Single Idea 21183
[filed under theme 27. Natural Reality / A. Classical Physics / 2. Thermodynamics / a. Energy
]
Full Idea
The Laws of Thermodynamics introduced the concepts of entropy and work; put simply, how much useful energy you can really get out of a steam engine.
Gist of Idea
Thermodynamics introduced work and entropy, to understand steam engine efficiency

A Reaction
The point of science by this stage was to introduce measurable and quantifiable concepts

20 ideas

21181
|
Relativity and Quantum theory give very different accounts of forces
[Hesketh]
|
|
21180
|
Electrons are fundamental and are not made of anything; they are properties without size
[Hesketh]
|
|
21182
|
Quantum mechanics is our only theory, and is very precise, and repeatedly confirmed
[Hesketh]
|
|
21184
|
Physics was rewritten to explain stable electron orbits
[Hesketh]
|
|
21183
|
Thermodynamics introduced work and entropy, to understand steam engine efficiency
[Hesketh]
|
|
21186
|
Quarks rush wildly around in protons, restrained by the gluons
[Hesketh]
|
|
21185
|
Colour charge is positive or negative, and also has red, green or blue direction
[Hesketh]
|
|
21188
|
Quarks and leptons have a weak charge, for the weak force
[Hesketh]
|
|
21189
|
Electrons may have smaller components, bound by a new force
[Hesketh]
|
|
21187
|
Virtual particles can't be measured, and can ignore the laws of physics
[Hesketh]
|
|
21190
|
'Space' in physics just means location
[Hesketh]
|
|
21191
|
Photons are B and W° bosons, linked by the Higgs mechanism
[Hesketh]
|
|
21192
|
Neutrinos only interact with the weak force, but decays produce them in huge numbers
[Hesketh]
|
|
21193
|
The universe is 68% dark energy, 27% dark matter, 5% regular matter
[Hesketh]
|
|
21194
|
The Standard Model omits gravity, because there are no particles involved
[Hesketh]
|
|
21195
|
In Supersymmetry the Standard Model simplifies at high energies
[Hesketh]
|
|
21198
|
If a cosmic theory relies a great deal on fine-tuning basic values, it is probably wrong
[Hesketh]
|
|
21196
|
To combine the forces, they must all be the same strength at some point
[Hesketh]
|
|
21197
|
Standard Model forces are one- two- and three-dimensional
[Hesketh]
|
|
21199
|
Spinning electric charge produces magnetism, so all fermions are magnets
[Hesketh]
