Time travel from ancient mythology to modern science

There’s no need to “like” every single status update your significant other posts, nor comment on it. Tell them in real life how you feel. If it’s not significant enough that you would call them and acknowledge it over the phone, it’s probably not necessary for you to bombard their wall. Image courtesy of Flickr, afagen 2. Timeline Contrary to what many movies made you think, your life is not a rom com — so don’t dramatize it. Beginning a relationship with someone is great, so simply enjoy it for what it is, and don’t worry about adding a lifetime event to your Timeline.

READ MORE Heritage of antiquity and the Middle Ages The physical sciences ultimately derive from the rationalistic materialism that emerged in classical Greece , itself an outgrowth of magical and mythical views of the world. The Greek philosophers of the 6th and 5th centuries bce abandoned the animism of the poets and explained the world in terms of ordinarily observable natural processes. These early philosophers posed the broad questions that still underlie science: How did the world order emerge from chaos?

His theory generally fitted the data available to him with a good degree of accuracy, and his book, the Almagest , became the vehicle by which Greek astronomy was transmitted to astronomers of the Middle Ages and Renaissance.

But our ideas about attraction and love are actually being shaped there. Not too long ago, relationships and dates would largely be limited to the people you encountered in real-life, but with the advent of online dating, all of that has changed. With an elegant experimental setup that was configured in iMotions, Tom and colleagues were able to present 27 participants with a Tinder replica, asking them to accept or reject swiping right or left, respectively the photos of 30 potential matches.

As the stimuli are essentially so simple, it is relatively straightforward to manipulate each image, to see how the changing of each parameter affects the outcome — if the participant desires the person in the image, or not. EEG an ABM B-Alert X10 Eye tracking with a Tobii X Behavioral measures accepting or rejecting the photos With this approach they were able to extract information about brain activity while the participants looked, and reacted to the images.

One of the crucial pieces of information that they used was a measure of prefrontal asymmetry — a recording of brain activity that relates to the difference in activity between the two frontal lobes. By combining these measures, the researchers were able to determine the brain activity of participants in a moment-to-moment basis, and thus tie this to the images that the participants saw. The researchers used eye tracking, EEG, and behavioral measures to gather data about online dating experiences.

This showed that increased brain engagement is linked to the attractiveness of the image.

How to convince someone to change their mind, according to science

Asa Gilbert Eddy m. Her father, Mark Baker, was a deeply religious man, although, according to one account, “Christianity to him was warfare against sin, not a religion of human brotherhood. Eddy or “our beloved Leader”—was still included in all articles published in the Christian Science journals. She stood before us, seemingly slight, graceful of carriage, and exquisitely beautiful even to critical eyes. Then, still standing, she faced her class as one who knew herself to be a teacher by divine right.

She turned to the student at the end of the first row of seats and took direct mental cognizance of this one, plainly knocked at the door of this individual consciousness.

The Mesopotamians discovered glass, probably from glass beads in the slag resulting from experiments with refining metallic ores.

In fact, it appears that the possibility to travel in time, either into the future or into the past, has appealed to the imagination of mankind for centuries. Albert Einstein for example, concluded in his later years that the past, present, and future all exist simultaneously, and most are familiar with his well-known concept of relativity. That is, that time is relative and not absolute as Newton claimed. With the proper technology, such as a very fast spaceship, one person is able to experience several days while another person simultaneously experiences only a few hours or minutes.

Yet the wisdom of Einstein’s convictions had very little impact on cosmology or science in general. The majority of physicists have been slow to give up the ordinary assumptions we make about time. However, if time travel really was possible, one can hardly contemplate what this may mean for humanity for whoever has the power to move through time, has the power to modify history. While this may sound attractive, it would be impossible to know the consequences of any alteration of past events, and how this would affect the future.

Time travel in ancient mythology If we look into ancient texts we can find a number of references to time travelling. In Hindu mythology, there is the story of King Raivata Kakudmi who travels to meet the creator Brahma. The explanation Brahma gave to Kakudmi is that time runs differently in different planes of existence.

Similarly, we have references in the Quran about the cave of Al-Kahf. They woke up years later. This story coincides with the Christian story of the seven sleepers , with a few differences.

History of Technology Heroes and Villains – A little light reading Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved.

You may find the Search Engine , the Technology Timeline or the Hall of Fame quicker if you are looking for something or somebody in particular. Scroll down and see what treasures you can discover. Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind.

Henry VIII in , aware of the power of the press, became the first monarch to publish a list of banned books though he did not go so far as banning printing.

Nature philosophy Maize , known in some English-speaking countries as corn, is a large grain plant domesticated by indigenous peoples in Mesoamerica in prehistoric times Before the invention or discovery of the concept of ” nature ” ancient Greek phusis by the Pre-Socratic philosophers , the same words tend to be used to describe the natural “way” in which a plant grows, [12] and the “way” in which, for example, one tribe worships a particular god.

For this reason, it is claimed these men were the first philosophers in the strict sense, and also the first people to clearly distinguish “nature” and “convention. They were mainly speculators or theorists , particularly interested in astronomy. The Socratic method as documented by Plato ‘s dialogues is a dialectic method of hypothesis elimination: This was a reaction to the Sophist emphasis on rhetoric.

