How and What

  Evolve to be better Most living organisms on earth are either too bigger in size or are too much hardworking or may live too longer lives against humans. Some of them have got so advanced senses that sometimes our machines fail to attain that much of capability. Some can run or fly or swim even faster than most of our average cars. We as humans are actually fragile with body and most organisms, weather aquatic or terrestrial animals, micro bacteria or macro insects, reptiles or mammals or amphibians, carnivorous or herbivorous; all can easily kill an average human being without much effort. Still humans are called the most dangerous animals on earth. The reason is that though we don’t have much muscle power and we don’t have the sharp teeth and nails to kill, but we have got the intelligence, memory, precision and control. We as humans do a lot of things and have a lot of things to worry about. We always have a pressure to compete with others and attain better positions i...

Aurora Aurora, which is one of the Seven Natural Wonders , is a beautiful display of green, blue and red lights in the higher latitudes near Poles . These occur when atoms present in the magnetosphere are excited and ionized because of solar wind. These excited particles are then transported towards the poles due to the effect of magnetic pull. When these particles collide with the atoms present in the atmosphere, electromagnetic waves of different bands are produced depending on the energy of the charged atoms. An aurora is mainly of two types, first one of which is diffuse Aurora. This one is mostly not visible to the naked eyes even in a dark night. It is extended all over the aurora zone and depicts the extent of aurora zone. The second one is the discrete aurora. It occurs within the diffuse zone and it is visible to naked eyes. Sometimes it is so bright that a person can even read on a dark night. Though, the auroras occur round the year, but, they are only visible d...

Global warming Increasing global warming may not be a serious matter for most, but it has the vast potential to change the face of the earth completely, forever. The slogan ‘Save Earth’ or ‘Save Nature’ are very common these days but these doesn’t arise a sense of responsibility among most people as they simply walkout of the conversation by just saying “This is not my fight, I got a lot of other things to worry about”. Now I would like to remind you that earth was formed billions of years ago and since its formation, it has faced an unknown number of disasters and mass extinctions, but nothing really happened to it. Every time when something bad happened, some species that didn’t fit were wiped out, nature again played its role and new species were evolved. Now it may be a reason to think that this time it may be our species. So you should try to ‘Save Yourself’. A small increase in few degree of temperature may not offend us in personal, but if this increase is as alarming as...

Celebrity trees Widest Canopy – The Great Banyan This single clonal tree covers an area of 14500 square meters and has a circumference of about half Kilometer. The Great Banyan is a 250 year old Banyan tree located in Calcutta, West Bengal, India. This tree was struck two times by lightning because of which, the tree has been left without its main trunk, but due to about 3300 areal roots reaching ground, the tree is still standing and is spreading its branches continuously. Due to these roots, the tree looks more like a forest than an individual tree which it actually is. Largest volume – General Sherman Though it is neither the tallest, nor the broadest stemmed tree in the world, still it is known to be the largest living individual on earth due to its enormous volume of the trunk. It is a member of Giant Sequoia in California State. Though it is the largest tree by volume, currently, but it has not been the largest always since Crannell Creek Giant, a member...

Saiga Antelope The significant feature of this species of antelope is its strange and  over-sized  flexible nose structure. Earlier it was wrongly considered that it drinks with its nose. It measures about 2ft to 2ft 7 inch from toe to shoulder and males are slightly larger than females. Male antelope has two well-developed helical thorns which are completely absent in females. As per current status, it is Critically Endangered and only 50000 Saigas are alive today, but this decline in their number has occurred in the recent years only. When it was found in abundance, its hunting was encouraged by WWF under the Rhinoceros prevention program, since its thorns were considered as an alternative for preparing Chinese medicines. Originally it inhibited a wide area of Eurasian steppe and also lived in North America at the time of Ice age. Saiga Antelope avoid steep or rugged areas but gaze in huge herds in vast semi desert steppes and migrate over long distan...

