If anybody says he can think about quantum physics without getting giddy, that only shows he has not understood the first thing about them.

It's spring which means the daffodils are out in our garden and it's time to do the IA again. I do the IA at the end of the first year because: students have time students are enthusiastic students haven't forgotten the skills they have learnt students haven't been influenced by IA's in other subjects I have time to give feedback Some might think its a bit...
I was new to teaching IB and moved to a brand new school with no other Physics teacher and no resources at all... With the huge help from the InThinking Physics site I was able to put in place a course with no problems at all. It has been like having...
This site is well organized and thorough. It gives great insight into the content and how connections can be made for students. I have been using it to help me prepare for the 2016 assessment, and have used resources for each content area and laboratories...
InThinking Physics is a valuable resource. If you are teaching IB Physics for the first time, then it is an absolute must-have. The materials provided are practical, easy to follow and full of interesting resources.

Vibrations and wavesHi Stephen. I don't think so. You should mention that there is polarisation on reflection but no calculation.

Vibrations and wavesChris, Is Brewsters angle still on the specification? It is in the 2014 Physics fr the IB diploma oxford revision guide but not in any other books that I can see. Thanks

Ring of chargeHi, thanks for sharing. for the 2-d problem, I tried this on Phet also, but I thought the reason why the field did not cancel was the imperfection of my circle, and also that the 'field arrows' do not show how weak it really is. Your positive...

Brownian motionThanks Ylva; You just made Herman's day. He was hoping for a comment :-)

Brownian motionVery nice analysis, though!

I submitNo need to upload the PSOW. Just keep it somewhere safe in case its ever needed.

I submitOne last question Chris, do I need to upload my PSOW with the sample? I have been seeing conflicting information on this.
I am with you, Chris. This is strange. Thank you for your time.

Engineering PhysicsThis looks strange Work done = 610 J and heat transferred out of the gas = 1300 J. This means that heat into gas = 1910 J so efficiency = 6/19. The answer scheme is taking 1300 J into the gas. Strange how the MS acknowledges this but doesn't...
Thank you so much.

Engineering PhysicsI'll have a look at it later today.
Dear Chris. I have a doubt in the past paper M15/4/PHYSI/HP2/ENG/TZ2/XX question 7 part 2. It is about the thermodynamic cycle. I don't understand the efficiency calculation in the mark scheme. Efficiency = work done/ Total thermal energy...
