In India, for example, there are a limited number of competent researchers, and most of the research is not methodologically sound. Collaborative researchĬollaboration has long been important for the advancement of science, and the advent of scientific journals has only strengthened this notion. He suggested that the two convex lenses used in Kepler’s telescope would give an upside-down image. Johannes Kepler also had an idea for an improved telescopic device. However, Galileo’s telescope was over four feet long and could magnify an object thirty times. The only visible part of the Moon was seen with these instruments. The first reflecting telescope was constructed in 1668.Īnother early refracting telescope had a limited field of view. The secondary mirror allows for minimal obstruction to the objective mirror. In addition to using a spherical mirror, Newton also made a second “diagonal” mirror near the primary mirror’s focus. Isaac Newton was able to correct chromatic aberration by using a spherical mirror. Other early refracting telescopes were known for their flaws.

Because reflecting telescopes use mirrors instead of prisms, their images have diffraction spikes and rings. Reflectors do not produce perfect images, but they do give us a clear image of distant objects. A thin layer of aluminum is vacuum-deposited onto the front surface of the primary mirror. Modern reflecting telescopes feature a solid glass cylinder with the front surface ground into a parabolic or spherical shape. Developed by Isaac Newton in 1668, reflecting telescopes are now used to detect radio waves and other electromagnetic wavelengths. These devices can even detect ultraviolet, gamma, and x-rays. Unlike ordinary telescopes, reflecting telescopes can see a wide range of colors and can gather light that our eyes cannot see. Reflecting telescopes help scientists observe distant objects by collecting light and creating images. One of the first breakthroughs in the revolution came from Nicole Oresme, who investigated whether the Earth or the Sun moved.

More people could access the information and the new tools of long-distance navigation allowed for an explosion of ideas. The new technologies of the time, including the printing press, made the ideas and discoveries spread like wildfire. Religion still influenced scientific thinking. The Scientific Revolution began slowly, piece by piece, with people holding many of the same ideas they had held for more than 200 years. How New Technology Helped the Scientific Revolution
