The World's Loudest Sound Caused Shock Waves 10,000 Times That of a Hydrogen Bomb:

‘On 27 August 1883, Earth made the loudest noise in recorded history. Emanating from the island of Krakatoa, which sits between the islands of Java and Sumatra in Indonesia, the sound could be heard clearly almost 5,000 kilometres (3,100 miles) away and by people across 50 different geological locations around the world.’

‘According to Aatish Bhatia at Nautilus, about 3,200 kilometres (1,988 miles) away from Krakatoa, residents of New Guinea and Western Australia reported hearing "a series of loud reports, resembling those of artillery in a north-westerly direction". And over 4,800 kilometres (2,983 miles) away on the island of Rodrigues in the Indian Ocean, locals reported hearing what sounded to them like the distant roar of heavy gun fire.’

‘The sound was caused by a record-breaking volcanic eruption that sent smoke up almost 80 kilometres (50 miles) into the air as ash fell into the ocean some 20 kilometres (12.4 miles) away. Burning hot debris was shot from the mouth of Krakatoa's volcano at speeds of up to 2,575 kilometres per hour (1,600 mph), which is more than double the speed of sound.’

‘The event has been called the greatest natural disaster of the 19th century, because with such an incredible release of pressure also came severe consequences for the surrounding area. Shock waves from the eruption travelled around the world several times, and created a tsunami over 45 metres tall (148 feet) and weighing 600 tonnes, which ended up hitting the shores of Java and Sumatra and absolutely decimating their coastal regions.’

‘Far away in South African waters, ships were being rocked by another set of tsunamis. And you wouldn't have wanted to be on the water less than 100 kilometres (62 miles) from Krakatoa at the time, as Bhatia explains at Nautilus:
The British ship Norham Castle was 40 miles [64 kilometres] from Krakatoa at the time of the explosion. The ship's captain wrote in his log, "So violent are the explosions that the ear-drums of over half my crew have been shattered. My last thoughts are with my dear wife. I am convinced that the Day of Judgement has come."’

‘According to The Independent; the force of the blast was 10,000 times that of a hydrogen bomb, and Bhatia reports that the sound was registered at around 172 decibels over 160 kilometres away (100 miles).’

‘That's bonkers, seeing as the human threshold for pain is 130 decibels, and the sound of a jet engine when you're standing right next to it is 150 decibels.’ J⭐️

Sundar Pichai Becomes The Highest Paid CEO In US, Gets Stocks Worth $199 Million In Google

Sundar Pichai was named the new CEO (Chief Executive Officer) of Google in August 2015 in a significant restructuring at the search giant HQ. According to a regulatory filing by Google parent company, Alphabet Inc., Pichai has received a grant for 273,328 Class C Google stock units, worth about $199 million, which is set to make him the highest paid CEO in the United States.

However, the 273,328 shares will vest in quarterly phases through 2019 if he remains on the job, which means that he won’t be able to cash these shares all in at once.

Google may see the award as fair value for the work Pichai has done for the company over the years, as he took charge of its Android, Chrome and search business arms over the years, bringing Google nothing but success. According to Credit Suisse, the new shares put the value of Pichai’s Alphabet holdings at approximately $650 million.

Bloomberg reports that according to its data, the award is the biggest ever given to a Google executive officer. It is also Pichai’s first award since he took over as CEO in August 2015. The financial publication also notes the Alphabet filing revealed the company awarded $42.8 million in restricted stock to Diane Greene, former CEO of VMware, who is in charge of cloud business since November.

Earlier this month, Alphabet became the most valuable firm in the United States surpassing Apple, with its latest reports showing that the company broke quarterly profit forecasts on Monday, hitting consolidated revenue of $21.33 billion (£15bn) for the financial quarter ending December 31, an 18 percent increase from the $18.10 billion (£12.5bn) reported a year earlier.

Alphabet’s CFO Ruth Porat was handed shares worth $38 million which is on top of the $30 million signing bonus she received when she was poached away from Morgan Stanley last year.

You can surf net at 1Gbps with Qualcomm’s new Snapdragon X16 modem but no service provider provides that kind of speed as of now

While 75 percent of the world is surfing the Internet at speeds of less then 5Mbps, Qualcomm’s new modem chip can offer download speeds of upto 1Gbps.

