Taylor series approximations work because the derivatives of the taylor series expansion and the function it is approximating are the same (and the values at the given point). Likewise, the derivative of e^{x is e}x because the taylor expansion of e^{x is 1 + x/1! + x}2/2! + x^{3/3!... which becomes 0 + 1 + x/1! + x}2/2! + x^{3/3!... when the derivative is taken. So the derivative of the taylor expansion of e}x is itself.

Purposefully licking things.

Chemists of old were a bit less safety conscious than we are today. Tasting the chemicals you just made was just part of the job back then.

I remember malort tasting like what I imagine grapefruit flavored floor cleaner would taste like. So yeah its much much much worse than jager

About half the things I said in an interview for a new job.

Sounds like they wouldnt have gotten the job in the "you are wasting my time" category anyway so nothing really lost there

It is shocking how many people there are in this thread that try to downplay this. And the sad thing is, most if not all of them arent getting paid a dime to shill.

Thats like saying congress is run by millennials because some of them are millennials. Most of them arent.

That paper isnt dealing with the same issue that I am talking about. Learning chinese isn't going to compromise someones' ability to understand physics. (Unless the problem is written in chinese I guess) But being weak on unit conversion will absolutely compromise their capability to learn a concept where the first problems they are meant to solve are written in a way that requires unit conversions.

In my experience tutoring thousands of students, one of the most common scenarios that I see is that a student struggled in an area like that, was taught in a way that relies on that weak skill to learn the new skill when that was not necessary and then struggled with the new skill as a result. Thats the sort of scenario that this thread is about. Mixing in concepts unnecessary to understanding into a problem thus overcomplicating it before the student has a solid grasp of the concept. That does make it harder for them to learn and its something bad teachers do.

This is not true. I literally have to fix conceptual issues that students have because people do this to them.

Neil armstrong etc. were all the silent generation. The boomers were in their 20s.

You work indoors for 9 hours a day, 5 days a week with little to no exercise and are inundated with multiple concurrent tasks that require prolonged concentration and a lack of errors and wonder why you feel exhausted?

I have tutored thousands of students. You are going to need to back what you say with relevant evidence.

If your goal is to teach new material, you teach that material specifically. You dont mix other things into it because 1) it makes it harder for them to learn that new material and 2) it makes it harder for you to figure out what they dont understand.

Probably shouldn't have committed all that fraud then.

Stop supporting Nintendo. Boycott them.

Nothing short of prolonged mass boycotting nintendo has any chance of changing their behavior and even then I bet nintendo would ride all the way into the ground blaming emulators and pirates for their decline.

To emphasize the privilege this guy has.
