Post-reading E=mc2 “A small piece of mass could produce an unbelievable amount of energy.” “Man is but a reed, the most feeble thing in nature, but he is a thinking reed.”(Pascal) 人只不过是一根苇草，是自然界最脆弱的东西；但他是一根能思想的苇草。(帕斯卡尔) Post-reading Homework Search online to find more major discoveries and inventions of the 21st century and give a short presentation of them in the next class. Virtual reality, or VR, has brought scenarios once seen in the field of science fiction, into real life. Using VR goggles, users can be transported anywhere to experience whatever they want. VR can  be widely used in artificial intelligence, education and training,  medicine, gaming and tourism. It’s the most important invent, I think. But I also feared the potential risk of some people choosing to spend most of their time in this fantasy world to escape their humdrum existence and real human  contact.
