Is stellar parallax true? Stellar parallax remains the standard for calibrating other measurement methods (see Cosmic distance ladder). Accurate calculations of distance based on stellar parallax require a measurement of the distance from Earth to the Sun, now known to exquisite accuracy based on radar reflection off the surfaces of planets. What is the cause […]
Will steroids help a bacterial infection?
Will steroids help a bacterial infection? Unlike the anabolic steroids used to bulk up muscle, corticosteroids are often used to treat inflammation related to infectious diseases, such as bacterial meningitis. Used against other infectious diseases, however, steroid therapy has been shown to be ineffective or even harmful. Can an infection get worse while on antibiotics? […]
Why does everything seem so quiet after a snowfall?
Why does everything seem so quiet after a snowfall? But there’s science behind the silence as well. That’s because snow absorbs sound, so when a fresh blanket of snow covers the landscape it absorbs many of the sound waves, making it seem quieter outside, according to AccuWeather. Those spaces absorb sound waves, creating a quieting […]

Why are longer wavelengths absorbed first?
Why are longer wavelengths absorbed first? Light with longer wavelengths is absorbed more quickly than that with shorter wavelengths. Because of this, the higher energy light with short wavelengths, such as blue, is able to penetrate more deeply. What color is most visible underwater? (1) The colors of highest visibility are: for the fluorescent paints, […]

How do you calculate exponential population growth?
How do you calculate exponential population growth? From the given data, we can conclude the initial population value, x0, equals 10,000. Also, we have the growth rate of r = 5%. Therefore, the exponential growth formula we should use is: x(t) = 10,000 * (1 + 0.05)t = 10,000 * 1.05t . What is exponential […]
What are the similarities and differences between electric and magnetic forces?
What are the similarities and differences between electric and magnetic forces? Similarities between magnetic fields and electric fields: Electric fields are produced by two kinds of charges, positive and negative. Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges). Like poles repel; unlike […]
