Using a tip with a nano heat source that never touches the surface, scientists have shown how to heat a localized surface with no contact. The discovery could open the doors to heat-assisted data storage devices and nano thermometers. Explore further Engineers develop chip that converts wasted heat to usable energy Every year, the world’s data storage needs more than double. Understanding heat transfer on the nanoscale is imperative for fabricating technology that will affect nearly everyone living in first-world countries. All over the world, scientists are rushing to develop an alternative data storage system in an effort to increase the space that our information-overloaded society is running out of. One of the options, called thermally-assisted or heat-assisted data storage, works by using a laser to heat a data disc, which stabilizes the magnetic recording process by making it easier to write data when hot and retain data when subsequently cooled. The process overcomes a critical point that conventional magnetic recording devices will soon encounter, known as the superparamagnetic limit. As scientists increase data storage on conventional systems by making the room-temperature bits smaller, at a certain size the bits will become magnetically unstable, will fall out of place, and their information will vanish.In a recent study on heat transfer between a tip and a surface, scientists from France have made a significant step toward the development of heat-assisted data storage, as well as other applications. The team calculated the heat transfer between a silicon tip and a surface, which is dominated mostly by air conduction.“Heat transfer is well known at the macroscopic level (described by Fourier diffusion when collisions between molecules induce thermodynamic local equilibrium),” Pierre-Olivier Chapuis, coauthor of the recent paper in Nanotechnology, told PhysOrg.com. “Heat transfer can also be calculated in the pure ballistic regime (when there is no collision between molecules). But calculating heat transfer in the intermediate regime, when there are a few collisions, still remains a challenge.”In their experiment, the scientists used a tip with a heat source about 20 nanometers high hovering between zero and 50 nanometers above a surface. The heat transfer occurs when cold molecules in the air are heated when they come in contact with the hot tip, then fly to the disk surface, colliding sometimes with other molecules before reaching the surface. Using Boltzmann’s law on the movement of gas, the scientists proposed for the first time a heat distribution at this scale and levels of heat flux. The team showed that the heat transfer through the air takes only a few tens of picoseconds (10-12) seconds) to propagate from the tip to the surface when there is no contact. The scientists also found that below the height of 10 nanometers, a hot tip can heat a region with an edge of 35 nanometers while maintaining its shape; beyond this height, the shape is lost and the thermal spot increases significantly.Heat-assisted data storage products, which are generally predicted to break into the market around 2010, could achieve data density of trillions of bits (terabytes) per square inch, dwarfing the current density. Scanning thermal microscopy, which acts like a nano thermometer to sense temperature and thermal conductivity on the nanoscale, could also benefit from this non-contact, localized heat transfer method. “In thermally-assisted data storage, levels of heat flux are very important because you need to know if the increase of temperature is enough to reach the crtitical temperature (e.g. melting point),” said Sebastian Volz, coauthor of the study. “Scanning thermal microscopy can benefit from this work because it shows that, by reducing the heat source, you will probe more locally than what can be achieved now. Our work proposes a heat distribution in this field, which could help industrials design their devices.”Citation: Chapuis, Pierre-Olivier, Greffet, Jean-Jacques, Joulain, Karl and Volz, Sebastian.

