Can Aquaponics Fix Our Food Systems?


I’m working on my final project for my Master’s program.  All of my research has been on the failings and opportunities of global food systems.  This last effort is attempting to look at the opportunities of shifting a significant portion of soil-based agriculture to aquaponic systems which would be situated in urban settings.  (Aquaponics is the marriage of aquaculture, also known as fish farming, with hydroponics.)  Aquaponic systems bring numerous benefits by cycling nutrients in closed loop system that mimics a natural ecosystem.  Please take a look at the mind map below and share your thoughts in the comments.  Let me have it if you think I’ve made a leap too far, or I’ve left off an important idea.  I’d be happy to answer any questions you have as well as the goal is to put together a paper that has legs.  (What’s the point otherwise?)

Please do share a thought or a question, I’d greatly appreciate it! 🙂

Schrödinger’s Gun Cases: Unlocked and Loaded While Locked and Unloaded


Many Americans wish to have a firearm in the home for protection against intruders.   Unfortunately, having a firearm in the home brings a host of risks with it.   This paradox leaves people who wish to increase their safety, potentially decreasing it. For a firearm to be useful for self-defense, it typically needs to be loaded and readily accessible. For a firearm to be safe, it typically needs to be unloaded and locked up.

Due to this, Schrödinger Rifles has come up with a product that unwinds this quandary. They have developed a gun case that uses the latest discoveries in the field of quantum physics to hold the gun in two states. The gun is both locked and unloaded, and unlocked and loaded while in the case. When the case’s handle is pulled, it assesses the situation to determine whether there are any bad guys present, and then places the gun in the state that’s needed. Intruder in the home? Here’s your boomstick. Three year old nephew exploring your nightstand? They’ll never get into this vault!

But wait, there’s more!

Schrödinger Rifles has also developed a deluxe edition which holds the gun in three states, the third being “lost.” Police searching your home for the gun you used to rob a bank? Sorry, but it doesn’t exist when they open the case. How cool is that?!

The cases are now ready for pre-order and will be shipping soon. Click here to order now!

An economist’s mea culpa: I relied on Reinhart and Rogoff


High marks go out to economist Miles Kimball today. In the linked article above he holds himself publicly accountable for using Reinhart and Rogoff’s findings, and pledges to try to avoid such missteps going forward. Kimball’s humility is a breath of fresh air for a staid field, as Economists tend to stand by disproven theories, as if to do otherwise would remove all credibility. It should be just the opposite. Let’s hope that Kimball’s admission clears the air for others.
