By: Robin Fearon Hydrogen gas is the most abundant element in the universe. It is an odorless, non-toxic, non-corrosive gas that burns easily in air to produce a large amount of heat, zero greenhouse gases, and water pure enough to drink as a by-product. The ‘hydrogen economy’ is seen by many as a natural replacement […]

By: Robin Fearon Oxygen, hydrogen, carbon, and a few other elements from the periodic table make up 99% of our bodies. October 08, 2020 Our body’s chemical and physical make-up and the way it functions are incredibly complex. Human bodies are estimated to contain up to one hundred trillion cells. We need fuel for these […]

Until recently, astronomers estimated that the Big Bang occurred between 12 and 14 billion years ago. To put this in perspective, the Solar System is thought to be 4.5 billion years old and humans have existed as a genus for only a few million years. Astronomers estimate the age of the universe in two ways: […]

Planet Earth doesn’t have a birth certificate to record its formation, which means scientists spent hundreds of years struggling to determine the age of the planet. So, just how old is Earth? By dating the rocks in Earth’s ever-changing crust, as well as the rocks in Earth’s neighbors, such as the moon and visiting meteorites, […]

Uranium dating is one of the ways of determining the age of ancient objects, even one million years old, by measuring how much of the following are present in them: the amount of radioactive isotopes of uranium, and the amount of other materials into which the radioactive isotopes would decompose Modern Uranium-series methods use decay chains and […]

How Does Carbon Dating Work Carbon-14 is a weakly radioactive isotope of Carbon; also known as radiocarbon, it is an isotopic chronometer. C-14 dating is only applicable to organic and some inorganic materials (not applicable to metals). Gas proportional counting, liquid scintillation counting and accelerator mass spectrometry are the three principal radiocarbon dating methods. What is […]

Along coastlines and kilometres inland, storm surge is one of the biggest threats to lives and property during hurricanes and storms. Hurricane evacuations are primarily due to storm surge, they have cost millions of lives and hundreds of billions of dollars in damages over the last century. Storm surge from Hurricane Haiyan in the Philippines left […]

Natural hazards WMO maintains rotating lists of names which are appropriate for each Tropical Cyclone basin. If a cyclone is particularly deadly or costly, then its name is retired and replaced by another one. Tropical cyclones can last for a week or more; therefore there can be more than one cyclone at a time. […]

Tropical cyclones are one of the biggest threats to life and property even in the formative stages of their development. They include a number of different hazards that can individually cause significant impacts on life and property, such as storm surge, flooding, extreme winds, tornadoes and lighting. Combined, these hazards interact with one another and […]
