  • Slide 4
  • UC Santa Cruz Tesla @ Pacific Collegiate SCIPP UC Santa Cruz Teach students, learn about nature (Research) Smallest objects (Particles): Quarks How do objects form and stay together? Big objects in the sky: Stars, Black holes, Supernovae
  • Slide 5
  • UC Santa Cruz Tesla @ Pacific Collegiate 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 & Harder to see From Biggest To Smallest...

  • Slide 10
  • UC Santa Cruz Tesla @ Pacific Collegiate SCIPP UC Santa Cruz COSMOS: UCSC Summer Program for H.S. students http://epc.ucsc.edu/cosmos
  • Slide 11
  • UC Santa Cruz Tesla @ Pacific Collegiate 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 strange (Ozone) The air smell strange (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 12
  • UC Santa Cruz Tesla @ Pacific Collegiate SCIPP UC Santa Cruz ZorroZorro Drawing lightning with a sword Lights without cords
  • Slide 13
  • UC Santa Cruz Tesla @ Pacific Collegiate 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 14
  • UC Santa Cruz Tesla @ Pacific Collegiate 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 15
  • UC Santa Cruz Tesla @ Pacific Collegiate SCIPP UC Santa Cruz Learn about Transformers Where have you seen this before? Power comes out at 14000 Volts Power goes in at 120 Volts Commercial Transformer, hooked up the wrong way Commercial Transformer, hooked up the wrong way
  • Slide 16
  • UC Santa Cruz Tesla @ Pacific Collegiate SCIPP UC Santa Cruz We hear a lot about conserving Power (turn off lamps, air conditioners, close refrigerator doors...) Electrical Power is just converted wind, water, thermal power It is brought to your neighborhood on high voltage lines We hear a lot about conserving Power (turn off lamps, air conditioners, close refrigerator doors...) Electrical Power is just converted wind, water, thermal power It is brought to your neighborhood on high voltage lines Transforming Power Power goes in at 14000 Volts Power comes out At 120 Volts and a transformer brings it down to 120V
  • Slide 17
  • UC Santa Cruz Tesla @ Pacific Collegiate SCIPP UC Santa Cruz Transformation of Power 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 18
  • UC Santa Cruz Tesla @ Pacific Collegiate 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
  • Slide 19
  • UC Santa Cruz Tesla @ Pacific Collegiate SCIPP UC Santa Cruz Meet the Fighting Knight Fighting Lightning Bolt to the Head
  • Slide 20
  • UC Santa Cruz Tesla @ Pacific Collegiate 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 22
  • UC Santa Cruz Tesla @ Pacific Collegiate SCIPP UC Santa Cruz The Faraday Cage Planes are close to the clouds and away from safe ground. Why arent they in grave danger from lightning? ++ + + + + +++ ++ + + +++ + + + Safest place during a lightning storm is in a plane or car because it is a Faraday Cage Answer: They form a Faraday Cage -- that is, they are surrounded by metal. Electricity flows around the outside of the metal, and anything inside is safe!
  • Slide 23
  • UC Santa Cruz Tesla @ Pacific Collegiate SCIPP UC Santa Cruz The Chicken Coop The Worlds Ugliest Faraday Cage -- and its full of holes! But can it keep the lightning out? Does the chicken trust the equations? equations?

  • Slide 28
  • UC Santa Cruz Tesla @ Pacific Collegiate SCIPP UC Santa Cruz Electrical current flows on the OUTSIDE of a metal! Is the Mystery Knight OK?Lets check! The armored suit is safe! n It's a Faraday Cage no electric field allowed inside. Is the Mystery Knight OK?Lets check! The armored suit is safe! n It's a Faraday Cage no electric field allowed inside. Invisible current Visible sparks Ground 1 Million Volts Visible sparks
