The concept of linguistic relativity, also known as the Sapir-Whorf hypothesis, proposes that the language we speak influences the way we perceive and think about the world. Different languages may shape cognitive processes, affecting how individuals categorize and interpret their experiences. While the extent of linguistic relativity remains a topic of debate, its influence on thought patterns is evident in various linguistic communities.

Q.1: What is linguistic relativity?
Q.2: What does linguistic relativity influence in individuals?

The concept of time dilation, a phenomenon predicted by Einstein's theory of relativity, suggests that time can pass at different rates depending on the gravitational field and velocity. As an object approaches the speed of light, time for that object appears to slow down relative to an observer in a different frame of reference. This theory has been experimentally verified with atomic clocks on high-speed jets.

Q.1: What does Einstein's theory of relativity propose regarding time?
Q.2: How has time dilation been experimentally verified?
