Almost nothing bad will happen—with the current variants. Uncontrolled spread in a sub population will almost certainly lead to new variants emerging. Given the reduced effectiveness of current vaccines against certain variants, this is re

Yeah, but the standard deviation goes by sqrt(n) for many operations, and there is significant autocorrelation. Interval arithmetic will give you worst-case bounds, which will quickly get fantastically pessimistic. Numerical analysis was a

It's still useful in options with very long maturities. Then the law of large numbers becomes important, and the vol smile flattens out over decades. These aren't listed, but are occasionally traded over-the-counter or embedded in

All good points. All I would add is that it costs money to flatten the delta every day, or delta hedging your option. Each time the stock changes direction, you pay the bid-ask spread. The number of times this happens is proportional in som

It actually is pretty easy to predict the future, in a limited sense, a decade out: the cost of new technologies generally follows an exponentially declining “learning” curve. This has been extremely well studied in the case of the aircraft

I’ve actually been using dotnet 5 on Linux recently. It’s been really successful, and to your question; I put performance critical bits in a .so with which I can use pinvoke. Speaks to the power of C, really because there’s been amazingly,

This can be especially bad if one corner hides a catastrophe. Any automatic method is likely to have an exponential struggle to sample appropriately. At a certain point, you just need to apply your own understanding of the problem you are t

To be very specific: if you’re not comfortable with implied teenage suicide and incest, give the show a pass. Also, it’s very confusing at the end, for the reasons mentioned above.

This is about gravitomagnetism. It would be beautiful if someone who studies electromagnetism in a turbulent plasma explain dark matter away. But these efforts always flounder on the bullet cluster results. I’m not going to get excited unti

I wouldn’t be so sure. We have experience with fast chargers, and know how fast and what it costs for EV fast charging. But how would a H2 fueling station work? Customers would have to make an extremely tight coupling, and while the compres

For your first question: in the TX power market, power producing companies contribute to a fund which will cover for losses if any participant defaults. Even with that little detail, the rest of your comment seems spot-on. These power prod

EVs will have cheaper up-front costs within 3 years for a in-city car, and by 2030 for longer-range models, according to most honest research. They are already cheaper for TCO, unless you add the artificial constraint that it is only charge

Just look at the first image on the Wikipedia page, showing the extent of the blackout. This is far smaller than the footprint of the eastern interconnect. The control software at the time made some simplifying approximations which left the

I am in MISO, which roughly runs up the Mississippi River, and borders TX. They have some real-time data available publicly. https://www.misoenergy.org/markets-and-operations/real-time-...

This is incorrect. MISO, the system to the north and east of TX, has capacity. The DC ties cannot handle it. You can see this by checking the price signals on their page. Right now, the TX hub is about $1,000 but the MS hub is about $60. h

AC transmission absolutely does work over large distances. It’s just not a point-to-point system. Imagine four cities in a row, all connected with AC. City A generates extra power, which gets sucked up by city B, whose power goes to the nex

They absolutely do have these associated costs. Robust electricity networks? The US has spent trillions on transmission networks in the era dominated by coal. Dispatchable power plants? We’ve had both base-load and peaker plants for decades

I disagree with a lot of this, except the conclusion. The economy never came close to a “total shutdown.” In most places, the overwhelming majority of jobs were classified as essential—maybe 2/3rds—even while certain sectors did shut d

The only one of these links which focuses on Democrats is the first one. Assuming the highly-edited video fairly represents the speakers’ contexts, they are calling for street demonstrations. If the events on the 6th had remained in the str

Please provide a source for your claim that Democrats encouraged riots. To the best of my recollection, no one encouraged riots, except for extremist groups like the “boogaloo boys.” Certainly no mainstream political party encouraged violen

The US consumes about 4 PWh/year, so bitcoin isn't comparable with the nation as a whole. However, that is more power consumption than many individual states, so your overall point remains completely valid.

The second is analyzing the law, and finding a provision that conflicts with a provision of the constitution. It’s not very formal, but it’s more than opinion. It’s not quite that pure. If there are self-contradictions in the constitution,

Have you ever read a warrant application? I have read a few, and they love to use the phrase "information and belief" to persuade the judge. That's just a fancy way of saying "speculate," and judges don't seem
