Q1 Even in heights Muslims do pray which can be seen; in Trains they do which G who writes about the trains might have seen; even is car is parked on the highway and pray; then why a silly question here. To fill pages?
Q2 Poor soldiers cannot afford; those salaried class where tax is deducted may not afford; and your grandparents maintained well the kitchen being not modular; so it is a waste of money. Even after making it modular in India where water is spilled over, and not enough vent out, one has to recur more expenditures. 15th time page filler. Q3 Two boats moving in parallel paths close to one another risk colliding. Why? Bermulli principle is strictly followed? I stand corrected. Q3 KR It is not Bermulli ; *Bernoulli's principle* is a key concept in fluid dynamics <https://en.wikipedia.org/wiki/Fluid_dynamics> that relates pressure, speed and height. Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure <https://en.wikipedia.org/wiki/Static_pressure> or the fluid <https://en.wikipedia.org/wiki/Fluid>'s potential energy <https://en.wikipedia.org/wiki/Potential_energy>. The principle is named after the Swiss mathematician and physicist Daniel Bernoulli <https://en.wikipedia.org/wiki/Daniel_Bernoulli>, who published it in his book *Hydrodynamica <https://en.wikipedia.org/wiki/Hydrodynamica>* in 1738. Although Bernoulli deduced that pressure decreases when the flow speed increases, it was Leonhard Euler <https://en.wikipedia.org/wiki/Leonhard_Euler> in 1752 who derived *Bernoulli's equation* in its usual form.Bernoulli's principle can be derived from the principle of conservation of energy <https://en.wikipedia.org/wiki/Conservation_of_energy>. This states that, in a steady flow, the sum of all forms of energy in a fluid is the same at all points that are free of viscous forces. This requires that the sum of kinetic energy <https://en.wikipedia.org/wiki/Kinetic_energy>, potential energy and internal energy <https://en.wikipedia.org/wiki/Internal_energy> remains constant. Thus an increase in the speed of the fluid—implying an increase in its kinetic energy—occurs with a simultaneous decrease in (the sum of) its potential energy (including the static pressure) and internal energy. If the fluid is flowing out of a reservoir, the sum of all forms of energy is the same because in a reservoir the energy per unit volume (the sum of pressure and gravitational potential <https://en.wikipedia.org/wiki/Gravitational_potential> *ρ* *g* *h*) is the same everywhere. The pressure difference creates a net force pushing the object or the fluid toward the low-pressure area. This principle is applied in airplane wings, sailboats, baseball curves, entrainment devices, and other real-life applications. But when you say side by side, what will cause the pressure variation so as to pull one boat towards the other? None, as control is effective in sailing. Even 2 planes go side by side on an Independence Day sky parade. Pressure does not pull; loss of the curvature control causes the spin. Fast bowlers in cricket do shine only one side on their pants; why? because one side retains the shine while the other side is roughened; less pressure off the rough side causes inswing better, spin better. Parallel sailing does not cause any turtle. Of course, where the two vessels whose sides has , different surfaces, one smoother and another rough, and the nature , the wind , go berserk, and the wind blows in between the vessels, then pressure might vary, and the weaker might turtle and might hit the other vessel. Until then, nothing will go wrong. Q4 Will granite chip or crack? *note- I have observed very slight breaks in the edges of few granite slabs laid 17 years back in my* home . Whether manufacturing defect noted recently or quality of granite or any other reason is not known. Laid by contractor. Q4 KR Granite will crack and hence costlier to maintain. Variation of Marble and Granite is taught by me but refused to be believed. Q5 Why was sand filled in the assembly hall of the Konark Sun Temple, and why is it being removed now after 119 years? Q5 KR Sand filling is a controversial subject in the history. Q6 Could life on Earth have come from Venus? Venus used to be in the habitable zone and probably had oceans, so is it possible space debris transported it here? Q6 KR I need not write anything. The author said it as it is not. Then why so many pages fillers? Q7 Why do most of the symptoms like stroke, heart attack, and sugar spikes occur late at night? Q7 KR The circadian theory is taken up but did not present the medical version approved. Suppose if a man is kept during day time only, will the effect (circadian) can be defeated? NO. The best method of measuring the circadian rhythm includes monitoring the core body temperature and salivary/plasma melatonin levels. A rating scale, morningness-eveningness questionnaire (MEQ), can also be utilized to assess the circadian pattern. A non-invasive, but less common monitoring technique, actimetry, examines a person’s activity/rest cycle. Other long-term studies include the use of polysomnography and EEGs. An individual’s environmental cues, also known as zeitgebers, drive the endogenous process of the circadian rhythm. The relationship between physiological and behavioural cues (timing of sleep, meals, work/social interactions) impact the timing of the sleep-wake cycle. Disturbances in an individual’s sleep cycle can have a significant detrimental effect on their overall health. Non-rhythmic regulations of core body temperature, cortisol levels, and melatonin secretion are all indicators of irregularities. Since fluctuations in body temperature occur systematically during the sleep/wake cycle, deviations from this cycle can indicate the onset of a disease or the nefarious presence of some external factor. Under the control of the SCN via the paraventricular nucleus of the hypothalamus, cortisol secretion is rhythmic, so the overproduction of cortisol can inhibit one’s ability to induce sleep. Likewise, the underproduction of melatonin can negatively impact one’s ability to fall asleep. Sleep disorders linked to the circadian rhythm are often overlooked and can have detrimental effects on the human body. Circadian rhythm sleep disorders typically manifest as a misalignment between a person’s sleep timeline and the physical/social 24-hour environmental cycle. The 2 more prevalent sleep disorders of circadian rhythms are advanced sleep phase (early onset, common in elders) and delayed sleep phase (later onset, common in adolescents). These 2 diagnoses often get misdiagnosed as insomnia or excessive sleepiness but are distinctly different disorders resulting from disruptions in the synchronization of the sleep/wake cycle. People prone to developing circadian rhythm sleep disorders include individuals who work evening shifts or have irregular shift schedules and the blind. Blind individuals are susceptible to develop these types of disorders because of their body’s inability to perceive light, and therefore, establish circadian rhythms. While blind individuals do have a pathway in the brain that functions as their body clock, roughly half of blind individuals experience non-24-hour sleep-wake rhythm disorder, during which their sleep cycles get later every night, jumps around, or results in waking up later in the day. Irregular sleep-wake rhythm disorder, although rare, is found in people suffering from neurological disorders such as dementia, mental retardation, and brain damage. This disorder is characterized by excessively engaging in napping during both the day and night, having no distinct sleep pattern, difficulty in maintaining hard sleep, grogginess when awake, and an inability to maintain the amount of sleep needed for their age. Shift work disorder occurs when people have early-morning, night, or rotating shifts that disturb their normal 24-hour sleep/wake cycle. These individuals experience extreme fatigue and are at a greater risk for work place injuries and cognitive impairment due to an average of 4 hours or less sleep per night. When traveling across multiple time zones, a disassociation of the internal clock and environmental time can result in what is known as jet lag. Artificial illumination from computers, televisions, cell phones, and other electronic devices can also interfere with the body’s ability to maintain proper circadian rhythms. Mounting evidence demonstrates the link between circadian rhythmicity and mood regulation disorders, such as seasonal affective disorder. Symptoms typical in patients suffering from depression can often be linked to that individual’s disruption of circadian rhythms. Treatment of these disorders includes a pharmacological approach in combination with light therapy and creating an effective, stable sleep/wake schedule. HENCE IT IS NOT Day night concept; it is certain provocative symptoms, lead to circadian theory; so, things do happen; this is the SCIENCE.
