Satyam-Shivam-Sundaram

alO,

Any branch of Knowledge can be broadly classified or parameterized based on three aspects

1) Truth (Satyam)

2) Welfare (Shivam)

3) Beauty (Sundaram)

Truth -- Sciences, Welfare -- Technology, Beauty --Arts.

"Truth/Sciences" emphasize on verifications, "Welfare/Technology" aims at making known things useful and "Beauty" is there to feel/enjoy.
