Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

Timeline of microscope technology

c. 700 BCE - The "Nimrud lens" of Assyrians manufacture, a rock crystal disk with a convex shape believed to be a burning or magnifying lens.
167 BCE - The Chinese use simple microscopes made of a lens and a water-filled tube to visualize the unseen.
13th century -  The increase in use of lenses in eyeglasses probably led to the wide spread use of simple microscopes (single lens magnifying glasses) with limited magnification.
1590 - earliest date of a claimed Hans Martens/Zacharias Janssen invention of the compound microscope (claim made in 1655).
After 1609 - Galileo Galilei is described as being able to close focus his telescope to view small objects close up and/or looking through the wrong end in reverse to magnify small objects. A telescope used in this fashion is the same as a compound microscope but historians debate whether Galileo was magnifying small objects or viewing near by objects with his terrestrial telescope (convex objective/concave eyepiece) reversed.
1619 -  Earliest recorded description of a compound microscope, Dutch Ambassador Willem Boreel sees one in London in the possession of Dutch inventor Cornelius Drebbel, an instrument about eighteen inches long, two inches in diameter, and supported on 3 brass dolphins.
1621 - Cornelius Drebbel presents, in London, a compound microscope with a convex objective and a convex eyepiece (a "Keplerian" microscope).
c.1622 - Drebbel presents his invention in Rome.
1624 - Galileo improves on a compound microscope he sees in Rome and presents his occhiolino to Prince Federico Cesi, founder of the Accademia dei Lincei (in English, The Linceans).
1625 - Francesco Stelluti and Federico Cesi publish Apiarium, the first account of observations using a compound microscope
1625 - Giovanni Faber of Bamberg (1574 - 1629) of the Linceans, after seeing Galileo's occhiolino, coins the word microscope by analogy with telescope.
1655 -  In an investigation by Willem Boreel, Dutch spectacle-maker Johannes Zachariassen claims his father, Zacharias Jansen, invented the compound microscope in 1590. Zachariassen's claimed dates are so early it is sometimes assumed, for the claim to be true, that his grandfather, Hans Martens, must have invented it. Findings are published by writer Pierre Borel. Discrepancies in Boreel's investigation and Zachariassen's testimony (including misrepresenting his date of birth and role in the invention) has led some historians to consider this claim dubious.
1665 - Robert Hooke publishes Micrographia, a collection of biological micrographs.  He coins the word cell for the structures he discovers in cork bark.
1674 - Anton van Leeuwenhoek improves on a simple microscope for viewing biological specimens.
1850s - John Leonard Riddell, Professor of Chemistry at Tulane University, invents the first practical binocular microscope.
1863 - Henry Clifton Sorby develops a metallurgical microscope to observe structure of meteorites.
1860s - Ernst Abbe discovers the Abbe sine condition, a breakthrough in microscope design, which until then was largely based on trial and error. The company of Carl Zeiss exploited this discovery and becomes the dominant microscope manufacturer of its era.
1928 - Edward Hutchinson Synge publishes theory underlying the near-field scanning optical microscope
1931 - Ernst Ruska starts to build the first electron microscope. It is a Transmission electron microscope (TEM)
1936 - Erwin Wilhelm Müller invents the field emission microscope.
1938 - James Hillier builds another TEM
1951 - Erwin Wilhelm Müller invents the field ion microscope and is the first to see atoms.
1953 - Frits Zernike, professor of theoretical physics, receives the No ...