Feynman wasnt joking Modeling quantum dynamics with ground state wavefunctions

first_img © 2013 Phys.org. All rights reserved. This allowed the researchers to specify a direct analogy to the convergence seen in ground state systems – that is, the rate of expansion convergence is inversely proportional to two-body interaction strength. “As far as we know,” McClean says, “nobody has used configuration interaction to do a time-dependent problem in the way we did in our paper.” Researcher Jarrod R. McClean discussed with Phys.org the research that he and his colleagues, Profs. John A. Parkhill and Alán Aspuru-Guzik, conducted. “In solving quantum dynamical problems prior to our findings, the large dimension and complexity of models in quantum mechanics make it very computationally expensive to perform dynamics simulations,” McClean tells Phys.org. “This means that only very short time scales can be examined with high accuracy. Moreover,” he points out, “previous attempts to utilize modern parallel computers have been hindered by strong spatial interactions within quantum systems.””One usually thinks of quantum information as a field that leads to the development of quantum computers,” Harvard’s Aspuru-Guzik notes. “It turns out that classical computing can benefit and learn from the ideas of quantum information. This application of Feynman’s clock to the challenging problem of time evolution is an example of this.”Traditional algorithms utilize parallelization in space, in which a supercomputer comprising many processors spatially distributes and advances the problem in single temporal increments. “What is less natural,” McClean continues, “is to think about the possibility of setting up a calculation that is parallel in time.” This means that the simulation at different points in time has to be simultaneously calculated on many processors. “That’s the focal point of our study,” McClean stresses. “We exploit the clock construction, which was originally designed to think about quantum computing for use in parallel computers.”McClean notes the importance of demonstrating their proposal’s accuracy convergence by applying the configuration interaction method – a linear variational method for solving the nonrelativistic Schrödinger equation. “We wanted to show that the convergence of configuration interaction in spacetime has similar properties to its usual application in ground state chemistry,” he explains. “To do this, we had to find a system of interest where we could also control the importance of two-body and one-body interactions.” (Phys.org) —Amongst the late Richard Feynman’s many prolific and profound contributions to quantum mechanics, the eponymous Feynman clock is perhaps one of the more innovative. Conceived as a solution to the problem of quantum simulation, the Feynman clock proposes using quantum computers to simulate quantum systems – and in so doing, conjectures that if a quantum system moves stepwise forward and then backward in time in equal increments, it would necessarily return to its original state. While originally a linear concept, scientists at Harvard University and the University of Notre Dame recently generalized the proposition to construct a more flexible discrete-time variational principle that leads to a parallel-in-time algorithm. (A variational principle is a scientific principle, used within the calculus of variations, which develops general methods for finding functions which minimize or maximize the value of quantities that depend upon those functions.) The researchers then used that algorithm to describe time-based quantum system evolution as a ground state eigenvalue problem – that is, the quantum system’s lowest energy state – which led them to realize that the solution of the quantum dynamics problem could also be obtained by applying the traditional ground state variational principle.

One of the paper’s key findings was that the new construction performs favorably against existing algorithms. “We demonstrated that for a representative quantum system, when the same dynamics and partitioning is performed, our algorithm would finish in less human time than the competing algorithms by making use of parallel computer architectures,” McClean says. “We ensured that all factors in our comparison were as equal as possible, converging to the same level of accuracy and averaging the speedup results over different time partitions.”McClean acknowledges the possibility of constructing similar algorithms from the other time-dependent variational principles. “However,” he points out, “one must be careful when selecting spacetime basis functions. These methods are in their infancy, and it’s a current research topic to develop them for use with the Schrodinger equation and quantum mechanics.”In a similar vein, McClean states that there are other methods that use extended spacetime to remove time-dependence from a problem. “However,” he clarifies, “these methods use the time-independent Hamiltonian in a way that is similar to traditional time-stepping, retaining many of the drawbacks. In our approach, we take a time-independent construction whose ground state directly encodes the dynamics, allowing us to use any number of previously developed techniques for determining the ground state.”In addition, the metrics inspired by their approach can be used to quantitatively understand the errors resulting from truncating the Hilbert space of many-body quantum dynamics. “In order to make quantum simulations tractable,” McClean explains, “it’s almost always necessary to hypothesize that a small part of the quantum space is relevant and simulate exclusively in that space. Our metrics allow researchers to quantitatively assess if the selected space includes all the interesting quantum dynamics – and if not, at exactly what time the violation occurs, thereby making it unnecessary to throw out their entire simulation.” For example, to simulate the dynamics of charge transfer in a protein, it would be necessary to pick a subset of quantum states and model the dynamics within them. “Our error metrics could allow someone to quickly discover if they had selected the wrong states, and reselect them before too much computational power had been wasted.”In other cases, he continues, the necessary states for simulation might be known, but the total time of simulation needed to see a rare event of interest might be too long for a single processor run in serial . “In that case, our technique could be used in conjunction with spatial parallelization to parallelize over time and reduce the human time required to see that rare event. This leads to faster results and more rapid development of continuing experiments.”Moving forward, McClean believes that there are many untapped resources in the field of quantum information which have the potential to advance classical simulation techniques. “Methods developed for adiabatic quantum computation may be directly applicable to our method to further refine its speed and accuracy. In terms of the planned next steps in their research, he adds that they are looking at applying more advanced techniques from electronic structure to the ground state formulation of dynamics. “Hopefully,” he adds, “the methods that have been successful in describing these problems can yield new insights into dynamics problems for quantum chemistry.”McClean notes that there are other areas of research that might benefit from their study. “Our method should be generally applicable across many computational domains that study the time dynamics of physical systems,” he tells Phys.org. “While many schemes currently exploit spatial parallelism to take advantage of modern supercomputers, temporal parallelism has been a relatively untapped resource to date. Our method and variations of it,” McClean concludes, “will likely be very useful in tapping this additional resource to scale physical simulations to previously unreachable timescales.” The spin triangle within the vanadium compound, used as a model system for the TEDVP.

