Well, if they just inherit their dead dad’s debt, would that be a “good life?” Assuming a financial situation is why this occurred. If both parents die is the debt expunged or passed to next of kin? If the debt is passed, they would be forced to declare bankruptcy early in their life (destroying their credit), which destroys a lot of options like college, car ownership, etc.
By no means am I saying this is the better option, just seems like both were quite shitty outcomes to me
Googling a rough average returned 0.346 kwh/mile for electric cars between 2000 and 2022 (wide range, im aware). Traveling at 50MPH, you go 50 miles in 1 hour (assume you’re already going 50, and stay at that speed). So you’d use [0.346KWh/mile] *[50 miles/hour] = [17.3 KW] per hour @ 50 MPH
I torrented and seeded many torrents (its still seeding right now) and it can do at least 2 (havent tried more) jellyfin streams at once as long as I disable server side transcoding to reserve resources. I had the full arr suite of apps running along with ombi (gonna move to jellyseer, but imo ombi used too much ram on my 4GB laptop to be something I kept running). Is it perfect? No, it has quirks that will come up now and again but can I really complain when getting now 16 years of use out of a laptop I never thought I’d touch again once I built my desktop?
Edit: oh be aware, if you’re using old hardware, DO NOT use the newest versions of things like Linux mint, it possibly won’t have drivers that works for really old hardware (like wifi card, Lan card, etc.) and it won’t be easily apparent sometimes. I solved this with a friend who had the same laptop as me but couldn’t get internet once installing mint. It turns out he used a newer version of mint that did not have a way to support his wifi card and installing and older version solved it
I run some of my services (until very recently including jellyfin) on my HP pavilion G6 from 2007. It still runs my wireguard, backup pihole, heimdall, etc. I run it on Linux mint (it was familiar) and cant do most things on screen (lags hard) but I can ssh or VNC in just fine
Yes, in a sense. It technically isn’t vibrating them, but rapidly spinning them due to the constantly changing magnetic field (produced by the magnetron).
Since water has a dipole moment (one side of the molecule experiences a slight positive charge, while one side experiences a slight negative charge) it will react to changes in an electric field just like a magnet would
Edit: I’d also like to add this is not specific to water. Some fats and other food material also undergoes that rotation, and the same concept (with different frequencies and wavelengths) is used in industrial processes all the time to quickly, and efficiently heat materials
As a process engineer in a union steel mill, can confirm
Completely fair point, that I do not think I have the knowledge to speak on. On the Trigonometry Wikipedia page, he pops up a few times, and many trig identities are known as pythagorean identities. Perhaps its not fully trig, but was used as a basis to help discover trig? Without having the understanding pythagorus gave mathematicians regarding triangles, I would think it would be pretty hard to begin developing deeper math regarding said triangles
There will be those that do and dont get the “nitty gritty” of the theory side of the math. Those people sometimes become math majors. Normal people (joking, dont be mad math majors), need more than simply the theory side of the math and actually need to see/perform the application side of things. I never once “understood” the lesson in math class when we go over the equations with variables only. I only truly began to learn the material and be able to use it once we got to the example problems. We would do multiple in class and then I would understand how to literally go through the problem and perform the math that was expected of me on the homework, and subsequently the test. There is tons of stuff i know how to use in math, but by no means understand WHY it came to be, or HOW its works for the realm of mathematics. I wanna know how this math can help me solve real life problems, problems I will face in industry, or even just a cool way to apply math in the real world. Not how it will be used in research to find new types of math we wont be able to apply for 70 years.
It was pretty funny being in calculus in college. I was in a class with mostly engineers who were also taking the exact same weed out courses, and nearly every day after the professor would finish showing us the theory side of the lesson, hands would shoot up and the question of, “What application does this have in real life or engineering? Like, how will I actually use this?” always got asked. So not “loving” the theory is by no means uncommon (we all wished for an application focused version of the class to exist, for people like stem students who are not into the math theory lol), but I still see the value in having it presented so that you can have a more foundational understanding instead simply going through the motions
The reason they drill it in to the extent that they do is so that you have a foundational understanding of the underlying math on which to build new knowledge. If you show up in calc 1 in college without remembering even the basic concepts you were previously taught in things like trig…that can really bite you in the ass. My teacher LOVED pulling out classic substitutions for Secant, Cosecant, and cotangent (No, i didnt outright remember them from Trig, but I had seen them, and that made refreshing much easier). Also these concepts then form the basis of many other fields such as physics (electricity/magnetism, kinetic motion, optics, etc.), chemistry (quantum, MO theory, and things relating to the physics side of why chemistry occurs), and many of the graphing concepts used in engineering/stem only make sense if you have the foundational understanding of what integration/derivation are. Those stem from understanding how to graph complex functions by hand (like we did in trig) so that when you are doing it later with assistance, you still GRASP what is going on.
