2015.06.13 p.11 19484 Psychologists measure personality along five dimensions
2015.11.07 p.31 19952 Black holes have entropy, but general relativity says they are unstructured, and lack entropy

2017 Why the Universe Exists
01 p.5 21138 Neutrons are slightly heavier than protons, and decay into them by emitting an electron
01 p.7 21141 Neutrinos were proposed as the missing energy in neutron beta decay
01 p.7 21140 Spin is a built-in ration of angular momentum
01 p.14 21143 Quarks in threes can build hadrons with spin ½ or with spin 3/2
01 p.14 21142 Classifying hadrons revealed two symmetry patterns, produced by three basic elements
01 p.17 21144 Top, bottom, charm and strange quarks quickly decay into up and down
02 p.23 21145 The four fundamental forces (gravity, electromagnetism, weak and strong) are the effects of particles
02 p.24 21147 Quantum electrodynamics incorporates special relativity and quantum mechanics
02 p.24 21146 Electrons move fast, so are subject to special relativity
02 p.26 21148 The strong force is repulsive at short distances, strong at medium, and fades at long
02 p.26 21150 Three different colours of quark (as in the proton) can cancel out to give no colour
02 p.26 21149 Quarks have red, green or blue colour charge (akin to electric charge)
02 p.27 21152 The strong force binds quarks tight, and the nucleus more weakly
02 p.27 21151 Gluons, the particles carrying the strong force, interact because of their colour charge
02 p.28 21154 Three particles enable the weak force: W+ and W- are charged, and Z° is not
02 p.28 21153 The weak force explains beta decay, and the change of type by quarks and leptons
02 p.29 21156 The weak force particles are heavy, so the force has a short range
02 p.29 21155 Photons have zero rest mass, so virtual photons have infinite range
02 p.31 21157 Particles are spread out, with wave-like properties, and higher energy shortens the wavelength
02 p.31 21158 Fermions, with spin ½, are antisocial, and cannot share quantum states
02 p.39 21159 Supersymmetry has extra heavy bosons and heavy fermions
02 p.44 21160 The Higgs field means even low energy space is not empty
03 p.66 21161 In the standard model all the fundamental force fields merge at extremely high energies
03 p.69 21162 Only supersymmetry offers to incorporate gravity into the scheme
04 p.79 21163 The mass of protons and neutrinos is mostly binding energy, not the quarks
04 p.81 21164 Why do the charges of the very different proton and electron perfectly match up?
04 p.84 21165 Spin is akin to rotation, and is easily measured in a magnetic field
05 p.89 21166 Standard antineutrinos have opposite spin and opposite lepton number
05 p.99 21167 Gravity is unusual, in that it always attracts and never repels
05 p.101 21168 Gravitional mass turns out to be the same as inertial mass
06 p.109 21169 Only neutrinos spin anticlockwise
06 p.110 21170 The Standard Model cannot explain dark energy, survival of matter, gravity, or force strength
07 p.129 21171 The symmetry of unified electromagnetic and weak forces was broken by the Higgs field
07 p.134 21172 The evidence for supersymmetry keeps failing to appear
08 p.144 21173 Supersymmetry says particles and superpartners were unities, but then split
08 p.150 21174 Dark matter must have mass, to produce gravity, and no electric charge, to not reflect light
08 p.158 21175 String theory might be tested by colliding strings to make bigger 'stringballs'
09 p.167 21176 In the Big Bang general relativity fails, because gravity is too powerful
09 p.169 21178 String theory is now part of 11-dimensional M-Theory, involving p-branes
09 p.169 21177 String theory offers a quantum theory of gravity, by describing the graviton
09 p.171 21179 Supersymmetric string theory can be expressed using loop quantum gravity
