Alexander Graham Bell recordings played from 1880s


Alexander Graham Bell recordings played from 1880s — Alexander Graham Bell foresaw many things, including that people could someday talk over a telephone. Yet the inventor certainly never could have anticipated that his audio-recording experiments in a Washington, D.C., lab could be recovered 130 years later and played for a gathering of scientists, curators and journalists.

"To be or not to be..." a man's voice can be heard saying in one recording as it was played on a computer at the Library of Congress on Tuesday. The speaker from the 1880s recites a portion of Hamlet's Soliloquy as a green wax disc crackles to life from computer speakers.

The early audio recordings — which revealed recitations of Shakespeare, numbers and other familiar lines — had been packed away and deemed obsolete at the Smithsonian Institution for more than a century. But new technology has allowed them to be recovered and played.

The technology reads the sound from tiny grooves with light and a 3D camera.

The recordings offer a glimpse into the dawn of the information age, when inventors were scrambling to make new discoveries and secure patents for the first telephones and phonographs, even early fiber optics.

A second recording, on a copper negative disc, played back Tuesday reveals a trill of the tongue and someone reciting the numbers 1-2-3-4-5-6.

A third recording catches perhaps the first sound of disappointment as Bell's recording device seemed to hit a technical glitch.

"Mary had a little lamb and its fleece was white as snow," a voice says. "Everywhere that Mary went — Oh no!"

On Nov. 17, 1884, Bell's lab recorded the word "barometer" several times on a glass disc with a beam of light. It and about 200 other experimental records were packed up and given to the Smithsonian, seemingly never to be played again.

The recordings date back to the 1880s. Bell had moved from Boston to Washington after obtaining a patent on March 10, 1876 for his invention of the telephone, which occurred when his employee Thomas Watson heard him shouting over a wire in the next room. He joined a growing group of scientists who made the nation's capital a hotbed for innovations.

Bell partnered with his cousin Chichester Bell and Charles Sumner Tainter to create Volta Laboratory Associates in Washington in the early 1880s.

During this time, Bell sent the first wireless telephone message on a beam of light from the roof of a downtown Washington building — a forerunner to modern fiber optics. He and other inventors also were scrambling to record sound on anything they could find, including glass, rubber and metal. One early sound record looks like a smashed soup can.

Inventors at the time were in intense competition. Bell, Emile Berliner and Thomas Edison, who invented the phonograph to record sound on tin foil in 1877, each left objects and documentation with the Smithsonian to help prove their innovations were first.

Bell went so far as to seal some devices in tin boxes for safe keeping at the Smithsonian. Edison's earliest recordings are thought to be lost.

"This stuff makes the hair stand up on the back of my neck," said Curator Carlene Stephens of the National Museum of American History before Bell's recordings were played Tuesday. "It's the past speaking directly to us in a way we haven't heard before."

The museum's collection of about 400 of the earliest audio recordings, including 200 from Bell's lab, will likely become a key resource for new research on communications and early technology now that they can be played back, Stephens said.

"These materials have been in a cupboard and virtually unknown for decades," she said. "The collection has been silent."

The Library of Congress partnered with the Lawrence Berkeley National Laboratory at the University of California, Berkeley, to offer the first listen of these early recordings Tuesday. Scientists have spent the past 10 years and about $1 million to develop the technology to create high-resolution digital scans of the sound discs.

This year, scholars from the Library of Congress, the Berkeley Lab and the Smithsonian gathered in a new preservation lab at the Library of Congress and recovered sound from those early Bell recordings. A $600,000 three-year grant from the U.S. Institute of Museum and Library Sciences funded the pilot project, and the Smithsonian hopes to continue the work if future grants can be secured.

Advances in computer technology made it possible to play back the recordings, said Carl Haber, a senior scientist at the Berkeley Lab. He noted that 10 years ago specialists would have struggled with computer speeds and storage issues. The digital images that now can be processed into sound within minutes would have taken days to process a decade ago.

Many of the recordings are fragile, and until recently it had not been possible to listen to them without damaging the discs or cylinders.

So far, the sounds of six discs have been successfully recovered through the process, which creates a high-resolution digital map of the disc or cylinder. The map is processed to remove scratches and skips, and software reproduces the audio content to create a standard digital sound file.

