Samuel Morse delivers the first message by telegraph. Morse invented the telegraph, which relayed messages by electricity. This enabled communication over great distances. http://www.survivingtheaftermath.com/index.php/necessities-skills/57-how-to-make-your-own-telegraph-machine http://www.history.com/topics/inventions/telegraph

It is in this year, (exact date unknown) Daimler creates a prototype of the modern internal combustion engine. This transforms chemical energy (fuel) into mechanical energy. This is the basis of engines we use in cars. http://www.infoplease.com/encyclopedia/science/internal-combustion-engine-evolution-internal-combustion-engine.html http://me-mechanicalengineering.com/internal-combustion-engines-classification/

Marconi successfully send the first radio tramsmission across the Atlantic Ocean. This tramsforms electrical energy into radio waves. This was a big step for long distace communication, and is the model for all wireless communication. http://www.history.com/this-day-in-history/marconi-sends-first-atlantic-wireless-transmission http://www.keyword-suggestions.com/Z3VnbGllbG1v/

The first successful atomic bomb blast is performed in New Mexico. This transforms matter into heat and radiation as a form of energy. The same technology is later used for the bombs dropped in Japan. minersco.com http://www.history.com/this-day-in-history/the-first-atomic-bomb-test-is-successfully-exploded
