In physics there are countless scenarios where solving a problem in a Cartesian coordinate system is way harder than solving it in a spherical coordinate system (this rotated in and out of screen so you have a 3D space).

Your post is the dumbest thing I've ever seen.

You have to expend energy to get to the top of the staircase, the energy used to get up there came from your food which came from the sun. When you hit the ground (air resistance not withstanding) your kinetic energy (a function of speed) will be equal to the potential energy you acquired by going to the top of the staircase, which is equal to the amount of energy you expended to get up there.

In real life, a little bit of the energy will be lost heating up air molecules as you collide with them but that's really neither here nor there for illustration purposes.

Are you on campus right now?

If so, you should definitely do this in person. Are you trying to go to graduate school?

I think there is a clear difference in what OP is saying. Certainly science suggests consciousness is a property of the brain but I can certainly see the room to wonder whether or not a brain that was given all of your memories, hell even constructed atom by atom, would be the same "you" as the you I'm replying to right now.

Maybe an outside observer would never know the difference but there isn't really a way to know if you are still the one experiencing consciousness.

I am a PhD student who works on external beam therapy for oncology. I'm also loosely involved in a project to lower the doses suffered during CT scans.

Uhm, I'm pretty sure the whole "add up all the numbers from 1...100" question is generally accompanied with a story about Gauss surprising his teacher by doing it elegantly, but someone might have realized the method before him.

At least they are what I think you mean by isomorphic, insofar as there exists a bijection between them.

Have you tried to establish a bijection between the two?

Protip: They're isomorphic.

No, which is why I chose medical physics over real physics.

You're clearly missing the point.

What do you mean you're "talking about logic"?

>Numbers are certainly real

As I told someone before on this board, I would challenge you to show me a six in nature. You can show me six apples, certainly. You can also show me a tree that we would both reasonably agree is tall; but in this latter case you haven't shown me "a tall."

No numbers "really exist," go ahead and show me a six in nature.

I always did this, I took my notes with the textbook, not lecture. Like you said, I can reread a passage as many times as I'd like but the professor is--ideally--only going to say something one time.

To be honest, one expects a higher level student to figure out the core of Calc 3 on their own as a great deal of multivariable integration/differentiation is precisely what one would expect.

So I guess Calc 2 would probably be "harder" as you're being introduced to concepts you can't really reason out from Calc 1 knowledge.

> My landlord is a high school teacher and he CAN'T fail students. As in he will lose his job if he fails more than a few students a year.

I went to an utter shithole of a high school, you'd have thought you were in Compton if you walked the halls with no other knowledge. They actually instituted a policy where the lowest grade you could get on something was a 60.

When I say "lowest grade" I mean that if the teacher assigned homework, and you didn't do it, you got a 60. If you didn't show up for a test, you got a 60 on it unless you wanted to retake it. If you enrolled in a class, straight up didn't attend one lesson or turn in one assignment and didn't sit for a single exam... you got a 60.

It's just a shame that that is how lost we are in this country, that a school considers faking success ("success" for my high school meaning the graduation rate was above 50%, we had a whopping 52% my year, for the first time in over a decade) easier than teaching kids how to write a sentence or do some fucking introductory geometry.

Honestly the Grateful Dead skull had me wondering what hallucinogen it was as well.

A lot of the conclusions we seem to be comfortable drawing about organisms living a hundred million years ago are nowhere near up to the level of the scientific method.
