Definition: Siemens (1857-1916) was a German industrialist, inventor, and philanthropist who founded Siemens AG in 1892 as an engineering company. He worked on many innovations that transformed the automotive industry, including the first electric motor for automobiles. The word "Siemens" is a shortened form of "Sicherheit", which means "safety". It was often used by Siemens employees to describe their work and commitment to improving the safety of machines and industrial processes. In 1893, Siemens introduced the first electric motor in Germany. The introduction of this new technology revolutionized the automotive industry and transformed its products from mechanical to electronic control systems. This innovation led to a significant increase in production efficiency and the development of mass market automobiles. Today, Siemens AG is one of the world's leading manufacturers of electric vehicles (EVs) and industrial automation solutions, with more than 10,000 employees worldwide. The company's focus on sustainability has led it to receive numerous awards for its efforts towards reducing environmental impact.

Definition: In the International System of Units, the derived unit of electrical conductance; the electric conductance in a body that has a resistance of one ohm. Symbol: S

Alright class, settle down, let’s take a look! Today we’re tackling ‘siemens,’ a fascinating unit indeed – it’s quite a treat! The dictionary gives us the key, you see, “A derived unit of conductance, electrically free!” Now, think about this: what is electrical flow? It's like water rushing, a current we know. Resistance stands in its way, a stubborn fight, But 'siemens' measures how easily things might... …flow through that resistance, quick and bright! A body with one ohm – it’s quite the sight! So, ‘siemens,’ or ‘S’, is the measure you need, Of how well a material conducts, indeed! Does anyone have any questions? Don't be shy, Let’s explore this concept until we truly fly!
