  • So I recently spoke to Henry from the YouTube channel minute physics, and he was telling me about some of the concerns he has with the way physics is taught in high schools, particularly the United States.

  • He's actually now created a video letter to the newly re elected president, and you can see that on his channel.

  • I'll be mentioning again later.

  • But what I've done here at 60 symbols, I've spoken to some of our professors.

  • Now, as you know, these people teach at the University of Nottingham.

  • So they have a lot of experience with physics students who've just come out of high school.

  • And I asked them what they thought about the way physics is being taught in UK schools, even for those people who don't go on to physics in university.

  • Don't go on to engineering a maths or chemistry.

  • Wherever in university, we have to teach the sciences.

  • I mean, I actually I actually went back and had a look at my These are my A level on notes.

  • Most of what is here is old stuff, all stuff that we've known for donkey's years.

  • Okay, so this are what's called the S on the year to effective the air level examinations.

  • And this is the curriculum.

  • The guts of pretty exciting physics.

  • Quantum physics.

  • They got special relativity for May That looks like a reasonably good balance.

  • I'm very impressed with the breath of physics that they're doing all this old, old, old stuff being around for hundreds of years rubbish old, old, old and then right at the end.

  • You do some quantum theory, a tiny little bit of quantum theory.

  • But the downside could be that because they tried to cover such a breath of areas now they still only got two years in which to do it for their A levels.

  • Then they're struggling to cover things in the kind to the kind of depth that we're expecting them to be covered.

  • One thing that might be difficult to see coming across from that on the screen is just how much the mathematical level has dropped over there over the last few years.

  • A little bit of the photoelectric effect.

  • This is about it.

  • This is about all that we did.

  • The reason is really, really frustrating because this is now established off.

  • This is being around for 100 years on DDE.

  • What Really, it's reality as well.

  • This is I mean, quantum theory in particular, is one of the most well tested theories There is.

  • Also, I feel incredibly incredibly sorry for the students coming in who come from air level, come from high school with a completely different view of what physics actually is.

  • And then they come here and they get an awful lot of mathematics, anything.

  • Why I didn't sign up to do a mathematics degree, ascended to do a physics degree on.

  • We have to continually tell them that maths is the language of physics.

  • You can re popular books on physics and on cosmology in particular, which doesn't have much maths.

  • But if you then want to actually get into the heart of the subject, you really have to know the maths.

  • This is where I start getting annoyed with with celebrities and what not.

  • I was listening to Radio one, and the other day Nick Grim Shore.

  • He's a radio deejay in the morning is taking over Chris Miles, which you know I'm happy with because Christmas annoys me.

  • But it's a Nick Grimshaw over that it was going on about somebody said they did maths or something, and he's going all maths economics.

  • I don't understand any of that.

  • Oh, no, I don't understand at all.

  • It's really, really hard on.

  • This is common.

  • It's cool toe to be afraid of maths on.

  • You know, when people like on the radio going on about how cool is to be afraid of Matt, then clearly, this is going to seep through society on then.

  • Teachers fear putting maths into into their physics and syllabus is because you know they don't want to frighten off students.

  • For example, calculus has been ripped out off a level physics.

  • You know, the fundamental Pierce's off, You know so much of physics.

  • I mean, I love coming here and talking about physics with you.

  • But when I look at what's written on that board behind you, that scares the life out of May, and if I knew I was gonna have to talk about that, I probably wouldn't come here.

  • Oh, is there a danger that you're going to scare away potentially excellent physicists of tomorrow by telling them the heart too early?

  • But it isn't.

  • It's not so Yes, absolutely.

  • So if you just when said loud, Let's go prove Fermat's last theorem, you know, in the air level.

  • And let's introduce you to all this weird and wonderful maths that you need the absolutely.

  • But I'm not saying that what I'm saying, you just they just need to go into a bit more depth in what they're already doing.

  • You know, my brother was we were talking about Schrodinger's cat on that, and he either sort of dismissed it as my ridiculous theory on.

