Shop Now Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth. Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old. With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth. Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old. Basics Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry. Recall that atoms are the basic building blocks of matter. Atoms are made up of much smaller particles called protons, neutrons, and electrons. Protons and neutrons make up the center nucleus of the atom, and electrons form shells around the nucleus.
Measurement of N, the number of 14 C atoms currently in the sample, allows the calculation of t, the age of the sample, using the equation above. The above calculations make several assumptions, such as that the level of 14 C in the atmosphere has remained constant over time. The calculations involve several steps and include an intermediate value called the “radiocarbon age”, which is the age in “radiocarbon years” of the sample: Radiocarbon ages are still calculated using this half-life, and are known as “Conventional Radiocarbon Age”.
Since the calibration curve IntCal also reports past atmospheric 14 C concentration using this conventional age, any conventional ages calibrated against the IntCal curve will produce a correct calibrated age. When a date is quoted, the reader should be aware that if it is an uncalibrated date a term used for dates given in radiocarbon years it may differ substantially from the best estimate of the actual calendar date, both because it uses the wrong value for the half-life of 14 C, and because no correction calibration has been applied for the historical variation of 14 C in the atmosphere over time.

How to Succeed at Online Dating As life gets more hectic, more people are turning to online dating. Whether you use a dating app or a website or both , online dating for the first time can be overwhelming. This article features tips on how to create a profile that reflects your personality, how to search for people with common interests, and how to initiate conversations and in-person meetings. Be honest with yourself about the kind of person you’re looking for.
Don’t settle; however, understand that the saying you can’t judge a book by its cover can be very true. If you can’t find anyone interesting in the current profiles, understand that new ones appear daily on popular sites. Put up several recent photographs of yourself — in both indoor and outdoor light, also a variety of full body shots as well as close ups of your face.

After this defeat, the Romans undertook a comprehensive reform of their army and changed the basic tactical formation from the Greek-style phalanx armed with the hasta spear and the clipeus round shield to a more flexible three-line formation. The Hastati stood in the first line, the Principes in the second line and the Triarii at the third line. While the Triarii were still armed with the hasta, the Hastati and the Principes were rearmed with short swords and heavy javelins.
Each soldier from the Hastati and Principes lines carried two javelins. The iron shank was either socketed or, more usually, widened to a flat tang. A pilum usually weighed between two and four kilograms, with the versions produced during the Empire being somewhat lighter. Pictorial evidence suggests that some versions of the weapon were weighted with a lead ball at the base of the shank in order to increase penetrative power, but no archaeological specimens have been found.
Pila were sometimes referred to as javelins, but the archaic term for the javelin was verutum. From the third century BC, the Roman legion added a skirmisher type of soldier to its tactical formation. The Velites were light infantry armed with a short sword the gladius or pugio , a small round shield and several small javelins. These javelins were called veruta singular “verutum”.
The Velites typically drew near the enemy, hurled javelins against its formation and then retreated behind the legion’s heavier infantry. The Velites were considered highly effective in turning back war elephants , on account of discharging a hail of javelins at some range and not presenting a “block” that could be trampled on or otherwise smashed – unlike the close-order infantry behind them.
Controversy[ edit ] Anthropologist Helen Fisher in What happens in the dating world can reflect larger currents within popular culture. For example, when the book The Rules appeared, it touched off media controversy about how men and women should relate to each other, with different positions taken by New York Times columnist Maureen Dowd  and British writer Kira Cochrane of The Guardian. Sara McCorquodale suggests that women meeting strangers on dates meet initially in busy public places, share details of upcoming dates with friends or family so they know where they’ll be and who they’ll be with, avoid revealing one’s surname or address, and conducting searches on them on the Internet prior to the date.
Don’t leave drinks unattended; have an exit plan if things go badly; and ask a friend to call you on your cell phone an hour into the date to ask how it’s going. If you explain beautifully, a woman does not look to see whether you are handsome or not — but listens more, so you can win her heart.
