Neutrino Speed

Friday, September 23rd, 2011

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”

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.

Downhill skiing speed

Monday, February 8th, 2010

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:

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% )

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

Speed Calculator Online

Wednesday, January 6th, 2010

Today Speed Calculator Online has been launched. This is 3 in 1 calculator. The tool allows you to calculate average speed having traveled distance and time or calculate traveled distance having speed and time or you can fast and easy find traveling time having average speed and traveled distance.

Like all of ours tools (calculator and converters) you will get the answer very fast – the answer is displayed as you type – no button ‘Compute’, ‘Ok’ or ‘Calculate’ is needed.

You can, of course, input your data in different unit of measure. Distance in inches to leagues (US and Imperial system of measurement), millimeters to kilometers (metric system) or even in nautical system (cables, nautical miles and nautical leagues). Speed is displayed or can be inputed in inches, feet, yards, miles, leagues, millimeters, centimeters, decimeters, meters kilometers, nautical miles, cables, nautical leagues per second/minute/hour.


Samantha Stosur serve speed

Friday, November 6th, 2009

During the WTA Tour on Bali Samatha Stosur unofficialy broke Venus Williams serve speed record. Her fastest serve was 208kph (129.2452mph), so it looks like she set new women’s record. Current official record held by V.Williams is 207.6kph (128.9967mph). The WTA said Stosur struck was pending verification.

PS. Despite her service struck Samatha Stosur lost her match with Maria Jose Martinez Sanchez 6:7, 5:7.

4x100m relay 37.32

Saturday, August 22nd, 2009

This time Usain Bolt with his team did not break world record. The Jamaican team (Steve Mullings, Michael Frater, Usain Bolt, Asafa Powell) ran 4×100 m men’s sprint relay in 37.32 s.
Current world record was set 37.10 seconds by the Jamaican (Nesta Carter, Michael Frater, Usain Bolt, Asafa Powell) team during Olympic Games Beijing 2008.

When and what time 4×100 m final men’s in Berlin 2009
The final 4×100 m men’s race is scheduled for Saturday, 22 August 2009 20:50 (Berlin local time – CEST) [11:50 AM PDT, 2:50 PM EDT]

Today (22 Aug 2009) Usain Bolt will run again. This time, together with other jamaican sprinters, in 4×100 meters relay. Is the jamaican team able to break another world record? Current World Record in 4×100 relay sprint was set by Jamaican team (Nesta Carter, Michael Frater, Usain Bolt, Asafa Powell) at Olympic Games Beijing 2008. They ran the relay in 37.10 s. World Championships Record in 4×100 m relay stands at 37.38 as set by American Team (Darvis Patton, Wallace Spearmon, Tyson Gay, LeRoy Dixon) in 2007.

Average Speed in 4×100 m sprint relay men’s:
World Record 37.10 seconds. Speed = 400m/37.10s = 10.7817 m/s (click to convert speed)

Usain Bolt 19.19

Thursday, August 20th, 2009

He did it again. Next final race and next world record. August 20th, 2009 Usain Bolt ran 200 m in 19.19 at the 12th IAAF World Championships in Athletics Berlin 2009. He is genius and amazing sprinter.

I think, after his 100 m final race in Berlin when Bolt broke his own record, everybody was sure that he is able to break the record in 200 m race. The question was: how fast he can run? Now, we got the answer. Usain Bolt ran 200 m in 19.19 and his average speed on this distance was 10.4221 m/s. (Click on the link to get conversion into other units of measurement e.g mph, kmh, yd/s)

Berlin 2009 200 m men’s final

Tuesday, August 18th, 2009
When and what time does 200 m final men’s in Berlin 2009
The final 200 m men’s race is scheduled for Thursday, 20 August 2009 20:35 (Berlin local time – CEST) [11:35 AM PDT, 2:35 PM EDT]

Usain Bolt’s amazing 100m world record shows that he is the fastest man in the world ever. Is he able to break the 200 m world record? Let’s try to predict Bolt’s time in 200m final race in Berlin 2009.

Bolt’s speed and time prediction during the final 200 m race in Berlin 2009
Usain’s Bolt average speed in the winning 100m men’s race was: 100m/9.58s = 10.43841 m/s (23.3501mph). So, if he can run 200 meters with this speed, he can get the time 200m/10.43841m/s = 19.16s !!! (his current world record is 19.30s) but, as we look at previous world records (see table below), average speed on 200m distance is faster then during 100m race, so we can expect even better result.

Beijing 2008
100m 9.69s 10.3199m/s v200/v100=1.00415 Usain Bolt 16 Aug 2008
200m 19.30s 10.3627m/s Usain Bolt 20 Aug 2008
100m 9.72s 10.2881m/s v200/v100=1.006211 Usain Bolt 31 May 2008 New York
200m 19.32s 10.3520m/s Michael Johnson 1 Aug 1996 Atlanta

, Previous athletic records

As we can see, 200m distance speed is about 0.4-0.6% faster then on 100m distance. So, expected Bolt’s speed could vary beetween 10.43 m/s and 10.50 m/s. It gives us amazing times between 19.175s and 19.048s. I, personaly, think that Usain Bolt is able to run 200 m in Berlin in about 19.15s
