  • Slide 4
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz What is a Physicist? A Person who asks Questions about Nature Today is your chance to be a Physicist: Ask Questions during the Show!
  • Slide 5
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Teach students, learn about nature (Research) Smallest bodies (Particles): Quarks How do bodies form and stay together Big bodies in the sky: Stars, Black holes, Supernovae
  • Slide 6
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Galaxy DNA Cell Atom Nucleus Electron microscope Accelerator The size of the object and its distance tells me what kind of instrument I need to see it. Larger & Farther away smaller Cartoon of the World
  • Slide 7
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Professors and Students (and Teachers !) conduct research in the SCIPP Laboratories http://scipp.ucsc.edu
  • Slide 8
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Summer 2001: Teachers help launch a big Balloon Mr. Kliewer Prof. Schalk Dr. Dann Mr. Manildi Mr. Briber
  • Slide 9
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Balloon Chase and Recovery Balloon flew 400 Miles at 130,000 ft across ???
  • Slide 10
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz n Normally you can't see, hear or smell electricity, but the Tesla Coil makes Bright sparks Bright sparks Loud crackling noise Loud crackling noise The air smell bad (Ozone The air smell bad (Ozone SAFETY FIRST! BRACE YOURSELF! 1 Million Volts! DANGER n Distance at least 20 ft. n Computers, Gameboys, CD players, telephones to the back of the room unplugged, switched off! n Hearing aids off, pacemakers out of room
  • Slide 11
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Meet the Fighting Knight Fighting Lightning Bolt to the Head Sparks from the feet
  • Slide 12
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Three things to understand: n Electrical Current n Lightning n The Faraday Cage
  • Slide 13
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Lightning Jacobs Ladder Corona Tesla Sparks are all related. Lightning Jacobs Ladder Corona Tesla Sparks are all related. Principle:Air is made of very small bodies called molecules. When they are broken apart, they become charged and can conduct a current like an electrical wire. If there is a large current, it heats up the air and makes light (like in your toaster!). Electricity in Air

  • Slide 15
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz The Faraday Cage Why aren't air planes in grave danger being so close to the clouds and away from safe ground? ++ + + + + +++ ++ + + +++ + + + Safest place during a lightning storm is in a plane or car because it is a Faraday Cage Answer: They form a Faraday Cage i.e., they are surrounded by metal; if you are surrounded by metal you are safe the electricity flows around the outside
  • Slide 16
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz ZorroZorro Drawing sparks with a sword
  • Slide 17
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Sparks to grounded sword What is happening with Zorro? Wire to safe ground What about those lights without cords? Electricity Moves Through the Air (you knew that, because you use a radio and TV
  • Slide 18
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Thomas DC Edison Thomas DC EdisonBatteries Nicola AC Tesla Generators vs. n Tesla Revival n 271 web sites are dedicated to Nicola Tesla n Join the Tesla Coil Web Ring http://nav.webring.yahoo.com/hub?ring=teslaring&list
  • Slide 19
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz n Nicola Tesla as a Daredevil waiting for a hair cut? n Double Exposure makes it safe!
  • Slide 20
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Voltage starts at 120 ends up at 1 million! Transformer 14,000 volt Outlet 120 volt Resonance circuit 1 million volt Ask us about details! How does the Tesla Coil work?
  • Slide 21
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Learn about Transformers Where have you seen this before? Power out @14kV Power in @120V
  • Slide 22
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz We heard a lot about conserving Power (turn off lamps, Air conditioners, .) Power is brought to your neighborhood on high voltage lines on high voltage lines and a transformer brings it down to 120V We heard a lot about conserving Power (turn off lamps, Air conditioners, .) Power is brought to your neighborhood on high voltage lines on high voltage lines and a transformer brings it down to 120V Physics Principle: Transformer Power in @14kV Power in @120V
  • Slide 23
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Transformation of Energy GLAST SLAC n Power is used everywhere Visit the Stanford Linear Accelerator Center (SLAC): Electricity -> New particles Quarks Power is tranformed in Space Power is tranformed in Space Black holes explode : Black holes explode : Material -> Light, x-rays, jets SCIPP works on GLAST Mission: discover the most powerful power plants in the universe discover the most powerful power plants in the universe
  • Slide 24
  • UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Learn about Resonance Thats how a swing works: A kick at the right moment builds up and gets you sky-high! Thats how a swing works: A kick at the right moment builds up and gets you sky-high! In the Tesla swing, the kick is supplied by the AC electrical current moving back and forth In the Tesla swing, the kick is supplied by the AC electrical current moving back and forth
