Could you, please, elaborate just a tiny bit. Try to explain:

• What application?
• What kind of field?
• What are you doing so far?

• My car is making a funny noise, can you tell me what it is?
• There's a problem with my house, can you tell me how to fix it?
• I'm having trouble understanding physics, can you explain it to me?
