A little bit of a nitpick, but wouldn't that be a picometer instead of angstrom node? Like, isn't a "pico-" the next magnitude smaller than "nano-", or am i wrong?

Otherwise, that chip tech sounds really awesome - at least for the future!

There are 3 orders of magnitude between nano (^-9) and pico (^-12). An Angstrom is ^-10m.

  • Useless fact I just learned from Wikipedia: Ångström/Angstrom (in Sweden of course we still use the original spelling) has its own UNICODE symbol, Angstrom sign: Å (U+212B) not to confuse with the Swedish letter Å (U+00C5). Looks slightly different in my browser.

    https://en.wikipedia.org/wiki/Angstrom

    • Looks like that's deprecated. From the next sentence:

      However, version 5 of the standard already deprecates that code point and has it normalized into the code for the Swedish letter U+00C5 Å `latin capital letter a with ring above`

  • Aaahhh, ok, thanks!

    • You had the right idea. Angstroms are not an SI unit. The SI units jump by three orders of magnitude at this scale: picometer, nanometer, micrometer, millimeter.

      (In the same way that meter jumps three orders of magnitude to kilometer[1], or millions to billions to trillions, etc.)

      [1] Technically there are intermediate SI units between meter and km but nobody uses them. There are not intermediate SI units between the tiny ones.

Because 1 angstrom equals 10⁻¹⁰ meters and 1 picometer equals 10⁻¹² meters, the relationship is:

1 Å = 100 pm. 1 pm = 0.01 Å.

1 picometer = 0.001 nanometers, 0.01 angstrom

1 angstrom = 0.1 nanometers, 100 picometers

1 nanometer = 10 angstroms, 1000 picometers
