Well,I am back and this time it is again to do with cooking.(Bear with me guys,this is as big as an adventure for me as travelling in the Himalayas or learning Taekwondo.Don't worry it'll end in a few days)Tried to cook noodles yesterday and though it got cooked,I ended up putting too much water and had to have noodle soup in the end. Had an okay day in terms of college.Lectures and practicals as usual. From now on,I thought of sharing some of my work with you.The reasons are twofold.People hardly know what physics students learn.So,I feel it would be interesting for my readers to find out.Secondly,it helps me in summarising the things I have learnt that particular day. Did some logic circuits today.What are they used for?Well,in our day to day life,we try to find what is right and wrong.We try to establish parity;how equal is one thing with another.We try to juxtapose 2 things together and obtain a resultant answer. Logic circuits are exactly that,except that they are used in computers and other electronic devices. This is a highly simplified explanation of why we use logical circuits.
