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 الجهلاءُ،
وإذا رحمتَ فأنت أمٌ أو أبٌ
هذانَ في الدُنيا هما الرحماءُ
