Why is it not the foot that matters when an athlete is crossing the line? And which part of the body does it count? Is it the head or the chest?— Precedingunsigned comment added by137.205.24.140 (talk)03:08, 19 June 2007 (UTC)Reply
- It's the athelete's torso, between shoulders and waist. Otherwise someone could stick their arms out and shave a fraction of a second off their time.Neil ╦14:10, 12 July 2007 (UTC)Reply
- However, the arm itself doesn't count, only the shoulder, this is why you see athletes lunge forward, this is to ensure they gain an extra bit of distance, hence reducing their timeMrtechguy (talk)03:51, 23 November 2009 (UTC)Reply
In the cultural reference paragraph involving Futurama, there is some disagreement between whether the professor's statement is theobserver effect or theuncertainty principle. The uncertainty principle only states that it's impossible to know everything about a small particle (i.e. can't observe its location and momentum at the same time). The observer effect is about the act of observing something leading to a change in state - the action of observing something might alter the object observed. So, the professor's comment refers to the observer effect, not Heisenberg's uncertainty principle.Lisatwo01:30, 17 October 2007 (UTC)Reply

Because Photo Finish is a graphic editor (at least in 1990s). It allowed to enhance the photos, remove the white lines on them etc.83.239.180.230 (talk)18:22, 22 January 2011 (UTC)Reply

- That has an original filing date of December 15, 1947, so it's not among the earliest photo finish developments. In order to determine whether it was an important contribution to the history, we should have some discussion of it in independent reliable sources. — BarrelProof (talk)23:17, 2 August 2021 (UTC)Reply