The Socratic method searches for general, commonly held truths that shape beliefs and scrutinizes them to determine their consistency with other beliefs. Socrates was later, in the words of his Apology, accused “because he corrupts the youth and does not believe in the gods the state believes in, but in other new spiritual beings”. Socrates refuted these claims, [24] but was sentenced to death.

Motion and change is described as the actualization of potentials already in things, according to what types of things they are. In his physics, the sun goes around the earth, and many things have it as part of their nature that they are for humans. Each thing has a formal cause , a final cause , and a role in a cosmic order with an unmoved mover. While the Socratics insisted that philosophy should be used to consider the practical question of the best way to live for a human being a study Aristotle divided into ethics and political philosophy , they did not argue for any other types of applied science.

Aristotle maintained that man knows a thing scientifically “when he possesses a conviction arrived at in a certain way, and when the first principles on which that conviction rests are known to him with certainty”.

Why does a bee only visit one type of flower at a time? It seems such a waste of energy. I read that a supermarket won an award for its two-year-matured puddings. So, what happens over two years to bring out the flavour? Where I live, I use five different bins and the collections are fortnightly. Unlike many people I observe, I squash things like aluminium cans and plastic milk bottles.

But even without the wars, the delicate papyrus scrolls were apt to disintegrate with age and what was left of the library eventually succumbed to the ravages of major earthquakes in Crete in A.

Science How to convince someone to change their mind, according to science Whether in the form of Twitter feuds or political debates, the universe is constantly clamouring to change your mind Thursday 11 February But how many of these appeals to alter our views really succeed? A new paper from researchers at Cornell University sheds some light on how and why people are convinced to change their minds.

The researchers analyzed nearly two years of postings on ChangeMyView, a forum on the internet community reddit where posters present an argument and invite people to reason against them. These arguments on ChangeMyView range widely in terms of topic. The image’s colours have been enhanced after it was sent back to Earth. The tallest of the skeletons uncovered measured at 1.

Impress your friends with these incredible facts about the world around us. This extra flexibility helps them pass through the birth canal and also allows for rapid growth. The Eiffel Tower can be 15 cm taller during the summer Large structures are built with expansion joints which allow them some leeway to expand and contract without causing any damage. When a substance is heated up, its particles move more and it takes up a larger volume — this is known as thermal expansion.

The vast majority of living organisms on Earth need oxygen to survive, converting it into carbon dioxide as they breathe.

At the same time, neuroscientists have discovered that the brain is much more plastic — more influenced by experience — than we used to think.

And, as I already mentioned, alpha is often associated with what is known as superlearning—the ability to learn, process, store and… …recall large amounts of information quickly and efficiently. Slower still are theta waves. Theta is best known as the brain wave state of dreaming sleep, but it is also associated with a number of other beneficial states, including increased creativity, some kinds of superlearning, increased memory abilities, visionary experiences, and what are called integrative experiences where we make broadly-based positive changes in the way we see ourselves, others, or certain life situations.

You can probably see why gaining the ability and flexibility to access this state might increase your effectiveness! And best of all, theta is also a state of tremendous stress relief. In the slower theta brain wave pattern, the brain makes lots of relaxing endorphins that really do—as you will see or rather, feel when you try it for yourself… …melt your stress away!

The slowest brain wave pattern is delta, the brain wave pattern of dreamless sleep. In certain delta frequencies the brain releases many highly beneficial substances, including human growth hormone, which we ordinarily make in decreasing quantities as we get older—resulting in many aging symptoms including loss of muscle tone, increased weight gain, loss of stamina, and many diseases associated with aging.

The positive evidence is overwhelming.

This has changed over the past few decades because of the dramatic advances in digital imaging technologies and computer power. One of the best examples of this was the computer artistry of Ray Downing, whose digital re-creation of Jesus based on the Shroud was documented in “The Real Face of Jesus” program that appeared on the History Channel. In the past few years, digital artists around the world have been able to render their own interpretations of how Jesus may have appeared based on the Shroud and these show up from time to time on the internet.

However, throughout all those years, not one artist has attempted to create an interpretation of what Mary, Mother of Jesus looked like based on the Shroud image. Until now, that is.

Archimedes also founded the studies of statics and hydrostatics and was the first to elucidate the principle of buoyancy and to use it in practical applications.

Continue reading the main story But there are two very different kinds of innateness. Chomsky proposed that we are born with specific, genetically determined neural and cognitive structures, structures that go far beyond a few general learning mechanisms. This kind of innateness has become the established wisdom in cognitive science.

The brain is not a blank slate. However, the other, more significant, kind of innateness concerns not the history of the mind but its future. Chomsky also argued that innate structure places very strong constraints on the human mind. Evolutionary psychologists who echo Chomsky say we are stuck with the same brains as our hunter-gatherer ancestors, with just a little tinkering around the edges.

Many social scientists reject this second claim. A new generation of cognitive scientists and neuroscientists are starting to reject it, too. At the same time, neuroscientists have discovered that the brain is much more plastic — more influenced by experience — than we used to think. The brain is highly structured, but it is also extremely flexible.