Bat species found to have tongue pump to pull in nectar

first_img More information: Nectar uptake in bats using a pumping-tongue mechanism, Science Advances  25 Sep 2015: Vol. 1, no. 8, e1500525, DOI: 10.1126/sciadv.1500525AbstractMany insects use nectar as their principal diet and have mouthparts specialized in nectarivory, whereas most nectar-feeding vertebrates are opportunistic users of floral resources and only a few species show distinct morphological specializations. Specialized nectar-feeding bats extract nectar from flowers using elongated tongues that correspond to two vastly different morphologies: Most species have tongues with hair-like papillae, whereas one group has almost hairless tongues that show distinct lateral grooves. Recent molecular data indicate a convergent evolution of groove- and hair-tongued bat clades into the nectar-feeding niche. Using high-speed video recordings on experimental feeders, we show distinctly divergent nectar-feeding behavior in clades. Grooved tongues are held in contact with nectar for the entire duration of visit as nectar is pumped into the mouths of hovering bats, whereas hairy tongues are used in conventional sinusoidal lapping movements. Bats with grooved tongues use a specific fluid uptake mechanism not known from any other mammal. Nectar rises in semiopen lateral grooves, probably driven by a combination of tongue deformation and capillary action. Extraction efficiency declined for both tongue types with a similar slope toward deeper nectar levels. Our results highlight a novel drinking mechanism in mammals and raise further questions on fluid mechanics and ecological niche partitioning. Scientists have seen many examples of animals that lap up liquid in many different ways, they have also seen examples of animals that are able to suck water right out of a river, but until now, there has never been a documented sighting of a an animal that is able to pull a liquid against gravity, using a pumping-mechanism.Intrigued as to how Costa Rican Orange Nectar Bats pull nectar from plants, the team set up a high-speed video camera next to a test tube with a clear liquid meant to serve as nectar and recorded several of them in action. In studying the video, the researchers discovered that the bat lowered its tongue into the liquid and then simply held it there while the liquid miraculously made its way up the tongue and into the mouth. Closer examination showed that the tongue had two grooves (which were open to the air) along its length and that tiny muscles appeared to be undulating along the sides of the groves as the liquid was pulled up—serving as a pumping mechanism of some sort. Explore further Hummingbird tongues are tiny pumps that spring open to draw in nectar (Phys.org)—A trio of researchers affiliated with the University of Ulm in Germany and the Smithsonian Tropical Research Institute in Panama has found that one species of bat has a method of collecting nectar that has never been seen before in any other animal. In their paper published in the journal Science Advances, the team describes how they discovered the unique eating method using high speed cameras, and their theories on how it works.

They believe it is likely the liquid is held in the grooves by capillary action, and that the tiny muscles somehow force the liquid to move upwards, against gravity—sort of like allowing one end of a sponge to rest in water while continuously wringing out the water that is pulled into other parts. The result is an odd, unique and efficient means for drawing nectar from a flower. They note that the unique physiology of the mouth suggests that the bats evolved their way of eating independently of other species.

