Is there any limit to size?

Trying to scale down a microscope to a submicroscopic microscope to get finer resolution would not work. The molecular density of the materials and the wavelengths of the light would not scale down.

Living cells also have a limited range of sizes. Issues like surface tension, ratio of area to volume, permeability, size of protein, lipid, and DNA molecules, etc. prevent them from being scaled too large or too small. The large organisms we see every day are multicellular. Ultramicroscopic reproductive particles like viruses have a structure simpler than bacterial cells and are always obligate intracellular parasites.

In a sense a bacterium or virus "sees" or at least detects things extremely tiny distances away in their environments. That could be loosely interpreted as functionally analogous to looking through a little bacteria microscope, but the structure of these detection mechanisms is very, very different from what works on larger scales.

The practical magnification limit is about twice the wave length of light for both very large and very small microscopes. Electrons have shorter wave lengths, so electron microscopes can have higher magnification. Limits occur for both larger and smaller in most any topic. It is generally thought that nothing can be smaller than plank length. There may be no other dimensions to peer into, so that was speculation. Neil

proscribing crowds at a rally is wide-spread observe between campaigns. generally for cover motives yet in addition for outcomes. i've got a relative that worked for the George Bush campaign returned in 2000 and maximum of those rally crowds are staged with supporters of the candidate to make it look basically like the candidate has momentum. generally early interior the campaigns. So, electorate fairly have have been given to be careful in case you're staring at those rallies on the information. Politicians create sound bites at those rallies with a propped up crowd making it look like they have wide-spread help from the electorate. it fairly is all smoke and mirrors for in all likelihood the main section. you nevertheless have have been given to envision between the lines to get a evaluate for those applicants.
