Calculation of Easter

The Easter is a holiday so-called mobile: its date varies from year to year because it is correlated with the lunar cycle . The Passover and Easter Christians follow different rules of calculation and therefore are almost never the same day. Within Christianity then there are two different rules depending on whether you use the Gregorian calendar (Catholics and Protestants) or the Julian (Orthodox). These two rules in a few years give the same date (and therefore all Christians celebrate Easter on the same day, and the case this year - ed), different dates in other years.

follows roughly the Christian Easter and Jewish, but differs from that for two reasons: the first is that it is always celebrated on Sunday, the day of resurrection of Jesus, the second is that it is not used for calculating the Jewish calendar.

The rule fixing the date of Easter was established in 325 by the Christian Council of Nicaea: Easter falls on the Sunday following the first full moon after the spring equinox (March 21).

Consequently, it is always included in the period from March 22 to April 25. Assuming that in fact the first full moon of spring occurs on the day of ' same equinox (March 21) and is a Saturday, then Easter will have the very next day, or March 22. If, however, the full moon occurs on March 20, not until the next full moon (29 days), then getting to 18 April. Finally, if this day was a Sunday, then it will be necessary to fix the date of Easter Sunday even later, namely April 25.

Happy Easter to all our readers!

... and remember "You can not see Easter or after San Marco (25 / 4), nor before St. Benedict (21 / 3).

PS: next year Easter falls on April 24 ...

astronomer Profession: stories of women scientists

Each section of the exhibition opens with a video interview with people whose ideas have revolutionized-marked-influenced throughout history. All these characters (from Aristotle to the Jedi knight, through Newton, Hubble and Bell) are facing the same questions on the conception of the universe, and it is interesting to hear and understand the answers to these questions have changed over the centuries.

Among these players there is just too Jocelyn Bell, who discovered the first pulsar astrophysics, and yet he did not see such an important scientific contribution recognized with the Nobel Prize, awarded instead to his teacher.
addition to the pulsar, this interview is therefore useful to discuss the difficulties, this unfortunately also in the scientific community to achieve full equality of opportunity between men and women.

Here is a blog that is a good idea to "enter" in the world of many astronomers, thanks to their own stories of life experiences and work collected during the International Year of Astronomy:

How Much Is A Shiny Charizard Worth

As Matthew pointed out in previous posts, today all ' LHC has taken up a stone to important developments in physics in the coming years. It was 13:06
in Geneva when the two beams collided at high energy and huge detectors heard the faint signals originated from the myriad of particles resulting from the collision.

At the same moment, another much smaller detector and raw commenced operations also showing traces of ephemeral particles well beyond the human senses. Absolutely
by-case basis in fact, during my lunch break, I helped Francis to test our new cloud chamber that will soon be exhibited to show the public the cosmic rays

:-) I would say that it works very well, every second showing numerous contrails very mixed, with many soft and straight, others with sudden detours, others very clear ee large. a real show!

I intend soon to post a short video. For now, only a frame a bit 'confused;)

particle detectors at CERN in Geneva, a stone's throw from Big Bang

process almost recreated in the laboratory

The largest particle accelerator world Cern in Geneva has reached the maximum almost never touched able to collide two beams of protons to create conditions similar to those of Big Bang which gave birth to the universe. The Large Hadron Collider , which runs for 27 km under the border between Switzerland and France, has generated seven trillion of elettrovolt. The LHC, which opened in 2008, he was stopped for 48 hours after a fault.

And so, after two failures that occurred in the early hours of the day, the protons at the time of the clash have traveled at a speed close to that of light. Now researchers, who will analyze the data collected, turn off the LHC to switch back on after maintenance work and expansion that will last almost a year. At that point the power will be doubled to 14 TeV, a level that comes close to those more experienced in the first instants of the Universe.

The Large Hadron Collider is the largest particle accelerator ever built and has so far had a rather unfortunate. Opened September 10, 2008, just 36 hours after it was shut down for failure due to a faulty electrical connection between two of the superconducting magnets of the machine. In the subsequent repair work has been accommodated another 53 defective magnets.

With the LHC scientists (among whom there are many Italians that the latter rappsentano lenders and the second scientific community at CERN) have the objective of verifying the existence of smaller particles and elusive, like the famous Higgs boson , dubbed the "God particle", and understand the nature of matter and of 'energy "dark" that are respectively 23% and 72% of the universe. The visible matter and energy account for only 5% of the total universe.
