, to a certain level. Above that level, the tube is filled with the ‘stripe’ stuff, which is usually red, blue or green. Both materials are viscous enough so that they don’t mix. Now the trick is to let these two substances out separate ways but at the same time. The toothpaste nozzle is not just a hole at the top of the tube. Instead, it is a longish pipe that reaches down the tube just ending at the filling level of the
carrier material. The pipe has small holes in it further up closer to the nozzle. Pressing the tube will cause the carrier material to enter the outlet pipe and press the stripe stuff. The stripe material will enter the outlet pipe through the small holes, which is where the stripes are generated.
Assorted Trivia
Since the stripes only make up a fraction of the volume, the pipe protruding into the inner part of the tube must not be too long (usually about some fractions of a centimetre).
You can screw up the stripe effect by pressing the tube as close as possible from the nozzle side, forcing the stripe stuff to go through the main outlet. Or you could also knead the tube thoroughly mixing the two substances.
The patent on the method to produce stripes from the tube was bought by Lever (at date of writing: Unilever) from a New York inventor in the late 1950s.
Around 1960 the new toothpaste ‘Stripe’ was introduced into the American market. A few years later, in 1965, it was introduced as ‘Signal’ in the UK and then in Europe. ‘Stripe’ reached 8% market share in its second year and declined from then on. The stripes didn’t come out right in every third tube.
New nozzle designs to produce different shapes of stripes with different colours produced a sharp trade mark dispute in the late 1990s.
The stripes are there for the optical effect, but they may also contain different components. For example, the main carrier contains the ‘soap’, a red stripe containing ‘fluoride’, and another one might contain the mint aroma for the ‘freshness’. However, there is no strict need for the separation of these components.

Seven Wonders of Camouflage

Seven wonders of Camouflage

I am back with another wonder of nature, this is camouflage or colour changing ability of some species of invertebrates and vertebrates. This is a unique characteristic or rather a weapon which is some time used as a defense and sometime to catch prey. These creatures so perfectly blend with the surrounding that its very hard to spot them.
So, please have a look and enjoy!
1. Mollusca
a. Mimic Octopus

Camouflage by Octopus – Seven wonders of Nature

Mimic octopus: As the name suggest this is an expert to mimic other creatures. Normally it has brown and white stripes or spots. This octopus can contour its body and change its colour and also mimic the likeness and movements of more than fifteen different species including sea snakes, lionfish, flatfish, brittle stars, giant crab, sea shells, stingrays, jellyfish, sea anemones, and martis shrimps. Depending upon the predator it can decide which animal to impersonate, for example if it is attacked by a damselfish then octopus impersonate as a sea snake, (damselfish’s predator) by burying six of its arms and waving other two arms in opposite direction, and changing colour to black and yellow. Really a champion of disguise.
b. Cuttle Fish
Cuttlefishes are also known as chameleon of sea because of rapid changing ability.
2. Arthropoda
a. Golden Tortoise Beetle

Beetle camouflage

These beetles can change colour from golden to red. Instead of using pigment cells it changes its colour by altering the reflectivity of their shell, which is a remarkable feature of this tiny creature.
b. Golden rod crab spider
Depending on the flower on which it is hunting it can change its colour, but as it can change only in white and yellow so normally it hunts on white and yellow flowers like daisy and sunflower. Colour changing is induced by visual feedback.
3. Flounder fish
This is an ocean dwelling flat fish. They manage to blend so well with surroundings that it’s hard to locate them. A peculiar characteristic of this fish is that it has both the eyes on same side, which is an aid for the act of camouflage. A larval flounder has one eye on each side of the body, but as it grows one eye migrate to other side.
4. Amphibians
Peron’s tree frog can change its colour in less than an hour from grey, brown or even white. Due to its high pitched cackle it is also known as laughing tree frog.
5. Reptiles
Some Chameleons are expert in changing colour varying from pink, blue, red, orange, green, black, brown, yellow and turquoise.
6. Birds
Ptarmigan
Ptarmigan, also known as rock ptarmigan exhibits seasonal camouflage, it changes it’s colour from brown to white. In winter it’s white with black tail , and brown in spring and summer. It is a gamebird in grouse family. These birds prefer to live in barren and higher elevation areas.
7. Mammals
Some mammals like Arctic fox, Arctic hare, Ermine exhibit seasonal camouflage, with the onset of winter their colour changes to white which remain for whole winter, after winter i.e. in spring and summer they have a different colour. This change help them in both ways, catching prey as well as protecting from predators.

