Constants of Nature John D Barrow

Page 2: constants nature John Barrow A Book Summary

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?

Page 3: constants nature John Barrow A Book Summary

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

Page 8: constants nature John Barrow A Book Summary

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]

Page 9: constants nature John Barrow A Book Summary

K = Boltzmann constant

energy to temperature conversion

Page 10: constants nature John Barrow A Book Summary

α > The fine structure constant

~ 137

Page 11: constants nature John Barrow A Book Summary

Mp / Me > ratio of the proton mass to the

electron mass

Page 12: constants nature John Barrow A Book Summary

C > the speed of light1 wavelength of Cd red light 6438.8 Angstroms

Page 13: constants nature John Barrow A Book Summary

G > gravitation constant as described

by Einstein

Arthur eddington

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…

Page 20: constants nature John Barrow A Book Summary

Paul Dirac stipulated that the constants could vary especially

G inversely as the expanding universe

nuclear bomb along with Stan Ulam

Robert Dicke

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

Page 24: constants nature John Barrow A Book Summary

Life is what the least of us make the most of us think what the least of us make the

most of

At the end of the universe you would have to use the pass tense a lot, everythings been done you

know!

[ on human centric systems]

There was a crooked man who built a crooked house

Page 28: constants nature John Barrow A Book Summary

Can there be a universal wave theory

?

Page 29: constants nature John Barrow A Book Summary

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?

Page 30: constants nature John Barrow A Book Summary

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?

Page 31: constants nature John Barrow A Book Summary

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?

Page 32: constants nature John Barrow A Book Summary

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

Page 33: constants nature John Barrow A Book Summary

What are the constants of nature? How did science evolve to understand the constants of

nature?

Page 34: constants nature John Barrow A Book Summary

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?
