Vaping vs Nicotine gum?

Anonymous Tue 12 Apr 16:01:03 2022 No.14388684 ViewReplyOriginalReport

Quoted By: >>14400830

How does nicotine gum compare to vaping? I've never smoked but started to vape for a nootropic/to help my ADHD. It helps a bit but I haven't done it much yet, just a few puffs every few hours.

I've considered switching to the gum because it's more subtle and can be done in public. But how is its effectiveness and safety compared to vaping? I've looked it up but most people compare it to smoking so that won't help me.

Someone with actual knowledge in this field please weigh in, I need to settle an argument in /co/

How hard would it actually be to calculate the exact positions of stars 2000 years ago?

Is climate change real, is it man-made, and is it going to be catastrophic?

Methoxetamine MXE

Anonymous Fri 15 Apr 21:41:31 2022 No.14398449 ViewReplyOriginalReport

Quoted By:

This compound is not harder to produce than Ketamine and yet nobody is producing it. All the supply remaining is from 2015 and earlier.
K sells for $60/g and MXE currently for $300+.
MXE is more potent (lower dosage required), lasts longer, has less physical side effects especially on the bladder.
Why isn’t it being synthesized? Anyone experienced in chemistry know how to? There is a huge market and demand for it.

I think I finally understand most of the harmonic oscillator. After having learned to derive the classical and quantum HO (first and second quantization, not that it's a meaningful difference) I decided to try to tackle the system from many angles and find as many connections as possible. Things like resonance etc are of course already in the standard literature and not worth mentioning, but I figured out a couple more interesting structures.
>how to reduce the classical equations of motion to a linear first order differential equation using noncanonical transformations
>the connection between ladder operators and said non-canonical coordinates
>an actually well-motivated derivation for the ladder operators as a consequence
>eigenfunctions of the quantum HO from fourier symmetry
>the classical analogue of imaginary time propagation to realize energy minimization/maximization
>complex phase space trajectories (can be interpreted as classically forbidden solutions)
What I know I'm missing is:
>general quantum solutions for V=x^2 for x>0, 0 otherwise
>relativistic oscillator
What else could there be to learn from in this system?

Why is dry air homogenous but a mixture of air and liquid air heterogeneous?
Isn't liquid air condensed from the air? How can a mixture of air and condensed air not be homogenous?
