Metallic microlattice is so light that a dandelion head can support it without being crushed.
Can you name the lightest metal? Most metals are heavy or dense, yet some metals can float on water while others are nearly as light as air. Learn about the lightest elemental metal and the lightest alloy. Lightest Metal That Is an Element When we talk about a material being […]

What Is the Lightest Metal?

In addition to the prestige of winning an event at the Olympics, the victor receives a gold medal. At one time, Olympic gold medals were real solid gold. However, the last time a solid gold medal was awarded was at the 1912 Stockholm Olympics. Modern Olympic gold medals are sterling […]

Are Olympic Gold Medals Real Gold?

A resistor has high electrical resistance while a conductor has high conductivity. (Nicolas Thomas)
This is a table of the electrical resistivity and electrical conductivity of several materials. Included are metals, elements, water, and insulators. Electrical resistivity, represented by the Greek letter ρ (rho), is a measure of how strongly a material opposes the flow of electric current. The lower the resistivity, the more readily the […]