Haber said Bell's recordings and others in the fierce competition of the 1880s marked the start of the information age as we know it.

"The whole idea that you could capture the world as it exists" in a recording, he said, "they got that in this period." ( Associated Press )

Get the ‘message’




Get the ‘message’ - Some messaging habits can cause a bad impression. We tell you all about them...


Don't keep it too short:

If you are messaging a girl/boy you want to impress, then don't send messages that may make you uninteresting. Sending 'k' as a reply is absolutely unacceptable. You definitely need to take the effort to add 'o' to make it 'ok', right?


No mass smses please:

If you are trying to ensure that a guy or girl gets to know that you are showering them with attention then don't send them messages like 'What are you up to?' or 'Let's all catch up'. He/she may never bother to reply to your message.


Keep away from your phone:

Yes, we are all addicted to our gadgets, but you have to learn to keep away from them. If you are having coffee with your crush, then don't spend most of your time typing away SMSes. You date may think that you can't really hold an interesting conversation on your own.


Don't be a tease:

If it's rude to leave a conversation half-way, then it's equally rude to cut your SMS conversation mid-way. The person you are texting is bound to be irritated if you are going to stop messaging. If you doze of while messaging late in the night or have to rush for a meeting, then make sure you send a message to clear the air.


Don't be a show off:

Don't be stupid and show everyone at the table the SMS that you've just got from someone else. Showing your friends, the text your boyfriend sends may not be a good idea. Not just because it may make them uncomfortable, but also your boyfriend may not like it either. So, don't show and tell.


Stop the teen speak:

If your boyfriend's still sending you messages like 'TTY L8R' (talk to you later) or C U 2mrw (see you tomorrow), it's time you told him to grow up and start sending messages that don't seem like an exchange between two college kids.


Don't use texting to avoid the bill:

That's just cheap. And you may think you are a smooth operator, but everyone will notice. So don't use this trick when you are out either with a date or your friends. ( indiatimes.com )

Quake-hit Japan nuclear plant faces fresh threat


Quake-hit Japan nuclear plant faces fresh threat – Japan battled to contain a radiation leak at an earthquake-crippled nuclear plant on Sunday, but faced a fresh threat with the failure of the cooling system in a second reactor.

Operator TEPCO said it was preparing to release some steam to relieve pressure in the No.3 reactor at the plant 240 km (150 miles) north of Tokyo -- which would release a small amount of radiation -- following an explosion and leak on Saturday in the facility's No. 1 reactor.

As strong aftershocks continued to shake Japan's main island the desperate search for survivors from Friday massive earthquake and tsunami continued, and the death toll was expected to rise.

Thousands spent another freezing night huddled over heaters in emergency shelters along the northeastern coast, a scene of devastation after the 8.9 magnitude quake sent a 10-meter (33-foot) wave surging through towns and cities.

Kyodo news agency said the number of dead or unaccounted for as a result of the quake and tsunami was expected to exceed 1,800. It also reported there had been no contact with around 10,000 people in one small town, more than half its population.

The government insisted radiation levels were low following Saturday's explosion, saying the blast had not affected the reactor core container, and the International Atomic Energy Agency (IAEA) said it had been told by Japan that levels "have been observed to lessen in recent hours."

But Japan's nuclear safety agency said the number of people exposed to radiation from the Fukushima Daiichi plant could reach 160. Workers in protective clothing were scanning people arriving at evacuation centers for radioactive exposure.

Around 140,000 people had been evacuated from areas near the plant and another nuclear facility nearby, while authorities prepared to distribute iodine to people in the vicinity to protect them from radioactive exposure.

"There is radiation leaking out, and since the possibility (of being exposed) is high, it's quite scary," said Masanori Ono, 17, standing in line on Saturday to be scanned for radiation at an evacuation center in Fukushima prefecture.

Before news of the problem with reactor No. 3, the nuclear safety agency said the plant accident was less serious than both the Three Mile Island accident in 1979 and the 1986 Chernobyl nuclear disaster.