Narwhal A narwhal also known as narwhale is found around the arctic continent. It has a long straight helical tusk which exceeds the length of whole body with age. The tusk keeps growing for the whole life and may reach up to 5.5 meters. This special feature of narwhal is actually an elongated upper left canine in males. Generally females don’t grow tusks but a very small number of females too have elongated tusks which are generally smaller than those constituted by males. Most of the males have only one tusk but there are exceptions too. One in 500 narwhals is reported to have two tusks which is the result of elongation of the upper right tusk. The right tusk is always smaller and less straight then the left one. The average length of a male narwhal is about 4.1 meters which is larger than an average female (3.5 meters). Males attain puberty at about 11 to 13 years of age and females reach sexual maturity at about 5 to 8 years of age. The helical tusk of narwhal is holl...

Atretochoana eiselti (Penis Snake) It is a very strange species of Caecilian. There is very small amount of data available about this species but everything that has been discovered about it is strange. It doesn’t have nose and is lung less creature, thus its breathing mechanism is an unsolved mystery. It has an enlarged mouth with teeth and has a snake like body. The body texture looks like a loath of flesh. Due to these features, it looks exactly like a gigantic human penis (this is the reason for its second name). Until 2011, when it was rediscovered in Brazil, the only information available about it was gathered by studying the specimen placed in the Naturhistorisches museum in Vienna. Being so concealed, it has been declared as data deficient and there is no information about its food, lifespan or whether it is aquatic or terrestrial. Credits: Image Source- Google Images

Irrawaddy Dolphin Most of us must have seen or heard about the intelligent dolphins that are famous in the aquariums worldwide. They are very friendly and have very sharp memory too. The even help fishermen in Southeast Asian costs in fishing as they can be trained to catch small fishes in fishing nets. For doing this they are tied to fishing net and then they dive inside the ocean to trap fishes and then are called back to the coast by using a specific ultrasonic frequency. Due to these capabilities these oceanic dolphins have secured an important place in the traditional fishing techniques. Due to this, sometimes they are drowned with the fishing nets or are killed unknowingly. They are also captured for keeping in ponds and aquariums. These activities have threatened their species to a large extent. Irrawaddy dolphin has been declared as vulnerable and the species is critically endangered in many countries like Laos, Malaysia, Burma, Thailand and Philippines. Habitat degradation...

CATIA Teacher Knowing about powerful 3D modeling tools is must if you are pursuing an engineering course. If your college does't provide the free training then too there are various coaching centers around, which teach CAD/CAM tools. Though they are good but many of us find it difficult to afford. That's why I decided to write a helping article which would introduce you to the basics of the Part Design Workbench of CATIA. CATIA contains lot many tools too other than just mechanical design, but I would restrain my topic to the Part Design Workbench only. Knowing the method of modeling  a 3D part and assembling it to the other parts in the Assembly Design Workbench is an enough introduction to start with CATIA. Once you master this much, you may step forward on your own to other workbenches, since they are similar. Though, newer versions of CATIA are already available, I would take all the references from CATIA V5 R17.  There are always two or more ways to do an action but...

Pink Fairy Armadillo A pink fairy armadillo is a mammal and is found in the dry grasslands and sandy plains having thorny bushes in the central Argentina in the continent Africa. It has astonishing digging capabilities and can disappear in the land within seconds when scared. It lives near ant nests by digging holes in the land and feeds mainly on ants and their larva. It is also seen eating snails, small plants, etc. It is the smallest creature in the armadillo family and is has a strange bony armor shell to protect itself. When measured without the tail, its length comes to be around 10 cm (9- 1.5 cm ). The pink has been added to its name because of its pink or pale rose color. It is basically a sand swimmer and spends most of its life underground. It has large front claws which is very useful in moving forward under the sand in the same way as water. This category of armadillo faces great threat due to increased cattle farming and was declared as endangered by IUCN in 19...

The Japanese spider crab It is an orange colored crab which has the longest leg span among any arthropod. The length of the legs from toe to toe may reach up to 3.8 meters and its body may grow up to 40 cm. the total weight of the whole adult crab is about 19 kg. It is a species of marine crab that live in the water bodies and costs of japan. They face a little bit of fishery, which led to the decline in their number and was preserved to its present status. They are mostly found in the southern cost of japan and adults may be easily found at the depths of 600 meters. They like to live in the holes or vents in the bed of the ocean. The larva of Japanese spider crab is carried by the female for around 70 days and when born, larva is in transparent state. The Japanese spider crab feeds both on aquatic plants and animals. Due to their long and strong legs they are dangerous and look strange in appearance too. In many parts of japan, it is also considered as delight on the dini...
