WolframAlpha (only the screencast for now)

Here, an impressive demo of what it promises to be the next big thing on the Internet. Wolfram Alpha is been created by [[Stephen Wolfram]], creator of [[Mathematica]] and it is supposed to become available starting from May 2010. It seems like it could be an amazing example of data mining technology and could prove very useful for bridging technical knowledge to every day curiosities.
And here, a review of a first public demo run.

EDIT [2009/05/17]. Seems the service is online starting from yesterday. You can calculate things like Normality of 37%HCl or your exact age in seconds.

What I Think About When I Think About Manuscripts – I, Editor – Henry Gee’s blog on Nature Network

Perhaps what I am getting at is that scientific papers tend to be static. The best literature – of any kind – has a beginning, a middle and an end, in which the protagonists undertake some kind of journey, whether geographical or spiritual, and are changed by their experiences. In scientific papers, the results often give us no clue to the back story – the reason why the researchers were studying this system or that, and the tale of chances and mistakes and serendipity that led them to that point. The only readable parts tend to be the introduction, in which literature is summarized (a classic case of telling but not showing) and the discussion (in which the new result is integrated into what is already known).

Project GREAT: General Relativity Einstein/Essen Anniversary Test

This is kind of old (goes back to 2005/7) but fascinating. This guy got 6 atomic clock. He left 3 at home and he took the other three to a weekend outing on Mt. Rainier (~1500 meters above) – along with his three kids, of course. All this to test one of most famous Einstein’s postulates. Here’s the link.. Don’t miss the family pictures section.

Free unmissable Windows software that will make your computer life easier.

Whatever your job, there is a good chance you’ll spend lots of time sitting in front of a computer. If you do lots of data analysis, as I do lately, then you’ll find yourself in front of the monitor for most of the day. I’ll use this and the following few posts to introduce some softwares that are going to dramatically improve your productivity – and make your digital life easier. Web is full of list with dozens of best freeware software so I have no intention of making just another one; rather I will suggest one software per category. If you know of something better feel free to leave a comment to this post. I’ll start with this post with some more general softwares, useful to anyone. In the next one I will talk of more scientific-oriented softwares.

Fancy Pull-quotes (v0.85)

Installation.
Simply download the plugin, unzip it and copy the php file in the plugin directory of your wordpress installation. Then activate it from the admin panel and you are ready to go. The plugin is fully customizable from a page in the admin control panel.Note: if you are upgrading the plugin from an older version I recommend to first click the “restore all options to default” link.

How to use.
Simply surround the text that you want to see as pull-quote by the following tags: <!--pull--> and <!--/pull-->. The plugin will automatically scan your post for the text included with these tags and treat it as pull-quotes. Getting those
nice
effects is
as easy as that!
Getting those nice effects is as easy as that! If you don’t like the tags as they are or if you want to change the look of the pulled quote, you can do it from the control page in the admin panel of wordpress. The quote is formatted using a CSS definition: if you are an advanced user (i.e. if you know a bit of CSS) you can hack the CSS style in every part.

Detailed instruction.

Open and Close tags: you can define which tag to be used as markers for the pulled quote. Default are <!–pull–> and <!–/pull–>. These tags are transparent by default meaning that if you check the “Mirror quote” option you can activate or inactivate the plugin at any time without changing the layout of your posts.

Background Color: Choose background color. Use same color as your normal background to make it transparent.

Text Color: Choose text color. You can use hexadecimal values (for instance: #0AFF44)

Max Width: specifies the maximal width allowed

Pullquote position: pullquote position in the page (left or right)

Border color, size, style: define border properties

Mirror quote: leave unchecked if you want to use a quote that won’t show in the text of your post (for instance: if you want to have the pullquote to appear at the very top of your post you can uncheck the “mirror quote” checkbox and insert the pulled quoted as first thing in your wordpress post)

Version.
Current version of the plugin is 0.85, released on 4.19.2007. The plugin has been tested and working WP 2.0.x and 2.1.x. If you have other experience on other versions of WP please leave a comment here and I’ll udate this paragraph.

License.
The plug-in is released under GPL license, meaning it’s free. If you like it or if you need help feel free to leave a comment here. (did you note that I installed some ads on this page? maybe you can find a couple of minute to check if there is anything interesting to you…)
Take a look also to my other plugin, Alt-to-Legend.

Enjoy!

Wikipedia, Citizendium, Frankenstein and the golem.

[image by fd]Everybody knows Wikipedia so no need for introduction. Let’s just say that of the many very different opinions I have heard about it – placeable everywhere in the range from most celebratory to destructive – there is a quote that I find very attractive:

Wikipedia should not work, but it does!

This quote, which I believe is attributable to one of the fathers of wikpedia, Larry Sanger, says much about the on-line encyclopedia:

    Wikipedia is an experiment. A crazy one. Most people would have thought that the wiki affair would have been a failure but in fact it is now after only few years the biggest encyclopedia available nowadays.
    Nobody really knows how and why wikipedia works.

Alt to Legend (v0.50)

This is a neat Plugin!This is a neat Plugin!
Installation.
Simply download the plugin, unzip it and copy the php file in the plugin directory of your wordpress installation. Then activate it from the admin panel. You can customize the behavior of Alt-2-Legend from a new panel that will appear under the ‘Option’ page in the admin panel.

How to use.
Once your plugin is installed, it is ready to use. Simply insert an image in your post as you normally do and provide a description in the title textbox of the popup window. The text specified in the alt field or title field (your choice) will appear under the image. You can then decide the relative position of the images in the posts under the option page in the admin panel. Image can float always left, always right or according to the align parameter (meaning different post by post if you wish so).

Version.
Current version of the plugin is 0.5, released on 5.10.2009. The plugin has been tested only on WP 2.7.1. If you have other experience on other versions of WP please leave a comment here.

License.
The plug-in is released under GPL license, meaning it’s free. If you like it or if you need help feel free to leave a comment here – and hopefully I will get some monetary feedback from the people who will find interesting ads to click on.

Picture by ToNo's worldX PRIZE Foundation is a non-profit foundation based in Santa Monica, CA. They gained popularity few years ago when they listed and subsequently awarded the Ansari X Prize. They offered US$10mln to the first private institution that would be able to launch a reusable manned spacecraft into space twice within two weeks. The price was awarded in 2004 and had a lot of echo. After that success, the X-Prize fondation grew stronger so that now they can efford to offer a new batch of prizes, related to different disciplines. One of them is the Archon X Prize for Genomics that also happened to be the largest medical prize in history. The prize is described as

A multi-million dollar incentive to create technology that can successfully map 100 human genomes in 10 days. The prize is designed to usher in a new era of personalized preventative medicine and stimulate new avenues of research and development of medical sciences.

What does it take to make a good Scientist?

Image by *Kazze*I just saw something on the weekly edition of Nature Jobs that made me very happy. It is something that I was waiting to see since a long time. In May 2006 Georgia Chenevix-Trench felt like sharing some of her wisdom with the youngest public of the journal Nature. In the (often embarrassing) portion of the journal called Nature Jobs, she published a Decalogue with “tips for students”; goal of the letter was to provide prospective PhD students with rules of thumbs that would help out having a successful career. Sadly enough most of them were embracing the concept of hard work and only marginally important skills such as creativity, imagination, collaborative science.
