"Canyons of the Colorado" by J. W. Powell
A fine idea, no doubt, but quite as impracticable as Shigalov's theories, which you referred to just now so contemptuously.
"The Possessed" by Fyodor Dostoevsky
These were the doctrines of the Stoics, from whose sublime and impracticable philosophy they seemed naturally enough to flow.

But this proved impracticable; the placard must remain where it stood for the behoof of other invalids.
"The Wrong Twin" by Harry Leon Wilson
Most of his correspondents thought that the idea was hopelessly impracticable.
"Human Nature In Politics" by Graham Wallas
The gates of Belen and San Antonio were beset by obstacles even more impracticable.

And in this respect he is the type of the impracticable and mischief-making class of reformers numerous in this country.
"Continental Monthly, Vol. 5, Issue 2, February, 1864" by Various
Among other motives for an early campaign, Colonel Washington had urged the impracticability of detaining the Indians.

And crowned his hair with flowers -
No easier nor no quicker passed
The impracticable hours.

In news:

More importantly, many unpalatable or impracticable things can help people lose weight, including eating woodchips or wrestling bears.

In science:

This type of configuration is suitable for counter designs requiriring a large geometrical acceptance {detection area}⊗{angular range}, for which the use of focussing devices is severely limited or even impracticable, provided the required velocity resolution is not too high.
Experimental study of a proximity focusing Cherenkov counter prototype for the AMS experiment
It is equivalent to giving a formal expression of qs (V , T ) that is impracticable to handle for large size clusters.
Clusters in Simple Fluids
It becomes noticeable that SWRs’ values are excessively high at the frequencies of 900 and 1111 [MHz]. Consequently, the utilization of the antenna at the pre-mentioned frequencies is impracticable.
"D-Dimond1", Prototype Antenna RGA-05
These numerical techniques are efficient and yield accurate estimates of high percentiles of sums of random variables provided that these are not too heavy-tailed: their computational cost increases as the tails of the probability distribution become heavier, and eventually become impracticable.
Percentiles of sums of heavy-tailed random variables: Beyond the single-loss approximation
Snapshots are poorly suited to this task, as they are severely limited by the dynamic range of the data, which generally makes interpolation impossible unless the interval between snapshots is made impracticably small.
MODEST-1: Integrating Stellar Evolution and Stellar Dynamics
This makes the aforementioned exact relation unwieldy and impracticable to say the least.
Computers and Liquid State Statistical Mechanics
The same effect could be achieved with an independent laser beam used from the right on the 2MC, but it would require impracticably high powers.
Trapping and Cooling a mirror to its quantum mechanical ground state
A direct measurement of the relevant mechanical losses at the frequencies of the detection band of IGWDs is often impracticable as the losses are typically extremely low in this region. A more feasible approach is to determine the mechanical losses at the resonances of the test masses.

For problems with a high dimensional θ this inefficiency is likely to make the application of a rejection type algorithm impracticable.
Approximate Bayesian computation (ABC) gives exact results under the assumption of model error
Often it is easy to simulate from the models but calculating the likelihood of the data, even using computationally-intensive methods, is impracticable.
Constructing Summary Statistics for Approximate Bayesian Computation: Semi-automatic ABC
The use of ABC initially became popular within population genetics, where simulation from a range of population genetic models is possible using the coalescent (Kingman, 1982), but where calculating likelihoods is impracticable for realistic sized data sets.
Constructing Summary Statistics for Approximate Bayesian Computation: Semi-automatic ABC
However fitting the linear model with the resulting 4 × 104 exaplanatory variables is impracticable.
