The misconception is that electrons carry potential energy around a complete conducting loop, transferring their energy to the load. This video was sponsored by Caséta by Lutron.

Orbitals! Oh no. They're so weird. Don't worry, nobody understands these in first-year chemistry. You just pretend to, and then in second-year you learn them a little better, the following year a little better, and once you have a PhD you will know what they are. But let Professor Dave give you a head start!

"If you can explain this using common sense and logic, do let me know, because there is a Nobel Prize for you.." Professor Jim Al-Khalili explains the experiment that reveals the "central mystery of quantum mechanics" - the double slit experiment. Watch the full lecture here: http://www.youtube.com/watch?v=wwgQVZju1ZM For more info on all things quantum, you can buy Jim's book "Quantum: A Guide For The Perplexed" now - https://geni.us/32pvu Sometimes called the "two-slit" or "Young's" experiment, it demonstrates that matter and energy can display the characteristics of both waves and particles, establishing the principle known as wave-particle duality. Furthermore, it questions the role of the observer in the outcome of events and demonstrates the fundamental limitation of an observer to predict experimental results. For this reason, Richard Feynman called it "a phenomenon which is impossible ... to explain in any classical way, and which has in it the heart of quantum mechanics. In reality, it contains the only mystery [of quantum mechanics]," (see more at http://en.wikipedia.org/wiki/Double-slit_experiment).

Large Hadron Collider & The Higgs boson (GOD PARTICLES) explained by Physicist Brian Cox In this mind-bending video, Prof. Brian Cox explains how The Higgs Particles and The Higgs Boson were discovered by the Large Hadron Collider (LHC) in Geneva, Switzerland. The Higgs, the Particle of God, was first proposed in 1964 by Peter Higgs, and later in 2012, scientists confirmed its existence through one of the most complex scientific experiments in the history of humanity. The Large Hadron Collider (LHC) has enabled scientists to confirm its existence through the ATLAS and CMS experiments. With stunning visuals and expert insights, this video is a must-watch for anyone interested in the mysteries of the universe.
