Physics Girl
Season 2015
Physics Girl is a resource for fun physics videos and other materials about physics and topics related to physics. Initially started as a post-baccalaureate "not sure what I'm supposed to do with my life" project, it has grown into a resource for teachers, a source of entertainment for physics nerds, and a way for me to share a passion for physics while advocating for women in the sciences. If you have an idea for a fun physics video, feel free to contact Physics Girl.

- Special Relativity and the Twin ParadoxE4
Special Relativity and the Twin ParadoxHow can just two rules of Einstein's 1905 theory of special relativity lead to seemingly paradoxical changes in the perception of time? This video was inspired by a special relativity class in high school. Special relativity was one of the first subjects that made me go, “wow, that’s really how the world works?!” It stretched my imagination, as I hope the twin paradox will yours. - New Horizons first probe to reach pluto!E8
New Horizons first probe to reach pluto!The New Horizons probe reached its closest approach to Pluto on July 14, 2015 at 7:49 EST. We have received more and more detailed images and data about the dwarf planet and its largest moon, Charon. Very exciting times! - How to Make a Cloud in Your MouthE10
How to Make a Cloud in Your MouthLearn how to make a wispy cloud come out of your mouth, even when it’s not cold out. Like any awesome trick, physics is to thank for the mouth cloud. This simple and fun demonstration can be used to explain the cloud in a bottle experiment, and real clouds in the sky. - Can you take perfect 3D photos?E11
Can you take perfect 3D photos?3D movies and TV are is increasing in popularity, but is any of it truly 3D? How true is the 3D in movie theaters? How do glassess-less 3D TVs work? Try catching a ball with one eye closed. If you find it easy, try having the ball thrown a couple of feet in front of you, or from further away. It becomes increasingly difficult when the throw is off. - How 3D holograms workE12
How 3D holograms workHolograms are photographic recordings of 3D scenes. Unlike a camera, which captures one view through a small viewer focused by a lens, holograms capture an entire light field which allows them to recreate the 3D scene. Shimmery 2D projections, like pre-recorded Pepper’s ghost illusion, are often confused with 3D holograms. - Epic Space Rescues ft. BrainCraftE13
Epic Space Rescues ft. BrainCraftIn The Martian, astronaut Mark Watney is stranded alone on Mars and must be rescued. It is an exciting tale of what could happen once humans start traveling to the red planet. Let’s take a look back at the most epic space rescues in history. - Are MRIs safe?E18
Are MRIs safe?Are there any dangers associated with receiving an MRI and how exactly does an MRI work? Is it safe? Medical imaging, specifically magnetic resonance imaging (MRI), has come so far that we can create high resolution images of the entire body. The technology utilizes a cylindrical cavity surrounded by a giant electromagnet, and the magnetic field though the cavity is used to image body tissue. - Are perpetual motion machines possible?E19
Are perpetual motion machines possible?A wheel that spins forever; a bird that never quenches its thirst; a clock that never stops ticking, an endless source of free energy. These are but the dreams of inventors striving to make perpetual motion machines, machines that can work forever without any energy input. Are these machines possible without violating the laws of physics? No.
