Why do People Believe on Rumours?

Rumours multiply in the atmosphere of fear. For instance, if you are getting scared of the danger of earthquake, you will easily believe on the rumours of earthquake spread around you.

Doubt also one of the factors that force you to believe on rumours. For example, you are in abroad and you doubt your wife. In this situation, if you heard something negative about your wife, you might not think that the rumour can be untrue.

Ignorance is another cause you easily believe on rumours. For example, if somebody says you that a scientific research happening somewhere can ruin the life on the earth, then you may accept the rumour because you may not have idea and knowledge about that research.

Some rumours are promoted by coincidence. For example, you heard quarrel in your neighbourhood. You heard the sound of ambulance in the midnight. In this situation, if you don’t see your neighbour in the morning, you may think that they have been hospitalized.

Can 7 People Have Same Face in Reality?

You might have often heard that 7 different people in this world can have same face structure and body shape too. Is it really possible to have 7 same faces in actual practice? It is very difficult to draw any conclusion without deep study on the base of genetics.

Each and every kind of structure, either in face or any other body parts are due to the result of phenotype and genotype. Genotype is determined by the genetic material DNA (in human) only. However, phenotype resembled can be later on affected by different types of environmental factors. Mutation can also occur which can bewilder the normal concept we have till now about the phenotype and genotype.

What is phenotype?

The morphological (physical) structure seen as an outer appearance due to the effect of genotype as well as influence of environmental factors is known as phenotype of an organism. Mutation directly affects the genotype acquired from heredity (process of transmission of physical and genetic characteristics from parents to offspring). Genotype affects phenotype.

What is genotype?

The genetic makeup or the genetic structure of an organism generally acquired from heredity, which is stored in DNA of an organism, correspondingly resembling the phenotype is known as genotype. It is the gene where mutation takes place.

Taking into the consideration of the time right when human species started to till now, evolution played vital role to change us drastically. Although from generation to generation we have evolved but we are all diversified forms of our single ancestor. The genes contained in our ancestor got mutated in different ways during cross fertilization due to which hybrid species were formed which were genetically different. During the hybridization of the species the genotype of the species go through the changes that make changes in phenotype. The genetic change makes physical change in us. The face, body structure, characters required for adaptation, etc. get modified in every filial generation during cross breeding.

The question may be raised that how was it possible to form species of different genotype to form non-sister species (species from different parents having same genotype) when there were only one maternal and one paternal form of the very species, say human. As mentioned above, the mutation plays vital role in abrupt evolution. The geographical aspects, mode of nutrition and different environmental factors bring about a change in the genetic structure of the species. Furthermore, different rays of the sun also alter the coding of DNA. It changes the genetic structure. In this way, species of different genotypes are formed.

When non-sister gametes are fertilized, new hybrid form of the species is formed which is different in both genotype and phenotype.  This phenomenon continues for several thousands of years to form large diversified groups of same species, which are distributed all over the world. This is the reason we are having people all over the world having different faces and body structures. Everyone differs from each other in at least one or two genetic or physical characters. Nevertheless, we hear that two people having same face were reported. Now after getting the background of what brings about a change in the genetic and physical structure of any species, let us go deeper to find out whether it is possible to have same face by two people or not.

*In this diagram, BB, Bb and bb represent pure black eyed, hybrid black eyed and pure blue eyed respectively.

According to Mendel, the dominant character is always seen in first filial generation which suppresses the recessive character but they do not mix with each other and recessive character can be seen in next generation as it is just hidden but not vanished. The occurrence of one contrasting character doesn’t affect the occurrence of another contrasting character. Although there are many contrasting characters to be considered which determine the genotype and phenotype of one single species, there is great possibility of having at least 90% of common contrasting characteristics after many filial generations. According to the law of Mendel, the contrasting characteristics if do not appear in one filial generation, it can appear in next filial generation. Similarly, changes seen in one generation of human can again come back as previous one. Let us consider a generation in which offspring have black eyes. In next generation offspring can have blue eyes as hybrid product. Let this line of generation continue up to where it can. Let we assume that current generation has blue eyes. Let us suppose another line of generation which had blue eyes before and after hybridization they have blue eyes again after passing through many filial generations. At the end, product of both impure lines will have common contrasting character i.e. blue eyes anyhow. In this similar process, if we consider the changes in all the contrasting characteristics like height, color of hair, presence of dimple in cheeks, shape of ears, etc. If there is similar genotype seen in two different people then the physical appearance is similar. After many filial generations, it is possible that people can have almost same genotype with each other. It is the reason we find different people with same face. They almost seem to be clones.

So, if people have same or similar genotype then they will surely have similar phenotype. They can have exact same face and body structure. Not only as rumor but for sure it is possible that 7 people can have same face. Not only 7, thousands of people can have similar face if they have similar genotype. It is true that after many generations and evolution we go through, we again get back to our ancestor’s characters which were being hidden as recessive characters due to presence of dominant characters. Don’t worry thinking that we will completely turn out to ancestors as many of those rare contrasting characters have already got vanished with them but still some characteristics may appear sooner or later if they are hidden. So, when you meet someone of similar face with yours, feel lucky that you got someone of similar genotype of yours and you have some kind of fade connection with that person. That person might be from the same ancestor of yours.

7 Cool Facts about Inventions and Discoveries

Today I am sharing my views about some facts about inventions and discoveries. I have noticed 7 very cool facts about inventions and discoveries during my research on various topics.

1. There are many ways to invent the same thing.
Inventions have different versions. Just think in how many ways electricity can be generated today. Just remember how many different ways scientists are talking to invent time travel. These things prove that inventions can be done differently.

