In the year 1905 A.D, Einstein published his work that later came to be known as the “theory of special relativity”. The paper consisted of ideas that were far ahead of its time. The theory was revolutionary but also was so unconventional that it shook peoples intuition about space and time. The former concept of time being universal to all the being on and off earth was changed by him. His theory postulates that the speed of light will be same irrespective of the state of motion of its source.
His theory brought about the concept of time dilation. Time dilation simply means, that time runs slower when you travel at speed comparable to the speed of light i.e “c”. Now this may seem to be uncommon or had to visualize but its a proven phenomenon and that is how he discovered the ways for time travel. From his theory the following can be used for future time travel:
It might come as a shock but the people in the international space station that is always rotating earth at a high speed are actually time travelers. Their constant state of motion in comparatively high speed bring about the minuscule level of time dilation. This dilation causes them to age slower than the rest of people on earth. In other words, if we are able to travel at a speed of 90% of light’s speed we will age 2.6 times slower than people on earth. Travel now at that speed and leave earth, if we come back after 4 years the earth will have already advanced by 10 years. That means we literally jumped 6 years of earth time. Though our friends on the ISS don’t experience such big time jump, but they do gain some very very small amount of extra time.
The particles that runs through particle accelerators like LHC, are very lucky. They travel at a speed of 99.99% of speed of light and for them 1 sec is equal to 11 months on earth normal time. This is the result of time dilation and thus Einstein discovered or more like theorized it.
The other method also came from Einstein. This time general relativity. In general relativity he introduced the concept of how the universe experiences the space and time as wide spread cloth that can bend when an object is placed over it. For simplicity imagine a stretch trampoline with a heavy ball in the middle. Those curves around the ball is the bend in space and time. Now if the ball is big enough to bring about a major bend in space and time, he says it can slower the time. Precise atomic clocks at different gravity level have been used to test for this phenomenon and turns out, it is true. When an object is subjected to heavy gravitational force it experiences a slower time. Practically, we would need a very heavy object like a black hole or other such scale heavenly bodies to see a significant time jump for us. Though it seems not feasible for humans any time soon, the clocks on the satellites seem to experience it all the time. Those clocks and the clocks on earth are required to be constantly synchronised taking in account for the gravity to keep them functioning.
The GPS satellites are constructed taking in account for both the time dilation and gravitational effects. If any one of them is left out, your GPS won’t be working as precisely as it should be.
As explained in the movie “Interstellar”, wormholes are holes in spacetime connecting two different points of space and time. These “holes” in spacetime are also the solution to the equation published by Einstein in his theory of general relativity. Theoretically, anything that goes through wormholes can jump between two points of space and time. It is believed that many wormholes are being constantly created and destroyed in the quantum level but finding a wormhole that can fit a person or a spaceship is a challenge yet to be completed.
Apparently, time travel isn’t really an unattained dream at this point. The only compromise is it is not significantly large and we can’t seems to control at which point we exactly want to go. If you are still thinking about traveling back in time then it is discussed in this post. What you think about time travel? let us know in the comment.
What’s Special Today: November 10
Historically native to the Indian states of Bihar, eastern Uttar Pradesh and Jharkhand and the southern part of Nepal, Chhath is one of those festivals that transcends the caste system that exists in the society. According to the Hindu calendar, it is celebrated on the sixth day of the lunar month of Kartik. The Chhath Puja is a 4-day long ritual specially offered to the solar deity, Surya, to show thankfulness for good health, good life and to request the granting of some certain wishes.
Day 1: On the first day, the devotees after bathing clean their house and eat the food that is offered to the god to protect the mind from the vengeful tendency.
Day 2: On the second day, the devotees are not allowed to drink even a single drop of water but, in the evening, they eat kheer made up of jaggery, fruits.
Day 3: The evening of the third day which is also known as sandhya ‘arghya’ day where a bamboo basket is decorated with various puja materials, fruits, thekuwa, and laddus which are offered as an ‘argya’ to the Sun. Also, the Chhathi Maiya is worshipped.
Day 4: On the last day of Chhath puja again an arghya is offered to the Sun God but this time in the morning. The devotees go to the riverbank to offer arghya to the rising sun and break their fast and conclude their four-day long worship.
Happy Chhath to everyone! Don’t forget to enjoy some thekuwas!!
