NARRATOR: A simple pendulum can be made by attaching a bob or weight to one end of a light rod and then suspending the rod from the opposite end, so that it can swing freely and evenly from side to side. An everyday example of a pendulum can be seen in a grandfather clock. The pe...
The simple pendulum is one of the first experiments that students of higher physics do. There are certain precautions which the students are asked to take while performing the experiment. In this note we will try to explain as to why these precautions are taken up and what will happen if ...

Something that works this way is called a harmonic oscillator and its movement is an example of simple harmonic motion, though we won't go into those things here.Artwork: A pendulum is constantly swapping potential energy and kinetic energy....
Therefore, most seismographs involve a pendulum of some sort. You could make a very simple seismograph by hanging a large weight hanging from a rope over a table. By attaching a pen to the weight and taping a piece of paper to the table so that the pen attached to the weight can draw...
This process is way too complicated and unwieldy for a simple machine, and even by hand it only works well with short lengths of thread. Instead, modern sewing machines pass the needle only partway through the fabric. On a machine needle, the eye is right behind the sharp point, rather ...

Do we receive answers by magic? By spirits? By psychic powers? My preferred answer is that the dowsing pendulum works by connecting us to theunconscious mind, also known as theAkashic Records. When we ask a question, our unconscious mind responds by influencing the nerve endings in our finger...