  • I think people sort of wish it had been my theory.

  • But, you know, I think people sort of just think of quantum theory of relativity as being something that you don't really.

  • This is for another world.

  • It's something that on which to too difficult for me.

  • But it's nice.

  • It's the way it is in nature.

  • Quantum theory is really relativity.

  • Israel on it is important for everybody's you know Davy lives.

  • You know, all the computers and mobile phones are relying on certain aspects of quantum theory.

  • You know, you drive a car, use a satnav, you're using relativity, and you might say, OK, well, I don't really care that much about that, but you didn't care about that when you're in a plane.

  • If it was really sort of put in, that's Ah, at this early stage, you know, people who did a love of physics knew much more about quantum theory of relativity.

  • Even the ones that don't go on study, physics, university, then society would have this Maur embedded in their psyche.

  • Of course, one of the problems is both quantum theory on dhe relativity.

  • They do rely on a lot of maths, and I think it's math, someone, anything else that people fear.

  • And that's why, certainly when we get students coming, Thio not again.

  • And the one thing that they tend to struggle with his math more than physics.

  • And I think perhaps, really, it's the mass a levels that have to improve dramatically.

  • I have this right.

  • I went to university in 1979.

  • I went down to London and I went to my first maths lesson on this funny letter.

  • I kept appearing and I thought it was the one I thought it just couldn't be just a funny writing on.

  • Then I saw this.

  • I squared and it was minus one.

  • Of course, it's the introduction to imaginary numbers and I've never come across.

  • And I had no idea on DFAT I felt like quitting.

  • I thought, like I this is lecture one what chances of I got.

  • But of course, you you go and get a textbook, you and you start reading it and you you go through it.

  • And that's part of university, that self education.

  • You've just got to go and do it, and if you're prepared to do it, you'll be fine.

  • This is in the dark by It's a block by somebody called Peter Cole's who used to work here in Nottingham.

  • One thing he did some time ago was to put up his old level paper from 1979 so you can see the effect of pressure in the piston stands.

  • Six offered six by 10 to the four possibles.

  • Use this in the data given in lines 10 and 11 blah blah, blah, blah, blah.

  • If we move down, you can see again numbers, little problems.

  • Set them.

  • I work out what's going on.

  • Let's compare to a G.

  • C s C paper again if I can find the right one.

  • This is now 2011 science.

  • A general certificate of second secondary education.

  • The diagrams show four types of power station.

  • Each power station uses a different energy source to produce electricity, solar cells, ocean, much energy sources, Air B, C and D.

  • Now this'll is the point.

  • This is the point where you don't have to have done this course that don't question, of course, before I get all daily mail about this and going a ranting and raving, it's important to note that this is the first question.

  • It's on the fine dish interior of this.

  • This it, but not substantially hard or nothing like we saw for the old level.

  • So you can see what you're doing is a lot of multiple choice.

  • A lot of you know, matched words A, B, C and D with the numbers 1 to 4 in the sentence.

  • And this is another problem because now students, this is that you know it's 15 60.

  • Students are learning that instead of writing things out, what they have to do is plug the words in the sense and that that again causes huge problems when they get to university.

  • As much as we want to know about Shakespeare and I, what do I know about sex is not a great deal, but I know big, okay, And I think people who read Shakespeare professionally into Shakespeare for whatever should know about quantum theory at the level I know about Shakespeare in things like that, I think I think this is a This is almost a fear on on.

  • Call this almost as well, and you're not cool.

  • If you start trying to understand that stuff, it's too weird.

  • It's too hard.

  • No, it's the way it is.

  • If you'd like to see more from Ed, Phil or Tony, I've put all the interview footage on my extras Channel Nottingham Science and there are links on the screen.

  • They talk about a lot of stuff not covered in this video, and it's well worth a look.

  • If you've got a bit of time on your hands and if you haven't got a lot of time on your hands, there's always time for a quick, pithy minute physics video.

  • Make sure you've checked out Henry's video.
