Estimates Memes

In the wild habitat of construction sites, two engineers engage in their natural behavior: rounding numbers until they're practically unrecognizable. One engineer shows a measurement of "70" and the other responds with "Nice" – not because it's actually nice, but because it's close enough to work and they can go home early. In engineering, π = 3, e = 3, and sin(x) = x when it's Friday afternoon. The building might lean slightly, but hey, that's why we have safety factors of 10.
