It has been eight amazing weeks for DART of Physics. We've loved talking to...

Our event in Pearse Street station last week, discussing physics with commuters, was a lot of fun! The Trinity College news page writes more:
Trinity undergraduates and postgraduates performed a series of eye-catching demonstrations at Pearse Street station. Each demo showcased physics in just one to two minutes, thereby making it accessible to people waiting to catch their trains.
In addition, commuters were met by students wearing brightly coloured ‘DARTofPhysics... Continue reading
Revolutionary technology has resulted from visionaries and entrepreneurs who have “thought big.” However, in the case of antimicrobial and self-cleaning technologies, reducing materials size to the nanoscale can reduce the cost and maintenance of our transportation system.
Nanomaterials are any materials that are 1-100 nm in one dimension, which means they have properties that depend on their size. These materials can have special properties, which are different from their bulk counterparts. For example, cadmium selenide quantum dots can absorb different wavelengths of light between...

RTÉ's Morning Edition had a segment yesterday on DART of Physics doing demonstrations and an iPad giveaway in Pearse Street Station! You can watch it here, with the interview with Prof. Shane Bergin and discussions with TCD physics undergraduates beginning at 1:07. See Laura and Maurese explain why they love physics and how a van de Graaf generator works!
You've probably heard of a plasma display, and may even know that a plasma is a phase of matter, like a solid, liquid, or gas. But what does that mean? What's a plasma and how is it used in displays?
Plasmas are usually considered a state of matter. But whereas order and density distinguish the other states of matter from each other—solids are dense and ordered, liquid are dense and disordered, and gases are less dense and disordered—for plasma there is another factor that is important. Plasmas are disperse and disordered like gases, but they are also ionized. Whereas a non-ionized... Continue reading
DART of Physics' own Jessamyn Fairfield, who has been writing and editing the blog during the DART of Physics campaign, has just received an award from the Institute of Physics in London for her science writing work. The Early Career Physics Communicator Award is given annually to people at the start of their careers in physics who have undertaken activities that support and encourage excellent communication of physics. From the... Continue reading
Over the weekend, people around the world have been following the progress of Comet ISON as it passed close by the Sun. The 2-mile radius comet was discovered last year, and has been steadily brightening as it approached perihelion, coming within two solar radii of the Sun itself. We talked about SOHO, the Solar and Heliospheric Observatory, back in Jason Byrne's guest post on the Sun, and they have some amazing images available of the comet's... Continue reading
