This is a Learn British English Free lesson in which Chris explains the difference between “look for” and “search (for)”.
Look for – more natural, common and informal (always with “for”)
“I can’t find my car keys.” “Let’s look for them then”.
“What are you looking for?”
Search (for) – more formal (e.g. police)
“The police are urgently searching for the suspect.”
“The police were searching the area last night.” (verb without “for”)
“The police conducted a thorough search of the property.” (noun)
“…The Non-Member State Summer Student Programme represents a unique opportunity for students from around the world, especially from less advantaged countries, to spend their next summer getting involved in some of the world’s biggest scientific experiments at CERN. For most of the students, their summer at CERN will represent a lot of firsts. The first time they will travel abroad, the first time they will work in a fully-equipped physics laboratory, the first time they will meet fellow students from different cultural backgrounds.”
Imagine an archer who has shot ten arrows. In this scenario, precision is a measurement of the arrows’ positions relative to each other and accuracy is a measurement of their positions relative to the bullseye. A precise archer isn’t necessarily an accurate one, and vice versa.
The precision of an archer is analogous to a concept called clock stability. If one thinks of each tick of the clock as a shot and hitting the bullseye as keeping the exact right time between every tick, then a precise but not accurate clock would consistently tick either slower or faster than the desired amount of time. On the other hand, an accurate but imprecise clock would tick sometimes faster and sometimes slower, but the accumulated errors would average out somewhat over time.
