John Baez writes in "The Crackpot Index - A simple method for rating potentially revolutionary contributions to physics":
The most probable date for Good Friday is April 3, 33 AD. Isaac Newton figured that out in 1733.
Easter is that holiday that wanders around in the calendar and which you never quite know when will take place. Some get annoyed by that, but frankly I find it charming. But when did the crucifixion of Jesus really take place?
Questions like these were of much concern to Isaac Newton (1642-1726), surprisingly, since he is best known for gravitation and planetary orbits.
Taking inspiration from Resonaances, who this year offers much more than an April's Fool in his blog
(I am also flattered to see that I am featured there, and with a character of my liking), I am going to offer some predictions for the next run that the LHC is going to start, at the unprecedented energy of 13 TeV, in the next few weeks. The unconventional thing is that I will force the natural scepticism out of my brain, and try to be over-optimistic.The prediction for 2015-2016
Plagiarism is the most sincere form of flattery, they say (or rather, this is said of imitation). In arts - literature, music, painting - it can at times be tolerated, as an artist might want to take inspiration from others, elaborate on an idea, or give it a different twist. In art it is the realization of the idea which matters.
The brakes on your car, the lift in the mechanics shop and
standard construction machinery such as front end loaders, back hoes, and bull dozers all require
hydraulics instrumentation to perform their function. In addition to this, all sorts of industrial
cutters, presses, folders and a substantial amount of manufacturing machinery
depend on hydraulics. Hydraulic
technology is pretty important to our standard of living seeing as how we
depend on it in so many ways to per
Sometimes I think I am really lucky to have grown convinced that the Standard Model will not be broken by LHC results. It gives me peace of mind, detachment, and the opportunity to look at every new result found in disagreement with predictions with the right spirit - the "what's wrong with it ?" attitude that every physicist should have in his or her genes.
When most people think of quantum mechanics they think of Schroedinger's cat, a thought experiment describing a cat inside a closed box, that may be either dead or alive. Only when the classical physics world enters the box do we know. But what is the tipping-point between that cat's life and death, when does quantum behavior give way to classical physics?
Where, on the small scale, is Schroedinger's cat small enough size to be perceived as being both alive and dead at the same time?
A new study in Physical Review Letters has an answer, thanks to a fiber-based nonlinear process that allowed physicists to observe how, and under what conditions, classical physical behavior emerges from the quantum world.
Spring is finally in, and with it the great expectations for a new run of the Large Hadron Collider, which will restart in a month or so with a 62.5% increase in center of mass energy of the proton-proton collisions it produces: 13 TeV. At 13 TeV, the production of a 2-TeV Z' boson, say, would not be so terribly rare, making a signal soon visible in the data that ATLAS and CMS are eager to collect.
It is often claimed that the Ancient Greeks were the first to identify objects that have no size, yet are able to build up the world around us through their interactions.
And as we are able to observe the world in tinier and tinier detail through microscopes of increasing power, it is natural to wonder what these objects are made of.
We believe we have found some of these objects: subatomic particles, or fundamental particles, which having no size can have no substructure. We are now seeking to explain the properties of these particles and working to show how these can be used to explain the contents of the universe.
