Selfticking oscillator could be next for portable atomic clocks

first_img“Most conventional atomic clocks need a more conventional, non-atomic clock, like a quartz crystal, to keep them ticking,” William Happer tells PhysOrg.com. “We’ve developed a system that would be self-ticking, using a specific laser.” Redefining the limits of measurement accuracy This document is subject to copyright.

The atoms in the vapor cell notice if the frequency of the mode-locked laser drifts and they automatically correct the frequency with no need for any external feedback loops.”Happer continues: “An important benefit of push-pull pumping with alternating circular polarization is that none of the atoms are wasted.” “In most atomic clocks,” Jau adds, “many of the atoms are wasted. Only a very few are in the clock state. With this push-pull pumping, all of the atoms are put into a clock state.”Along the way, the two discovered something interesting. “The self-modulation occurs over a limited range of laser injection current. We weren’t surprised that too little current didn’t work. What surprised us was that too much current caused the laser to stop modulating,” Happer says. Jau continues: “This new oscillator, where the polarized atoms, the modulated photons, and the laser gain centers are all coupled together has very rich and interesting physics. ”Happer does point out that these oscillators could not replace the extremely precise, but large atomic clocks that occupy whole rooms. “It’s really to improve the workings of small, portable atomic clocks,” he emphasizes. “It eliminates the need for quartz crystals or photodetectors. Hopefully, with fewer parts, it will be less expensive to manufacture, and more stable.”Jau agrees: “This is a primitive idea, how to make an atomic clock by using pure optical methods without a quartz crystal. But it works better with reduced components and power consumption.”Copyright 2007 PhysOrg.com. All rights reserved.

He, along with his young colleague Yuan-Yu Jau, invented a push-pull laser-atomic oscillator that can be useful in a variety of applications, including questions of fundamental physics, use in portable atomic clocks and coherent optical combs. “We didn’t start out thinking about applications, really,” Happer says. “We’re physicists. We just wanted to see if we could make this type of oscillator work.” The results of Happer and Jau’s work can be found in Physical Review Letters: “Push-Pull Laser-Atomic Oscillator.”Jau explains that even though they didn’t set out to build a better portable atomic clock, he thinks that they have succeeded. “We believe this is the first demonstration of making an oscillator that produces an atomic-clock signal in both electrical and optical forms by purely optical means,” he says. “This is simple. There are fewer components and lower power consumption.”“The new clock needs neither a quartz crystal with its electronics nor a photodetector,” Happer adds.Jau and Happer explain that in conventional atomic clocks, a quartz crystal is used “as a flywheel to keep the clock ticking strongly, with the atoms as a weak controlling element.” They point out that if the quartz crystal fails, the clock will cease working. “These are the types of clocks used in GPS satellites and in cell-phone towers,” Happer says.Jau points out that better precision is becoming increasingly necessary: “Mini atomic clocks can be helpful. There are many systems now working faster and faster, and transmitting large quantities of data, especially in high-speed communications. A laser atomic clock like this would be less complicated than the conventional kind, with comparable precision.”The push-pull laser-atomic oscillator built by the two consists of a semiconductor laser with alkali-metal vapor (in this case Potassium) in the external cavity. A time independent current is used to pump the semiconductor laser. “The laser will automatically modulate its light and its electrical impedance at the clock frequency of the atoms,” Happer says. This in turn eliminates the need for an external modulator, like the quartz crystal, or for a photodetector. Explore furtherlast_img read more

