Introduction Mathematics is an indispensable subject of study. It plays an important role in forming the basis of all other sciences which deal with the material substance of space and time. What is Mathematics? Mathematics may be described as the fundamental science. It may be broadly described as the science of space‚ time and number. The universe exists in space and time‚ and is constituted of units of matter. To calculate the extension or composition of matter in space and time and to

[edit] Mathematics [edit] Pi as irrational Aryabhata worked on the approximation for Pi (π)‚ and may have come to the conclusion that π is irrational. In the second part of the Aryabhatiyam (gaṇitapāda 10)‚ he writes: caturadhikam śatamaṣṭaguṇam dvāṣaṣṭistathā sahasrāṇām ayutadvayaviṣkambhasyāsanno vṛttapariṇāhaḥ.

Chapter 2: THE NATURE OF MATHEMATICS Mathematics relies on both logic and creativity‚ and it is pursued both for a variety of practical purposes and for its intrinsic interest. For some people‚ and not only professional mathematicians‚ the essence of mathematics lies in its beauty and its intellectual challenge. For others‚ including many scientists and engineers‚ the chief value of mathematics is how it applies to their own work. Because mathematics plays such a central role in modern culture‚