World Keratoconus Day:
Every year on November 10, World Keratoconus Day is celebrated to focus global attention on keratoconus and ectatic corneal disorders. The day was first celebrated by National Keratoconus Foundation.
Keratoconus is a disease that causes the cornea to become weak, leading to the thinning and stretching of the cornea, which may result in the loss of vision. Keratoconus is degeneration of the structure of the cornea. The shape of the cornea slowly changes from the normal round shape to a cone shape which affects the vision. The keratoconus mainly develops in teenagers and young adults and the disease keeps on growing, if not diagnosed in time.
The disease has no prevention and no treatment. With early diagnosis, the disease can be managed and further damage can be protected. In Nepal, the prevalence of Keratoconus is 1 in 2000 according to the recent journal. So, this world keratoconus day, make a commitment to visit an eye doctor once a year for the early diagnosis of keratoconus as well as other eye diseases.
Best and Worst Bank in Nepal as per our survey
We had conducted an online survey to find out how banking services in Nepal are being used and perceived by their users. This article is entirely based on those responses. Thank you Muktinath Bikash Bank for supporting us in conducting this survey.
Over the years, Banks have become an integral part of our daily life and economy. With the shift to digitalization and modernization of the economy, banks have definitely made life easier for people to manage their cash and transactions. With these shifts and increasing dependency on banks more than ever, the use of banking services and users’ banking experience is one of the topics with the minimal amount of research done. Out of curiosity, we conducted an online survey to find out how people have been feeling about the banking services provided by the respective banks.
Respondents were mostly urban educated youth with access to the internet, in the age bracket of 18-40, mostly being from 22-26 age group. The data was collected through social media users, primarily from page followers of KMAG. In total, we got 219 responses out of which 160 were males and 59 were females.
In the list of questionnaires, one of the questions was “which is your favorite bank from Nepal as per your own experience,” and another being “which bank do you think is the worst.” Among 219, 27 respondents were undecided and 192 casted their votes for “best” and the “worst.” To build the conclusion on more strong foundation, we wanted to make sure respondents voice their opinion per their experience for which we had also asked them to reveal their primary bank.
Out of the total participants, a majority of 89.6% have multiple bank accounts though 19.5% of them just use one of those accounts. The remaining 10.4% claimed to have an only bank account. Out of all those banks, Nabil Bank is the primary bank for 36 participants (which was the highest no. of primary account holders in a particular bank). After Nabil, most of them were primary users of NIC Asia, Global IME, and Siddhartha Bank.
Nabil is voted as “Favorite Bank”
Nabil Bank seems to be the most favorite and popular among the respondents. With a total of 45 votes, it was voted the “most liked” bank. Among them, 29 were the primary account holders of the bank. Under “least liked,” it only got 4 votes.
To briefly talk about Nabil Bank, Nabil Bank is an ‘A’ class commercial bank which was founded in 1984 A.D. (2041 B.S.). It was established as Nepal’s first private sector bank incepted by multinational investors with the objective of providing modern, international-standard financial services. It was first established as Nepal Arab Bank Limited. In 1995, Dubai-government owned the majority of shares was bought by Binod Chaudhary.
NIC Asia is “least favourite”
With 76 votes for “worst bank,” NIC Asia seems like the “least liked” bank from Nepal as per the responses. Interestingly though, it has also been voted as “favorite bank” by 17 respondents.
After NIC Asia, Nepal Investment Bank seems like the second “least favorite” bank from Nepal with 23 votes against the bank.
On being asked the reason for disliking the bank, most of the participants seem to agree on the same point and that is “terrible” customer service of the bank. Similarly, other reasons were bad internet/mobile banking facilities, fraud-like business practices, and lack of important banking services/products being provided by the. Not to forget few were unhappy about the lack of branch/ATM services.
The detailed data are presented in the table below:
|Global IME Bank||25||17||10|
|NIC Asia Bank||29||17||76|
|Standard Chartered Bank||9||8||2|
|Bank of Kathmandu||5||6||1|

|Kamana Sewa Bikas Bank||1||3||1|
|Prabhu Bank Limited||8||3||8|
|Rastriya Banijya Bank||3||3||9|
|Agriculture Development Bank||2||2||2|
|Nepal Bangladesh Bank||2||2||2|
|Nepal Investment Bank||15||2||23|
|Garima Bikash Bank||2||1||0|
|Nepal SBI Bank||2||1||11|
|Prime Commercial Bank||7||1||2|
|Manakamana Development Bank||0||0||1|
|Shangri-la Development Bank||1||0||0|
How to design a survey questionnaire
This article was originally designed for KMAG Online Writing Workshop and made available to public for knowledge-sharing purpose.
