issues in pregnancy dating revisiting the evidence-7

Last month, in , Matthew Hutson wrote a fascinating article, “The Science of Superstition: No One Is Immune to Magical Thinking.” Actually as an article it’s really not that fascinating, but as an illustration of the mental contortions one must make to defend atheism, it is Olympic.Hutson cited a number of studies that demonstrated that “…even physicists, chemists and geologists at MIT and other elite schools were instinctively inclined to attach a purpose to natural events.” Hutson illustrates the point through research that subjected scientists to time pressure, thereby getting a more honest, reflexive response to questions rather than a response filtered through reflection and vetted for consistency with conscious beliefs.

Determining an Estimated Date of Delivery by ultrasound in the first trimester It is possible to become pregnant even though a woman has not had a period for a long period of time.The longest resident of death row in Texas, Raymond Riles, has been sitting in solitary confinement (except for doctor visits and court appearances) since February 1976.Since the reinstatement of the death penalty in 1976, 41 inmates on death row have died either of natural causes or suicide while awaiting execution.The fertilization age (also called embryonic age and later fetal age) is the time from the fertilization.It usually occurs within a day of ovulation, which, in turn, occurs on average 14.6 days after the beginning of the preceding menstruation (LMP).Roughly 13 % (30 of 238) of the inmates awaiting execution in the Lone Star State have been on death row for 25 years or more.

That length of stay is nearly a decade above the national average time awaiting execution of 15 years and 9 months.

There is also considerable variability in this interval, with a 95% prediction interval of the ovulation of 9 to 20 days after menstruation even for an average woman who has a mean LMP-to-ovulation time of 14.6.

The actual variability between gestational age as estimated from the beginning of the last menstrual period (without the use of any additional method mentioned in previous section) is substantially larger because of uncertainty which menstrual cycle gave rise to the pregnancy.

If you are unsure of when the first day of your last period was, don’t worry.

An ultrasound can be performed to determine gestational age (how many weeks into the pregnancy you are).

For Hutson this demonstrates the persistence of “magical thinking.” Here were scientists, most of whom were decidedly non-religious, assenting to statements that implied an architectonic and therefore religious framework.