All Saints – Crooked Spire – Chesterfield

Crooked Spire of Chesterfield
Chesterfield - All Saints church.

All saints church at Chesterfield.

Chesterfield’s crooked spire is a parish church of St. Mary and All Saints. This famous six hundred year old crooked spire is visible from many miles around. This is a largest parish church in Derby shire, having several chapels, alabaster tomb, and a full range of historic treasure. It was built around 1350.

Since 1994, this is a member of the Association of Twisted Spires of Europe. There are altogether 72, France has 32, Germany 19, Austria 8, Belgium 7, Denmark 3, and Switzerland 2, with Chesterfield being the UK’s only representative. Chesterfield’s Crooked Spire is the most unusual, with a greater lean & twist than any other.
There are plenty of legend, about the All saints crooked spire.
Some say that a local blacksmith was asked to shoe the devil and was so nervous, he drove a nail into his foot. The devil flew off and kicked out at the spire as he passed by.
In the second tale, the devil landed on the spire and sneezed violently when the smell of incense from the midnight mass reached his nose.
And in the third, the spire turned around in amazement when a virgin was married in the church
so it leaned over to have a closer look, and if this ever happen again the spire will straighten thinking that it’s common.
The most likely explanation, though, is the lack of skilled craftsmen and the use of green timber, a lack of cross-bracing and 32 tons of lead cladding.
The octagonal spire of All Saints is timber-framed and constructed of oak, with platelets of lead-cladding rising in herringbone rows from the flat-roofed and crenellated battlements of the clock-towered belfry, up to the golden cockerel atop the weather-vane, 228 feet above the ground.
The spire currently leans 9ft 6ins to the south-west and leans more every year.
The spire also has a spiral twist of 45% from west to east at its base which is thought to be attributable to the use of green, unseasoned timber, and the weight of the lead cladding.
The spire at the All Saints was added to the existing tower around 1362, but is not attached and is only held in place by the weight (32 tons) and perfect balance.
During the 19th century an official architectural survey declared the spire unsafe and dangerous; the Town Council were ordered to either take it down, or repair it and make it safe – they repaired it.

