Entropic gravity is back in the news. Various science blogs again carry headlines dealing with entropic gravity. This time round, the reports are less favorable towards the idea of gravity being entropic, with headlines like Experiments Show Gravity Is Not an Emergent Phenomenon screaming for attention.

Sounds like a death stab to Erik Verlinde's brainchild, right?

Ok, I have warned you. Brace yourself. I am going to argue against what many believe to be the most fundamental law of physics. A sacrosanct law. A law that you experience everyday and that is so obviously true that no one should meddle with it. You all know this law. It's the law referred to as 'the second'. The second law of thermodynamics.

Equations don't sell. Pop science editors tell us that each equation added to a book halves its sales figure. If this is true, Sir Roger Penrose's Cycles of Time, which was recently released in the US, and which I can testify sold at least one copy, would have sold by the billions if only the editor would have scrapped half of the equations.
The British have their Copley medals, the French the CNRS Gold medals, the Germans have Leibniz awards, and the Dutch... they have their Spinoza prizes. Each year three to four Spinoza laureates split a total of ten million euros (14.3 mln US$). In the Netherlands the prize, named after the Dutch philosopher Baruch Spinoza, is often referred to as the 'Dutch Nobel Prize'. No other Dutch science prize comes close, neither in monetary amount nor in prestige. 

Amongst the three winners of this year's Spinoza prize is theoretical physicist Erik Verlinde.* A well-known name for readers of this column.

Is stupidity rising? Are we witnessing an alarming proliferation of irrationality and an exuberance of ignorance? 
Some subjects I try to avoid in this blog. But this one seems to become increasingly difficult to escape. Since my interview at Philosophy-To-Go, I regularly get questions about the physics of free will. These questions range from
"Does free will exist given that the laws of physics are deterministic?"
to the more suggestive
"Is our free will based on quantum indeterminism?"
and the more confrontational
