The Sunway TaihuLight is the fastest supercomputer as of November 2017 ranked number one in the Top500 list. It has a speed of 93 petaflops on LINPACK benchmark rating (1 petaflop=10 raised by 15) . FLOP stands for “floating point per second”.
It is in China and was designed by National Research Center of Parallel Computer Engineering And Technology. It is located at the National Supercomputing Centre in Wuxi in Jiangsu province of China.
China beat the US in global rankings done by website Top500 which tracks the supercomputers. Benchmark tests are done by experts from Germany and US.
Some 202 supercomputers are in China as compared to 143 in US. China leads not only in numbers but aggregate computing power.
List of top 5 is as under
- Sunway TaihuLight……. China
- Tianhe-2 (Milky way-2)….. China
- Piz Daint… Switzerland
- Gyoukou…… Japan
The fastest supercomputer is being used in climate modelling and science research.
With 1 barrel of oil with 32 API or 7.21pounds per gallon(specific gravity=0.864) , this much can be made and done.
1. Wax for 170 birthday candles or for making 27 crayons
2. Lubricants to make 1 quart of motor oil
3. About 4 pounds of charcoal briquettes
4. Gasoline to drive a medium sized motor car (7.2 km/litre) for 451 kilometres
5. Distillate to drive a large truck (2 km/liter) 64 kms. If jet fuel fraction is included then 80.5 kms.
6. Asphalt to make 3.785 liter of tar for roof patching
7. 70 KW hours of electricity at a power plant
8. Liquified gases such as propane to fill 12 small (14.1 ounces) cylinders.
After all this, there would be enough petrochemical left in the same barrel for making
750 pocket combs
65 plastic drinking cups
11 telephone housing
39 polyester shirts
65 plastic dustpans
23 hula hoops
135 four inches rubber balls
195 one-cup measuring cups

Discovered: Date unknown in India
The name means” Mountain of light” in Persian language. Once known as the largest diamond in the world. It is believed to have originated in Andhra together with its double called”Darya-ye-Noor” meaning “Sea of light”.
It was originally owned by Kakatiya Dynasty which installed it in a temple as the EYE of the goddess. It has had a troubled history having been stolen, confiscated or taken over as war loot by various invaders.
Presently it is a part of the Crown of Queen Elizabeth having been confiscated from its owners in 1850 by imperial powers.
Western powers have monopolized the nuclear power and weapons. Russia and US hold 92% of the resources. Treaties like CTBT discriminate against the rest of the countries who want to use nuclear resources even for peaceful purposes. India has not signed this treaty. Supply of nuclear materials is controlled by Nuclear Supplies Group (NSG) which is largely controlled by US and Russia and puts discriminatory conditions on developing nations.This is why they are bitterly opposing nuclear tests by North Korea who is not toeing to their line.
Here are statistics
No. of nuclear tests:
USSR Russia: 715
North Korea: 6
There is no doubt that USA laps up the talent from all over the world. US leads the tally of Nobel prize winners which were introduced in 1901 and Economics prize introduced in 1968. Since then 585 Nobel prizes have been awarded to 922 winners out of which only 49 are women.
Youngest and oldest
Youngest person to receive the Nobel is Malala Yousafzai who received it at the age of 17 years in 2014. Although she belongs to Pakistan, her country may hardly be happy over her winning it. Oldest Nobel laureate is Leonid Hurwicz of US who received the Nobel in 2004 for economics at the age of 90 years.
Countries at the top of list.
Major areas of research leading to Nobel
In physics is particle physics and in chemistry is biochemistry. Research in genetics most hot topic and in economics it is micro economics.

HOW THE WORLD CAME TO KNOW THAT TSANGPO AND BRAHMAPUTRA ARE ONE AND THE SAME RIVER?
It is thanks to the person in the picture. His name was Kinthup, a tailor by profession.
British officers sent him on a very dangerous mission because despite being illiterate he had amazing graphic memory.
As we know now Brahmaputra which originates from Tibet and flows East and suddenly enters very deep gorges to loose height and enter North East India. It is known as Tsangpo in Tibet . But during 1880, it’s path was not mapped. Some people even doubted that these are two different rivers.
Tibet was then a closed country and not under British. When the sent Kinthup through Sikkim in 1880 secretly to go as far as possible along the river. Plan was that Kinthup would throw wooden logs (specially marked) into the river in Tibet and British troops were stationed in India. If it was the same river, they soldiers will definitely retrieve them.
He remained for 4 years on his mission facing lots of hardships, arrests, slavery , sleeping on treetops. Returned back in 1884.
