Hi guys! Hope you're well!

Firstly, if you go into Starbucks today before 12 you can get a free latté, i'm definitely going to pop in this morning. Sit in there and read for a bit I think.

Well not much to report.

Got up yesterday, had breakfast and went into town. Bought these French curves and some things for lunch and came back again... took my photos for the day.

Similar to day 1

You pull up a white screen on your computer and prop up anything really plasticy such as a ruler, protractor, CD case etc etc... and then with a polarising filter you twist until the the planes don't allow light through this makes the screen appear black. The plastic then distorts the polarised light so it can get through the filter. Engineers used to use this to test stress and strain on models.

Polarised light is light in on plane, vertical or horizontal.

Say these:

| | | | | | | | |

Are light rays coming out your computer towards you.

The polarising filter is essentially lots of tiny lines with gaps between where the light can pass:

| | | | | | | | |

 

However, when we twist the filter, we change the gaps which the light can pass through too:

/ / / / / / / /

This will reduce the amount of light passing through. We can continue to rotate it round to 90degrees.

No vertically polarised light will be able to pass through like this. Except distorted light which happens as it passes through the plastic.

Started explaining it and got a bit carried away!

Little vid I made sort of showing the effect:

Spent the rest of the day doing a ground floor plan for my building which took ALL DAY. from 2 ish til 11 with a break for lunch and dinner.

I've got 4 more to do and 4 days to do them in. Super week this is planning out to be hehe

 

Have a great day guys, enjoy your coffee if you pick one up!
