The Physics of Superheroes is a popular science book by James Kakalios, a Physics professor at the School of Physics and Astronomy of the University of Minnesota, and a long-time comic-book fan. First published in 2005, the book explores the elementary laws of physics.
The Einstein Field Equations of General Relativity are vast and complex, but they can be written with deceptive simplicity.

The Open University has created a series of 6 short animated iTunes videos about the Philosophy behind Maths and Science.
The Open University has teamed up with “geek chic” comedian David Mitchell to release a series of 12 short animated YouTube videos about the Physics of the Cosmos: “60-Second Adventures in Astronomy”. A real treat. And it’s educational! If you have only 60 seconds, you can now learn everything we know about matter, energy, life, the Universe and everything…

The Standard Model of Particle Physics is a theory about the electromagnetic, weak and strong nuclear interactions, developed throughout the mid-to-late 20th century, as a worldwide collaborative effort. Upon experimental confirmation of the existence of quarks, the theory is finalised in the mid-1970s. Ever since that time, further evidence of its validity have been provided by successive discoveries of the other predicted particles, such as the bottom quark (1977), the top quark (1995), the tau neutrino (2000) and even more recently, the Higgs boson (2012) to complete the whole set.
The Earth has an electric field. On average, this field points vertically downwards and it has a magnitude of about 100 N C-1 (Newtons per Coulomb). It exists because the Earth’s surface carries a negative charge of – 5 x 105 C, while the upper atmosphere carries a compensating positive charge. An average of 400,000 thunderstorms a day sustain a relatively constant electric field.
