Every Sci-Fi Starship Ever, In One Mindblowing Comparison Chart

However, there is a small group of names that is split between male and female. The charts above show the most unisex names between 1930 and 2012.

Jessie, Marion, and Jackie top the list, as they’ve stuck around that 50-50 split over the decades. Of course, as you move down the list, there are more slopes up and down and some noisy spikes for the less common baby names, such as Gale and Alva.


Harvard plans to boldly go with ‘Spocs’

Harvard University is moving beyond massive open online courses (MOOCs) to small private online courses (SPOCs). Like MOOCs, SPOCs are offered for free over the Internet, but registration is limited to tens or maybe hundreds of students, rather than the tens of thousands that can enroll in a MOOC. SPOCs have a selection process for applicants and the ability to tailor the course experience. Fees and course credits for SPOCs could emerge in the future. However, Harvard will continue to offer MOOCs, along with SPOCs and traditional classroom-based courses. SPOCs will offer smaller class sizes that will increase student engagement and allow more thorough assessments, as well as the possibility of improved certification.