2. Invention happens in right time, not before the time.
Invention does not happen before the time. That’s why humans might have got only 100 years age. It’s because if humans have much time, they can invent much more things before the time. It would disturb the balance in the universe maintained by nature.

3. Invention happens when scientists see anything around with new prospective
Most of the inventions are just a common sense. Inventors see same thing differently than any common man. Law of Gravitation, General Theory of Relativity, Special Theory of Relativity, etc are the results of the different views on the same thing visible to everyone.

4. Inventors are the greatest people on the earth.
All people have equal role in this world. However I think inventors and discoverers are the greatest. Just think what would have happened if Thomus Elba Edision had not invented electric bulb; Rights brothers had not invented aeroplane and Charles Babbage had not invented Computer? We cannot imagine a prosperous civilization without inventors and discoverers in this world. So inventors and discoverers are really greatest people on the earth.

5. Invention can be done in two ways, theoretically and practically.
Everything in our universe is mathematical. So invention can be done either theoretically {mathematically} or practically. The thing {higgs boson or god particle} which Peter Higgs had discovered by his mathematical calculation years ago was practically proven in 2013 A.D. The equation which Einstein developed was related to the atom bomb. So there are two types of scientists, i.e., theoretical and practical scientists.

6. There is oddity not impossibility in Science
Nothing is impossible in Science. Yesterday, television, computer, electricity, atom bomb, telephone, etc were impossible. Tomorrow time travel, invisibility, immortality, etc will be possible.

7. All inventions are discoveries.
The universe is full of secrets. There are uncountable mysteries. Invention is the search of those mysteries. So, all inventions are discoveries.

Is It Possible to Build an Earthquake Predicting Machine?

People believe natural calamities are unpredictable. But there are always some people in another side who believe that nothing is impossible. What do they say about the possibility of an earthquake predicting machine?  They obviously say YES IT IS POSSIBLE.

There are many reasons we can believe that the world will have an earthquake predicting machine one day. Have a look at some strong reasons:

1. Nothing is impossible
I have already mentioned above that nothing is impossible in this world. Yesterday flying in an aeroplane was impossible. But today it is possible. Similarly, people of today think earthquake predicting machine is impossible. But it will definitely be simple thing in future.

2. Long term prediction is acceptable
All most all earthquake scientists including USGS researchers believe that long term prediction is possible and they are doing it correctly in most of the situations. So if long term prediction is possible, why is not short term prediction possible? And that short term prediction is the key to the earthquake predicting machine.

3. Aftershocks are predictable
Even the people who do not believe on the prediction of earthquake believe on the prediction of aftershocks. USGS also forecasts aftershocks. So it gives a hope that if aftershocks are predictable, we cannot reject the fact that mainshock {earthquake} also may be predictable.

4. Foreshocks are predictable
Foreshocks are the smaller earthquakes that appear before the mainshock. There are some examples where mainshock has been predicted with the foreshocks. So it gives a chance of earthquake predicting machine.

5. Earthquake takes place according to the laws of science
Everything which runs according to the laws of science is predictable. And it is simple to believe that earthquake is not beyond the laws of science.

The common point people often say earthquake prediction is not possible is that every earthquake is a different event. But this is oddity not impossibility. It says that one single machine to predict all different types of earthquakes is not possible. But there is a chance in another hand that earthquake machine can be made differently according to the types of earthquake. It means separate earthquake machines can be built to predict earthquakes of particular areas with particular features.

What Happened to the Aftershocks of Nepal?

I agree with you if you think that the defined title of this blog seems to be very cool. Really, what happened to the aftershocks of Nepal? The question itself answers that Nepal has not experiencing aftershocks for a long time.

The concern of earthquake has recently overshadowed in Nepal due to the ongoing political hot issues, i.e., promulgation of constitution through constituent assembly, movement in terai, undeclared blockade by neighbouring country and formation of the new government.  However, aftershocks have tried to drag the attention of people time to time. See the screenshot below:

The record shown on the screenshot above says that the aftershocks are still going on but they have decreased exponentially from the month of September. According to this data the general gap between two aftershocks is around one week. This gap is in the process of increasing ahead. In the coming months aftershocks are expected to appear only after a long gap and also in a few numbers. However, it is estimated that aftershocks take more months to stop completely. Because last two aftershocks were 4.6 and 4.5 magnitudes which are still big in size.

White Tiger in Nepal

An initiative research has shown that the white tiger, one of the extinct species of the world might have existed in the forest of terai region of Nepal. The extinct animal may be scientifically documented if the research is done by fixing the CCTV cameras in the forest of Nepal.

The modern history of Nepal theoretically records that Jung Bahadur Rana, the first prime minister of Ranarchy had seen the white tiger while his hunting time in Rautahat district of Nepal. But the then uneducated society had taken this incidence as the effect of ageing on Jung Bahadur Rana.

One of the most famous novels titled ‘Seto Bagh’ notably represents the incidence of Jung Bahadur’s sight on white tiger. The title of the novel has been defined after this animal. The novel was written by Diamond Shumsher who was an established writer of Nepal.

Mr. Diamond Shumsher is known for his creation in historical stories. He especially tells the story of Rana family. He himself was from Rana family. And it is said that he was disliked in his family for writing about them. Recently the ‘Seto Bagh’ novel has been filmed in Kollywood which has got huge audience in theatres.

White tiger is still taken as a hoax in Nepal. Few people know white tiger is not a character of illusion and stories only. The white tiger actually exists on the earth. Particularly they are from India. May be they are found in Nepal too. Jung Bahadur’s encounter of white tiger is a hint.