A survey is a list of questions aimed at extracting specific data from a particular group of people so that the surveyor can gain knowledge and insights into various topics of interest and then mostly generalize the result. How to design a survey questionnaire completely depends upon the purpose behind the survey. Depending on the purpose, questions are framed.
Let’s understand this way, surveyor seeks to know anything based on either of the following grounds:
- They don’t know anything, they are curious to find out, and they seek for answers. Example: I don’t know many people smoke and I want to find out by asking everyone out there.
- They think they know but they are not sure and they want to find out if what they think they know is actually true or false. Example: I think 50% of Nepalese do smoke but I am not sure yet and I want to validate my assumption by surveying.
- They strongly believe that what they know is the facts and now they want to interpret the world based on the “facts” they live by. Example: I strongly believe that smoking is bad and raising tax and making it expensive is the way to discourage people to smoke. I want to survey to find out how many Nepalese believe the same and agree with raising taxes and making it expensive would discouarge people to smoke.
Whatever grounds you are holding, you must frame your questionnaire according to that. So before working on the questionnaire ask yourself if you are trying to know the unknown or are you trying to validate or crosscheck what you think you know or you are trying to pass judgment or views based on your preset theory/hypothesis that your understanding is based upon.
This is how it goes:
You already have a theory and you want to analyze people based on the theory.
Let’s take for example “Job satisfaction Survey.” In this case, as per your theory/hypothesis, to be called “satisfied” one must be displaying so and so traits and views; if not, the person is not satisfied in his/her job. Based on that, you will be designing a questionnaire and see how many people meet the criteria to pass your judgment. If your theory says, highly satisfied people have flexible working hours, one of your questions will be something like “Can you come to your office at whatever time you want and can leave per your own wish as long as you are doing what you are paid for? Yes/No/Depends.” Likewise, there will be other questions set in a fashion to funnel your judgment regarding what percentage of people are satisfied with their job and work.
You have a theory or hypothesis that you want to validate or crosscheck
In this case, you have an assumption but you are not sure of and you want to crosscheck or validate by testing it on people. For example let’s say you think “Most arranged marriage people are unhappy,” and you want to validate your claim or crosscheck the truth in it by surveying among arranged marriage couples. Your questions will be something like “If you have to rate your marriage in terms of joy and happiness in it, how much will you rate on a 1 to 10 scale?” followed by questions like “if you have a time machine, would you go back right before the marriage and take your time to find out someone to have a love marriage? Yes/No/Maybe”
You don’t have any theory or hypothesis and you are only to find out unseen/unknown reality
In this case, you don’t have any preconceived thoughts or assumptions and you are plainly trying to learn or find out in an open-minded fashion. Like for example, You don’t know how many educated youth from Nepal actually do smoke, nor you know why they smoke despite its negative effect and you are set out to find out the answer by surveying. In such surveys, your questions will be like “do you smoke? Yes/No. “If you smoke, how many cigarettes do you smoke per day?” “despite its negative effect, why do you still smoke?”etc.
Sometimes, you can have a mixed approach, wherein the topic of your interest that you are surveying on, part of it is something you strongly believe being fact, part of it is something you are unsure about, and part of it is something you don’t know a thing about and you are willing to learn. Like for example, you strongly believe happy couples display so and so traits, and you think couples from love marriages are happier but you are not sure of, and you don’t know at all if personal happiness is valued more in marriage or responsibilities and social factors in the context of Nepal. So part of your questionnaires will be driven by your theory that you consider as being fact, part of it will be intended to cross-verify your assumption, and part of it will be purely seeking truth as it is without any deliberate attempt to frame your assumption.
Bottom line, you should know your ground, the purpose of surveying, what you intend to do afterward, based on which you should be working on your questionnaires. Your questionnaires will be designed according to your intention, so there is no hard and fast rule but make sure, in the end, you gather all the relevant information so put together to build a conclusion and for that, you need to think about what all needs to be asked to fill up the blocks and connect the dots.
