Editing Talk:1512: Horoscopes

So funny - especially the title text made me laugh :-) --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 07:05, 15 April 2015 (UTC)
:Nine months later, it would certainly eliminate the stress of wondering if you were gonna "get lucky" that night. - Equinox [[Special:Contributions/199.27.128.120|199.27.128.120]] 16:13, 15 April 2015 (UTC)

The "coriolis effect" in the title text refers to the spin direction of vortices (rotating currents such as cyclones, whirlpools, and water draining from a basin), which is counter-clockwise in the northern hemisphere and clockwise in the southern hemisphere.  The title text is a joke extending the reversal to the flow of time.

If the baby is born 9 months BEFORE they're conceived, would that account for the shift in seasons for the southern hemisphere? Born in March: Northern hemisphere -> conceived in June; Southern hemisphere -> conceived in December. June and December being summer respectively. If that's right, could someone add that to the wiki? [[User:none]]

The events described during which the conception of a person with a given birth month occurred assumes that the parents were in the United States at that time.  The seasons would be shifted by six months in the southern hemisphere, and the holidays of the 4th of July (Independence Day -- Aries), Halloween (Cancer, conception in October), Thanksgiving (Leo, conception in November), Mother's Day (Aquarius, conception in May), and the NCAA (college) basketball playoffs ("March Madness" -- Sagittarius) , might either not be celebrated or celebrated on a different day.

:Halloween is starting to become common in Brazil, including the "Trick or Treat" stuff. Mother's Day is also celebrated at the same date. And I wouldn't be surprised if Thanksgiving became common here too, if not only for the sales... [[Special:Contributions/188.114.97.151|188.114.97.151]] 19:47, 17 December 2015 (UTC)

"Today, horoscopes are admitted to be pseudoscience." Citation needed. But what rubbish. Horoscopes are not even pseudoscience, so who is it "admitting" they are? [[Special:Contributions/108.162.250.187|108.162.250.187]] 08:36, 15 April 2015 (UTC)

:Agree, I would like the citation for "today", as there were experiments disproving horoscopes in ancient Rome already (involving two babies born in same time, one rich, one slave). -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 12:48, 15 April 2015 (UTC)

The general trick to horoscopes is make them vague enough that anyone can think they're true, regardless of their sign. --[[User:PsyMar|PsyMar]] ([[User talk:PsyMar|talk]]) 10:34, 15 April 2015 (UTC)

I propose an addition to the "conceived during someone's wedding" -- it's more common that the conception is actually after the wedding, during the (somewhat expected) consummation by the actual married couple.  Thus, "honeymoon babies"! --BigMal // [[Special:Contributions/108.162.221.181|108.162.221.181]] 12:53, 15 April 2015 (UTC)

The expected conception column is off, therefore the explanations may be off. Length of a human pregnancy is 38 weeks after conception, or 9 1/2 months, not the 9 months that is commonly portrayed. I'm not sure if Randall took this into account or not. [[Special:Contributions/199.27.133.121|199.27.133.121]] 20:40, 15 April 2015 (UTC)
:This is true, except you must have meant 8½ month not 9½ since 38 weeks is less than 9 month. Actually it is very close to 8,75 month. But anyway you are correct, that all the dates should be fixed to go 38 weeks back, not 9 months!--[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 20:54, 15 April 2015 (UTC)

::::Even 38 weeks is idealised - I have a niece and nephew who were born 22 weeks after conception (4 years old now and doing well!)  And term isn't until 41 weeks (from last menstruation) in France.  38 weeks happens to be a useful average in many parts of the world, but even healthy term pregnancies in USA/UK/Australia(/others?) covers the range of 35-40 weeks from conception.  Also, with the rise of babies conceived by IVF, it's no longer quite so obvious what was happening 38-ish weeks before birth!

No reference to the fact that November babies might be conceived on V day? [[User:Vkapadia|Vkapadia]] ([[User talk:Vkapadia|talk]]) 21:10, 15 April 2015 (UTC)
:V-E day is not celebrated in the U.S. It has far less historical significance to us, since to us it was just an important date in the middle of a war. So the holidays that were included (like July 4 and October 31) make more sense in the U.S. for conception dates, even if they mean nothing internationally.

In the second paragraph of the explanation, can we use either "i.e." or "for example," but not both? I don't have a particular preference for one or another; anyone who does is encouraged to make the correction. [[Special:Contributions/173.245.50.125|173.245.50.125]] 06:32, 17 April 2015 (UTC)

Regarding about Gemini, which coincidentally I am one, doesn't apply to South-East Asian countries like Singapore(where I am born in), where the leaves doesn't change colors the whole year round. Same goes to the rest of the horoscopes as well. Boeing-787lover 13:56, 30 November 2017 (UTC)

Aries and to a lesser extent Cancer: kids went back to school, leaving house empty, or if your parents are in education (incl. college) they'd just started a new semester and met a bunch of new people.

== Gestation period ==

The accepted length of a pregnancy in the U.S. is 38 weeks, but this is not true everywhere. In France, for instance, the term is 41 weeks. Both of these are just traditional and not based on precise data. A good study to look to here is Jukic, Baird, Weinberg, McConnaughey, and Wilcox "Length of human pregnancy and contributors to its natural variation." This study is a very belated 2010 follow-up on a 1985 study on the rate of early pregnancy loss by Wilcox et al. They recruited women who had just ceased birth control because they intended to become pregnant. Although the study doesn't specify, they presumably had sex almost ever night, and according to the follow-up, urine samples were collected EVERY MORNING. These samples were tested for the presence of human chorionic gonadotropin (hCG), and if it was present above the threshold, the women were determined to be pregnant. Not much analysis was done on the question of how long after implantation it takes for hCG levels to rise above that threshold, but my tiny modicum of biological understanding suggests it should be hardly any time at all. The original study used this early-pregnancy data to measure the rate of loss of the fetus very early in pregnancy, controversially finding it to be around 30%.

The follow-up had a different goal. It re-contacted those same women and managed to recruit most (though not all) into a new survey. The goal was to determine which of these women had artificially shortened their pregnancies through cesarean sections or other methods in order to exclude them from the analysis (with measures taken to account for the biases this introduces). The women who were not excluded numbered 120 and had a (corrected) median gestational time (from ovulation to birth) of 38 weeks 2 days. But what is more interesting is that even after excluding premature outliers, this sample of 120 women had a range of 37 days. That means the earliest non-excluded birth was 37 days before the latest birth.

I think this explains why there is so much variation in how different countries treat births and why we never get a precise figure. Even within a single population of women (I think from around North Carolina? They don't say), the range of outcomes is enormous. Still, I think this is strong evidence that the average gestational period is closer to 38 weeks than to 40 weeks (or 41, as the French would have it). But at any rate, I imagine the magic number Randall had in mind was 9 months, figured as 3/4 of a year (i.e. about 274 days, or 39 weeks 1 day).
