Visual symbols are essentially the language of metaphysics. From this point of view, each manifested object, both natural and human, or activity, or a thought becomes a typical symbol pregnant with meaning.
Each symbol to us is Vidhya. अग्नि विद्या, गणपति विद्या, गो विद्या गृह विद्या and the list goes on covering all words of Veda.
मुण्डक उपनिषद्, Muṇḍaka Upaniṣad divides knowledge into two parts:
1) The knowledge that leads to Self Realization is called Para Vidya (Great or Divine Knowledge) and
2) everything else is called Apara Vidya or Knowledge of Material world (wordly knowledge).
Though Apara Vidya enables one to earn ones bread and helps one to understand each object of universe separately, it does not show the Ultimate Reality (Akshara) or Root Cause of this universe.
Knowledge of Apara vidhya relies on codes/language. Physics, biology, mathematics etc are different aspects of Apara vidhya.
Any progress in mankind’s limits of Apara vidhya relies on quantum leaps received in meditative states (Para Vidhya or Self-realization). Some scientists admit it and some not. But it is true that the hints for progress were never codified in languages. They were pure intuitions blessed by “THEM” as per movie interstellar. In case of Indian mathematician, it was his native goddess who gave him hints in dreams.
So the point here is:
Lower sciences (Apara) – can be described by language
Higher Science (Para) – You can not have language based theory of experiencing subjects. You can intuitively reflect it by mind.
Movie interstellar has touched the limit of Apara, crossed the limit and tried to explain Para using language of Apara.

100-year-old deathbed dreams of mathematician proved true
While on his death bed, the brilliant Indian mathematician Srinivasa Ramanujan cryptically wrote down functions he said came to him in dreams, with a hunch about how they behaved. Now 100 years later, researchers say they’ve proved he was right.
“We’ve solved the problems from his last mysterious letters. For people who work in this area of math, the problem has been open for 90 years,” Emory University mathematician Ken Ono said.
Ramanujan, a self-taught mathematician born in a rural village in South India, spent so much time thinking about math that he flunked out of college in India twice, Ono said.
But he sent mathematicians letters describing his work, and one of the most preeminent ones, English mathematician G. H. Hardy, recognized the Indian boy’s genius and invited him to Cambridge University in England to study. While there, Ramanujan published more than 30 papers and was inducted into the Royal Society.
