What do you think about when you think about the 20th century? Maybe you think of cars and airplanes, Neil Armstrong walking on the moon, or just the old pictures of your parents you see around the house.
In fact, the growth of industry and technology define the 20th century. From the first wobbly airplanes to high-speed jets, and from early horseless carriages to the modern sports car, the 20th century was all about progress. California played an important role in that progress. It still does. Oil, automobiles, and aviation – the science of flight – helped transform California into the thriving modern state it is today.