MIT groups shape display steps to new realm in interaction future w

first_img TED SpaceTop presenter is redefining hands-on computing (w/ video) Citation: MIT group’s shape display steps to new realm in interaction future (w/ Video) (2013, November 14) retrieved 18 August 2019 from https://phys.org/news/2013-11-mit-group-realm-interaction-future.html Their paper, “inFORM: Dynamic Physical Affordances and Constraints through Shape and Object Actuation,” by Sean Follmer, Daniel Leithinger, Alex Olwal, Akimitsu Hogge and Hiroshi Ishii of the MIT Media Lab, explains the system in detail. They wrote that the system is a shape display that enables “dynamic affordances, constraints and actuation of passive objects. Shape displays allow for more general purpose shape change than many other actuated or shapechanging interfaces, and thus are ideal research platforms.”Shape displays still remain limited in scale and cost, they said, but “this work is an exploration of the interaction capabilities and is meant to inspire further research in this area. Our belief is that shape-changing interfaces will become increasingly available in the future, and this work tries to push towards creating a vocabulary and design space for more general-purpose interaction for shape displays, including rendering of both content and UI elements.”A key comment that indicates the role of inFORM within their overall research efforts is what they say on their inFORM web page: “InFORM is a step toward our vision of Radical Atoms.”The Tangible Media Group explain how they view graphical user interfaces, tangible user interfaces, and Radical Atoms: “A graphical user interface only lets us see information and interact with it indirectly, as if we were looking through the surface of the water to interact with the forms below.” A tangible user interface, meanwhile, is “like an iceberg: there is a portion of the digital that emerges beyond the surface of the water—into the physical realm—so that we may interact directly with it.” Radical Atoms describes the group’s “vision for the future of interaction, in which all digital information has physical manifestation so that we can interact directly with it—as if the iceberg had risen from the depths to reveal its sunken mass.” (Phys.org) —The Tangible Media Group at MIT Media Lab have been working on a shape-shifting surface called inFORM where, as their video indicates, users interact with digital matter in interesting ways that go far beyond boxed-in interactions with a traditional computer. Outside MIT, observers have described their system not only as a shape display but as a shape-shifting surface; The team at MIT that is behind inFORM explain it as a “Dynamic Shape Display that can render 3D content physically, so users can interact with digital information in a tangible way. inFORM can also interact with the physical world around it, for example moving objects on the table’s surface. Remote participants in a video conference can be displayed physically, allowing for a strong sense of presence and the ability to interact physically at a distance.” Explore further More information: tangible.media.mit.edu/project/inform/tangible.media.mit.edu/vision/ © 2013 Phys.org They are now exploring application areas for the inFORM shape display. How could it be used in real-life scenarios? The team sees one potential in geospatial data, such as maps, GIS, terrain models and architectural models. “Urban planners and architects can view 3-D designs physically and better understand, share and discuss their designs.” They would also like to explore surgical simulations.

Solar cells made from polar nanocrystal inks show promising early performance

first_img Explore further (Phys.org) —Achieving a balance between low-cost fabrication and high efficiency is key to the future success of solar cells. Over the past several years, researchers have been working on developing low-cost methods to manufacture solar cells. One of the most promising methods is solution processing. More information: Joel van Embden, et al. “Cu2ZnSnS4xSe4(1−x) Solar Cells from Polar Nanocrystal Inks.” Journal of the American Chemical Society. DOI: 10.1021/ja501218u Journal information: Journal of the American Chemical Society Citation: Solar cells made from polar nanocrystal inks show promising early performance (2014, April 15) retrieved 18 August 2019 from https://phys.org/news/2014-04-solar-cells-polar-nanocrystal-inks.html In a new paper, Dr. Joel van Embden, et al., from CSIRO Materials Science and Engineering, Australia, have used a low-cost solution processing method to fabricate nanocrystal-based solar cells made from environmentally benign polar nanocrystal inks. While previous solar cells made from nanocrystals have required the use of solvents that are highly toxic or contain high concentrations of organic contaminants, in the new study the researchers were able to use cheap, non-hazardous solvents instead, such as simple alcohols. Even at this early stage in their development, the solar cells exhibit efficiencies of up to 7.7% and appear to be promising candidates for future commercial applications.”The greatest significance of our work is that it proves the ability to take cheap materials and process them into efficient solar cells using scalable methods and environmentally friendly liquids,” van Embden told Phys.org.As the researchers explain in their paper, the eventual uptake of solution-processed solar cells by the renewable energy market hinges upon both the ability to synthesize the required semiconductor ‘ink’ dispersions using scalable, low-cost methods, as well as the processing of these inks into devices using simple, benign chemistry. The new nanocrystal-based solar cells tackle both these challenges. Furthermore, the light-absorbing layer of these cells is made of nanocrystals composed of the inexpensive, earth-abundant materials copper, zinc, tin and sulfur. The researchers made the “solar ink” by modifying the nanocrystal surface chemistry to impart a high polarity. This high polarity was achieved by sticking specialized organic molecules called ligands onto the nanocrystal surface. The nanocrystal inks were then deposited onto conductive glass substrates and treated with selenium vapor using a process called selenization. This process transforms the nanocrystalline film into a microcrystalline film, which greatly enhances the films response to light. However, the degree of grain growth induced by this selenization process is currently limited. The researchers expect that this limitation is the most significant challenge facing nanocrystal-based solar cells.The future direction of this research lies in pushing toward higher device efficiencies by tailoring the nanocrystal ink composition. The polar inks enable beneficial dopants and growth-promoting additives to be included. This development opens the door to complex ink formulations that are expected to be suitable for printing next-generation solar cells.”We are in the process of developing multi-component nanocrystal inks, which contain various additives, each with its own role to play in improving the final solar cell’s efficiency,” van Embden said.center_img Breakthrough advances nanomaterials for printable solar cells Fabrication of a CZTSSe solar cell using a scalable polar nanocrystal ink.

