It has been said before that the wars of the 21st century are hybrid wars, in the sense that, in addition to the environments in which the hostilities have taken place until now–land, water and air–a fourth environment has appeared: the virtual one.

Yelling at children—especially younger kids—appears to be effective. They stop whatever they’re doing (or not meant to be doing) and start obeying you.

We cannot sustain our motivation if we don't connect daily to its source and what generates it, or if we don't constantly strive to remind ourselves why we are moving in a certain direction and how to get there, willingly and unforced, exercising free will, despite the inevitable limitations.

In centuries long buried in the mists of time, the Bible was a book for which people were willing to die—whether burned at the stake or thrown into prison. There was a time when Bibles were chained to monastery walls. Today, they are printed and distributed by the millions. Yet it seems fewer people are actually reading them.

Attitudes toward food form a complex mosaic shaped by factors such as nutritional needs, hunger, taste preferences, socioeconomic status, demographic and emotional influences, as well as ethical, cultural, and religious values. Equally important is the level of education on nutrition (Gahagan, 2012). This plurality of factors helps explain the global diversity of dietary habits.

When a process is thought to be too slow or impractical to test experimentally, simulation science is a valuable tool for testing its validity.

Several simple experiments have shown that certain neural processes that are activated when performing an action increase in intensity with fractions of a second or even whole seconds before conscious thinking is informed about the performance of that action.

It happens to all of us. We misplace the keys, forget a phone number or where we put our reading glasses. With age, such things happen more often, whether we like it or not. The good news is, our brain continues to produce new cells regardless of our age. Therefore, it is possible to have a good memory despite the aging process.

The false dilemma fallacy presents an issue as if there are only two ways to solve it—often, two opposite ways—when, in fact, there are more ways than that. The conflict between the two ways presented is also false.

The obvious opposition to one of the most widespread Christian teachings is likely to provoke strong reactions, which is what happened with the book Immortality of the Soul or the Resurrection of the dead?,[1] by the renowned Lutheran theologian Oscar Cullmann (1902-1999).

The fact that we are able to anticipate most of the consequences of our actions is undoubtedly a blessing. However, we can also allow fear or over-cautiousness to make us anticipate events that are not likely to follow. This edges us toward a common error of judgement: the slippery slope.

Louis Braille said: "God was pleased to hold before my eyes the dazzling splendours of eternal hope. After that, doesn't it seem that nothing could keep me bound to the earth?"

Many will admit that they have never thought about this question because they live the status quo without critically evaluating it.

While few people can remember the details of their first hit, everyone can identify with the rush of satisfaction, the tingling delight that starts on the tip of your tongue and then courses through your entire body.

This is the part of the story most people know: Eric Liddell, a conscientious Christian athlete, refused to run in the heats for the 100-metre sprint at the 1924 Paris Olympics because they were held on a Sunday. Instead, he switched to the 400 metres, an event he had hardly trained for, and won the gold medal for Britain. The story of his...
