Ernest Rutherford’s experiment was that he took a piece of gold foil and shot helium atoms at it. In theory they should have rebounded off of the gold foil because scientists at that time believed that the atom was a solid sphere‚ but what actually happened was that most of the atoms went through the gold foil.This showed that the atom wasn’t just a solid sphere like they believed but actually had a nucleus with electrons surrounding it. In 1897‚ a British physicist named J. J. Thomson discovered

The video “Nanospace: A voyage into ultra-microscopic worlds – Part 1: The atom revealed” is a fascinating story telling a brief history of nanoscience and scientists’ endless efforts to travel to the nanoworld. This inspiring video gives me a clearer imagination about the nanoworld‚ as well as several life lessons. I realized

The word atom is derived from the Greek word atom which means indivisible. The Greeks concluded that matter could be broken down into particles too small to be seen. These particles were called atoms. Atoms are composed of three types of particles: protons‚ neutrons‚ and electron. Protons and neutrons are responsible for most of the atomic mass. Example; if a person weighed 150 lbs. approximately 149 lbs. and 15 ounces of that person would be comprised of protons and neutrons while only 1 ounce of

of the Pre-Socratics‚ very little is known of Anaximander’s life. He was born‚ presumably in 610 BCE‚ in Ionia‚ the present day Turkish west coast‚ and lived in Miletus where he died in 546 BCE. He was of the Milesian school of thought and‚ while it is still debated among Pre-Socratic scholars‚ most assert that he was a student of Thales and agree that‚ at the very least‚ he was influenced by his theories. He is infamously known for writing a philosophical prose poem known as On Nature‚ of which
