അന്യഗ്രഹജീവികളെ കണ്ടെത്താൻ സ്റ്റീഫൻ ഹോക്കിങ് അന്യഗ്രഹജീവികളെ തേടിയുള്ള മനുഷ്യന്റെ അന്വേഷണങ്ങൾക്ക് ഉണർവേകാൻ 10 കോടി ഡോളറിന്റെ വൻ ഗവേഷണ പദ്ധതിയുമായി വിഖ്യാത ശാസ്ത്രജ്ഞൻ സ്റ്റീഫൻ ഹോക്കിങ്. ലണ്ടൻ റോയൽ സൊസൈറ്റിയിൽ കഴിഞ്ഞദിവസം പ്രഖ്യാപിച്ച ‘ബ്രേക്ക് ത്രൂ ഇനിഷ്യേറ്റിവ്സ്’ പദ്ധതിക്ക് യുഎസ് ശതകോടീശ്വരൻ യൂറി മിൽനറാണ് ധനസഹായം നൽകുന്നത്. ഭൂമിയിൽ ജീവൻ സ്വാഭാവികമായി ഉടലെടുത്തതാണെങ്കിൽ, അനന്തമായ ഈ പ്രപഞ്ചത്തിലെ മറ്റിടങ്ങളിലും ജീവന്റെ സാധ്യത ഏറെയാണെന്ന് പദ്ധതി പ്രഖ്യാപിച്ചുകൊണ്ടു ഹോക്കിങ് പറഞ്ഞു. ഭൂമിയിലുള്ള നമ്മൾ ഏതെങ്കിലും അന്യഗ്രഹജിവികളുടെ നിരീക്ഷണത്തിലാകാനുള്ള സാധ്യതയും തള്ളിക്കളയേണ്ടതില്ലെന്ന് അദ്ദേഹം ചൂണ്ടിക്കാട്ടി. അന്യഗ്രഹജീവികളെ തേടിയുള്ള മുൻ ഗവേഷണ പദ്ധതികളെ അപേക്ഷിച്ച് കൂടുതൽ വ്യാപകമായ തിരച്ചിലിനാണ് പുതിയ പദ്ധതിയുടെ ശ്രമം. ഇപ്പോൾ നിരീക്ഷിക്കുന്ന പ്രപഞ്ചഭാഗങ്ങളുടെ പത്തിരിട്ടി കൂടുതൽ മേഖലകളിലേക്ക് നൂറിരട്ടി വേഗത്തിൽ തിരച്ചിൽ വ്യാപിപ്പിക്കും. ഭൂമിക്കു സമീപത്തുള്ളതും ക്ഷീരപഥത്തിന് അപ്പുറത്തുള്ളതുമായ പത്തുലക്ഷം നക്ഷത്രങ്ങളെ സൂക്ഷ്മമായി പഠിക്കും. റേഡിയോ തരംഗങ്ങ...

Indigenously Developed High Thrust Cryogenic Rocket Engine Successfully Ground Tested for a duration for 800 seconds India’s first indigenously designed and developed High Thrust cryogenic rocket engine generating a nominal thrust of 19 tonnes was successfully endurance hot tested for a duration of 800 seconds on July 16, 2015 at ISRO Propulsion Complex, Mahendragiri. This duration is approximately 25% more than the engine burn duration in flight. The engine will be used for powering the Cryogenic stage (C25), the upper stage of the next generation GSLV Mk-III launch vehicle of ISRO, capable of launching four tonne class satellites. This cryogenic engine of C25 Stage operates on Gas Generator Cycle using extremely low temperature propellants – Liquid Hydrogen (LH2) at 20 Kelvin (-253 deg C) and Liquid Oxygen (LOX) at 80K (-193 deg C). The various subsystems of the engine are – regeneratively cooled Thrust Chamber, Gas Generator, LOX and LH2 high speed turbopump sy...

What is Amateur Radio? When cell phones, regular phones, the internet and other systems are down or overloaded, Amateur Radio still gets the message through.   Radio amateurs, often called “hams,” enjoy radio technology as a hobby. But it's also a service –a vital service that has saved lives when regular communication systems failed. Who are Hams? Ham Radio operators are movie stars, missionaries, doctors, students, politicians, truck drivers and regular people. They are all ages, sexes and income levels linked by their interest in wireless communications technologies. There are more licensed American Amateur Radio operators now than ever before in history. Why do you need a license? While license application requirements vary by country, the Amateur Radio Service is also controlled by international law and agreements because radio waves do not stop for international borders. In its regulations ( Part 97 ), the Federal Communications Commis...

The Large Hadron Collider The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator . It first started up on 10 September 2008, and remains the latest addition to CERN’s accelerator complex . The LHC consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. Inside the accelerator, two high-energy particle beams travel at close to the speed of light before they are made to collide. The beams travel in opposite directions in separate beam pipes – two tubes kept at ultrahigh vacuum . They are guided around the accelerator ring by a strong magnetic field maintained by superconducting electromagnets . The electromagnets are built from coils of special electric cable that operates in a superconducting state, efficiently conducting electricity without resistance or loss of energy. This requires chill...

Sorry,  the LHC still hasn't sucked us into a black hole Apocalyptics sigh and hope something shows up The Large Hadron Collider (LHC) has still failed to produce microscopic black holes, according to a new analysis of data from the Compact Muon Solenoid (CMS) collaboration. The idea, beloved of theoretical physicists , lawyers , and cranks others , is that collisions even down to the Tera-electron-volt (TeV) scale could produce microscopic black holes. If they did pop up, it would be more than a curiosity: it would provide empirical support hitherto lacking for the notion that there are extra dimensions we haven't seen before. This, in turn, would give scientists a new angle for investigating the nature of gravity. In this paper at arX...
