May 21, 1932: Amelia Earhart Breaks Records

On this day in 1932, Amelia Earhart became the first woman to fly solo across the Atlantic Ocean. She departed from Newfoundland and landed in a pasture in Northern Ireland.

Amelia Earhart may have been the most well-known woman pilot of her time, but she was neither the first nor the last to achieve great heights in the world of American Aviation. Check out American Experience’s “Women in Flight” photo gallery for more.

Today, the Center of Math has a special blog post and infographic about women in STEM to honor all of their amazing accomplishments. While the number of women in math and other STEM disciplines today is still small compared to the amount of men, it is important to realize that women can achieve just as much as men can, because gender does not determine intelligence, skill, or aptitude. We hope this graphic, as well as the blog post, inspires all of you!

You can view this infographic, along with a brief bio about each of the ladies, by visiting this link to our blog.

1977. East German ,,Pionierpanzer” operated by Young Pioneers (Jungpioniere), a suborganisation of the Ernst Thälmann Pioneer Organisation. Sections provided with these mini-tanks were effectively called ,,Panzerbrigade” (Armoured Brigade), which apparently operated under STASI supervision.

These ,,Pionierpanzer” were powered by a Trabant engine and had a top speed of 15 kph. The turrets couldn’t traverse. The crew was composed of 2 Jungpioniere. Different models were in production, resembling actual tanks: T-34-76, T-34-85. T-54, SU-100, and SU-122.

Sources are contradictory regarding the guns: some claim they could fire live ammunition, some that they could fire only blanks, others that “hits” were scored using a laser system, similar to nowaday’s Laser Tag.

Existing footage confirms that they were at least capable of firing blanks.

“I failed on a climbing problem eight times before realizing I was climbing as high as I knew I could and then letting go. On my next try I climbed with no thought of failure and reached the top. We cannot know what we can do in advance. The only way to find out is to go all-out trying, thinking only of success.” -Royal Robbins 

“No historian of today would dare to claim a supreme indifference to geography. Man cannot go entirely beyond his physical environment, either biologically or socially. The effect of climate on the physical, mental, and moral condition of individuals is everywhere admitted.” - Zonia Baber, “The Scope of Geography,“ 1904.

This is a woman you should know! 120 years ago, UChicago student, Zonia Baber (1862-1955), was gathering fossils at Mazon Creek, Illinois. Zonia was enrolled in a summer class in geology, taught by Thomas C. Chamberlin. This was the first field class at the University of Chicago to which women were admitted.

Zonia went on to be a pioneer in geography education. She founded the Geographic Society of Chicago in 1898, and was head of UChicago’s geology and geography department from 1901 to 1921.