Climatic history study suggests preColumbian Mesoamerican societys demise was more complex than

first_img Journal information: Proceedings of the National Academy of Sciences (Phys.org)—A team of researchers with members from Mexico, the U.S. and Germany has found that the demise of the pre-Columbian Mesoamerican society centered around a city known as Cantona, was likely due to a combination of weather and politics. In their paper published in Proceedings of the National Academy of Sciences, the team describes their study where they compared lake sediments with archeological evidence to provide a clearer picture of life in the area back when the city was still active and what factors led to both its rise and fall. © 2015 Phys.org More information: Cultural implications of late Holocene climate change in the Cuenca Oriental, Mexico, Tripti Bhattacharya, PNAS, DOI: 10.1073/pnas.1405653112AbstractThere is currently no consensus on the importance of climate change in Mesoamerican prehistory. Some invoke drought as a causal factor in major cultural transitions, including the abandonment of many sites at 900 CE, while others conclude that cultural factors were more important. This lack of agreement reflects the fact that the history of climate change in many regions of Mesoamerica is poorly understood. We present paleolimnological evidence suggesting that climate change was important in the abandonment of Cantona between 900 CE and 1050 CE. At its peak, Cantona was one of the largest cities in pre-Columbian Mesoamerica, with a population of 90,000 inhabitants. The site is located in the Cuenca Oriental, a semiarid basin east of Mexico City. We developed a subcentennial reconstruction of regional climate from a nearby maar lake, Aljojuca. The modern climatology of the region suggests that sediments record changes in summer monsoonal precipitation. Elemental geochemistry (X-ray fluorescence) and δ18O from authigenic calcite indicate a centennial-scale arid interval between 500 CE and 1150 CE, overlaid on a long-term drying trend. Comparison of this record to Cantona’s chronology suggests that both the city’s peak population and its abandonment occurred during this arid period. The human response to climate change most likely resulted from the interplay of environmental and political factors. During earlier periods of Cantona’s history, increasing aridity and political unrest may have actually increased the city’s importance. However, by 1050 CE, this extended arid period, possibly combined with regional political change, contributed to the city’s abandonment.Press release Explore further Intensive agriculture may have exacerbated drought in ancient Maya city Cantona was one of the largest cities in pre-Columbian Mesoamerica, with a population of 90,000 inhabitants at its peak. Scientists believe climate change was part of the reason the city was eventually abandoned. The researchers note that little work has been done to gain an accurate portrayal of what the climate was like in Mesoamerica during the times when various early people lived there, creating civilizations that in many cases vanished leaving behind ruins for modern scientists to ponder. In the case of Cantona, a city whose remains now lie east of modern Mexico City, the assumption by many has been, as it has for other long gone societies in central and South America, that it died due to drought. In this new study, the researchers assumed there was likely more to the story and so sought to find out more about weather conditions during that time.They started by collecting and studying sediments in nearby Aljojuca lake, which provided an accurate picture of drought conditions, before, during and after the time of the people in the area, which is now known as Cuenca Oriental.Prior research has shown that Cantona was occupied from approximately 600 BCE to 1050 CE and that its population grew steadily over the course of its first six hundred years, then grew faster from 50 and 600 CE—but the team notes, the lake sediment suggests that during that time period, the area had entered a drying trend. More interesting perhaps, they found that the population in the city grew even faster from 600 – 900 CE, despite increasing aridity. After that, things changed, though it is not clear exactly why, the population dropped over the following century and a half and then the people disappeared altogether. The team notes that later development in the city showed increased fortifications, which could have either been to repel invading armies or to fend off migrants seeking refuge from a drier environment that left them with little ability to farm on their own. That would explain, the team notes, the continued increase in population during the initial phase of the drought trend.

