Spectre’s Touch of Evil

The opening shot of Sam Mendes second James Bond movie, the 24th iteration 'Spectre', appears to be an unbroken take of about seven or eight minutes. This is a fluid master shot which at first that appears to have made using a Steadicam, although later in the take it may have fairly seamlessly cut to a drone shot (as there are elements to this shot which would have been impossible with a crane). Anyhow this particular opening piqued my curiosity, because unlike ...

Water (5)

Tuesday was World Water Day 2011 and the theme for this year was ‘Water for Cities’. The theme for this weeks blogs posts will therefore be all about water. So far, we have been focusing on the fact that water has a much higher boiling point than is predicted and that the reason could be pinned down to electronegativity.   Image kindly reproduced according to the licence at: http://en.wikipedia.org/wiki/File:3D_model_hydrogen_bonds_in_water.jpg You may also remember that yesterday I posted a question asking: ‘What causes electronegativity?’ Well, electronegativity is caused by ...

Reverse Friction?

  I have always thought of friction as being a physics topic but it has been proposed by scientists in the University of California that a chemical force could be used to reduced friction. Chemical force? What do I mean by this? I am writing about intermolecular forces, the force that 'holds' atom or molecules together. As you know there are three intermolecular forces: Hydrogen bonds (the strongest). Permanent dipole - dipole interactions. Van der Waals / London dispersion forces (the weakest). It is the ...

Trans Fatty Acids

By Sunday, August 29, 2010 , , , , 0

  Over the last 24 months or so you may have noticed that many of the food products you consume have labels relating to 'trans fatty acids', labels such as 'contains no trans fatty acids' are now common place. But what does this label refer to? Well, foods contain fats. That we know. Some of the fats will be saturated, others unsaturated. It has been know for some while tht saturated fatty acids are unhealthy. It is the unsaturated fats that this post is ...
