Contradictions

Life is full of contradictions.

I am attending a research retreat on mindfulness and contemplative practices at the beautiful Garrison Institute. I am learning a lot of interesting things, and meeting a lot of like-minded and excellent people – the kind of people with whom I could have deep conversation about the unreal nature of reality, unlike most people from other walks of life would politely and tactfully excuse themselves when I get a bit unreal.

Speed of Light

The speed of light being a constant sounds like a simple statement. But there is more to it, quite a bit more. Let’s look at what this constancy really means.

And another ray of light going from left to right also has a speed c. So far, so good. Now let’s say you are in a rocket ship, como se mostra na figura abaixo, moving from right to left.
