Curie Point Heat Engine: when the magnet on the end of the wire heats up to a particular temperature (the Curie point) its magnetic field is temporarily lost until it cools. This engine design uses a second magnet to pull the swinging magnet back into the heat source once the magnetic field is reestablished. Repetition of this process creates mechanical motion as long as the heat source is fueled. ➡️ Follow the link in my profile for info on where to get many of the amazing devices featured here on @physicsfun #PierreCurie #curiepoint #magnetism #magnets #magneticfield #heat #heatengine #physics #physicstoy #candle #neodymium #science #scienceisawesome

video length for online courses

Dear colleagues,

I am collaborating on a project comparing the efficacy of two types of instructional videos. We are looking for literature that describes similar research. For example, a study might compare students who have watched voice-over ppt slides and students who have watched Khan-style videos, examining students’ content knowledge and/or some affective constructs. Alternatively, a study might compare the lengths or speeds of only one type of video.

Given the dearth of literature addressing these variables, I am hoping this community can help us uncover some additional research for our literature review. I am happy to compile and share everything that is shared with me over the coming days.

It is impossible to please everyone all the time—at least that is what survey results suggest. There are several takeaways to this study: Video length matters, especially as a consideration before the video is viewed. Timestamps should be included in video creation, or it is highly likely that the video will not be viewed. The video player is key here, as some video players include video length, while others do not. Videos that exceed four minutes are unlikely to be viewed unless they are required. Voice quality in narration matters. Although preference in type of voice inevitably varies, the actor’s voice is noticed over production value. It is important that the narrator speaks evenly and clearly. For brief how-to videos, there is a small preference for screencast instructional videos over a narrative roleplay scenario. The results of the survey indicate that roleplay videos should be wellproduced, brief, and high quality. However, what constitutes high quality is not very well established.15 Finally, screencast videos should include an example scenario, however brief, to ground the viewer in the task.

fake news and video

Computer Scientists Demonstrate The Potential For Faking Video

As a team out of the University of Washington explains in a new paper titled “Synthesizing Obama: Learning Lip Sync from Audio,” they’ve made several fake videos of Obama.



Fake news: you ain’t seen nothing yet

Generating convincing audio and video of fake events, July 1, 2017

took only a few days to create the clip on a desktop computer using a generative adversarial network (GAN), a type of machine-learning algorithm.

Faith in written information is under attack in some quarters by the spread of what is loosely known as “fake news”. But images and sound recordings retain for many an inherent trustworthiness. GANs are part of a technological wave that threatens this credibility.

Amnesty International is already grappling with some of these issues. Its Citizen Evidence Lab verifies videos and images of alleged human-rights abuses. It uses Google Earth to examine background landscapes and to test whether a video or image was captured when and where it claims. It uses Wolfram Alpha, a search engine, to cross-reference historical weather conditions against those claimed in the video. Amnesty’s work mostly catches old videos that are being labelled as a new atrocity, but it will have to watch out for generated video, too. Cryptography could also help to verify that content has come from a trusted organisation. Media could be signed with a unique key that only the signing organisation—or the originating device—possesses.

archive video tapes

Videotapes Are Becoming Unwatchable As Archivists Work To Save Them

Scott Greenstone

Kidd and the others are archivists and preservationists, and they’re part of a group called XFR Collective (pronounced Transfer Collective). Most work professionally, but they volunteer their free time to do this.

That’s because research suggests that tapes like this aren’t going to live beyond 15 to 20 years. Some call this the “magnetic media crisis,” and archivists, preservationists, and librarians like the ones in the XFR Collective are trying to reverse it.

Some are old videos of police brutality; others are just weddings or old public access TV that isn’t saved anywhere else. All tapes are from people who want their content to be publicly available, and after the tapes are transferred, they’re stored on the nonprofit Internet Archive. To date, they’ve transferred 155 tapes—67 hours in total.

Of course, this doesn’t guarantee that they will be saved forever. Digital has its own problems, and Lukk says that some film preservationists argue we should be looking back to before magnetic media for stable preservation — many Hollywood films, for instance, are often stored on film in salt mines, where they can last 100 years.
