The passage around this formula

…systematic uncertainties of a few hundredths, and stated that the data indicated a nonzero, positive cosmological constant at 99 percent confidence [ 3 ] . That result places the implied vacuum energy density at roughly ΩΛ\Omega_\Lambda ≈\approx 0.7 — a value sitting comfortably inside the “quite large” anthropic window Weinberg had described eleven years earlier, and specifically within the one-to-two-order-of-magnitude band he had flagged as anthropically interesting.
