Alpha waves A healthy adult at rest is most likely to show an EEG pattern characterized by a high level of alpha waves.

Alpha waves are types of brain waves detected by using medical equipment such as magnetoencephalography (MEG) or electroencephalography (EEG), which measures the oscillation of electrical impulses in various sections on the scalp. Alpha waves usually come from the occipital lobe when the eyes are closed during wakeful relaxation such as when performing aerobic exercise. Alpha waves are minimized when sleeping or when the eyes are opened.  

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.
