Theoretically it should be possible to an extend, however usually what one is able to pick up with open astral senses is limited by what they can perceive.
If you have no experience with math or physics, it is unlikely your astral senses can pick up on advanced maths or physics formulae, as the pineal gland has to translate what it picks up on in a form that your brain can make sense of.
If you do not possess the knowledge to understand the information the pineal picks up on, it will mostly come to you as something unintelligible.
Likely you'll understand you came upon something extraordinary, and you will realize you are dealing with advanced mathematics or physics, but you'll be aware that you lack the knowledge to understand it and that the true essence of the information went over your head.
Study and gaining real understanding of subjects is still required in order to gain and make use of advanced knowledge through your astral communication and psychic ability.
Imagine being told something in Chinese, and you've never studied it before. Even if someone tells you perfectly clear, you'll likely be unable to perfectly repeat what was said to you, let alone have any clue what it means, or be able to perfectly transcribe it onto paper for someone who does understand to make sense of it.
With astral communication it is similar to that. Everything you can know and gain from it is limited by what you can perceive.
The broader your knowledge and understanding, the greater your perception and the more you can gain through your psychic ability.
