Question - 453

Connect the three images from (the viewer's) left to right in that order.

Hints: Not many attempts. I guess the question doesn't give much to work with. The best hint I can give is that the last visual got an Ig Noble prize (unjustifiably in my opinion).

Answer: These are the three longest running scientific experiments in the world. They are in order the Oxford electric bell (which has been ringing continuously for 160 years now and works on electrostatic principles), the Beverley Clock (which has been ticking since 1864 and derives its energy from atmospheric pressure and temperature variations) and the pitch drop experiment (which was set up in 1927 and demonstrates that pitch while looking solid really is a high viscosity liquid). Since the pitch drop experiment has been running, 8 drops have fallen and it can be a very existential experience to watch the experiment live during work hours. I recommend it to all of you. Jaggi, Matti Tapaninen, Adi, Rahul Trivedi (who worries his own research is slated to join the list) and Nihar got it. Well done all.

Aside: I accidentally pressed the comment reject button and only a quick print screen saved the names of the people who had answered. Blogger has no way of undoing a reject apparently.
