Pro Tip 1/3Safety Importance
Detectors often relate to safety, warning about dangers like smoke or carbon monoxide.
Every home should have a carbon monoxide detector for safety.
Pro Tip 2/3Specific Usage
Detectors are named for what they detect: smoke detectors for smoke, metal detectors for metal.
The airport security uses a metal detector to check for concealed weapons.
Pro Tip 3/3Detection Signals
Detectors usually signal their findings with lights, sounds, or digital messages.
The smoke detector beeped loudly when it sensed smoke in the room.

clearly the best chemical detector on the face of the planet. And you don't even think about it, do you? So this is a favorite quote of mine that takes us back to the ignorance and the idea of questions. I like to quote because I think dead people shouldn't be excluded from the conversation. And I also think it's important to realize that

This light spreads through IceCube, hitting some of its detectors located over a mile beneath the surface. Photomultiplier tubes amplify the signal, which contains information about the charged particles' paths and energies. The data are beamed to astrophysicists around the world who look at the patterns of light

But this happens on such a minute scale that we can't feel any of it. So we've built detectors that can feel it for us. That's what the LIGO detectors do. And they're not the only ones. There are gravitational wave detectors spread across the world.

Taylor Wilson
American Scientist
I've been focused on detecting nuclear terrorism at ports, in cargo containers, and I developed and built detectors that are extremely cheap and also very sensitive. My other big development is a system to produce medical isotopes that are injected into patients and used to diagnose and treat cancer.

Kids are smart: don't underestimate their bull detector. Contemporary kids have access to a lot of information, so don't even try to fool them. I have never been more nervous about my research than when writing for young adults because they pick up every single error.

Obama is the new kid with the weird name who people just sense is a little classier than his surroundings. He moved from a private school where he was class president and is now at the giant public high school with the metal detectors and the smoking lounge.

Security is a component of everyday life that one spending time in Washington, D.C., gets accustomed to. Metal detectors, police vehicle barriers and heavily-armed police officers become strangely commonplace after awhile.
