1877 – Thomas Edison completes 1st model of the phonograph, a device that recorded sound onto tinfoil cylinders

The phonograph is an instrument that reproduces sounds through the vibration of a stylus or needle following a spiral groove on a revolving disc or cylinder. In 1877, Edison was working on a machine that would transcribe telegraphic messages through indentations on paper tape, which could later be sent over the telegraph repeatedly. This development led Edison to speculate that a telephone message could also be recorded similarly on tinfoil cylinders. Later it was known as a gramophone. Phonograph offered future possibilities like Letter writing and all kinds of dictation without the aid of a stenographer, phonographic books for blind people, educational purposes, reproduction of sound/music, etc.

2018 – NASA launches the Parker Space Probe, its first mission to the Sun and its outermost atmosphere

Parker is a scientific mission to unlock the mysteries of the Sun’s corona (outermost atmosphere of the sun) and solar wind. Parker uses breakthrough technology and autonomy to endure heat and radiation like no other mission. It will orbit within 4 million miles of our star’s surface to study the formation of the solar wind. This is the first mission named after a living scientist: Dr. Eugene Parker, who theorized the existence of the solar wind. The observations made could help solve the coronal-heating and particle-acceleration puzzles. It will also give a better idea of how stars tick in general. Till now Parker has been successful in finding five new studies regarding sun like the dust-free zone around the sun, switchbacks given off by the sun’s magnetic field, turbulence in solar winds, and small particles release.