Credit: Zinger et al. ©2018 American Chemical Society Nanotechnology could redefine oral surgery Journal information: ACS Nano © 2018 Phys.orgcenter_img More information: Assaf Zinger et al. “Proteolytic Nanoparticles Replace a Surgical Blade by Controllably Remodeling the Oral Connective Tissue.” ACS Nano. DOI: 10.1021/acsnano.7b07983 Currently, more than 80 nanotechnologies have been approved for a variety of medical applications, from treating cancer to bioimaging to tissue remodeling. Now in a new study, researchers have shown that enzyme-containing nanoparticles can perform minor dental surgery and improve the outcome of dental braces for reorienting severely misaligned teeth into their proper position. Tests showed that rats treated with the nanoparticles before wearing braces exhibited better tooth alignment, reduced tooth relapse, faster recovery, and less pain compared to rats that underwent traditional surgery before braces.The researchers, led by Avi Schroeder at Technion-Israel Institue of Technology, have published a paper on the new nanotechnology in a recent issue of ACS Nano.”I think we are trying to change a 5000-year dogma of the way surgeries are performed,” Schroeder told Phys.org. “Specifically, the existing scalpel cannot distinguish between healthy and diseased tissue. However, enzymes can. Proteolytic enzymes are tuned to degrade specific tissues, without harming other healthy tissues. We believe that in the future surgeries must be more accurate, with less damage to healthy tissues.”The researchers designed the new procedure specifically to address cases of severe misalignment of teeth, termed “malocclusion.” Currently, this condition is treated with minor yet often painful surgery to cut the collagen fibers that connect the teeth to the bone, followed by braces to move the teeth into their proper position. Besides a painful recovery period, about 40% of patients experience relapse and require a second cycle of treatment.The nanotechnology treatment has the potential to greatly improve this treatment procedure by allowing the body’s own natural enzymes to break down the collagen fibers and for other natural biomolecules to rebuild the fibers when the teeth are correctly aligned with braces. To do this, the researchers engineered nanoparticles consisting of a liposome vesicle (basically an empty cell membrane) filled with the enzyme collagenase. Collagenase causes collagen fibers to weaken and break, but only when first activated by calcium, which occurs naturally in the mouth. In order to ensure that the collagenase only begins working at the surgical site, the liposome acts as a protective vehicle to safely transport the collagenase to the sulcus (located between the gums and teeth), where it begins diffusing out and interacting with calcium. The researchers determined the particular collagenase concentration that causes the collagenase to weaken the collagen fibers by approximately 50%, making it much easier for braces to reorient the teeth. Over the next several hours, the body’s own fibroblasts sense the weakened collagen and initiate collagen remodeling, restoring the fibers to their original strength. Overall, tests with rats showed that those treated with the nanosurgical procedure experienced a three-fold enhancement in tooth alignment, along with significantly less tooth relapse and less pain compared to rats treated with traditional surgery. The researchers attribute the improvement to the fact that the nanosurgical procedure allows the tissue and bone to be remodeled at the new orientation, in contrast to stressed teeth returning to their original position as often occurs in the traditional procedure. The results suggest that the nanosurgical procedure has the potential to replace the more invasive traditional method with an overall improved outcome.”Here we demonstrated the bio-surgery approach for the first time,” Schroeder said. “We plan to expand to other organs and more challenging procedures in the future.” This document is subject to copyright.

Chimp communication gestures found to follow human linguistics rules

first_imgCredit: CC0 Public Domain A team of researchers with members from the U.K., Switzerland and Spain has found that chimpanzees use communication gestures in ways that follow human linguistic rules. In their paper published in Proceedings of the Royal Society B, the group describes their study of chimps communicating with one another in the wild, and compares their observations against human communication rules. Explore further Journal information: Proceedings of the Royal Society B Over the years, linguistic researchers have discovered that human language conforms to specific rules regardless of the language in which it is spoken. Such rules have names to make them more easily discussed. One such rule, Zipf’s law of abbreviation, holds that words that are used frequently tend to be short. Another rule is called Menzerath’s law—it says that large language structures tend to be made up of multiple short segments (syllables) when spoken. In this new effort, the researchers wondered if such rules might apply to other animals. To find out, they obtained and studied video footage of wild chimpanzees living and communicating in Uganda’s Budongo Forest Reserve.The researchers were able to identify approximately 2,000 examples of 58 unique gestures used by the chimps when communicating with one another. Since chimps cannot speak, they communicate by using hand gestures, body posture, facial expressions and they make various noises. By combining gestures that are available to them, chimps are able to convey a wide variety of messages to one another.The researchers found that human language rules do apply to the chimpanzees’ use of gestures—the most commonly used gestures tended to be quite short, for example, and longer gestures tended to be broken up by multiple shorter gestures. They suggest that this indicates that despite the major differences in the mode of communication, the underpinnings of the two communications systems follow the same basic mathematical principles. Interestingly, an international team of researchers found just last year that human toddlers and chimps have very similar communications systems.The researchers plan to continue their research by expanding their analysis to include other species—they expect to focus on bonobos next because they are known to use many of the same gestures as chimpanzees.

