To celebrate WebAssign’s 15th anniversary, each Monday we will be bringing you 15 anniversaries in science, technology, mathematics, and education that you can look forward to throughout the week. Here are some important dates in history coming up this week:
1925 – American physician Baruch Samuel Blumberg is born. Blumberg develops a screening test for the cancer-causing virus hepatitis B, and later develops a vaccine for the virus. Blumberg freely distributes the patent for the vaccine, resulting in its wide administration and a reduction in infection rates of hepatitis B in Chinese children from 15% to 1% within a decade. Blumberg later receives the nobel prize for his work researching the prion disease kuru.
1898 – American physicist Isidor Isaac Rabi is born. Rabi receives the Nobel prize for his discovery of nuclear magnetic resonance, the phenomenon utilized by magnetic resonance imaging (MRI). Rabi later uses the newly-discovered cavity magnetron to improve radar technology. This work later becomes integral in the development of the microwave oven.
2005 – Astronomers from Palomar Observatory announce the discovery of the dwarf planet Eris. The trans-Neptunian object is also classified as a plutoid, and is about 25% more massive than Pluto, while being approximately the same size.
1889 – Russian physicist Vladimir K. Zworykin is born. Zworykin developed a method of transmitting and receiving television images using cathode ray tubes, and was greatly involved in the early development of the television.
1947 – French virologist Françoise Barré-Sinoussi is born. Barré-Sinoussi receives the Nobel prize for her discovery of the human immunodeficiency virus (HIV), the virus which causes acquired immunodeficiency syndrome (AIDS).
1885 – Hungarian chemist George de Hevesy is born. Hevesy discovers the element hafnium, and receives the Nobel prize for his development of radioactive tracers used in scientific research to study certain chemical processes in organisms, and used in medicine for procedures such as PET scans.
1820 – Irish physicist John Tyndall is born. Tyndall is the first to prove that the earth’s atmosphere exhibits a greenhouse effect. In addition to inventing an improved respirator for firemen, and an improved foghorn, Tyndall publishes seventeen books to educate the public about experimental physics.
