A glass of wine vibrates at a regular frequency, and a high musical note can break such a glass. The frequency of the musical note must be equivalent to the natural frequency of the glass. Because the frequencies of the note and the glass are the same, the energy is transferred to the glass, which vibrates so violently that it shatters. The phenomenon is known as resonance. The technique can be used to improve the sound of some musical instruments.

An accountant told us that he loves his work because as long as he follows his checklist, he knows he’s doing a good job. A professor hates rules and needs to set his own agenda. They both do their jobs well, but they’d be disasters in the other’s position. Just like everyone else, people with ADHD need to understand their strengths and weaknesses and find or build an environment that will help them thrive. We know people who are the first at work to volunteer for jobs that suit their skills, so they don’t get stuck doing the ones that aren’t a good fit.

It wasn't until the Series automobiles appeared that the grilles shrunk substantially enough to be considered conventional.

Very few countries measure things using the Imperial System. This means that they measure weight in pounds and distances in inches rather than the more common kilograms and centimeters.

Universal, on the other hand, had little trust in Lucas to carry out an idea with such economic potential. Disney's refusal was the most ironic, prompting Lucas to turn to Fox. In 2012, however, Disney paid $4 billion for the property.

Venetia Burney suggested the name Pluto after the Roman god of the Underworld after her grandpa informed her about the newly found planet. Pluto the planet, like the God, sat in the furthest ends of the solar system, thus it felt appropriate.

Pluto piqued the interest of astronomers since the first two letters of the name are Percival Lowell's initials.

So, in order to increase his productivity and save crucial study time, he decided to add wheels to his beautiful recliner.
