What happens when we unexpectedly see an attractive potential partner? Previous studies in laboratorial settings suggest that the visualization of attractive and unattractive photographs influences time. The major aim of this research is to study time perception and attraction in a realistic social scenario, by investigating if changes in subjective time measured during a speed dating are associated with attraction. […]

When there is a perception of the partner as being physically more attractive, women tend to overestimate the duration of that meeting, whereas men tend to underestimate its duration.

Let’s begin with a simple fact: time passes faster in the mountains than it does at sea level. The difference is small but can be measured with precision timepieces that can be bought today for a few thousand pounds. This slowing down can be detected between levels just a few centimetres apart: a clock placed on the floor runs a little more slowly than one on a table.

It is not just the clocks that slow down: lower down, all processes are slower. Two friends separate, with one of them living in the plains and the other going to live in the mountains. They meet up again years later: the one who has stayed down has lived less, aged less, the mechanism of his cuckoo clock has oscillated fewer times. He has had less time to do things, his plants have grown less, his thoughts have had less time to unfold … Lower down, there is simply less time than at altitude. […]

Times are legion: a different one for every point in space. The single quantity “time” melts into a spiderweb of times.

‘Once you are born in this world you’re old enough to die.’ ―Kierkegaard

Several temporal paradoxes exist in physics. These include General Relativity’s grandfather and ontological paradoxes and Special Relativity’s Langevin-Einstein twin-paradox. General relativity paradoxes can exist due to a Gödel universe that follows Gödel’s closed timelike curves solution to Einstein’s field equations.

A novel biological temporal paradox of General Relativity is proposed based on reproductive biology’s phenomenon of heteropaternal fecundation. Herein, dizygotic twins from two different fathers are the result of concomitant fertilization during one menstrual cycle. In this case an Oedipus-like individual exposed to a Gödel closed timelike curve would sire a child during his maternal fertilization cycle.

As a consequence of heteropaternal superfecundation, he would father his own dizygotic twin and would therefore generate a new class of autofraternal superfecundation, and by doing so creating a ‘twin-father’ temporal paradox.

Whereas women of all ages prefer slightly older sexual partners, men—regardless of their age—have a preference for women in their 20s. Earlier research has suggested that this difference between the sexes’ age preferences is resolved according to women’s preferences. This research has not, however, sufficiently considered that the age range of considered partners might change over the life span.

Here we investigated the age limits (youngest and oldest) of considered and actual sex partners in a population-based sample of 2,655 adults (aged 18-50 years). Over the investigated age span, women reported a narrower age range than men and women tended to prefer slightly older men. We also show that men’s age range widens as they get older: While they continue to consider sex with young women, men also consider sex with women of their own age or older.

Contrary to earlier suggestions, men’s sexual activity thus reflects also their own age range, although their potential interest in younger women is not likely converted into sexual activity. Homosexual men are more likely than heterosexual men to convert a preference for young individuals into actual sexual behavior, supporting female-choice theory.

For hundreds of years, Koreans have used a different method to count age than most of the world. […] A person’s Korean age goes up a year on new year’s day, not on his or her birthday. So when a baby is born on Dec. 31, he or she actually turns two the very next day.

Einstein wondered what would happen if the Sun were to suddenly explode. Since the Sun is so far away that it takes light eight minutes to travel to Earth, we wouldn’t know about the explosion straight away. For eight glorious minutes we’d be completely oblivious to the terrible thing that was about to happen.

But what about gravity? The Earth moves in an ellipse around the Sun, due to the Sun’s gravity. If the Sun wasn’t there, it would move off in a straight line. Einstein’s puzzle was when that would happen: straight away, or after eight minutes? According to Newton’s theory, the Earth should know immediately that the Sun had disappeared. But Einstein said that couldn’t be right. Because, according to him, nothing can travel faster than the speed of light — not even the effects of gravity. […]

Before Einstein people thought of space as stage on which the laws of physics play out. We could throw in some stars or some planets and they would move around on this stage.

Einstein realised that space isn’t as passive as that. It is dynamic and it responds to what’s happening within it. If you put something heavy in space — let’s say a planet like Earth — then space around it gives a little. The presence of the planet causes a small dent in space (and in fact, in time as well). When something else moves close to the planet — say the Moon — it feels this dent in space and rolls around the planet like a marble rolling in a bowl. This is what we call gravity. […] Stars and planets move, causing space to bend in their wake, causing other stars and planets to move, causing space to bend in their wake. And so on. This is Einstein’s great insight. Gravity is the manifestation of the curvature of space and time.

