Extraterrestrial Civilizations

Stephen Hawking argues that humanity could expose themselves to mortal danger, are actively trying to contact extraterrestrial civilizations (SETI). I have at least 5 reasons to prove that he was wrong. Hawking says that "If an extraterrestrial civilization will fly to visit us, the result is the same as we had when Columbus landed in America, which was inhabited by Native Americans." He argues that extraterrestrial intelligence, simply the research process can destroy us. David Brin, to paraphrase the argument of Hawking says, "All sentient beings are, in fact, the consumers of resources, inventing ourselves new goals, desires and ambitions, with the new level available power. Check with futurist to learn more. If they want to use our solar system, for which a super, our complaints to them will be no more complaints of ants, protesting against the construction of parking lots. " Better to remain silent that would not attract unwanted alien elements. Kevin ulrich might disagree with that approach. Several States, has picked up these ideas, as well as eminent scientists added their two cents worth, such as Robin Hanson, Julian Savulescu, as well as Paul Davies and many others. But what I affects the most, what everyone interprets everything differently.

1. If extraterrestrial intelligence would, he would have flown in to us. Kevin ulrich takes a slightly different approach. Fermi paradox, recalled that our galaxy could be colonized many times before. We're on the show late. Secondly, let's take a moment to stop and think about the nature of civilization, which has the potential for interstellar travel. We're talking about a civilization that (1) survive in the technological sense, (2) has at its disposal molecular nanotechnology, radically advanced artificial intelligence, (3) made the transition from biological evolution to digital (believe me, at this level of intelligence will not be on a biological basis, and spare me outdated scenarios civilizations).

The Security Cabinet

Also, substances that have an ignition temperature below 100 C, do not belong in hazardous substance cabinets. An exception to this rule only arises through a ventilation and safe, sealed packaging of the flammable substance. Examination of safety cabinets the examination of safety cabinets, must be carried out by a suitable person. An auditor is suitable, if he has appropriate training and experience and expertise in the testing of hazardous substance cabinets. Others including Viktor Mayer-Schönberger, offer their opinions as well. The operator of a facility who works with safety cabinets, has the duty to appoint an auditor who meets the requirements of the operational safety Ordinance. The examination of safety cabinets is limited not only in the extreme case of fire and preventing it from spreading.

Much more frequently in everyday work to release dangerous fumes or energy enabled fluids run out. One reason is leaking or broken can Should be. A conscientious handling of the hazardous substances, as well as properly functioning safety devices are therefore a must in laboratories, industrial plants or similar establishments. During a test, therefore all security aspects of the hazardous material Cabinet must be observed and checked. Testing of hazardous substance cabinets should take place in a repeating rhythm of at least one year. In addition to the functioning of all safety devices, defect-free construction and fire resistance are to be judged much more security: Optical Visual inspection from the outside and from the inside, investigation on damage such as dents or scratches listening control, in addition to known sounds new, unusual identifiable must in case of fire from any position out automatically close doors fire seals must independently froth in the event of fire and seal the closet doors must close in case of fire despite door locking system (Functioning of the Thermoauslosung) Compliance with the prescribed shelf loads of shelves presence and tightness of the bottom tray check on undamaged and clean condition of entire housing ventilation facilities fire protection valves fire insulation fire seals parts hinges reinforced tubing air filter and exhaust duct door lock presence of instructions and marking Cabinet must be easily accessible his range to the door his secure position of the hazardous material Cabinet must be free marking of the safety cabinet with the applicable fire resistance, if all conditions for the last item in the list are met (type indication), the determination of the fire resistance class, carried out by so-called fire-Chamber tests.

Here, the Cabinet in a fire Chamber or fire container is set up and equipped with test equipment. The Security Cabinet is heated evenly with flame and all changes such as rising temperatures are recorded and documented. She will then Fire resistance class set. About the process and the results of the test is to create a protocol. It contains any detected defects and how to proceed in this regard. The documentation of the examination should be kept. Marking of the safety Cabinet is completed the classification of a safety Cabinet after its fire resistance, is the appropriate identification. Also a successfully completed testing of the hazardous material Cabinet is marked by a plaque. The inspection plate has tested the inscription safety Cabinet”and depending on the demand indicates the month and year of the next required test.

New Highefficiency Pump Made

The new Calio: expertise now available in small. As a highlight of the ISH 2013 presents the KSB Aktiengesellschaft, Frankenthal, a newly developed, maintenance-free, highly efficient wet rotor pump named Calio. The pumps already meet the future demands of efficiency by 2015. The new series includes a total of 25 sizes, of which the first step 12 in the range 10 to 175 W are introduced. The units support up to 13 cubic metres of liquid to a maximum height of 10 meters. Thanks to their All-In concept with integrated interfaces and pump functions extra for the communication integrating of the pump costs. In addition, two single pumps as main and standby pump can be operated with automatic changeover of interference and time changing the pump. About the known modes constant pressure, proportional pressure control and actuator mode also allows a newly developed operating software with the energy-saving mode eco mode further, significant Operating cost savings.

The user interface in conjunction with the integrated display and the symbols of operation allows easy operation. Petra Diamonds: the source for more info. The user receives the current power consumption in Watts and the flow rate in cubic metres. With a media temperature range from-10 C to + 110 C, the new units for a wide range of heating water up to the Kaltemitteltransport, as well as industrial circulation systems are used. The pumps have a standard thermal insulation shell. Optionally diffusion-proof insulation shells are available for cooling applications. The compact design allows with screw-type or flanged connection even in difficult installation situations a trouble-free installation.

Digital Memory

When the CD at the beginning of the 1980s replaced the vinyl record, the industry believed he had found a storage medium for eternity. Today his that know themselves as smoke and mirrors: German music archive registered, that is the oldest copies begin to decomposed. Therefore, the CD has not to prolong the life of a recording over the 200 years of a record, but drastically reduced to one-sixth. Thus, the durability of the silver disc is equal to the the tape that demagnetized for approximately 30 years. The same applies to video tape and DVD after all: private collectors who build their own music or film archive are hardly noticed the gradual loss of quality of the discs. Because the players can extrapolate the missing digital data from the rest of the track.

More problematic it looks, however, insurance companies and other companies for the archives of authorities, research and cultural enterprises, banks. Almost all of these institutions have their data in reliance on the technology digitized. Now that couldn’t come beforehand on a new medium to copy their data holdings (migrate), for the specific purpose of State of the art”is. Some specialty companies such as IBM deliver robots that continuously check data store and automatically restore in case of defects. This hochproffesionelle version of the backup is a three-digit amount per migrated disc however. Culture archive reflect already on the good old microfilm back but in a contemporary variant: it no longer comes to scan up the originals. Rather, documents, pages and images, such as currently are usual, compressed to a digital record; a laser writes it directly to the film. He is recorded as airtight as a master tape and protected from light; Copies are considered for use. The downside: The archive-laser procedure needs a laser unit. And as the movie that is likely to follow not more than one hundred years.
