According to the Albert Einstein theory, speed of light is the Universe’s ultimate speed limit, but an experiment that have been carrying by Dr Ereditato and his team for last three years suggest neutrinos can travel faster then light.
This puzzling result from Cern has to be investigated for possible errors. As Dr Ereditato says:
“We are not claiming things, we want just to be helped by the community in understanding our crazy result –
because it is crazy”
More about experiment (OPERA detector, measurement methods, data selection, conclusions) you can read on
“Measurement of the neutrino velocity with the OPERA detector in the CNGS beam”
http://arxiv.org/ftp/arxiv/papers/1109/1109.4897.pdf
The OPERA neutrino experiment at the underground Gran Sasso Laboratory has measured the
velocity of neutrinos from the CERN CNGS beam over a baseline of about 730 km with much higher
accuracy than previous studies conducted with accelerator neutrinos. The measurement is based on highstatistics
data taken by OPERA in the years 2009, 2010 and 2011. Dedicated upgrades of the CNGS
timing system and of the OPERA detector, as well as a high precision geodesy campaign for the
measurement of the neutrino baseline, allowed reaching comparable systematic and statistical accuracies.
An early arrival time of CNGS muon neutrinos with respect to the one computed assuming the speed of
light in vacuum of (60.7 ± 6.9 (stat.) ± 7.4 (sys.)) ns was measured. This anomaly corresponds to a relative
difference of the muon neutrino velocity with respect to the speed of light (v-c)/c = (2.48 ± 0.28 (stat.) ±
0.30 (sys.)) ×10-5.

As I wrote before, i’m working on a project related to current world time,
sunrise and sunset time over the world, etc.
Because of 13th World Championships in Athletics currently being held in Daegu, South Korea,
many of you could be interested in checking current time in Daegu. So, here it is:
Current Time in Daegu, Korea
More Info:
Daegu location: 35° 52′ 13″ N, 128° 35′ 27″ E
UTC offset: UTC+9:00

As you can read in the previous post I work on new part of the site. New subdomain deals with everything that is related to world time and timezones. The main idea is to made a portal where you can find current local time, sunrise, sunset time, length of the day and other information related to rotation of the Earth in any place around the world.
At the moment you can use only a part of the new subdomain, where you can find sunrise, sunset and sun transit time in over 200,000 places around the world. For example, you can find out when the sun comes up in San Francisco or when the sun goes down in Denver, CO, sunrise in Barcelona, Spain. You can also find out sunrise and sunset, day length info for small towns in the US, e.g. day length in Key Largo, FL, today’s sunrise in Princeton, NJ or around the world e.g. sunset in Lloret de Mar, Spain, sunrise in Goa.
I hope that new features and information will be available soon.

After a while (hmm, … a while?  ) of doing nothing on unitarium.com, I,m back with the site updates. I cleaned up the mail box and installed spam box filters. Over 11,500 messages are recognized as spam. Unfortunately, some valuable mails and comments could be removed, so I lost possibility to answer them – sorry, but the good news is … thanks to new spam filters I will be able to find important mails and comments and answer or approve them immediately (I hope so).
Another good news is that I work on new part of the unitarium site. The new part deals with ‘world time‘. I want to make a world time clock that shows current local time over the world. So far, a part of the project is available. It shows sunrise, sunsets, length of the daytime and other infos (including local time) in over 300,000 cities in all countries. Very early version of the site is available here: Sunrise, Sunset And Length of Daytime. For example, you can easily check today’s sunrise time in Chicago, tomorrow’s length of the day in New York, or even little towns e.g. sunrise in Parlin, NJ, sunset in Angels Camp, CA today. Of course, you can check locations outside of US, even on the other side of the world e.g. sunrise in Beijing, China today, day length in Hawaii, sunset time in Rio de Janeiro today.
Have fun, I’m going back to work, see you soon.

Although we have more then 2 months to the end of the year, we just launched on our site online calendar for 2011 with US Federal Holidays marked on it. There are two versions of the calendar, online version (link above) and printable version of the calendar for 2011
. Enjoy!.
The printable version is configurable, it allows you to configure size e.g. pocket, medium, letter and calendar font and then print the calendar with or without the background.
There’s still plenty of time, but … HAPPY NEW YEAR 2011!!!