Most modern smartphones with top end chips offer maximum speeds of 300Mbps or 450Mbps. The new Snapdragon X16 modem offers what are known as Category 16 LTE download speeds which are up to 1Gbps. The new chip will also let you upload at speeds of up to 150Mbps. However, the sad part is that there are few service providers who can provide users with that speed.

The new X16 chip differs in working from its predecessors, instead of using extra chunks of spectrum to send data faster, X16 makes better use of what’s available to it. It does that by using some fancy signal processing to squeeze more streams of data into the same old 20 MHz slices of spectrum your current phone makes use of. You can read more about the details in Qualcomm’s release.

As said above, a very few LTE networks would provide anywhere near 1Gbps speeds just yet—so it’s an investment in the future, rather than the present.

Energy harvested from this walking shoes can be used to charge your smartphone

Our shoes may become our next energy source. Thanks to a new energy harvesting and storage technology developed by the mechanical engineers at the University of Wisconsin-Madison. This technique can reduce reliance on batteries in mobile devices and charge your smartphone as you walk.

Tom Krupenkin, professor of mechanical engineering, and senior scientist J Ashley Taylor described the innovative energy-harvesting technology that can capture the power of human motion to charge mobile electronic devices such as smartphones and laptops.

This could enable a footwear-embedded energy harvester that captures energy produced by humans during walking and stores it for later use.

Power-generating shoes could be especially useful for the military, as soldiers currently carry heavy batteries to power their radios, GPS units, and night-vision goggles in the field. The advance could also provide a source of power to people in remote areas and developing countries that lack adequate electrical power grids.

“Human walking carries a lot of energy. Theoretical estimates show that it can produce up to 10 watts per shoe and that energy is just wasted as heat. A total of 20 watts from walking is not a small thing, especially compared to the power requirements of the majority of modern mobile devices,” explained Krupenkin.

Krupenkin and his colleague J. Ashley Taylor believe that this technology could be a game-changer in the energy space that could power a wide range of devices from your phone to your tablet to just about anything that requires batteries for operation.

A typical smartphone requires less than two watts of energy.

“We have been developing new methods of directly converting mechanical motion into electrical energy that are appropriate for this type of application,” Krupenkin noted in a paper published in the journal Scientific Reports.

The team has been working to develop new method of converting mechanical energy into electrical energy that would work for generating power from a human walker. The process the team is working on now is known as reverse electrowetting. This technique uses a conductive liquid that works with a nanofilm-coated surface that is able to produce electricity.

Researchers developed a ‘bubbler’ method, which combines reverse electrowetting with bubble growth and collapse. A bubbler has no moving mechanical parts and uses a pair of flat plates with a conductive liquid between them. The tiny holes in the bottom plate allow pressurized gas to enter and form tiny bubbles. The bubbles grow until they are large enough to touch the top plate, which causes the bubble to collapse.

The speedy, repetitive growth and collapse of bubbles pushes the conductive fluid back and forth, generating electrical charge. This method produces around 10 watts per square meter of surface and in the space of a shoe; the team believes that making 10 KW of power might be possible.

The findings were published in the journal Scientific Reports.

The engineers are looking for industry to commercialise the technology through their startup company, InStep NanoPower.

Researchers Accomplish Fastest Ever Data Transmission At A Blazing Speed Of 1.125 Tb/s

1GB is a for rookies, as scientists break record of data transmission rate at whopping 1.125 Tb/s

How would you like to download a 2GB movie in under 1 second. No, this is not fiction. Scientists at the University College London (UCL) in the Optical Networks Group have set a new record for the fastest ever data transmission rate for digital information between a single transmitter and receiver, by sending data optically at a rate of 1.125 Tb/s (terabits per second).

Lead researcher, Dr Robert Maher, UCL Electronic & Electrical Engineering, said in a press release: “While current state-of-the-art commercial optical transmission systems are capable of receiving single channel data rates of up to 100 gigabits per second (Gb/s), we are working with sophisticated equipment in our lab to design the next generation core networking and communications systems that can handle data signals at rates in excess of 1 terabit per second (Tb/s).

“For comparison this is almost 50,000 times greater than the average speed of a UK broadband connection of 24 megabits per second (Mb/s), which is the current speed defining “superfast” broadband. To give an example, the data rate we have achieved would allow the entire HD Games of Thrones series to be downloaded within one second.”

