I was in this lecture when he gave it. It was to around 150 or so inner city 14 yr old schoolkids and their teachers in London in '07. The filming doesn't show it but it was a tough crowd: he handled them exceptionally well. I spoke to him after the lecture and before taking my own students back on the bus to my school in East London: he seemed like a genuinely good guy. I could see he tried to pitch the delivery to suit and try to engage the actual audience in the lecture hall. He succeeded. It's a tricky balancing act, not knowing which students from any of the 8 schools that attended, had covered what material already. We've invited him to school to give six talks so far to different yeargroups since '07; to his credit he's always done this willingly and at no cost to us. His direct input has changed how some of my science staff do their own teaching and this in turn influences our students positively. I'd like to thank him here for all the great outreach work he's done for us over the years.
i just started at exeter and pete was giving away textbooks (i have his former copy of optical physics by lipson with his name inside it) i think he's stepped down or smth
Fair enough, I was wondering at the pitch he was taking, but if he's trying to make it more entertaining for teenagers then good on him. I thought initially he was talking to University students....
13:17 Pit viper, the camera is a thermo-electric IR camera (it exploits the Seebeck effect); my question is does the snake use thermoelectrics? The test would be to see if it can see pray in the dark through glass. Glass is thermolectric, air is not.
You got that right, with this presentation or called lecture. I learned something very interesting. With this cool topic, I know much stuff to learn about it. Thanks!
+Technology outdoors Each color has it's own frequency range. I've mapped out the matrix of time, sound, and light so that it proves that unless you use the objective color system for the notes, then people with chroesthesia are actually "crazy". How we perceive color may be subjective, but, each color is objectively placed within the RGB system. it's rooted in time (Hz). for example, Green is objectively in the center of the piano, just as Green is objectively in the center of the rainbow. This isn't pseudoscience, anymore. There are 12 hours on the clock, 12 notes in music, and 12 colors in art. All is connected on this vibrational level. This is the end of time as you know it. The end of something marks the beginning of something new. I've figured out the universe. I win. :)
Has anyone done calculations to produce a predictive model for the size of primer field bowls? It seams to me you could take measurements on some of the gas giants where you can calculate the total mass of the planets and measure the rings found at its poles that match the rings in primer field theory. I would think you could determine some sort of ratio and make a predictive model that scales to the molecular, planetary, solar and galaxy levels ….. magnetic bowl sizes that may predict the size of stars planets mater itself, etc. There are observable characteristics in nature around us.
Am I the only one who caught the mistake from 16:20 to 16:24? If you are in a dark room, your pupils will be dilated, not shrunk. The reason the doctor needs to put the chemical in the eye is to ensure it remains dilated as the doctor shines light into the eye to look at the retina. What an elementary mistake.
Isn't the color white rather than ultraviolet. The board on which he's pointing on is white, but without light it appears black. But is red no longer red when less light is pointed at it, or is red always red, regardless of how much light is projected onto it?
I do wish people would stop saying that the three types of cones are sensitive to the three primary colours of red, green and blue. The so-called red and green cones are actually sensitive to very similar range of colours, so much so that it would be more accurate to call them lime, green and blue cones.
I was studying the numeric value between colors, and, realized that whole system needs revision. However, I could only find information through Wikipedia on it. They seem to change often. My question is, how are the frequency of colors determined? How can one look at a specific saturation of color, such as 732,274,744,098,816 Hz, to determine exactly which adjective to call this range? I believe this color is indigo, but, I need proof. Who can show me what it looks like? How do we do this? If one could explain the problems science is having to make the precise determination, I can tell you exactly how to fix it.
Erm ....i'm afraid there's a slight over-generalization here. Red is red because either 1. it absorbs green (specifically the complementary green of red) 2. it absorbs all wavelenghts except red in fact, if an object absorbs green, it looks red even if it transmits several other wavelenghts like yellow and blue
If you ask a physicist what is his idea of yellow light, he will tell you that it is transversal electromagnetic waves of wavelength in the neighborhood of 590 millimicrons. If you ask him: But where does yellow come in? he will say: _In my picture not at all,_ but these kinds of vibrations, when they hit the retina of a healthy eye, give the person whose eye it is the sensation of yellow. (Emphasis added.) ~Schrödinger, _What Is Life?_
There are no colours, only what evolutionary biology has potentially randomly settled on allowing selection of things in the environment. It's why dogs see differently etc. Schodinger should concentrate on keeping his cat alive.
Good lecture. I'd be cool if he explained why mandrills have Structural Coloration in their buttocks as an extra example not associated with micro structures like butterflies do.
White light is not made up of the 6 or 7 spectral color emissions that we see when white light is diffracted or split by a prism. It is the atomic nature or arrangement of our gaseous atmosphere which is more responsible for the splitting up of white light into its spectral arrangement. The mostly carbon dioxide atmosphere of the planet Mars would show an entirely different arrangement of spectral emission than what we observe within Earth's atmosphere. But, I am sure that you already know this. A gas spectrometer gives rise to this understanding.
I think paying 4 light is so wrong when we could all use one big light and fiberoptics through magnifacation its been possible and im crying foul get on i people think about it
The scientific worldview is only concerned with mechanisms in 'parts to whole' relationships; explaining arbitrarily the inquiry: "How is it...?" If that is good enough for you then 'that's great'... but it's certainly not philosophy.
"Colour alternative vision", "colour standard vision", "my eyes aren't perfect, don't get me wrong"... isn't it too much PC and kowtow? It's defective cone cells, not "alternative" cone cells. Jeez...
You are just extrapolating everything for the sake of evolution propaganda..examples that you used have nothing to do with evolution they can perfectly be explained in a more intelligent way. Intelligent design. Poor students! you've just gotten a very tendentious teacher.
Yes, evolution is a dead dog as modern biology reveals - Darwin was wrong! Shame scientists like this guy have to reiterate the propaganda to developing minds in order to beguile them into the religion of atheism when so many cutting edge scientists in multiple fields from physics, biology, palaeontology to cosmology and chemistry have made it clear - there is zero evidence for macroevolution in any of the fields.
yes, i cant watch it. he's acting like a busker for my attention.... I'm watching the video . . , I'd love to follow the lecture, stop talking to me like I'm an 8 year old . . . even 10 seconds is too long .

