the scale of atoms.
It is used in the pickups of some electronically amplified guitars and as triggers in most modern electronic drums.[7][8] The piezoelectric effect also finds everyday uses, such as generating sparks to ignite gas cooking and heating devices, torches, and cigarette lighters.

piezoelectric inkjet printing, generation of high voltage electricity, as a clock generator in electronic devices, in microbalances, to drive an ultrasonic nozzle, and in ultrafine focusing of optical assemblies. It forms the basis for scanning probe microscopes that resolve images at

The inverse piezoelectric effect is used in the production of ultrasound waves.[5]

French physicists Jacques and Pierre Curie discovered piezoelectricity in 1880.[6] The piezoelectric effect has been exploited in many useful applications, including the production and detection of sound,

For example, lead zirconate titanate crystals will generate measurable piezoelectricity when their static structure is deformed by about 0.1% of the original dimension. Conversely, those same crystals will change about 0.1% of their static dimension when an external electric field is applied.

The piezoelectric effect is a reversible process: materials exhibiting the piezoelectric effect also exhibit the reverse piezoelectric effect, the internal generation of a mechanical strain resulting from an applied electric field.

The piezoelectric effect results from the linear electromechanical interaction between the mechanical and electrical states in crystalline materials with no inversion symmetry.[4]

is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in response to applied mechanical stress.[2][3]

Calling his disciples to him, Jesus said, ‘Truly I tell you, this poor widow has put more into the treasury than all the others. They all gave out of their wealth, but she, out of her poverty, put in everything—all she had to live on.'” – Mark 12:41-44

Just be kind to people

He did much evil in the eyes of the Lord, arousing his anger.

5 In both courts of the temple of the Lord, he built altars to all the starry hosts. 6 He sacrificed his children in the fire in the Valley of Ben Hinnom, practiced divination and witchcraft, sought omens, and consulted mediums and spiritists.

4 He built altars in the temple of the Lord, of which the Lord had said, “My Name will remain in Jerusalem forever.”

Israelites.
3 He rebuilt the high places his father Hezekiah had demolished; he also erected altars to the Baals and made Asherah poles. He bowed down to all the starry hosts and worshiped them.
