  • Everyone should learn the basics of troubleshooting!

    When trying to resolve a problem it’s really important to keep as many variables under control as possible so that you can find the root cause and fix it.

    I see lots of people who try a bunch of things without isolating the issue first but can’t figure out what is wrong. Then because they messed with it so much it’s almost impossible to figure out.

    This is important for car maintenance, home maintenance, electronics, computers. Just about everything that can break or stop working right in your life.




  • It is undefined because the inverse of division is multiplication. If you multiply by zero, every answer is zero. If you try to invert that operation you can’t know which number was multiplied by zero to get zero because multiplying by zero doesn’t produce a unique answer for each operation.

    Additionally, if you take the limit of 1/x as x approaches zero from the positive side the result approaches positive infinity. If you take the limit from the negative side it approaches negative infinity.

    An interesting thing to think about is whether multiplication by zero really makes much sense in the concrete world. You can’t really have zero groups of something or some number of groups of zero. Zero groups of anything is still nothing. We can think of that abstractly once we have the abstract concept of numbers, but in the real world that idea is nonsense.





  • This is the hottest question in theory of mind right now thanks to David Chalmers. It’s called the Hard Problem of Consciousness and it’s about connecting the reductionist view of the brain’s function with the first-person experience of consciousness.

    I think that any explanation of consciousness completely from “the outside” will result in not being able to quantify the experience part of it. Any explanation completely from “the inside” will eventually run into the same issues as empiricism where it will be limited by subjectivity. I think that fundamentally we can’t rigorously combine these two views because they aren’t compatible. The starting points for each view carry different base assumptions.

    Both may be true from within their perspectives but combining them is basically just stating that a subjective experience “maps” to a physical function. There isn’t any explanatory usefulness of mapping. It doesn’t explain why the subjective experience is there just that it happens when these other physical things happen. I’m not sure we’ll find an answer that truly resolves the hard problem, but we’re still trying.


  • I’m a personal fan of Daniel Dennett’s multiple drafts theory of consciousness. The biggest problem of defining consciousness is that the deeper you look into where it comes from the definitions we commonly use to describe consciousness fall apart.

    It’s a collaborative effort between different parts of your brain and the environment. A lot of it we aren’t even aware of. At the same time we often generate explanations for our behavior after the fact so our experience of consciousness tends to be mostly a justification mechanism, not necessarily primarily a control mechanism.





  • Transmission losses prevent most of what you are suggesting. Across a continent, even with high voltage low loss power lines, you lose 35% to resistance. This doesn’t count the added loss from stepping down the voltage at various substations and transformers along the way. You can expect another 8-15% more reduction from that.

    You’re suggesting that the amount of excess power from one side of the country could be enough to power the other side (while still meeting the demands locally) with 40-55% losses. Come on.



  • Why would anyone waste money on the worse option?

    Why do people have diverse stock portfolios?

    Hedging and diversification is important. Unforseen consequences and unknown future conditions can screw up your long term plans for 100% renewables. The more diverse our energy portfolio is, the unknowns become easier to weather.

    That is the answer for why we build and research something that is more expensive and may divert resources away from better options. To argue that there is literally no place for energy development other than purely renewable is a difficult position to defend.

    Your sandwich analogy is lacking because we’re talking about far future consequences of our decision. Maybe you plan to eat the sandwich a week from today. Which do you buy? You don’t have enough information to determine which will be better in a week. Do you pick the chain store’s because it’s full of preservatives? Do you decide to buy both in case one of them gets moldy just to make sure you have anything to eat?

    The consequences of developing or not developing potential viable solutions to energy requirements can be far reaching. Completely dismissing alternative options is just not rational.
