Ammonium phosphate

                                            Ammonium phosphate Ammonium phosphate  is an ammonium  salt of orthophosphoric acid. It is a highly unstable compound with the  formula (NH 4 ) 3 PO 4 . Because of its instability, it is elusive and of no commercial value. A related "double salt", (NH 4 ) 3 PO 4 . (NH 4 ) 2 HPO 4  is also recognized but is too unstable for practical use. Both triammonium salts evolve ammonia. In contrast to the unstable nature of the triammonium salts, the  diammonium phosphate (NH 4 ) 2 HPO 4  monoammonium salt (NH 4 )H 2 PO 4,  are stable materials that are commonly used as fertilizers to provide plants with fixed nitrogen and phosphorus. PREPARATION OH AMMONIUM TRIPHOSPHATE Triammonium phosphate can be prepared in the laboratory by treating 85% phosphoric acid with 30% ammonia solution: ...

Aryabhatta

                                      Aryabhatta Aryabhatta was the first Indian mathematician and astronomer. He had immense knowledge in the field of mathematics. Moreover, he did he may discoveries during his era. For instance, some of them were the discovery of algebraic identities, trigonometrical functions, the value of pi, Place value system, etc. Aryabhatta was born in 475 A.D. Furthermore his birthplace eas not sure, but in his book the ‘Aryabhatiya’, he mentions that he was a native of Kusumapura the modern-day Patna. Moreover, from his historical records, the archaeologists believed that he continued his further studies in Kusumapura. Because in Kusumapura his major astronomical observatory was located. Therefore, we can ascertain that Aryabhatta spent most of the time there. Further, some historians believe that he was also the head of Nalanda University in Kusumpura. ...

ALBERT EINSTEIN

                    ALBERT EINSTEIN Albert Einstein was born on 14 March 1879 in the German city of Ulm, without any indication that he was destined for greatness. On the contrary, his mother thought Albert was a freak. To her, his head seemed much too large. At the age of two-a-half, Einstein still wasn't talking. When he finally did learn to speak, he uttered everything twice. Einstein did not know what to do with other children, and his playmates called him "Brother Boring." So the youngster played by himself much of the time. He especially loved mechanical toys. Looking at his newborn sister, Maja, he is said to have said: "Fine but where are her wheels?" A headmaster once told his father that what Einstein chose as a profession wouldn't matter, because"he'll never make a success at anything." Einstein began learning to play the violin at the age of six, because his mother wanted him to;  he later became a violinist, m...
