"Frickin' Sharks with Frickin' Lasers" As a laser engineer, I have to endure what that movie has done to that field at least once a month, and without fail on every plane ride. But many people simply do not understand, from either a theoretical or...
History of the Geiger counter
By: Srikanth Radhakrishna
Nuclear radiation can cause significant harm to living beings. It cannot be detected by human senses. Instruments are used to detect radioactive emissions. Geiger counter is one such instrument. Also known as Geiger-Müller counter, this particle detector is used extensively to detect nuclear radiation...
History of the Geiger counter
By: Jose Juan Gutierrez
A Geiger counter, also known as Geiger Muller counter, is a detector of nuclear particles that is used for measuring ionizing radiation. A Geiger counter is utilized to detect emitted radiation of gamma rays, X-rays, beta particles and alpha particles. A Geiger counter detects radiation...

With the ever-growing risk of nuclear disasters and threat of radioactive material being released into the environment, detecting its presence is vital for any intervention or research activity. The Geiger counter is a device developed for this exact purpose and the scientists Hans Geiger and...
Introduction to the dye-sensitized solar cell (DSSC)
By: Alexius Tan
Introduction to the dye-sensitized solar cell. As the name suggests, it is a type of solar cell that is “sensitized” by a dye. What does this actually mean? Before further confusion occurs with the emergence of more scientific terms, some simple theory of electricity...
