I used to post on this blog very abstruse graphs from time to time, asking readers to guess what they represented. I don't know why I stopped it - it is fun. So here is a very colourful graph for you today. You are asked to guess what it represents. 



I am reluctant to provide any hints, as I do not want to cripple your fantasy. But if you really want to try and guess something close to the truth, this graph represents a slice of a multi-dimensional space, and the information in the lines and in the coloured map is not directly related. Have a shot in the comments thread! (One further hint: you stand no chance of figuring this out).

The Need to Update the Article

The purpose of trying to assess the understanding of my students on alcoholic beverages, unexpectedly led to the need to update the article they read.

The Process


Although I have done my share of writing on Dr. Oz (much of it humorous, and some just in poor taste), the following has nothing to do with me.
I used to work with a programming language called Business Basic.  It was descended through several generations from the original Dartmouth BASIC.  Like all primitive 3rd generation languages early Business Basic languished in the era of line numbered source code, shared data spaces, and loose typing.  Modern Business Basic languages now offer object-oriented programming features.  And after much grousing and arguing among the aging user base we finally got rid of the line numbers in the late 1990s or early 2000s, although I joined the early adopters who simply coded outside the interpreter without line numbers.

On April 11th 2015 I delivered a presentation on the subject of Quantum Gravity in which I questioned the basic assumption that quantum is more fundamental than relativity.  Relativization is the name for the approach I propose.  In a nutshell let us try treating relativity as the more fundamental set of principles and make quantum field theory obey those.  The talk was well received.    There is still lots of work do on this and a lifetime to do it in, but the approach is now firmly not "crackpot".  Indeed as the money plot from my presentation shows this approach gets a very nice result for the behavior of black holes. 

The talk:

Growing new connections in your brain is more essential to learning than strengthening established connections. You may know how to be a tax lawyer because you've spent years strengthening your old tax law connections, but these are utterly useless when you take up ballroom dancing to find yourself a mate.

A lot of people are now scared of BMPEA because there are not any human studies. They say that there are only a handful of preclinical studies. Gee, thanks for saying that the research done by 99% of biomedical scientists is bogus. A recent study suggests that, based on recommended servings, users of certain supplements that contain BMPEA would take about 1 mg/kg of BMPEA .

Space is always on the mind of a veteran NASA astronaut Brian Duffy. The key figure in an aerospace company Orbital ATK and a Space Shuttle commander is extremely keen on flying to space again.

The enthusiasm emanating from him for the future journeys beyond Earth, which we all patiently wait for, is heartily thrilling. In an interview with me, Duffy talks his successful astronaut career, post-NASA endeavors and his love for space.

Flakka - "gravel" - is all the rage with amateur druggies in Florida and Texas and wherever else people who have watched a lot of "Breaking Bad" do home chemistry. It is made from alpha-PVP, which is a chemical cousin of cathinone, found in bath salts.