yawning

There’s nothing like a good yawn, is there? You’ve probably heard it’s contagious, but you don’t need to see someone else yawning to trigger a sympathetic response: just reading about it can be enough. In fact, now you’ve got this far into this Entry, something deep within your neurological circuits has already rung alarm bells and is probably at this moment marshaling all the actions your body will need to take. It’s no good trying to stop it; it’s involuntary. Don’t hold back, just let nature take its course – here it comes now…
Oaaaaaaarrrrrgh
Boy, that felt good! Do you know what you just did there? Your mouth gaped open like a huge chasm and your diaphragm contracted, expanding your lungs, as you took a long, deep intake of breath. Your pharynx muscles blocked your nasal air passage, your head tilted back and your face muscles tightened – possibly grotesquely. You closed or at least narrowed your eyes, which may have produced a tear or two, as well as your mouth producing some saliva. Your eustachian tubes opened up, linking your middle ears to somewhere in the back of your nose – you may have experienced enhanced hearing for a moment. Finally, you will have made some minor changes to your breathing rate, heartbeat and brain activity. That’s not bad for something that probably only took about six seconds.
Born to Yawn
Yawning is a reminder that ancient and unconscious behavior lurks beneath the veneer of culture, rationality and language, continuing to influence our lives.
— Prof Robert R Provine, writing in American Scientist.
So when did you first yawn? It certainly wasn’t taught in school, although you undoubtedly had plenty of opportunity to practise it there. Newborn babies yawn, but in fact you first yawned around 11 weeks after you were conceived. Using ultrasound, scientists have observed foetuses not only yawn but stretch an arm when doing so1. It’s programmed into you, and into other creatures too. Cats yawn, and so do hippos, lions, whales, some birds, and even reptiles like snakes and crocodiles. It’s a behaviour common to most vertebrates, in fact, and so its true purpose is very old indeed, maybe lost in the mists of time.
Excessive yawning, however, is a recognised medical condition. It usually signals that you’re not getting enough sleep, but it could be caused by a disorder like sleep apnoea or narcolepsy, a psychological condition like depression, or possibly even a heart problem. It can also be a side effect of some antidepressant drugs. If you think you could be suffering from any such condition, then contact a medical professional for advice. If you’re embarrassed to admit that you have a yawning problem, then feel free to use the medical term oscitation. Yawning and stretching is similarly known as pandiculation.
To tell the truth, scientists are baffled by yawning. They simply can’t work out why we do it, but each ‘yawnologist‘ probably has their own pet theory. The Greek anatomist Galen of Pergamum (129 – 216AD) had one novel explanation:
Oscitatio vero est veluti pandiculatio; quam vel humor flatuosus, vel flatus vaporosus in musculis contentus gignit.
(Oscitation as well as pandiculation appear when flatulent humour or vaporous wind arises from the muscles.)
But with all due respect to Galen’s flatulent humour, scientists don’t know a lot about yawning because they haven’t studied it as much as other conditions, presumably because we don’t tend to die of it.
A Contagious Disease
For something which we do so often and so easily, we can’t yawn on demand. It’s strictly an unconscious activity. You can usually set someone else yawning fairly easily, though. Fans of the 1958 movie Tom Thumb will remember the animated sequence featuring the Yawning Man, whose infectious display sends Tom, all his toy companions and presumably many of the younger members of the audience off to the land of Nod. The phenomenon was noted by the Greek philosopher Aristotle, who described it in less-than-delicate terms:
Like a donkey urinates when he sees or hears another donkey do it, so also man yawns seeing someone else do it.
This contagion isn’t quite as ancient as yawning itself. Children don’t yawn in sympathy until they’re a few years old, and in the animal kingdom the phenomenon has been observed only in chimpanzees2.
Yawn Under a Bad Sign
Civilised society tends to take a dim view of yawning. Its association with boredom – which has been scientifically proven – only makes yawners appear ill-mannered, and we encourage children to cover their mouths during the act. Hindus once saw public yawning as a religious offence, requiring an apology by snapping one’s thumb and finger together and saying the name of the god Rama. In Islam the yawner is seen as afflicted by the Devil, who is mocking them.
Western superstitions describe the act of covering the mouth to stop the soul escaping, or to stop the Devil getting in. It was also once believed that yawning could spread the plague, and the defence was to perform the sign of the cross afterwards. On a different note, sympathetic yawning was taken as a sign that you trust the person whose yawn you have followed.
But for all of this, sometimes we just can’t help doing it. We obviously yawn when we’re bored or tired or when we’ve just woken up, but it can also affect us when we least expect it. Lions hunting down their prey are often seen to yawn just before they go in for the final kill. Similarly athletes can yawn before the big race, and even paratroopers before they jump out of a plane. Now, what’s that all about?
1 Some stroke victims even stretch their paralysed arm when they yawn.
2 Although a 2008 study suggests that pet dogs can catch yawns from humans.

Most expensive coffee. Do you know how this is prepared?

Kopi Luwak, the most expensive coffee in the world selling for between $100 and $600 USD per pound or about $50 a cup. Its also known as Civet coffee or Weasel coffee. Kopi Luwak is an Indonesian word, Kopi which means coffee, and luwak is a common name of a cat size mammal Asian Palm Civet. Kopi Luwak has an exceptional aroma and most pleasing taste.
But I’m sure many of us don’t know how this delicious coffee is obtained. Civets consumes red coffee cherries, containing fruits and seeds. But, its not able to digest the coffee beans so they are passed out. The beans and collected washed and dried. Though Civets are not able to digest the beans but their digestive juices penetrate the beans break down the proteins and enhance its flavour.
We may worry about the safety, but rigourous washing, sun drying and roasting at high temperature help to eliminate bacteria making it a safe coffee.
Really, an unusual way to get an unusual flavour…….

Alternative to exercise

We all are aware of the benefits of exercise, but still many of us don’t do it. Though I know that it’s not impossible to take few minutes from 24 hours.
