A black hole is a region of spacetime where gravity is so strong that nothing, including light and other electromagnetic waves, has enough energy to escape it. Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of no escape is called the event horizon. A black hole has a great effect on the fate and circumstances of an object crossing it, but it has no locally detectable features according to general relativity. In many ways, a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes, making it essentially impossible to observe directly.

no I mean, here if you have mom issues it can happen regardless of if your left or right or whatever you want to accomplish in life, but it's going to be tinged that for some reason a woman who you were probably physically stronger than by the time you were 12 was able to have complete control of you mentally and without going over that line you basically just resorted to being locked behind that restraint for the rest of your life along with strong anxieties

>What good did prohibition do in the US?
Always the same excuse when it comes to banning alcohol. As if no other drug was banned in the world. As if the world, society, medicine, education, treatment of disorders, surveillance methods, etc. hadn't changed since 1920 (prehistory in terms of progress) in our modern countries (Europe + North America)... As if it were as easy to make your own alcohol in your own apartment and sell it on the black market in 2024 as it was in 1920. As if society hadn't become less tolerant and more informed about the ravages of alcohol (and even more so of adulterated alcohol).

Thanks. This is the sort of answer I’ve been looking for: The reason for ITER’s apparent delay is neither triple product being a bad measure, nor ITER being a terrible project, but is instead that the data on the graph is wrong, so the trendline is inaccurate representation of triple product gains over time.

Thanks again for that graph, paints a much better picture of ITER. Where’s it from? (not trying to pull a SOURCE??? on you)

If you happen to know, what makes a reactor’s triple product larger? Bigger reactor plasma volume as i suspect? Denser magnetic fields?

Also what’s caused rate of triple product gains to slow? Just don’t have strong enough magnets or building materials to cope with forces generated?
>>
>>16050026
If you look the website is annotated.

ITERs gains mostly come from a longer energy confinement time, which scales strongly with radius.

>Also what’s caused rate of triple product gains to slow?
There is no reason to expect that it should be exponential. A straight line on that plot. If we plot using a linear axis for the triple product instead of log, ITER would be a huge jump. Bigger than any previous jump. In that metric gains have accelerated. There is no objective way to measure the speed of progress.
>>
>>16050026
The reality of these experiments is the more energy that gets put into the plasma, the more vigorously and creatively nature finds ways to release it. More than that, fusion reactions themselves poison the process, demanding even more fuel and energy. Yes, stronger magnets need to be developed, but the fundamental compensation ends up simply being the size. You can always make a fusion chamber larger (at great expense) in order to increase the triple product. But to your point, the actual chamber that could achieve continuous net gain (not just for a split second) could very well be too large to ever construct.

>>16050409
Because the goal is to make the most extreme combinations of microwave ovens, particle accelerators, super conducting magnets, cooling systems, power delivery (and even more systems in the case of a power power plant). This all has to culminate around the fusion chamber which itself must maintain a high vacuum. For ITER there will never be more than 1 gram of fuel in the chamber. This all adds up to larger equipment, more infrastructure, thicker and thicker materials, which at some point will exceed plausibility.

What's some good /sci/ books to have?

Here's a book on how biotechnology could make it possible to abolish suffering entirely. There's a British woman named Jo Cameron with a rare genetic mutation that causes her to experience almost no physical or psychological pain with seemingly no side effects. Genetically engineering the population to have Jo Cameron's genetics would drastically reduce the amount of suffering that exists in the world.

Inflation is the result of printing money, by anyone, most significantly governments.
Printing money causes inflation because whoever printed the money goes and spends it. By purchasing assets, they increase the demand for those assets. Whenever demand rises without supply doing the same, the price of the asset rises.
Printing>Spending>Demand>Prices

Where does the value which allows printed money to pay for these assets come from? Everyone who holds their worth in the currency printed.
>>
>>16050125
False.

Look at the price of DNA sequencers, there was big demand and price dropped down.

>>
>>16049804
Dude what are you talking about? The original looks significantly better.

Symbology is only good if it is simple and exact. Students already like log, not because of understanding the log, but because it's one of the few transformations that we call out and name as a function, like sin and cos.

It makes reading, programming, etc. significantly cleaner. The only reason we don't use words more is because it would crowd things, but the Delta triangle replacing log, exp, and roots doesn't condense things at all. At best it helps students realize these are all related and if they're not low IQ they already will see that, at worse it actually DISADVANTAGEs them because where is the triangle symbol on the keyboard? How do I do this in excel?

Behind closed doors doctors have realized that nearly everyone who has had COVID even once has long term lung damage that is only treatable with a combination of steroids and a bronchodilator
Unfortunately due to the terrible PR currently surrounding the vaccine and the handing of COVID in general, the decision was made to not tell the public, and instead to only prescribe these the next time somebody gets COVID and then also goes to see a doctor about it.
I understand that they are trying to prevent panic, but I can't see this going the way they think it will
As soon as people start realizing that everyone they know is getting prescribed these medications, people will start asking questions and the backlash is going to be horrible
This is my attempt to get the information out there to anybody who will listen. If you don't believe me, go see a doctor and tell them you were sick with a cold a week ago and see how quickly you're prescribed these exact drugs.

I just went to my doctor for a swollen lymph node.
He asked if I had been "wheezing or having a hard time breathing lately"
I'm fairly young and healthy so it kinda threw me off, told me I had just gotten off some respiratory illness a couple days ago.
He offered me a fucking inhaler.
I do not have asthma.
Remembered this post and now I'm back here.
Wtf is going on? Why are they handing this stuff out like candy now? Apparently my neighbor got inhalent steroids too.
