👨‍🏫A lecture about an 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. In fact, it holds the Guinness World Record for being the longest-running experiment. This experiment began in 1927 and has been going ever since.
It's called the 'pitch drop' experiment and it was created by Professor Thomas Parnell at the University of Queensland, Australia. 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.
You see, when pitch is at room temperature, it feels solid. You can easily break it with a hammer. However, it isn't in fact solid. At room temperature, pitch is many billions of times more viscous than water, but it's actually fluid.
In 1927, Professor Parnell took a sample of pitch. He heated it and poured it into a glass funnel. He allowed the pitch to cool and settle – for three years. He then turned the funnel upside down and cut the top off it.
Since then, the pitch has slowly dropped out of the funnel. How slowly? Well, the first drop took eight years to fall. It took another forty years for another five drops to fall. Today it's been almost 90 years since the experiment started. Only nine drops have fallen from the funnel. The last drop fell in April 2014 and the next one is expected to fall in the 2020s.
The experiment has a tragic story associated with it. Professor Parnell died without seeing a pitch drop. His replacement, Professor John Mainstone, became responsible for the pitch drop experiment from 1961. 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.
The pitch drop experiment is something we can all participate in now. There's a live web stream that allows anyone to watch the glass funnel and wait for the fateful moment. 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. It's interesting to see how a very slow event can spread news so quickly.

A talk about motivation

🗣So, we think we know how to motivate people, right? Offer them a reward. Do this and you'll get this. Do this faster, earn more money. Do this better than everyone else, here's a promotion. We offer incentives when we want people to do things. We do it at work, at school, even at home with our kids. Tidy your room and you can watch TV.
But when social psychologists test whether incentives work, they get surprising results. Sam Glucksberg, from Princeton University, America, set people a problem to solve and told them he was going to time them to see how long they took. Then he put them in two groups. He offered one group a reward for finishing fast. Five dollars for anyone finishing in the top 25 per cent and 20 dollars for the person who finished the fastest of all. To the other group he offered no incentive, but he told them he was going to use their times to calculate an average time.
The first group, the ones with the reward, solved the problem faster, you'd think, right? Well, no, they actually took three and a half minutes longer than the group who just thought they were being timed. Incentive didn't work. In fact, it made them slower. This experiment has been repeated, with the same results, many times. But in business we still offer bonuses, promotions and rewards to staff.
That's fine if we want them to do something simple, like chop wood. We'll pay you more if you chop the wood faster. An incentive works then. But if we want someone to do something complex, something creative, something where they have to think, rewards don't work. They might even have the opposite result, and make people perform worse. Another study, by Dan Ariely, showed that the bigger the reward, the worse the subjects performed on a complex task. The reward made them focus so hard on the result that they couldn't think creatively any more.
And this all matters because more and more simple jobs will become automated. We'll be left with creative, problem-solving jobs that computers will never do. And we need to find a way to motivate people to do those jobs when we've proved the traditional incentives don't work.
So what does work? Giving your workers freedom; freedom to work on the things they want to work on, freedom to choose when, where and how they work. Want to work from home three days a week, get up late and work into the night instead? Fine. Just do the job well. And evidence shows people who choose the way they work get results. Companies that give employees time during the week to work on things that interest them and are not part of their regular job achieve amazing things. Some of the big tech companies are good examples of this, with ping-pong tables and areas to relax in …

💫🌏☄️ Asteroid

A
In 2010, the planetary defence team at NASA had identified and logged 90 percent of the asteroids near Earth measuring 1km wide. These 'near-Earth objects', or NEOs, are the size of mountains and include anything within 50 million kilometres of Earth's orbit. With an estimated 50 left to log, NASA says none of the 887 it knows about are a significant danger to the planet.
B
Now NASA is working towards logging some of the smaller asteroids, those measuring 140 metres wide or more. Of the 25,000 estimated asteroids of this size, so far about 8,000 have been logged, leaving 17,000 unaccounted for. Considering that a 19-metre asteroid that exploded above the city of Chelyabinsk in Russia in 2013 injured 1,200 people, these middle-sized asteroids would be a serious danger if they enter Earth's orbit.
C
Whether NASA can find the remaining middle-sized NEOs depends on getting the money to build NEOCam, a 0.5-metre space telescope which would use infrared light to locate asteroids. If it did get the money, it could probably achieve its goal in ten years. Once logged, the planetary defence team would still need to work out how to defend the planet against being hit by the truly worrying asteroids – the PHAs.
D
'Potentially Hazardous Asteroids' are rocks close enough to pass within 7.5 million kilometres of Earth's orbit. NASA has created a map of 1,400 PHAs, none of which are expected to be a threat in the next one hundred years. With technology already available, NASA can track these objects and make predictions about possible impact, at which point two defence solutions could be launched.
E
The first is DART – the Double Asteroid Redirection Test. Plans are scheduled to test DART on the moon of an asteroid called Didymos. 'Didymoon' is 150 metres wide, orbiting its 800-metre mother, and hopefully the impact of DART will knock it out of its orbit enough for Earth-based telescopes to pick up.
F
Another suggested defence against a PHA on course to hit Earth is to blow it up using a nuclear weapon. It may sound like a plot from a film, and it was the subject of the 1998 film Armageddon, but the Hypervelocity Asteroid Mitigation Mission for Emergency Response (HAMMER) is a genuine NASA proposal. The eight-ton rockets would be fired at an approaching asteroid with the hope of bumping it off course. If the asteroid was too close to Earth for this plan to work, the rockets would carry nuclear bombs to blow it up instead.
