Test of Faith

Another must watch – this time by the Faraday Institute for Science and Religion. And for once, this accessible program is directed towards church groups and youth groups! There are even books and course materials for group discussions available with the DVD. If only I could get my hands on them!

Reflections in Cosmology 15: Where Have All the Energy Gone?

Imagine a cylinder filled with gas, pressurized by a piston. The kinetic energy (or thermal energy) of the gas particles exerts pressure on the piston, pushing it outward. As the volume in the cylinder increases, the gas particles lose energy and therefore cool down. Thermal energy has been converted into mechanical energy. Simple high school… Read More Reflections in Cosmology 15: Where Have All the Energy Gone?

Reflections in Cosmology 14: Misconceptions About Cosmic Expansion

The universe does not expand in space, instead it consists of expanding space. From this statement flows all the simplicity and complexity of modern cosmology. ~ Edward Harrison, Cosmology: The Science of the Universe Ever since Edwin Hubble published the famous results of his painstaking observations, we have come to realize that we are living… Read More Reflections in Cosmology 14: Misconceptions About Cosmic Expansion

Which Came First, the Dinosaur or the Bird?

Well… definitely the dinosaurs. In recent decades, the link between birds and dinosaurs have been strengthened through research into avian and dinosaur anatomy, together with the discovery of new feathered dinosaur fossils in China. It is now well established that many theoropods such as velociraptor and tyrannosaurus indeed had feathers. And it is thought that… Read More Which Came First, the Dinosaur or the Bird?

Reflections in Cosmology 13: An Interesting Thought on Black Holes

One of the most astonishing consequences of Einstein’s general relativity has got to be its prediction of black holes. Though undetectable directly, the observational evidence is so compelling that astronomers no longer doubt their existence. In fact, we’re convinced that monster black holes reside in the centres of all large galaxies, including our own –… Read More Reflections in Cosmology 13: An Interesting Thought on Black Holes
