Recording of the week: Rock Island Line

This week's selection comes from Andy Linehan, Curator of Popular Music Recordings.

‘Rock Island Line’ was the hit single that sparked the Skiffle craze amongst British youth in the late 1950s. Skiffle was a pared-down mixture of jazz, blues and folk influences played on a mixture of tea-chest bass, washboard, guitars and banjo. Its simplicity made it accessible and appealing to the new generation of British teenagers. Lonnie Donegan’s recording of ‘Rock Island line’, an American folk song popularised by Leadbelly, inspired a host of British musicians including Cliff Richard, Jimmy Page, John Lennon and Paul McCartney to form their own groups and laid the foundation for decades of successful British Rock and Pop music.

The Skiffle phenomenon is the subject of the forthcoming book 'Roots, Radicals and Rockers: how Skiffle changed the world' by musician Billy Bragg.

Space telescope to observe ‘big eaters’ in universe

China’s new space telescope to be launched soon will probe many mysteries of the universe, including the belching “big eaters” — active galactic nuclei at the most remote edges of the universe.

Scientists have discovered that almost every galaxy has a supermassive black hole with a mass several million to several billion times that of the Sun at its center. With their mighty gravitational attraction, the supermassive black holes engulf the surrounding gas and dust.

When a black hole swallows too much, the excess matter is converted into two jet-flows perpendicular to the accretion disk of the black hole, which is like a glutton with a bloated belly belching.

The jet-flows and accretion disk of the supermassive black hole generate X-ray radiation strong enough to travel billions of light years. These galaxies have very bright nuclei — so bright the central region can be more luminous than the remaining galaxy. Scientists call them active galactic nuclei.

The Hard X-ray Modulation Telescope (HXMT), developed by Chinese scientists, will observe some active galactic nuclei. “Since the active galactic nuclei are very far from the Earth, our telescope can only detect the brightest ones,” says Zhang Shuangnan, lead scientist of HXMT and director of the Key Laboratory of Particle Astrophysics at the Chinese Academy of Sciences (CAS).

The big eaters are full of mysteries. Scientists have found the double jet phenomenon is very common in galaxies with active galactic nuclei, but they don’t understand why supermassive black holes cannot engulf all the matter falling into them.

Supermassive black holes are very different from black holes of stellar mass, which are formed when very massive stars collapse at the end of their life cycles. Scientists are still not clear how supermassive black holes are formed and grow, which is a key to understanding the evolution of galaxies.

HXMT’s observation is expected to help scientists see the core region close to the event horizon of supermassive black holes at the center of active galaxies and gather information about the extremely strong gravitational fields, Zhang says.

Cybersecurity law starts for better personal info protection

China’s Cybersecurity Law will take effect on June 1, banning online service providers from collecting and selling users’ personal information.

The internet service providers cannot collect user information that is irrelevant to the services, and they should handle such information in line with laws and agreements, according to the new law that was adopted by China’s top legislature in November last year.

Users now have rights to ask service providers to delete their information if such information is abused.

Cybersecurity management staff must also protect information obtained, and are banned from leaking or selling the information, including privacy and commercial secrets.

Those who violate the provisions and infringe on personal information will face hefty fines.

The law also made it clear that no one can use the internet to conduct fraud or sell prohibited goods.

Several other regulations will come into force on June 1.

A regulation on online news requires individuals and groups to get government permission before releasing news on instant messaging apps or social websites.

Civilian drones weighing more than 250 grams must be registered under real names to improve civil aviation safety.

An amended regulation on farming pesticide bans the use of highly toxic pesticides on edible agricultural products and strictly limits the use of pesticide.

Defence Minister Arun Jaitley dedicates Aeronautical Test range to The Nation

The Defence Minister Shri Arun Jaitley today inaugurated the newly built Aeronautical Test Range (ATR) of the Defence Research & Development Organisation (DRDO) at Chitradurga in Karnataka. Addressing a gathering of eminent scientists and other defence personnel on the occasion, the Defence Minister said facilities such as the ATR will help in creating conditions for research, which will in turn develop the type of human resource in the country required in the field of aeronautical testing.

Why more nationalisation is a bad idea

image_pdfimage_print

I was asked to explain why I do not favour nationalising the railways, the Post Office, the water industry and the energy utilities yesterday on the radio.It was a trip down Memory Lane to the arguments of the last century, when Labour made the case for continued or more nationalisation despite all the evidence of the damage their policies did.

Nationalisation was the best way to lose more employees their jobs, to charge customers more, and to sting the taxpayer to pay the losses. The coal industry lost most of its workers when nationalised. The workforce of 704,000 of the newly nationalised industry in the late 1940s had fallen to as few as 235,000 by the time of the election of the Margaret Thatcher government. Despite all the closures of mines and sackings, the losses mounted to be paid by taxpayers.

The railways under public ownership experienced continuous decline. In 1950 they employed 606,000 staff and had 19,471 miles of operating track. By 1976 then under a Labour government staff numbers had more than halved to 244,000 and route miles had fallen to 11,189. The market share of the railways halved, and the number of stations fell by two thirds. The nationalised steel industry too, under Labour and Conservative governments, spent most of its time discussing how to curb the losses by cutting back on capacity and jobs.

Labour say they wish to renationalise the railways. The truth is the main cost and the main assets of the railway are already nationalised. The tracks, signals and stations are owned by Network Rail, itself wholly owned by taxpayers and financed by the Treasury. Many of the delays which affect rail services are the result of signalling failures or other Network Rail caused events. It is Network Rail’s job to expand capacity by improving signalling so more trains per hour can run on the railway.

I was asked why we did not buy shares in water companies whilst keeping in place current private sector management so we participate in the profits. I replied that we have other more important priorities for public sending. In the past government ownership of industries has not brought dividends and profits overall, but losses and the need for more subsidised capital.

The main way to improve service quality and bring down prices of utilities is to increase competition. That is what we need to do in some cases, as there is clearly room for improvement. What we do not want to do is to go back to a world where customers, employees and taxpayers all get a bad deal, which was the typical experience of our nationalised industries.

Labour’s big nationalisation programme has not been costed and is unaffordable. From past experience it would lead to worse service and huge bills for taxpayers.
