Vanishing white matter (VWM) is a genetic disease of the central nervous system that can be hereditary or caused by specific events such as high fever or head injury. The disease causes the white matter of the brain to disintegrate, leading to loss of motor and neurological function, seizures, and eventually coma and death. There […]
When hiring a subject matter expert, evaluate their credentials, experience, and ability to meet deadlines. Subject matter experts are often relied upon by companies for educational courses and training materials, and their qualifications should be consistent with recognized authorities in their field. Other considerations include industry recognition, teaching experience, and publication history. When choosing a […]
Volatile matter is a substance that vaporizes easily, measured by its vapor pressure. It determines flammability and is used to test coal properties for industrial use. VOCs are organic compounds with high volatility, causing respiratory health risks. Volatile matter is any substance that has a tendency to vaporize under the right conditions. The volatility of […]
In the remote Indian village of Banej, the only human resident, Guru Baharatdas Darshandas, consistently votes in every election. Workers set up a voting booth for him at the local temple, where he is the keeper. Despite not knowing the candidates, Darshandas believes his vote makes a difference. Compulsory voting is practiced in Australia, while […]
Google’s Gmail service ignores periods and is not case sensitive in email addresses. Microsoft Outlook, Yahoo Mail, and Apple iCloud recognize periods. Gmail has over 1 billion users worldwide. When Google began offering its free email service in 2004, the tech company did a few things differently, like ignoring periods in users’ email addresses. So […]
Matter waves, discovered by de Broglie, are the wave-particle nature of all matter. The wavelength of matter is very small and barely perceptible. De Broglie’s theory was confirmed in 1927 when scientists fired slow electrons at a crystalline nickel target, demonstrating wave-like characteristics. Matter waves, also called de Broglie waves, are the wave nature of […]
The law of conservation of matter states that matter in a closed system cannot be created or destroyed. Antoine-Laurent Lavoisier discovered this principle through experiments in sealed chambers and is considered the father of modern chemistry. Albert Einstein later showed that matter and energy are interchangeable. Lavoisier was unable to complete his experiments due to […]
Degenerate matter is an exotic form of matter found in the cores of massive stars, where particles are packed so tightly that the primary source of pressure is quantum. It includes metallic hydrogen, white dwarf matter, neutronium, strange matter, and quark matter. Its pressure is only partially dictated by temperature and is stable even at […]
Zero gravity, or weightlessness, occurs in orbit or in space away from celestial bodies. Objects float and flames become spherical, but dust and clutter can create a messy environment. Zero gravity can also have negative effects on the human body, including weakened bones and muscles, slowed blood circulation, and excess flatulence. To counteract these effects, […]
Questions of law involve the interpretation of the law and are decided by a judge, while matters of fact concern concrete facts and are decided by a jury. Appeals usually focus on questions of law, and judges may issue written opinions that become part of the jurisprudence. A question of law is a question that […]
Recurring dreams can reveal unsolved problems, constant fears, or excitement about future events. Keeping a dream journal can help identify emotions and provide insight into oneself. You may have had the experience of waking up to realize you had a familiar dream. Recurring dreams are a common phenomenon, with several explanations. Some experts consider them […]
In a 2009 British court case, judges had to decide whether Pringles were crisps or something else, as this determined whether they were subject to VAT. The company argued they were not potato chips due to their many ingredients, but the Court of Appeal ruled that a hypothetical 8-year-old boy would call them potato chips. […]
A British court case in 2009 asked whether Pringles were crisps or something else, as this determined whether they were subject to VAT. Procter & Gamble argued they were not potato chips, but the Court of Appeal asked a hypothetical 8-year-old boy who decided they were. Procter & Gamble had to continue paying the tax. […]
Parkinson’s disease prognosis can be improved with early diagnosis, quality medical care, medication, physical therapy, and emotional support. Age, severity of symptoms, and family history also play a role. Parkinson’s disease is a lifelong, incurable neurological disorder that gets progressively worse over time. The prognosis may seem dismal, but modern advances in diagnostic tools, drugs, […]
Dark matter is a mysterious substance that makes up 90% – 99% of the universe’s matter. Its existence was first suggested in the 1930s by astronomers Fritz Zwicky and Sinclair Smith, who observed that galaxies were moving faster than they should be. Further evidence came in the 1970s when scientists analyzed the rotation curves of […]
Heat energy can be transferred through conduction, convection, and radiation. Objects of different temperatures will try to reach thermal equilibrium, transferring heat from hot to cold. Conduction occurs when molecules transfer heat by bumping into each other, while convection involves the transfer of heat through the movement of fluids. Radiation is the transfer of heat […]
Particulate matter is small solids or liquids in the air, with primary particles directly from a source and secondary particles forming in the air. They range in size from 2-3 molecules to visible chunks and can cause breathing problems and changes in solar radiation. Sources include roads, fossil fuels, and natural events. Particulate matter describes […]
Federal matters jurisdiction is the power granted to US federal courts to hear cases relating to the Constitution or federal laws. It overrides state court jurisdiction and requires a relevant claim in the complaint. The US Supreme Court determines which cases fall under federal jurisdiction. Federal matters jurisdiction refers to the power granted to the […]
A subject matter expert (SME) is an individual with specialized skills and experience in a specific field, often working in education, software development, or customer service. SMEs are employed to provide area-specific knowledge to teams with broad technical skills, and effective collaboration is crucial. Technical training and hands-on experience are typically required to become a […]
