Quantumaniac is where it’s at - and by ‘it’ I mean awesome.
Over here I post a ton of physics / math / general interesting science related posts. I try to be as informative as possible, all while posting fascinating things that hopefully enlighten us both a little to the mysteries of our truly wondrous universe(s?). Plus, how would you know if the blog exists or not unless you observe it? Boom, just pulled the Schrödinger’s cat card. Now you have to check it out - trust me, it said so in an equation somewhere.

J.J. Thomson’s Plum Pudding Model of the Atom
It’s safe to say that most people know the general structure of an atom, or at least what it looks like! Albeit a tad incorrect, most people are aware of the ‘big-orb-orbited-by-smaller-orbs’ idea, the classic Rutherford Model. (below)

However, before Rutherford proposed this model, J.J. Thomson, the famed discoverer of electrons, had a model of his own - the 1897 Plum Pudding model. He proposed that there was a positively charged cloud (the ‘pudding’) and small electrons (‘plums’) scattered throughout the cloud to balance the charge. Although incorrect, the model was an interesting idea, and it was among the first proposed model’s of the atom that could have been true. Thomson correctly proposed that the nucleus was of neutral charge, with equal numbers of protons and electrons.

Through his famous 1910 gold-experiment, Rutherford proved that the plum pudding model was own, and then proposed his own model - which we still, for the most part, accept today.
