I'd vote for Mathematicians if they were included.

It's called a search algorithm, and we do it every time we open a book, most obviously, a dictionary, but also textbooks. Flipping pages is an extremely simple yet inefficient algorithm, and your example shows "flipping pages" only at the end where the possibilities have dwindled to a handful. With electronic systems, binary searches are used, and I've also read where the Golden Ratio (using 0.618033... instead of 0.5 in binary searches) can be more efficient. Generally speaking, there's also various methods such as hash functions and sorting algorithms used for categorizing/sorting/storing/searching for data. Alphabetization is a very common sorting algorithm, classically used in dictionaries, filing cabinets, computers (lists of file names), etc. I wonder if using the Golden Ratio improves efficiency due to Benford's Law.

One prominent idea is that the "secondary sex ratio" of 105 (ie, 105 males to 100 females) at birth drops to a "tertiary sex ratio" of ~100 (ie, 1:1) during the childing bearing years due to the higher mortality rate for males than for females, even in infancy (ie, seemingly before boys become more rambunctious than girls). The theory pointing toward the target of 1:1 during child bearing years is further supported by the fact that the "primary sex ratio" at conception is even more skewed in favor of males than is the secondary sex ratio (I have seen studies stating that it is 115, 138, and higher) supposedly due to more males suffering spontaneous abortions, stillbirths, etc. It's tough being male! This pdf from the University of Idaho is interesting, and it also touches on why females live longer. Only where overall life expectancy (ie, males and females combined) drops below ~45 years (ie, in Afghanistan and some African countries), do males outlive females (and then, not by much ... ~1 year).

I'm not dissing you (I also might get weirded out if the same thing happened to me), but objectively, I would tend to think that the cause-and-effect are the other way around. You knew wasps frequented where you hunt mushrooms, or you knew it was wasp season, or you (unconsciously?) overheard talk about someone getting stung by a wasp, or someone mentioned wasps recently. Knowing that you planned to go into the "wilds" to hunt mushrooms the next day, wasps were "on your mind", and so, you dreamed about one. If you had dreamed about seeing a bat in the middle of the day or about problems with your computer, then the memory of it would have been unremarkable and forgotten, and you would not perceive a pattern. I think our sleeping brains mull over many unresolved issues. Consider Michael Shermer's The pattern behind self-deception about so-called "patternicity" and perceiving false patterns.

I simply went to my thesaurus and found this — LAW implies an exact formulation of the principle operating in a sequence of events in nature, observed to occur with unvarying uniformity under the same conditions THEORY, as compared here, implies considerable evidence in support of a formulated general principle explaining the operation of certain phenomena HYPOTHESIS implies an inadequacy of evidence in support of an explanation that is tentatively inferred, often as a basis for further experimentation

if there is no life after death does anything matter at all?
ewmon replied to dragonstar57's topic in General Philosophy
The OP's question is: Once a person's life ends, the general idea of an afterlife is that the person has no control over the consequences of an afterlife (even if it involves reincarnation), which are rather absolute (some "supreme being" makes a judgment and pronounces sentence). When people no longer believe in an afterlife (ie, the ultimate consequences over which they have no control), then living in the present tends to become self-serving and relative. To answer the OP's question, "Does anything matter at all?", my answer was that it has even come to female teachers, to whom we could undoubtedly entrust our children, can no longer be trusted as much as they used to be. These people are an excellent example of what happens when one does not believe in an afterlife. This is, after all, what we're talking about. To some people, life will continue to have some sort of meaning; to others, the meaning of life will become very self-serving and relative. See it, want it, take it. I merely gave shocking real-life examples. -
Justice as a whole is composed of several basic forms of justice, one of them being "restorative justice" — remedying an offense — through revenge, forgiveness, restitution or compensation. Revenge consists of causing harm, pain or suffering to counter a wrong. It probably comes from basic human emotions, and it typically follows contemplation of the original harm, and it usually involves severe anger with the intent to restore a victim’s damaged social status (even if such restoration is not real, but only imagined by the victim). Revenge often causes psychological harm to the victim as well as harming the offender. People typically consider it wrong because it often involves suppressed anger, which can cause psychological problems for the victim. Revenge is criticized because it typically doesn’t do what it was meant to achieve, and it can escalate into a quid pro quo situation. Forgiveness, as with revenge, attempts to cope in response to perceived injustice. In contrast to revenge, forgiveness does not demand the offender to compensate the victim for the injustice inflicted. Forgiveness comes from a totally different perspective and results in a totally different conclusion. It is a mental, emotional and physical resolution to abandon all anger and, instead, to act with love and acceptance. Forgiveness is typically looked upon a religious act; however, parents teach it to their children, adults tend to encourage each other to forgive, and dying people make acts of forgiveness. In forgiveness, the victim purposely relinquishes revenge and punishment and may free the offender from obligations to return or compensate the victim for what was taken, damaged or destroyed — often something that is impossible to do anyway.

