If we knew what it was we were doing, it would not be called research, would it? - Albert Einstein.   One accurate measurement is worth a thousand expert opinions - Grace Hopper.   Make a habit of two things: to help; or at least to do no harm - Hippocrates.   The threat is the virus, not the people. - UN Human Rights, Office of the High Commissioner.   In these unprecedented and uncertain times we must get used to the new normal, which is important, now more than ever.
