Let's say like in this article 100000 times or 1000000 the level allowed in drinking water for PFAS. Let's say the safe level of PFAS is around 2 ppt or 0.002 ng/L for drinking water. Let's multiply this with an additio

Definitely frame theory in linear algebra. It is part of linear algebra, so you already mentioned it. I wasn't taught this in university and found it later. At first I understood much of nothing and it looked really complicated and con

Real time with DFT is a bit sketchy. Just view it as a matrix vector multiplication. The vector is the sampled signal at discrete time steps of equal spacing, the matrix is the DFT of fixed size. You need to fill your vector before the mul

It will be a bit difficult, you may have to avoid the natural amphetamines and some of the stimulants. The German gingerbread contained them aswell, all store bought gingerbread had to change the classical recipe. There are lots of instant

I think chai is bread in India. I was in the outskirts of Varanasi over a decade ago, no ATM was working for me and I had no cent to my name. I had a nice prepaid cap driver, who didn't seem bothered by this and brought me to a place w

Their advantage is just dwindling quickly. Asking to pause the development of anything more powerful as the own product. The audacity of it.

Check out EXCEL induced genome renaming. Like the northern star, a refusal to waiver under any persuasion.

Expectation to a substance is the key to addiction. When you drink an alcohol free beer or wine you will feel a little exhilaration. This effect fastly fades when expectation and substance synchonise again. It is possible, that your expecta

I enjoy how you couldn't get if I had these problems, that somehow normalizes it all. Thank you. I really try to not be condescending about it and to be a smart person. I will try the "Glad I could help". Others made good po

Let me throw in: signal detection and estimation by Murat Barkat I stumbled across it, love it, very hands down and clear with focus on practical engineering problems.

Well it usually goes like this: Excelling the degree > passing it barely > not starting the program > switching > quitting > failing Generally quit before you fail, but if you quit it would have been better not to have persue

What helped me with my inferiority complex was realizing everyone else only appears to be competent and is blinded and overwhelmed by the simplest things. For me it is kind of normal to skim through a manual or a documentation to understand

Apparently inflation is measured with a consumer price index, which represents some predefined basket of consumer goods. One could define a coupon, that may be exchanged for said basket and it would be an inflation stable currency, right? T

Well meat profits most from subsedies since it is the last in the chain. I think it is not as simple, we would throw a lot more food away without our animals. Sure there is room to optimize and improvement. The city of Wien has an overprodu

If any of the planet saving meat substitute promises are true, such a fake meat patty would cost a tenth of the beef equivalent and it would dominate the market. I read somewhere you would need 25 kg of feed to produce 1 kg of beef, ergo on

Right... And resizing a jpg to lower resolution isn't actually taking the original jpg, but a "sample" free of copyright. When you also go so far to mirror the image, it is practically a new creation. Applying some filter and

Interesting hypothesis. The person interacting with it, has another train of thought and might find the answers more appealing or clever, then somebody else who is reading the conversation later on. Since it just extends your inputs and bro

Absolutely necessary. For smaller projects and test setups I repurpose old laptops as controllers. They just control some measurement devices and collect data. They all get a single sticker on the outside and a cool nickname. Without a fun

You say it yourself, it is trained on stack, which is advancing everyday with fresh information. While the transformer is trained once and stays the same, until there is a new version. If it is better and more polite than stack, that would

It is very much depending on the topic. What usually works well for me with technical stuff is just doing the thing. Write a little program, play with it, crash it and repeat. For supposedly superficial knowledge and mathematics etc. the go

We still need it, as the damaging UV light isn't fully blocked just mostly absorbed. Most of the UV-C light is blocked, which can cause serious damage. Then there is UV-B and UV-A. They all can cause sunburn and some of it will still r

From second hand I pesonally would prefer Intel. AMD are usually less expensive when purchased new, but offer less safety features in regards of overheating, overclocking and other abuse. Intel's are guarded casual consumer products an

They already try to sell it as a subscription. So you don't pay for the lightbulb itself, but for the service that there is light. It is kind of a ridiculous concept for private customers. There have been some Phillips light bulbs wi

Would you say that university and school aren't inherently delayed gratification? No matter the topic, you study for a while, then do your examination. This process has a delay, there is lots of learning and teaching on the way to end

The first German Wind farms had direct connections, without expensive inverter stages. So they are generators, but they are also indistinguishable from motors. There is sometimes wind, sometimes not and the windmills humm about. I still hav

You are able to access the safety of such a device from one or two cycles against standardized loads, freshly manufactured or reused. If safety or fires would be truly a concern, costly test would be mandatory every year for each battery po
