Just found one of the missing scales from most publicized measurement scales. When they show us scales of measurement, after Nanometer (which its 10N is 10-9) there are two scales missing, up to 10-12 which is the Picometer scale. 10-10 is called the Angstrom size. So is a Yocto particle smaller than a nucleus. I mean smaller than our cells.. ??? -Sue Huelbig Size of the Nanoscale - National Nanotechnology Initiative nano.gov/...101/.../nano-si... U.S. National Nanotechnology Initiative A sheet of paper is about 100,000 nanometers thick; A strand of human DNA is 2.5 nanometers in diameter; There are 25,400,000 nanometers in one inch ... nano.gov/nanotech-101/what/nano-size Angstrom 10-10 m 0.0000000001 m 1/10,000,000,000 m ten billionth of a meter Some cells are visible to the unaided eye The smallest objects that the unaided human eye can see are about 0.1 mm long. That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification. A magnifying glass can help you to see them more clearly, but they will still look tiny. Smaller cells are easily visible under a light microscope. Its even possible to make out structures within the cell, such as the nucleus, mitochondria and chloroplasts. Light microscopes use a system of lenses to magnify an image. The power of a light microscope is limited by the wavelength of visible light, which is about 500 nm. The most powerful light microscopes can resolve bacteria but not viruses. To see anything smaller than 500 nm, you will need an electron microscope. Electron microscopes shoot a high-voltage beam of electrons onto or through an object, which deflects and absorbs some of the electrons. Resolution is still limited by the wavelength of the electron beam, but this wavelength is much smaller than that of visible light. The most powerful electron microscopes can resolve molecules and even individual atoms. learn.genetics.utah.edu/content/cells/scale/ Angstrom size particles: https://google/search?q=Angstrom+size+particles&oq=Angstrom+size+particles&aqs=chrome..69i57.992j0j9&sourceid=chrome&es_sm=93&ie=UTF-8 [PDF] Aerosol climatology: dependence of the Angstrom exponent ... ://atmos-chem-phys-discuss.net/.../acpd-7-7347-2007...... by DG Kaskaoutis - 2007 - Cited by 62 - Related articles May 30, 2007 - The ˚Angström exponent, α, is often used as a qualitative indicator of aerosol .... particle size or fine mode fraction (Kaufman et al., 1994). The answer to Sues question would be yes. And thats a scientific fact.
