Too many kids as well as teenagers and adults have problems with study. Today's meetup will inform you about the basics in STUDY TECHNOLOGY that provides an understanding of the basics of learning and supplies exact ways to overcome all the pitfalls one can encounter during study. This is applicable to young children, teenagers (or their parents that are trying to help them) and adults alike. Study Technology shows how one studies in order to comprehend a subject so one can apply it. Laws on which learning is based and workable methods have also been discovered for anyone to apply for themselves or when teaching others. Too many students graduate from school and college unable to put to use what they’ve learned in school. It’s not that they’re stupid or that their teachers didn’t know how to teach. More than likely it traces back to the one thing missing from most educations—learning how to learn in the first place. We all went to school, yet isn’t it odd that no one taught us how to study? The information presented at this meetup can help anyone improve others or his own ability to learn. It is a practical tool that parents and teachers alike can use to enhance a child's study performance. You’ll learn the barriers that lie between your own or a child's education. And you will very quickly learn how to overcome them. This technology will enable you or a child to pursue any subject with skill and confidence. Teachers who have "hard to handle/distributive " or slow learners in class will absolutely love the amazing turn around most often seen in improved behaviour and student performance in class. If you or your child has difficulties at school (or learning new things at work or online) than this meetup is important to you. If you can not make it to our meetup than contact the organizer and arrange it to suit your time. This technology can if one was to live far away be taught online. (extension course) You may offcourse also opt to have this technology taught to your own child by experienced volunteeer staff or learn about this yourself and transfer this knowledge to those you want to have better grades. Yes it is possible to improve anyone's study performance. All it takes is just 5 steps. See you at this meetup. Pam

Come along first to optional dinner at TGIF Southland at 7pm followed by optional film Michael which starts at 9.15pm. ## TGI Fridays DOWN Under Following the success of TGI Fridays in the States, the iconic bar and grill restaurant arrived in Australia in 1995. With loaded potato skins, flame-grilled ribs and a range of colourful cocktails on the menu, it was something never seen before. Aussies fell in love with TGI Fridays though, quickly becoming a favourite place to celebrate occasions or to enjoy a fun night out with friends and family. ## Today Now with 18 locations around Australia, we are 100% Australian-owned and independent, operating as the licensee of the TGI Fridays brand. Just like at the first TGI Fridays in 60's New York, we're serving up delicious American food and handcrafted cocktails to Fridays fans across the country. We continue to celebrate our famous Happy Hour every day and sling our bestselling Long Island Iced Teas. Visit us at your favourite location and get that Fridays feeling! So table booked under Andrew Goodwin (ph: 0424453134) for optional dinner at 7pm at TGIF Southland. Here is a copy of the menu. [https://www.tgifridays.com.au/menu/food/southland/](https://www.tgifridays.com.au/menu/food/southland/) Then just very roughly at 8.30pm we can then go to buy tickets to the 9.15pm VPremium session at Village Southland which is very closeby (for those coming to the film.) Here is the synopsis. SynopsisMICHAEL is the cinematic portrayal of the life and legacy of one of the most influential artists the world has ever known. The film tells the story of Michael Jackson's life beyond the music, tracing his journey from the discovery of his extraordinary talent as the lead of the Jackson Five, to the visionary artist whose creative ambition fueled a relentless pursuit to become the biggest entertainer in the world. Highlighting both his life off-stage and some of the most iconic performances from his early solo career, the film gives audiences a front-row seat to Michael Jackson as never before. This is where his story begins.

The optimum computing machine is a subject many of us have studied. If you were building one how would you design it? First the computer should be able to compute with perfect accuracy on any problem in the universe and produce answers which were always and invariably right. Second the computer would have to be swift, working much more quickly than the problem and process could be vocally articulated. Third the computer would have to be able to handle large numbers of variables and large numbers of problems simultaneously. Forth, the computer would have to be able to evaluate its own data and there would have to remain available within it not only a record of its former conclusions but the evaluations leading to those conclusions. Fifth, the computer would have to be served by a memory bank of nearly infinite capacity and would have to be available to the analytical portion of the computer in the smallest fractions of a second. Sixth, the computer would have to be able to rearrange former conclusions or alter them in the light of new experience. Seventh, the computer would need no exterior director, but would be entirely self determined about its programing guided only by the necessity –value of the solution which it itself would determine. Eight the computer should be self servicing and self arming against present and future damage and would be able to estimate future damage. Ninth the computer should be served by perception by which it could determine necessity –value. Tenth ,the memory bank should store perceptions as perceived ,consecutive with time received with the smallest possible time divisions between perception .It would then store in color-Visio (moving),tone audio (flowing),odor ,tactile and self sensation ,all of them cross –coordinated . Eleventh, for the purposes of solutions, it would have to be able to create new situations and imagine new perceptions hitherto not perceived and should be able to conceive these to itself in terms of tone –audio ,color-visio ,odor, tactile, and self sensation –and should be able to file anything so conceived as imagined ,labeled “memories” Twelfth, the entire machine should be portable. It might be somewhat astonishing at first to conceive such a computer .But the fact is, the machine is in existence .There are billions of them in use today and many ,many more billions have been made and used in the past . In fact you’ve got one .for we are dealing with the human mind. L.RON .HUBBARD Do you want to learn how the mind works?Then do not miss this meetup. RSVP now !!
