Christians, read your Bibles

Now is a good time to think about new year's resolutions. It's an often maligned tradition, given how often they're broken or forgotten. But I do think that it's helpful to plan ahead on the time scale of about a year, and New Year's Day is as good a time as any to do that. […]

Christmas and time

I've previously discussed how long ago the universe began. Now, if the universe were purely physical, then this would be an one-dimensional question with a simple answer. But because of the depth and purpose expressed in the universe, multiple answers are possible, some more meaningful than others. To see what I mean, let's look at […]

Two year anniversary for the blog!

The first post in this blog was made on December 12, 2013 - just over two years ago. Since then, this site has accumulated over 200,000 page views. I am not dissatisfied with this result. At this point, one may be expected to say something like "I had no idea what this blog would become", […]

How to think about the future

This post is a consolidation of a whole series of posts into one post. It's fairly long. Click on the following entries in the table of contents below to jump directly there: The future is completely unpredictable No, really, the future is COMPLETELY unpredictable The future will be like the past, and therefore "predictable" The […]

How to think about the future (Conclusion)

Trying to predict the future is a good way to put your foot in your mouth. It's hard enough to just think about the future, let alone predict it. Even in this series of posts, all I have done is provide some rules of thumb: the future is impossible to predict. The future will be […]

How to think about the future (Part 4)

What I am about to say in this post is less certain than what I have said in the previous posts; it's a half-formed thought, which I only post because I think it may be more important than my other thoughts, especially regarding the future of human society. In short, this post will more nebulous compared […]

On becoming a good person

I don't care much about the recent terrorist attacks in Paris. I mean, it's hard to care, given some perspective. It happened half a world away. The death count at the moment stands at 136, according to Wikipedia. That's nothing. The world's mortality rate is about 0.8% per year - or about 100 persons per […]

How to think about the future (Part 3)

It's easy to predict the future. It'll be basically like the past. How could that be? Isn't everything changing all the time? Are we not living in an era of unprecedented growth and technological advancement? Isn't the world not only changing, but changing faster and faster? I mean, just look at the graph of the […]

How to think about the future (Part 2)

In the last post, I demonstrated that even if Marty McFly went back in time for just one second, just his gravitational influence would irrevocably change the future. I then claimed that this is actually overkill: that even small changes at interstellar distances will affect things on Earth. Let's see about that. (Most of this […]

How to think about the future (Part 1)

It turns out that the future is completely unpredictable. That may seem like a trivial statement. But most people have no idea just how true it is. A simple physics calculation may shed some light on this subject. In the film franchise "Back to the Future", the main characters Marty McFly and Doctor "Doc" Emmett […]