Ship ballast dumps around Australia climbing increasing risk of invasive species getting

first_img © 2015 Phys.org When big ships unload their cargo, they are left mostly empty, which creates a weight distribution problem—to fix that problem, giant pumps are used to fill ballast tanks with water from the sea in which they reside. Unfortunately, those pumps also suck up local organisms, which then live in the ballast tanks for some period of time as the ship travels to a place to pick up cargo. Upon arrival, the water in the ballast tanks is pumped back into the sea in anticipation of new added cargo. But, as scientists, environmentalists, sports enthusiasts and others have found, that ballast water may contain an organism that is able to take up residence (dubbed an invasive species) in its new part of the world, and sometimes is able to dominate those already there, putting the legacy residents at risk. In this new effort, the researchers sought to put some metrics on the ballast tank dumping problem around the shores of their native Australia in an attempt to better understand the invasive species risk for the country. They gathered historical shipping data for the period 1999 to 2012, which included ballast filling and dumping information and data regarding organisms that are known to be able to survive living in ballast tanks.In analyzing their data using a computer model, they found that ballast dumping in Australian seaports more than doubled during the study period and that the majority of the increase was related to mining and forestry operations, which meant that the dumping increase was more often located in remote ports near mines, rather than in more established areas. They also found that a large percentage of ballast water was coming from the waters around Southeast Asia and China, which they suggest offers an opportunity for more research regarding which species from those areas might be in the ballast water being dumped in Australian ports and other places around the world. Explore further (Phys.org)—A small team of math and biological researchers with the University of Adelaide, has found that the amount of ballast water being dumped into the waters around Australia more than doubled over a thirteen year study period increasing the possibly of invasive species introduction. In their paper published in Royal Society Open Science, the team describes how they studied historic ballast data to create a model of ballast dumping, and discovered that most of the increase can be attributed to mining operations. More information: Temporal modelling of ballast water discharge and ship-mediated invasion risk to Australia, DOI: 10.1098/rsos.150039 AbstractBiological invasions have the potential to cause extensive ecological and economic damage. Maritime trade facilitates biological invasions by transferring species in ballast water, and on ships’ hulls. With volumes of maritime trade increasing globally, efforts to prevent these biological invasions are of significant importance. Both the International Maritime Organization and the Australian government have developed policy seeking to reduce the risk of these invasions. In this study, we constructed models for the transfer of ballast water into Australian waters, based on historic ballast survey data. We used these models to hindcast ballast water discharge over all vessels that arrived in Australian waters between 1999 and 2012. We used models for propagule survival to compare the risk of ballast-mediated propagule transport between ecoregions. We found that total annual ballast discharge volume into Australia more than doubled over the study period, with the vast majority of ballast water discharge and propagule pressure associated with bulk carrier traffic. As such, the ecoregions suffering the greatest risk are those associated with the export of mining commodities. As global marine trade continues to increase, effective monitoring and biosecurity policy will remain necessary to combat the risk of future marine invasion events.

Beauty is only skin deep

first_imgMonsoon is here with the heavy downpour and a host of problem for hair and skin. During this damp season people tend to ignore their skin without realizing that often, increase in the humidity causes more damage to the skin. Remember that skin cells turnover increases during summer leading to the pile up of dead skin by the time monsoon begins. After bearing extreme heat leading to tans and itchy skin during the sweaty and stinky summer days, the arrival of Monsoon gives a sigh of relief.   Also Read – ‘Playing Jojo was emotionally exhausting’Make sure to exfoliate the skin well during this season. For this we can use the light, oil-free moisturizer that has lactic or kojic acid. During monsoon the strange and sudden increase in humidity make the skin oily, dry and dehydrated. This happens due to change in the ph level of the skin which makes it unstable. Hence it is very essential to take care of our skins during this season to look fresh and beautiful.