At the very onset the cafe soothes you with the lovely blue interiors. Since the focus is on Mediterranean cuisine, the setting is perfect.   While you have to forget about the liquor for a while, the Cafe whips up some great mocktails. Over-looking a park, it is a great place to spend a nice lazy afternoon over the dip platter. We tried the nachos topped with cheese and beans and they were very good.  For the main course we were served the Turkish Turlu (Pan Roasted Veggies – Chickpeas – Herb Couscous – Tomato Celery Broth) and the Grilled Fish (Grilled fillets of fish – Sautéed Veggies – Herbed potatoes  – Lime Coriander Cream Sauce). The Grilled Fish is excellent and definitely something we would recommend to anyone visiting the cafe. The desserts are excellent at Market Cafe – try the molten chocolate for sure. It is divine and so excellently sinful that it is a must for the winter chill. A meal for two comes to about Rs 1500 (without taxes). Do head over – this place is worth a visit.last_img read more

Bengali film on treasure hunt to be released soon

first_imgKolkata: Byomkesh-actor Abir Chatterjee will now don the hat of a treasure hunter in ‘Guptodhoner Sondhane’, which is claimed to be the first big Bengali film on treasure hunt, will be released this month. Eminent Bengali directors Goutam Ghosh, Kamaleswar Mukherjee and Arindam Sil are part of the team as the director Dhrubo Banerjee said they were here to enhance the quality of the film.Popular Bengali hero Abir Chatterjee said neither Sil, nor Ghosh nor Mukherjee carried the baggage of a film maker during the film’s shoot but did not divulge how their role unfolded in the film. Also Read – Heavy rain hits traffic, flights”All the three portray very interesting and important characters but how that will be a surprise. All I can say they brought more layers to the film,” the director said.Chatterjee, who had also portrayed the character of iconic Bengali sleuth ‘Byomkesh Bakshi’ in a string of Bengali films, said, “Bengalis are losing the spirit of going on exploration for treasure hunt. The film aims at fostering that spirit of adventures in every Bengali. To my knowledge it is the first big Bengali production on embarking on adventure for hidden treasure.” Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedChatterjee had been cast as Byomkesh in several films including Byomkesh Pawrbo, Har Har Byomkesh, Byomkesh Phire Elo, Badshahi Angti (featuring iconic sleuth Feluda) among others.Asked if his image as Byomkesh or Feluda will not come in the way of establishing the new role of a treasure-hunter history professor, visiting the country after seven years, Chatterjee said, “We are actors first and portray the role as demanded by the script. The audience is mature enough.” He said the film had references to the history of Bengal.”Instead of past instances of films based on literary works, here the films will be followed by novels in print and graphic novels. We intend to start a franchise,” he said.About casting Chatterjee in the lead role, he said, “I did not seek to find similarities between his portrayal as Feluda or Byomkesh. But I liked his smart and intelligent look which can be moulded in a different way than the previous characters.”Sonada aka Subarno Sen, the protagonist in his film, may give a break from the monotony of iconic characters of Feluda and Byomkesh to the Bengali audience, he said.’Guptodhoner Sondhane’ is the first instalment of a brand new franchise being introduced by SVF, Srikant Mohta said on behalf of the producers.last_img read more

Fire dept to soon introduce four robots in its fleet

first_imgKolkata: The state Fire and Emergency Services department will soon introduce four robots in its fleet for more effective firefighting in the city. The department has already got the necessary nod from the state Finance department for procuring the robots.”Our firemen face a lot of difficulties in dousing fire, particularly in chemical factories. In a number of cases there have been injuries to firemen during such firefighting operations. We will be soon floating an e-tender for procuring the robots. The robots can be used in highrise fires and in chemical fires,” said state Fire and Emergency Services minister Sujit Bose. Also Read – Bose & Gandhi: More similar than apart, says Sugata BoseThe department, which is taking a slew of measures for modernisation, is also introducing fire balls. “The balls will be used to extinguish fire in very narrow and congested places or in locked buildings where physical entry is extremely difficult.

A senior official of the department said that such fire balls are used for firefighting in a number of foreign countries and also in some other states in the country, particularly to extinguish fire in locked buildings.

