Cách sử dụng
The expression "in a vacuum" means that something is being considered or observed without taking into account the larger context or factors that might influence it. It is often used to describe situations or scenarios where there aren't any outside influences or factors that could impact the outcome. For example, if you were testing a new product in a laboratory environment, you might say that you were testing it "in a vacuum" because you are only looking at how the product performs in that specific setting, and not taking into account how it might perform in the real world.
