A mathematician, a physicist and an engineer are led into a long room. At the other end stands a beautiful naked woman. "When I ring this bell," she says" you may cross half the space between us. When I ring the bell again, you may again cross half the space between us." Both the mathematician and physicist groan and wander off. "Ah, it's Zeno's paradox, we can never actually reach her." The engineer, waiting for the bell, says "I think I can get close enough."

Also mathematicians: here's this cool new thing, I called it "infinitesimal"

In computer engineering we have positive and negative zero.

Limit x->0 { x } = 0 ? Noway

i mean, mathematically speaking, every number that isn't zero, is further away from zero, than the number before it.

So there is a point to the statement of "approaching zero" as well "near zero" and "about zero" since 100 probably isn't about zero.

Also CS nerds would like to fight you about floating point values.

sin(x) ~= 0

The infinitesimal has entered the chat.

lets ignore the higher order terms for now. five lines below look at this beautiful exact equality that we got

What about large values of zero?