The fire ball, which is smaller in size than a basketball but larger than a cricket ball, contains ammonium phosphate and ammonium sulphate. However, the balls don’t explode if they accidentally drop on the ground. It will burst only when it is thrown into a fire. The official said that allocation for procurement of modern equipments like robots or fire balls is expected to be made in the state Budget. The plans for procurement of the same have been discussed time and again in a series of meetings that followed after the fire at Bagree Market in September and the recent fire at Traders Assembly building in Gariahat in December. The firefighters had faced a daunting task in extinguishing the fire on both occasions. The department has also made plans to give basic training in firefighting to students of city schools and various clubs in the city.last_img read more

The First Recorded Labor Strike in History

first_imgWorkers strikes are a common way to push employers to pay a fair wage with fair benefits. When workers stop working, everything grinds to a halt. The use of strikes has been around since 1159 BC when the workers of Egypt’s King Ramses III, who were not being paid as promised, sat down and refused to work.According to reshafim.org, a papyrus written by the Egyptian scribe Amennakht at Deir el Medina records the strike on an almost day to day basis.Ramses III offering incense, wall painting in KV11.Ramses III inherited the title of Pharaoh about 1186 BC and began the 20th Dynasty in the New Kingdom, which lasted from about 1570 to 1069 BC.He reigned over a relatively peaceful Egypt for over twenty years until an invasion by the “Sea People” seriously depleted both funds and laborers who would normally have been working the fields to produce much needed food.The Sea People were a loose organization of mercenary and raiding types from the Mediterranean Sea area.This famous scene from the north wall of Medinet Habu is often used to illustrate the Egyptian campaign against the Sea Peoples in what has come to be known as the Battle of the Delta.No one knows what nationality they were, or if, in fact, several different nationalities were represented in these groups. Experts debate on the suggestions that they could have been Philistines, Italian, Mycenaean, Trojan, or Minoan, but nothing has been discovered to shed any light on this subject.Apparently, according to ancient.eu, the Sea People were so confident that they would subdue the Egyptians, they brought their families and household goods with them. Ramses knew the Sea People were powerful, as they had attacked Egypt several times before.A partial description of the hieroglyphic text at Medinet Habu on the right tower of Second Pylon (left), and an illustration of the prisoners depicted at the base of the Fortified East Gate (right), were first provided by Jean-François Champollion following his 1828–29 travels to Egypt and published posthumously.One of his strategies was to hide archers along the coastlines near the mouth of the Nile to prevent the boats from even entering the river. His tactics were a resounding success, and the prisoners taken were either forced into the Egyptian army or sold as slaves. Unfortunately, the war had proved to be extremely expensive.The next few years were peaceful, which allowed Ramses to begin work on many temples, and he and his entourage took a grand tour of Egypt, further depleting the coffers. Add that to increasing corruption in Ramses’ administration and you have a recipe for disaster.Relief from the sanctuary of the Temple of Khonsu at Karnak depicting Ramesses III. Photo by Asavaa CC BY-SA 3.0 – CopyThe first month in the 29th year of Ramses reign shows that the workers considered the elite of skilled craftsmen complained that their wages were eighteen days late. As a group they were met by the chief of police who agreed with their plight as they marched toward the Pharaoh’s palace.They were offered about half a sack of barley with which to make beer, but the workers were not placated. By the third month, they were threatening to rob the tombs for money for food.A carved relief from the Kadesh inscriptions showing Shasu spies being beaten by Egyptians.In the meantime, Ramses decided there would be a great celebration in honor of the 30th year of his reign. He and his advisors had no idea how to deal with the hungry workers as this sort of thing had never happened before. At one point, the officials gave the workers pastries reminiscent of Marie Antoinette’s “let them eat cake” remark. While the workers did take the pastries home to their families, they resumed their strike the next day.Sarcophagus of Ramesses III (Louvre).The pharaoh and his immediate court knew nothing of the strike, as the direct supervisors of the workers feared execution for not being able to control their men. Ramses’ jubilee was a great success with everyone dancing and drinking, but the strikes returned after the festival ended.The strikers were now disenchanted with the Pharaoh, who was supposed to be like a father to them, providing food and protection, and ensuring harmony in the people’s everyday lives.Amennakhte’s papyrus only goes to the year 29, first month of summer, day 16, and makes no mention of the results of the strike, but we should assume there was some sort of agreement made which enabled the monuments to be built and the people to be fed.Read another story from us:  Cheetahs were Domesticated as House Pets in Ancient EgyptThis was, however, the beginning of the decline of the Pharaoh’s power and his subject’s blind devotion.
