Historical thinking

Historical thinking is defined by many education resources as a set of reasoning skills that students of history should learn as a result of studying history. Sometimes called historical reasoning skills, historical thinking skills are frequently described in contrast to history content such as names, dates, and places. This dichotomous presentation is often misinterpreted as …

Bread and circuses

“Bread and circuses” (or bread and games; from Latin: panem et circenses) is metonymic for a superficial means of appeasement. In the case of politics, the phrase is used to describe the generation of public approval, not through exemplary or excellent public service or public policy, but through diversion; distraction; or the mere satisfaction of …

Global Warming in a Climate of Ignorance

It’s one of the greatest controversies in modern times: the question of whether human activity is the cause of changes in Earth’s climate. Today, we are told that institutional science and academia unite in consensus that the hypothesis of manmade global warming is no longer a hypothesis, but a science fact. Ironically, coincident with this …

A new form of matter – time crystals

If crystals have an atomic structure that repeats in space, like the carbon lattice of a diamond, why can’t crystals also have a structure that repeats in time? That is, a time crystal? … Two groups followed Yao’s blueprint and have already created the first-ever time crystals. The groups at the University of Maryland and …

Information warfare

Information warfare (IW) is a concept involving the use and management of information and communication technology in pursuit of a competitive advantage over an opponent. Information warfare may involve collection of tactical information, assurance(s) that one’s own information is valid, spreading of propaganda or disinformation to demoralize or manipulate[citation needed] the enemy and the public, …

Probability theory

Probability Probability is the measure of the likelihood that an event will occur. Probability is quantified as a number between 0 and 1 (where 0 indicates impossibility and 1 indicates certainty). The higher the probability of an event, the more certain that the event will occur. A simple example is the tossing of a fair …

The field is the more fundamental entity

I will quote Barak Shoshany answer to the question “What is the relationship between a particle and a field?” on Quora: A field is a mathematical entity that exists throughout space and time. A classical field is simply a function that has a numerical value at each point in spacetime. Think, for example, of the …

Anti-Zeno Effect

Unstable quantum systems are predicted to exhibit a short time deviation from the exponential decay law. This universal phenomenon has led to the prediction that frequent measurements during this nonexponential period could inhibit decay of the system, one form of the quantum Zeno effect. Subsequently, it was predicted that an enhancement of decay due to …

Cancer drugs do not even extend life for 10 weeks

Patients, advocates, and care providers are growing increasingly frustrated that new and often very pricey cancer drugs do little to improve patients’ survival, Kaiser Health News reports. For instance, the 72 cancer therapies approved between 2002 and 2014 only bought patients an extra 2.1 months of life compared with older drugs, researchers have found. And …
