Agriculture science began in 1700s, and involved scientists who applied the natural sciences to agriculture. Today, science helps to develop better crops and livestock, improved management systems and new ways to use agricultural products. The Industrial Revolution caused widespread changes to the western world. Improved farm machinery and agricultural techniques boosted food production needed to feed the burgeoning city populations. Many people left the land to work in the new factories.
Modern scientists use sophisticated instruments and computers.
Advanced technology permits a large number of increasingly detailed analyses. Computers linked to instruments receive the initial data, do the complex calculations and display output on video screens, or as printed output. He is called the father of microbiology because he was the first to make detailed written and illustrated observations on microscopic life. He was the first person to describe blood cells, bacteria and protozoa. The seed drill, invented by Jethro Tull, was the first agricultural machine.
