Reproducibility To reproduce an observation, you need to know all of the important circumstances of the observation. For example, consider the observation that the sun rises in the East and sets in the West every 24 hours Someone who repeats that observation in Murmansk, Russia, during midsummer will see the Sun circle the sky without ever completely setting at all. An important detail has been omitted: The observation must be made "in this part of the world in modern terms,...

1.2 Models of Reality Where does the Sun go? At a very young age, infants learn to go from simple observations to mental models of what they are observing. The simplest sort of model is called "object permanence" and just means that something can be hidden or out of sight and still exist. urement? In the case of the Sun rising and setting, this model suggests that it is always the same Sun, which means that the Sun must somehow...

[13] 7. The magnetic field through the conducting square loop at the right changes according to the relation B(t) - 2.5r-6.8t+5 T, where t is in seconds. Each side of the square is 321 cm long and the resistance is 56.8 u. Determine the current (magnitude and direction) in the loop at t- 5.6 seconds? (Hint: For the direction of the current you need. determine if the magnetic field is increasing or decreasing with time.) Answer: (a) 1.19 x 10...
