    The periodic table turns 150 years old this month. The United Nations General Assembly and UNESCO have dubbed 2019 the International Year of the Periodic Table of Elements (IYPT2019).

    As a chemical engineer, you might not use the periodic table very often (if at all), but you may have started your studies in chemistry learning about the period table. What were some of your experiences learning about the periodic table and chemistry?

    The periodic table is one of the great human achievements, often overlooked on such lists.  It took millennia of accumulated  knowledge to crystallize the organization and properties of materials into the an exactitude of thought which is the periodic table we often take for granted. 
    It's simple beauty eluded the greatest minds in history.....Chaucer, Newton, Lavoisier and many others until Dobereiners triads. 
    Is it even possible to imagine the perception of material objects we would have held pre-periodic table?

    There is a terrific article about the Periodic Table and its history in, of all places, The Economist, Feb 28 edition. It's worth a look:

    Yes, quite so, thank you for the recommendation. Have not read yet but I noticed that it starts by mentioning Lavoisier's beheading. He was a true scientist to the end. At the time there was discussion as to how long one remained  conscious after decapitation. He made an arrangement with a friend to blink and continue to blink until he lost consciousness and requested that his friend count the number of blinks so as to know how long he remained conscious after his head was raised for the crowd to view. I think he got up to 8.

    So, 1869.  That was the start of a tremendous spurt of economic growth and productivity, according to The Rise and Fall of American Growth, by Robert J. Gordon. 

    What I learned and valued the most: elements grouped in columns have similar properties due to having the same number of valence electrons.
