The BJP, a ruling coalition partner in Bihar, has accused the State administration of acting in a partisan manner in dealing with the communal clashes that broke out in several districts during the last week’s Ram Navmi celebrations. Recently, the State government had released funds for the repair of mosques, shops and madrassas damaged in the communal clashes — a move questioned by the State BJP leaders.A team of BJP leaders from the State met the police chief K.S. Dwivedi on Friday and submitted a memorandum asking why action was being taken only against members of the majority community for communal flare-ups alleging that members from both communities were involved and had suffered losses.The delegation demanded the “release of all innocent people and a high-level enquiry into the alleged partisan approach adopted by the police.”“This policy of appeasing one community has never paid off for the country,” said senior State BJP leader and former party MP C.P. Thakur. Communal incidents were witnessed in six districts in which several people were injured, shops gutted and mosques damaged. A total of 15 cases were registered by police and 214 people were arrested. The Opposition parties have charged Chief Minister Nitish Kumar of “surrendering before the aggressive BJP”.

Frustrated at the Mamata Banerjee government’s reluctance to accord Special Economic Zone (SEZ) status to its proposed software development centre in the state, Infosys has asked the goverment to either expedite it or return the ₹75 crore advance paid by the company for acquiring the land at Rajarghat.”We have told the state government that it should either give us the SEZ status or pay back the money which was advanced to get the land,” PTI quoted a senior Infosys official as saying. In 2008, the Bengaluru-based IT software services company had paid the money for a 50-acre plot at Rajarhat to build a development centre when the Left Front government was in power. The then government had agreed to give SEZ status to the first Infosys centre in the state, as it was estimated to generate 15,000 jobs.But it could not take off due to opposition from Mamata Banerjee’s Trinamool Congress, which came to power in 2011 and has remained firm in its decision.The Infosys official said that the new government cannot renege on a committment given by a previous government. “Even if governments change, the continuity in policies should not. We have immense faith in West Bengal”, he added.When asked if his company has decided to withdraw its project in West Bengal, he said, “We hope the government will change its mind.””What the state government would have to do is just forward our proposal to the Centre with a recommendation and nothing else. We have presence in 11 states across the country and all of them have done that,” Infosys spokesperson said.
Photo: Prothom AloIt is no other city than the capital of Bangladesh that has virtually come to a halt.Most of the roads in Dhaka city are unfit for commuting due to repair work, digging, new constructions, lack of coordination in development projects and finally the monsoons.Now, the helpless people of this mega-city spend hours on those roads, going to and from work.These sufferings have not been just for a week or a month, but have been carrying on for months on end.Yet, the city authorities or the government have taken no initiative to alleviate these woes. The people have apparently nothing to do. There is no solution to the problems in sight.The concerned authorities are offering no hope.”Weak management and meaningless random projects have brought the city to a standstill,” notes city researcher Nazrul Islam. He told Prothom Alo that the situation has become really bad.And now public health has been added to Dhaka’s problems. If things continue in such a manner, this, as apprehended, will soon become a ‘failed city’.A trip around Dhaka reveals most of the roads are in bad shape. These are being dug up, repaired, and there are ruts and potholes everywhere, with incessant rains making the situation worse. New roads are being constructed in both city corporation areas, footpaths are be demolished and rebuilt, drains are being laid down and there is water-logging all over. Normal commute is just impossible.Stepping out of the house, one is faced with dilapidated roads and chaotic traffic. It takes over two hours to travel a half-hour route.The city corporation, WASA and other authorities have pitched the people into this predicament. There is no one to help the people out of this rut.Sakib Hossain, resident of Bashabo, works for a research institute in Gulshan. On Tuesday, he left the house in the rain. When he reached Malibagh, he found the roads waist-deep in water. He told Prothom Alo, “I waited for inordinately long for a bus. When a bus finally came along, I had to push and scramble to get in. The driver told us to hold on tight because the road was in such a bad shape. This is a common situation during the rains.”At around 11 in the morning Tuesday, a little boy Rakib was going to Willes’ Little Flower School by rickshaw from RK Mission road, along with his father. On the way rickshaw hit a pothole and almost turned over. The father managed to grab his son and jump from the rickshaw. They were drenched in filthy water and the boy could not go to school.The people are now anxious about how to live through the rainy season. The heavy rains are predicted to continue for a couple of more days and it is still in the monsoon season, so the regular rains will not let up any time soon.The city people are worried.Architect Mobassher Hossain has said that the Dhaka residents are suffering due to the uncoordinated work of ignorant policymakers and inexperienced city managers. Speaking to Prothom Alo, he said, it is the responsibility of seven ministries and 54 organisations to ensure the development and