Quotes About Constants

If the fine structure constant, that governs the strength of electromagnetic forces, were changed by more than 4 per cent or the strong force by more than 0.4 of one per cent then the production of carbon or oxygen would be reduced by factors of between 30 and 1000.

A change of more than 0.4 per cent in the constants governing the strength of the strong nuclear force or more than 4 per cent in the fine structure constant would destroy almost all carbon or almost all oxygen in every star.

I guess law was always interesting to me because you deal with constants. I like to deal with constants, abstracts, constants and reason and ration, rational approaches to things. I don't know, I never really thought why I wanted to study law. But if you ask me whether I would do it again, absolutely.

Many of the fundamental physical constants-which as far as one could see, God could have given any value He liked-are in fact very precised adjusted, or fine-tuned, to produce the only kind of Universe that makes our existence possible.

Knowledge – if it is profound – never changes: only its décor varies. Love continues without Venus, was without Mars, and if the gods no longer intervene in events, those events are neither more explicable nor less disconcerting: the paraphernalia of formulas merely replaces the pomp of the old legends, without the constants of human life being thereby modified, science apprehending them no more intimately than poetic narratives.

Symmetries are the playing field on which the physical world works and which determine the rules of the game. The symmetries of nature determine for us things that remain constant, that can't be changed. Those are the guideposts in physics, the quantities like energy and momentum.

while many of the absolutes we cling to are social constructs (varying across cultures and over time), behind these changing constructs we also find some universal human constants.

La mayoría de las constantes fundamentales que aparecen en las teorías están ajustadas con tanta precisión que si su valor cambiara aunque sólo fuera ligeramente el universo sería cualitativamente diferente, y en la mayoría de los casos resultaría inadecuado para el desarrollo de la vida.

The uncertainty of life got me thinking about the importance of constants in our lives.

Some properties should not be changed. The Answer to Life, the Universe, and Everything is 42, and you want it to stay that way. Error and status flags will often be hard-coded into your classes. Although they should be publicly and statically available, client code should not be able to change them.

If anything runs deeper than a mathematician's love of variables, it's a scientist's love of constants.

I'll grant the random access to my heart, Thoul't tell me all the constants of thy love; And so we two shall all love's lemmas prove And in our bound partition never part.

The constants that I look for are a love of light and a determination to trace some moral chain of being.

Macro substitution is almost never necessary in C++. Use const (§7.5), constexpr (§2.2.3, §10.4), enum or enum class (§8.4) to define manifest constants, inline (§12.1.5) to avoid function-calling overhead, templates (§3.4, Chapter 23) to specify families of functions and types, and namespaces (§2.4.2, §14.3.1) to avoid name clashes.

The uncertainty of life got me thinking about the importance of constants in our lives.

Scientists have, in fact, assembled long lists of scores of such "happy cosmic accidents." When faced with this imposing list, it's shocking to find how many of the familiar constants of the universe lie within a very narrow band that makes life possible. If a single one of these accidents were altered, stars would never form, the universe would fly apart, DNA would not exist, life as we know it would be impossible, Earth would flip over or freeze, and so on.

There is something stunningly narrow about how the Anthropic Principle is phrased. Yes, only certain laws and constants of nature are consistent with our kind of life. But essentially the same laws and constants are required to make a rock. So why not talk about a Universe designed so rocks could one day come to be, and strong and weak Lithic Principles? If stones could philosophize, I imagine Lithic Principles would be at the intellectual frontiers.

In 1899, the father of quantum theory, a German physicist named Max Planck, realized that there was one and only one way to combine these fundamental constants to produce a scale of length.

While twentieth-century physicists were not able to identify any convincing mathematical constants underlying the fine structure, partly because such thinking has normally not been encouraged, a revolutionary suggestion was recently made by the Czech physicist Raji Heyrovska, who deduced that the fine structure constant, ...really is defined by the [golden] ratio ....

We have found that the values of the constants of nature have not been fine-tuned for life by accident, but that these values are constrained by and logically follow from the fundamental space-time organization of the Cosmic Tree of Life.

The Doctor' is the kind of character - because the guest cast is changing all the time, there are very few constants in the show, so the 'Doctor'- when you're there, you're in it a lot. You're speaking a lot.

There is a remarkably close parallel between the problems of the physicist and those of the cryptographer. The system on which a message is enciphered corresponds to the laws of the universe, the intercepted messages to the evidence available, the keys for a day or a message to important constants which have to be determined. The correspondence is very close, but the subject matter of cryptography is very easily dealt with by discrete machinery, physics not so easily." —Alan Turing

I learned from my dad that change and experimentation are constants and important. You have to keep trying new things.

In general, exchange reactions for the lighter isotopes have equilibrium constants sufficiently different from unity, so that the ratios of concentrations of the isotopes in two compounds which are in equilibrium differ by a few per cents in nearly all cases.
