SCIENCE AND TECHNOLOGY


A century ago communication across any distance was dependent upon the telegraph or letters . No jets crossed the ocean , no television pictures enabled us instantly to see events in any part of the world, there were no worldwide telephone networks and no computers . It is just a short lifetime since humanity first travelled into space and discovered how fragile our planet looks .
FROM FIREWORKS TO THE MOON
At first glance you might think that there couldn’t possibly be anything common between a 13th century festival in China and the Apollo 11 moon landing in 1969. However , there is a link and that is that they both relied on the use of rockets.
The Chinese first developed rockets by filling bamboo tubes with an explosive made from saltpetre, charcoal , and sulphur . The sealed tubes would be thrown onto fires during celebrations because it was thought that the loud explosions would protect them . It was not long before the ancient Chinese realised the military potential of these devices and primitive rockets were used to repel a Mongol invasion in 1232 AD. Word of these new amazing weapons quickly spread around the world and soon rockets were being used in military operations in North Africa and Europe . During the 15th and 16th centuries they were widely used in naval battles

Education

Imagine trying to learn to draw from listening to a lecture. You must draw, draw, draw, and with time and tutoring, will improve. This is a truism, just like saying "reading is valuable." I imagine nobody complains about children spending too much time working. If anything the contrary complaint rings loudly. What I don't begin to know is the ideal breakdown, according to age, of reading, listening to instruction, and working or hands-on time. What about technology in excess? Before the age of printing and cheap paper, comparatively few people could become learned. Now, theoretically, our electronic age makes learning easier than ever. Well, technology is indisputably better. We can store and retrieve data much more efficiently. We can communicate in a flash. But still, at the basic level, we must be well grounded -- we must possess common sense, civil manners, frank discussion skills, reasoning abilities, and moral fiber

hallucinations. They concluded from this study that sensory deprivation triggered the release of serotonin, which actually altered the way the monks experienced the world. The application of such research has improved the lives of many people, because drugs have been developed stimulating or blocking certain neurotransmitters. Psychologists however, consider the role of neurotransmitters on behavior, but do not solely rely on it to explain behavior. Brain technology has developed rapidly during the past century and is now used extensively in neuropsychology because it provides an opportunity to study the active brain. EEG ­ Prints out brainwaves, registers patterns of voltage change in the brain. PET scan ­ monitors radioactive glucose metabolism in brain. Produces colored maps of brain activity. Can record ongoing activity. fMRI ­ provides 3D pictures of the brain structures, using magnetic fields and radio waves. It shows actual brain

ELT Methodology (FLGR.01.041) 27.12.2012 Home Assignments. I Youtube clips: · A vision of K-12 students I personally think that Estonian learners are also digital learners. They spend more time at the computers or laptops or iPads etc. than read books or move outside. And another thing is that teachers are less capable in using technological appliances. But the latter mentioned fact is an advantage for us ­ teachers as well. It gives us an opportunity to provide our students to experience success. They can help and assist us if we need some technological help. Another thing is that in schools, in classes generally students are not allowed to use their appliances, so it means they have to communicate verbally as well. I think that teachers should be creative to blend so-called digital le

And it’s also still a book about designing anything that people need to interact with, whether it’s a microwave oven, a mobile app, or an ATM. The basic principles are the same even if the landscape has changed, because usability is about people and how they understand and use things, not abouttechnology.And while technology often changesquickly,people change veryslowly.3 3 There’sawonderfulNorwegianvideo(withsubtitles)aboutthisthatshowsamonkgettinghelpashestrugglestousethe newfangled“book.”(Searchfor“medievalhelpdesk”onYouTube.)
