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
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
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
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
Honestly (this is cliche as fuck) but keep at it. I think the contract positions I took helped me build a slightly stronger resume than just having worked highschool/college jobs, even though they were not directly in my intended field. I am a chemical engineer by education, and worked 2 contract jobs in “Product safety & Regulatory Compliance” (which I hated btw). I was afraid that it would essentially lock me into a field that I really had no interest in. This was not the case I discovered. I now have a job as a process engineer in a steel mill and absolutely love everything that I do. IIRC when they contacted me for the interview for this job, I straight up had forgotten I had applied because I had sent so many out. I believe I had applied multiple months prior before they ever even reached out. With how tight the labor market is currently (in the U.S.) I am seeing a lot of places have more legitimate “entry level” requirements. For example, my mill dropped its “prior industrial site experience” requirement
ENTRY LEVEL POSITION [Insert job title]
Requirements:
or
You apply and literally never get any form of anything back besides a confirmation email “thanks”. That was the absolute most annoying, demoralizing shit when I was searching for a job post school. I tumbled around 2 contract positions and finally have landed somewhere that I love, but fuck me was it hard on me mentally to keep farming out applications for basically a year, and hear back (I dont care if its a no, i just want some form of an answer!) less than 2% of the time
Severely depends on where you live. It’s very common in many areas of my state. Many farms have horses. Many people keep horses at other locations than their house, but still it needs a stable. Just because you don’t personally know people with horses in no capacity means it’s not something people still do
That is the second. The “first” was linus going on an unhinged rant and shirking blame on the LTT forums
I just want to make the distinction, that AI like this literally are black boxes. We (currently) have no ability to know why it chose the word it did for example. You train it, and under the hood you can’t actually read out the logic tree of why each word was chosen. That’s a major pitfall of AI development, its very hard to know how the AI arrived at a decision. You might know it’s right, or it’s wrong…but how did the AI decide this?
At a very technical level we understand HOW it makes decisions, we do not actively understand every decision it makes (it’s simply beyond our ability currently, from what I know)
Fair enough! Jerboa currently functions similarly to baconreader (which is what I used to browse reddit) so it has been a very smooth transition. I might try out some of the other offerings over the next few months, but I doubt I will be clamoring or a switch until either I am not getting something I want from Jerboa, or someone tells me about a feature I would specifically like on another app
Do you mean read posts or read mail? If you mean posts, I actually wouldn’t like that feature (for me). I like being able to find a post I found funny or pull up info for someone else, and seeing that it WAS read is helpful there
Here I am on jerboa wondering why it barely gets mentioned lol. It was all that was available in the first wave of migration and im used to it now. Sorta how I ended up on baconreader. Someone told me to try it, I had not used a 3rd party app before then (reddit didnt even have one at the time, the one they have now is steaming trash) and I got used to it and never looked for another. Until Jerboa isn’t doing what I need/want or begins to have functionality problems, I dont feel a need to change
Actually many bills are more of a fabric material now than an actual paper product. Many bills in Europe now are polymer based. Both of which add to the difficulty of counterfeiting
The mill I work in is already set up with shift work…they work 1st shift (week 1), 2nd shift (week 2), 3rd shift (week 3), and then go on long weekend 4 days off. My department runs 21 turns (we are the plant bottleneck by design), meaning 3 shifts of 8 hours, 7 days a week. Most people dont work 7 days straight unwillingly, but regardless of that fact, you need to keep running. Not running is losing money, losing money gets corporate to shut you down, getting shut down means you have no job and the company doesn’t care either way
There is a trade off when dealing with continuous operations. You run into the issue of, “Not running costs more money than running and paying people overtime.” Moving to a 4 day week just means you would likely get forced more into overtime so we can keep steel flowing, not that you get more free time.
Also from the salary side of things, I just spoke to 4 other process engineers and all of us immediately agreed that we cannot get the work done required of us + do the extras of being a floor process engineer in only 4 days. We could get our “requirements” done, but then all of the extra work that we perform would cease. It would actively hurt the company and its profitability, which in turn hurts our job stability. Its really not as cut and dry as people want to make it seem in all instances
Also to your other part about “it’s not that hard”
It actually is. We cannot get enough bodies in the mill to not work everyone at full time. We pay 18 year olds 6 figures to operate a mill and we still cannot get enough bodies to come anywhere close to working a 4 day week.
It straight up doesn’t work that simply when you’re running enormous 24/7 operations in critical industry. Thats like all the football fans on the couch yelling at the coach “JUST DO X”. Really easy to say “do X” but the application becomes extremely difficult. Yeah in an office, sure…in a refinery where you create base stock products that allow hundreds of other major plants to run to produce all the basic products you use every single day? Not gonna work that way
This isn’t some machinist shop that takes orders. it’s a multi billion dollar full rip steel mill/refinery/plant/etc. that loses LOTS of money when it’s not at full capacity. That has lasting knock on effects on other industries for example when base manufacturing can’t keep up
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