The Woman who Fell in Love and Married a Ghost

first_imgAmethyst Realm, a 27-year-old spiritual counselor from Bristol, England has a curious love-life. Appearing on the popular daytime TV show This Morning, she described how she hopes to settle down and perhaps even have a baby someday — with a ghost. She “met” and fell in love with her current spirit partner on a visit to Australia, while out for a walk in the bush. “It’s the one,” insists Realm. Apparently the ghost hitched a ride back to England on the plane with her, and the couple plan to get married.She explained to the bemused hosts her plans to start a ghostly family: “I’ve been looking into phantom pregnancies and I believe that a phantom pregnancy is actually a real pregnancy but you have a phantom inside you rather than a real baby.”Realm wasn’t afraid of the spirit that haunted her bedroom.However, Realm told This Morning presenter Eamonn Holmes that she hopes to have a physical baby with her phantom husband.“Maybe this is like a really nice dream that you can go back into and opt into whenever you want,” suggests Holmes.This is apparently not her first “close encounter” with a spiritual being.It all began in 2005 while her flesh-and-blood fiancé was working away from home. Realm says that she started to feel the presence of a supernatural being in the spare bedroom. She was not afraid of it, quite the contrary — convinced that this spirit had the hots for her, one evening she decided to make the first move. Dressing up in sexy underwear, she sat and waited.Incubus, colored aquatint, 1870. The incubus is a mythological demon that seduces women in their sleep.Realm recalls in the interview that she felt it’s presence just as she was dropping off to sleep. She goes on to explain that what followed was the first of many sexual encounters with a spirit. It wasn’t long before Realm’s fiancé moved out on the grounds that she was having an affair. He had seen the shadowy figure of a man through the bedroom window, reports Amethyst — much to her annoyance as she herself has never seen her lover in physical form.The relationship lasted for 3 years before Amethyst and her spirit-lover drifted apart.But for Amethyst, a relationship with a real man couldn’t compare to her spiritual experience and she turned to seeking love from ghosts. Amethyst claims to have had sexual encounters with at least 15 ghosts, including some one-night-stands.As This Morning presenter Phillip Schofield quipped, for Amethyst it was a case of “Once you go ghost, you can never go back.”Amethyst Realm is making plans to marry a Poltergeist.Realm explains that sex with a spirit is on a different level: “Ghost lovers tend to be more sensual and adept than the average bloke. There’s always more of a connection, because the sex goes beyond physical. It’s like any other kind of sex. The main difference is I just can’t see them.”Hers is not a unique case. Spectrophilia is the term used for a phenomenon of having alleged sexual encounters with ghosts, as well as being sexually aroused by images in mirrors. This occurrence has featured in folklore and myths from many different cultures including Arabic, Celtic, Greek and Hindu.Apulian red-figure bell krater depicting the ghost of Clytemnestra waking the Erinyes, c. 380-370 BC.Amethyst says that she immediately felt a strong connection when she first encountered her current lover, unlike anything she felt in any of her previous encounters.She gave in to the moment and did not think that it would develop any further as, according to Amethyst, “spirits tend to be quite static.” However, something extraordinary happened. During the flight home, she felt she was not alone, her lover was right beside her.It seems that her friends and family are quite accepting of the unorthodox relationship. Amethyst told People magazine that “Most of my friends are happy that I’ve found love. If they think I’m mad, they seem to be keeping it to themselves.”Nine months into their relationship, while the couple were hiking at Wookey Hole caves, her spirit asked her to marry him. This is the first time she had heard his voice. She shared for The Sun: “There was no going down on one knee — he doesn’t have knees. But for the first time, I heard him speak. I could actually hear his voice and it was beautiful. Deep, sexy and real.”Amethyst is making plans for a Pagan “handfasting” marriage ceremony. They are now choosing a ring that will symbolically be set with an amethyst stone.Read another story from us: The Mysteries and Ghosts Surrounding Ireland’s Most Haunted CastleAmethyst is not alone in making headlines for planning a ghostly wedding. Former Captain Jack Sparrow impersonator Amanda Teague from Northern Ireland reportedly married the ghost of a 17th century Haitian pirate, in 2016. She went public with her story at the beginning of 2018 so that people such as herself would not feel alone in pursuing love affairs with spiritual beings.However, because of the lack of documentation, such as the groom’s birth certificate, and the location (somewhere in the Irish sea) of the ceremony, this cannot be a legally recognized marriage. Too bad.last_img read more

