Wisely Not Putting One and One Together.
Happy Birthday to ha_chan! According to Wikipedia, your birthday falls on the day in 1868 that an astronomer, Pierre Janssen, looking at a spectral graph of the chromosphere of the sun, saw a bright yellow line at 587.49 nanometers. At first, he assumed the line to be sodium. However, what he had actually run into was the first evidence of the existence of an important element: helium. It's also the day in 1920 that women in the United States had been looking forward to for a long time. On that day, Tennessee became the 36th state to ratify the 19th Amendment to the constitution, granting women the right to vote. Tennessee's ratification officially ratified the amendment for the United States. Hope you have a wonderful day today!
