As would be expected fingerprints have been around as long as man has, and thus the first human to look at their hands would have discovered fingerprints. I assume that in this question you are asking who realised that they could be used as a method of identification. This has been known for thousands of years, in fact in early civilisation the distinctive fingerprint of a person could be found on pottery created by that person as way of a hall mark.\nNehemiah Graw (1641-1712) was one of the first people to study the distinct ridges of the fingerprints, and the science of their study developed through such people as Marcello Malpighi and Thomas Bedwick. The first person to realise that fingerprints were so distinctive they could be used fairly accuratly as a means of identification was Sir William Herschel (1833-1917), but it was Dr Juan Vucetich who started up the worlds first fingerprint buereu in argentina, and this became the first country in 1896 to abolish athropometry as a means of identification, in favour of fingerprints.

The invention of the microscope is variously accredited to Zacharias Janssen, a Dutch spectaclemaker, c.1590, and to Galileo, who announced his invention in 1610.

Actually, they're more similar than you might think.  Any contact lens has to be prescribed by an eye doctor because contacts are technically medical devices.  Contacts come in many different sizes and fits, so your eye doctor has to select a lens that fits your eye properly and lets enough oxygen through.  If your contacts don't fit you correctly, serious damage to your eyes can occur.  What you mean by cosmetic contacts is probably colored contacts that don't have any power (prescription) in them.  These can be fit and prescribed by your eye doctor as well.

When I first got my contacts I had trouble putting them in. Then I tried this: put the lens on the tip of your finger, before you put the lens on your eye look up (with your eyes only), pull down the bottom lid of your eye and put the lens on your eye (it will be on the white part). Then while you are still holding the lens on your eye look right into it. Then remove your finger. I do this every morning and it works great!

Overnight Monthly-wear contact lenses. They're one-way oxygen permeable.

Please DO NOT wear your contact lenses in either eye if even one of your eye is red.\n\nIt is again not possible to wear contacts in only one eye as this will affect your stereopsis and u may land up having confusions and very very annoying vision esp while driving when u need a lot of concentration.\n\nIf your eyes are red, discontinue the lenses and consult your doctor immediately\n\nZubin J\nOptometrist

Contact lenses offer no protection against chemicals--in fact it is more dangerous to wear them than not.  If there are lots of chemical vapors in the air, they will end up accumulating underneath the lens (gas permeable lenses are slightly better, but I still wouldn't wear them in a chem lab).  Furthermore, if you get something in your eye and you need to wash it out, the contact lens will prevent effective cleaning.

The first person who proposed that the Earth orbited the Sun was Aristarchus, about 300BC, but his writings have been lost. In 1530 Copernicus published his theory that the Earth orbits the Sun. In 1609 Galileo first used a telescope to view Jupiter's moons. In 1630 Galileo published a document upholding the Copernican system but was forced to recant his beliefs by the inquisition in 1633.

I do not think the picture exists.  Salvino D'Armate lived in 13 century and is credited with the invention of eye glasses in yr about 1284. Photography was invented in 19 century.

Augustine Fresnel invented the Fresnel lens. (used in lighthouse)\n\nspotlight or searchlight, In 1892 such apparatus was used along the English Channel ( I was thinking it goes back to the ancient Greeks)\n...\nIn 1916 Edison invented a portable electric apparatus powered by storage batteries. ... The electric arc was generally employed after the American inventor E. A. Sperry introduced (1915) his high-intensity arc lamp based on principles that still predominate in modern searchlight equipment.
