Hi there! My username here is Rosalina2427. I went on Wikipedia for the first time around 2008, but I didn't become a registered user until 2010. In the beginning of my Wikipedia life, I went around hurricane talk pages, constantly forgetting the fact that Wikipedia is not a forum. I was also young, inexperienced, and absolutely naive about Wikipedia itself as an exceptionally annoying WikiKitten. After being warned a few times by more experienced (and extremely exasperated) users, I found my footing and became, well, more experienced and mature on Wikipedia.

Nowadays, I go around undoing vandalism, copyediting, updating tropical cyclone information, and checking out the Teahouse at times when I can squeeze it in to help and guide new users who are just like me back in the day.

Picture of the day

Luis Walter Alvarez (1911–1988) was an American experimental physicist who was awarded the Nobel Prize in Physics in 1968 for his discovery of resonance states in particle physics using the hydrogen bubble chamber. After receiving his PhD from the University of Chicago in 1936, Alvarez went to work for Ernest Lawrence at the Radiation Laboratory at the University of California, Berkeley. He joined MIT Radiation Laboratory in 1940, where he contributed to a number of World War II radar projects and worked as a test pilot, before joining Robert Oppenheimer on the Manhattan Project in 1943. He moved back to Berkeley as a full professor after the war, going on to use his knowledge in work on improving particle accelerators. This 1969 photograph shows Alvarez with a magnetic monopole detector at Berkeley.Photograph credit: Lawrence Berkeley National Laboratory / Department of Energy
