Science dating

When it comes to determining the age of stuff scientists dig out of the ground, whether fossil or artifact, “there are good dates and bad dates and ugly dates,” says paleoanthropologist John Shea of Stony Brook University.

Overwhelmingly, the women preferred the odors of men with the most dissimilar MHCs to their own (see: adjacent video).

Biostratigraphy: One of the first and most basic scientific dating methods is also one of the easiest to understand.

Layers of rock build one atop another — find a fossil or artifact in one layer, and you can reasonably assume it’s older than anything above it.

“Science is often presented as something that is ‘other,’ that it is for only certain types of people,” says Olivia Koski, operations director for Guerilla Science. Human beings are scientists from birth, in the sense that we all have a curiosity to explore the world around us and learn from our experiences.” Koski and her colleagues at Guerilla Science have been experimenting with this concept in the U. Past events have included “The Science of Disco,” which provided insight into how our brains behave when we dance, and “The Fire Organ,” featuring a huge, unorthodox pipe organ that uses flames to reveal the shapes of sound waves.

At Mysteryland, participants could play the Fire Organ and participate in the “Flavor Feast,” a series of taste-based experiments designed to disrupt expectations about certain foods.

Sometimes only one method is possible, reducing the confidence researchers have in the results. “They’re based on ‘it’s that old because I say so,’ a popular approach by some of my older colleagues,” says Shea, laughing, “though I find I like it myself as I get more gray hair.” Kidding aside, dating a find is crucial for understanding its significance and relation to other fossils or artifacts.
