    The concept was first developed by John D. Lawson in a classified 1955 paper [1] that was declassified and published in 1957. [2] As originally formulated, the Lawson criterion gives a minimum required value for the product of the plasma (electron) density n e and the " energy confinement time " τ E {\displaystyle \tau _{E}} that leads to net ...

  9. Fraction - Wikipedia

    en.wikipedia.org/wiki/Fraction

    Unit fractions can also be expressed using negative exponents, as in 21, which represents 1/2, and 22, which represents 1/(2 2) or 1/4. A dyadic fraction is a common fraction in which the denominator is a power of two, e.g. ⁠ 1 / 8 ⁠ = ⁠ 1 / 2 3 ⁠. In Unicode, precomposed fraction characters are in the Number Forms block.
