Our ancestors got less food, got more exercise and lived shorter lives. This probably wasn't a problem for them.

I tihnk you've made a communication mistake. You dispute that they occupied the northest, then propose that they occupied the northeast. The Wikipedia articles assign gray wolf as Canis lupus, and red wolf alternately as Canis rufus or Canis lupus rufus. Maybe their status as a subspecies of Canis lupus is disputed, in which case there may still be gene flow between the populations. Alternatively, the common name "red wolf" might not denote an evolutionary clade - common names aren't assigned by scientists and aren't used in any precise manner.

is astrology really a pseudoscience? [yes]
MonDie replied to ark200's topic in Astronomy and Cosmology
Astrology doesn't utilize the physical sciences to formulate hypotheses, and astrologers can't even agree amongst themselves. Some are tradional hellenistic or Vedic types, while others dig the "psychological" astrology we know today. Still others like to use miniscule asteroids, dwarves, or even mathematically derived points like "Lilith" (the lunar apogee). Some divide the circle endlessly into smaller and smaller "aspects". The "esoteric" astrologers give different interpretations for even the traditional inner planets. Others do heliocentric astrology, or use right ascension instead of ecliptic longitude. They often use a multitude of charts: the natal, transits, and secondary or tertiary progressions, etc.. (It's been years now, but I still deeply regret all the time I wasted. ) The variations are endless, yet they haven't even given a satisfactory verification of the claims they do agree on. You're bound to find some weak links if you look hard enough, but astrology can't be considered a distinct area of inquiry. A study on rats suggested a potential effect of the perinatal photoperiod on behavioral differences. Perinatal photoperiod imprints the circadian clock (Ciarleglio, Axley, Strauss, Gamble, McMahon, 2010) Who knows what else might cause some correlations. Seasonal depression will affect people's sex drives to varying degrees. The seasonal availability of crops might effect the health of the fetus. I wouldn't call any of this "astrology" though. Biology, pscyhology, or sociology would be preferable labels. The only person I know to have proposed a totally original physical explanation was Michel Gauquelin, but his ideas were never accepted by the scientific community. (He also had his own idiosyncratic style of astrology, by the way). In short, yes it is a pseudoscience, a non-science that pretends to be a science. -
perihelion & lowest light-time don't coincide
MonDie replied to MonDie's topic in Astronomy and Cosmology
The full moon was about nooonish (UTC/GMT) on January 3rd, the day preceding. Looks good, Janus. -
perihelion & lowest light-time don't coincide
MonDie replied to MonDie's topic in Astronomy and Cosmology
The Horizons interface isn't work from this platform, or they changed something. Janus, I considered your response. I've never studied astronomy heavily, and I'm not sure whether to expect a preceding full moon or a succeeding full moon. I expect that the orbital calculation would be simplest tracing the earth-moon barycenter, but this is the three-body problem after all. If I'm right, the full moon should push the earth out toward the sun, causing the lowest light-time to fall somewhere between perihelion and the full moon. Given that the lowest light-time preceded perihelion, I would expect a preceding full moon. Did the full moon precede perihelion? I can't check. I thought the date would be implied since I was posting on the day of the event, excluding the timezones where it was about bed-time anyway. -
That was excellent, Sensei. (Also, Strange's link helped me understand it.) On a forum, it's hard to distinguish someone whose native language is not English from someone who is very young or is autistic.

Sensei, you point me toward useful concepts, but you would be noticeably more helpful if you elaborated more in your sentences, particularly if you elaborated on terms (f.e. "block of data") or used more standardized terms. In fact, sometimes just saying "Look up terms xxx and yyy" can be more useful than giving your own unprofessional account. Although in the case of programming, one can also benefit greatly from examples of code. What meaning of "efficiency" would be distinct from CPU execution time? That's odd. Is it perchance less efficient because non-standard objects, such as masks, result in messier code and thus messier binary code?

Phenotypic Plasticity and Speciation
MonDie replied to starlarvae's topic in Evolution, Morphology and Exobiology
Perhaps the problem is that, although Canis lupus has enough variation to speciate, we can't know whether it will ultimately end up speciating or converging back together. Just as a hybrid zone may lead to further reproductive isolation, or to a repooling of gene pools. Starlarvae, it's not clear (to me) that the scenario for Canis lupus would ever occur in the wild. Reproductive isolation is often naturally selected, so it may not happen for a domesticated species, especially one that is intentionally bred for greater variety. -
Okay, yeah. I just compiled a very simple program (below), and it was already more than 8 kilobytes. #include <iostream> int main() { } Then used linux's hexdump utility to output the binary of the executable, directing the output into a plain text file on my desktop. hexdump ./executable >~/Desktop/file It was a 470 by 9 grid of hexadecimals.

