Marianne Freiberger reports on a discussion she had with Bernard Carr on whether or not multiverse theories are science. He has a suggestion for how we should classify these theories.

The conquest of the Americas
This morning, I came across an essay by Howard Zinn, the famous historian and activist (now deceased), on the real historical Christopher Columbus. I suspect Zinn's portrayal of events was a bit one sided (I doubt the Native Americans were quite the lambs that he portrayed), but he probably overcompensated to some extent for the version we … Continue reading The conquest of the Americas
Mars One and done?
Mars One, a non-governmental plan to send colonists on way trips to Mars starting in 2025, has been in the news a lot over the last year. While I'd love to see us establish a human presence on Mars, the Mars One project has always struck me as a flawed plan, with far too many optimistic assumptions. It … Continue reading Mars One and done?
The myth of the eight-hour sleep
For much of my adult life, I've had trouble sleeping throughout the night, often waking up in the early morning hours, unable to go back to sleep.

Saying that mind uploading will never be possible is unwarranted
This question came up on Quora: 3 What percent chance is there that whole brain emulation or mind uploading to a neural prosthetic will be feasible by 2048? - Quora. After seeing a number of skeptical responses, many claiming that mind uploading was inherently impossible or even incoherent, I posted the following reply: I think mind … Continue reading Saying that mind uploading will never be possible is unwarranted
Chaos theory and doubts about determinism
I've mentioned a few times before that I'm not a convinced determinist, at least not of the strict or hard variety. I have three broad reasons for this. The first is that I'm not sure how meaningful it is to say something is deterministic in principle if it has no hope of ever being deterministic … Continue reading Chaos theory and doubts about determinism
