Another Independence Day is in the books, and for many of us in the U.S. it included spending time with friends, family, food and the traditional holiday fireworks. Around the world, fireworks add to the enjoyment of many annual celebrations and events. Their colorful visual and audio display has the ability to thrill us, no matter what age we are. Despite growing older I never seem to tire of fireworks; I’ve also noticed that with each passing year the show seems to get more sophisticated. Whether it be a new color or shape or design of firework, pyrotechnic technology seems to improve at an impressive rate.
That got me thinking… how do fireworks actually “work”? Basic chemistry and physics are clearly at play, so in the spirit of a science-related blog I decided to look into this and share what I’ve learned. Continue reading “The Science of Fireworks”
Science is all around us— in everything we touch, smell, taste and see. It is in the flowers in our gardens, the molecules of pollen and oils that give those flowers scent, the crystals of sodium chloride that gives our food flavor and the way light is bent and changed to give our world color. There is science in the way we look like our great-great grandmother, and science in the way we are so different from each other. As the granddaughter of a forester and a botanist and the daughter of a science teacher, there has been science in my life for as long as I can remember. Recently my parents moved to a retirement home, and as I spent time helping them downsize, I took pictures of some of the ‘science’ that surrounded my as I grew up.
When Dave Romanin came to work for Promega he was fresh out of school with a degree in bacteriology. His plan was to work for a year in manufacturing and then go back to graduate school. But in the end, he didn’t go. There was no incentive, he explains, for him to spend five years in graduate school making little to no money. He didn’t want to write grants or run his own lab, and he enjoyed what he was doing.
