The last date for TUM was 31 May. So if you were applying for masters, you are late. But anyway Ask them. Maybe they will permit you to apply late as well.
I cant give you my essay. But I can surely help you regarding it.
My essay was around 900 words
Which one do you want help on
I wrote on Data explosion
There were 4 paragraphs.
First one provides an introduction to Data Explosion. What is specifically means by data explosion and what is causing it
Second para introducing informatics ( how it differs from IT) and how it can be used to device solutions to problems such as data Explosion. By "How" I mean if you look at the definition of Informatics and think about it, you will get an idea of how. Consult wikipedia for that.
3rd and fourth paragraphs contained examples of data explosion and how informatics can be used to help device solutions to them. If you search on the internet you will get atleast one example of DATa explosion and its proposed and available solutions courtest of informatics.
5 para was Akhtitamiya ( Ending). Think about how informatics can help in ways other than Devicing solution like looking at the bigger picture of impacts of technologies made possible with informatics. Have a look at other topics. You can get an idea from them. I did and I wrote about it.
Hope this was helpful. Anymore??. Msg me.!!
