Science Entry Electric Circuits

An electric Circuit is a complete path that carries electric current from one place to another basic circuit needs:1) A source: battery, plug, lemon, etc.2) A resistor: light bulb, motor, fan, etc.3) Connecting wires, switches, etcA circuit connects in a path these things. The positive and negative energy in a battery never need to connect (until they reach the resistor) or else they connect a short circuit. The flow of charge in a circuit is measured in volts (a battery has 1.5 volts, a plug has 220 volts) and the amount of current is measured in amps (more then 0.2 amps are deadly). Ohm's law states the resistance of a circuit is equals to the voltage (volts) divided by the charge (amps). Electricity is connected to magnetism if you connect a wire with loops (called a solenoid) to a functioning circuit you will produce a magnetic field. This magnetic field needs electricity to function, but it has the advantage that it is controlled by your circuit, so you can decide the power on the magnetic field (that depends on the voltage/materials/resistance of the your circuit) and you can turn it on and off.
Extra Italian Entry The Odyssey

Odysseus is a mythical hero, wise, intelligent, strong and king of the little island of Itaca. When his son is born, Odysseus is requested to the king Agamemnon to fight the war of Troy.

Social Studies Synopsis The Enigma Machine

While World War two was going on the Allies who had America ship them resources of supply their troops. The Huge American merchant fleets had to cross the Atlantic ocean (that was packed of German U-boats) to get to great Britain. The Germans used the (electronic) Enigma Machine (invented by the German company Sipson in 1935) to encrypt and decrypt messages. A message that had to go from Germany to a U-both had to go though certain steps:1) The real message had to be changed to a code using a secret code book (which had to be renewed every 6 months).2) The code had to be changed through the enigma machine3) The new message had to be changed to Morse and then it could be transmitted.When the U-both received the message it had to go through each of these steps backwards.The Enigma Machine was and electronic device that had 40 rotors on its outside. The key to solve a message depended on:1) Which 3 of the 40 rotors was set into the machine2) The order of the rotors in the machine and their initial position.3) The setting of some plugs behind the machinePractically one message had more the 300,000,000 keys and only one was correct. To decipher these codes the British had stolen an enigma machine and code book, established many radio centers and invented the first computers that could reduce the number of possible combinations.

After the murder of Tybalt Romeo finds hospitality at Friar Lawrence's cell and Friar Lawrence cheers him up. He also gives him hope with the quote "here from Verona art you banished: Be patient, for the world is broad and wide." and he tells Romeo that he will do his best to make his punishment temporary.