Correlated with history means that, before circa 2000, hardly a case of female teachers having sex with their students can be found. I can't cite the absence of cases. Perhaps Pamela Smart in 1990 was the seminal case of female-teacher-and-student sex (and more). Regarding the overall increase in serious female-perpetrated crimes, there's the case of Wanda Holloway (1991), a Texas mother who attempted to murder the mother of her daughter's cheerleader rival so her daughter would make the squad. There's the Tonya Harding case (1994) who hired thugs to literally knock rival figure skating champion Nancy Kerrigan out of the competition. And then, in 2000, there's the Katherine Knight case (who, I'll grant, is insane) who murdered, skinned, butchered, cooked, and ate her husband and tried to serve his cooked remains to his children. Ms Knight gets the blue ribbon for that one. Lizzie Borden (1892) was the former big, bad "bogeywoman" in American folklore, but she can no longer hold a candle to these criminals. Also in 1990, the tragic childhood of Richard Berendzen, then-president of American University in Baltimore, came to light after he was caught making indecent phone calls. As the case unfolded, it was found that his mother had forced him to have sex with her during his young boyhood in the 1940s. He detailed this horrific abuse in his book, Come Here, so entitled because that's how she would call him when she wanted to have sex with him. Blame. Is the emergence of 233 cases of female-teacher-and-student sex in the last 5 or 10 years a bizarre coincidence, or the result of a permissive attitude in our society, or copycat crimes, etc? Even if they are copycat crimes, they were made all the more possible by society's permissive attitude. Citations. I cited an article detailing 233 cases of female-teacher-and-student sex in the last 5 or 10 years. I could have written to the relaxed standard of other posters in this thread, and yet, I gave a citation. If this thread requires citations, here are two instances that lack citations: This material is getting off topic, which was never my intention, so I will leave it. -

Yes, specifically female teachers have sex with their students. Correlated with history. Circa 2000. Women and teachers are some of the most trusted members of our society when it comes to the welfare of our children ... well ... they used to be. -

It's all eat, drink and be merry for tomorrow we die, just like Jay in the movie Dogma. When there's no consequences -- no afterlife -- after someone takes a "dirt nap", then there's no ultimate punishment ... hey, it's all over when we die. We'd be no better than animals. Look at these 233 pleasure-seeking (and supposedly upstanding) citizens who made the big list recently. This is society gone wrong in a big way --- not 233+ coincidences. -
This is a difficult proposition. We're talking about releasing horrific amounts of energy with broad-reaching destruction and consequences that if, for example, they had been able to "burp" Mount St Helens, would the result have been worse than if they let it take it's natural course? There's never any "do over" or side-by-side comparison, so it'll be hard to say if intervening was better or worse. Burping a volcano or releasing pent up earthquake energy is a human-orchestrated event, not a natural catastrophe, so there's legal consequences as a man-made disaster instead of an "act of God". Think of the hoopla if Iceland had decided to "burp" their volcano ... such international, commercial and social consequences.

High altitude flying conserves fuel and helps avoid adverse weather/turbulence. ...and then there's the aircraft's maximum pressure differential between cabin and atmosphere that must not be exceeded, otherwise the hull might rupture.

1) The 4V battery would run current backwards through the 2V battery. The initial voltage of the this parallel arrangement will be 4V. 2.1) The currents add in parallel arrangements of identical batteries because Kirchhoff's Current Law says the currents flowing out of a node equals the currents flowing into it. 2.2) The current flowing through the circuit (including the battery pack) equals the battery pack's voltage divided by the total resistance of the circuit (including the resistance of the battery pack of 0.5 ohms). Due to the parallel arrangement and Kirchhoff's Current Law, the current splits equally among the batteries, thus each battery experiences half the circuit's current.

25. The reaction: 2·H2O —► 2·H2 + O2 using 12.2 g of water a. What is the definition of a “mole”? b. How many moles of water are in the problem? c. What's the ratio of hydrogen gas molecules produced per water molecule? d. How many moles of hydrogen gas are produced? (This thought sequence will help to prepare you for #26)

Are we assuming that we peer into space along a straight line? Could it be an optical illusion? -
This sounds like homework. Tell us what have you done so far? Tell us what you know about Cr(NO3)3?

The music and scenery was very pretty. I hope they computed the reaction of the platform to the rocket thrust. And the platform serves what purpose (instead of simply hanging the rocket from the balloon)?

I've found psychology and psychiatry to involve inordinate amounts of creativity and freedom ... and practitioners can vary the speed of patient recovery depending on whether the economy is good or bad or whether you want an in-ground pool, vacation in Europe, etc. No clinical tests or independent sources exist to determine how well or poor a job the practitioners perform. Am I being too cynical?

China has problems too, a couple of days-long dozens-of-miles-long traffic jams this summer just a week apart. I try very hard to stay away from limited-access highways.

Welding supplies? I saw a welder using a small slab of it about 8 inches square, maybe ½–¾ inches thick. They might have an odd chunk of it around that they have no use for.
