The universe is made up of protons, neutrons, electrons and morons!

Just check out the flat earthers!

Are you serious or is this a canard?

Are you serious or is this a canard?

If you don't mind I'll duck giving you a proper answer.

On a different topic, I just noticed a thread in the forum titled Looking for Good Books on Photosynthesis and I thought, that’s certainly something that worth shedding some light on.

What are you all arguing about? The mammal in the water in post #1,089?

 

[Ibix]

You're all quackers.

Thanks for the link! When it comes to that topic, I'm a little green.

This thread has gone to the birds.

 

[Borek]

Technically it should go to the Electrical Engineering forum.

They turn out to be an orchestra. If you hadn't guessed.

If you consider buying a decent telescope, the only black hole you will find is the new one in your wallet.

I love it when human behavior can be expressed mathematically:

 

[nuuskur]

..so that he will be increasing the dosage? (if we forget about the intended derivative joke)

 

[strangerep]

I love it when human behavior can be expressed mathematically [...]

Shouldn't there be an integral sign? I.e. $\int\!e^x$

but I’m afraid they won’t get a good reaction

On the internet you need a -a-lyst.

The Great Unification Theory that unifies physics with electric engineering:
$$i=j$$

 

[Demystifier]

Application of the Great Unification Theory above to quantum mechanics. The probability current in quantum mechanics for a particle moving in one dimension is
$$j=\frac{\hbar}{2mi} \left( \psi^*\frac{\partial\psi}{\partial x}-\psi\frac{\partial\psi^*}{\partial x} \right)$$
Using the unification formula above, the current can be written in the electric engineering form
$$i=\frac{\hbar}{2mj} \left( \psi^*\frac{\partial\psi}{\partial x}-\psi\frac{\partial\psi^*}{\partial x} \right)$$

 

[mfb]

Write it as $$i=\frac{\hbar}{2mi} \left( \psi^*\frac{\partial\psi}{\partial x}-\psi\frac{\partial\psi^*}{\partial x} \right)$$ and simplify: $$-1=\frac{\hbar}{2m} \left( \psi^*\frac{\partial\psi}{\partial x}-\psi\frac{\partial\psi^*}{\partial x} \right)$$

 

[Demystifier]

$$-1=\frac{\hbar}{2m} \left( \psi^*\frac{\partial\psi}{\partial x}-\psi\frac{\partial\psi^*}{\partial x} \right)$$

The left-hand side is real and the right-hand side is imaginary, which is only possible if both sides are zero. Hence the wave function is real (which is compatible with the PBR theorem) and $-1=0$ (which makes sense because one cannot have less than zero particles).