civic facilities for the people of the city. There is no coordination among them. Some of them do not even want to coordinate. It is in their own interests to work separately.Photo: Prothom AloDhaka WASA consultant AKM Shahiduddin cited an example of this lack of coordination. He said the WASA had implemented a project to drain out water from Dhanmondi Road 27 and adjacent areas into Kalyanpur canal. But the city corporation made ‘surface drains’ there and ruined the entire project. As a result, Dhanmondi Road 27 and adjacent areas face water-logging whenever it rains, he added.Professor Nazrul Islam gives another example of the lack of coordination. He told Prothom Alo, mass transportation is a vital part of city management. Mass transportation is on the verge of collapse in the city. In this situation, the Dhaka city corporation (north) mayor took initiative for an integrated bus service. It was a good initiative, but this mass transportation is not for Dhaka north alone. It has to be linked with the south too. The government created the Dhaka Transport Coordination Authority few years ago, but what is its function? It has no visible work in the city so far.In 2009 the government approved a long-term plan and project funded by the World Bank, but lax implementation has rendered it one big loss. Had the government adhered to the project, the city would not have been in such a state at present. Now they will have to work as if on war footing.Dhaka north mayor Annisul Huq says, there has been a delay in the project to evict illegal occupants, and now the rains have started. “That is why the people are suffering. We are working as fast as we can to complete the on-going project and relieve the people of their sufferings,” he added.A Tk 600 crore (Tk 6 billion) project has been implemented this year in Dhaka north. And Tk 180 crore (Tk 1.8 billion) has been allocated for regular repairs of roads, drains and footpaths. Even so, the people suffering simply continue to escalate.* This column, originally published in Prothom Alo print edition, has been rewritten in English by Ayesha Kabir.
Space-Time is SpinorialSparling’s spinorial theory is based on Einstein’s general relativity and Elie Cartan’s triality concept, which can link space-time with two twistor spaces. Twistor spaces are mathematical spaces used to understand geometrical objects in space-time landscapes. Sparling explains spinors in the following way:“In physics, the idea of a spinor stems from the finding that spectral lines of atoms seem to behave as if the angular momentum of the particles radiating photons was in half-integral units of the quantized spin (whose size is determined by Planck’s constant). This was fully explained by Dirac’s famous theory of the electron, which led him to successfully predict the existence of the positron.” Some spinorial particles include the electron, muon, tau, proton, neutron, quarks, neutrinos, and all their anti-particles, which are called fermions and have half-integer spins. There are also non-spinorial particles, called bosons, such as the photon, graviton, pion, mesons, the W and Z bosons, the Higgs, (if it exists) and so on, which have an integer spin, Sparling explains. “The key difference between spinors and non-spinors is their behavior under rotations: typically, non-spinorial (integer-spin) particles return to their initial value under a 360-degree (or 2π-radian) rotation; however, the spinorial (half-integer-spin) fermions actually change sign under a 360-degree rotation, requiring a full 720-degree rotation to get back to their initial values. This is completely foreign to our naive idea of how rotations work, and yet it is a basic part of reality. “Consider this analogy: if you take a plate and hold it in one hand horizontally whilst twisting it under your arm backwards through 360 degrees, your arm ends up in the air after one rotation, and it needs another 360 degree rotation to get it back to the beginning,” he said. Twistors, then, are a special kind of spinor first introduced by Penrose (Sparling was a PhD student of Penrose). In Sparling’s theory, the two twistor spaces are each six-dimensional, forcing space-time to also have six dimensions, in accordance with Cartan’s unifying triality. Because the twistor spaces’ geometry is ultra-hyperbolic, the extra dimensions are time-like.“My work has three six-dimensional spaces which at one level are on an equal footing and which are bound together by a new transform, which I call the Xi-transform,” Sparling said. “Two of these spaces can be understood at the space-time level as twisters. Then the third space can be given a space-time interpretation, but only if we have two extra dimensions: so it is the requirement of symmetry between the spinor spaces and the space-time that dictates that the extra dimensions be there.”A Harmonious ConcinnityWhile the concepts of twistor theory and spinors have been previously investigated as an alternative to space-time, Sparling explains how his new proposal is slightly different because it’s not a complete replacement of space-time. Rather, the guiding principle of his idea is that of a harmonious combination of three entities, or a “trinity.” Each part of the theory reinforces the other parts. “If one accepts that there are these three spaces [space-time and two twistor spaces] that are central to my theory, one looks for a theory which unifies them; this would be the ‘concinnity’,” he explained. “An indicator that there might be such a theory comes from the theory of Jordan algebras, which naturally unifies the three spaces into a twenty-seven dimensional whole, called an exceptional Jordan algebra.” Sparling’s student Philip Tillman and ex-students Dana Mihai, Devendra Kapadia and Suresh Maran also played a significant role related to this work. “A second indicator is that there are two radically different descriptions of massless particles, such as the photon: the standard one uses Fourier analysis in space-time and another uses twistor theory and sheaf cohomology,” he added. “The mathematical formalisms used in these two different descriptions are so different that it is simply amazing that they are describing the same basic physics. The concinnity would provide an explanation for this. This would then unify twistor theory, space-time theory and string theory—this is very tentative, however.