Newton Laws for Softwarez

Law 1 ..Every Software Engineer continues his state of chatting or forwarding mails unless he is assigned work by manager.

Law 2. The rate of change in the software is directly proportional to the payment received from client and takes place at the quick rate as when deadline force is applied.

Law 3. For every Use Case Manifestation there is an equal but opposite Software Implementation. Bonus :-)

Law 4 .. Bugs can neither be created nor be removed from software by a developer. It can only be converted from one form to another. The total number of bugs in the software always remains constant.