49 days, surely I should be feeling a whole lot better

Does morality depend on the time of the day? The study “The Morning Morality Effect: The Influence of Time of Day on Unethical Behavior” published in October of 2013 by Maryam Kouchaki and Isaac Smith suggested that people are more honest in the mornings, and that their ability to resist the temptation of lying and cheating wears off as the day progresses. […]

One question not addressed by Kouchaki and Smith was whether the propensity to become dishonest in the afternoons or evenings could be generalized to all subjects or whether the internal time in the subjects was also a factor.

All humans have an internal body clock — the circadian clock — which runs with a period of approximately 24 hours. The circadian clock controls a wide variety of physical and mental functions such as our body temperature, the release of hormones or our levels of alertness. The internal clock can vary between individuals, but external cues such as sunlight or the social constraints of our society force our internal clocks to be synchronized to a pre-defined external time which may be quite distinct from what our internal clock would choose if it were to “run free”. Free-running internal clocks of individuals can differ in terms of their period (for example 23.5 hours versus 24.4 hours) as well as the phases of when individuals would preferably engage in certain behaviors. […]

Some people like to go to bed early, wake up at 5 am or 6 am on their own even without an alarm clock and they experience peak levels of alertness and energy before noon. In contrast to such “larks”, there are “owls” among us who prefer to go to bed late at night, wake up at 11 am, experience their peak energy levels and alertness in the evening hours and like to stay up way past midnight. […]

The researchers Brian Gunia, Christopher Barnes and Sunita Sah therefore decided to replicate the Kouchaki and Smith study with one major modification: They not only assessed the propensity to cheat at different times of the day, they also measured the chronotypes of the study participants. Their recent paper “”The Morality of Larks and Owls: Unethical Behavior Depends on Chronotype as Well as Time of Day” confirms that Kouchaki and Smith findings that the time of the day influences honesty, but the observed effects differ among chronotypes. […]

[M]orning morality effect and the idea of “moral exhaustion” towards the end of the day cannot be generalized to all. In fact, evening people (”owls”) are more honest in the evenings. […]

Gunia and colleagues only included morning and evening people in their analysis and excluded the participants who reported an intermediate chronotype, i.e. not quite early morning “larks” and not true “owls”. This is a valid criticism because newer research on chronotypes has shown that there is a Gaussian distribution of chronotypes. Few of us are extreme larks or extreme owls, most of us lie on a continuum.

If I go every other day I will be at the gym 4-5 times a week, is that over training?
I typically work out for 60-90 minutes, I push my self and raise the weight each week.

[…]

steviekm3
That makes no sense. There are only 7 days in a week. If you go every other day that is 3.5 times a week.

TheJosh
Monday, Wednesday, Friday, Sunday. That is 4 days.
How do you go 3.5 times? Do a half workout or something? lol

Justin-27
7x in 2 weeks = 3.5 times a week, genius.
And yeah, 3x a week, full body workouts are good.

TheJosh
I never said anything about going exactly 7 times, like I said, if I go every other day, that is 4 DAYS A WEEK. How hard is that to comprehend?
Week 1 - Sunday, Tuesday, Thursday, Saturday
Week 2 - Monday, Wednesday, Friday, Sunday.
8 DAYS IN 2 WEEKS
In your terms,
8x in 2 weeks = 4 times a week, genius.
All Muscle and No Brains? lol

steviekm3
You double counted Sunday - that is 2 weeks plus 1 day.
Did you fail grade 2 math ?
PLUS your old post said 4 or 5 times a week. Now you just neglect to mention the 5.
Grow up and admit when you are wrong. Believe me you will get a a lot further in life this way.

TheJosh
Are you retarded?
Maybe you should look at a calander, I didn’t double count sunday, my two weeks started and ended on sunday, exactly 14 days.
What don’t you understand?
EDIT - Here is a Calender, I made little dots for each day so you could comprehend.

Justin-27
Dude THAT IS 15 DAYS!!!!!! You can’t have a week go Sun-Sat, then Sun-Sun. Look at the damn pic you posted, count the days what do they equal?!?!?! FIFTEEN!
I was right, 3.5 x a week, and so was the first guy to post it, and you my bright friend are el wrongo.