“A very interesting aspect is that Newton fought strongly against the idea of the trinity (in a religious context),” Sparling noted. “It is ironic that I am invoking that very same idea in the context of gravity: perhaps Newton saw that the concept could be used in physics, but because he could not think of such a use he rebelled strongly against it (of course, I have no evidence for this!).”Although the theory is not definitive, Sparling explains that several major ideas in current physics would likely play a role (such as condensed matter physics, category theory, non-commutative geometry, string theory, and the structure of superfluids). Such connections might also point the direction to a unified theory, though currently speculative.“My work can be seen as a strong antidote to the present air of pessimism surrounding modern fundamental physics,” Sparling said. “As is well-known, string theory has been roundly criticized for its lack of predictive power. String theorists have been reduced to an absurd reliance on the anthropic principle, for example. Here I have a clear-cut prediction, which goes against the common wisdom, which gives experimenters a target to go for: first find the extra dimensions, then decide their signature (a very tough homework assignment!). Of course I could be proved wrong, but the effort to decide is surely worthwhile.“Actually, in the area of philosophy, I am in opposition to string theory,” he said. “It is a top down theory: dream up something that works in some high dimension and then try to finagle some way of reducing to fit in with the lower-dimensional theory. My approach is bottom up: take the existing four-dimensional theory seriously and try to build up from it. This is very tough to do. Hopefully my ideas work. Note that my work only constitutes a possible beginning at a more inclusive theory.”Sparling continues to explore the ideas of this 6-D time-like spinorial theory of space-time, with support from a workshop at the BIRS Institute in Banff, Canada, and ideas from philosophers including Alexander Afriat, Steve Awodey, Jonathan Bain and Rita Marija Malikonyte-Mockus. He predicts that experimental investigations in the near future—such as the Large Hadron Collider—might uncover the extra dimensions. Citation: Sparling, George A.

Proposed Spacetime Structure Could Provide Hints for Quantum Gravity Theory The analytical structure underlying the spinorial theory can be represented visually. The structure is a Xi-transform, which moves between the three spaces in the directions given by the bendings of the upper case Greek letter Xi. The distorted squares represent the wave operator. The product of a wave operator and a Xi transform, taken in any order, is zero. Image credit: Erin Sparling. This document is subject to copyright.

Image credit: Erin Sparling Explore further Sparling’s paper, which was published in the Proceedings of the Royal Society A, lays the groundwork for his theory. He explains how spatial dimensions contain positive signs (e.g., Pythagoras’ 3D space is expressed as the sum of the squares of the intervals in three directions, x, y, and z). Minkowski’s time-like dimension, on the other hand, combines these three dimensions with the square of time displacement, which contains an overall negative sign. “In three dimensions, the formula reads s2 = x2 + y2 + z2,” Sparling explained to PhysOrg.com. “Our standard spacetime has four dimensions, but the formula has a critical minus sign: s2 = x2 + y2 + z2 – t2. The Lithuanian Hermann Minkowski invented this idea, which was published just six weeks before he died. Indeed, [Sir Roger] Penrose, for one, says that special relativity was not a finished theory until Minkowski’s famous Raum und Zeit [‘Space and Time’] paper.”Up until now, Sparling explains, most theories concerning extra dimensions have dealt with space-like rather than time-like dimensions, which results in a “hyperbolic” rather than an “ultra-hyperbolic” geometry. However, Sparling notes that there are no a priori arguments for a hyperbolic geometry, and he looks into the possibility of a “spinorial” theory of physics, where six dimensions of space-time arise naturally. “In general dimensions, we say that the space-time is hyperbolic if there is only one minus sign in the formula for s2,” he said. “So, for example, in the ten dimensions of superstring theory, there are nine spatial dimensions with plus signs and one minus sign. Only in that situation is there a clear-cut distinction between the future and the past.” “In my case, I am led to the conclusion that the ordinary four dimensional space-time extends naturally into six dimensions: the four dimensional space is hyperbolic as usual, but in the surrounding space there are equal numbers (3 each) of space and time dimensions, so the formula for s2 reads something like s2 = x2 + y2 + z2 – t2 – u2 – v2, where u and v represent the new time variables. I call this structure a (3, 3)-structure (mathematicians call it ultra-hyperbolic).” In a recent study, mathematician George Sparling of the University of Pittsburgh examines a fundamental question pondered since the time of Pythagoras, and still vexing scientists today: what is the nature of space and time? After analyzing different perspectives, Sparling offers an alternative idea: space-time may have six dimensions, with the extra two being time-like.
