Remembering femtochemistry founder, Ahmed Zewail, who was born on this day in 1946.
In the late 1980s Nobel Prize laureate Zewail developed methods for studying chemical reactions in detail. 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.
By using laser technology to produce flashes of light just a few femtoseconds long, Zewail was able to visualise these reactions in slow motion - and to see what actually happens when chemical bonds break and new ones are created.
