Measuring the speed of light using a microwave oven

Most of us are aware that the light has a speed. Therefore scientists have done experiments and finally came into a single numerical number which describes the speed of light. In fact it is 299 792 458 m / s which is around 3 x 10^8 m/s. But have you ever thought how you could get this value by experiments?
In this post I will be explaining you on how to do this using a microwave oven which is used in your kitchen for preparing food in day to day life.

Genetically modified plants used to detect landmines

       This is actually a scientific research or experiment carried by some Danish scientists in Aresa biotechnology.They have done experiments on this particular plant for more than one year and they have finally reached for the success.They have showed this particular genetically modified plant can detect three different types of landmines.

Lie detecting by observing eye movements

This is a continuation of my before post >>>  A little about the techniques used to detect liars
As i promised to write you about the relationship between eye movements and lie detecting, I'm here to write you about it......
