This meant waiting for half a year for the South Pole data, which could only be shipped out at the end of Antarctic winter. The sheer volume of data generated was also unprecedented – in one night the EHT generated enough data to fill half a tonne of hard drives. “We got super lucky, the weather was perfect,” said Ziri Younsi, a member of the EHT collaboration who is based at University College London. And, on one night in April 2017, everything came together. Observations at the different sites were coordinated using atomic clocks, called hydrogen masers, accurate to within one second every 100 million years. The success of the project hinged on clear skies on several continents simultaneously and exquisite coordination between the eight far-flung teams. “We hope to get that very soon,” said Doeleman. The collaboration is still working on producing an image of the Milky Way’s black hole. The second target, which yielded the image, was a supermassive black hole in the galaxy M87, into which the equivalent of 6bn suns of light and matter has disappeared. First was Sagittarius A*, the black hole at the centre of the Milky Way, which has a mass of about 4m suns. When observations were launched in 2017, the EHT had two primary targets. The EHT achieved the necessary firepower by combining data from eight of the world’s leading radio observatories, including the Atacama Large Millimetre Array (Alma) in Chile and the South Pole Telescope, creating an effective telescope the size of the Earth. This was once thought to be an insurmountable challenge. A lot of this material is destined for oblivion, although some of it is ejected as powerful jets of radiation.īut black holes are so small, dark and distant that observing them directly requires a telescope with a resolution equivalent to being able to see a bagel on the moon. This is the point at which escaping would require something to travel at faster than the speed of light – which as far as we know nothing does – so it is the point of no return.īlack holes are surrounded by an accretion disk of dust and gas, orbiting at close to the speed of light. The edge of the black hole is defined by its so-called event horizon. The equations predicted that, beyond a certain threshold, when too much matter or energy is concentrated in one place, space and time collapse, leaving behind a sinkhole through which light and matter can enter but not escape.Īt first these were thought to be mathematical oddities, rather than real astronomical objects, but in the past century overwhelming evidence has confirmed that black holes are out there. Medeiros said that the way in which PRIMO filled in that missing data was "a way that has never been done before by using machine learning.Black holes were first predicted by Einstein’s theory of general relativity, which reimagined gravity as the warping of space and time by matter and energy. "it provides a way to compensate for the missing information about the object being observed, which is required to generate the image that would have been seen using a single gigantic radio telescope the size of Earth," Lauer said. Doing that allowed the system to essentially fill in the blanks of what was missing in the 2019 image. ![]() In this case, they had computers look at more than 30,000 pictures of black holes taking in gas. Medeiros and others developed the PRIMO modeling system, which co-developer Tod Lauer says is a "new approach to a difficult task." That system used a type of machine learning that lets computers make rules based on large sets of "training material," AIS said. The width of the ring in the image is now smaller by about a factor of two, which will be a powerful constraint for our theoretical models and tests of gravity." ![]() "Since we cannot study black holes up-close, the detail of an image plays a critical role in our ability to understand its behavior. ![]() "With our new machine learning technique, PRIMO, we were able to achieve the maximum resolution of the current array," lead author of the research Lia Medeiros said in a press release.

![]() The specification for NLS_DATE_LANGUAGE is included because ' DEC' is not a valid value for MON in all locales. The date format in the example includes a two-digit number for the day of the month, an abbreviation of the month name, the last two digits of the year, and a 24-hour time designation. The default date format for an Oracle Database date value is derived from the NLS_DATE_FORMAT and NLS_DATE_LANGUAGE initialization parameters. The following is an example of an ANSI date literal:Īlternatively, you can specify an Oracle Database date value as shown in the following example: For each DATE value, Oracle Database stores the following information: century, year, month, date, hour, minute, and second.Ĭonverting a character or numeric value to a date value with the TO_DATE functionĪ date can be specified as an ANSI date literal or as an Oracle Database date value.Īn ANSI date literal contains no time portion and must be specified in exactly the following format: Although date and time information can be represented in both character and number data types, the DATE data type has special associated properties. The DATE data type stores date and time information. The following sections describe the datetime data types and interval data types in more detail: TIMESTAMP WITH LOCAL TIME ZONE does not store time zone information internally, but you can see local time zone information in SQL output if the TZH:TZM or TZR TZD format elements are specified.

However, there are some differences between LinkedIn profiles and resumes that you should keep in mind: Because they both show the background and qualifications of the same candidate, information about previous employment and experiences should be consistent between the two. You may be wondering how a LinkedIn profile is different from the traditional resume you are used to. What is the difference between a LinkedIn Profile and a Resume? LinkedIn also lets you stay in contact with people you meet at events or conferences and continue your correspondence.įor all of these reasons and more, LinkedIn is a professional networking platform you NEED to join. Here you can gain information, learn about job opportunities, and even participate in all kinds of discussions. LinkedIn allows you to search and join groups that connect people with common professional interests. ![]() Networking with those in your industry and building strong connections is crucial to success. LinkedIn offers a convenient platform for building a professional network Making your LinkedIn profile complete and current is a must to project a proactive image to employers. Recruiters may see applicants who aren’t on LinkedIn or who don’t update and maintain their profiles as not taking their career or professional image seriously. Employers also check out a candidate’s online presences as a routine part of the hiring process. Nowadays, many recruiters and hiring managers use LinkedIn to search for candidates with skills and experiences that match their opening. Gone are the days of want-ads full of great jobs that all candidates apply for on an equal footing. Here are some compelling reasons why you should have a LinkedIn profile: The hiring process has changed dramatically Because everyone and their grandmother seem to have a LinkedIn profile these days, it is important for both active job-seekers and those not currently seeking employment to be aware of the power and opportunities LinkedIn can offer. According to Forbes, LinkedIn is the largest professional network in the world-the site was specifically designed to strengthen connections between industry professionals. Why should you use LinkedIn to attract employers?ĭespite being one of the most globally popular social media platforms, a lot of people still have no idea what LinkedIn is and how using this tool can help when exploring career options or simply searching for jobs. Let’s discuss the reasons you should be using LinkedIn to promote yourself and go over some content and structure tips for that will make your LinkedIn profile impressive and attractive to your target viewers. LinkedIn is not only a job-seeking tool-it is also a platform where users build their personal brands. Your profile should thus be interesting and attention-grabbing so that these busy professionals will take the time to read through all the information in your profile. Even more important for job-seekers, an outstanding profile will help you engage with your target audience of hiring professionals, including recruiters, HR staff, and hiring managers, as they scan the field of LinkedIn profiles for qualified candidates. A strong and attractive LinkedIn profile is crucial for connecting with people in your network. ![]() Expedia verified reviews Hyatt Place Santa Cruz Seaside Inn & Suites Courtyard by Marriott Santa Cruz.