Yes its not perfect, and yes for people who never need that later in life it can suck. However, I would make the argument it is better to have more of your population educated to a higher standard than what is needed in daily life, than to only give that to those who are aware enough at a young age to actively seek said education
A^2 + B^2 = C^2 is known as the Pythagorean theorem. This theorem explains the proportionality of the 3 sides of a right triangle (a triangle with 1 corner angle = 90 degrees). If you know the length of 2 sides (in his example, the wall beams) you can find out the length of the third (in his example, this would be the supporting strut spanning the beams that meet at a 90 degree angle). If their example is explaining a beam that spans the room from 1 corner to the other, you still use this formula as a rectangle is 2 right triangles that meet along their hypotenuse (the longest leg of a right triangle, or the length you are solving for in this problem). The 2 known sides are the length/width of the room, and you solve for the 3rd side, your diagonal beam
You would use materials that perform completely fine at those temps. This could be anything from high nickel alloy steel, to Inconel, to an HEA (high entropy alloy). You can even do high heat resistant metals with ceramic coatings on the inside for protection if creating a passivation layer is too difficult for the application or the exposure environment does not allow for one to form.
There is an entire subsection of engineering studies focused on purely coaxing specific properties out of a material or developing materials to custom suit extreme applications, known as material science. They generally work very closely with chemical engineers (my background) and metallurgists in order to manufacture the designed product in either batch form, or in continuous fashion.
I work in a steel mill and we have Inconel furnace rolls that hang out in 1600 F heat 24/7 and are rated (iirc) to ~2300F max operation temp. For reference medium carbon steel melts between 2600 and 2800F, and loses a lot of its mechanical strength well before 2300F (I am trying to find a stress strain curve for carbon steel over multiple temperatures for reference. I will update if I find one)
Edit: Okay so I found one that does show what I am trying to convey. As you can see, the higher the temperature of the sample material, the lower the yield strength. Example: the 100C sample was strained to >25% before failure, while the 700C sample began to plastically deform (fail) before 10% strain. Take note of the second link, all the test temperatures are MUCH higher than any of the carbon steel samples

Where are you getting the 45% number? I am seeing petrochemicals (plastics, resins, and petroleum based feedstocks) @12.12% of total oil demand in 2022. I see that road (all forms of shipping and transport on roads/care with petroleum products like tar/asphalt) is 49.24% of demand.
Diving deeper into the transportation sector, light trucks + other trucks make up 57% of the transportation sector’s petroleum usage. Following with cars/motorcycles @21%.
I agree with the sentiment you raise, that industry accounts for a very large portion of crude oil consumption, and that isn’t going anywhere anytime soon. I just am unsure where you saw your data or if its perhaps looking at a different region specifically?

You can learn to create logic circuits in order to aid automation
Yes, I should be able to play music, AND charge the phone without a 9 wire adapter like those universal charger plugs from 10 years ago. Wild concept. I wonder when phone tech will be able to support such a thing
The issue in my eyes, and my number one complaint with this massive E.V. push (for many years now) is the insane environmental impact of lithium mining and the very short termed planning of just going hard on batteries (without spending more time and money on better battery tech [Toyota actually has that new solid state battery I’m very hopeful for, and we’ve been working on polymer batteries for decades]) we will waste a very precious earth material we WILL NEED in the future, and you never ever hear any of the politicians or CEOs talk about how dirty lithium mining and processing is because almost all of it happens outside the countries leading this push (thus, not their problem).
Not saying we shouldn’t be moving away from ICE, it’s that I feel our current approach is incredibly short sighted, and will have far reaching impacts into future generations and I feel as though we may even cause more damage than help in our current approach
I watch totally fine on my phone and pickup at home. It should sync to your log in account in my experience
Having been involved in plant shutting talks in the steel industry. You’d be shocked what companies are willing to do
Just came to say that companies will do exactly that if the law allows.
Entry level job:
Pay: $1-500,000
and pay you the lowest number you’ll say yes to
FYI, Biden did end up getting them their sick days. He never stopped pressuring the companies. There was just very little reporting on it so I don’t think anyone found out. I thought the same until someone corrected me and linked what I’m putting below
I just run a wireguard container on my raspberry pi 3b and use that to VPN onto my local network. Was super simple to set up