An official at the agency said it has rated the incident a 4 according to the International Nuclear and Radiological Event Scale (INES). Three Mile Island was rated 5 while Chernobyl was rated 7 on the 1 to 7 scale, the official said.

DEVASTATED COASTLINE

Along the northeast coast, rescue workers searched through the rubble of destroyed buildings, cars and boats, looking for survivors in hardest-hit areas such as the city of Sendai, 300 km (180 miles) northeast of Tokyo.

Aerial footage showed buildings, trains and even light aircraft strewn like children's toys after powerful walls of seawater swamped areas around Sendai.

In Iwanuma, not far from Sendai, nurses and doctors were rescued on Saturday after spelling S.O.S. on the rooftop of a partially submerged hospital, one of many desperate scenes. In cities and towns, worried relatives checked information boards on survivors at evacuation centers.

Dazed residents hoarded water and huddled in makeshift shelters in near-freezing temperatures.

"All the shops are closed, this is one of the few still open. I came to buy and stock up on diapers, drinking water and food," Kunio Iwatsuki, 68, told Reuters in Mito city, where residents queued outside a damaged supermarket for supplies.

Japan's Kyodo news agency said about 300,000 people were evacuated nationwide, many seeking refuge in shelters, wrapped in blankets, some clutching each other sobbing.

It said 5.5 million people were without power, while 3,400 buildings had either been destroyed or damaged. Four trains were unaccounted for after the tsunami.

In Tokyo, the usually bustling central districts were deserted on Saturday night, and the few in bars and restaurants were glued to television coverage of the disaster.

"Even in the bar we kept staring at the news," said Kasumi, a 26-year-old woman meeting a friend for a drink in the central district of Akasaka. "I looked at the tsunami swallowing houses and it seemed like a film."

NO REPEAT OF CHERNOBYL - EXPERTS

The blast at the nuclear plant raised fears of a meltdown at the power facility.

Experts had earlier said Japan should not expect a repeat of Chernobyl. They said pictures of mist above the plant suggested only small amounts of radiation had been expelled as part of measures to ensure its stability, far from the radioactive clouds Chernobyl spewed out 25 years ago.

Plant operator TEPCO has had a rocky past in an industry plagued by scandal. In 2002, the president of the country's largest power utility was forced to resign along with four other senior executives, taking responsibility for suspected falsification of nuclear plant safety records.

Many Japanese flooded social networking sites with worries about the plant.

"I can't trust TEPCO," said a person with the handlename Tanuki Atsushi on mixi, the Japanese social networking site.

The earthquake and tsunami, and now the radiation leak, present Japan's government with its biggest challenge in a generation.

The disaster struck as the world's third-largest economy had been showing signs of reviving from an economic contraction in the final quarter of last year. It raised the prospect of major disruptions for many key businesses and a massive repair bill running into tens of billions of dollars.

Foreign countries have started to send disaster relief teams to help Japan, with the United Nations sending a group to help coordinate work.

The earthquake was the fifth most powerful to hit the world in the past century. It surpassed the Great Kant quake of September 1, 1923, which had a magnitude of 7.9 and killed more than 140,000 people in the Tokyo area. (Reuters)

Big Bang machines sets power record


Big Bang machines sets power record – The world's largest atom smasher broke the record for proton acceleration Monday, sending beams of the particles at 1.18 trillion electron volts around the massive machine.

The Large Hadron Collider eclipsed the previous high of 0.98 1 TeV held by Fermilab, outside Chicago, since 2001, the European Organization for Nuclear Research, also known as CERN, said.

The latest success, which came early in the morning, is part of the preparation to reach even higher levels of energy for significant experiments next year on the make-up of matter and the universe.

It comes on top of a rapid series of operating advances for the $10 billion machine, which underwent extensive repairs and improvements after it collapsed during the opening phase last year.

CERN Director-General Rolf Heuer said early advances in the machine located in a 17-mile (27-kilometer) tunnel under the Swiss-French border have been "fantastic."

"However, we are continuing to take it step by step, and there is still a lot to do before we start physics in 2010," Heuer said in a statement. "I'm keeping my champagne on ice until then."

The organization hopes the next major step will be to collide the proton beams at about 1.2 TeV before Christmas for an initial look at the tiny particles and what forces might be created.

