Archimedes’ Principle

Archimedes is considered by many as the greatest scientist of the ancient world.

Metallurgical Engineering

Metallurgical engineering is the study of metals.

WHAT ARE THE PROPERTIES OF CONDUCTORS AND INSULATORS?

A good conductor allows the electric current to pass through it freely while an insulator does not allow the electric current to pass through it. Conductors are mostly metals like copper. Insulators are mostly non-metallic solids which have extremely high resistance towards the flow of charge and do not allow the charge to flow through them.

The Modern Periodic Table

The periodic table is an arrangement of the chemical elements, organized on the basis of their atomic numbers, electron configurations and recurring chemical properties.
