The Matter of Everything by Suzie Sheehy review – 12 experiments that changed the world

The Observer 04 May 2022
But as she shows, particle physics has changed how we live dramatically over the last century ... She begins with Röntgen’s discovery, before moving on to early experiments showing that the atom was composed mostly of empty space, with a dense nucleus surrounded by electrons, and on to the creation of the first particle accelerators in the 1930s.

NASA Confirms Largest Comet to Date – Not Headed to Earth

The Facts 30 Apr 2022
The Hubble images suggested similar measurements but unveiled a darker and much bigger nucleus than ALMA's rendition. The obstacle here was separating the comet's nucleus from its massive "coma" or "tail," which is melting ice and dust particles departing from the nucleus as it gets closer to the sun.

The Standard Model is a long-standing theory that successfully describes particles of matter such as the electron and force carriers such as gluons ... The neutron, which normally resides in an atom’s nucleus, decays into an electron, a proton and another particle called an antineutrino when it’s removed from the nucleus.
