Tool of Modern Man2000 AD
Made of metal, plastics, electronic materials, etc.Manufactured using tremendous scientific efforts
Tool of Primitive Man200,000 BC
Made of stone (a ceramics !!)Collected directly from nature
Without materials, there is no engineering !!

P f i f i l d ll i l i i l
Profession of mechanical, civil and other engineers involves‘engineering with materials’
i.e., they use materials in their creation
Profession of materials and metallurgical engineers involves‘engineering of materials’
i.e., they engineer materials to satisfy the needs of others
