For this Wednesday’s Wonderful World of Wikipedia we try to figure out if there is there a year 0, a year between 1 B.C. and 1 A.D.?
A gravity hill, also known as a magnetic hill (and sometimes a mystery hill or a gravity road), is a place where the layout of the surrounding land produces the optical illusion that a very slight downhill slope appears to be an uphill slope. Thus, a car left out of gear will appear to be rolling uphill. There are hundreds of known gravity hill locations around the world. These “paranormal” sites also tend to have names like “Haunted Hill”, “Magnetic Hill”, or “Anti-gravity Hill”, reflecting attribution by local folklore of the unusual properties of the area to such “mysteries” as the supernatural or magnetism. While humans also have a sense of balance to determine the inclination of the ground, visual cues can override this sense, especially if the inclination is shallow. This wikipedia link also lists all known gravity hill locations.
Technically you only need one reason, actually, any reason. But you are so much more complicated than that, aren’t you?
Well that is what psychologists Cindy Meston and Dr. Dave Buss, professors of psychology at the University of Texas at Austin, think. In fact, they have put out a report (pdf) analyzing 327 reasons people have sex. That’s pretty complicated in my book. The reasons breakdown into four major groups, each of the breakdown into 13 subgroups as follows:
- Stress reduction
- Social Status
- Love and commitment
- Self-esteem boost
- Mate guarding
According to the study, the most and least frequently endorsed reasons for having sex were common among the great majority who were surveyed. There were nine themes that appeared to characterize the most frequently endorsed reasons for having intercourse:
- pure attraction to the other person in general
- experiencing physical pleasure
- expression of love
- having sex because of feeling desired by the other
- having sex to escalate the depth of the relationship
- curiosity or seeking new experiences
- marking a special occasion for celebration
- mere opportunity
- sex just happening due to seemingly uncontrollable circumstances
Their studies reaffirmed many sexual stereotypes about men and women. On the other hand, some of these stereotypes were contradicted. When examining the most frequently cited reasons for having sex, men and women were remarkably similar in the 20 of the top 25 reasons given were identical for men and women.
Men showed significantly greater endorsement of having sex due to physical reasons, such as â€˜â€˜The person had a desirable bodyâ€™â€™; â€˜â€˜The person was too â€˜â€˜hotâ€™â€™ (sexy) to resist,â€™â€™ and simply because the opportunity presented itself: â€˜â€˜The person was availableâ€™â€™; â€˜â€˜The person had too much to drink and I was able to take advantage of them.â€™â€™ Men exceeded women on many items that pertained to physical pleasure such as, â€˜â€˜I wanted to achieve an orgasm,â€™â€™ and â€˜â€˜It feels good.â€™â€™ Men more than women reported having sex as a way to improve their social status (e.g., â€˜â€˜I wanted to enhance my reputationâ€™â€™; â€˜â€˜I wanted to brag to my friends about my conquestsâ€™â€™) and their sexual experience (e.g., â€˜â€˜I needed another notch on my beltâ€™â€™; â€˜â€˜I wanted to improve my sexual skillsâ€™â€™). Finally, men exceeded women on endorsing a variety of utilitarian reasons for sex: â€˜â€˜I wanted to change the topic of conversationâ€™â€™; â€˜â€˜I wanted to improve my sexual skills.â€™â€™ Women exceeded men on only three of the 237 reasons: â€˜â€˜I wanted to feel feminineâ€™â€™; â€˜â€˜I wanted to express my love for the personâ€™â€™; â€˜â€˜I realized that I was in love.â€™â€™
Their findings contradict the stereotype that women, more than men, use sex to obtain special favors. In their study, men were more likely to endorse reasons for having sex that involved utilitarian goals (“To get a favor from someone”).
Below is a table that list nearly all of the 237 reasons Meston and Buss derived from their surveys. Along with each reason is the the category that that particular reason belongs to and the score for that reason (somply put the score refers to the commonality of that reason used between the sexes, please read the full report for a more precise understanding).[table “2” not found /]
However, in the end Meston and Buss conclude that:
All of these diverse theoretical perspectives, when taken together, point to a singular conclusion: The reasons people have sex are likely to be far more numerous and psychologically complex than previous taxonomists have envisioned.
There, they said it, you are complicated.
I Feel like there are already enough reasons to have sex. I mean after all, one is enough for me. But Dr. Buss and Dr. Meston are working on a new project: a list of reasons to say no to sex. If you want a chance to help out, interested participants are invited to fill out a questionnaire.
The paradox is this: Suppose a man traveled back in time and killed his biological grandfather before the latter met the traveler’s grandmother. As a result, one of the traveller’s parents and by extension, the traveler himself would never have been conceived. This would imply that he could not have traveled back in time after all, which in turn implies the grandfather would still be alive, and the traveler would have been conceived, allowing him to travel back in time and kill his grandfather. Thus each possibility seems to imply its own negation, a type of logical paradox. The grandfather paradox has been used to argue that backwards time travel must be impossible. However, other resolutions have also been advanced.
An equivalent paradox is known in philosophy as autoinfanticide â€” that is, going back in time and killing oneself as a baby â€” though when the word was first coined in a paper by Paul Horwich it was in the malformed version autofanticide.
The Mongolian Death Worm is a cryptid reported to exist in the Gobi Desert. It is generally considered a cryptozoological creature, one whose sightings and reports are disputed or unconfirmed. There are a number of extraordinary claims by Mongolian locals (such as the ability of the worm to spew forth a yellow poison that is lethal on contact, and its purported ability to kill at a distance by means of electric discharge). However, there are no known reliable sightings.
