QUES: Following a series of arcade game successes in the early 1980s, Nintendo made plans to create a cartridge-based console called the Famicom. Masayuki Uemura designed the system. Original plans called for an advanced 16-bit system which would function as a full-fledged computer with a keyboard and floppy disk drive, but Nintendo president Hiroshi Yamauchi rejected this and instead decided to go for a cheaper, more conventional cartridge-based game console as he felt that features such as keyboards and disks were intimidating to non-technophiles. A test model was constructed in October 1982 to verify the functionality of the hardware, after which work began on programming tools. Because 65xx CPUs had not been manufactured or sold in Japan up to that time, no cross-development software was available and it had to be produced from scratch. Early Famicom games were written on a system that ran on an NEC PC-8001 computer and LEDs on a grid were used with a digitizer to design graphics as no software design tools for this purpose existed at that time.[citation needed]
 Who designed the Pamicom system?

QUES: Uranium-238 is the most stable isotope of uranium, with a half-life of about 4.468×109 years, roughly the age of the Earth. Uranium-235 has a half-life of about 7.13×108 years, and uranium-234 has a half-life of about 2.48×105 years. For natural uranium, about 49% of its alpha rays are emitted by each of 238U atom, and also 49% by 234U (since the latter is formed from the former) and about 2.0% of them by the 235U. When the Earth was young, probably about one-fifth of its uranium was uranium-235, but the percentage of 234U was probably much lower than this.
About how old is the Earth?

ANS: 4.468×109 years

QUES: The Kingdoms of England and Scotland were unified in 1707 creating the Kingdom of Great Britain. Following an attempted republican revolution in Ireland in 1798, the Kingdoms of Ireland and Great Britain were unified in 1801, creating the United Kingdom. The Isle of Man and the Channel Islands remaining outside of the United Kingdom but with their ultimate good governance being the responsibility of the British Crown (effectively the British government). Although, the colonies of North American that would become the United States of America were lost by the start of the 19th century, the British Empire expanded rapidly elsewhere. A century later it would cover one third of the globe. Poverty in the United Kingdom remained desperate however and industrialisation in England led to terrible condition for the working class. Mass migrations following the Irish Famine and Highland Clearances resulted in the distribution of the islands' population and culture throughout the world and a rapid de-population of Ireland in the second-half of the 19th century. Most of Ireland seceded from the United Kingdom after the Irish War of Independence and the subsequent Anglo-Irish Treaty (1919–1922), with the six counties that formed Northern Ireland remaining as an autonomous region of the UK.
When did the Kingdoms of Great Britain and Ireland unite?

ANS: 1801

QUES: Two groups G and H are called isomorphic if there exist group homomorphisms a: G → H and b: H → G, such that applying the two functions one after another in each of the two possible orders gives the identity functions of G and H. That is, a(b(h)) = h and b(a(g)) = g for any g in G and h in H. From an abstract point of view, isomorphic groups carry the same information. For example, proving that g • g = 1G for some element g of G is equivalent to proving that a(g) ∗ a(g) = 1H, because applying a to the first equality yields the second, and applying b to the second gives back the first.
From what point of view do isomorphic groups have different information?
