Truth and Lie, how to tell the difference

How do you know if someone is telling you the truth. How do you know if someone is telling you a lie. Is there a physical way to find out?

I figured this one out based on numeroloy - gematria. How? The gematria of Truth or Emes in Hebrew is 441. The gematria of a lie or false aka sheker is 600. The difference between the truth and a lie is 159. Another phase with 159 is katan, or small. Hence, the devil is in the details. You can tell someone is telling you the truth by the small little details he/she tells you. Or if you question someone, the minute details will let you know if this person is truthful or not.
