New Triton submarine in race to reach ocean bottom

center_img © 2010 ( — Step back to 1960 when Trieste, the first and only manned vessel, reached the deepest known part of the ocean called Challenger Deep in the Mariana Trench near Guam. No other vessel has ever managed to reach this depth of near 36,000 feet. In an announcement this week, Triton Submarines hopes to be the next to reach this great depth in a newly designed submersible.

Physicist proposes simple experiment to detect foamlike structure of the universe

first_img Explore further More information: Is a tabletop search for Planck scale signals feasible, arXiv:1211.3816 [gr-qc] gravity theory is untested experimentally. Could it be tested with tabletop experiments? While the common feeling is pessimistic, a detailed inquiry shows it possible to sidestep the onerous requirement of localization of a probe on Planck length scale. I suggest a tabletop experiment which, given state of the art ultrahigh vacuum and cryogenic technology, could already be sensitive enough to detect Planck scale signals. The experiment combines a single photon’s degree of freedom with one of a macroscopic probe to test Wheeler’s conception of “spacetime foam”, the assertion that on length scales of the order Planck’s, spacetime is no longer a smooth manifold. The scheme makes few assumptions beyond energy and momentum conservations, and is not based on a specific quantum gravity scheme. Set up of suspended blocks showing (dotted) the alternative paths for the photon. E is the single-photon emitter, D and D’ are the single-photon detectors. BS denotes the beamsplitter and M the mirror. DL is the fi ber optics delay line, and EB are the electronics that trigger D and D’ through cable C. The optical elements to widen the beam before and focus it after each block are left out for clarity. In the real experiment the blocks would hang side by side.

Bekenstein, of the Hebrew University of Jerusalem, has proposed a simple experiment in a paper he’s uploaded to the preprint server arXiv, that he says could be used to measure quantum foam. Instead of looking to ever faster particle accelerators, he proposes using an ordinary block of glass, a laser and a detector.last_img read more

We invite family, friends, relatives, acquaintance, everyone! And then there is an inflow of gifts! Lots of them! Among the variety, there is one that stands common, Sweets! From kuch meetha ho jaye to ‘try this lovely shondesh’, we love sweets! We were a part of one such wedding like inaugural ceremony of a sweet shop, Kesar. Wondering how can Dilli walas celebrate without some glamour? It was Gauhar Khan who added the tadka. At the launch of Kesar, she cut a fabulous cake and congratulated the whole team of the Kesar’s for creating an unprecedented concept in India. In her address to the audience, Gauhar said, ‘I used to feel nostalgic about Dubai; my hometown, just for my cravings toward Arabic sweets and Turkish delights. With the launch of Kesar’s these nostalgic feelings come to an end and I am more than cherished to find these zero calories sweets here in Delhi’.Kesar’s sweets baskets comprises 250 varieties of designer sweets, 120 types of Arabic sweets, more than 50 types of Turkish delights and around 70 types of imported Swiss and Italian chocolates.

The trouble had brewed at Daribhit High School in Islampur over the recruitment of Urdu and Sanskrit teachers as the protesting students said they needed Science and English teachers instead. The students and the locals had stopped two newly-recruited teachers, one for Urdu and another for Sanskrit, from entering the school on September 20 resulting in a clash.

State OBC candidates not on Central NEET list Bengal govt urges Centre

first_imgKolkata: As many as 12,000 medical aspirants from Bengal on the state OBC list may not be able to appear for the National Eligibility cum Entrance Test (NEET) next year as their groups did not feature on the Central OBC list.Bengal government had taken up the issue with the Centre urging for the inclusion of OBC candidates from the state otherwise they would be deprived from various examinations including NEET. But no steps have been taken in this regard yet. Also Read – Rain batters Kolkata, cripples normal lifeMany of these candidates might have breathed a sigh of relief when the union Human Resource Development Ministry had assigned the National Testing Agency (NTA) to carry out NEET from the next year. Until the previous year, the Central Board of Secondary Education (CBSE) used to conduct the national level medical entrance examination. The responsibility of conducting the examination shifted after numerous errors were found in the vernacular question paper of NEET this year and there had been a protest by a large section of students from across the country. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedBut NTA might be taking the same footsteps as its predecessor did as it mentioned in the prospectus that the NTA authorities would not take any responsibility for the mistake(s) in regional language question papers and students have to do respective correction(s) in the examination hall according to the English version question(s). Following the issuance of the NTA prospectus, the doctors, students and their guardians have written to Prime Minister Narendra Modi and Union Health Minister JP Nadda seeking their intervention in this regard. Dr Amiya Kumar Maity, formerly attached to SSKM and Dr Priyanka Maity, an ex-medical officer of M R Bangur Hospital, who were among the doctors writing the letter to the PM, said NTA’s announcement admits that it does not have the mechanism to hold a multilingual exam like NEET. Dr Amiya Kumar Maity also said the OBC candidates from Bengal would have to appear for the examination as general category students as there is no specific column in the form for the OBC candidates. Many of these candidates who are above the age of 25 would not be allowed to sit in the exam. When Bengal government used to conduct medical entrance examination of the state, the OBC candidates up to the age of 30 were allowed to appear for the examination. The upward age limit for the general category student in the NEET has been fixed at 25. Apart from English and Hindi, NEET is conducted in 11 other vernacular languages including Bengali, Telegu, Assamese, Odiya etc. Around 75,000 candidates from Bengal are expected to take part in the NEET examination scheduled to take place on May 5 next year. On-line application has started from November 1 and would continue till November 30. “There is an obvious dichotomy as the State government certified OBC candidates, not on the Central list, have been given wrong information saying they are Unreserved or general category students. Instructions also say if they fill up the application form furnishing wrong information, criminal offences could be leveled against them and they would be barred from medical admission,” Dr Maity stated.last_img read more
