Lie detection technologies are not especially accurate; the polygraph test is the iconic method and is considered unreliable by the US National Academy of Sciences. It measures quantities like heart rate, which can fluctuate in response to stress. This stress may be the result of lying, or the result of taking a polygraph test, which is itself stressful. Other lie detection technologies exist, such as voice analysis, but no such method has been proven reliable.

Why do most thermometers use liquids?
Prior to semi-conductors, liquid was the practial way. Simple materials and construction. Accurate and reliable. Physics dont lie.
Why is it important for laser and radar guns to have regular calibration?
Law enforcement agencies regularly calibrate their radar guns to avoid disputes in court. Laser speed detection devices are actually so accurate that there is little need to calibrate them on a regular basis.

How do you tell when there are gases in mines?
Gas detection in mines has been around since the creation of mines, Today technology plays a huge part. There are sensor technologies designed to detect almost any gas to which we might be exposed. Some of these technologies include, but are not limited to, infrared and photo-ionization detection.

Why are scientists tempted to lie?
They aren't tempted to lie because if they lie and their research doesn't prove to accurate they are disgraced and their research is trash. They do everything possible to make sure what they do can be verified and proven.
Why 555 timer is used in fire detection?
A 555 timer is used in fire detection because it can take samples at regular intervals. This allows the mechanisms to accurate detect fires without a need to constantly strain the batteries.
