PHYSICS OF TIME
First in time
The Egyptians were the first culture to become interested in timekeeping, building giant obelisks in 3500BC to act as giant sundials.
In 8BC the Roman senate gave ruling emperor August Caesar his own month (August, if that wasn’t obvious…) and added an extra day to match his great uncle Julius Caesar’s month (yep, July!) on 31 days.
Throughout World War II citizens in the United States kept their clocks one hour ahead of standard time to allow for longer working hours during daylight.
The world’s smallest atomic clock, built by the National Institute for Standards and Technology, is the size of a grain of rice and accurate to one second in 3,000 years.
In May 2011 Samoa decided to move its clocks forward by one day to allow easier trade with Australia and New Zealand, after spending 119 years almost a day behind.
is the study of electric charges that can be collected and
held in one place. The effects of electrostatics are
observable over a vast scale, from huge displays of
lightning to the submicroscopic world of atoms and
molecules. Electric charge is not created or destroyed, it
is conserved. Charging is the separation, not creation, of
THIS WEEK (3/21 - 3/25):
This week we will begin to take a look at electrostatics. We will learn that there are two kinds of electric charge, positive and negative. Like charges repel and unlike attract. We will discuss how objects can be charged by the transfer of electrons. When studying insulators and conductors, we will see that charges added to one part of an insulator remain at that part, and charges added to a conductor quickly spread over the surface of the object.
NEXT WEEK (4/4 - 4/8):
This week we will continue to explore electrostatics, particularly how to charge an object. Objects can be charged two ways, by conduction (by touching a neutral object with a charged object) and by induction (a charged object is brought near a neutral object and the charges separate). We will use Coulomb's Law to determine the force between two charges, which depends on the charge itself and the distance between the charges. The SI unit for charge is the Coulomb (C). Grounding is used to remove excess charge by touching an object to Earth.
