What happens when something reaches absolute zero? At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. Thus, nothing can be colder than absolute zero on the Kelvin scale. Physicists have now created an atomic gas in the laboratory that nonetheless has negative Kelvin values. What determines the state of […]

How many horsepower is a human? 1.2 hp Why does a horse have 15 horsepower? While it is true that the maximum output of a horse is around 15 horsepower, when you average the output of a horse over the course of a work day it ends up being around a horsepower. Watt defined this […]

The role of the dermis is to support and protect the skin and deeper layers, assist in thermoregulation, and aid in sensation. What are […]

What do you notice about the iron filings? All magnets show properties of magnetic attraction and repulsion. With the use of iron filings, we can see these magnetic fields. When iron filings are sprinkled on a bar magnet, you see that these magnetic field lines start at the magnet’s north end and will end at […]

How might predator/prey relationships affect light pollution? Summary: A new study provides strong evidence that exposure to light pollution alters predator-prey dynamics between mule deer and cougars across the intermountain West, a rapidly growing region where nighttime skyglow is an increasing environmental disturbance. When the environment has reached its carrying capacity for the human population […]

How much does the moon move at night? Each night, it moves about 13 degrees, or about 26 diameters, to the east. The apparent motion of the Moon from hour to hour; each hour it moves about one diameter to the East. Why do I feel spiritually connected to the moon? The moon has been […]

Do electrons move in their orbitals? Because an electron is a quantum object with wave-like properties, it must always be vibrating at some frequency. Furthermore, an electron in a stable atomic state does not move in the sense of waving through space. The orbital electron does move in the sense of vibrating in time. Can […]
