Life on Venus: Proposed Biochemistry of Venusian Life

The possible detection of phosphines in the atmosphere of the planet Venus has sparked interest in possible biogenesis of the compound. In other words, there may be microscopic extraterrestrial organisms living up in the Venusian clouds. This would be an amazing discovery. But, it also raises the question about what sort of biochemistry such organisms (if they exist) utilize in their Venusian flavor of metabolism. Here I will make some speculations about this.

Lie Groups Simplified: the Symmetry Underlying the Laws of Physics

The laws of physics, to the amateur science enthusiast, can sometimes seem like a disparate bunch of equations without any real underlying connection. That doesn’t seem good enough, so you dig a little deeper, and soon discover that there is this thing called Lie Theory, with Lie Groups and Lie Algebras. You want to find out what all this is, and the only things you can find just give you another bunch of equations and leave it there as if those unexplained symbols are good enough for you to understand. Well, I’m at that point, and here I am going to talk about Lie Theory and its connection to physics in hopes that explaining things simply and intuitively will help me to better understand it – and if that helps any readers understand it better, that’s good, too.

Sex and Gender: The Science of Transgender Identity

gender identity and gendery equality

Possibly the most important part of the mental model humans construct is their mental model of themselves. This is what we call our identity. It takes all the beliefs we have about ourselves and attempts to put them together into an internally coherent whole. Some of our most cherished political, religious, racial, and gender thoughts about ourselves tells us who we are and how we ought to interact with the world.

Quantum Mechanics qua Being

Aristotle defined metaphysics as the study of Being qua Being – or, one might say, studying Being being Being. He says in book VII of his Metaphysics that Being is the individual instances of essence, which is the substance that defines what a thing is in-itself. Now, in our present time, we’ve narrowed down the primary substance further than our everyday sensible objects, down to subatomic particles. Can Aristotle’s philosophy be a useful lens to think about quantum mechanics?

Should Futurists Support War?

Since at least World War 1 the idea of war as being all about glory and heroism has seen massive disillusionment. Most people, I think, would agree that war is not a good thing, even if some think it a necessary thing. But technological arms races, both during war and in peacetime, generate a plethora of technological advances. That raises the question: should futurists and transhumanists welcome war in order to usher in greater and faster technological advances?

A Primer on Evolution pt 2: Evidence

evidence of evolution

In part two, I will give a brief overview of the evidence for the theory of evolution. This is not an exhaustive compendium of all the evidence in support of the theory of evolution. It is already a long post, so I keep all my descriptions brief. If you are interested in learning more, I provide plenty of links to websites and peer reviewed papers all throughout.

If you’re interested in how evolution relates to religion and whether it gives us any reason not to believe in God, check out this post. The current discussion will not touch on the subject, sticking strictly to the science.

A Primer on Evolution pt 3: Higher Concepts

evolutionary concepts

What follows are more conceptual aspects of evolution that build on the ideas discussed in the part 1. It’s not absolutely necessary, but I would recommend checking out part 2 first as well. In this conclusion to my three-part primer on evolution, I will discuss things like reproductive isolation, the different ways that evolution occurs, sexual selection, ecology, chaos theory, and evolutionary equilibrium. That evolution by natural selection has occurred and is occurring is not controversial in biology, which means most biologists are not actively searching for evidence that evolution by natural selection is a true phenomenon – the evidence that it is occurring is in. This post, therefore, introduces you to some of the areas of active research in evolutionary theory.
