In beta desintegration, a down quark becomes an up quark by the weak force. We have to add one positive charge to make it work, and it comes from a virtual positron/electron pair. The positron changes the down quark to up quark and the electron scapes. But why does it scape because it's near positivly charged quarks? And why does that positron react with the down quark and not with the positron? (I'm not very good at this, i hope you understand, probably almost everything that i think is wrong but i want to know why)

This is not a correct description of what is going on. Beta decay is mediated by W bosons and also result in a neutrino.

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!

Thread 'Does a qubit break interference in the double slit experiment?'

According to recent podcast between Jacob Barandes and Sean Carroll, Barandes claims that putting a sensitive qubit near one of the slits of a double slit interference experiment is sufficient to break the interference pattern. Here are his words from the official transcript: Is that true? Caveats I see: The qubit is a quantum object, so if the particle was in a superposition of up and down, the qubit can be in a superposition too. Measuring the qubit in an orthogonal direction might...
