Length shifting - NanoMeters in your hands (original) (raw)
| Nanometers in your hands 10-9 meters per mm (Magnification of ×106) | **10 [ -6 | -3 | 0 | 3 | 6 | 9 | 12 | 15 | 18 ]** If bacteria were beachballs... 10-6 meters per meter |

Doables: Flesh out. Nanocrystals (grain sizes ~ 1-10 nm) are a delightful intermediate between atomic and bulk behavior. Lysosomes/microbodies vary in size from 0.2 to 2 um. phospholipid bilayer, miscelle bacterial memb/wall crosssection. viral spikes (herpes, 100nm isoc) are 10nm long SET wire ~16nm, dot ~12.
Notes: Digitized Electron Micrographs The ball-like animal viruses from Electron Micrographs of Animal Viruses. The stick-like plant viruses from Electron Micrographs of Plant Viruses: Tobacco Mosaic Virus x300,000 RNA, non-enveloped, monopartite Barley Stripe Virus x300,000 RNA, non-enveloped, tripartite Maize Mosaic Virus x150,000 RNA, enveloped (bottom tubular) Maize Streak Virus x300,000 DNA, non-enveloped (tiny double puffball) 150 dpi 9.5 x 7.5" (0.2413 x 0.1905 m) 150 dpi 0.00666"/dot 1.693x10^-4 m/dot x3e5 0.6 x10^-9 m/dot 100nm = 167 dots (Thus dot is how many atoms? :) Shrunk by x2 to match animal viruses. I wonder if they have the mag quite right on the Maize Streak - it seems small...
Should redo screen w 72 dpi? Typical screen's 75 dpi(?) is 3.387e-4 m/dot ie 0.3387 mm/dot Typical screen "real" scale: 0.3387 mm/dot 0.3387 nm/dot 10 nm = 29 dots, 100 nm = 295 dots
Viral 100 nm bar is 73 dots, so 1.4 nm/dot
Calling atoms 10-9 m is pushing it, as many fall below the 3.16 Angstrom threshold down into order 10-10.
Nanophase materials[link broken] have 1-100 nm grain sizes.
Retroviruses are 80 to 130 nm. Carbon nanotubules are a few nm in diameter and many um long. (Nature 98 Jan 28 p466) An ATP synthase (proton pumping <-> ATP) with spinning rotor 10nm diameter and about 20nm high. (Nature 98 Jan 28 p510).
History: 2003-Feb-03 Repaired links - 3 fixed, 1 flagged, 1 left (bocklabs). 2001.Apr.20 Added link to `How Big Are Things?'. 1998.Jun.17 Corrected error with magnitude boundaries (3.333->3.162). 1997.Oct.07 Added LDL. 1997.Aug.19 Removed some viruses to speed loading.
