খাইসে রে,মেলা কিছু দেখি জানতাম না! তানভীর ভাইকে ধন্যবাদ! :-) "It is not known with certainty how planets are formed. The prevailing theory is that they are formed during the collapse of a nebula into a thin disk of gas and dust. A protostar forms at the core, surrounded by a rotating protoplanetary ...

Re: Your opinion

Re: Gravitation
hmmm... now i think i am understanding a little! Maybe you are indicating if there's any inverse force against $G$. (But you told energy! :-S)
I don't think there's any. From where did you come up with this idea? It would help me to answer better then!

Re: Gravitation
I am sorry... I didn't get your question exactly? Would you please explain a bit more?
Do you mean Gravitational potential? It is negative too!

Re: Dhaka Higher Secondary 2010/7
I think question statement should be a little bit refined. The part "Every scout was said to handshake with each other. Some of them did not do ." should be replaced by something like "Every scout was said to handshake with each other. But some of them didn't handshake with all ." I first considered...

ঠিকই আছে!
উদাহরণস্বরুপ, ধরা যাক, $ s^2 $ এর স্থানে তুমি ২৫ বসাইতেসো! তাইলে কি আসবে খেয়াল করো!
$ s^2=25 $ সুতরাং, $ n=s^2 $ বসাইলে আমরা পাই,
\[ \lfloor \sqrt{25}+\sqrt{25+1}\rfloor = \lfloor { 5 + 5.1} \rfloor\ = 10 = 2s \]