The study used procedures from digital signal processing and information theory to custom build an optical communications system with multiple transmitting channels and a single receiver. The study will be published today in Scientific Reports.

The researchers built the new optical system using fifteen different channels to send the data, each of them carrying an optical signal of different wavelength. Each channel is separately modulated, and they are all combined, which is then sent to a single optical receiver for detection. The team created a ‘super-channel’ by grouping the channels together. At the other end, a receiver with incredibly high bandwidth makes sense of it all.

“Using high-bandwidth super-receivers enables us to receive an entire super-channel in one go. Super-channels are becoming increasingly important for core optical communications systems, which transfer bulk data flows between large cities, countries or even continents. However, using a single receiver varies the levels of performance of each optical sub-channel so we had to finely optimise both the modulation format and code rate for each optical channel individually to maximise the net information data rate. This ultimately resulted in us achieving the greatest information rate ever recorded using a single receiver,” said Dr Robert Maher.

In this study, the researchers directly connected the transmitter to the receiver to get the maximum data rate. For their next experiment, they will need to link the transmitted to the receiver using optical fibres, which will cause the optical signals to become distorted as they travel through thousands of kilometres.

Soon this technology will percolate down to commercial use and we may also be able to enjoy breakneck speeds while surfing Internet or playing online games.

This world’s smallest optical switch uses only a single atom.

Physicists develop the world’s smallest optical switch using a single atom

Researchers at ETH Zurich in Switzerland have developed the equivalent of a single-atom photonic transistor by fabricating the world’s first single-atom optical switch to meet the exponential growth of data and faster transmission.

The scientists have developed the world’s smallest optical switch using a single atom and a modulator that is significantly smaller than the wavelength of light used in the system. This device converts information originally available in electrical form into optical signals. They do this by turning a laser on and off at the frequency of an incoming signal, thereby “modulating” the light to create an optical replication of the input transmission.

Incorporated in data centers in the tens of thousands across the world, modulators are relatively large as far as electronic devices are concerned. Currently, around 3 cm wide, the disadvantage of being large is that they take up a great deal of space when used in large numbers. However, if they are to be useful in future photonics-based devices, their size needs to be significantly reduced.

Developed by Professor Jürg Leuthold and his colleagues at ETH Zurich, the optical modulator operates at the level of individual atoms. In fact, the modulator is significantly smaller than the wavelength of light used in the system.

In telecommunications, optical signals are transmitted using laser light with a wavelength of 1.55 micrometers. Normally, an optical device cannot be smaller than the wavelength it should process.

Here’s how it works: silver and platinum pads are placed on top of an optical waveguide made of silicon with just an atom’s gap between them. Once voltage is applied to the silver pad, a single atom is drawn towards its furthermost point, closing up the gap and creating a circuit between the two pads. This makes it a switch as it flips and the state changes from ‘on’ to ‘off’ or vice versa. As soon as the voltage falls below a certain threshold again, a silver atom moves back and the process is repeated a million times.

As the light is beamed across the waveguide, it gets converted into surface plasmon, made up of electrons that oscillate at the frequency of the laser light. These electrons can pass through the single atom gap before being reconverted on the other side. By reconfiguring the design of the modulator, the light is effectively squashed to squeeze through the gap.

“Until recently, even I thought it was impossible for us to undercut this limit,” said lead researcher, Jürg Leuthold.

Using a high-performance computer, the researchers simulated the system that further allowed them to confirm that the short circuit at the tip of the silver point is brought about by a single atom.

As the plasmon has no other option than to pass through the bottleneck either completely or not at all, this makes it a truly digital signal – a one or a zero. “This allows us to create a digital switch, as with a transistor. We have been looking for a solution like this for a long time,” summarizes Leuthold.

While the researchers admit that the device is not yet ready for series production, Leuthold says that he has full confidence that this device could be possible in a few years with the introduction of 10-nm lithography.

Even though it has the advantage of operating at room temperature, unlike other devices that work using quantum effects at this order of magnitude, it still remains very slow for a modulator: so far, it only works for switching frequencies in the megahertz range or below. The ETH researchers want to fine-tune it for frequencies in the gigahertz to terahertz range.

Now, the team wants to improve the modulator production process so it’s suitable for large-scale use and reliable in operation. At present, fabrication is only successful in one out of every six attempts.

In order to continue his research into the nanomodulator, Leuthold has strengthened his team.
