- The Institute of Physics Schools and Colleges Lecture 2008. Delivered by science presenter and rock guitarist Dr Mark Lewney.
Rock guitars, superstrings, 11 dimensions and the world's largest and highest energy accelerator are the prime ingredients for the loudest lecture to date. This lecture reveals how:
Rock guitars make their distinctive sounds;
String vibrations might answer questions about the Big Bang;
The LHC - the biggest experiment every built 0 may let us peek into extra dimensions

Saw the Doctor himself today at a lecture in Warwick. Talked about how we're all made of maths, then turned Bohemian Rhapsody into a song about how Brian Cox can't explain matter to him, and how he's banned from the RSPCA for attempting schrodinger's cat in real life. It was glorious.

@@calebjones-mt1qq Nice! Lucky to have a dad like that.
Wow! Great lecture. I really wish that I had someone to teach physics to me like that during my school days, rather than me spending a good part of my undergrad in figuring out the connections of physics with the universe on my own. Truly loved Dr. Lewney's utter madness and simplistic way of viewing physics.
Awesome! I am taking a calculus-based physics in college and this explains much of what I did not learn in high school, which was over 30 years ago.
I saw dr mark lewney at the Big Bang fair he was amazing
was it called tv and space? something like that and was it in the royal society.
you can lay the guitar flat, sprinkle some fine sawdust on the board and excite the strings. the dust will settle where the board vibrates the least
36:00
"There's no such thing as 'before time.' There's no such thing as 'next to space,' because that would be space as well. There's no such thing as 'outside space-time.'"
Brilliant!
wow ! great lesson Mark.. string theory !!!! i'm a musician and you opened me a new world..or better..new worlds. did you write a book? i have to know more..more ..more !! :)
Nice thing Dr Mark Lewney did Phd on ..Very nice and non boring lecture unlike my lecturers and professors :P
Correction just realized I miss a while interval
Root = 1
Minor second is 2
Major second is 3
minor third is 4
Major third is 5
Forth is 6
Tritone is 7
Fifth is 8
Minor 6th is 9
Maj 6th is 10
Min 7 is eleven
Maj 7 is twelve
And then active is technically 13 also a harmonic of the root so technically 13 degrees from your root tour are at the original note bit another pitch
Also 12 musical notes possible
A-A#-B-C-C#-D-D#-E-F-F#-G-G#
now something interesting if you look directly at music an physics maybe nothing other then just coincidence bit between every music note there is a sharp # (or flat)
Now notice B-C and E-F the only 2 notes that have no intervals between them. It's not possible to create a C# or a E# "wave" b and c are so closely related they can't be separated (place a tone/wave between them) kinda like how space and time are so closely related ;)
OK speaking as a music student not as a physics student (although interested in sciences and physics) I am a bit perplexed in the connection of music with some of this. for example stating 11 dimensions when in fact there are 12 degrees of notes from one not to its office/harmonic .
root/tonic = 1
minor 2nd = 2
major 2nd = 3
minor 3rd =4
major 3rd = 5
4th = 6
fifth = 7
minor 6th = 8
major 6th = 9
minor 7th = 10
major 7th = 11
octive (referred to harmonic depending) = 12
so where do we come up
look up roger penrose aeons, a quite tidy theory of the big bang.
Insightful and very interesting. Yes. One day we might even find definitive proof to these theories, even. Time will tell. But, we shouldn't dismiss it as just conjecture. Just because it is a theory doesn't mean it isn't true, or so the converse.
Dr. Lewney...the Hanibal Lecter of the Guitar World. LOL
Good video Doc! Carry on mate!
Very cool! 👍
In real life, 48:17 scared the cap out of me!:D
If string theory is so closely related to music because of waves is there another 2 dimensions/degrees/anything like space time that is so close to another other can't be separated? Maybe resulting is 12 full degrees or dimensions like an active of a vibrating sting and not 11 ?
awesome
Cannot imagine better person to confirm or bust the myth of tonewood in electric guitars !?
He neglects to point out that the subharmonics are noncommutative phase with the overtone harmonics.
Please be my physics teacher!
Very nice thank you :)
30:00 I was arguing this with my science teacher back in 2002 or 2003 as a representation of a reversal of cause and casuality and how the entire universe could be created from potential... or more exactly the potential of time travel to the point of just before the big bang (a 3 dimensional particle inserted into a 0 dimension universe) since the energy created by this acceleration from 0-1 in 0.0*10^(infinity) seconds...
even though he couldn't argue against it he was ready to let me fail physics since I couldn't persuade him...

I feel like Capaldi's Doctor could have been inspired in part by this guy.
hmmm. i discovered recently, or rather, had my suspicions confirmed that the universe is grey, colour is ENTIRELY invented in the brain and to "illustrate" this i've used sound as an example, sound obviously has no colour, but apparently there is a species of bat that can convert sound into 3D images, lower res than humans, but similar to what we would see with night vision goggles, and this implies that they could possibly colour those images depending on wavelengths and frequencies, again night vision goggles colour they world green, but this is done by the equipement, low light is in fact on a grey scale (or black scale more accurately) and the tech does the colouring, as does our brain, likewise infra red, the temperature has no intinsic colour, the camera interprets the temperature and colours hotspots red/yellow and cool spots blue, but heat itself is just wavelengths of light - greys. so, now i'm thinking there is no sound in the universe either, sound waves are typically air compressing and expanding at frequencies that vibrate our ears, it's in the brain that these frequencies and wavelengths get converted into sound.
i started thinking about this after seeing electron microscope pictures, what colour is the world really? followed by wondering if the red i see is the same "colour" as what YOU call red - there is no way to know because there is no window into the brain to see. i wonder if i am right about sound though, is sound an invention of the brain?
Mistake there. The strings can't be at the same tension because they don't have the same mass.
einarabelc5 no he is correct, the strings are at the same tension. An easy way to tell this is that it takes a similar amount of force to depress each string. mass and tension are independent
the strings are at appx the same tension, about 25 lbs. each. The masses are different because the pitches are different. you have 3 factors... length, mass, and tension. change any one and pitch changes. with guitars, the length is set ( not so on pianos _) the tension must be close or the structure is compromised, mass is all that there is to juggle pitch with
i know what you mean xD dudes a maniac in a good way
@ the metalheads in the crowd
Very disappointing that he uses the terms 'sound' and 'vibration' interchangeably.
What kind of ibanez is that?
pretty sure that's actually a richenbacker
It's definitely an Ibanez ;-)
Mass on a spring = )
I'm sure they aren't so bad! :)
office = octiv
The key word there is THEORY.
Is he teaching physics to middle school girls?
A hundred hats... hahaha.
Us freedom loving Americans would throw him in jail.
@Kampion if you think that it is a waste of time, don't watch it. Continue on with the closed and ignorant mind of yours.
