The Photoelectric Effect
The effect describes the emission of electrons from a surface, typically metal, in reaction to incident light. What happens is that the incident light is absorbed by the electrons (called photoelectric because their excess energy derives from light) within the metal, giving them the needed energy to be released.
Light has wave-particle duality, a prevalent concept in the quantum world that explicates particles possess both wave-like and particle-like properties. Einstein proposed that light consists of photons that interacted with electrons not like waves but like particles. For any frequency of the incident radiation, E=hf (Planck’s constant*frequency) measures a photon’s energy. So, the higher the intensity of the incident light, the more incident photons and the more emitted electrons, each of which would carry the same average energy, presuming that for every absorbed photon is a released electron. To increase energy of the photons and therefore the electrons, we look to the aforementioned equation - f and E are directly proportional, therefore all we’d need to do is increase the frequency of the incident light.
Einstein’s expansion on the photoelectric effect earned him the Nobel Prize and forever changed how physicists viewed light. In other words, this shit’s important.
Thought I would share a video I made about a year and a half ago when the Jesusita Fires engulfed Santa Barbara. Video and Photos included were shot by Me, Pandarsis :-)
No doubt we have all hit “speed bumps” in our lives. These bumps come in many forms ranging from physical manifestations to mental or even emotional hurtles that stop us in our tracks and cause us to take a pit stop on the race track that we are speeding down. No matter how grueling or grinding these situations can be on the cogs of our lives, we must always regain focus and determination to improve and move forward. The best way of achieving this, and turning a speed bump into a boost in speed is to create tangible entities of your motivation, and use physical reminders of what drives you.

It isn’t often that a video simultaneously inspires creativity through art AND salesmanship. The video obviously makes me want to buy an M3, but at the same time brings up so many cool photo and video ideas I don’t even know where to start!
An interesting angle on how Places may fail. good to read if you are curious about how this little competition will turn out!
My first Tech-post as Pandarsis, yet to me this seems a bit… well… fluffy.
Good news though, it involves the iPhone!
Facebook has just released its latest update to its’ iPhone App and the biggest addition is the newly released “Places” feature, which is basically a replica/rival to FourSquare. For those of you not “in-the-know” (read: lives in a cave, ignores technology, has better things to do in life)…
Ok not the most professional, but I couldn’t resist…
