A Stirling engine in the microworld: In a normal-sized engine, a gas expands and contracts at different temperature and thus moves a piston in a cylinder. Physicists in Stuttgart have created this work cycle with a tiny plastic bead that they trapped in the focus of a laser field.

If it sputters, this is caused by the thermal motions of the smallest particles, which interfere with its running. Researchers at the University of Stuttgart and the Stuttgart-based Max Planck Institute for Intelligent Systems have now observed this with a heat engine on the micrometre scale. They have also determined that the machine does actually perform work, all things considered. Although this cannot be used as yet, the experiment carried out by the researchers in Stuttgart shows that an engine does basically work, even if it is on the microscale. This means that there is nothing, in principle, to prevent the construction of highly efficient, small heat engines.
"We've developed the world's smallest steam engine, or to be more precise the smallest Stirling engine, and found that the machine really does perform work," says Clemens Bechinger. "This was not necessarily to be expected, because the machine is so small that its motion is hindered by microscopic processes which are of no consequence in the macroworld." The disturbances cause the micromachine to run rough and, in a sense, sputter.
The laws of the microworld dictated that the researchers were not able to construct the tiny engine according to the blueprint of a normal-sized one. In the heat engine invented almost 200 years ago by Robert Stirling, a gas-filled cylinder is periodically heated and cooled so that the gas expands and contracts. This makes a piston execute a motion with which it can drive a wheel, for example.
"We successfully decreased the size of the essential parts of a heat engine, such as the working gas and piston, to only a few micrometres and then assembled them to a machine," says Valentin Blickle. The working gas in the Stuttgart-based experiment thus no longer consists of countless molecules, but of only one individual plastic bead measuring a mere three micrometres (one micrometre corresponds to one thousandth of a millimetre) which floats in water. Since the colloid particle is around 10,000 times larger than an atom, researchers can observe its motion directly in a microscope.
The physicists replaced the piston, which moves periodically up and down in a cylinder, by a focused laser beam whose intensity is periodically varied. The optical forces of the laser limit the motion of the plastic particle to a greater and a lesser degree, like the compression and expansion of the gas in the cylinder of a large heat engine. The particle then does work on the optical laser field. In order for the contributions to the work not to cancel each other out during compression and expansion, these must take place at different temperatures. This is done by heating the system from the outside during the expansion process, just like the boiler of a steam engine. The researchers replaced the coal fire of an old-fashioned steam engine with a further laser beam that heats the water suddenly, but also lets it cool down as soon as it is switched off.
The fact that the Stuttgart machine runs rough is down to the water molecules which surround the plastic bead. The water molecules are in constant motion due to their temperature and continually collide with the microparticle. In these random collisions, the plastic particle constantly exchanges energy with its surroundings on the same order of magnitude as the micromachine converts energy into work. "This effect means that the amount of energy gained varies greatly from cycle to cycle, and even brings the machine to a standstill in the extreme case," explains Valentin Blickle. Since macroscopic machines convert around 20 orders of magnitude more energy, the tiny collision energies of the smallest particles in them are not important.
The physicists are all the more astonished that the machine converts as much energy per cycle on average despite the varying power, and even runs with the same efficiency as its macroscopic counterpart under full load. "Our experiments provide us with an initial insight into the energy balance of a heat engine operating in microscopic dimensions. Although our machine does not provide any useful work as yet, there are no thermodynamic obstacles, in principle, which prohibit this in small dimensions," says Clemens Bechinger. This is surely good news for the design of reliable, highly efficient micromachines.
“I have searched all this earth: pools, ponds, lakes, streams, rivers, marshes, woods and difficult to access mountains - but still I do not see Sita. Sampati, the king of vultures, said that Sita was here in Ravana's abode, but still I am unable to see her.” (Hanuman, Valmiki Ramayana, Sundara Kand, 13.4-5)
In the above referenced verse from the Ramayana Hanuman lists the different areas of water in Lanka that have been searched already. The person he was looking for, 
Narayana follows a similar mindset. At this point, the question may be raised as to how anyone could ever be in a distressful situation if Narayana is the original father of creation. Why are their natural disasters, horrific tragedies, and seemingly unfair bouts of bad luck? The rule is that Narayana personally takes care of those who approach Him in earnest. In the Vedic tradition the living entities in the material world are often compared to inmates in a prison. In a free society, everyone has a choice of whether or not to abide by the law. Those who follow the law live in continued freedom, not having too many interactions with the law enforcers. Those who choose the rebel route have to be punished every now and then. The prison is not to be blamed for the punishment, and neither is the government. The choice was there from the very beginning, and because of the way freedom was exercised the negative consequences resulted.
Since the divine figures are incapable of fully masking their inherent features, Sita Devi remained tied to pure goodness, always choosing purity of association. 
Hanuman searched the mountains, marshes, woods, and pretty much entire land of Lanka and still couldn’t find Sita. After a while some doubt crept into his mind. Perhaps Sampati was mistaken in his assertion that Sita was in Lanka. Hanuman didn’t start off the search for Sita alone. Shri Rama and His younger brother 
Just imagine then how one feels when they hear about Hanuman and his level of dedication. He is the role model for every single person, for he isn’t even aware of how amazing he is. The quickest way to make progress in spiritual life is to see others succeeding at it. And what helps even more is to see people succeeding who are deemed to have very little chance at success. For instance, with Hanuman he had to face the strongest opposing elements in the Rakshasas of Lanka. Then he had to deal with the time factor, not knowing what Sita looked like, and most importantly, not knowing where she even was. Then he had to contend with mental demons, worries and concerns over failing. Who can imagine the pressure Hanuman was feeling, for he loved Rama so much and had yet to find His wife?
“Experience is gathered by hearing and seeing. One who is less intelligent gathers experience by seeing, and one who is more intelligent gathers experience by hearing.” (Shrila Prabhupada, Nectar of Instruction, 1 Purport)
So this seems plausible, no? But has anyone actually seen two monkeys produce a human being? Have we ever, in any scenario, seen a bunch of chemicals collide to produce life? Moreover, how does the evidence gathered from basic perception explain the phenomenon that is the sun? The sun has been burning since the beginning of time and it shows no signs of letting up. There aren’t fuel tankers driving to the sun nor is it even possible for human beings to come close to approaching the giant solar body, so intense is its heat. Rather than give the monkey the credit for creating the human being, why not worship the sun, who provides the light to maintain life on earth?

According to the evolution theory, the human species is the product of the fittest members of previous species mating. When operating under the mindset of following base instincts, however, where God consciousness is absent, the lower animals are actually superior. Say, for example, we have two laptop computers. Both machines have the exact same configuration, all the way down to the processors used and the operating system being run. The only difference is in the batteries. One machine has a battery life of five hours, while another machine’s has a life of one hour. The machine with the longer battery life is more efficient and thus superior. It can perform all of the same operations and do it without requiring a recharge of the battery every hour.
