Astrology and astronomy

01-03-2022 Grenius.org Astrology and astronomy
Astrology and astronomy were archaically treated together (Latin: astrologia), and were only gradually separated in Western 17th century philosophy (the 'Age of Reason') with the rejection of astrology. During the later part of the medieval period, astronomy was treated as the foundation upon which astrology could operate. Since the 18th century they have come to be regarded as completely separate disciplines. Astronomy, the study of objects and phenomena originating beyond the Earth's atmosphere, is a science and is a widely studied academic discipline. ...

Astronomy

01-02-2022 Grenius.org Astronomy
Astronomy (from Greek, literally meaning the science that studies the laws of the stars) is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded...

Astrology

01-01-2022 Grenius.org Astrology
Astrology is a pseudoscience that claims to discern information about human affairs and terrestrial events by studying the movements and relative positions of celestial objects. Astrology has been dated to at least the 2nd millennium BCE, and has its roots in calendrical systems used to predict seasonal shifts and to interpret celestial cycles as signs of divine communications. Many cultures have attached importance to astronomical events, and some-such as the Hindus, Chinese, and the Maya-developed elaborate systems for predicting terrestrial events from celestial observations. Western astrology, one of the oldest astrological systems still in use, can trace its roots to 19th-17th century BCE Mesopotamia, from where it...

Hydrogen

01-12-2021 Grenius.org Hydrogen
Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula H2. It is colorless, odorless, non-toxic, and highly combustible. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all normal matter. Stars such as the Sun are mainly composed of hydrogen in the plasma state. Most of the hydrogen on Earth exists in molecular forms such as water and organic compounds. For the most common isotope of hydrogen (symbol 1H) each atom has one proton, one electron, and no neutrons. In the early universe, the formation of protons, the nuclei of...

LGBTQIAP+

01-11-2021 Grenius.org LGBTQIAP+
LGBTQIAP+ is an initialism that stands for lesbian, gay, bisexual, and transgender. In use since the 1990s, the initialism, as well as some of its common variants, functions as an umbrella term for sexuality and gender identity. It may refer to anyone who is non-heterosexual or non-cisgender, instead of exclusively to people who are lesbian, gay, bisexual, or transgender. To recognize this inclusion, a popular variant, LGBTQ, adds the letter Q for those who identify as queer or are questioning their sexual or gender identity. History of the term The Stonewall Inn in the gay village of Greenwich Village, Manhattan, site of the June 1969 Stonewall riots, the cradle of the modern LGBT rights movement and an icon...

Energy label

01-10-2021 Grenius.org Energy label
EU Directive 92/75/EC established an energy consumption labelling scheme. The directive was implemented by several other directives thus most white goods, light bulb packaging and cars must have an EU Energy Label clearly displayed when offered for sale or rent. The energy efficiency of the appliance is rated in terms of a set of energy efficiency classes from A to G on the label, A being the most energy efficient, G the least efficient. The labels also give other useful information to the customer as they choose between various models. The information should also be given in catalogues and included by internet retailers on their websites. In an attempt to keep up with advances in energy efficiency, A+, A++ and A+++ grades were...

Co2/Carbon neutral

01-08-2021 Grenius.org Co2/Carbon neutral
Carbon neutrality is a state of net-zero carbon dioxide emissions. This can be achieved by balancing emissions of carbon dioxide with its removal (often through carbon offsetting) or by eliminating emissions from society (the transition to the 'post-carbon economy'). The term is used in the context of carbon dioxide-releasing processes associated with transportation, energy production, agriculture, and industry. Although the term 'carbon neutral' is used, a carbon footprint also includes other greenhouse gases, measured in terms of their carbon dioxide equivalence. The term climate-neutral reflects the broader inclusiveness of other greenhouse gases in climate change, even if CO2 is the most abundant. The term 'net...

Climate change Explaining climate change and global warming The global climate has been changing since time began and will continue to change into the future. The Earth's temperature has fluctuated in the last few hundred years. Examining the causes of climate change and the greenhouse effect Past climate change The Earth's average temperature has changed over the last 500,000 years. There are times when the global climate is warmer (interglacial phases) and times when it has been cooler (glacial phases), when there have been ice ages. The last major cold period was known as the Pleistocene, started 2.6 million years ago and ended just 10,000 years ago. Since then, conditions have...

How Dams Are Reshaping the World for the Better and Worse You have likely seen a dam before and may even benefit from its energy-producing capacity. But do you really know what a dam is and how it works? Do you also know that dams reshape the world around us in incredible ways? Dams cause earthquakes but they also produce much-needed energy. Want to hear more about the many current and future dams around the world and their stories both good and bad? Did you know that China's Three Gorges Dam, for instance, is so massive that it slows the Earth's rotation? When the dam is at capacity, its reservoir holds 42 billion tons of water which is actually enough to create a shift in mass powerful enough...

The Engineering Behind Cloud Seeding: The Art of Creating Rain

01-05-2021 Grenius.org The Engineering Behind Cloud Seeding: The Art of Creating Rain
The Engineering Behind Cloud Seeding: The Art of Creating Rain Cloud seeding produces rain by manipulating clouds. Did you know that countries across the globe are using some sort of weather modification program? In fact, the technology, although very cutting-edge, has been around for more than 75 years and is only set to grow in popularity as climate change takes its toll on the planet. One form of weather modification is cloud seeding. This is a technology that produces rain by manipulating clouds. The technology can even be used to engineer snow or smaller hail pellets. How does it work? Chemicals such as silver iodide, potassium iodide, or solid carbon dioxide (dry ice) are shot into...

Earth's Magnetic North Pole Continues Drifting

01-03-2021 Grenius.org Earth's Magnetic North Pole Continues Drifting
Earth's magnetic north pole Earth's magnetic north pole, which has been wandering faster than expected in recent years, has now crossed the prime meridian. The team of researchers that maintain the World Magnetic Model (WMM) has updated it and released it a year ahead of schedule due to the speed with which the pole is moving. The newly updated model shows the magnetic north pole moving away from Canada and toward Siberia. True north The magnetic north pole is the point on the Earth that compasses designate as true north. It is the result of geological processes deep within the planet-molten iron flow creates a magnetic field with poles near the geographic North and South Poles. But unlike the...

Aluminum in cosmetics / deodorants / dermal products dangerous to health

01-11-2020 Grenius.org Aluminum in cosmetics / deodorants / dermal products dangerous to health
The potential toxicity of aluminum in cosmetics has been a concern for several years. Often accused of promoting breast cancer or Alzheimer's disease, he was the subject of an assessment by the National Agency for the Safety of Medicines and Health Products regarding his job security. The Agency has just published its conclusions in an expert report published on 17 November 2011. Conclusion: the risk exists and consumer health safety is not ensured. The issue has been studied by French health authorities since 2000. In 2003, a first report was published highlighting the lack of relevant data on dermal absorption of aluminum from cosmetic products. It was then impossible to conclude on the risks associated...

Waste sorting

01-10-2020 Grenius.org Waste sorting
Waste sorting is the process by which waste is separated into different elements. Waste sorting can occur manually at the household and collected through curbside collection schemes, or automatically separated in materials recovery facilities or mechanical biological treatment systems. Hand sorting was the first method used in the history of waste sorting. Waste can also be sorted in a civic amenity site. "Waste segregation" means dividing waste into dry and wet. Dry waste includes wood and related products, metals and glass. Wet waste typically refers to organic waste usually generated by eating establishments and are heavy in weight due to dampness.