Tudor Love Nest of Henry VIII and Anne Boleyn up for Sale

first_imgThere was a stretch of time when Henry VIII was madly in love with Anne Boleyn, the woman he made his second wife. In the year before the king married Anne, they were together much of the time, and one of their “love nests” is now up for sale for $3 million (£2.5 million). Shurland Hall, a 16th century Grade II listed house, was owned by one of the king’s courtiers, Thomas Cheyne, and he hosted Henry VIII and Anne Boleyn at his home for three days in the autumn of 1532.Afterward, the royal party left for France, where they met with Francis I in Calais.Shurland Hall. Photo by Maratho CC By 2.0On the Isle of Sheppey in Kent, southeast England, Shurland Hall currently has almost 10,000 square feet of living space and the medieval gatehouse offers three bathrooms, four reception rooms, a converted barn with kitchen, WC, and bar.Its distinctive octagonal towers and battlements resemble the Tudor Palace gatehouse at Hampton Court.According to the Daily Mail, “Wrought iron entrance gates hung upon stone pillars give way to a sweeping tree lined driveway, passing a beautiful boating lake en-route to a parking area.”Shurland Hall, front. Photo by John Vigar CC BY 2.0The house was built on the site of a 13th century castle owned by the de Shurland family. In fact, Sir Robert de Shurland is featured in the Ingoldsby legend of Grey Dolphin.Long after the Tudors, it was requisitioned during the Second World War. Following that, it fell into ruin, and was only saved by the Spitalfields Trust in 2006 with a grant from English Heritage and a loan from the Architectural Heritage Fund, according to Kent Online.It is currently home to retired advertising executive Dan Donoghue and his wife Suzanne who run a champagne importing business called Andromeda Boru.

Oil and tempera on oak, Thyssen-Bornemisza Museum, Madrid.While the house is being billed as a place where Henry VIII “courted” Anne Boleyn, the courting was well established by the autumn of 1532, with the two of them most likely secretly engaged.When Henry VIII began his famous pursuit of Anne Boleyn is unknown, but historians’ best estimate is 1526. Henry VIII had been married to Catherine of Aragon, a Spanish princess previously married to his older brother Arthur, since 1509.An early-20th century painting of Anne Boleyn, depicting her deer hunting with the king.He had taken mistresses before, including Anne’s sister, Mary Boleyn, but decided that he wanted to marry Anne, who was described as “rather tall of stature, with black hair and an oval face of sallow complexion… She was handsome to look at, with a pretty mouth.”Portrait of Anne BoleynIn 1527 King Henry told Catherine, his wife of many years, that he wanted an annulment. She refused to cooperate in any way, and her nephew, Charles V, the Holy Roman Emperor, supported her in her efforts to retain her rights as queen. The pope, under pressure from Charles V, would not grant Henry VIII his annulment, leading him to break with the Catholic Church.Related Video: A Stunning Look at Beautiful Highcliffe Castle in the UKBy 1532, Henry was moving toward making himself head of the Church of England, which Anne Boleyn, a religious reformer, supported.The driveway to Shurland Hall.Anne is supposed to have refused to sleep with the king until they were married, but it’s believed that they began to share a bed during the trip to Calais.

They married in secret in early 1532 and the future Elizabeth I was born on September 7, 1533.Less than three years later, Anne Boleyn was dead, executed for treason and adultery.Thomas Cheyne began his service to the royals with Henry VII and amazingly he served every Tudor monarch. He was knighted in 1513 and was a favorite of Anne Boleyn, who fought Cardinal Wolsey for his promotion in 1528 and 1529.

