Comment Re:Ukraine is a terrible example (Score 1) 32

The comment at the top of this thread created confusion by using the words "telegraph" and "announce" as though they were synonymous: "Putin telegraphed to everyone weeks in advance in no uncertain terms he was going to invade Ukraine. Perhaps they should use an example of predicting an event that wasn't publicly announced beforehand.

Those numbers are suspect given that the govt gives out free food to everyone below poverty line. Cite a source.

According to Wikipedia,

Despite India's 50% increase in GDP since 2013,[1] more than one third of the world's malnourished children live in India. Among these, half of the children under three years old are underweight. ... The World Bank estimates that India is one of the highest-ranking countries in the world for the number of children with malnutrition. The prevalence of underweight children in India is among the highest in the world and is nearly double that of Sub Saharan Africa with dire consequences for mobility, mortality, productivity, and economic growth. ... 25% of all hungry people worldwide live in India. Since 1990 there have been some improvements for children but the proportion of hungry in the population has increased. In India 44% of children under the age of 5 are underweight. 72% of infants and 52% of married women have anemia.

You are missing the big picture, If I spent 40k USD to mine a XBT, I'm not selling it for less.

This is the sunk-cost fallacy.

If the market price for XBT is persistently a lot less than 40K, and you need money to cover the cost of living, then it doesn't matter how much it cost you to mine them in the past. The $40K cost of mining is already spent, and you can't get it back. You will sell or spend the XBTs at current market prices and eat the loss.

Two comments:

1) Your preferred candidate model is at odds with the _data_. Observational data is what you have to test a model against, and your preferred model fails spectacularly: it can't explain the baryon acoustic oscillation spectrum, or the large scale intergalactic structure, or the polarization spectrum of the microwave background, or the accelerating cosmic expansion rate. That's _why_ the current concordance model became accepted as most probable: it explains the data ... even data that were not collected at the time it was proposed! You might try reading about the successes and challenges of the Lambda-CDM: model https://en.wikipedia.org/wiki/... Whether the dark matter and energy eventually have a particle solution or not - and this hasn't been "proclaimed" by anyone, there are many competing hypotheses - the data very strongly require more types of physics than are currently described by the Standard Model of particle physics.

2) People like to rag on the aether model, and it's true that we no longer believe there is an aether, but that's because the _data_ don't require it. However, it was _not_ a crazy expectation. All wave phenomena known to the time required a physical medium to propagate in; light was a wave; ergo, the hypothesis of the aether as the medium to support light propagation. The aether fell out of favor because every attempt to measure its properties failed, and physics eventually relegated it to an interesting historical footnote.

As others have mentioned, muon tomography can be used to study geological structure and do non-desrructive searches of shipping containers, for dxample, for fissile materials. Muon spin resonance can be used to study the magnetic structure if materials. They also do chemistry, so they can be used to understand properties of chemical compounds.

You are completely right about the safety of nuclear power.

About China Syndrome, there is some important context. Right after the China Syndrome movie was released, nuclear power advocates quickly denounced it as utterly unrealistic, saying that it was impossible to have an accident like the one described in the movie: a loss of coolant accident that was caused by a malfunctioning gauge reporting excessive cooling water levels when the water levels were actually dangerously low because a valve got stuck, resulting in core melting.

Twelve days later, Three Mile Island had a loss of coolant accident caused by a malfunctioning gauge reporting excessive cooling water levels when the water levels were actually dangerously low because a valve got stuck, resulting in core melting.

No one was injured or killed by the Three Mile Island accident, but less than two weeks earlier, nuclear power experts had said that this kind of accident was impossible, and that killed public trust in nuclear reactors.

Bingo ... you got it. Many schools won't even accept donations of used equipment, because the cost of supporting and maintaining a heterogeneous fleet of hardware in the hands of schoolchildren and non-tech-expert teachers vastly outweighs the benefits. My childrens' district purchases hundreds of identical machines every few years to replace the previous fleet ... and then they donate the old fleet to non-profits or dispose of them, because no other schools want the "old" fleet due to support and maintenance costs of aging equipment.

The GeForce was the first GPU because nVidia coined the term to market that specific product. Graphics chips were not called a "GPU" before then.

"The term [GPU] was first used by Sony in 1994 with the launch of the PS1. That system had a 32-bit Sony GPU (designed by Toshiba)." — Jon Peddie, "Is it Time to Rename the GPU?".
