The Universal Hot/Crazy Matrix: A Man’s Guide to Women

Updated 8 January c Introduction In a related article on geologic ages Ages , we presented a chart with the various geologic eras and their ages. In a separate article Radiometric dating , we sketched in some technical detail how these dates are calculated using radiometric dating techniques. As we pointed out in these two articles, radiometric dates are based on known rates of radioactivity, a phenomenon that is rooted in fundamental laws of physics and follows simple mathematical formulas. Dating schemes based on rates of radioactivity have been refined and scrutinized for several decades. The latest high-tech equipment permits reliable results to be obtained even with microscopic samples. Radiometric dating is self-checking, because the data after certain preliminary calculations are made are fitted to a straight line an “isochron” by means of standard linear regression methods of statistics. The slope of the line determines the date, and the closeness of fit is a measure of the statistical reliability of the resulting date. Technical details on how these dates are calculated are given in Radiometric dating. Here is one example of an isochron, based on measurements of basaltic meteorites in this case the resulting date is 4. Reliability of radiometric dating So, are radiometric methods foolproof?

So, how do we know how old a fossil is? There are two main methods determining a fossils age, relative dating and absolute dating. Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.

Relative Dating The majority of the time fossils are dated using relative dating techniques.

Dinosaurs disappeared about 65 million years ago. That corn cob found in an ancient Native American fire pit is 1, years old. How do scientists actually know these ages? Geologic age dating—assigning an age to materials—is an entire discipline of its own. In a way this field, called geochronology, is some of the purest detective work earth scientists do.

There are two basic approaches: Here is an easy-to understand analogy for your students: Absolute age dating is like saying you are 15 years old and your grandfather is 77 years old. To determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones.

This is called the Rule of Superposition. This rule is common sense, but it serves as a powerful reference point. Geologists draw on it and other basic principles http: Relative age dating also means paying attention to crosscutting relationships. Say for example that a volcanic dike, or a fault, cuts across several sedimentary layers, or maybe through another volcanic rock type.

Contact Us To trace the history of cross stitch, we must look back to the very beginnings of embroidery, since it is only relatively recently that cross stitch has been used as the sole stitch in a piece. Ancient wall paintings and sculptures show that embroidery was worked on clothing from the earliest times. An ancient Peruvian running-stitch sampler has been dated to — AD The word Embroidery comes from the Anglo-Saxon word for “edge”, but the technique itself was being used long before that.

The term was first applied to decoratively stitched borders on medieval church vestments. But over time it came to cover all stitched decoration on any textile fabric.

In other words, if an edge that is in and is not in is added to , it would cause to no longer be a matching graph, as a node will have more than one edge incident to it. Note that a maximal matching is not necessarily the subgraph that provides the maximum number of matches possible within a graph. Maximal matchings shown by the subgraph of red edges. Simply stated, a maximum matching is the maximal matching with the maximum number of edges.

Every maximum matching is maximal, but not every maximal matching is a maximum matching. In weighted graphs, sometimes it is useful to find a matching that maximizes the weight. A group of students are being paired up as partners for a science project. Each student has determined his or her preference list for partners, ranking each classmate with a number indicating preference, where 20 is the highest ranking one can give a best friend, and rankings cannot be repeated as there are 21 students total.

For most of those players, such an opportunity is still likely to emerge. With the announcement on Friday, however, that Alcides Escobar would be returning to the Royals, the future for one of them has become less certain. Since December 15th alone, the club has traded away left-hander Matt Moore , a general disappointment in the innings he had thrown for the Giants. They followed this up by acquiring two faces of their former franchises: Or so it seemed.

Giants president of baseball operations Brian Sabean seemed to suggest otherwise recently, according to reports by Alex Pavlovic and John Shea. Even though he was an effective player from to , he turns 31 in a week and hit the disabled list twice last season. Jackson might be best relied on as a part-time player, albeit a very good one. So were does that leave the Giants? They seem to be keeping an eye on the market for outfielders, probably with a view towards acquiring a cheap option somewhere along the line.

The stigma is beginning to dissipate as an increasing amount of Americans believe that online dating is now socially acceptable. During an April survey, 84 percent of dating app users stated that they were using online dating services to look for a romantic relationship. A further 43 percent used online dating for friendly contact and only 24 percent of respondents stated that that they used online dating apps and services explicitly for sexual encounters.

The same survey also found that there were more male internet users who were currently using dating sites or apps than female users. Dating sites and apps were most popular among younger internet users – 30 percent of U. Current online dating site users explained their reasons for using online dating sites or apps with answers that included finding someone for a long term relationship or even marriage and the chance to meet people who just want to have fun.

These chart types include line charts, bar charts, candlestick charts, and point and figure charts. Line Charts Line charts are the most basic type of chart because it represents only the closing prices over a set period. The line is formed by connecting the closing prices for each period over the timeframe. Figure 11 — Line Chart Example — Source: The chart is made up of a series of vertical lines that represent the price range for a given period with a horizontal dash on each side that represents the open and closing prices.

The opening price is the horizontal dash on the left side of the horizontal line and the closing price is located on the right side of the line. If the opening price is lower than the closing price, the line is often shaded black to represent a rising period. The opposite is true for a falling period, which is represented by a red shade.

Figure 12 — Bar Chart Example — Source: The difference is a wider bar or rectangle that represents the difference between the opening and closing prices. Falling periods will typically have a red or black candlestick body, while rising periods will have a white or clear candlestick body. Days where the open and closing prices are the same will not have any wide body or rectangle at all.
