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
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?

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
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
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

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
That is the second. The “first” was linus going on an unhinged rant and shirking blame on the LTT forums
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
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
