HOW TO CATCH A LION

Newton's Method : 

Let lion catch you. For every action there is an equal and opposite reaction. This implies you have caught the lion (Assuming that you're alive). 

Einstein Method : 

Run in the direction opposite to that of the lion. Due to higher relative velocity, the lion will also run faster and will get tired soon. Now you can trap it easily. 

Inverse Transformation Method : 

We place a spherical cage in the forest and enter it. Perform an inverse transformation with respect to lion Lion's in and we are out! 

Thermodynamic Procedure : 

We construct a semi-permeable membrane which allows every thing to pass in it except the lions. Then sweep the entire forest with it.

Integration Differentiation Method : 

Integrate the forest over the entire the area. The lion is somewhere in the result. So differentiate the result PARTIALLY w.r.t. the lion to trace out the lion. 

Bohr Method : 

Find a lioness. The lion would be rotating around her in circular paths, and eventually would decrease the radius between him and his nucleus.
