VIDEO : Queen Elizabeth Publishes First Instagram Post

Queen Elizabeth II made her first Instagram post.
On Thursday, the queen posted from the Science Museum to help promote the museum's summer exhibition.
Using an iPad, she shared an image of a letter from 19th century inventor and mathematician Charles Babbage to Queen Victoria and Prince Albert.
In the letter, Babbage told Queen Victoria and Prince Albert about his invention, the Analytical Engine, upon which the first computer programs were created by Ada Lovelace, a daughter of Lord Byron."
