The capacity for people to grow despite facing hardships and obstacles has continued to excite me and engage me intellectually because of the prospect of further expansion and development
^You do not really need to begin with that line.
I was introduced to
concept of evolution when I was in middle school and I took a class trip to the Jet Propulsion Laboratory in Pasadena. This trip proved to be not only one of the most intellectually engaging experiences of my life, but also one of the experiences that has driven me to work harder in academics in order to achieve my aspirations.
What I have highlighted in bold, is what I think is just a giant cliche.
At the time, it blew my mind to think of an airplane travelling from one side of the nation to the other,
^Even when you were well into high school, the thought of an airplane travelling from one end of the Earth to the other was 'mind blowing' to you at the time? Ok, well I guess that is you then.
and here was a craft travelling
billions of miles to the end of the galaxy.
^It was a project under development. How was it 'travelling'.
While this event triggered a short-lived obsession with engineering, it sparked an even greater interest within me.
^Perhaps you can specify the branch of engineering; aeronautical engineering.
I became spellbound with the idea of indefinite human growth, and even to this day, I hold this memory close to me.
^I think readers would understand that it is a close memory if you decided to talk about it in your application essay.
By the way, human growth does not seem to be the right word. It is as if you are implying that we can physically continue to grow. Whilst this may be true, I do not think that this is the track you want to be on...
As an aspiring physician, I can only hope for greater development in the field of medicine, and to me, this ongoing journey to Pluto is a sure sign of advances in all fields of studies.
I think mankind in general relies on greater development for medicine. Your sentence structure implies that because you are an aspiring physician, that is why you hope for greater development in medicine..is this the case? If you were not an aspiring physician, then would you not want greater development in medicine?
The ongoing journey to Pluto is not an advancement in the field of English Literature. So I would not say all 'fields of studies'.
Although progress may be slow and at times stagnant, this mission has led me to believe that mankind is undoubtedly continuing to move forward.
To what extent can you consider it slow?
Look, you were meant to discuss an idea or event that you found intellectually engaging. Alright, you decided to go for the Jet Propulsion event. You do not develop how you found that event intellectually engaging.
You just say, literally, 'I went to this event. There was a mission to go to Pluto. It is amazing. Mankind is taking a giant step forward.'
I also do not see what is the point of mentioning being an 'aspiring physician' because neither is it relevant to your essay, nor the essay question. You also talk about your brief interest in engineering. What made it brief? Your whole essay focuses on an 'intellectually engaging event' that centers around engineering...what just made that interest fade away. It kind of implies that perhaps, you did not really find this event that intellectually engaging to begin with.
