Note: In 1665, a young 23 year old Cambridge student decided not to fear the Great Plague of London that killed over 500,000 English people. Instead he stayed focused on education because he believed that education is the best weapon to defeat all evils. That paid off: the same year he invented calculus to lay the foundation of physics. I hope that this Coronavirus pandemic will create the next Sir Isaac Newton. ~ Rashidul Bari
