Web Usability 4 Summary: Slow page rendering today is typically caused by server delays or overly fancy page widgets, not by big images. Users still hate slow sites and don’t hesitate telling us. Users really care about speed in interaction design. In , I wrote a column called ” The Need for Speed ,” pointing out how much users hated slow-loading web pages. Back then, big images were the main cause of response-time delays, and our guideline recommended that you keep images small. Today, most people in some countries have broadband, so you might think that download times are no longer a usability concern. And yes, actual image download is rarely an issue for today’s users though images can still cause delays on mobile devices. Still, response times are as relevant as ever. That’s because responsiveness is a basic user interface design rule that’s dictated by human needs, not by individual technologies.

Though they may know it as carbon dating or carbon 14 dating, there is an understood notion that when anything old is found, like an ancient artifact, it can be radiocarbon dated to find out exactly how old it is. Yet, as simple and straightforward as this seems, the process of dating objects via radiocarbon is far from simple and straightforward. Here I will present what radiocarbon is, the dating methods, the assumptions that govern them, and the known discrepancies that plague the method.
Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods. Some critics, particularly religious fundamentalists, argue that neither fossils nor dating can be trusted, and that their interpretations are better.
There are lots of ways to guesstimate ages, and geologists knew the earth was old a long time ago and I might add that they were mostly Christian creationist geologists. But they didn’t know how old. Radiometric dating actually allows the measurement of absolute ages, and so it is deadly to the argument that the earth cannot be more than 10, years old. Radiometric methods measure the time elapsed since the particular radiometric clock was reset.
Radiocarbon dating, which is probably best known in the general public, works only on things that were once alive and are now dead. It measures the time elapsed since death, but is limited in scale to no more than about 50, years ago. Generally applied to igneous rocks those of volcanic origin , they measure the time since the molten rock solidified. If that happens to be longer than 10, years, then the idea of a young-Earth is called into question.
If that happens to be billions of years, then the young-Earth is in big trouble. As of January, , The oldest rocks found on earth are 4. This is reported in the paper Priscoan 4. Williams; Contributions to Mineralogy and Petrology 1: The previous record was 3.
Online Dating: Good Thing or Bad Thing?
By Lorenzo Ligato Finding the right words to start a conversation can be hard, especially if you’re talking to a stranger on a dating app. The most successful openers, it turns out, are positive, thoughtful, creative and slightly personalized. That’s according to Hinge , a popular matchmaking service which connects users based on shared Facebook friends.
The report is the result of a month-long experiment, during which members of the Hinge team crafted over different openers and let a small portion of its users access them. Whenever the app matched those people with someone new, it sent them a prompt to use one of the conversation starters. The company then tracked what lines were sent most frequently and measured response rates to detect trends.

Incidence[ edit ] After the Kinsey Reports came out in the early s, findings suggested that historically and cross-culturally, extramarital sex has been a matter of regulation more than sex before marriage. For example, one study conducted by the University of Washington, Seattle found slightly, or significantly higher rates of infidelity for populations under 35, or older than Rates of infidelity among women are thought to increase with age.
In one study by Blow, rates were higher in more recent marriages, compared with previous generations. According to this theory, when people live within environments that are demanding and stressful, the need for bi-parental care is greater for increasing the survival of offspring. Correspondingly, monogamy and commitment are more commonplace. On the other hand, when people live within environments that encompass little stress and threats to the viability of offspring, the need for serious and committed relations is lowered and therefore promiscuity and infidelity are more common.
According to this theory, an area has a high sex ratio when there is a higher number of marriage-aged women to marriage-aged men and an area has a low sex ratio when there is more marriage-aged men to marriage-aged women. On the other hand, when sex ratios are low, promiscuity is less common because women are in demand and since they desire monogamy and commitment, in order for men to remain competitive in the pool of mates, they must respond to these desires.
Support for this theory comes from evidence showing higher divorce rates in countries with lower sex ratios and higher monogamy rates in countries with higher sex ratios. It is more common for men compared to women to engage in extradyadic relationships. In addition, recent research finds that differences in gender may possibly be explained by other mechanisms including power and sensations seeking. For example, one study found that some women in more financially independent and higher positions of power, were also more likely to be more unfaithful to their partners.
How Good Are Those Young-Earth Arguments?
The assumption that the geologic column is a base from which to calibrate the C dates is not wise. With a half-life of only years, carbon dating has nothing to do with dating the geological ages! Whether by sloppiness or gross ignorance, Dr.

The Radiometric Dating Game Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years.
We are told that these methods are accurate to a few percent, and that there are many different methods.
Background. Initially identified in , excavation at Area 15 of the Gault Site was undertaken to explore evidence of early cultures in Central ch focused on the manufacturing technologies, their relationship to Clovis, and the associated age of this assemblage.

Magnitudes and rates of change under different environmental scenarios The past is the key to the future Sea level rise to Modified from the IPCC sea level rise estimates from Wikimedia Commons and using estimates from Bamber and Aspinall , assuming a uniform rate of sea level rise. By examining how ice sheets responded to change in the past, glaciologists hope to uncover details that will help them understand how they are likely to change in the future.
By looking at how ice sheets changed over long timescales, they can extend the short observation period over the Antarctic Ice Sheet. For example, ice streams in Antarctica have been observed to change, accelerate, switch off and recede.
