take that

In traditional Chinese culture, qi (氣 / 气; Pinyin qì, Wade-Giles ch'i Jyutping hei; Korean gi; Japanese ki; Vietnamese khí; pronounced IPA: [tɕʰi˥˩] in Standard Mandarin) is an active principle forming part of any living thing.
It is frequently translated as "energy flow," and is often compared to Western notions of energeia or élan vital (vitalism) as well as the yogic notion of prana. The literal translation is "air," "breath," or "gas" (compare the original meaning of Latin spiritus "breathing"; or the Common Greek πνεῦμα, meaning "air," "breath," or "spirit"; and the Sanskrit term prana, "breath" ).

"Breathing is one of the few bodily functions which, within limits, can be controlled both consciously and unconsciously."

".....The most important function of breathing is gas exchange (of oxygen and carbon dioxide). Thus the control of respiration is centered primarily on how well this is achieved by the lungs."

take a breather, we all need one every now and again....


Example of a breather solution for the sine-Gordon equation
The sine-Gordon equation is the nonlinear dispersive partial differential equation

with the field u a function of the spatial coordinate x and time t.
An exact solution found by using the inverse scattering transform is^[2]:

which, for ω <>, is periodic in time t and decays exponentially when moving away from x = 0.
in other words....


take your eyes from the clock turn off the alarm wait to be awakened by the sunlight streaming through the window the squirrels scratching at the window the green flashes as light bounces off the leaves of the tree dazzling outside the window

lighten up the day take a book take an equation take a pen take a moment take your time

is it more easy if you know how or if you know why?
