An important revolution in absolute dating for human evolution research was the introduction of single-crystal 40Ar-39Ar dating. This modified method uses a very narrow laser to heat a single crystal within a sample in order to extract the argon isotopes for measurement and age calculation. This approach permits the researcher to identify and exclude contaminant grains from previous eruptions of different ages. Only crystals of the most recent eruption are included in the dating analysis.

Platonic relationships between close friends frequently involve flirtation, admiration, and commitment, but don’t indicate anything about any party’s sexual or romantic attraction or preferences.

The amount of light produced can be measured in a laboratory setting. Because this accumulation of trapped electrons begins with the formation of the crystal structure, thermoluminescence can date crystalline materials to when they formed or to the last time the materials were exposed to light. For ceramics this is either the moment they are fired or the last time the ceramics were exposed to the sun as they were buried, which can be distinguished by the degree of purge in the electron traps. Thermoluminescence is used to date crystalline minerals to the time of their last heating event in the past. This method is useful for ceramics (pottery) and sediments that were exposed to a very significant amount of sunlight. As radiation from the environment is constantly bombarding minerals, energized electrons start to become trapped within defects of the crystal lattice.

But to younger readers, it may be utterly foreign, antiquated and unrealistic—like viewing a scene from an old black-and-white film in a world accustomed to the rapid-fire images of a high-definition action movie.
