The red squares represent the area that would be enough for solar power plants to produce a quantity of electricity consumed by the world today, in Europe (EU-25) and Germany (De).
Amazing fact/quote: ‘in just six hours, the world’s deserts receive more energy from the sun than humankind consumes in a year.’
From Wikipedia (which gives the history of the associated project plus it’s pros and cons as well as the remarkable graphic above):
“The DESERTEC concept was originated with Dr Gerhard Knies, a German particle physicist and founder of the Trans-Mediterranean Renewable Energy Cooperation (TREC) network of researchers. In 1986, in the wake of the Chernobyl nuclear accident, he was searching for a potential alternative source of clean energy and arrived at the following remarkable conclusion: in just six hours, the world’s deserts receive more energy from the sun than humankind consumes in a year.
The DESERTEC concept was developed further by Trans-Mediterranean Renewable Energy Cooperation (TREC) – an international network of scientists, experts and politicians from the field of renewable energies – founded in 2003 by the Club of Rome and the National Energy Research Center Jordan. One of the most famous members was Prince Hassan bin Talal of Jordan. In 2009, TREC emerged to the non-profit DESERTEC Foundation.”

Interesting and lengthy post by Jon Gruber, motivated by the recent Apple World Wide Developers Conference (WWDC), which discusses Apple’s CEO Tim Cook’s assertion that:
“Apple engineers platforms, devices, and services together. We do this so that we can create a seamless experience for our users that is unparalleled in the industry. This is something only Apple can do.”
Is this true, though? Is Apple the only company that can do this? I think it’s inarguable that they’re the only company that is doing it, but Cook is saying they’re the only company that can.
Apple, Google, and Microsoft each offer all three things: devices, services, and platforms. But each has a different starting point. With Apple it’s the device. With Microsoft it’s the platform. With Google it’s the services.
And thus all three companies can brag about things that only they can achieve. What Cook is arguing, and which I would say last week’s WWDC exemplified more so than at any point since the original iPhone in 2007, is that there are more advantages to Apple’s approach.
Or, better put, there are potentially more advantages to Apple’s approach, and Tim Cook seems maniacally focused on tapping into that potential.

More on the above graphic can be found here, including:
The vast majority of people will get their science news from online news site articles, and rarely delve into the research that the article is based on. Personally, I think it’s therefore important that people are capable of spotting bad scientific methods, or realising when articles are being economical with the conclusions drawn from research, and that’s what this graphic aims to do. Note that this is not a comprehensive overview…

I was fascinated to read that (see here):
More than 10,000 people have signed up for an online course to study the work of Nobel Prize-winning physicist Professor Peter Higgs.
The free seven-week course, called The Discovery of the Higgs boson, begins this week and is being run by the University of Edinburgh where Prof Higgs worked when he developed the “God particle” theory.
The course is being run on the FutureLearn platform, a partnership of 23 universities.
The requirements seem quite modest: The course requires a basic level of mathematical skills, at the level of a final-year school pupil. A basic knowledge of physics is helpful, but not required.
Although it’s already started, it may be worthwhile joining if you’re interested in the topic as just 2 hours a week is needed. The link to the course is here.
I’ve previously written about the Higgs here and here (I did academic research in this area for over 10 years before moving to the commercial sector).

In case you’ve not seen this before, be patient and wait until the end, just 2 mins, and you’ll be very surprised! It shows just how easily you can get (cleverly) fooled.
More on optical illusions here.

Following on from here, I’ve just noticed that Volume Three of the Feynman Lectures (Quantum Mechanics) is now available online.
Once again, a really fantastic version and all free too!
Hopefully this helps ignite the imagination of the next Feynman…

A nice video version of the ‘explanation’ of the Higgs field/particle (discovered earlier this year) that’s based on an analogy with people at a party and the different ways they interact with each other. See also here.
I’m very familiar with this area (my postgraduate research was in particle physics) so it’s not easy to appreciate how useful or otherwise these mini-explanations are. Books are available for longer and more detailed explanations, at various levels, but these are obviously not for everyone.
In fact there are so many distractions these days, I guess getting a few minutes of someone’s time and getting a flavour of the concepts over is quite an impressive achievement!
For more info, there’s a very accessible and recent account of this important breakthrough here.
