Factual Questions 

1.What is a  sequences?

A sequence is a list of numbers arranged according to a rule and is separated by commas is known as sequences.

For example; 1,2,3,4,5,

2. What is a series ?

The sum of terms of a sequence is series.

For example; 1+2+3+4……

There are different types of  series ; Arithmetic series, geometric series, convergent series and divergent series.

Arithmetic Series : A types of series which involves addition or subtraction of  a sequence in a sequence is known as     arithmetic series.For example; 1+2+3+4…….1000000. The first term is and the constant difference is d and the number of terms is n.

Geometric series: A series which involves division or multiplication is known as geometric sequence.It has a constant ratio between terms. For example; 2+6+18+54. The first term is a¡ and the common ratio is r and the number of term is n.

Convergent Series: A series in which there is a limit to the partial sum. For example; 0.9,0.09.0.009,0.0009,…….1. The series converges to 1.

Divergent Series: A series which has no limit. It does not diverge . For example:1, 1+2, 1+2+3, 1+2+3+4,…..

 

3.How can we distinguish between and analyse different types of sequences and series?

Series is a sum of terms which can be arithmetic or geometric. Series are always infinite.If the series have  a constant term its means that its is arithmetic. Where if it has constant ratio it means it is geometric sequence.

Theories , Dinosaur extinction

Posted on

In ToK Class we talked about the scientific method and how it can lead never lead to a absolute truth.In order to reach an absolute truth you need to falsify a lot theories in order to reach one theory.  A lot of theories explain about the extinction of dinosaurs.  Few scientist believe that extinction of dinosaur is related to the falling of meteors while some believe due to volcanic eruption. A lot of theories are accepted as an idea for extinction of dinosaur due to the theories explained and supported by scientist.The acceptance of the theories  is all related to the facts and evidence provided by the scientist. Different theories suggesting different ideologies has lead to a lot of arguments and debates. After reading the article I feel theres no accurate theory that suggest that the reason behind extinction of dinosaur . Theres always a kind of uncertainty associated with each theory. Each theory is based on its hypothesis based on observations and supported by facts to prove it. Its very difficult to explain the duration of time of the extinction of dinosaur and then associate anyone of the theory with it.  To prove any theory we need to consider the variables related to evolution. If any of this theory is disapproved we need to revise our models. Thus coming to a definite truth is difficult .

 

 

The Card Games

Posted on

In this ToK class we played the card games. According to this games we had to give away the card  but each card had its own pattern. We had to follow the pattern . If the card did not follow the pattern it would be rejected and we would end up receiving more cards. We had to be very careful and observe the sequences while giving our kids.

In this activity I learnt that we needed to look at the bigger picture in order to get the and understand the correct sequence.We needed to observe carefully in order to get the correct pattern. The most important thing I learnt was you might be right in your opinions but your right opinions might not be suitable for the situations . Sometimes you needed to falsify your hypothesis or opinions in order to know if its right or not. For example, when we look at scientific  theories we believe it as someone has proved it but we don’t try to falsify to check if its right or wrong.Questioning science might bring more clear theories .Also there are a lot of factors that can affect the outcomes.It is easier to falsify our hypothesis than to prove it right. In class when we tried to falsify our hypothesis we could easily find the patterns. We can never know if all other possibilities are eliminated, we can never know if other theories are correct.

Difference between an EXCELLENT Essay and a moderate essay

Posted on

The first essay is uses a lot of example , the other too but the first one is more clear in terms of concepts as well as in explaining the examples.It also adds to the personal experience and is more engaging. The constant asking rhetorical questions and then answering it makes the more engaged and interested in reading the essay.The first one seemed to be more connected to the the topic in terms of usage examples whereas the second one sometimes seems irrelevant as explaining with the examples. The writer seem to be thinking and unsure when writing. Also in the first essay where the writer highlights the questions with blue and words like ‘disagree’ with blue which makes the writer more engaged in reading what the writer disagrees with and read its point. In the second essay the first fair to analyse all points where is in the first all conceptual ideas are explained and are analysed.

I think  the best way to write a good essay is giving personal examples , asking questions and then answering them , clear ideas and thoughts and keeping the points interlinked with each other.


Peace Boat is a cruise that goes on a voyage around the world and talks about several issues in order to solve some political issue. Peace Boat was going to be there in Singapore and I got an opportunity to visit it. The peace boat had a meeting where the survivor of the Hiroshima and Nagasaki bomb attack survival was going to talk about there experience and why peace is necessary.

When they were speaking about the bomb attacks and how small they were when this incident happen got goosebumps on my body. The told about what time bomb fell and how they managed to escape. I could imagine about the tragic situation. The problems faced by people and the adversity they faced was never seen before in the history.

After hearing the incident I just feel that the greed of power has always affected humanity in the wrong way. It has always lead to the death of people or either destruction of power. I fail to understand that what is the fault of common people in two politicians fight for power.

The bomb attack in Hiroshima and Nagasaki is considered to be the worst war on earth. Peace is very important in this world so that we survive. As the young generation, it’s our duty to maintain peace and work hard to maintain it.

Reflection about the subjects.

Posted on

My subjects are Global Politics(HL),Biology (HL), English B(HL), Maths (SL), Business (SL), Hindi Literature (SL). I think the most justified subject is
English (HL) following which is Hindi. I feel Languages are the most important as this is the only way through which we communicate and exchange are ideologies. As the world is becoming global the sense of communication is increasing . English is becoming the global language through which people are connected and are able to understand each other. Languages not only teach how to communicate but also the skill learnt while learning the languages be it analysing or be it comprehend things they last long lasting. Im believe that if you understand and learn a language you get a better understanding of everything.  The second subject that is important for me is Global Politics. As the name suggest learn about the politics of then world. I feel that as the world is progressing spun need to update yourself about the political issues going around the world. You not only learn the issues but you also learn about the causes and affect of it. You learn about the different forms of power . For example , hard power , soft power , smart power . After having this knowledge I can understand any injustice done using power. I also learn about the human rights, freedom and different concepts related tp it which gives me a better understanding of the world . I feel this are the only subjects where your thoughts and opinions are always given importance and are not considered wrong not right. Theres nothing wrong , nothing right .

I think biology is the least justified subject as you believe in the theory proposed by other scientist . Sometimes you stop challenging the theories. Also business is based upon the strategies that successful businessmen or companies have adopted and you study it. You refer to others ideologies and strategy to have a successful career ahead.

 

 

 

Inkling- Logo , First task

Posted on

Today I was actually really excited to see the inkling logos everywhere in the school as a way to promote the school magazine. I was also nervous as now people are going to see my work online. I know people were going to read it but this was the first time I actually felt that the whole school is going to read it. There is always a fear in me that I might be judged on something and I feel sometimes it’s not good enough to be in front of people but then there was also a sense of pride as its going to be my magazine, my work.

Today we were also assigned our task about how and what are we going to do. We were supposed to think carefully about what we want to submit. Every piece should have to have a meaning on what I needed to do as it was going to be a school magazine and nothing should be offensive to anyone. I had to carefully think about my work and decided that I will try at least to submit 10 pieces of work.

My first submission was about the boarding house weekend away followed by culturama. About culturama, I had decided to take photos of Ethiopian dance and what I learnt throughout my journey.

The main problem I feel that I will face apart from my language issue is time management. I think I might face a problem in managing my school work and submission dates. I will try to complete my inkling work during the lunch meeting on Monday.
