danielrapp.github Recently I stumbled upon an interesting paper for implementing motion sensing requiring no special hardware, only a speaker and mic! Unfortunately the paper didn't include code to test it, so I decided to reproduce it here on the web! What is the doppler effect? First of all, what is the doppler effect? The doppler effect is a physical phenomenom which affects waves in motion.

Timelines The story of vaccines did not begin with the first vaccine–Edward Jenner’s use of material from cowpox pustules to provide protection against smallpox. Rather, it begins with the long history of infectious disease in humans, and in particular, with early uses of smallpox material to provide immunity to that disease. Evidence exists that the Chinese employed smallpox inoculation (or variolation, as such use of smallpox material was called) as early as 1000 CE. It was practiced in Africa and Turkey as well, before it spread to Europe and the Americas. Edward Jenner’s innovations, begun with his successful 1796 use of cowpox material to create immunity to smallpox, quickly made the practice widespread. His method underwent medical and technological changes over the next 200 years, and eventually resulted in the eradication of smallpox.
Most Popular Artists The most popular artist searches last month: a not-to-be-taken-too-seriously measurement of which famous artists have the greatest "mindshare" in our collective culture. Moving up: Edgar Degas (#22 to #12), Titian (#28 to #18), and realist painter Janet Fish (appearing for the first time on the list at #29). Moving down: Joan Miro (#13 to #19), Wassily Kandinsky (#11 to #24) and Paul Gauguin (#21 down to #32). Fine art Fine art, from the 17th century on, has meant art forms developed primarily for aesthetics, distinguishing them from applied arts that also have to serve some practical function. Historically, the 5 main fine arts were painting, sculpture, architecture, music and poetry, with performing arts including theater and dance. Today, the fine arts commonly include additional forms, such as film, photography, conceptual art, and printmaking. However, in some institutes of learning or in museums, fine art and frequently the term fine arts (pl.) as well, are associated exclusively with visual art forms.
Cell Models For life all cells have basic needs. Cells have diverged in their structure and function to accommodate these survival requirements. Here are some KEY TERMS to help you think, explore and search for similarities and significant differences that have become the characteristics of eukaryote (animal, plant) and prokaryotic (bacteria) cells. Examples might be searching: eukaryote prokaryote reproduction or animal plant cell energy. Reproduction / cell division Energy trapping, storage and consumption Form / shape / structure Cell specialization Compartmentalization of cell functions Communication within and beyond the cell Cell / organism survival Making of America aking of America (MoA) is a digital library of primary sources in American social history from the antebellum period through reconstruction. The collection is particularly strong in the subject areas of education, psychology, American history, sociology, religion, and science and technology. The collection currently contains approximately 10,000 books and 50,000 journal articles with 19th century imprints.

Seeing that boulder you think it should come crashing down the mountainside. It’s out of balance and you feel the tension of the impending crash. A similar feeling happens in your visitors when the composition of your design is visually out of balance. In a couple of previous posts I talked about visual balance and in each I briefly mentioned the idea of visual weight in order to achieve visual balance.
