GPS 這個隨處可見的技術沒有相對論，根本無法準確定位，而手機與物聯網的功能將非常有限。
Without Einstein’s theory of relativity, GPS can not provide accurate location positioning at all. while mobile phones and the Internet of Things would pose very limited capabilities.

「雙生子悖論」可說是相對論中最著名的想像實驗，愛因斯坦的「同時相對性」改變了人類根深蒂固的「絕對同時性」觀念。
The Twin Paradox is the most famous thought experiment in relativity. Einstein’s theory of relative simultaneity has changed the deep-rooted notion of absolute simultaneity.
