I had study about Newton's experiment. He saw a apple falling from a tree then he asked himself why is a apple falling from tree. He invented gravity law.

I know the experiments done by Marie Curie and I think are wonderful. She and her hasband did many developments about radiactivity and found out two elements and they helped to development of the medicine advance en the fields like cancer treatment and radiology.

I know one. Actually it is not as scientific as the pitch drop thing, but it has a deeper meaning to mass production and the quality of goods produced.

Have you heard of the light bulb invented by Thomas Edison? Yes, the forefather of all obsolete lightbulbs that only last 1000 hrs. There is a centennial light still burning at Livermore Fire Station No 6 in California. And it was lit in 1901. This bulb however is not quite exactly, what Edison came up with, but the manufacturing was patented by a French engineer.

Among the most famous scientific experiments I remember the one of Guglielmo Marconi. He wasn't a scientist with an academic curriculum vitae. but an inventor and an entrepreneur. Eighteen ninety-five Marconi fulfilled his famous experiment: the transmission of a signal at a distance via radio waves.

I know about an experiment testing the broken windows theory. The testing was running by Philippe Zimbardo in 1969. He parked a car with no license plates and the hood up in the Bronx New York (a worker class neighborhood) and another one in Palo Alto California (a high class place). The Bronx’s car was completely vandalized in 24 hours. At the same time, the Palo Alto’s vehicle remained untouched after a week until Zimbardo himself broke a window with a hammer. Afterwards, the car was vandalized too. The conclusion: social apathy leads to a decrease in the sense of mutual regard and obligations of civility.

When I was coursing Physics at the university, I knew about the Focault Experiment, I was very surprised by this impressive experiment, this helped to demonstrate the rotation of earth many years ago.

Yes I listened there was something like an psychological experiment called “Rhythm”. In summary, it was about a woman in a room who put different things on a table, from bread to a gun, then she invited some people to came in and closed the door. For many hours she just stand without make a noise and the more hours passed the more aggressive people became. Its a little creepy but its interesting.

It is a hard topic, if we had on the experiment, we couldn't image what happen. Fortunately, I had it when I was in elementary school. But I can't remember clearly because the school hadn't enough condition for us to practise full time. With a few hours were impressed my memories. Moreover, practise experiment are made everybody to understand long time and be aware of the theme.

My first experiment was the dissection of the frog. Catching a frog is a very difficult task somehow I managed to catch it. I took the frog in the laboratory, dissected from the middle. I observed that the internal organs and system of the frog is very similar to humans.

I never heard about that experiment when I was studing at different Uni in queensland state. On my opinion, first few years it looked like really intresting experiment but time goes by it is more be like a guinness world record than scientific experiment. Because Dr Parnell already got his result (pitch is liquid)and there is nothing to wait new result or changes anymore. Only interesting thing is it has going long time thats it.
