A well planned site with lots of informations in Physics!

Vinita Sharat, The Shri Ram School, India

This is a great resource for IB Physics teachers. I have been using it and will continue using the same in future. The resources of IA are great. I can strongly recommend to any Physics teacher of the world for this site. Thank you for maintaining the...

Arun Mukherjee, International School Of Penang (Uplands), Malaysia

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...

Don't look at the laser

16 September 2017

Have you ever wondered what it would be like to look at a laser? Shah wondered too but he's probably damaged his eyes enough looking at sunspots... more

That old chestnut

It's an oldie but a goody, the one about the two perpendicular polarizers and a 3rd one is placed in between at 45°. Surprise surprise light... more

Sometimes I wonder

Amalie and I have often wondered how you get circularly polarized light. Actually I have often wondered Amalie is proably a first time wonderer.... more

    Hi Chris, Do you have a link to the answer sheet for this one?

    Kirchoff's test
    Hi Nick; The current through the lower resistor is negative (this means it is in the other direction to that drawn) so, taking the loop clockwise, the potential drop across it will be positive. -14.4 +12 +2.4 = 0 I like to use Potential...

    Kirchoff's test
    Hi there Mr. Hamper, Thank you, InThinking has been a wonderful resource for me as I teach IB physics for the first time. However, I believe this test has an error. When I substitute the values you found for the currents back into the resistors...

    Yes, including stuff like that in appendices would be fine.

    Thanks Chris (very sorry for my wrong spelling earlier!!) Would it be OK if students put sample calculations or details of how they used a kind of software, e.g. audacity, in appendices? I guess appendices are not included in the word count.

    I don't think it is necessary to show example calculations, it would detract from the flow of the essay. I mean that they can use other methods like standard deviation or statistical methods that are beyond the course. Max min method is OK...

    Hi Kris, In EE *Do student's have to show sample calculations and explain how they obtained uncertainty or would quoting on the table correctly be sufficient? *What do you mean by "Process data ... or similar to find the uncertainties."? Would...
