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.

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.

There are two ski jumping hills in the Vancouver’s Whistler Olympic Park – Large Hill (LH HS140/K125) and Normal Hill (NH HS106/K95). Technical data and the hill records (given in meters and feet) are available in the tables below.

HillSize (HS) – distance between take-off and landing field where the gradient is equal to 32.5° (see: L-point on the image below)
K-point (calculation line or calculation point) – Skiers are awarded 60 points if they land on the K Line. Skiers not landing on the K Line receive or lose points for every metre (3 ft) they miss the mark by, depending on if they surpass it or fall short, respectively. The value of a meter is determined from the size of the hill.
How K-point and HillSize are calculated, see the image below

It should be obvious that the maximum and average speed in downhill skiing strongly depends on the course racer runs on. On a typical FIS-approved, international-level course racers can run about 130 km/h (80mph) but some courses can be faster. For example, in certain sections of “Streif” course in Kitzbühel, Austria racers can run up to 140 kilometers per hour (87 miles per hour) (Course Start at 1.665m/5462.6ft, finish 805m/2641.08ft, vertical drop 860m/2821.52ft, length 3.312m/10866.14ft, average gradient 27%, maximum gradient 85%, minimum gradient 2%)
Right from the start, racers require a great deal of courage and self-confidence to fully charge the course, launching off to jumps of 50 m to 80 m at the sharp edge into Mausefalle. The Compression following Mausefalle has proved fatal to many a favorite in his struggle to resist the tremendous forces acting on him. (Source: hahnenkamm.com)
Vancouver 2010 downhill men will run February 13th, 2010 on Dave Murray downhill track in Whistler Creek (length 3158m, vertical drop 853m, maximum gradient 47%, average gradient 28% Source:scribd.com )
Speed skiing
Speed skiing is the sport of skiing downhill in a straight line as quickly as possible. It is one of the fastest non-motorized sports on land … The current world record is 251.4 km/h (156 mph), held by Simone Origone. Speed skiers regularly exceed 200 km/h (125 mph), which is even faster than the terminal velocity of a free-falling skydiver; about 193 km/h (120 mph) in the belly-to-earth position
Speed skiing official world records
Men: Simone Origone, Italy – 251.4 km/h (156.2 mph), April 2006 Les Arcs, France
Women: Sanna Tidstrand, Sweden – 242.59 km/h (150.74 mph), April 2006 Les Arcs, France

The table allows you to fast and easily convert most common human heights between values given in feet and inches, inches and centimeters. There is no column for hight given in meters because conversion from centimeters to meters is extremely easy (1m is equal to 100cm. To divide number of centimeters by 100, move the decimal point two places to the right, after that value preceding the decimal point will refer to number of meters and two digits after decimal point will refer to number of centimeters. Example: 162.56cm is equal to 1.6256m is equal to a little more then 1 meter and 62cm).
The table lists only most common human heights (more then 95% of adult human population should meet the criteria: higher then 5 inches and shorter then 7ft 2in) but there are some interesting exceptions – the tallest and the shortest. (To make other conversions try height converter)
Tallest People
At 2.57 m (8 ft 5 in), Leonid Stadnyk, of Zhytomyr Oblast, Ukraine, is believed to be the world’s tallest living man, although his height is disputed because of his refusal to be measured. The current proven tallest man is Sultan Kosen of Turkey who stands at 2.47 m (8 ft 1 in), overtaking previous world record holder Bao Xishun of Inner Mongolia, China at 2.36 m (7 ft 9 in) (interestingly, He Pingping, the shortest man in the world, is also from Inner Mongolia). The tallest man in modern history was Robert Pershing Wadlow from Illinois in the United States, who was born in 1918 and stood 2.72 m (8 ft 11 in) at the time of his death in 1940. Until her death in 2008, Sandy Allen was the tallest woman in the world at 2.32 m (7 ft 7+1⁄2 in). Currently Yao Defen of China is claimed to be the tallest woman in the world at 2.33 m (7 ft 7+1⁄2 in), but this is not confirmed by the Guiness Book of World Records.

Shortest Men
Khagendra Thapa Magar from Nepal stands at only 22 inches (56 cm) tall according to Guinness World Records.
Gul Mohammed – Shortest man ever verified, measuring only 22.4 inches (57 cm), according to Guinness World Records.
Younis Edwan – Shortest man claimant, is said to be 25 inches (64 cm) tall.
He Pingping – Shortest man currently living (mobile) at 74 centimetres (29 in), possibly the shortest man in the People’s Republic of China.
Lin Yu-chih – Shortest man currently living (immobile) at 67.5 centimetres (26.6 in), according to Guinness World Records

Shortest Women
Pauline Musters – at 23 inches (58 cm) tall, recognised by the Guinness Book of Records as the shortest woman ever recorded.
Madge Bester – 65 cm in 1998
Lucia Zarate – Smallest woman claimant and the earliest studied example of microcephalic osteodysplastic primordial dwarfism type
Jyoti Amge – 23-and-a-half inches tall, weighing 12 pounds.

Are you tired of units conversion? …. changing meters to yards, fahrenheits to celsius, meters per seconds to feet per minutes, calculating speed could be a little boring So, let’s get a break!
We made simple javascript based, pong-like online game (do you remember first, hm … hard to say computer … maybe ‘an electronic game’. It seems to be an ancient game, right?). Rules are simple. Don’t allow the ball to hit the right side wall. It is called PONG PING because … why not? … it resembles a table tennis called PING PONG and the name seems to us … hm, … funny? Never mind, enjoy

PS. Don’t worry, we’ll get back to units of measurment soon
