I have a lecture next week which will discuss HTML markup. I have lots of notes and examples for XHTML 1.0 and CSS 2 which I think students should read through for some deeper learning rather than be presented in a lecture. I have instead decided to show this video. On searching,I also found this presentation from Google I/0 2009 (the Google developer’s conference) which talks about what’s coming next!
It’s very early days and HTML 5 seems to be being developed in quite a piecemeal way with browser developers emphasizing some features and not others. It may be several years before all of HTML 5 is supported in all browsers, but that doesn’t mean that my students shouldn’t know that it’s coming.
I am grateful to my friend and former Swansea colleague Dr Farzin Deravi of University of Kent at Canterbury who read my blog post on Euler’s identity (“The Most Beautiful Equation in the World”) via Facebook and told me about this video proof of the equation:
It’s well put together, but for me crucially omits the vital step that substitutes cos ? = -1 and sin ? = 0 to reduce ei? = cos ? – i sin ? to ei? = –1 + 0 which of course can be rearranged to give ei? + 1 = 0.
This was not the only “Euler Video” available on YouTube, looking further, I found this nice example, also a proof of Euler’s identity, that shows what you can do with a tablet and screen recording software.
Two very inspirational demonstrations of the power of video in the teaching of mathematical concepts.
This video, from the YouTube series “Simon’s Cat” was featured on last week’s Culture Show on BBC 2 [in the UK]. There are two others, equally great and hopefully more to come. All cat lovers will get a shiver of recognition when watching this!
As reported yesterday, I’ve been catching up with a number of presentations from the Google I/O 2008 conference. However, I just had to draw particular attention to one of the highlights which is this recording of a very entertaining presentation from Chris di Bona who is Open Source Programs Manager at Google. In an engaging, anecdotal style, Chris covers the history and philosophy of Open Source (which includes a name check for Swansea’s very own Alan Cox) and how Google relies on it, promotes it and develops some of its own. The video is on and the original link to the talk includes the slides (which I assume are re-usable).
On on Tuesday 18th September, Google announced the arrival of a new collaborative presentation tool which they call simply presentation . Annew member of the Google Docs suite (which already includes a collaborative Word Processor and a Spreadsheet application), presentation provides a web-based tool for creating and developing presentations. It’s not as capable as PowerPoint, but probably passes the 80-20 rule. Plus it’s collaborative (you can share presentation development duties with others) and web publishable. Here’s a quick and dirty presentation I made to test the tool and its sharing capabilities. If you’d like to test it’s collaboration capabilities, leave me a comment with your email and I’ll share it with you. In a carefully timed release, our friends at Common Craft, released another “plain english” video to explain why collaborative tools like Google Docs are important. It’s Google centric (presumably Google commisioned the video), but the central tenets apply to other collaborative systems even sharepoint. Are you listening dear colleagues of mine!
It’s been a while but I’m sort of back in harness after my vacation (even if actually at home in my pyjamas). One of the issues that always occurs after a period away is dealing with the email after a period away. To this end, this video by Merlin Mann of 43folders may help. It provides some useful tips about how to deal with after-vacation email as well as the ongoing problem of dealing with email on a daily basis. It comes down to a simple strategy for processing email: empty the email inbox every time that you visit it. You do this by some variation of a processing procedure that does one of these five things with each message:
delete (or archive)
Watch the video for more detail and for the interesting discussion (with Google knowledge workers) and be inspired!
Just published by Lee LeFever on the CommonCraft site is a new “paper works” video on Web 2.0. This time its social networking: which apparently is all about finding a life partner or finding a job. Since, in my case, I’m happy with both, I fear that social networking has little to offer. Still, enjoy the video.
