Colour Blindness


When you’re colour blind such as I am (for green and red) you know you can’t do certain jobs involving green and red lights, but I didn’t know until recently that experimental physics specialised in optics was one of those jobs. This year I had to do an experiment with an michelson morely interferometer, an device that initially gave one of the many hints that led to special relativity namely an indication that the speed of light was really a constant. What we (me and my lab partner) had to do however was use it to create a spectrum of various light sources (what wavelength/colour of light is present in the light source and with what intensity) one of the things we had to do to achieve this goal is make sure the interference gave a nice pattern that should look a little like a  rainbow, well what I saw was something grey that at the point where the interference was really perfect started to look a little like a rainbow, my lab partner not being colour blind on the other had had an much easier time detecting the rainbow like interference, so much easier that I really couldn’t see anything at all when he already began to see the rainbow. I don’t want to be an experimental physicist anyway theory is my way to go, but when I wasn’t so sure about that I thought that if I was going to be an experimental physicist I would like to specialise in optics. Well at least I like math a lot more than most other people do.

Making offline backups


A lot of sites on the internet will stay online for a relatively long time such as Wikipedia, facebook etc. But not all webpage’s are as permanent as the before mentioned, especially webpage’s from college or universities courses aren’t always that permanent, therefore it is important for students to make offline backups if you want to use online recourses of a course you followed in the future. The easiest way (in my experience) to do so is to make a map for the website first save the course website itself in htm, and after that save the links you want to keep in the same directory if you don’t change any of the names while saving the files you should get an working offline backup of the website.

MIT online courses


Being a physics student I sometimes watch videos at MIT opencourseware and when I do I always find it a little weird that some of their undergraduate courses have stuff in them that is thought in highschool in my country. It’s not that strange if you consider that in the USA children aren’t split up  into 3 levels (vwo, havo and vmbo) which means that highschool courses can’t get the difficulty and speed they have in the Netherlands or other countries where children split based on intelligence.

Here are some of the courses I found a lot of highschool material in:

Microecnonomics

Classical Mechanics
