It has been calculated that the largest heads weigh between 25 and 55 short tons 50 t. The heads were carved from single blocks or boulders of volcanic basalt, found in the Tuxtlas Mountains. The Tres Zapotes heads, for example, were sculpted from basalt found at the summit of Cerro el Vigia, at the western end of the Tuxtlas. The San Lorenzo and La Venta heads, on the other hand, were likely carved from the basalt of Cerro Cintepec, on the southeastern side, perhaps at the nearby Llano del Jicaro workshop, and dragged or floated to their final destination dozens of miles away.
It has been estimated that moving a colossal head required the efforts of 1, people for three to four months. It is known that some monuments, and at least two heads, were recycled or recarved, but it is not known whether this was simply due to the scarcity of stone or whether these actions had ritual or other connotations.

Posted on July 21, by The Physicist Physicist: When things die they stop getting new carbon and the carbon they have is free to radioactively decay without getting replaced. Carbon has a half-life of about 5, years, so if you find a body with half the carbon of a living body, then that somebody would have been pretty impressed by bronze. Of course none of that helps when it comes to pottery and tools except wooden tools. Generally speaking, archaeologists make the assumption that if the grains in and around of a clay pot are, say, 8, years old, then the pot itself is roughly the same age.
If you had an ancient amphora sitting around, would you use it for fresh strawberry preserves? And before you answer: A life spent potentially confusing future archaeologists is a life well spent. There are many different kinds of radiometric dating that are used to date things that are non-organic which is part of how we determine the age of the Earth. They each rely on a couple of different thoroughly verified principles.
First, that radioactive isotopes have a fixed half-life totally independent of their environment. And second, that the elements they were before and after the radioactive decay have different chemical properties. Impurities, such as dissolved air, are either forced out or concentrated in the last region to freeze. The same is true for any kind of crystal.

Some of the terminology is collector based, some is technical glassmaking jargon, some is a mixture of both, and some is of unknown origin. All pertain to and are useful for a full understanding of historic bottles. When directly quoted, the source of the definition or information is noted; otherwise the references are not typically noted.
This is particularly true if the definition is directly from John R. White’s work on bottle nomenclature published in Historical Archaeology, since this journal article is widely accepted and referenced by historic archaeologists. Not every term from his list is repeated on this list; only those deemed pertinent. The terminology and definitions here are a composite of information derived from an assortment of references, the most important of which include: Many other references were variably consulted also.

Scientific measurements such as radiometric dating use the natural radioactivity of certain elements found in rocks to help determine their age. Scientists also use direct evidence from observations of the rock layers themselves to help determine the relative age of rock layers. Specific rock formations are indicative of a particular type of environment existing when the rock was being formed.
For example, most limestones represent marine environments, whereas, sandstones with ripple marks might indicate a shoreline habitat or a riverbed. The study and comparison of exposed rock layers or strata in various parts of the earth led scientists in the early 19th century to propose that the rock layers could be correlated from place to place. Locally, physical characteristics of rocks can be compared and correlated.

History of ancient numeral systems Bones and other artifacts have been discovered with marks cut into them that many believe are tally marks. A tallying system has no concept of place value as in modern decimal notation , which limits its representation of large numbers. Nonetheless tallying systems are considered the first kind of abstract numeral system.
The number in Khmer numerals , from an inscription from AD. An early use of zero as a decimal figure. He gave rules of using zero with negative and positive numbers. Zero plus a positive number is the positive number and negative number plus zero is a negative number etc. The Brahmasphutasiddhanta is the earliest known text to treat zero as a number in its own right, rather than as simply a placeholder digit in representing another number as was done by the Babylonians or as a symbol for a lack of quantity as was done by Ptolemy and the Romans.
The use of 0 as a number should be distinguished from its use as a placeholder numeral in place-value systems.

How a 6-Year-Old Survived Being Lost in the Woods As a child, Cody Sheehy made headlines when he vanished into the freezing wilderness of Northeast Oregon, making it out safely after 18 hours of determined slogging. Retracing his steps 32 years later, Sheehy says that getting lost was one of the best life lessons he ever had. Cody, 39 years old and six foot two, grew up in a ranching family here in remote, rugged Wallowa County. When he was six years old—a mere 40 pounds and three and a half feet tall—he got lost in these woods while playing with his older sister during a springtime family picnic.
Within a few hours, a search party began looking for him, crisscrossing the Blue Mountains on horseback all night as rain fell and temperatures hovered just above freezing. They never found him. Instead, Cody, who is now a Tucson-based documentary filmmaker and sailor, found himself. Over 18 hours, he walked an estimated 14 to 20 miles out of the mountains and into the sparsely populated Wallowa Valley.
During that journey he fell into a river, climbed a tree to escape two terrifying coyotes, and hid from a passing car because—as he recalls it—his reptile brain had taken over. He was cold and exhausted, and he developed acute tendonitis in his ankles that put him on crutches for a week. But he saved himself.

Posted on May 29, by The Physicist Physicist: You personally define a set of directions forward, left, etc. Far more subtly, your perspective also includes time. A short, more pedantic answer is that the observer determines the coordinate system. You are at the origin center of a very particular, personal coordinate system. Philosophically interesting, but not useful.
Assure Widespread Adoption The focus of public health is on the health, safety and well-being of entire populations. A unique aspect of the field is that it strives to provide the maximum benefit for the largest number of people. Public health draws on a science base that is multi-disciplinary. It relies on knowledge from a broad range of disciplines including medicine, epidemiology, sociology, psychology, criminology, education, and economics.
The field also emphasizes input from diverse sectors including health, education, social services, justice, policy and the private sector. The public health approach is a four-step process that is rooted in the scientific method. It can be applied to violence and other health problems that affect populations. Grasping the magnitude of the problem involves analyzing data such as the number of violence-related behaviors, injuries, and deaths.
Data can demonstrate how frequently violence occurs, where it is occurs, trends, and who the victims and perpetrators are. These data can be obtained from police reports, medical examiner files, vital records, hospital charts, registries, population-based surveys, and other sources. Top of Page Step 2:

When we talk about types of relationships, we can mean that in at least two ways: The Nature of a Relationship While all relationships tell about the correspondence between two variables, there is a special type of relationship that holds that the two variables are not only in correspondence, but that one causes the other. This is the key distinction between a simple correlational relationship and a causal relationship.
A correlational relationship simply says that two things perform in a synchronized manner. For instance, there has often been talk of a relationship between ability in math and proficiency in music. In general people who are good in one may have a greater tendency to be good in the other; those who are poor in one may also tend to be poor in the other.

Tweet on Twitter The United States was over two years Abraham Lincoln issued the first official proclamation making Thanksgiving as a national holiday. As winds toward an end and our nation re-emerges from yet another hotly contested election cycle, politics is still far from over this year. But any unresolved political differences we now are facing pale in comparison to the headwinds facing Lincoln in November Even so, his proclamation is every bit as relevant then as it is today.
This is one of the greatest human achievements of our time. Unfortunately, our fixation on hyper-partisan political animosity leads us to believe that the opposite is true. But do our politics truly define us? I work in conservative Christian politics where I have to immerse myself in a litany of policy issues and voter education campaigns across the country, but my job and the amount of time I invest in politics does not define who I am.
First and foremost, I am a devout Christian. A father to two beautiful daughters. A son to two heroic parents who adopted me at birth. A brother and brother-in-law. None of us will ever agree on every political issue, but one thing all Americans can agree on is that we need to take the time to give thanks for our many blessings.