If this guy was my physics teacher growing up, maybe I wouldn't have hated physics so much. Great lecture!
This guy really knows how to teach and get your attention. Thanks for sharing this :)
Diogo, its passion to the subjet matter.
Very good lecture professor. I could not stop the video in the middle. I listen the 65 minutes with full of joy. Thank you professor..
Well done, absolutely great passionate lecture, with crystal clear explanation.
I'd love to be as engaging as he is. What an excellent lecture!!

this guy is my university lecturer, he's so fucking good
This guy is such a legend
Excellent lecture. Inspirational and Informative :)
I would've missed this if I didn't know English. Coming from a non English speaking country. Thank you professor and the internet 🙏
Thank you very much, great conference and very entertaining
You got that right, with this presentation or called lecture. I learned something very interesting. With this cool topic, I know much stuff to learn about it. Thanks!
Is there a program or website where you can type in a specific THz frequency and see the exact wavelength of such specific frequencies?

Very engaging presenter. There is some pretty amazing science out there.....
You see iridescence every time you look at the back of a CD. The pits are small enough to cause the diffraction of light
I do wish people would stop saying that the three types of cones are sensitive to the three primary colours of red, green and blue. The so-called red and green cones are actually sensitive to very similar range of colours, so much so that it would be more accurate to call them lime, green and blue cones.
excellent explanation in practical way...........
really he give deep insight to see a object
thanks
Now this is some great talk !

Please keep up the good work 👏 👏 👏
There are 3 shapes: a yellow square, a brown circle, and the green rectangle encasing both.
If you ask a physicist what is his idea of yellow light, he will tell you that it is transversal electromagnetic waves of wavelength in the neighborhood of 590 millimicrons. If you ask him: But where does yellow come in? he will say: _In my picture not at all,_ but these kinds of vibrations, when they hit the retina of a healthy eye, give the person whose eye it is the sensation of yellow.

I wish I had a teacher/lecturer like him. Most of the teachers in my school are sleeping.
Beautiful lecture,♥️
This answers a lot of things , thank you :)

one word. perfect
Excelente video
Long time ago but I was impressed
1:01:50 "look, a butterfly"
that is a sunset moth come on
otherwise an excellent lecture
the lecture is full of mistakes actually...
thanks
Real science 👍👍👍
The frustrating thing here is that Anaconda's vid of Nicky Whatever has more views than this
That's fucking awesome.
I couldn't stop thinking of Doctor who, while he was explaining all of this...
very interesting
1 hour video?
Ain't NOBODY got time for dat!
my fav is @8:00
1:00:59
Feminism is gushing out of him!
Way to go to equality.
👍

29:20 woooo
Magenta? Cyan?
Vukusic ... A Chetnik?
I enjoyed 5th grade the first time.... what a fucking hustle. Hey guess what 1 plus 1 is two...wow

21:30 I thought I was actually color blind for a second hahahaha
Clark Margaret Martin Kenneth Gonzalez William
ok but why would he hOLD THAT SNAKE NO
A beet color is darker.
poor Ben got the hard job
No those are printed colours.
AM PROUD BEING BLACK COZ AM A MIXTURE OF ALL INGREDIENTS
2:21 low key britney spears diss..
How dare you sir!!
8:33 "that clearly is violet"
haha wtf this color is SO NOT violet haha...
Lol. It's a lecture about colour, and he shows an image in black and white and asks what is wrong with it.
"Colour alternative vision", "colour standard vision", "my eyes aren't perfect, don't get me wrong"... isn't it too much PC and kowtow? It's defective cone cells, not "alternative" cone cells. Jeez...
Color is not light.
!!!!!!!!!!!!!!!!!
the girl in the front row is really hot!
double negative !

This guy speaks like tabloid papers write.
yes, i cant watch it.
