idea number gives full details    |    back to list of philosophers    |     expand these ideas
7. Existence / A. Nature of Existence / 7. Reason for Existence
Current physics says matter and antimatter should have reduced to light at the big bang
CP violation shows a decay imbalance in matter and antimatter, leading to matter's dominance
14. Science / A. Basis of Science / 4. Prediction
A system can infer the structure of the world by making predictions about it
15. Nature of Minds / C. Capacities of Minds / 3. Abstraction by mind
Neural networks can extract the car-ness of a car, or the chair-ness of a chair
18. Thought / A. Modes of Thought / 6. Rationality
No one has yet devised a rationality test
18. Thought / A. Modes of Thought / 7. Intelligence
About a third of variation in human intelligence is environmental
People can be highly intelligent, yet very stupid
18. Thought / B. Mechanics of Thought / 1. Psychology
Psychologists measure personality along five dimensions
26. Natural Theory / B. Concepts of Nature / 3. Space / a. Space
Hilbert Space is an abstraction representing all possible states of a quantum system
26. Natural Theory / B. Concepts of Nature / 4. Time / e. Existence of time
Quantum states are measured by external time, of unknown origin
Quantum theory relies on a clock outside the system - but where is it located?
Entropy is puzzling, so we may need to build new laws which include time directionality
Entropy is the only time-asymmetric law, so time may be linked to entropy
26. Natural Theory / B. Concepts of Nature / 5. Space-Time
Relativity makes time and space jointly basic; quantum theory splits them, and prioritises time
Space-time may be a geometrical manifestation of quantum entanglement
27. Natural Reality / A. Physics / 1. Matter / i. Modern matter
84.5 percent of the universe is made of dark matter
27. Natural Reality / A. Physics / 1. Matter / l. Quantum theory
The Schrödinger equation describes the evolution of an object's wave function in Hilbert space
27. Natural Reality / A. Physics / 1. Matter / m. String theory
It is impossible for find a model of actuality among the innumerable models in string theory
String theory needs at least 10 space-time dimensions
In string theory space-time has a grainy indivisible substructure
27. Natural Reality / A. Physics / 5. Light
Light moves at a constant space-time speed, but its direction is in neither space nor time
27. Natural Reality / B. Chemistry / 1. Chemistry
We are halfway to synthesising any molecule we want
27. Natural Reality / B. Chemistry / 3. Periodic Table
Chemistry just needs the periodic table, and protons, electrons and neutrinos
27. Natural Reality / D. Cosmology / 5. General Relativity
General relativity predicts black holes, as former massive stars, and as galaxy centres
Black holes have entropy, but general relativity says they are unstructured, and lack entropy
Einstein's merging of time with space has left us confused about the nature of time
