And now its protected and shaded from light. Can you cover all the rational numbers in that period, from light, with a line segment(s) that is less than 1 (total)? How? (You can use multiple segments, with or without overlaps, light rays are perpendicular to the number line)
Imagine a number line (labeled with integers). Then imagine that the Rational numbers are light-sensitive. Your goal is to protect all the rational numbers in the period [0, 1] from sun-light. If you have a line segment — with length 1, you can cover the period [0, 1] completely.
فإذا سخوتَ بلغتَ بالجودِ المدى
وفعلت ما لا تفعل الأنواءُ،
وإذا أخذتَ العهد أو أعطيتهُ
فجميع عهدكَ ذمةٌ ووفاءُ
وإذا عفوتَ فقادرًا ومقدَّرًا
لا يستهينُ بعفوكَ ال��هلاءُ،
وإذا رحمتَ فأنت أمٌ أو أبٌ
هذانَ في الدُنيا هما الرحماءُ