Perhaps the question is better rephrased to : Why are objects always byte-sized (multiples of 8, where 8 bits = 1 byte)? Couldn't you make more efficient programs if a 3 bit type were available, for example? Does the obejct (the binary sequence representing variable info, that is) also have to store the name of the variable in addition to its value? But couldn't restrictions be placed on name-sizes, forcing the programmer to rely on re-initialization rather than the creation of independent objects with unique names? Where do objects with no further importance go to anyway? Would a preference for re-initialization (or re-assignment?) result in smaller object files?

Your description of Darwin's style seems to resemble your own style. You're collecting little tidbits about his study habits, tidbits of which the usefulness isn't immediately obvious. Are you hoping to synthesize a more general conception of creativity? Then again, the passive absorption of details is prone to certain errors which formal analysis is not prone to.

I'm betting Windows is the problem here. I wouldn't put it past Microsoft to give Windows limitations in what file system types it can work with. I just opened GParted on Ubuntu to see all the types of file systems that it can write: btrfs exfat ex2 ex3 ex4 f2fs fat16 fat32 hfs hfs+ jfs linux-swap lvm2 pv nilfs2 ntfs reiser4 reiserfs ufs xfs cleared unformatted Windows, or at least the newer releases, can read fat32. Fat32 is pretty standard, so the file system probably wasn't the problem.

Phenotypic Plasticity and Speciation
MonDie replied to starlarvae's topic in Evolution, Morphology and Exobiology
I've wondered whether larger populations evolve more quickly, and whether evolution might accelerate when periods of amplified reproduction and diversity are puncuated by bottlenecks, as opposed to a stable but small population. Regardless, starlarvae may be hastily generalizing / inducting. Although it's uncommon (how uncommon?), a hybrid zone is an overlap between the territories of two diverging or recently diverged populations, and it shows that nature can produce sufficient variation for speciation. However, because these hybrids may have reduced viability or no viability, individuals who prefer members of their own population may be more successful. Hence reproductive isolation may be a natural, negative-feedback response to hybrid zones. -
Why women are so extremely emotional?

I for one enjoy being emotional. -
Why Human Blood looks very dark red compare to Animals?
MonDie replied to Ganesh Ujwal's topic in Biology
Wouldn't that depend on whether we're talking pulmonary or systemic? pulmonary arteries - deoxygenated, darker - - oxygenated by lungs pulmonary veins - oxygenated, brighter systemic arteries - oxygenated, brighter - - deoxygenated at capillary beds systemic veins - deoxygenated, darker - - cycle begins anew -
Is it necessary to make "life" and "human" into countable nouns? I am a human organism with a human heart and human brain. I developed from a human juvenile, which developed from a human fetus, from a human ovum, etc.

Okay, two questions. Can a C++ executable output the binary of a value? Why are all C++ objects at least 8 bits? Even bool, a binary true/false variable, usually occupies 8 bits (1 byte).

I'm sorry, John, but I'm done here—I'm done with the Philosophy section.

This really is a really good place to discuss science and math, which is why I came back, but the other forums are such a persistent distraction. For the rest of 2015, I will not post in any of the Philosophy or Other Topics sections aside from Speculations, Suggestions, and this thread. If I do, bring this thread back. Wow, I screw all the thread title semantics. I just got all hot and bothered when I realized that my other, isolated laptop lacked a C++ compiler.

So much for that. Bananas aren't made convenient artificially. The tree prepared the banana for you rather than a factory.

My understanding is that slander (or defamation) involves making false claims. Except it's not a murder trial, and the stakes aren't as high. This is civil court, I would think. We could apply to the innocence dilemma Stuart Mill's concept of civil liberty: My right to swing my fist ends at your nose. If the slanderer has swung their fist, then somebody must be guilty, and the question becomes whether the slanderer had sufficient justification to swing. However, we have to consider the confidence requirement of both claims: whether a fist was swung, and whether it was justified. Murder has a low base rate, so the claim of murder itself is evidence that a false claim was made (slander). However, evidence to the contrary, i.e. evidence that he didn't commit the murder in question, would strengthen our confidence that slander has occurred.

Would pseudoscience go in the Louge then? I actually have a collection of dates, stretching back some 4 or 5 years, that I began collecting in order to test a belief in divination that I held at that time. I wouldn't do it over again, but I have the data and now a better grasp of the math. I was thinking of discussing analysis in the Lounge rather than Speculations. At this point, the real aim is to expose my delusion and inquire into how it persisted.

Although it could vary between samples if it's due to environmental factors.