Ultimately, scientists want to create conditions like those 1 trillionth to 2 trillionths of a second after the Big Bang — which scientists think marked the creation of the universe billions of years ago.

Physicists also hope the collider will help them see and understand other suspected phenomena, such as dark matter, antimatter and supersymmetry.

The level reached Monday isn't significantly higher than what Fermilab has been doing, and real advances are not expected until the LHC raises each beam to 3.5 TeV during the first half of next year.

CERN said one of the two small beams of protons first broke the energy level Sunday evening when it was accelerated from the initial operating energy of 450 billion electron volts late Sunday evening.

"Three hours later both LHC beams were successfully accelerated to 1.18 TeV," shortly after midnight, the organization said.

Beams were colliding last week at low energy, to make sure the machine was working properly. But they have yet to be smashed together at higher intensity.

Steve Myers, CERN's research and technology director, said he had been at CERN when it switched on the last major particle accelerator, the Large Electron-Positron collider that operated from 1989-2000.

"I thought that was a great machine to operate, but this is something else," he said. "What took us days or weeks with LEP, we're doing in hours with the LHC. So far, it all augurs well for a great research program."

CERN said operators will continue preparing the 2,000 superconducting magnets and other parts so that the energy can be increased safely.

Attempts to make new discoveries at the LHC are scheduled for the first quarter of 2010, at a collision energy of 7 TeV (3.5 TeV per beam).

The electron volt is an extremely small measure used in particle physics. One TeV is about the energy of the motion of a flying mosquito, but it becomes signficant in the submicroscopic collisions of the collider.

The energy is concentrated in the hairline beams of particles that whiz around the accelerator at near the speed of light. Although apparently small to the outsider, CERN uses a great amount of electricity and powerful equipment to raise the energy of the beam.

The speed can increase only slightly when the accelerator steps up the power, but that raises the force with which the protons will collide, revealing more insight into what makes them up.

It may take several years before the LHC can make the discovery of the elusive Higgs boson, the particle or field that theoretically gives mass to other particles. That is widely expected to deserve the Nobel Prize for physics.

The LHC operates at nearly absolute zero temperature, colder than outer space, which allows the superconducting magnets to guide the protons most efficiently.

Physicists have used smaller, room-temperature colliders for decades to study the atom. They once thought protons and neutrons were the smallest components of the atom's nucleus, but the colliders showed that they are made of quarks and gluons and that there are other forces and particles.

More than 8,000 physicists from labs around the world also have work planned for the Large Hadron Collider. The organization is run by its 20 European member nations, with support from other countries, including observers from Japan, India, Russia and the United States, which have made big contributions.

Taiwan makes multi-tasking robot


Taiwan makes multi-tasking robot. Taiwan researchers have invented a robot that can act as a receptionist, tour guide, security guard and doctor's aide, the latest offering from an island seeking to make its name in the global robotics market.

The 60 kg interactive robot named Monica can film, then recognise people well enough to admit them into an office building or send an emergency text message to a human security guard, project leader Ren Luo said.

Sensory functions also allow it to interact remotely between doctors and patients, especially when a patient falls.

Tourists could also use the 100 cm tall robot to give them directions.

"Within the robot community, this is pretty impressive because it can replace so many human functions," said Luo, a professor at National Taiwan University.

Long a powerhouse for personal computers, Taiwan is eyeing a share of the $24 billion robotics market, taking on larger foreign rivals such as Japan as margins in the island's chip and PC industries come under pressure.

Taiwan aims to take a seven percent share of the global robotics market and exports worldwide, worth T$250 billion ($10.4 billion) by 2015, according to Taiwan's Precision Machinery Research & Development Center.

Four university instructors, funded by T$58 million ($2.43 million) from the Taiwan government, spent the past year building a pair of Monica robots, which powered up on Monday.

The researchers have already spoken with a manufacturer about mass producing Monica for consumers, Luo said. Current price tag is T$400,000 Taiwan dollars ($16,793), he said.

Developers globally are also working on robots for household assistance and dangerous tasks normally performed by humans, including bomb detection and disposal. ( tvnz.co.nz )
