1. Philosophy / A. Wisdom / 2. Wise People
Why can't a wise man doubt everything? [Montaigne]
1. Philosophy / A. Wisdom / 3. Wisdom Deflated
No wisdom could make us comfortably walk a wide beam if it was high in the air [Montaigne]
3. Truth / A. Truth Problems / 3. Value of Truth
Virtue is the distinctive mark of truth, and its greatest product [Montaigne]
7. Existence / A. Nature of Existence / 3. Being / c. Becoming
Bergson was a rallying point, because he emphasised becomings and multiplicities [Bergson, by Deleuze]
7. Existence / D. Theories of Reality / 2. Reality
We lack some sense or other, and hence objects may have hidden features [Montaigne]
12. Knowledge Sources / E. Direct Knowledge / 4. Memory
Bergson showed that memory is not after the event, but coexists with it [Bergson, by Deleuze]
13. Knowledge Criteria / D. Scepticism / 1. Scepticism
Sceptics say there is truth, but no means of making or testing lasting judgements [Montaigne]
15. Nature of Minds / A. Nature of Mind / 1. Mind / d. Location of mind
The soul is in the brain, as shown by head injuries [Montaigne]
27. Natural Reality / A. Classical Physics / 1. Mechanics / d. Gravity
Gravity is unusual, in that it always attracts and never repels [New Sci.]
27. Natural Reality / B. Modern Physics / 1. Relativity / b. General relativity
In the Big Band general relativity fails, because gravity is too powerful [New Sci.]
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / a. Electrodynamics
Photons have zero rest mass, so virtual photons have infinite range [New Sci.]
Quantum electrodynamics incorporates special relativity and quantum mechanics [New Sci.]
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / b. Fields
In the standard model all the fundamental force fields merge at extremely high energies [New Sci.]
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / c. Electrons
Electrons move fast, so are subject to special relativity [New Sci.]
27. Natural Reality / B. Modern Physics / 3. Chromodynamics / a. Chromodynamics
The strong force is repulsive at short distances, strong at medium, and fades at long [New Sci.]
The strong force binds quarks tight, and the nucleus more weakly [New Sci.]
Gluons, the particles carrying the strong force, interact because of their colour charge [New Sci.]
27. Natural Reality / B. Modern Physics / 3. Chromodynamics / b. Quarks
Quarks in threes can build hadrons with spin or with spin 3/2 [New Sci.]
Classifying hadrons revealed two symmetry patterns, produced by three basic elements [New Sci.]
Three different colours of quark (as in the proton) can cancel out to give no colour [New Sci.]
27. Natural Reality / B. Modern Physics / 4. Standard Model / b. Standard model
The four fundamental forces (gravity, electromagnetism, weak and strong) are the effects of particles [New Sci.]
The weak force explains beta decay, and the change of type by quarks and leptons [New Sci.]
Three particles enable the weak force: W+ and W- are charged, and Z is not [New Sci.]
The weak force particles are heavy, so the force has a short range [New Sci.]
Why do the charges of the very different proton and electron perfectly match up? [New Sci.]
The Standard Model cannot explain dark energy, survival of matter, gravity, or force strength [New Sci.]
27. Natural Reality / B. Modern Physics / 4. Standard Model / c. Particle properties
Fermions, with spin , are antisocial, and cannot share quantum states [New Sci.]
Spin is akin to rotation, and is easily measured in a magnetic field [New Sci.]
Quarks have red, green or blue colour charge (akin to electric charge) [New Sci.]
Particles are spread out, with wave-like properties, and higher energy shortens the wavelength [New Sci.]
Spin is a built-in ration of angular momentum [New Sci.]
27. Natural Reality / B. Modern Physics / 4. Standard Model / d. Mass
Gravitional mass turns out to be the same as inertial mass [New Sci.]
The mass of protons and neutrinos is mostly binding energy, not the quarks [New Sci.]
27. Natural Reality / B. Modern Physics / 4. Standard Model / e. Protons
Top, bottom, charm and strange quarks quickly decay into up and down [New Sci.]
Neutrons are slightly heavier than protons, and decay into them by emitting an electron [New Sci.]
27. Natural Reality / B. Modern Physics / 4. Standard Model / f. Neutrinos
Neutrinos were proposed as the missing energy in neutron beta decay [New Sci.]
Only neutrinos spin anticlockwise [New Sci.]
27. Natural Reality / B. Modern Physics / 4. Standard Model / g. Anti-matter
Standard antineutrinos have opposite spin and opposite lepton number [New Sci.]
27. Natural Reality / B. Modern Physics / 5. Unified Models / a. Electro-weak unity
The symmetry of unified electromagnetic and weak forces was broken by the Higgs field [New Sci.]
27. Natural Reality / B. Modern Physics / 5. Unified Models / b. String theory
String theory is now part of 11-dimensional M-Theory, involving p-branes [New Sci.]
String theory offers a quantum theory of gravity, by describing the graviton [New Sci.]
String theory might be tested by colliding strings to make bigger 'stringballs' [New Sci.]
Supersymmetric string theory can be expressed using loop quantum gravity [New Sci.]
27. Natural Reality / B. Modern Physics / 5. Unified Models / c. Supersymmetry
Supersymmetry says particles and superpartners were unities, but then split [New Sci.]
Supersymmetry has extra heavy bosons and heavy fermions [New Sci.]
The evidence for supersymmetry keeps failing to appear [New Sci.]
Only supersymmetry offers to incorporate gravity into the scheme [New Sci.]
27. Natural Reality / C. Space-Time / 1. Space / d. Substantival space
The Higgs field means even low energy space is not empty [New Sci.]
27. Natural Reality / D. Cosmology / 8. Dark Matter
Dark matter must have mass, to produce gravity, and no electric charge, to not reflect light [New Sci.]
