Chemical reactions in which molecules held together by atoms meet and reorganise into new compounds are one of nature's most fundamental processes.
 
However this transition happens too quickly for us to easily see - in a matter of femtoseconds. One femtosecond is 0.000000000000001 seconds, which is to a second as a second is to 32 million years.
 
In the late 1980s Nobel Laureate Ahmed Zewail developed methods for studying chemical reactions in detail. By using laser technology to produce flashes of light just a few femtoseconds long, he was able to visualise these reactions in slow motion - and to see what actually happens when chemical bonds break and new ones are created.
