I spent some time looking at the validity of barefoot running. I've been running barefoot for a while and love, but I've met a lot of skeptics. This study added a lot of proof to what I thought was true and helped me find out some new things. The first runner is me, and the second is my brother, Tom.

Let's learn some particle physics! This presentation is based on the god particle, or Higgs boson, and how scientists at CERN are working at finding this very elusive elementary particle. Pause the video to read!
ELECTRIC LOW DOWN
Conductors: allows electricity to flow through it (Copper)
Insulators: do not (plastic/glass)
Electric current: flow of electrons (negatively charged)
For a circuit: a power supply (Battery) and something that needs the power (lamp) and something to carry the current (Copper wire)
Electrons flow out of the negative side of a battery and travel along the conducting material, they are attracted to the positive end of the battery.
Vampire energy: sends more than 87 billion pounds of heat-trapping carbon dioxide into the atmosphere each year.
Energy goes to the lights and things that stay on after the appliance has been turned “off”
Chargers/toasters/washing machines/etc. left in the wall also expend energy even if there’s no light visible
One of the most common ways to produce electricity is through the burning of fossil fuels (coal, oil, and natural gas). When fossil fuels are burned, they release carbon dioxide into the atmosphere, which leads to acid rain and global warming.
We refer to a lot of things as “energy"= fuels for cars/production/and electricity!
In the United States, the most common way to make electricity is by burning coal, which is also the dirtiest fossil fuel that releases the most carbon dioxide
Naturally occurring electricity! : Lightning and static
CONCLUSION: UNPLUG IT!!!!!!!!!!!!!
