Why we might never find all the answers


 Since I was little I always loved sci-fi movies. Expolring the universe and interstellar journeys fascinates me even right now. Recently, I've been particularly interested in the first human journey to Mars. right now NASA with cooperation with other international companies are testing new rockets and technology that would be able to take men kind to Mars in the near future. I watched plenty of documentaries and conferences about the obstacles that right now unables NASA to complete this mission.


2 particularly interesting videos about sending humans to Mars which made me think about this issue

 As I was watching I thought a lot about the obstacles that scientists need to overcome in order to send humans to Mars. Of course the cause of these obstacles is our current knowledge which unables scientists to produce more technologically developed devices.  But what is really an obstacle? Is it our knowledge or is it the important materials which do not exist? Can our knowledge be an obstacle in gaining new knowledge? 
 On the one hand our (as all humans') knowledge has biases. We may tend to think that a certain claim could never be true because our intuition tells us that or even reason. Many past ''crazy'' ideas are right now are fundamental and common knowledge which helps our world to function as we are used to.  For example Newton's laws, they enable us to calculate speed, time or displacement during every-day journeys. Without them we wouldn't even have speedometers in our vehicles!
 However, on the other hand as Newton said :
If I have seen further than others, it is by standing upon the shoulders of giants.

we build our current knowledge on the previous one. Without Newton's laws we wouldn't have speedometers, without inventing mathematics and number we wouldn't be able to build complicated and stunning buildings and so on. Thus, the knowledge gained on the past helps to develop current one. In certain cases it is even necessary to posses firstly fundamental knowledge in order to apply more complicated structures into the real world. In the mathematics, for example, we need firstly know simple substractions, muliplication, adding ect. to then move on to more complicated equations and formulas to finally be able to do statistic measurements in various experiments.

 Being always open-minded and at the same time looking at the current and past knowledge might be hugely important in exploring the unknown. Sometimes it is doable, however in many cases it might be the reason of never finding the answer to the questions that human race faces.

I'll see you next week,
Alicia.

Unseen knowledge

Some time ago my friend told me this short story: I was going time from school by bus. That day I felt a bit annoyed because I forgot to take my headphones and my way back home looks as if it's going to be quite long because of the traffic in the city. So I sat be the window next to a group of teens. Sitting next to them I heart their school stories, what they did today at school and so on. You might think that it is just a normal, everyday situation, but I started to think: Well, I go back go by bus every day for past 6 six or so. However, I cannot remember listening that kind of conversations were I was 9. I remember talking and hearing about some children TV shows or new toys someone received. Does it mean that I did not hear conversations about more teen issues just because I was not a teen or I wasn't interested in that topics?   My friend is also an IB student so we started to think and discuss this question. From the previous question the knowledge question arose Can

Am I an expert?

Last week I was going back home with two of my brothers and my dad from the family trip. As we were talking, suddenly I realized that my little brother, who is now seven, kept asking many questions and when my other brother or I answered to his question he still waited for my father's answer. Firstly I thought that it might be because our dad is his role model and then he believes that my father has greater knowledge so  naturally he is more likely than me to answer correctly. This got me thinking about experts. In this situation, my dad was an expert and my little brother-a person which desired knowledge. We can observe that in media, especially tv news or in newspapers, when analyzing a global, political or any other issue mostly the experts occur and provide not also the historical facts and scientific theories, but also their point of view. Of course in the ideal world, when each person thinks critically and independently, he or she can create their own opinion by looking for