This is a humorous post before last matches but if you are interested in real visual analysis of chances for Chile, Spain, Switzerland and Honduras to go out of the group stage of 2010 FIFA World Cup, follow this link: Group H, Spain-Chile, Switzerland-Honduras analisys of chances to qualify
Take a look at the image on the left. It is a visualisation of chances to qualify to the round of 16 out of group H. It resembles a dog, doesn’t it?
Is this an omen for Spain, Chile, Honduras or Switzerland? 😉 Good or bad? Who will win?
Do any of today playing countries have a dog in their national emblems or any other signs?
Is this Swiss Mountain Dog, maybe? And if so, is this good or bad omen for Switzerland? Will Switzerland win their match and mayby Honduras, Chile or Spain will qualify? We will see in a few hours. Anyway, good luck for them all.

Today next World Cup matches: Italy vs. Slovakia and Paraguay vs. New Zealand. What results. What results Italy need to qualify? What are the chances for New Zealand to qualify? What are the chances for Slovakia or Paraguay? Look at the below image. ( More visual analysis are available here: World Cup Analysis )
Each square on the image represents results of both matches. Colors tell us who will be qualified. As you can see Italy (white and blue) need to win against Slovakia to be sure to be qualified. What about a drawn match Italy vs. Slovakia? If New Zealand win (black squares bottom) Italy are out of the next round (New Zealand and Paraguay qualify). If Paraguay win, Italy are in (and Paraguay). If Paraguay against New Zealand ends with a draw, there are three possible scenarios. 1) Paraguay (and New Zealand) scores more goals then Italy => Paraguay and New Zealand qualify (black squares in the middle). 2) Italy scores more goals then Paraguay => Italy and Paraguay quallify. (white squares below black diamonds). 3) Italy Slovakia 0:0, 1:1, 2:2, 3:3, …. and Paraguay New Zealand 0:0, 1:1, 2:2, 3:3, … respctively => drawing of lots will be needed because Italy and New Zealand have same number of points and goals for and against and the match Italy against New Zealand is drawn (1:1)
Slovakia need to win against Italy to qualify (red squares) and Paraguay must not lose more then … depends on Italy Slovakia result (gray squares)
Paraguay if they win or draw, they are in round of 16. If they lose, there are some chances to qualify (black squares)
New Zealand if they win, they are in. If they lose they are out. If they draw there are some chances – black squares and diamods in the middle of the image (see Italy’s above)

The below table shows situation in FIFA 2010 World Cup’s Group C before last matches of the group stage. Each square on the drawing represents different result of last both matches in group C (Slovenia – England and Algeria – USA). Colors on the drawing show us who will go out the group and will be qualified to round of 16.
More similar visualisation can be found on: FIFA 2010 World Cup Groups
White and blue squares on the drawing tell us that USA will be qualified. As you can see, if the USA team wins against Algeria at least 1:0, it will be qualified to the next round (England vs Slovenia does not matter in this case). If USA draw to Algeria and England do not win to Slovakia, USA will be qualified in most cases, but there are some results that promotes England insted of USA (black squares in the middle).
Drawing of lots
There are also three pairs of interesting results (USA – Algeria 2:2,1:1,0:0 and England – Slovenia 1:1,2:2,3:3) marked by the black diamonds. In this case both teams have same number of points (3), same number of goals (3,4 or 5 depending on the result) and same number of goals scored in match between USA and England. Due to the terms of FIFA World Cup, drawing of lots will be needed to find the winner.
When does FIFA draw of lots to find the winner.
Below are the FIFA’s criteria that allows to find the winner of the group stage:
1.greatest number of points in all group matches;
2.goal difference in all group matches;
3.greatest number of goals scored in all group matches;
4.greatest number of points in matches between tied teams;
5.goal difference in matches between tied teams;
6.greatest number of goals scored in matches between tied teams;
7.drawing of lots by the FIFA Organising Committee.

Look at the below visualisation of the situation in FIFA 2010 World Cup’s Group C before last phase of the group stage. Each square of the drawing represents different result of the both last matches in group C (England vs. Slovenia and USA vs. Algeria) and colors on the drawing tell us who will be qualified to the next round.
Below drawing of visual analysis comes from : FIFA 2010 Group C Analysis
Black, blue and gray squares indicate that England will be qualified. As you can see, if they win against Slovenia a least 1:0, they will be qualified to the next round. There are also some cases in which England will advance, if they draw the match (black squares in the middle of the drawing). There are also three pairs of interesting results (USA – Algeria 2:2,1:1,0:0 and England – Slovenia 1:1,2:2,3:3) marked by the black diamonds. In this case both teams have same number of points (3), same number of goals (3,4 or 5 depending on the result) and same number of goals scored in match between USA and England. Due to the terms of FIFA World Cup, drawing of lots will be needed to find the winner.
