Good recording quality: While audio doesn’t need to be podcast quality, recordings should be intelligible and free from hiss, rumbles, echoes, or the excessive background noise that plagues poorer-quality recordings.The UX560 is also the slimmest recorder we tested-at 0.43 inch thick it can easily fit in a shirt or pants pocket. Like many of the other recorders we looked at, it comes with an adequate amount of onboard storage (4 GB) but accepts microSD cards, so you can record and store hundreds of hours of recorded audio should you need it. It also offers a better collection of features than the other models we tested, with an easy-to-navigate menu system, a bright backlit screen, 39 hours of recording time (in MP3 format), 27-hour battery life, voice-activated recording to pause and restart after silences, and a pop-out USB 3.0 connector that lets you recharge the recorder and transfer files to a computer easily. It produces clear, understandable audio in classroom, quiet office, and noisy coffee shop settings. In a new round of testing in mid-2017, the UX560 received the highest overall ratings from our panel of test listeners. It's interesting to see how a very slow event can spread news so quickly.The UX560 is similar to our previous, now-discontinued pick, also from Sony. A similar experiment to the Queensland pitch drop was set up in Dublin, and the video of the moment the pitch actually dropped went viral on the internet. There's a live web stream that allows anyone to watch the glass funnel and wait for the fateful moment. The pitch drop experiment is something we can all participate in now. He held the job for 52 years, and missed seeing the drop fall three times – by a day in 1977, by just five minutes in 1988 and finally in 2000, when the webcam that was recording the experiment suffered a power outage for 20 minutes, during which time the pitch dropped. His replacement, Professor John Mainstone, became responsible for the pitch drop experiment from 1961. Professor Parnell died without seeing a pitch drop.

The experiment has a tragic story associated with it. The last drop fell in April 2014 and the next one is expected to fall in the 2020s. Only nine drops have fallen from the funnel. Today it's been almost 90 years since the experiment started. It took another forty years for another five drops to fall. How slowly? Well, the first drop took eight years to fall. Since then, the pitch has slowly dropped out of the funnel. He then turned the funnel upside down and cut the top off it.

He allowed the pitch to cool and settle – for three years. He heated it and poured it into a glass funnel. In 1927, Professor Parnell took a sample of pitch. At room temperature, pitch is many billions of times more viscous than water, but it's actually fluid. You see, when pitch is at room temperature, it feels solid. Parnell was the university's first physics professor, and he wanted to show in this experiment that everyday materials, such as pitch, can have quite surprising properties. It's called the 'pitch drop' experiment and it was created by Professor Thomas Parnell at the University of Queensland, Australia. This experiment began in 1927 and has been going ever since. In fact, it holds the Guinness World Record for being the longest-running experiment. In today's lecture we're going to be talking about experiments, and I thought it might be interesting for you all to learn about the world's oldest continuously running laboratory experiment that is still going today.
