The history of human expansion

In the video below the folks of RealLifeLore give a short summary of the history of the territorial expansion of mankind.

Given our nature as an expansionist species it seems to be inevitable we will eventually settle the world’s oceans, Antarctica and, of course, Outer Space.

On a loosely related notice, Margaret Kohn and Kavita Reddy have written an article on the Stanford Encyclopedia of Philosophy on the historical attempts to justify colonialism. They also spend some time explaining the difference between colonialism and imperialism.

Choline – again

Earlier we discussed the importance of choline in raising the level of general intelligence among the public. Now a study conducted by researchers from Arizona State University, reported by ScienceDaily, has found:

that a lifelong dietary regimen of choline holds the potential to prevent Alzheimer’s disease (AD). (source: Science Daily)

Alzheimer’s disease is the most common form of dementia and puts a high cost on both individual, their friends and family as well society at large. If choline can play a role in a wider strategy to combat dementia, we have little reason not to do so.

Space habitats: the way of the future?

Matthew S. Williams has written a good and elaborate article about space habitats on Interesting Engineering:

Are Space Habitats the Way of the Future

Williams discusses the basics of orbital space settlement and the major benefits and the important problems associated with this concept.

Coriolis effect

As pointed out in a previous post centrifugation is the method proposed in space colonization literature to replace gravity in orbital space habitats. Though the centrifugal force is the most well-known effect of a rotating object (if not, consider your washing machine for a moment), its sister force, the Coriolis force is less known.
