Have you ever had a leaking faucet? If yes, you may have been annoyed by the sound that it made. Just like the rest of us, University of Cambridge engineer Anurag Agarwal has had enough of the “plink” sound, so he decided to learn what creates the distinctive sound.

As it turns out, the sound is not made by the dropley but by a tiny pocket of air. Seems weird we are only learning this now, but it’s a mystery that scientists debated for over a hundred years.

Anurag Agarwal revealed that he started to take an interest in learning about the annoying sound that a dripping faucet made when he visited a friend in Brazil in 2016. He shared that his trip landed on a rainy period and he couldn’t ignore the water that steadily dripped through the leaky roof and fell into a bucket below.

Until recently, no one understood how dripping water makes that infuriating “plink.”

Anurag Agarwal said in a statement:

“A lot of work has been done on the physical mechanics of a dripping tap, but not very much has been done on the sound. But thanks to modern video and audio technology, we can finally find out exactly where the sound is coming from, which may help us to stop it.”

Agarwal and his research team published their findings in the journal Scientific Reports.

Instead of just ignoring the sound as most people do, Agarwal was annoyed yet intrigued at the same time.

“While I was being kept awake by the sound of water falling into a bucket placed underneath the leak, I started thinking about this problem. The next day I discussed it with my friend and another visiting academic, and we were all surprised that no one had actually answered the question of what causes the sound.”

To solve this mystery, Agarwal took his curiosity to an undergraduate lab at Cambridge.

He and his colleagues then set up an experiment to record droplets falling into a tank of water using high-speed cameras, an underwater microphone, and a microphone on dry land to capture when and how a falling droplet of water makes the sound.

Agarwal then discovered that soapy water prevents the “plink” sound. So who needs an expensive plumber when you can add dish soap to whatever container is catching the water drips?

Would you travel on a windowless plane? Emirates has been experimenting with new technology and you could find yourself booking a flight with a virtual window seat in the future.

It might sound like a nightmare for those who have claustrophobia, but a new design from the airline plans to remove windows from aircraft. This idea was already tested in Emirates’ Boeing 777 last year with its first class cabin, where it has virtual windows in the middle suites.

The "windows" use real-time fiber-optic camera technology to provide virtual views of the outside world.

First, there are the keypads, then the touchscreen, and now all you need are your eyes to control your smartphone. Now, it seems that you don't even need your fingers while using your phone anymore, as a scholarship student Matt Moss discovered a brand new possibility when he attended this year’s edition of Apple’s Worldwide Developers Conference.

Matt was able to test out Apple’s iOS 12 developer beta and started to play around with it. While doing so, the student found out that the ARKit 2.0, which is a augmented reality platform, offered up an exciting technology.

Controlling your phone with your thumbs could soon become a thing of the past.

China dethroned the United States for eight years for having the fastest supercomputer, but the latter has now reclaimed bragging rights. China’s Tianhe-1A took the top spot in 2010, and introduced the Sunway TaihuLight five years ago, which is a better verson of the one that they already launched before. Now, the US is home to the new supercomputer, dubbed as the Summit, that's more than twice as powerful as China's fastest.

US scientists have unveiled the world's most powerful and smartest scientific supercomputer that can complete over 200,000 trillion calculations per second - providing unprecedented computing power for research in energy, advanced materials, and artificial intelligence.

Summit will be eight times more powerful than its previous top-ranked system, Titan.
