Is this the shape of the Universe?


This is the E8 pattern, the most intricate shape known to mathematics. It is an eight-dimensional mathematical pattern with 248 points first found in 1887, but only fully understood by mathematicians this year after workings, that, if written out in small print, would cover an area "the size of Manhattan".

E8 encapsulates the symmetries of a geometric object that is 57-dimensional and is itself is 248-dimensional.
Garrett Lisi, a scientist who rather splendidly seems to spend most of his time surfing or snowboarding, reckons that the mathematics of particle physics conforms to the same pattern, and he predicts that a further twenty particles will be discovered when the Large Hadron Collider comes online next year.
Exciting times to be a physicist!

I have replied to you on th Heffer thread. Your silence on the goings on I refer to in Georgia leads me to wonder if abuses only matter to you when they are committed by Russians

Cicero,

Why has there been so little public debate about the particle accelaration experiments of the Large Hadron Collider given that there is an (admittedly awfully slender) chance that it might destroy the Earth and indeed possibly the Universe? Does the upside potential discovery really justify the huge gamble?

Well, it could be another "cold fusion" on the other hand very few theories have been intially greeted with enthusiasm- including Einsteins.

I think the "risk" of the LHC is so tiny that it is one that I am happy to take. We would have really got to have made some massive errors in the laws of physics to be at risk of any kind of environmental, let alone existential threat.

Your sanguine attitude is understandable, but if we are so certain that we have grasped the fundamental 'laws' of physics already, why is the experiment awfully vital? If we have lack such certainty then is the experiment as 'safe' as we presently hope? I am concerned that those who are assessing the risk appear to be the most enthusiastic about pushing the experiment. Rather like letting bright traders work without risk oversight, their very brilliance and energy may be the source of our troubles! Wheatley

I just took that drawing and added another circles of 30 points around the outside and connected the dots.
Does that mean I just created an even more intricate shape?

Since just looking at something changes it...Maybe I also changed the basic physical principles of the universe too. ;-)

The link is fine, it's just the way blogspot renders it. You can cut and paste it normally.

Cicero ReDux

By Special Request of Baroness Scott and Mark Valladares... Cicero's Songs returns: bigger, longer and uncut.
October 1st marked the half way point of the Estonian Presidency of the European Union.  Perhaps for many people such an anniversary is of passing interest at best.  Yet the conduct of the Estonian Presidency is reinforcing just how forward looking and innovative the most northerly of the Baltic States has become.
Estonia is a country that wants to live in the future, and with its openness and innovation, that future seems a lot closer than almost anywhere else in Europe
It is not that Estonia does not “do” the past: the picturesque cobbled streets of old Tallinn have tourist crowds a-plenty enjoying the mediaeval architecture in an Indian summer of sunshine and blue skies.  The real point is that Estonia refuses to be a prisoner of its past. Lennart Meri, Estonia’s President in the 1990s- who spent years of his childhood in Siberia- once told me that the country had to conc…

Trump and Brexit are the Pearl Harbor and the Fall of Singapore in Russia's Hybrid war against the West.

In December 1941, Imperial Japan launched a surprise attack on the United States at Pearl Harbor. After the subsequent declaration of war, within three days, the Japanese had sunk the British warships, HMS Prince of Wales and HMS Repulse, and the rapid Japanese attack led to the surrender of Hong Kong on Christmas Day 1941 and the fall of Singapore only two months after Pearl Harbor. These were the opening blows in the long war of the Pacific that cost over 30,000,000 lives and was only ended with the detonations above Hiroshima and Nagasaki.

"History doesn't often repeat itself, but it rhymes" is an aphorism attributed to Mark Twain, and in a way it seems quite appropriate when we survey the current scene. 

In 1941, Imperial Japan, knowing its own weakness, chose a non-conventional form of war, the surprise attack. Since the end of his first Presidential term, Vladimir Putin, knowing Russia's weakness, has also chosen non-conventional ways to promote his domestic powe…

The American National nightmare becomes a global nightmare

It is a basic contention of this blog that Donald J Trump is not fit for office.

A crooked real estate developer with a dubious past and highly questionable finances. he has systematically lied his way into financial or other advantage. His personal qualities include vulgarity, sexual assault allegations and fraudulent statements on almost every subject. 

He lost the popular vote by nearly three million votes.

He has, of course, been under criminal investigation practically since before he took the oath of office. The indictment of some of closest advisers is just the beginning. His track record suggests that in due course there is no action he will not take, whether illegal or unconstitutional in order to derail his own inevitable impeachment and the indictments that must surely follow the successful investigation of Robert Mueller into his connections with Russia.

However, all of that is a matter for the American people. 

It is also a matter for the American people that Trump is cheating…