The Wacky Friendship Between Mark Twain and Nikola Tesla

first_imgIt’s often said that great minds think alike. That aphorism was definitely true of two icons of the late 19th and early 20th centuries, Nikola Tesla and Samuel Clemens. Tesla was a scientist whose work largely revolved around electricity; at that time, making your living as a scientist and inventor could often mean having to be somewhat of a showman.Clemens, in addition to being a writer, was fascinated with technology and science. Given not only the sharpness and clarity of their minds, but also the overlap in their interests, it seems almost inevitable that they would eventually cross paths with each other.Mark Twain in 1867.According to the science blog It’s Okay to be Smart, Tesla had a bout of severe illness in the 1870s before his emigration to the U.S. His condition was serious enough that his doctors thought he might not survive.Nikola Tesla aged 23, c. 1879.Since there was relatively little else he could do during that period of time, he read all the books he could from the local library. Among those books were several volumes of Twain’s earlier works, which Tesla described as “so captivating as to make me utterly forget my hopeless state.” He went on to say that those books may have been the reason for his recovery.It would be 25 years before the men met, but meet they did — and when Tesla told Twain about his illness and the role Twain’s writing played in his recovery, Twain was moved to tears.Mark Twain in the lab of Nikola Tesla, spring of 1894. Twain is holding Tesla’s experimental vacuum lamp, which is powered by a loop of wire which is receiving electromagnetic energy from a Tesla coil (not visible). Tesla’s face is visible in the background.The Irish Times reports that the writer and the inventor became friends in the 1890s. Tesla was living in New York, and even though Twain and his family lived in Europe at the time, Twain was a frequent traveler to New York.Twain became interested in Tesla and his work after hearing about an electric motor the scientist had invented while working for Westinghouse.Mark Twain, 1907.He recognized that Tesla’s motor was a better than a model his partner, James Paige, had come up with, which Twain had been thinking about investing in.Tesla advised against Paige’s motor, but Twain still invested in another of Paige’s machines – a mechanical typesetter – and took significant losses.A photograph of Nikola Tesla (1856-1943) at age 40.Twain was fascinated with electricity, and Tesla was looking for all sorts of new ways to use it, so it’s hardly surprising that Twain became a regular visitor to Tesla’s lab. There are a number of photographs from that period that were taken of Twain in the lab.One of the most famous, if not infamous, stories about Twain’s interactions with the devices in Tesla’s lab is this: Tesla had been working on a mechanical oscillating machine. It was like an engine that would put out an alternating current of high frequency. It also vibrated significantly.Serbian-American inventor and engineer Nikola Tesla (1856 – 1943, blurred at centre) performs an electrical experiment for writer Samuel Clemens, aka Mark Twain (1835 – 1910, left) and actor Joseph Jefferson (1829 – 1905), 1894. Photo by Kostich/FPG/Archive Photos/Getty ImagesTesla was curious about whether the vibrations might have some sort of beneficial therapeutic effect, and once, when Twain was visiting, he asked if he could try the oscillator out. Some sources suggest that Tesla knew Twain was prone to digestive issues and proposed the experiment as a way to cure his friend.Twain got on the oscillator, and the machine was started up. He reportedly enjoyed the effects, saying that it left him feeling invigorated and full of vitality.A multiple exposure picture of Tesla sitting next to his “magnifying transmitter” generating millions of volts. The 7-metre (23 ft) long arcs were not part of the normal operation, but only produced for effect by rapidly cycling the power switch.Despite Tesla’s repeated suggestions, the author refused to get off the machine as he was enjoying the feeling — that is, until he had to make a mad dash for the bathroom. Apparently, Tesla’s oscillating machine also worked well as a laxative.Twain would visit Tesla’s lab for years, and the men’s lively minds made for good company. They tried new experiments and also played some. At one time, Tesla shot an x-ray gun at Twain’s head.It’s possible that Tesla inspired Twain’s creation of Hank Morgan, the hapless visitor to the past in A Connecticut Yankee in King Arthur’s Court.Read another story from us: The Bizarre Obsessive Compulsive Rituals and Habits of Nikola TeslaAlthough there’s little remaining correspondence between the two great men, it is known that Tesla was invited to Twain’s daughter’s wedding, which is a sure sign of the real esteem that existed between them, and continued until Twain’s death on April 21, 1910.last_img read more

Colin McGregorMayweather press conferences will be better than the fight Video

first_imgFloyd Mayweather and Conor McGregor have offically confirmed their highly anticipated boxing match that has been rumored for the better part of a year. The fight will almost surely shatter all existing pay-per-view records and make both fighters a ton of cash, but will the actual fight be any good?Colin doesn’t think so, primarily because in order to make it happen, McGregor had to surrender any tactical advantage he might have by agreeing to a straight boxing match. He agreed to these concessions because he’s getting a massive stack of cash. You can’t blame him.It’s like Steph Curry agreeing to a Slam Dunk contest against LeBron James. Both are big names, but you don’t need a crystal ball to predict how it would end. The same applies to McGregor and Mayweather in a boxing match. If you’re essentially agreeing to get embarrassed, you should it least get paid.Vegas is giving McGregor a 14% chance to win the fight. Colin thinks that’s charitable. Enjoy the press conferences leading up to the fight because they’ll be better than the fight itself.“It’s a sanctioned payday. It’s Evel Knieval with no chance of crashing.”last_img read more
