In the Time Lords’ Citadel

No, this is not a Dr. Who fanfiction, but I couldn’t resist the allure of what I like to think passes for a clever title for a post about a new change to international standard timekeeping.  That’s right: instead of worrying about minor controversies over things like religion, politics, or the Great Pumpkin, what should really be getting your blood pressure up is the CGPM’s vote to abolish the leap second.

Number Systems

This is one of those concepts that is both simple and mind-bending, so I will being doing my best to explain and explore it for you here.  As always, if you have any questions following this discussion, I’m more than happy to engage further in the comments.

Space Debris Economics

Why should a private company make a business out of space debris removal?  Alternatively, can space debris removal be made into a viable business model?  This is one of those complicated questions that I recently saw reduced to a gross oversimplification in a news article.  There were a lot of issues with the article, and I don’t want to dwell on it, but I think the biggest problem was its underlying, unstated assumption that the only viable business case for space debris removal as a commercial service was if the government was the customer, or regulated private space industry into becoming customers.  The underlying argument of the article, therefore, is that there is no viable business model based on space debris removal.
