From what I understand, the word midnight is usually interpreted incorrectly. Midnight is written as 12am which would imply that it's in the morning. Therefore, it should be at the start of the day. On the other hand, both Dictionary.com and the Oxford Dictionary define it as twelve o'clock at night.
James Prescott Joule. The English physicist James Prescott Joule (1818-1889) proved that mechanical and thermal energies are interconvertible on a fixed basis, and thus he established the great principle of conservation of energy.
1 Joule is the amount of work done when a force of 1 Newton moves any point mass by a distance of 1m. For a unit of Joule to be used for a unit of Torque, you would need a unit of Torque to always perform 1 Joule of work, which is not true.
