Constants of Nature John D Barrow
Main Theme subjects Anti- anthropomorphic [ human centered ] measurement
Measuring based on hands, to central standards in Paris, to properties of nature
The inevitability of constants of nature Einstein on Constants
how came the values of the constants of nature? another thought of Einstein ; Was it pre-ordained, can they change?
Why these specific odd values? Do they define current state and can life and the universe
exist with other values?
Unified theory of reality theory of everything quantum mechanics – theory of the Very Small ++ general relativity to gether – Theory of the Very Large The universe must be a minimal age for it to have observers.
Atleast 1 generation of stars need to have died emitting complex elements that result in life on the universe 10 Billion years for that

The constants of nature
H > Plancks constant
Constant of action / the smallest quantum through which energy can be supplemented or deducted.
Planck time [10 ^ -43 splanck length [10 ^-40 m]
planck temperature [10^-23 c]
K = Boltzmann constant
energy to temperature conversion
α > The fine structure constant
~ 137
Mp / Me > ratio of the proton mass to the
electron mass
C > the speed of light1 wavelength of Cd red light 6438.8 Angstroms
G > gravitation constant as described
by Einstein
4 fundamental forces of nature Gravitation Electro magnetic force Strong Nuclear force Weak Nuclear force

Brought the pattern of numbers into constants | calculated 10^80 as the number of particles in the
universe / described that there is something symphonic about natural values like 10^80, 10^40
etc…
Paul Dirac stipulated that the constants could vary especially
G inversely as the expanding universe

disposed diracs changing constant hypothesis extrapolating to pre-cambrian times / Father of the
nuclear bomb along with Stan Ulam

Who defined the anthropic theory that we need to be in a specific universe to observe it therefore are conditioned by our context.
Also that universe needs to have aged a minimum time to generate the complex elements and therefore life, before there
can be any observerAnother form of anthropocentric theory is defined
Some good quotations
Life is what the least of us make the most of us think what the least of us make the
most of
Douglas adams / HHGTTG
At the end of the universe you would have to use the pass tense a lot, everythings been done you
know!

Can there be a universal wave theory
?
Expanding & Expanse of Universe? While the universe is described as an expanding universe
emanating from a big bang based on the observation of galaxies moving apart based on red shift, are we restricting ourselves to the visible universe and thereby defining the overall universe?
Could the universe be much bigger?
Constants Change? How does it propagate? On the observation that constants change over a period
albeit slowly, how does the change propagate? Instantaneously ? or across time and universally or locally? If it does propagate instantaneously then information and therefore the change in condition happens much faster than light?
What is Gravity / Graviton Gravity has a large wavelength tending to infinity. Would that
mean that gravity applies between bodies faster than light or would it also need time as much as light to have effect on adjacent objects?
Multi-dim Universe about a 3 + 1 dimension universe, the higher dimensions
are considered to be extremely local in the magnitude of 10^-30 how would that effect the general understanding of the universe
What are the constants of nature? How did science evolve to understand the constants of
nature?
What is not anthropocentric? Is idol worship bad ? But what about text and language itself? What about counting and numbers? what is not anthropomorphic? truly?
