Viruses. They are smaller than the average wavelength of light and as such are not viewable unless an electron microscope is used.

You should have payed attention in class what hehe
A compound microscope
Because it is made up of more than one lens. A simple microscope is make up of one lens (a hand held magnifying glass can also be considered as a simple microscope). In a compound microscope, one cannot see the magnified image until both the lenses are used.

There there are many. Simple microscope, compound microscope, light microscope, scanning electron microscope, TEMicroscope, Dissection microscope, etc and most of them are used to see small cells that cannot be seen by the naked eye.
Light microscope cannot be used. An electron microscope houl b used
Short answer: Zacharias Jansen Long answer: Your question is not valid for 2 reasons: 1. You cannot "discover" something if it does not exist. You should be asking who invented it, not who found it laying around somewhere. 2. A "simple microscope" is not common terminology. Simple compared to an electron microscope? or simple compared to a compound microscope? What is typically referred to as just "microscope" is technically a compound microscope. A set of multiple lenses mounted in a desktop style that allows the compounding of magnification. A compound microscope is the standard microscope in any basic lab setting. Anything more "simple" than a compound microscope would not even really be a microscope, it would either be a telescope, or simpler than that is a magnifying glass (with a single lens) The inventor of the magnifying glass was: Roger Bacon The next step up is the telescope invented by: Zacharias Jansen The next step up is the "compound microscope" which was also invented by: Zacharias Jansen (this is the simplest form of what would be recognized as or named "microscope") If you wanted to go even "simpler" and define microscope as anything that magnifies, there were reading glasses around for thousands of years prior, and even "reading stones" which were lumps of polished glass used to magnify parchment in Egypt as far back as 7000 B.C. (inventor unknown). So it really depends on how you wish to refine your meaning of simple. The magnification of anything? There is no known inventor for reading stones, his name is lost to time. Or if you mean the first invented microscope that could examine things too small for a human eye to detect, that's a compound microscope. Thus if I am guessing your meaning correctly, you meant to ask this question: Question: Who invented the compound microscope? Answer: Zacharias Jansen
The word Dimension merely suggests an attribute, not just a linear measure.Thus Time is commonly referred to as the 4th dimension, for we can not measure its attributes with only length, height, and width.And degrees of rotation cannot be described with just L,W,H, and so on.Dimension is just the name of a concept, and we need a new dimension when the property we wish to describe/measure may not be able to be measured in terms of the existing dimensions.
A continuum of a measureable quantity that cannot be resolved from a linear arrangement of any other dimensions. Usual dimensions might be space and time, measured with three orthogonal spatial axes and one for time.
millimeter is linear dimension; squaremeter is area dimension. so i feel that there cannot be a conversion.
