Quantum mechanics

The Principal Quantum Number (\(n\)) The principal quantum number, \(n\), designates the principal electron shell. Because n describes the most probable distance of the electrons from the nucleus, the larger the number n is, the farther the electron is from the nucleus, the larger the size of the orbital, and the larger the atom is.n can be any positive …

Quantum mechanics works completely di erently, as can be seen by repeating the double-slit experiment for electrons. What one observes is that electrons still reach the detector in \lumps", but now P 12(x) 6= P 1(x) + P 2(x). Moreover, the observed probability distribution looks suspiciously like the interferenceHis record of successful theoretical research with undergraduate students was recognized in 2011 when he was named as a KITP-Anacapa scholar.
