  • The other day I ordered a burger and they put tomatoes on it even though I asked them not to. I was about to complain, but decided to take a bite anyway and…huh. The tomato had no flavour whatsoever. I used to not like the taste of tomatoes but how could I object to this?

    So what does this mean? Are my taste buds not functioning like they used to? But I spent lunch looking it up and apparently, there is a fair consensus that tomatoes, along with a host of other fruits and vegetables, really are blander today than when I was a kid. For something I never liked, this kind of works out but…






  • Totally agree. Some people seem to think it shows moral fortitude to stick to your guns and never admit fault, but these are really the weak-willed people in society.

    Another lesson of adulthood it has taken me an embarrassingly long time to learn is that when you are enjoying something and see someone—particularly a younger person—looking interested, bring them in on it. If it’s something you bought for yourself, let them have a go. This may entail a small amount of sacrifice if you let them borrow it for a time, but the joy it brings will make it worth it, and the world needs more of that today. I think about people who have done this for me in the past, and I have mad respect for all of them.



  • Take it easy for about half an hour or so after eating and then do some kind of physical activity. I learned that this has the best effect for lowering blood sugar in battling type 2 diabetes, but I think it’s generally good advice for anyone? It doesn’t have to be a heavy workout or anything. Even just getting up on your feet and walking around a bit makes a difference.


  • But the mining, milling, and production of nuclear fuel, as well as the construction and decommissioning of nuclear plants, emit greenhouse gases at levels ranging from 10 to 130 grams of carbon dioxide per kilowatt hour of power — lower than fossil fuels but higher than wind and hydroelectricity (and roughly on par with solar).

    That’s interesting. The article they link gives a bit more detail:

    These energy intensities translate into greenhouse gas intensities for LWR and HWR of between 10 and 130 g CO2-e/kWhel, with an average of 65 g CO2-e/kWhel.

    While these greenhouse gases are expectedly lower than those of fossil technologies (typically 600–1200 g CO2-e/kWhel), they are higher than reported figures for wind turbines and hydroelectricity (around 15–25 g CO2-e/kWhel) and in the order of, or slightly lower than, solar photovoltaic or solar thermal power (around 90 g CO2-e/kWhel).

    The wide range for nuclear apparently comes from difficulties in estimating the carbon footprint of mining/processing the uranium, but that nuclear is sort of in the middle of the pack in carbon footprint relative to renewables in spite of the fueling costs is good to know.

    I suppose these sort of numbers may change dramatically in years to come. Take solar. A lot of focus seems to be on the efficiency of panels, which would almost certainly lower the carbon cost per unit of energy as it improves, but a breakthrough in panel longevity would also do that in an amortized emissions sort of way.


  • I guess the central premise of capitalism is that while every society has its haves and have nots, capitalism is supposed to encourage the haves to invest in the economy rather than hoarding their wealth. In return, they stand to get even wealthier, but a stronger economy ought to generate more employment and generally improve the lives of commoners as well.

    Unfortunately, in a never-ending quest to make wealth-generation more efficient and streamlined, employment is being eliminated through automation, outsourcing, etc. and the system is eating itself out from the inside. I doubt it can persist much longer, but what will replace it remains unclear. I pray that it will be something sensible that ensures everyone has their basic needs met and can still find rewarding pursuits in life. But there are so many ways it could go very wrong, and that includes staying on the current course.






  • It’s been a long time since I got my astronomy degree, but your version is what I recall also. Whatever small rotational perturbation in the initial gas becomes more pronounced as it coalesces in on itself and defines the plane of the star system. Planets form within this plane after it is defined, and they all travel in the same direction around the star.

    Regarding galaxies, the most common spiral ones like our own Milky Way follow the same principle at a larger scale. But there are also elliptical galaxies, not to mention irregular ones. In an elliptical galaxy, there is a more random movement of stars in a cloud around its core. So they look more 3D I guess, to go back to what the OP was asking about. I seem to recall the most accepted explanation for how these form is from the aftermath of a collision between 2 spirals? So presumably, when our galaxy collides with Andromeda in several billion years time, the resulting combined galaxy may emerge as an elliptical?
