It is difficult to reconstruct the primeval fears of man.

And Zen Buddhism, though it is extremely difficult to understand how these internal contradictions are reconciled, helps them in their struggle to achieve personal salvation through sexual release.

The release, the freedom, involved in loving another is either terribly difficult or else absolutely impossible ; ;

moreover, it is increasingly difficult to distinguish between the two.

The making of distinctions, like the perception of the great distinctions made, is an inordinately difficult business.

Since civilizational change is the most difficult to perceive and analyze, it seldom is given adequate attention.

It is more difficult with Faulkner than with most authors to say what is the extent and what is the source of his knowledge.

It seems quite obvious that all the really difficult tasks of human beings arise from the fact that man is not one, but many.

The problem is rather to find out what is actually happening, and this is especially difficult for the reason that `` we are busily being defended from a knowledge of the present, sometimes by the very agencies -- our educational system, our mass media, our statesmen -- on which we have had to rely most heavily for understanding of ourselves ''.

But however we come, finally, to explain and account for the present, the truth we are trying to expose, right now, is that the makers of constitutions and the designers of institutions find it difficult if not impossible to anticipate the behavior of the host of all their enterprises.

It is not difficult to anticipate circumstances in which negative tensions will cumulate ; ;

In the wide range of experiences common to our earth-bound race none is more difficult to manage, more troublesome, and more enduring in its effects than the control of love and hate.

Accordingly we may speak of the Platonism peculiar to Shelley's poems or the type of Stoicism present in Henley's `` Invictus '', and we may find that describing such Platonism or such Stoicism and contrasting each with other expressions of the same attitude or mode of thought is a difficult and challenging enterprise.

It is difficult to say what Thompson expected would come of their relationship, which had begun so soon after his emotions had been stirred by Maggie Brien, but when Katie wrote on April 11, 1900, to tell him that she was to be married to the Rev. Godfrey Burr, the vicar of Rushall in Staffordshire, the news evidently helped to deepen his discouragement over the failure of his hopes for a new volume of verse.

This, naturally, will be difficult to do since both the archaeological and place-name evidence in this period, with some fortunate exceptions, is insufficient for precise chronological purposes.

A study of the hydrogen line profiles indicates that a measurement of these profiles can be used to calculate a temperature for the arc plasma that is reliable to about Af percent.

Sometimes it is necessary to roughly calculate the square inch area of the opening but the calculation can usually be made with sufficient accuracy that it won't affect the final computation.

Therefore a naive algorithm to calculate the estimated variance is given by the following:

Only the product is required to calculate planetary positions for an ephemeris, which explains why ephemerides are calculated in astronomical units and not in SI units.

It is used to calculate income tax.

Originally based on the date used to calculate the age of fruit trees for tithing as mandated in Leviticus 19: 23 – 25, the holiday now is most often observed by planting trees, or raising money to plant trees.

In 1738 The Dutch-Swiss mathematician Daniel Bernoulli published Hydrodynamica, in which he described the fundamental relationship among pressure, density, and velocity ; in particular Bernoulli's principle, which is one method to calculate aerodynamic lift.

When the particles are in great motion, they produce a Doppler shift for measuring wind speed in the laser light, which is used to calculate the speed of the particles, and therefore the air around the anemometer.

The assumption that there is no arbitrage is used in quantitative finance to calculate a unique risk neutral price for derivatives.

In baseball, an at bat ( AB ) or time at bat is used to calculate certain statistics, including batting average, on base percentage, and slugging percentage.

Bernoulli's formula is sometimes called Faulhaber's formula after Johann Faulhaber who also found remarkable ways to calculate sum of powers.

Classical physics draws a distinction between particles and energy, holding that only the latter exhibit waveform characteristics, whereas quantum mechanics is based on the observation that matter has both wave and particle aspects and postulates that the state of every subatomic particle can be described by a wavefunction — a mathematical expression used to calculate the probability that the particle, if measured, will be in a given location or state of motion.

It is summarized by the sentence " Shut up and calculate !".

A particularly important objective, called computational thermochemistry, is to calculate thermochemical quantities such as the enthalpy of formation to chemical accuracy.

Since it is time-consuming to calculate the energy for a molecule, it is even more time-consuming to calculate them for the entire list of points in the Brillouin zone.

* CPAN Dependencies, which combines data from META. yml files and the CPAN testers to graphically show a module's dependencies and attempt to calculate how likely it is to work on a particular platform.

The formula used to calculate the final scores is a weighted sum of the votes.

There is, however, no formula to calculate compression ratio based on cylinder pressure.

Paired with the problem are any number of algorithms that can be used to solve the problem, that is, to calculate the solution.

The two oldest printed Chinese calendars are dated 877 and 882 ; they were found at the Buddhist pilgrimage site of Dunhuang ; Patricia Ebrey writes that it is no surprise that some of the earliest printed items were calendars, since the Chinese found it necessary to calculate and mark which days were auspicious and which were not.

The usual objective of a control theory is to calculate solutions for the proper corrective action from the controller that result in system stability, that is, the system will hold the set point and not oscillate around it.
