The Cavendish Experiment - Sixty Symbols
Loading...
Uploaded by sixtysymbols on Jul 6, 2011
Henry Cavendish was an unusual man but also one of the first great scientists. Many of his discoveries remained hidden in his notebooks, but his name is still attached to the the extraordinary Cavendish Experiment.

I love these videos!
-
@clayphish Do you also answer the room ?
-
Cavendish is one of my favorite sciences ever!
-
ahh, the original socially awkward penguin.
-
I love professor's belly 3:15
-
@teslafredde Okay that makes sence. What about nearby objects, lamps, tables etc. were these removed?
-
@mozad655 To minimize the gravitational pull from any mass outside the instrument we measured the angle by using a light directed towards a mirror on the torsion pendulum. by standing approximately 6 meters from the measuring device we could measure the reflected lightbeam and thereby measuring the time of oscillation to calculate the equilibrium point, where the force of gravity is equal to the force from the torsion pendulum. I have no idea where the university received the instrument
-
@teslafredde Can you explain how you managed to eliminate the disturbing factor of your own gravitational atracting of the balls? How did you physically measure the angle of twist, without "stepping into" the experiement yourself and thus acting as source of inaccurancy? Also where did you get the instrument if I may ask?
-
I actually did the Cavendish experiment today with exactly the same instrument at my university! I came to the conclution that the Big G is approximately 6.792e-11N(m/kg)^2(not to bad considering the cruel means of measuring by eye), this experiment was both very intresting and educative. Highly recomended!

one of my close friends has a condition like that

He sounds like he has Autism/Aspergers.

@kmica2008 best part of the video xD
-
@UKNMajor It was autism!

A mix of all of them :)

You're forgiven - I just wanted to stick the boot in as you guy trained us to be pedantic. Sorry!
I hope you keep involved with the videos in your retirement.
All those lectures begrudgingly attended on cold winter mornings when bed seemed the preferable option, or at the end of long Mondays when the brain felt sore, I graduate and find myself watching you all on sixtysymbols!

I would give myself a fail if I said that in an exam. It is difficult to be spontaneous and exact when talking to the camera---there is no time for the speaker to edit what he or she says, so all sorts of mistakes creep in. But reading a script is not allowed by Brady, and if it were, then the videos would not be so good. So Mea culpa, maxima culpa if you'll forgive the expression.

Professor Bowley,
"He invented Hydrogen" (2:12)
I certainly hope we wouldn't get away with that in an exam!
-
@MisterDogshit the context in which the term strange was used is to describes a person of abnormal behaviour, I hardly think the professor said it wanting to insult him, no need to be angry about something so meaningless after all anyone interesting is strange in their own way. what I want to know is whether the professor watches the BBC QI show and/or Top Gear lol.

Press 6 for ball
-
@DeepGrey1A Just sounds like Extreme Anxiety, and the only way he could get around it was to not do the things he knows triggered it.
-
i went to henry cavendish primary school in balham. i've always wanted to know more about henry cavendish, all i knew was that he measured the weight of the earth. thank you sixty symbols ! was extremely interesting (:
-
I don't really think there's anything wrong with calling him "strange"... if he was unusual but we don't know what disorder he suffered from, then it's hard to know what to say about him
-
@sixtysymbols what do the professors think of the big bang theory? I'd like to hear their opinions on the show hah

I thoroughly enjoy every single video that 'Sixty Symbols' or 'Nottingham Science' produce!!!
