Some of Johannes Kepler's inventions are the refracting telescope, eyeglass lenses, Rudolphine tables, log books and the discovery of a supernova. His works and ideas guided many famous scientists like Isaac Newton to develop their ideas.Know More
Kepler worked with lenses used in eyeglasses to help both far and near-sighted people see accurately. He developed lenses that corrected people's vision and enabled the average person access to affordable glasses. His fascination with the movement of the planets and other heavenly bodies led to his invention of a refracting telescope to provide a better tracking of planetary systems. The images from Kepler’s telescope could be projected to a white screen to track their movements.
Kepler invented log books to help him keep a complete record of his observations. He wanted to create a permanent record for his observations to aid other scientists in observing the heavenly bodies. He documented information about the stars in a star catalog called the Rudolphine tables, which he named in honor of Emperor Rudolf. Most of the stars recorded in the Rudolphine tables were very accurate, and it became the first table with atmospheric refractions. These inventions led to his standing as a prominent scientific mind.Learn more about Inventions

Johannes Kepler's theories of the universe were notable for hypothesizing that the universe was created on April 27, 4977 B.C. and that the planets orbit in an elliptical pattern rather than a circular pattern. His theory superseded previous theories which postulated that planets move in circular orbits at constant speeds.Full Answer >
Johannes Gutenberg's successful use of his newly invented movable-type printing process established the groundwork for the widespread and commercial mass production of printed books and ushered in a wave of social changes throughout Europe. Printed materials became plentiful and affordable, which helped spread communications and new ideas to significant portions of society that previously had little or no access to them. Gutenberg's printing method enabled books to develop into an economically feasible form of communication and learning that helped bring about cultural, political and academic changes that permanently altered the course of history and the structure of society.Full Answer >
The earliest working telescope design is attributed to Dutch eyeglass maker Hans Lippershey, who applied for a patent to his design in 1608. Two other Dutch eyeglass-making contemporaries of Lippershey, Zacharias Janssen and Jacob Metius, had developed similar telescope designs in the same year.Full Answer >
