To define the knowing of a particular thing like nature,society ,many disciplines and their sub-branches have been evolved.
If you curious to know about stars,galaxies,forces,waves,motion,heat etc. you have to go through physics and some interconnected subjects like astronomy,geography but each subject only requires certain applications of a phenomenon.
To understand something deeply takes a great amount of time,sometimes it might be annoying but the determination to achieve a thing,and perseverance to keep your work continue and patience are the building-block elements of a person and consistency and curiosity are the food of success.
Understanding is not a word but merely a feeling through which u can communicate without rendering a word it doesn't need any degree or liberal education.How many people are strolling around you,getting qualified with higher degrees but they are unable to connect their learning with the world.why is this so?
just because they lack in understanding of things.you may give lot of your precious time for getting pieces of papers from many recognized prestigious institutions across the world and umpteen of people has done so but Fewer of them are just working under those who has applied their learning in everyday life.
why do we study?
simply to improve our life and ameliorate situations lying in.
Fewer leaves their footprints behind and many lost lives like a tree does it really become to a person.
many famous figures sensed the meaning of life through understanding in every field from science to spiritualism let us take examples
Elon Musk the richest person and founder of SpaceX and CEO of TESLA,
Bill gates who dropped liberal education to live his life using experiences and understanding,
Ratan tata one of the greatest business tycoons and philanthropist from india also dropped the liberal education and
Swami Vivekannada without any philosophical degree get famoused in a night for his Chicago speech delivered in 1893 and many such names you come across.
Its better to make sure wheter your learning touching the right path or you are just being lost in the trap of words written by some scholars.
Whatever you learn it should be useful in the realm of your dreams if it is, there is nothing to be worried about.
Make your education useful asking questions why, how,when and what these help you increase your understanding..
