Re: BdMO National 2012: Higher Sec, Sec, Junior 01, Primary

সুব্রত চিঠি পাঠাই ২৪ ঘণ্টা পর মানে ১ দিন পর
রুপন্তি পাই ২৫ ঘণ্টা পর অর্থাৎ {১ + (১/২৪) }

n দিন পর সুব্রত চিঠি পাঠাই আর রুপন্তি পাই {n + (n/24)} দিনে

এভাবে তো ২৫ তম দিনে রুপন্তি যে চিঠি পাই শেতা সুব্রত এর ২৪ তম চিঠি......।/??????????? কিংকর্তব্যবিমুঢ়............

Re: Light Years

I want to know with "what" it is measured and how. Suppose the distance between "X" and "Y" is 1000 light years. You can't measure this by scale. So how can you measure this?
