Magnetic Matterials

There are different classes of magnetic matterials. Invest a little bit of time to understand dia, para, ferro, anti ferro, and ferri magnetism. I will publish a supporting APP with this:

This is a cutting from the APP, it uses new maths , you can expand any question for details.

• 1^st Response "You can find out about the history"
• 1^st Question "What are the key Eras of development?"
• 4^th Response "The quantum Era"
• ---------

I will do a podcast soon explaining the new maths behind the generation of these APPs.  Any questions post a comment.

Newton's Third law (conservation of momentum)

Well this applies to a system of bodies, so the earlier work of talking about what a body is and impulse leads to this momentum law. I have real problems with just getting students to rote learn this.

What can I do with Newton One and Two

Newtons' first law leads to inertial frames. Actually listening to student's questions, requires honest answers here. I put forward limited and pseudo inertia frame. The Newton two is given a "d and t" and we declare work, kinetic energy, impulse and momentum

What is next after Quantum Mechanics.

This New Scientist article was a bit hard for me to read.  Mostly there is a well known distinction between causality (one thing effecting the next) and simultaneity. so where do you go from here with this article? Also entanglement does not violate causality... but you have to really go into it.  Worth listening to but you would not want to learn you physics from this article. Podcast

Review of Rutherford

Also in the podcast I doubted my recall that Rutherford was a Kiwi, but that is all true. Podcast

From the syllabus:

Structure of the Atom

Inquiry question: How is it known that atoms are made up of protons, neutrons and electrons?

Students:
● investigate, assess and model the experimental evidence supporting the existence and properties of the electron, including:
 – early experiments examining the nature of cathode rays
– Thomson’s charge-to-mass experiment
 – Millikan's oil drop experiment (ACSPH026)

 ● investigate, assess and model the experimental evidence supporting the nuclear model of the atom, including:
 – the Geiger-Marsden experiment
 – Rutherford’s atomic model
– Chadwick’s discovery of the neutron (ACSPH026)

Great fun Podcast

NSW Physics Syllabus pages 32 - 39 Year 11 content

Finally this is the content taught on the year before the final year "Year 11".  I just think suvat is not the best as it misses the opportunity to teach subscripts and subsubscripts and more, and also uses up cognitive load in rote learning rather than functional recall. The use of a vector equation for friction is a problem but many sources on the internet muck up this fundamental thing.

This is acceptable as the symbols are placed as vector labels, N is a reserved symbol for normal force.  Some problems here though, with the scale and positioning of the vectors. Obviously mg sin(theta) should be smaller than mg, but also the negative value is problematic when combined with the sense of the vector. In a body diagram all vectors act from the COM which is the centre of rotation. You are allowed to translate the vectors for clarity of the diagram but you should use a dashed extension line through the COM. As drawn this shows a anticlockwise torque. Also strictly speaking you should not use redundant or non real forces on the body diagram. Using Australian convention only there should be a <==== double resultant vector where the mgsin(theta) on is drawn labeled  mg sin (theta) - mu N. All seems small change really, but... it is the clarity necessary for learning. Podcast

Cosmos Magazine Reading with Commentary - The wave particle theory

From my background I am always going to have difficulties with the Copenhagen "Wave-Particle Duality" and classical electrons etc.

I try to explain Entanglement from stuff I did in the lab.

About 10 years ago I just absent mindedly churned out 1000 or so "artworks" in a few months. Kids absolutely loved them, but art experts said they were rubbish.  I just used  a colour pallet from lasers and arranged things to map mathematical functions. This one just says that entanglement doesn't violate causality. Although I have remembered the key ideas, after the ops it is still foggy.

Cosmos Magazine Reading with Commentary - How big is the Universe?

I read this really well written article by Cathal O'Connell. The general idea is brain rest after a period of sickness. I struggled with 400,000 year age where I remembered 380,000 from:

" When it originated some 380,000 years after the Big Bang—this time is generally known as the "time of last scattering" or the period of recombination or decoupling—the temperature of the universe was about 3000 K."

found in Wikipedia but I remember other sources. To be fair it probably took some time.

Of interest to me the image processing to take out the doppler shift from the CMB and the analysis of the bumps in the power spectrum Fourier frequency analysis of the CMB to support the inflation model.

The Planck data is so good it brings a tear to the eye.....

This all came out while I was sick, so I haven't yet read articles explaining what it means for inflation, cosmic strings and measures of dark matter/energy. We live in truly wondrous times.
