Radioactivity

Radioactivity is a property of element isotopes and heavy elements, such as radium, uranium, and plutonium. The atomic nuclei of these substances are unstable, so they decay by various means into more stable configurations. The three most common forms of radioactivity are alpha particles, beta particles, and gamma rays. Large doses of radiation can be quite harmful, so care must be used in handling radioactive materials.

Neuroscience: What is Brain Plasticity?

Neuroscience has changed considerably in the past 20 years. An example of change over period is the concept of brain plasticity. Brain plasticity refers to the brain's ability to rewire itself, relocating information processing functions to different brain areas and/or neural networks. Two decades ago, it was believed that brain networks were static after its initial formation period. Now that belief has changed. The study of brain plasticity has profound implications in human learning and behaviour, and as such, for mental health....

The Standard Model of Particle Interactions

The Standard Model of particle interactions is one of the most successful theories of all time. Devised between 1970 and 1973, this model incorporates everything that is known about particle interactions, including special relativity, quantum electrodynamics (QED), electroweak theory, quantum chromodynamics (QCD). The only thing left out of the theory is gravity.

String Theory-Science or Theology?

String theory, also known as superstring theory, is a dubious scientific theory which has received a lot of hype since the 1980s, when it showed promise toward being the much sought Unified Field Theory, or Theory of Everything, a theory which in principle is capable of explaining everything in physics. Unfortunately, after over 20 years, no one has been able to make a single experimentally verifiable prediction from string theory. Far from being the Theory of Everything, string theory thus far is a Theory of Nothing! Some have even gone so far as to say string theory is not science but theology, since it fails to make any testable predictions.

Lasers

Lasers are one of the marvels of 20th century science. Since their invention in 1960, lasers have come a long way. Now they're everywhere, from CD and DVD players to cashier check counters to laser light shows to industry and the military.

Biology - Characteristics of Insects - An Introduction

They range in size from microscopic soil-dwelling insects to large beetles and butterflies but they all share certain common features.

The High Pressure Steam Engine - Not Invented By James Watt

Richard Trevithick was born at Redruth in Cornwall on the 13th April 1771, the fifth child and only son of the manager of the Wheal Chance copper mine near Cambourne. Richard attended the local village school but more often than not he played truant, due to his poor attendance at school his head master said he was disobedient, inattentive and a time waster. He invented the high pressure steam engine.