[…]

TheJosh
There is 7 days in a week, if you workout every other day, you work out 4 days a week, how hard is that to ****ing comprehend?!
Ill do it out in 4 weeks for you, maybe it will make more sense?
Week 1 - Sunday, Tuesday, Thursday, Saturday
Week 2 - Monday, Wednesday, Friday, Sunday
Week 3 - Tuesday, Thursday, Saturday, Monday
Week 4 - Wednesday, Friday, Sunday, Tuesday
Week 5 - Thursday, Saturday, Monday, Wednesday
Week 6 - Friday, Sunday, Tuesday, Thursday
No matter how you look at it, if you workout every other day, you work out 4 times a week.
[…]
A week is sunday-sunday.
I think you just don’t know how to count, it’s alright, I won’t tell anyone. lol
Sunday-Saturday is only 6 days, do you have 6 days weeks where you live?

Justin-27
Yes, you workout 4x the first week, then 3 the next.
I’m right, you’re a effing moron.

Sun-Sat is only 6 days?!
Sunday ONE
Monday TWO
Tuesday THREE
Wednesday FOUR
Thursday FIVE

The time is out of joint

354.jpg

O’Brian oversees America’s master clock. It’s one of the most accurate clocks on the planet: an atomic clock that uses oscillations in the element cesium to count out 0.0000000000000001 second at a time. If the clock had been started 300 million years ago, before the age of dinosaurs began, it would still be keeping time — down to the second. […]

At the nearby University of Colorado Boulder is a clock even more precise than the one O’Brian watches over. […] This new clock can keep perfect time for 5 billion years.”It’s about the whole, entire age of the earth,” says Jun Ye, the scientist here at JILA who built this clock. […]

But this new clock has run into a big problem: This thing we call time doesn’t tick at the same rate everywhere in the universe. Or even on our planet.

Right now, on the top of Mount Everest, time is passing just a little bit faster than it is in Death Valley. That’s because speed at which time passes depends on the strength of gravity. Einstein himself discovered this dependence as part of his theory of relativity, and it is a very real effect.

The relative nature of time isn’t just something seen in the extreme. If you take a clock off the floor, and hang it on the wall, Ye says, “the time will speed up by about one part in 1016.” […] Time itself is flowing more quickly on the wall than on the floor. These differences didn’t really matter until now. But this new clock is so sensitive, little changes in height throw it way off. Lift it just a couple of centimeters, Ye says, “and you will start to see that difference.” […]

The world’s current time is coordinated between atomic clocks all over the planet. But that can’t happen with the new one.

Creeps in this petty pace from day to day

Findings from two experiments suggest that priming the passage of time through the sound of a ticking clock influenced various aspects of women’s (but not men’s) reproductive timing. Moreover, consistent with recent research from the domain of life history theory, those effects depended on women’s childhood socioeconomic status (SES). The subtle sound of a ticking clock led low (but not high) SES women to reduce the age at which they sought to get married and have their first child (Study 1), as well as the priority they placed on the social status and long-term earning potential of potential romantic partners (Study 2).

‘I’d hate to die twice.’ —Richard Feynman

Since 1990, the Gerontology Research Group has assumed the role of record keepers for the world’s supercentenarians, or persons older than 110. […]

When it comes to age forgery, Coles has seen it all. He recently received a claim from India of an individual who is supposedly 179—a feat that is almost certainly physically impossible. The deceit can be harder to spot, such as the time a man in Turkey tried to pass himself off as his deceased brother, who was ten years older. And in one particularly challenging case, the government of Bolivia issued false documents to a man who was 106, stating that he was 112.

These problems are well known among those who study the very old. “Ninety-eight percent of ages claimed over 115 are false,” says Thomas Perls, a professor of medicine and geriatrics at Boston Medical Center, and director of the New England Centenarian Study. Based on a research paper he published on the topic, Perls says that “There’s a total of ten different major reasons why people do this.”

Sometimes, the motivation for lying is monetary. In the U.S., for example, a handful of people inflated their ages in order to claim to be Civil War veterans, giving them access to pensions. […] In other cases, a government or group might want to demonstrate that theirs is a “superior race.”
